Approved June 21, 2007.

If an individual taxpayer files a Federal income tax return on or before the due date for that return (including extensions), and if the IRS does not timely provide a notice to that taxpayer specifically stating the taxpayer’s liability and the basis for that liability, then the IRS must suspend any interest, penalty, addition to tax, or additional amount with respect to any failure relating to the return that is computed by reference to the period of time the failure continues and that is properly allocable to the suspension period. A notice is timely if provided before the close of the eighteen-month period (thirty-six month period, in the case of notices provided after November 25, 2007) beginning on the later of the date on which the return is filed or the due date of the return without regard to extensions. The suspension period begins on the day after the close of the eighteen-month period (or thirty-six month period) and ends twenty-one days after the IRS provides the notice. This suspension rule applies separately with respect to each item or adjustment.

The proposed regulations provide guidance on applying section 6404(g) to amended returns and other signed documents that show an increased tax liability, as well as to amended returns that show a decreased tax liability. If, on or after December 21, 2005, a taxpayer provides to the IRS an amended return or other signed written document showing an additional tax liability, then the eighteen-month period (or thirty-six month period) does not begin to run with respect to the items that gave rise to the additional tax liability until that return or other signed written document is provided to the IRS. This rule is mandated by GOZA section 303(b). Except as provided in GOZA section 303(b), the filing of an amended return has no effect on the running of the eighteen-month period (or thirty-six month period) under section 6404(g). Accordingly, if a taxpayer files an amended return or other signed written document showing a decrease in tax liability and the IRS at any time proposes to adjust the changed item or items, any interest, penalty, addition to tax, or additional amount with respect to the changed item or items on the amended return or other signed written document will not be suspended. If married taxpayers file a return claiming a change in filing status to married filing jointly, the general rule authorizing suspension will not apply unless each spouse’s separate return, if required to be filed, was timely. An amended return or other written document is provided to the IRS for purposes of these proposed regulations when it is received by the IRS.

Notice to the taxpayer must be in writing and specifically state the amount of the liability and the basis for the liability. The notice must provide the taxpayer with sufficient information to identify which items of income, deduction, loss, or credit the IRS has adjusted or proposes to adjust, and the reason for that adjustment. Administrative proceedings pertaining to adjustments to partnership items of partnerships subject to the unified audit and litigation procedures of Subchapter C of Chapter 63 of Subtitle F of the Internal Revenue Code (TEFRA) occur at the partnership level. Each partner has the right to participate in partnership-level administrative proceedings. The tax matters partner (TMP) of a TEFRA partnership has a fiduciary relationship to the partners and must provide the partners with information concerning significant administrative proceedings and actions within 30 days of the action or the receipt of information concerning the partnership matter. TEFRA partnership administrative proceedings at the partnership level concern the treatment of partnership items and the partners’ allocable shares of those items rather than the specific tax liability of each partner attributable to the partnership items. Partners can, however, compute the specific tax attributable to adjustments to partnership items based on their interests in the partnership, so notice to the TMP concerning the treatment of partnership items constitutes notice to the partners under section 6404(g).

The general rule for suspension does not apply to (1) any penalty imposed by section 6651 for failing to file a tax return or for failing to pay tax; (2) any interest, penalty, addition to tax, or additional amount in a case involving fraud; (3) any interest, penalty, addition to tax, or additional amount with respect to any tax liability shown on a return; (4) any interest, penalty, addition to tax, or additional amount with respect to any gross misstatement; (5) any interest, penalty, addition to tax, or additional amount with respect to any reportable transaction not meeting the disclosure requirement of section 6664(d)(2)(A) or any listed transaction as defined in section 6707A(c); and (6) any criminal penalty.

The proposed regulations limit the exception pertaining to a case involving fraud to the taxpayer and the taxable year in issue. The proposed regulations also provide that the exception in section 6404(g) for “a case involving fraud” means that fraud on the return with respect to any item will preclude suspension under section 6404(g) with respect to all items on the return.

AJCA section 903(b) added subparagraph (D), pertaining to gross misstatements, to section 6404(g)(2), effective for taxable years beginning after December 31, 2003. The proposed regulations define “gross misstatement” as the reporting of any item on the original or any amended return if that item is attributable to a gross valuation misstatement as defined in section 6662(h), a substantial omission of income as described in section 6501(e)(1) or section 6229(c), or a frivolous position or a desire to delay or impede the administration of the Federal income tax laws as described in section 6702.

Section 6404(g)(2)(C) provides that interest suspension does not apply to any tax liability shown on a return. Consistent with this exception, any interest, penalty, addition to tax, or additional amount with respect to an erroneous tentative carryback or refund adjustment will not be suspended because the disallowance of the erroneous tentative carryback or refund adjustment does not change the tax liability originally shown on the taxpayer’s return. An election under section 183(e) to defer the determination as to whether the presumption applies that an activity is engaged in for profit tolls the notification period and the suspension period described in section 6404(g)(1), in that the election calls for the IRS to defer proposing adjustments regarding the activity.

This section lists the paragraphs contained in §§301.6404-1 through 301.6404-4.

Par. 3. Section 301.6404-4 is added to read as follows:

(a) Suspension—(1) In general. Except as provided in paragraph (b) of this section, if an individual taxpayer files a return of tax imposed by subtitle A on or before the due date for the return (including extensions) and the Internal Revenue Service (IRS) does not timely provide the taxpayer with a notice specifically stating the amount of any increased liability and the basis for that liability, then the IRS must suspend any interest, penalty, addition to tax, or additional amount with respect to any failure relating to the return. This suspension is computed by reference to the period of time the failure continues to exist. The notice described in this paragraph (a)(1) is timely if provided before the close of the eighteen-month period (thirty-six month period in the case of notices provided after November 25, 2007) beginning on the later of the date on which the return is filed or the due date of the return without regard to extensions.

(2) Treatment of amended returns and other documents—(i) Amended returns filed on or after December 21, 2005, that show an increase in tax liability. If a taxpayer, on or after December 21, 2005, provides to the IRS an amended return or one or more other signed written documents showing an increase in tax liability, the date on which the return was filed will, for purposes of this paragraph (a), be the date on which the last of the documents was provided. Documents described in this paragraph (a)(2)(i) are provided on the date that they are received by the IRS.

(ii) Amended returns that show a decrease in tax liability. If a taxpayer provides to the IRS an amended return or other signed written document that shows a decrease in tax liability, any interest, penalty, addition to tax, or additional amount will not be suspended if the IRS at any time proposes to adjust the changed item or items on the amended return or other signed written document.

(iii) Amended return and other documents as notice. As to the items reported, an amended return or one or more other signed written documents showing that the taxpayer owes an additional amount of tax for the taxable year serves as the notice described in paragraph (a)(1) of this section.

(iv) Joint return after filing separate return. A joint return filed under section 6013(b) is subject to the rules for amended returns described in this paragraph (a)(2). The IRS will not suspend any interest, penalty, addition to tax, or additional amount on a joint return filed under section 6013(b) unless each spouse, if required to file a return, filed a timely separate return.

(3) Separate application. This paragraph (a) shall be applied separately with respect to each item or adjustment.

(4) Duration of suspension period. The suspension period described in paragraph (a)(1) of this section begins the day after the close of the eighteen-month period (thirty-six month period, in the case of notices provided after November 25, 2007) beginning on the later of the date on which the return is filed or the due date of the return without regard to extensions. The suspension period ends twenty-one days after the earlier of the date on which the IRS mails the required notice to the taxpayer’s last known address, the date on which the required notice is hand-delivered to the taxpayer, or the date on which the IRS receives an amended return or other signed written document showing an increased liability.

(5) Example. The following example illustrates the rules of this paragraph (a):

Example. An individual taxpayer timely files an income tax return for taxable year 2004 on the due date of the return, April 15, 2005. On December 11, 2006, the taxpayer mails to the IRS an amended return reporting an additional item of income and an increased tax liability for taxable year 2004. The IRS receives the amended return on December 13, 2006. On January 16, 2007, the IRS provides the taxpayer with a notice stating that the taxpayer has an additional tax liability based on the disallowance of a deduction the taxpayer claimed on his original return and did not change on his amended return. The date the amended return was received substitutes for the date that the original return was filed with respect to the additional item of tax liability reported on the amended return. Thus, the IRS will not suspend interest, penalties, additions to tax, or additional amounts with respect to the additional item of income and the increased tax liability reported on the amended return. The suspension period for the additional tax liability based on the IRS’ disallowance of the deduction begins on October 15, 2006, so the IRS will suspend interest, penalties, additions to tax, and additional amounts with respect to the disallowed deduction and additional tax liability from that date through February 6, 2007, which is twenty-one days after the IRS provided notice of the additional tax liability and the basis for that liability.

(6) Notice of liability and the basis for the liability—(i) In general. Notice to the taxpayer must be in writing and specifically state the amount of the liability and the basis for the liability. The notice must provide the taxpayer with sufficient information to identify which items of income, deduction, loss, or credit the IRS has adjusted or proposes to adjust, and the reason for that adjustment. Notice of the reason for the adjustment does not require a detailed explanation or a citation to any Internal Revenue Code section or other legal authority. The IRS does not have to incorporate all the information necessary to satisfy the notice requirement within a single document or provide all the information at the same time. Documents that may contain information sufficient to qualify as notice, either alone or in conjunction with other documents, include, but are not limited to, statutory notices of deficiency, examination reports (for example, Forms 4549 “Income Tax Examination Changes,” Forms 886-A “Explanation of Items”), Forms 870 “Waiver of Restrictions on Assessment and Collection of Deficiency in Tax and Acceptance of Overassessment,” notices of proposed deficiency that allow the taxpayer an opportunity for review in the Office of Appeals (30-day letters), notices pursuant to section 6213(b) (mathematical or clerical errors), and notice and demand for payment of a jeopardy assessment under section 6861.

