This procedure provides issuers of qualified mortgage bonds (QMBs) and qualified mortgage credit certificates (MCCs) with average area purchase price safe harbors for statistical areas in the United States and with a nationwide average purchase price for residences in the United States for purposes of the QMB rules under section 143 of the Code and the MCC rules under section 25. Rev. Proc. 2006-17 obsoleted in part.

It is the policy of the Internal Revenue Service to announce at an early date whether it will follow the holdings in certain cases. An Action on Decision is the document making such an announcement. An Action on Decision will be issued at the discretion of the Service only on unappealed issues decided adverse to the government. Generally, an Action on Decision is issued where its guidance would be helpful to Service personnel working with the same or similar issues. Unlike a Treasury Regulation or a Revenue Ruling, an Action on Decision is not an affirmative statement of Service position. It is not intended to serve as public guidance and may not be cited as precedent.

Actions on Decisions shall be relied upon within the Service only as conclusions applying the law to the facts in the particular case at the time the Action on Decision was issued. Caution should be exercised in extending the recommendation of the Action on Decision to similar cases where the facts are different. Moreover, the recommendation in the Action on Decision may be superseded by new legislation, regulations, rulings, cases, or Actions on Decisions.

Prior to 1991, the Service published acquiescence or nonacquiescence only in certain regular Tax Court opinions. The Service has expanded its acquiescence program to include other civil tax cases where guidance is determined to be helpful. Accordingly, the Service now may acquiesce or nonacquiesce in the holdings of memorandum Tax Court opinions, as well as those of the United States District Courts, Claims Court, and Circuit Courts of Appeal. Regardless of the court deciding the case, the recommendation of any Action on Decision will be published in the Internal Revenue Bulletin.

The recommendation in every Action on Decision will be summarized as acquiescence, acquiescence in result only, or nonacquiescence. Both “acquiescence” and “acquiescence in result only” mean that the Service accepts the holding of the court in a case and that the Service will follow it in disposing of cases with the same controlling facts. However, “acquiescence” indicates neither approval nor disapproval of the reasons assigned by the court for its conclusions; whereas, “acquiescence in result only” indicates disagreement or concern with some or all of those reasons. “Nonacquiescence” signifies that, although no further review was sought, the Service does not agree with the holding of the court and, generally, will not follow the decision in disposing of cases involving other taxpayers. In reference to an opinion of a circuit court of appeals, a “nonacquiescence” indicates that the Service will not follow the holding on a nationwide basis. However, the Service will recognize the precedential impact of the opinion on cases arising within the venue of the deciding circuit.

The Actions on Decisions published in the weekly Internal Revenue Bulletin are consolidated semiannually and appear in the first Bulletin for July and the Cumulative Bulletin for the first half of the year. A semiannual consolidation also appears in the first Bulletin for the following January and in the Cumulative Bulletin for the last half of the year.

T.C. Memo. 2006-171,

T.C. Docket No. 11634-05L

For purposes of the taxation of fringe benefits under section 61 of the Internal Revenue Code, section 1.61-21(g) of the Income Tax Regulations provides a rule for valuing noncommercial flights on employer-provided aircraft. Section 1.61-21(g)(5) provides an aircraft valuation formula to determine the value of such flights. The value of a flight is determined under the base aircraft valuation formula (also known as the Standard Industry Fare Level formula or SIFL) by multiplying the SIFL cents-per-mile rates applicable for the period during which the flight was taken by the appropriate aircraft multiple provided in section 1.61-21(g)(7) and then adding the applicable terminal charge. The SIFL cents-per-mile rates in the formula and the terminal charge are calculated by the Department of Transportation and are reviewed semi-annually.

The following chart sets forth the terminal charge and SIFL mileage rates:

The Department Store Inventory Price Indexes are prepared on a national basis and include (a) 23 major groups of departments, (b) three special combinations of the major groups — soft goods, durable goods, and miscellaneous goods, and (c) a store total, which covers all departments, including some not listed separately, except for the following: candy, food, liquor, tobacco, and contract departments.

The principal author of this revenue ruling is John Roman Faron of the Office of Associate Chief Counsel (Income Tax and Accounting). For further information regarding this revenue ruling, contact Mr. Faron at (202) 622-4930 (not a toll-free call).

Section 6621 of the Internal Revenue Code establishes the rates for interest on tax overpayments and tax underpayments. Under section 6621(a)(1), the overpayment rate is the sum of the federal short-term rate plus 3 percentage points (2 percentage points in the case of a corporation), except the rate for the portion of a corporate overpayment of tax exceeding $10,000 for a taxable period is the sum of the federal short-term rate plus 0.5 of a percentage point for interest computations made after December 31, 1994. Under section 6621(a)(2), the underpayment rate is the sum of the federal short-term rate plus 3 percentage points.

Section 6621(c) provides that for purposes of interest payable under section 6601 on any large corporate underpayment, the underpayment rate under section 6621(a)(2) is determined by substituting “5 percentage points” for “3 percentage points.” See section 6621(c) and section 301.6621-3 of the Regulations on Procedure and Administration for the definition of a large corporate underpayment and for the rules for determining the applicable date. Section 6621(c) and section 301.6621-3 are generally effective for periods after December 31, 1990.

Section 6621(b)(1) provides that the Secretary will determine the federal short-term rate for the first month in each calendar quarter.

Section 6621(b)(2)(A) provides that the federal short-term rate determined under section 6621(b)(1) for any month applies during the first calendar quarter beginning after such month.

Section 6621(b)(2)(B) provides that in determining the addition to tax under section 6654 for failure to pay estimated tax for any taxable year, the federal short-term rate that applies during the third month following such taxable year also applies during the first 15 days of the fourth month following such taxable year.

Section 6621(b)(3) provides that