(ii) Tax attributable to TEFRA partnership items. Notice to the partner or the tax matters partner (TMP) of a partnership subject to the Unified Audit and Litigation Procedures of subchapter C of chapter 63 of subtitle F of the Internal Revenue Code (TEFRA) that provides specific information about the basis for the adjustments to partnership items is sufficient notice if a partner could reasonably compute the specific tax attributable to the partnership item based on the proposed adjustments as applied to the partner’s individual tax situation. Documents provided by the IRS during a TEFRA partnership proceeding that may contain information sufficient to satisfy the notice requirements include, but are not limited to, a Notice of Final Partnership Administrative Adjustment, examination reports (for example, Forms 4549, Forms 886-A), or a letter that allows the partners an opportunity for review in the Office of Appeals (60-day letter).

(iii) Examples. The following examples illustrate the rules of this paragraph (a)(6).

Example 1. During an audit of Taxpayer A’s 2005 taxable year return, the IRS questions a charitable deduction claimed on the return. The IRS provides A with a “30-day letter” that proposes a deficiency of $1,000 based on the disallowance of the charitable deduction and informs A that A may file a written protest of the proposed deficiency to the Office of Appeals within 30 days. The letter includes as an attachment a copy of the revenue agent’s report that states that “It has not been established that the amount shown on your return as a charitable contribution was paid during the tax year. Therefore, this deduction is not allowable.” The information in the 30-day letter and attachment provides A with notice of the specific amount of the liability and the basis for that liability as described in this paragraph (a).

Example 2. Taxpayer B is a partner in partnership P, a TEFRA partnership for taxable year 2005. B claims a distributive share of partnership income on B’s Federal income tax return for 2005 filed on April 17, 2006. On October 1, 2007, during the course of a partnership audit of P for taxable year 2005, the IRS provides P’s TMP a “60-day letter” proposing to adjust P’s income by $10,000. The IRS had previously provided the TMP with a copy of the examination report explaining that the adjustment was based on $10,000 of unreported net income. On October 31, 2007, P’s TMP informs B of the proposed adjustment as required by §301.6223(g)-1(b). By accounting for B’s distributive share of the $10,000 of unreported income from P with B’s other income tax items, B can determine B’s tax attributable to the $10,000 partnership adjustment. The information in the 60-day letter and the examination report allows B to compute the specific amount of the liability attributable to the adjustment to the partnership item and the basis for that adjustment and therefore satisfies the notice requirement of paragraph (a). Because the IRS provided that notice to the TMP, B’s agent under the TEFRA partnership provisions, within eighteen months of the April 17, 2006, filing date of B’s return, any interest, penalty, addition to tax, or additional amount with respect to B’s tax liability attributable to B’s distributive share of the $10,000 of unreported partnership income will not be suspended under section 6404(g).

(7) Providing notice by the IRS—(i) In general. The IRS may provide notice by mail or in person to the taxpayer or the taxpayer’s representative. If the IRS mails the notice, it must be sent to the taxpayer’s last known address under rules similar to section 6212(b), except that certified or registered mail is not required. Notice is considered provided as of the date of mailing or delivery in person.

(ii) Providing notice in TEFRA partnership proceedings. In the case of TEFRA partnership proceedings, the IRS must provide notice of final partnership administrative adjustments (FPAA) by mail to those partners specified in section 6223. Within 60 days of an FPAA being mailed, the TMP is required to forward notice of the FPAA to those partners not entitled to direct notice from the IRS under section 6223. Certain partners with small interests in partnerships with more than 100 partners may form a Notice Group and designate a partner to receive the FPAA on their behalf. The IRS may provide other information after the beginning of the partnership administrative proceeding to the TMP who, in turn, must provide that information to the partners specified in §301.6223(g)-1 within 30 days of receipt. Pass-thru partners who receive notices and other information from the IRS or the TMP must forward that notice or information within 30 days to those holding an interest through the pass-thru partner. Information provided by the IRS to the TMP is deemed to be notice for purposes of this section to those partners specified in §301.6223(g)-1 as of the date the IRS provides that notice to the TMP. A similar rule applies to notice provided to the designated partner of a Notice Group, and to notice provided to a pass-thru partner. In the foregoing situations, the TMP, designated partner, and pass-thru partner are agents for direct and indirect partners. Consequently, notice to these agents is deemed to be notice to the partners for whom they act.

(b) Exceptions—(1) Failure to file tax return or to pay tax. Paragraph (a) of this section does not apply and interest will not be suspended with respect to any penalty imposed by section 6651.

(2) Fraud. Paragraph (a) of this section does not apply and interest will not be suspended with respect to any interest, penalty, addition to tax, or additional amount in a case involving fraud. Fraud has the same meaning in this paragraph (b) as in section 6501(c)(1) and is not attributed from one taxpayer to another taxpayer. If a taxpayer files a fraudulent return for one year, paragraph (a) of this section may apply to any other tax year of the taxpayer that does not involve fraud. Fraud affecting one item on a return precludes paragraph (a) of this section from applying to any other items on that return.

(3) Tax shown on return. Paragraph (a) of this section does not apply and interest will not be suspended with respect to any interest, penalty, addition to tax, or additional amount with respect to any tax liability shown on a return.

(4) Gross misstatement—(i) Description. Paragraph (a) of this section does not apply and interest will not be suspended with respect to any interest, penalty, addition to tax, or additional amount with respect to a gross misstatement. A gross misstatement for purposes of this paragraph (b) means—

(A) A substantial omission of income as described in section 6501(e)(1) or section 6229(c)(2);

(B) A gross valuation misstatement within the meaning of section 6662(h); or

(C) A misstatement to which the penalty under section 6702(a) applies.

(ii) If a gross misstatement occurs, then interest will not be suspended with respect to any items of income omitted from the return and with respect to overstated deductions, even though one or more of the omitted items would not constitute a substantial omission, gross valuation misstatement, or misstatement to which section 6702(a) applies.

(5) [Reserved].

(c) Special rules—(1) Tentative carryback and refund adjustments. If an amount applied, credited, or refunded under section 6411 exceeds the overassessment properly attributable to a tentative carryback or refund adjustment, any interest, penalty, addition to tax, or additional amount with respect to the excess will not be suspended.

(2) Election under section 183(e). If a taxpayer elects under section 183(e) to defer the determination as to whether the presumption applies that an activity is engaged in for profit, the 18-month (or 36-month) notification period described in paragraph (a)(1) of this section or, if that period has passed as of the date the election is made, the suspension period described in paragraph (a)(4) of this section will be tolled for the period to which the election applies. Tolling will begin on the date the election is made and end on the later of the date the return for the last taxable year to which the election applies is filed or is due without regard to extensions.

(d) Effective/applicability date. The rules of this section apply as of the date of publication of a Treasury decision adopting these rules as final regulations in the Federal Register.

Section 4965(c) defines the term “tax-exempt entity” for section 4965 purposes by reference to sections 501(c), 501(d), 170(c), 7701(a)(40), 4979(e) (paragraphs (1), (2) and (3)), 529, 457(b), and 4973(a). The proposed regulations describe the types of entities captured by the statutory cross-references in section 4965(c).

Section 4965(e) defines the term “prohibited tax shelter transaction” by reference to section 6707A(c)(1) and (c)(2). In accordance with the statutory definition, the proposed regulations define the term “prohibited tax shelter transaction” by reference to the definition of the term “reportable transaction” in section 6707A(c)(1) and (c)(2) and the regulations under section 6011. The proposed regulations define a subsequently listed transaction as a transaction (other than a reportable transaction within the meaning of section 6707A(c)(1)) to which a tax-exempt entity becomes a party before the transaction becomes a listed transaction within the meaning of section 6707A(c)(2).

Several commentators expressed concern over the severe penalties imposed on tax-exempt entities and entity managers for participating in many common and legitimate transactions which have no tax avoidance purpose, yet may fall within the definition of prohibited tax shelter transaction. The commentators suggested that the IRS and the Treasury Department carve out certain types of transactions from the definition of “prohibited tax shelter transaction” or revise current listing procedures to give taxpayers an opportunity to object to the identification of a specific transaction as a tax avoidance transaction. Some commentators recommended that any future published guidance which designates a transaction as a listed or reportable transaction be issued with a prospective effective date and state that it will not apply retroactively. Several commentators requested that the proposed regulations identify listed, subsequently listed, confidential and contractual protection transactions that would not be treated as prohibited tax shelter transactions for purposes of section 4965. The above recommendations are not adopted in these proposed regulations because section 4965 defines the term “prohibited tax shelter transaction” by reference to the existing reportable transaction regime. Any additions to, or exclusions from, the definition of reportable transactions, or any changes to the current listing procedures, must be made within the framework of section 6011 rather than section 4965.

One commentator suggested that the term “reportable transaction” should be narrowly interpreted for purposes of section 4965. However, this term already has been defined under section 6011, and consequently, these proposed regulations interpret it consistently for section 4965 and section 6011 purposes.

Excise taxes under section 4965 apply only if a tax-exempt entity is a party to a prohibited tax shelter transaction. A number of commentators requested guidance in determining when a tax-exempt entity is a party to a prohibited tax shelter transaction. Notice 2007-18 defined the term party as a tax-exempt entity that facilitates a prohibited tax shelter transaction by reason of its tax-exempt, tax indifferent or tax-favored status. The proposed regulations incorporate this definition of the term party. Notice 2007-18 also notified the public that the IRS and the Treasury Department would provide a broader definition of the term party in future guidance in accordance with section 4965. Consistent with Notice 2007-18, the proposed regulations define the term party for purposes of sections 4965 and 6033(a)(2) to include a tax-exempt entity that enters into a listed transaction and reflects on its tax return a reduction or elimination of its liability for applicable Federal employment, excise or unrelated business income taxes that is derived directly or indirectly from tax consequences or tax strategy described in the published guidance that lists the transaction.

Several commentators specifically requested that the proposed regulations address under what circumstances, if any, a tax-exempt entity may be treated as a party to a prohibited tax shelter transaction if the tax-exempt entity is an investor in a partnership, hedge fund or other conduit. Invoking the language in the legislative history to section 4965, commentators recommended that the IRS and Treasury Department establish a rule or a safe harbor that would treat an investor in an indirect investment activity as being a party for section 4965 purposes only in limited circumstances.

As illustrated by an example in the proposed regulations, a tax-exempt entity does not become a party to a prohibited tax shelter transaction solely because it invests in an entity that in turn becomes involved in a prohibited tax shelter transaction. To be considered a “party” under the proposed regulations, the tax-exempt entity must either facilitate the prohibited tax shelter transaction by reason of its tax-exempt, tax indifferent or tax-favored status, or must treat the prohibited tax shelter transaction on its tax return as reducing or eliminating its own Federal tax liability. The IRS and the Treasury Department request comments on any further clarifications that may be helpful in reflecting the intended application of the statute as expressed in the legislative history.

The proposed regulations clarify the definition of the term “entity manager” in section 4965(d) and provide guidance on persons who could be entity managers pursuant to a delegation of authority from other entity managers.

The proposed regulations also define the term “approve or otherwise cause.” Under section 4965(a)(2), an entity manager may be liable for the manager-level excise tax only if the manager “approves such entity as (or otherwise causes such entity to be) a party” to a prohibited tax shelter transaction and knows or has reason to know the transaction is a prohibited tax shelter transaction. The proposed regulations generally limit the definition of “approving or otherwise causing” to affirmative actions of persons who, individually or as members of a collective body, have the authority to commit the entity to the transaction.

One commentator requested guidance on whether entity managers may be liable for section 4965 taxes in successor-in-interest situations. Several commentators requested guidance on the consequences under section 4965 of the exercise or nonexercise of certain options pursuant to the terms of the transaction. In response to these comments, the proposed regulations provide rules for successor-in-interest situations and the consequences of the exercise or nonexercise of certain options.

The level of tax imposed on the tax-exempt entity under section 4965(b)(1) depends upon whether the entity knows or has reason to know, at the time it enters into the transaction, that it is becoming a party to a prohibited tax shelter transaction. The liability of the entity manager for the tax under section 4965(b)(2) depends on whether the entity manager knows or has reason to know that the transaction is a prohibited tax shelter transaction at the time of approving or otherwise causing the entity to be a party to the transaction. The proposed regulations treat the entity as knowing or having reason to know if its manager(s) knew or had to reason to know and provide rules for determining whether entity managers knew or had reason to know. The “reason-to-know” rules in these proposed regulations are consistent with the “reason-to-know” and “should have known” standards under other provisions of the Code.

Commentators recommended that the IRS and the Treasury Department not treat receipt of a disclosure statement regarding a transaction by the tax-exempt entity as conclusive evidence that the tax-exempt entity knew or had reason to know that the transaction was a prohibited tax shelter transaction. The proposed regulations adopt this recommendation and provide that receipt by an entity manager of a disclosure statement in advance of a transaction is a relevant factor but, by itself, does not necessarily demonstrate that the tax-exempt entity or any of its managers knew or had reason to know that the transaction was a prohibited tax shelter transaction.

Section 4965(b)(1) provides the rules for computing the entity-level excise tax with respect to prohibited tax shelter transactions. Section 4965(b)(2) imposes a flat $20,000 excise tax on any entity manager that approved or otherwise caused the entity to become a party to a prohibited tax shelter transaction. The proposed regulations follow the computational rules in the statute, define the term “taxable year” for purposes of determining the entity-level tax under section 4965, and clarify the timing of the entity manager taxes under section 4965. The proposed regulations provide that entity manager liability for section 4965 taxes is not joint and several.

The proposed regulations define the terms “net income” and “proceeds” for section 4965 purposes and provide rules regarding the allocation of net income or proceeds attributable to a prohibited tax shelter transaction to various periods, including the appropriate treatment of net income or proceeds received prior to the effective date of the section 4965(a) tax.

Commentators recommended that net income for purposes of section 4965 be determined in a manner consistent with the determination of net income for other purposes of the Code. The proposed regulations adopt this recommendation.

Numerous commentators requested guidance in determining what amounts constitute proceeds for section 4965 purposes and urged the IRS and the Treasury Department to limit the definition of proceeds to the tax-exempt entity’s economic return from the transaction. One commentator recommended that return of basis and return of capital be excluded from the definition of proceeds as these amounts are arguably not “attributable to” a prohibited tax shelter transaction. Several commentators recommended that the IRS and the Treasury Department adopt a rule that would exclude from proceeds earnings on certain set-aside amounts that are used to defease the tax-exempt entity’s obligations under so-called sale-in, lease-out (SILO) and lease-in, lease-out (LILO) transactions. See Notice 2000-15, 2000-1 C.B. 826, and Notice 2005-13, 2005-1 C.B. 630. Several commentators suggested that nonexercise of options to repurchase in the SILO / LILO context should not be treated as giving rise to net income or proceeds.

The proposed regulations define the term proceeds separately for tax-exempt entities that are involved in prohibited tax shelter transactions to facilitate the tax avoidance of others and tax-exempt entities that are involved in listed transactions for their own tax benefit. In the case of tax-exempt entities that are involved in prohibited tax shelter transactions to facilitate the tax avoidance of others, the proposed regulations define proceeds as the gross amount of the tax-exempt entity’s consideration for facilitating the transaction, not reduced by any costs or expenses attributable to the transaction. This definition subjects the tax-exempt party’s economic return from the transaction to the entity-level excise tax. In the case of tax-exempt entities that are involved in listed transactions to reduce or eliminate their own tax liability, the proposed regulations define the term proceeds as tax savings purportedly generated by the transaction and claimed by the tax-exempt entity in the tax year.

In Notice 2007-18, the IRS and Treasury Department provided that the allocation of net income and proceeds is determined according to normal tax accounting rules. The proposed regulations incorporate this rule both for purposes of allocating amounts to pre- and post-effective date periods, and allocating amounts to pre- and post-listing periods where a subsequently listed transaction is involved. Under the proposed regulations, tax-exempt entities that have not adopted a method of accounting are required to use the cash method. Several commentators recommended that the IRS adopt a position that net income or proceeds from pre-enactment transactions would not be properly allocable to any periods after the effective date of the section 4965(a) tax. The IRS and the Treasury Department decline to adopt this blanket rule because such rule would be inconsistent with established principles of tax accounting and would conflict with the plain language of the effective date provisions in section 516 of TIPRA.

In accordance with section 516(d) of TIPRA, the proposed regulations provide that the taxes under section 4965 are effective for taxable years ending after May 17, 2006, with respect to transactions entered into before, on or after such date, except that no tax under section 4965(a) applies with respect to income or proceeds that are properly allocable to any period ending on or before August 15, 2006. The proposed regulations also provide that the 100 percent entity-level tax under section 4965(b)(1)(B) with respect to knowing transactions does not apply to prohibited tax shelter transactions entered into by a tax-exempt entity on or before May 17, 2006 and that the IRS will not assert an entity manager tax under section 4965(b)(2) with respect to any prohibited tax shelter transaction entered into by a tax-exempt entity on or before May 17, 2006. In addition, the proposed regulations provide that the 100 percent entity-level tax under section 4965(b)(1)(B) and the entity manager tax under section 4965(b)(2) do not apply with respect to any subsequently listed transaction.

Numerous commentators questioned whether it would be appropriate to apply the new excise taxes to pre-enactment transactions that already have closed and advocated a narrow application of the new excise taxes to pre-enactment transactions. The commentators argued that it would be unfair to apply the new excise taxes to pre-enactment transactions that have already closed and subject tax-exempt entities to unforeseen, harsh penalties. The commentators recommended that all transactions closed prior to May 17, 2006 be “delisted” for purposes of section 4965. The proposed regulations do not adopt these recommendations as they are inconsistent with the statutory effective date of section 4965 and the statutory definition of prohibited tax shelter transaction.

When finalized, the regulations under section 4965 are proposed to be applicable for taxable years ending after July 6, 2007. Taxpayers may rely on these proposed regulations for periods ending on or before such date.

Section 6033(a)(2), as amended by TIPRA, requires every tax-exempt entity that is a party to a prohibited tax shelter transaction to disclose to the IRS, in such form and manner and at such time as determined by the Secretary, such entity’s being a party to such transaction and the identity of any other party to the transaction which is known to the tax-exempt entity. The statute gives the IRS discretion with respect to the form, manner and timing of this disclosure. The proposed regulations provide rules regarding the form, manner and timing of this disclosure. With respect to the due date for the disclosure, the proposed regulations provide that, in the case of tax-exempt entities that are involved in prohibited tax shelter transactions to facilitate the tax avoidance of others, the disclosure must be filed by May 15 of the calendar year following the close of the calendar year during which the tax-exempt entity entered into the prohibited tax shelter transaction (or, in the case of subsequently listed transactions, by May 15 of the calendar year following the close of the calendar year during which the transaction was identified by the Secretary as a listed transaction). In the case of tax-exempt entities that are involved in listed transactions to reduce or eliminate their own tax liability, the proposed regulations provide that the disclosure must be filed on or before the date on which the first tax return (whether an original or an amended return) is filed on which the tax-exempt entity reflects a reduction or elimination of its liability for applicable Federal employment, excise or unrelated business income taxes that is derived directly or indirectly from tax consequences or tax strategy described in the published guidance that lists the transaction.

Temporary regulations providing the same rules are being issued concurrently with these proposed regulations.

The temporary regulations under section 6033(a)(2) apply to disclosures with respect to transactions entered into by a tax-exempt entity after May 17, 2006. Transition relief is provided with respect to transactions entered into during a transition period beginning on May 18, 2006 and ending on December 31, 2006. The due date for the disclosure with respect to the transactions entered into during the transition period is November 5, 2007 or, in the case of tax-exempt entities that are involved in listed transactions to reduce or eliminate their own tax liability, the later of: the date on which the first tax return (whether an original or an amended return) is filed on which the tax-exempt entity reflects a reduction or elimination of its liability for applicable Federal employment, excise or unrelated business income taxes that is derived directly or indirectly from tax consequences or tax strategy described in the published guidance that lists the transaction; or November 5, 2007.

Section 6011(g), as amended by TIPRA, requires any taxable party to a prohibited tax shelter transaction to notify any tax-exempt entity which is a party to such transaction that the transaction is a prohibited tax shelter transaction. The statute is silent as to how and when the section 6011(g) disclosure needs to be made. The proposed regulations provide rules regarding the form, timing and frequency of the section 6011(g) disclosure. The proposed regulations also explain to whom the section 6011(g) disclosure must be made. With respect to the due date for the disclosure, the proposed regulations provide that the disclosure to each tax-exempt entity that is a party to the transaction must be made within 60 days after the last to occur of: (1) the date the taxable person becomes a taxable party to the transaction; or (2) the date the taxable party knows or has reason to know that the tax-exempt entity is a party to the transaction. No disclosure is required if the taxable party does not know or have reason to know that the tax-exempt entity is a party to the transaction on or before the first date on which the transaction is required to be disclosed by the taxable party under §§1.6011-4, 20.6011-4, 25.6011-4, 31.6011-4, 53.6011-4, 54.6011-4, or 56.6011-4.

One commentator recommended that the IRS provide an exception to the disclosure requirements for any transactions for which there would be no income or proceeds subject to the taxes imposed by section 4965. The proposed regulations do not adopt this recommendation because one of the purposes of section 6011(g) disclosure is to notify the tax-exempt entity that it may have a disclosure obligation under section 6033(a)(2) with respect to the transaction.

When finalized, the proposed regulations under section 6011(g) will apply to disclosures with respect to transactions entered into by a tax-exempt entity after May 17, 2006.

The proposed regulations amend the existing regulations under sections 6011 and 6071 to specify the forms that must be used to pay section 4965 taxes and to provide the due dates for filing these forms. With respect to the due dates, the proposed regulations provide that a return of the entity-level excise tax under section 4965 must be made on or before the due date (not including extensions) for filing the tax-exempt entity’s annual information return under section 6033(a)(1). If the tax-exempt entity is not required to file an annual information return, the return of section 4965 taxes must be made on or before the 15^th day of the fifth month after the end of the tax-exempt entity’s annual accounting period. A return of manager-level excise tax under section 4965 must be made on or before the 15^th day of the fifth month following the close of the entity manager’s taxable year during which the entity entered into the prohibited tax shelter transaction.

Temporary regulations providing the same rules are being issued concurrently with these proposed regulations.

A commentator recommended that the IRS and the Treasury Department not make the section 4965 excise taxes effective prior to the issuance of final regulations in cases where application of the new law or provisions of the new law is unclear. The proposed regulations do not adopt this recommendation because the effective date for the section 4965 taxes is statutory.

One commentator recommended that the IRS waive the excise taxes under section 4965 in appropriate circumstances. The proposed regulations do not adopt this recommendation as the obligation to pay section 4965 taxes flows directly from the statute, which does not authorize the IRS to waive the entity-level or manager-level taxes.

The amendments and additions to the regulations under sections 6011 and 6071 will be effective on July 6, 2007. Transition relief is provided with respect to returns of section 4965 taxes due on or before October 4, 2007. These returns will be deemed timely if the return is filed and the tax paid before October 4, 2007.

[The text of the proposed amendment to §1.6033-5(a) through (g)(1) is the same as the text of §1.6033-5T (a) through (g)(1) published elsewhere in this issue of the Bulletin].

(a) Entity-level excise tax. Section 4965 imposes two excise taxes with respect to certain tax shelter transactions to which tax-exempt entities are parties. Section 4965(a)(1) imposes an entity-level excise tax on certain tax-exempt entities that are parties to “prohibited tax shelter transactions,” as defined in section 4965(e). See §53.4965-2 for the discussion of covered tax-exempt entities. See §53.4965-3 for the definition of prohibited tax shelter transactions. See §53.4965-4 for the definition of tax-exempt party to a prohibited tax shelter transaction. The entity-level excise tax under section 4965(a)(1) is imposed on a specified percentage of the entity’s net income or proceeds that are attributable to the transaction for the relevant tax year (or a period within that tax year). The rate of tax depends on whether the entity knew or had reason to know that the transaction was a prohibited tax shelter transaction at the time the entity became a party to the transaction. See §53.4965-7(a) for the discussion of the entity-level excise tax under section 4965(a)(1). See §53.4965-6 for the discussion of “knowing or having reason to know.” See §53.4965-8 for the definition of net income and proceeds and the standard for allocating net income and proceeds that are attributable to a prohibited tax shelter transaction to various periods.

(b) Manager-level excise tax. Section 4965(a)(2) imposes a manager-level excise tax on “entity managers,” as defined in section 4965(d), of tax-exempt entities who approve the entity as a party (or otherwise cause the entity to be a party) to a prohibited tax shelter transaction and know or have reason to know, at the time the tax-exempt entity enters into the transaction, that the transaction is a prohibited tax shelter transaction. See §53.4965-5 for the definition of entity manager and the meaning of “approving or otherwise causing,” and §53.4965-6 for the discussion of “knowing or having reason to know.” See §53.4965-7(b) for the discussion of the manager-level excise tax under section 4965(a)(2).

(c) Effective/applicability dates. See §53.4965-9 for the discussion of the relevant effective dates.

(a) In general. Under section 4965(c), the term “tax-exempt entity” refers to entities that are described in sections 501(c), 501(d), or 170(c) (other than the United States), Indian tribal governments (within the meaning of section 7701(a)(40)), and tax-qualified pension plans, individual retirement arrangements and similar tax-favored savings arrangements that are described in sections 4979(e)(1), (2) or (3), 529, 457(b), or 4973(a). The tax-exempt entities referred to in section 4965(c) are divided into two broad categories, non-plan entities and plan entities.

(b) Non-plan entities. Non-plan entities are—

(1) Entities described in section 501(c);

(2) Religious or apostolic associations or corporations described in section 501(d);

(3) Entities described in section 170(c), including states, possessions of the United States, the District of Columbia, political subdivisions of states and political subdivisions of possessions of the United States (but not including the United States); and

(4) Indian tribal governments within the meaning of section 7701(a)(40).

(c) Plan entities. Plan entities are—

(1) Entities described in section 4979(e)(1) (qualified plans under section 401(a), including qualified cash or deferred arrangements under section 401(k) (including a section 401(k) plan that allows designated Roth contributions));

(2) Entities described in section 4979(e)(2) (annuity plans described in section 403(a));

(3) Entities described in section 4979(e)(3) (annuity contracts described in section 403(b), including a section 403(b) arrangement that allows Roth contributions);

(4) Qualified tuition programs described in section 529;

(5) Eligible deferred compensation plans under section 457(b) that are maintained by a governmental employer as defined in section 457(e)(1)(A);

(6) Arrangements described in section 4973(a) which include—

(i) Individual retirement plans defined in sections 408(a) and (b), including—

(A) Simplified employee pensions (SEPs) under section 408(k);

(B) Simple individual retirement accounts (SIMPLEs) under section 408(p);

(C) Deemed individual retirement accounts or annuities (IRAs) qualified under a qualified plan (deemed IRAs) under section 408(q)); and

(D) Roth IRAs under section 408A.

(ii) Arrangements described in section 220(d) (Archer Medical Savings Accounts (MSAs));

(iii) Arrangements described in section 403(b)(7) (custodial accounts treated as annuity contracts);

(iv) Arrangements described in section 530 (Coverdell education savings accounts); and

(v) Arrangements described in section 223(d) (health savings accounts (HSAs)).

(a) In general. Under section 4965(e), the term prohibited tax shelter transaction means—

(1) Listed transactions within the meaning of section 6707A(c)(2), including subsequently listed transactions described in paragraph (b) of this section; and

(2) Prohibited reportable transactions, which consist of the following reportable transactions within the meaning of section 6707A(c)(1)—

(i) Confidential transactions, as described in §1.6011-4(b)(3) of this chapter; or

(ii) Transactions with contractual protection, as described in §1.6011-4(b)(4) of this chapter.

(b) Subsequently listed transactions. A subsequently listed transaction for purposes of section 4965 is a transaction that is identified by the Secretary as a listed transaction after the tax-exempt entity has entered into the transaction and that was not a prohibited reportable transaction (within the meaning of section 4965(e)(1)(C) and paragraph (a)(2) of this section) at the time the entity entered into the transaction.

(c) Cross-reference. The determination of whether a transaction is a listed transaction or a prohibited reportable transaction for section 4965 purposes shall be made under the law applicable to section 6707A(c)(1) and (c)(2).

(a) In general. For purposes of sections 4965 and 6033(a)(2), a tax-exempt entity is a party to a prohibited tax shelter transaction if the entity—

(1) Facilitates a prohibited tax shelter transaction by reason of its tax-exempt, tax indifferent or tax-favored status;

(2) Enters into a listed transaction and the tax-exempt entity’s tax return (whether an original or an amended return) reflects a reduction or elimination of its liability for applicable Federal employment, excise or unrelated business income taxes that is derived directly or indirectly from tax consequences or tax strategy described in the published guidance that lists the transaction; or

(3) Is identified in published guidance, by type, class or role, as a party to a prohibited tax shelter transaction.

(b) Published guidance may identify which tax-exempt entities, by type, class or role, will not be treated as a party to a prohibited tax shelter transaction for purposes of sections 4965 and 6033(a)(2).

(c) Examples. The following examples illustrate the principles of this section:

Example 1. A tax-exempt entity enters into a transaction (Transaction A) with an S corporation. Transaction A is the same as or substantially similar to the transaction identified by the Secretary as a listed transaction in Notice 2004-30, 2004-1 C.B. 828. The tax-exempt entity’s role in Transaction A is similar to the role of the tax-exempt party, as described in Notice 2004-30. Under the terms of the transaction, as described in Notice 2004-30, the tax-exempt entity receives the S corporation stock and, due to the tax-exempt entity’s tax-exempt status, aids the S corporation and its shareholders in avoiding taxable income. The tax-exempt entity facilitates Transaction A by reason of its tax-exempt, tax indifferent or tax-favored status. Accordingly, the tax-exempt entity is a party to Transaction A for purposes of sections 4965 and 6033(a)(2). See §601.601(d)(2)(ii)(b) of this chapter.

Example 2. A tax-exempt entity is a partner in a partnership. The partnership has a number of other taxable and tax-exempt partners. The tax-exempt entity does not control the partnership. The partnership enters into a number of transactions, including a transaction (Transaction B) which is the same as or substantially similar to the transaction identified by the Secretary as a listed transaction in Notice 2002-35, 2002-1 C.B. 992 (as clarified and modified by Notice 2006-16, 2006-1 C.B. 538). The partnership’s role in Transaction B is similar to the role of T, as described in Notice 2002-35, that is, the role of the taxpayer claiming the tax benefits from the transaction. The tax-exempt entity’s tax returns do not reflect a reduction or elimination of its liability for applicable Federal taxes as a result of Transaction B. The tax and economic consequences from Transaction B to the other partners are not dependent on the tax-exempt entity’s tax-exempt, tax indifferent or tax-favored status. Accordingly, the tax-exempt entity does not facilitate Transaction B by reason of its tax-exempt, tax indifferent or tax-favored status. Because the tax-exempt entity’s tax returns do not reflect a reduction or elimination of its liability for applicable Federal taxes that is derived directly or indirectly from tax consequences or tax strategy described in the published guidance that lists the transaction, the tax-exempt entity is not a party to Transaction B by reason of paragraph (a)(2) of this section. The tax-exempt entity also has not been identified, by type, class or role, as a party to a prohibited tax shelter transaction in published guidance. Therefore, the tax-exempt entity is not a party to Transaction B for purposes of sections 4965 and 6033(a)(2). See §601.601(d)(2)(ii)(b) of this chapter.

(d) Effective dates. See §53.4965-9 for the discussion of the relevant applicability dates.

(a) Entity manager of a non-plan entity—(1) In general. Under section 4965(d)(1), an entity manager of a non-plan entity is—

(i) A person with the authority or responsibility similar to that exercised by an officer, director, or trustee of an organization (that is, the non-plan entity); and

(ii) With respect to any act, the person who has final authority or responsibility (either individually or as a member of a collective body) with respect to such act.

(2) Definition of officer. For purposes of paragraph (a)(1)(i) of this section, a person is considered to be an officer of the non-plan entity (or to have similar authority or responsibility) if the person—

(i) Is specifically designated as such under the certificate of incorporation, by-laws, or other constitutive documents of the non-plan entity; or

(ii) Regularly exercises general authority to make administrative or policy decisions on behalf of the non-plan entity.

(3) Exception for acts requiring approval by a superior. With respect to any act, any person is not described in paragraph (a)(2)(ii) of this section if the person has authority merely to recommend particular administrative or policy decisions, but not to implement them without approval of a superior.

(4) Delegation of authority. A person is an entity manager of a non-plan entity within the meaning of paragraph (a)(1)(ii) of this section if, with respect to any prohibited tax shelter transaction, such person has been delegated final authority or responsibility with respect to such transaction (including by transaction type or dollar amount) by a person described in paragraph (a)(1)(i) of this section or the governing board of the entity. For example, an investment manager is an entity manager with respect to a prohibited tax shelter transaction if the non-plan entity’s governing body delegated to the investment manager the final authority to make certain investment decisions and, in the exercise of that authority, the manager committed the entity to the transaction. To be considered an entity manager of a non-plan entity within the meaning of paragraph (a)(1)(ii) of this section, a person need not be an employee of the entity. A person is not described in paragraph (a)(1)(ii) of this section if the person is merely implementing a decision made by a superior.

(b) Entity manager of a plan entity—(1) In general. Under section 4965(d)(2), an entity manager of a plan entity is the person who approves or otherwise causes the entity to be a party to the prohibited tax shelter transaction.

(2) Special rule for plan participants and beneficiaries who have investment elections—(i) Fully self-directed plans or arrangements. In the case of a fully self-directed qualified plan, IRA, or other savings arrangement (including the case where a plan participant or beneficiary is given a list of prohibited investments, such as collectibles), if the plan participant or beneficiary selected a certain investment and, therefore, approved the plan entity to become a party to a prohibited tax shelter transaction, the plan participant or the beneficiary is an entity manager.

(ii) Plans or arrangements with limited investment options. In the case of a qualified plan, IRA, or other savings arrangement where a plan participant or beneficiary is offered a limited number of investment options from which to choose, the person responsible for determining the pre-selected investment options is an entity manager and the plan participant or the beneficiary generally is not an entity manager.

(c) Meaning of “approves or otherwise causes”—(1) In general. A person is treated as approving or otherwise causing a tax-exempt entity to become a party to a prohibited tax shelter transaction if the person has the authority to commit the entity to the transaction, either individually or as a member of a collective body, and the person exercises that authority.

(2) Collective bodies. If a person shares the authority described in paragraph (c)(1) of this section as a member of a collective body (for example, board of trustees or committee), the person will be considered to have exercised such authority if the person voted in favor of the entity becoming a party to the transaction. However, a member of the collective body will not be treated as having exercised the authority described in paragraph (c)(1) of this section if he or she voted against a resolution that constituted approval or an act that caused the tax-exempt entity to be a party to a prohibited tax shelter transaction, abstained from voting for such approval, or otherwise failed to vote in favor of such approval.

(3) Exceptions—(i) Successor in interest. If a tax-exempt entity that is a party to a prohibited tax shelter transaction is dissolved, liquidated, or merged into a successor entity, an entity manager of the successor entity will not, solely by reason of the reorganization, be treated as approving or otherwise causing the successor entity to become a party to a prohibited tax shelter transaction, provided that the reorganization of the tax-exempt entity does not result in a material change to the terms of the transaction. For purposes of this paragraph, a material change includes an extension or renewal of the agreement (other than an extension or renewal that results from another party to the transaction unilaterally exercising an option granted by the agreement) or a more than incidental change to any payment under the agreement. A change for the sole purpose of substituting the successor entity for the original tax-exempt party is not a material change.

(ii) Exercise or nonexercise of options. Nonexercise of an option pursuant to a transaction involving the tax-exempt entity generally will not constitute an act of approving or causing the entity to be a party to the transaction. If, pursuant to a transaction involving the tax-exempt entity, the entity manager exercises an option (such as a repurchase option), the entity manager will not be subject to the entity manager-level tax if the exercise of the option does not result in the tax-exempt entity becoming a party to a second transaction that is a prohibited tax shelter transaction.

(4) Example. The following example illustrates the principles of paragraph (c)(3)(ii) of this section:

Example. In a sale-in, lease-out (SILO) transaction described in Notice 2005-13, 2005-1 C.B. 630, X, which is a non-plan entity, has purported to sell property to Y, a taxable entity and lease it back for a term of years. At the end of the basic lease term, X has the option of “repurchasing” the property from Y for a predetermined purchase price, with funds that have been set aside at the inception of the transaction for that purpose. The entity manager, by deciding to exercise or not exercise the “repurchase” option is not approving or otherwise causing the non-plan entity to become a party to a second prohibited tax shelter transaction. See §601.601(d)(2)(ii)(b) of this chapter.

(5) Coordination with the reason-to-know standard. The determination that an entity manager approved or caused a tax-exempt entity to be a party to a prohibited tax shelter transaction, by itself, does not establish liability for the section 4965(a)(2) tax. For rules on determining whether an entity manager knew or had reason to know that the transaction was a prohibited tax shelter transaction, see §53.4965-6(b).

(d) Effective dates. See §53.4965-9 for the discussion of the relevant applicability dates.

(a) Attribution to the entity. An entity will be treated as knowing or having reason to know for section 4965 purposes if one or more of its entity managers knew or had reason to know that the transaction was a prohibited tax shelter transaction at the time the entity manager(s) approved the entity as (or otherwise caused the entity to be) a party to the transaction. The entity shall be attributed the knowledge or reason to know of any entity manager described in §53.4965-5(a)(1)(i) even if that entity manager does not approve the entity as (or otherwise cause the entity to be) a party to the transaction.

(b) Determining whether an entity manager knew or had reason to know—(1) In general. Whether an entity manager knew or had reason to know that a transaction is a prohibited tax shelter transaction is based on all facts and circumstances. In order for an entity manager to know or have reason to know that a transaction is a prohibited tax shelter transaction, the entity manager must have knowledge of sufficient facts that would lead a reasonable person to conclude that the transaction is a prohibited tax shelter transaction. An entity manager will be considered to have “reason to know” if a reasonable person in the entity manager’s circumstances would conclude that the transaction was a prohibited tax shelter transaction based on all the facts reasonably available to the manager at the time of approving the entity as (or otherwise causing the entity to be) a party to the transaction. Factors that will be considered in determining whether a reasonable person in the entity manager’s circumstances would conclude that the transaction was a prohibited tax shelter transaction include, but are not limited to—

(i) The presence of tax shelter indicia (see paragraph (b)(2) of this section);

(ii) Whether the entity manager received a disclosure statement prior to the consummation of the transaction indicating that the transaction may be a prohibited tax shelter transaction (see paragraph (b)(3) of this section); and

(iii) Whether the entity manager made appropriate inquiries into the transaction (see paragraph (b)(4) of this section).

(2) Tax-shelter indicia. The presence of indicia that a transaction is a tax shelter will be treated as an indication that the entity manager knew or had reason to know that the transaction was a prohibited tax shelter transaction. Tax shelter indicia include but are not limited to—

(i) The transaction is extraordinary for the entity considering prior investment activity;

(ii) The transaction promises an economic return for the organization that is exceptional considering the amount invested by, the participation of, or the absence of risk to the organization; or

(iii) The transaction is of significant size relative to the receipts of the entity.

(3) Effect of disclosure statements. Receipt by an entity manager of a statement, including a statement described in section 6011(g), in advance of a transaction that the transaction may be a prohibited tax shelter transaction (or a statement that a partnership, hedge fund or other investment conduit may engage in a prohibited tax shelter transaction in the future) is a factor relevant in the determination of whether the entity manager knew or had reason to know that the transaction is a prohibited transaction. However, an entity manager will not be treated as knowing or having reason to know that the transaction was a prohibited tax shelter transaction solely because the entity manager receives such a disclosure.

(4) Appropriate inquiries. What inquiries are appropriate will be determined from the facts and circumstances of each case. For example, if one or more tax shelter indicia are present or if an entity manager receives a disclosure statement described in paragraph (b)(3) of this section, an entity manager has a responsibility to inquire further whether the transaction is a prohibited tax shelter transaction.

(c) Reliance on professional advice—(1) In general. An entity manager is not required to obtain the advice of a professional tax advisor to establish that the entity manager made appropriate inquiries. Moreover, not seeking professional advice, by itself, shall not give rise to an inference that the entity manager had reason to know that a transaction is a prohibited tax shelter transaction.

(2) Reliance on written opinion of professional tax advisor. An entity manager may establish that he or she did not have a reason to know that a transaction was a prohibited tax shelter transaction at the time the tax-exempt entity entered into the transaction if the entity manager reasonably, and in good faith, relied on the written opinion of a professional tax advisor. Reliance on the written opinion of a professional tax advisor establishes that the entity manager did not have reason to know if, taking into account all the facts and circumstances, the reliance was reasonable and the entity manager acted in good faith. For example, the entity manager’s education, sophistication, and business experience will be relevant in determining whether the reliance was reasonable and made in good faith. In no event will an entity manager be considered to have reasonably relied in good faith on an opinion unless the requirements of this paragraph (c)(2) are satisfied. The fact that these requirements are satisfied, however, will not necessarily establish that the entity manager reasonably relied on the opinion in good faith. For example, reliance may not be reasonable or in good faith if the entity manager knew, or reasonably should have known, that the advisor lacked knowledge in the relevant aspects of Federal tax law.

(i) All facts and circumstances considered. The advice must be based upon all pertinent facts and circumstances and the law as it relates to those facts and circumstances. The requirements of this paragraph (c)(2) are not satisfied if the entity manager fails to disclose a fact that it knows, or reasonably should know, is relevant to determining whether the transaction is a prohibited tax shelter transaction.

(ii) No unreasonable assumptions. The advice must not be based on unreasonable factual or legal assumptions (including assumptions as to future events) and must not unreasonably rely on the representations, statements, findings, or agreements of the entity manager or any other person (including another party to the transaction or a material advisor within the meaning of sections 6111 and 6112.

(iii) “More likely than not” opinion. The written opinion of the professional tax advisor must apply the appropriate law to the facts and, based on this analysis, must conclude that the transaction was not a prohibited tax shelter transaction at a “more likely than not” level of certainty at the time the entity manager approved the entity (or otherwise caused the entity) to be a party to the transaction.

(3) Special rule. An entity manager‘s reliance on a written opinion of a professional tax advisor will not be considered reasonable if the advisor is, or is related to a person who is, a material advisor with respect to the transaction within the meaning of sections 6111 and 6112.

(d) Subsequently listed transactions. An entity manager will not be treated as knowing or having reason to know that a transaction (other than a prohibited reportable transaction as defined in section 4965(e)(1)(C) and §53.4965-3(a)(2)) is a prohibited tax shelter transaction if the entity enters into the transaction before the date on which the transaction is identified by the Secretary as a listed transaction.

(e) Effective/applicability dates. See §53.4965-9 for the discussion of the relevant applicability dates.

(a) Entity-level taxes—(1) In general. Entity-level excise taxes apply to non-plan entities (as defined in §53.4965-2(b)) that are parties to prohibited tax shelter transactions.

(i) Prohibited tax shelter transactions other than subsequently listed transactions—(A) Amount of tax if the entity did not know and did not have reason to know. If the tax-exempt entity did not know and did not have reason to know that the transaction was a prohibited tax shelter transaction at the time the entity entered into the transaction, the tax is the highest rate of tax under section 11 multiplied by the greater of—

(1) The entity’s net income with respect to the prohibited tax shelter transaction (after taking into account any tax imposed by Subtitle D, other than by this section, with respect to such transaction) for the taxable year; or

(2) 75 percent of the proceeds received by the entity for the taxable year that are attributable to such transaction.

(B) Amount of tax if the entity knew or had reason to know. If the tax-exempt entity knew or had reason to know that the transaction was a prohibited tax shelter transaction at the time the entity entered into the transaction, the tax is the greater of—

(1) 100 percent of the entity’s net income with respect to the transaction (after taking into account any tax imposed by Subtitle D, other than by this section, with respect to such transaction) for the taxable year; or

(2) 75 percent of the proceeds received by the entity for the taxable year that are attributable to such transaction.

(ii) Subsequently listed transactions—(A) In general. In the case of a subsequently listed transaction (as defined in section 4965(e)(2) and §53.4965-3(b)), the tax-exempt entity’s income and proceeds attributable to the transaction are allocated between the period before the transaction became listed and the period beginning on the date the transaction became listed. See §53.4965-8 for the standard for allocating net income or proceeds to various periods. The tax for each taxable year is the highest rate of tax under section 11 multiplied by the greater of—

(1) The entity’s net income with respect to the subsequently listed transaction (after taking into account any tax imposed by Subtitle D, other than by this section, with respect to such transaction) for the taxable year that is allocable to the period beginning on the later of the date such transaction is identified by the Secretary as a listed transaction or the first day of the taxable year; or

(2) 75 percent of the proceeds received by the entity for the taxable year that are attributable to such transaction and allocable to the period beginning on the later of the date such transaction is identified by the Secretary as a listed transaction or the first day of the taxable year.

(B) No increase in tax. The 100 percent tax under section 4965(b)(1)(B) and §53.4965-7(a)(1)(i)(B) does not apply to any subsequently listed transaction (as defined in section 4965(e)(2) and §53.4965-3(b)) entered into by a tax-exempt entity before the date on which the transaction is identified by the Secretary as a listed transaction.

(2) Taxable year. The excise tax imposed under section 4965(a)(1) applies for the taxable year in which the entity becomes a party to the prohibited tax shelter transaction and any subsequent taxable year for which the entity has net income or proceeds attributable to the transaction. A taxable year for tax-exempt entities is the calendar year or fiscal year, as applicable, depending on the basis on which the tax-exempt entity keeps its books for Federal income tax purposes. If a tax-exempt entity has not established a taxable year for Federal income tax purposes, the entity’s taxable year for the purpose of determining the amount and timing of net income and proceeds attributable to a prohibited tax shelter transaction will be deemed to be the annual period the entity uses in keeping its books and records.

(b) Manager-level taxes—(1) Amount of tax. If any entity manager approved or otherwise caused the tax-exempt entity to become a party to a prohibited tax shelter transaction and knew or had reason to know that the transaction was a prohibited tax shelter transaction, such entity manager is liable for the $20,000 tax. See §53.4965-5(d) for the meaning of approved or otherwise caused. See §53.4965-6 for the meaning of knew or had reason to know.

(2) Timing of the entity manager tax. If a tax-exempt entity enters into a prohibited tax shelter transaction during a taxable year of an entity manager, then the entity manager that approved or otherwise caused the tax-exempt entity to become a party to the transaction is liable for the entity manager tax for that taxable year if the entity manager knew or had reason to know that the transaction was a prohibited tax shelter transaction.

(3) Example. The application of paragraph (b)(2) of this section is illustrated by the following example:

Example. The entity manager’s taxable year is the calendar year. On December 1, 2006, the entity manager approved or otherwise caused the tax-exempt entity to become a party to a transaction that the entity manager knew or had reason to know was a prohibited tax shelter transaction. The tax-exempt entity entered into the transaction on January 31, 2007. The entity manager is liable for the entity manager level tax for the entity manager’s 2007 taxable year, during which the tax-exempt entity entered into the prohibited tax shelter transaction.

(4) Separate liability. If more than one entity manager approved or caused a tax-exempt entity to become a party to a prohibited tax shelter transaction while knowing (or having reason to know) that the transaction was a prohibited tax shelter transaction, then each such entity manager is separately (that is, not jointly and severally) liable for the entity manager-level tax with respect to the transaction.

(c) Effective dates. See §53.4965-9 for the discussion of the relevant effective dates.

(a) In general. For purposes of section 4965(a), the amount and the timing of the net income and proceeds attributable to the prohibited tax shelter transaction will be computed in a manner consistent with the substance of the transaction. In determining the substance of listed transactions, the IRS will look to, among other items, the listing guidance and any subsequent guidance published in the Internal Revenue Bulletin relating to the transaction.

(b) Definition of net income and proceeds—(1) Net income. A tax-exempt entity’s net income attributable to a prohibited tax shelter transaction is its gross income derived from the transaction reduced by those deductions that are attributable to the transaction and that would be allowed by chapter 1 of the Internal Revenue Code if the tax-exempt entity were treated as a taxable entity for this purpose, and further reduced by taxes imposed by Subtitle D, other than by this section, with respect to the transaction.

(2) Proceeds—(i) Tax-exempt entities that facilitate the transaction by reason of their tax-exempt, tax indifferent or tax-favored status. Solely for purposes of section 4965, in the case of a tax-exempt entity that is a party to the transaction by reason of §53.4965-4(a)(1) of this chapter, the term proceeds means the gross amount of the tax-exempt entity’s consideration for facilitating the transaction, not reduced for any costs or expenses attributable to the transaction. Published guidance with respect to a particular prohibited tax shelter transaction may designate additional amounts as proceeds from the transaction for section 4965 purposes.

(ii) Tax-exempt entities that enter into transactions to reduce or eliminate their liability for applicable Federal taxes. For purposes of section 4965, in the case of a tax-exempt entity that is a party to the transaction by reason of §53.4965-4(a)(2) of this chapter, the term proceeds means tax savings purportedly generated by the transaction and claimed by the tax-exempt entity on its tax return with respect to the tax year. Published guidance with respect to a particular prohibited tax shelter transaction may designate additional amounts as proceeds from the transaction for section 4965 purposes.

(iii) Treatment of gifts and contributions. To the extent not otherwise included in the definition of proceeds in paragraphs (b)(2)(i) and (ii) of this section, any amount that is a gift or a contribution to a tax-exempt entity and is attributable to a prohibited tax shelter transaction will be treated as proceeds for section 4965 purposes, unreduced by any associated expenses.

(c) Allocation of net income and proceeds—(1) In general. For purposes of section 4965(a), the net income and proceeds attributable to a prohibited tax shelter transaction must be allocated in a manner consistent with the tax-exempt entity’s established method of accounting for Federal income tax purposes. If the tax-exempt entity has not established a method of accounting for Federal income tax purposes, solely for purposes of section 4965(a) the tax-exempt entity must use the cash receipts and disbursements method of accounting (cash method) provided for in section 446 of the Internal Revenue Code to determine the amount and timing of net income and proceeds attributable to a prohibited tax shelter transaction.

(2) Special rule. If a tax-exempt entity has established a method of accounting other than the cash method, the tax-exempt entity may nevertheless use the cash method of accounting to determine the amount of the net income and proceeds—

(i) Attributable to a prohibited tax shelter transaction entered into prior to the effective date of section 4965(a) tax and allocable to pre- and post-effective date periods; or

(ii) Attributable to a subsequently listed transaction and allocable to pre- and post-listing periods.

(d) Transition year rules. In the case of the taxable year that includes August 16, 2006 (the transition year), the IRS will treat the period beginning on the first day of the transition year and ending on August 15, 2006, and the period beginning on August 16, 2006, and ending on the last day of the transition year as short taxable years. This treatment is solely for purposes of allocating net income or proceeds under section 4965. The tax-exempt entity continues to file tax returns for the full taxable year, does not file tax returns with respect to these deemed short taxable years and does not otherwise take the short taxable years into account for Federal tax purposes. Accordingly, the net income or proceeds that are properly allocated to the transition year in accordance with this section will be treated as allocable to the period—

(1) Ending on or before August 15, 2006 (and accordingly not subject to tax under section 4965(a)) to the extent such net income or proceeds would have been properly taken into account in accordance with this section by the tax-exempt entity in the deemed short year ending on August 15, 2006; and

(2) Beginning after August 15, 2006 (and accordingly subject to tax under section 4965(a)) to the extent such income or proceeds would have been properly taken into account in accordance with this section by the tax-exempt entity in the short year beginning August 16, 2006.

(e) Allocation to pre- and post-listing periods. If a transaction other than a prohibited reportable transaction (as defined in section 4965(e)(1)(C) and §53.4965-3(a)(2)) to which the tax-exempt entity is a party is subsequently identified in published guidance as a listed transaction during a taxable year of the entity (the listing year) in which it has net income or proceeds attributable to the transaction, the net income or proceeds are allocated between the pre- and post-listing periods. The IRS will treat the period beginning on the first day of the listing year and ending on the day immediately preceding the date of the listing, and the period beginning on the date of the listing and ending on the last day of the listing year as short taxable years. This treatment is solely for purposes of allocating net income or proceeds under section 4965. The tax-exempt entity continues to file tax returns for the full taxable year, does not file tax returns with respect to these deemed short taxable years and does not otherwise take the short taxable years into account for Federal tax purposes. Accordingly, the net income or proceeds that are properly allocated to the listing year in accordance with this section will be treated as allocable to the period—

(1) Ending before the date of the listing (and accordingly not subject to tax under section 4965(a)) to the extent such net income or proceeds would have been properly taken into account in accordance with this section by the tax-exempt entity in the deemed short year ending on the day immediately preceding the date of the listing; and

(2) Beginning on the date of the listing (and accordingly subject to tax under section 4965(a)) to the extent such income or proceeds would have been properly taken into account in accordance with this section by the tax-exempt entity in the short year beginning on the date of the listing.

(f) Examples. The following examples illustrate the allocation rules of this section:

Example 1. (i) In 1999, X, a calendar year non-plan entity using the cash method of accounting, entered into a lease-in/lease-out transaction (LILO) substantially similar to the transaction described in Notice 2000-15, 2000-1 C.B. 826 (describing Rev. Rul. 99-14, 1999-1 C.B. 835, superseded by Rev. Rul. 2002-69, 2002-2 C.B. 760). In 1999, X purported to lease property to Y pursuant to a “head lease,” and Y purported to lease the property back to X pursuant to a “sublease” of a shorter term. In form, X received $268M as an advance payment of head lease rent. Of this amount, $200M had been, in form, financed by a nonrecourse loan obtained by Y. X deposited the $200M with a “debt payment undertaker.” This served to defease both a portion of X’s rent obligation under its sublease and Y’s repayment obligation under the nonrecourse loan. Of the remainder of the $268M advance head lease rent payment, X deposited $54M with an “equity payment undertaker.” This served to defease the remainder of X’s rent obligation under the sublease as well as the exercise price of X’s end-of-sublease term purchase option. This amount inures to the benefit of Y and enables Y to recover its investment in the transaction and a return on that investment. In substance, the $54M is a loan from Y to X. X retained the remaining $14M of the advance head lease rent payment. In substance, this represents a fee for X’s participation in the transaction. See §601.601(d)(2)(ii)(b) of this chapter.

(ii) According to the substance of the transaction, the head lease, sublease and nonrecourse debt will be ignored for Federal income tax purposes. Therefore, any net income or proceeds resulting from these elements of the transaction will not be considered net income or proceeds attributable to the LILO transaction for purposes of section 4965(a). The $54M deemed loan from Y to X and the $14M fee are not ignored for Federal income tax purposes.

(iii) Under X’s established cash basis method of accounting, any net income received in 1999 and attributable to the LILO transaction is allocated to X’s December 31, 1999, tax year for purposes of section 4965. The $14M fee received in 1999, and which constitutes proceeds of the transaction, is likewise allocated to that tax year. Because the 1999 tax year is before the effective date of the section 4965 tax, X will not be subject to any excise tax under section 4965 for the amounts received in 1999.

(iv) Any earnings on the amount deposited with the equity payment undertaker that constitute gross income to X will be reduced by X’s original issue discount deductions with respect to the deemed loan from Y, in determining X’s net income from the transaction.

Example 2. B, a non-plan entity using the cash method of accounting, has an annual accounting period that ends on December 31, 2006. B entered into a prohibited tax shelter transaction on March 15, 2006. On that date, B received a payment of $600,000 as a fee for its involvement in the transaction. B received no other proceeds or income attributable to this transaction in 2006. Under B’s method of accounting, the payment received by B on March 15, 2006, is taken into account in the deemed short year ending on August 15, 2006. Accordingly, solely for purposes of section 4965, the payment is treated as allocable solely to the period ending on or before August 15, 2006, and is not subject to the excise tax imposed by section 4965(a).

Example 3. The facts are the same as in Example 2, except that B received an additional payment of $400,000 on September 30, 2006. Under B’s method of accounting, the payment received by B on September 30, 2006, is taken into account in the deemed short year beginning on August 16, 2006. Accordingly, solely for purposes of section 4965, the $400,000 payment is treated as allocable to the period beginning after August 15, 2006, and is subject to the excise tax imposed by section 4965(a).

Example 4. C, a non-plan entity using the cash method of accounting, has an annual accounting period that ends on December 31. C entered into a prohibited tax shelter transaction on May 1, 2005. On March 15, 2007, C received a payment of $580,000 attributable to the transaction. On June 1, 2007, the transaction is identified by the IRS in published guidance as a listed transaction. On June 15, 2007, C received an additional payment of $400,000 attributable to the transaction. Under C’s method of accounting, the payments received on March 15, 2007, and June 15, 2007, are taken into account in 2007. The IRS will treat the period beginning on January 1, 2007, and ending on May 31, 2007, and the period beginning on June 1, 2007, and ending on December 31, 2007, as short taxable years. The payment received by C on March 15, 2007, is taken into account in the deemed short year ending on May 31, 2007. Accordingly, solely for purposes of section 4965, the payment is treated as allocable solely to the pre-listing period, and is not subject to the excise tax imposed by section 4965(a). The payment received by C on June 15, 2007, is taken into account in the deemed short year beginning on June 1, 2007. Accordingly, solely for purposes of section 4965, the payment is treated as allocable to the post-listing period, and is subject to the excise tax imposed by section 4965(a).

(g) Effective/applicability dates. See §53.4965-9 for the discussion of the relevant applicability dates.

(a) In general. The taxes under section 4965(a) and §53.4965-7 are effective for taxable years ending after May 17, 2006, with respect to transactions entered into before, on or after that date, except that no tax under section 4965(a) applies with respect to income or proceeds that are properly allocable to any period ending on or before August 15, 2006.

(b) Applicability of the regulations. Except as provided in paragraph (c) of this section, upon publication of final regulations, §§53.4965-1 through 53.4965-8 of this chapter will apply to taxable years ending after July 6, 2007. A tax-exempt entity may rely on the provisions of §§53.4965-1 through 53.4965-8 for taxable years ending on or before July 6, 2007.

(c) Effective date with respect to certain knowing transactions—(1) Entity-level tax. The 100 percent tax under section 4965(b)(1)(B) and §53.4965-7(a)(1)(i)(B) does not apply to prohibited tax shelter transactions entered into by a tax-exempt entity on or before May 17, 2006.

(2) Manager-level tax. The IRS will not assert that an entity manager who approved or caused a tax-exempt entity to become a party to a prohibited tax shelter transaction is liable for the entity manager tax under section 4965(b)(2) and §53.4965-7(b)(1) with respect to the transaction if the tax-exempt entity entered into such transaction prior to May 17, 2006.

Par. 5. In §53.6071-1, paragraphs (g) and (h) are added to read as follows:

* * * * *

(g) [The text of the proposed amendment to §53.6071-1(g) is the same as the text of §53.6071-1T(g) published elsewhere in this issue of the Bulletin].

(h) [The text of the proposed amendment to §53.6071-1(h) is the same as the text of §53.6071-1T(h) published elsewhere in this issue of the Bulletin].

* * * * *

(c) [The text of the proposed amendment to §54.6011-1(c) is the same as the text of §54.6011-1T(c) published elsewhere in this issue of the Bulletin].

(d) [The text of the proposed amendment to §54.6011-1(d) is the same as the text of §54.6011-1T(d) published elsewhere in this issue of the Bulletin].

(a) Requirement of disclosure—(1) In general. Except as provided in paragraph (d)(2) of this section, any taxable party (as defined in paragraph (c) of this section) to a prohibited tax shelter transaction (as defined in section 4965(e) and §53.4965-3 of this chapter) must disclose by statement to each tax-exempt entity (as defined in section 4965(c) and §53.4965-2 of this chapter) that the taxable party knows or has reason to know is a party to such transaction (as defined in paragraph (b) of this section) that the transaction is a prohibited tax shelter transaction.

(2) Determining whether a taxable party knows or has reason to know. Whether a taxable party knows or has reason to know that a tax-exempt entity is a party to a prohibited tax shelter transaction is based on all the facts and circumstances. If the taxable party knows or has reason to know that a prohibited tax shelter transaction involves a tax-exempt, tax indifferent or tax-favored entity, relevant factors for determining whether the taxable party knows or has reason to know that a specific tax-exempt entity is a party to the transaction include—

(i) The extent of the efforts made to determine whether a tax-exempt entity is facilitating the transaction by reason of its tax-exempt, tax indifferent or tax-favored status (or is identified in published guidance, by type, class or role, as a party to the transaction); and

(ii) If a tax-exempt entity is facilitating the transaction by reason of its tax-exempt, tax indifferent or tax-favored status (or is identified in published guidance, by type, class or role, as a party to the transaction), the extent of the efforts made to determine the identity of the tax-exempt entity.

(b) Definition of tax-exempt party to a prohibited tax shelter transaction—(1) In general. For purposes of section 6011(g), a tax-exempt entity is a party to a prohibited tax shelter transaction if the entity—

(2) Published guidance may identify which tax-exempt entities, by type, class or role, will not be treated as a party to a prohibited tax shelter transaction for purposes of section 6011(g).

(c) Definition of taxable party—(1) In general. For purposes of this section, the term taxable party means—

(ii) A person who is designated as a taxable party by the Secretary in published guidance.

(2) Special rules—(i) Certain listed transactions. If a transaction that was otherwise not a prohibited tax shelter transaction becomes a listed transaction after the filing of a person’s tax return (including an amended return) reflecting either tax consequences or a tax strategy described in the published guidance listing the transaction (or a tax benefit derived from tax consequences or a tax strategy described in the published guidance listing the transaction), the person is a taxable party beginning on the date the transaction is described as a listed transaction in published guidance.

(ii) Persons designated as non-parties. Published guidance may identify which persons, by type, class or role, will not be treated as a party to a prohibited tax shelter transaction for purposes of section 6011(g).

(d) Time for providing disclosure statement—(1) In general. A taxable party to a prohibited tax shelter transaction must make the disclosure required by this section to each tax-exempt entity that the taxable party knows or has reason to know is a party to the transaction within 60 days after the last to occur of—

(i) The date the person becomes a taxable party to the transaction within the meaning of paragraph (c) of this section; or

(ii) The date the taxable party knows or has reason to know that the tax-exempt entity is a party to the transaction within the meaning of paragraph (b) of this section.

(2) Termination of a disclosure obligation. A person shall not be required to provide the disclosure otherwise required by this section if the person does not know or have reason to know that the tax-exempt entity is a party to the transaction within the meaning of paragraph (b) of this section on or before the first date on which the transaction is required to be disclosed by the person under §§1.6011-4, 20.6011-4, 25.6011-4, 31.6011-4, 53.6011-4, 54.6011-4, or 56.6011-4 of this chapter.

(3) Disclosure is not required with respect to any prohibited tax shelter transaction entered into by a tax-exempt entity on or before May 17, 2006.

(e) Frequency of disclosure. One disclosure statement is required per tax-exempt entity per transaction. See paragraph (h) of this section for rules relating to designation agreements.

(f) Form and content of disclosure statement. The statement disclosing to the tax-exempt entity that the transaction is a prohibited tax shelter transaction must be a written statement that—

(1) Identifies the type of prohibited tax shelter transaction (including the published guidance citation for a listed transaction); and

(2) States that the tax-exempt entity’s involvement in the transaction may subject either it or its entity manager(s) or both to excise taxes under section 4965 and to disclosure obligations under section 6033(a) of the Internal Revenue Code.

(g) To whom disclosure is made. The disclosure statement must be provided—

(1) In the case of a non-plan entity as defined in §53.4965-2(b) of this chapter, to—

(h) Designation agreements. If more than one taxable party is required to disclose a prohibited tax shelter transaction under this section, the taxable parties may designate by written agreement a single taxable party to disclose the transaction. The transaction must then be disclosed in accordance with this section. The designation of one taxable party to disclose the transaction does not relieve the other taxable parties of their obligation to disclose the transaction to a tax-exempt entity that is a party to the transaction in accordance with this section, if the designated taxable party fails to disclose the transaction to the tax-exempt entity in a timely manner.

(i) Penalty for failure to provide disclosure statement. See section 6707A for penalties applicable to failure to disclose a prohibited tax shelter transaction in accordance with this section.

(j) Effective/applicability date. This section will apply with respect to transactions entered into by a tax-exempt entity after May 17, 2006.
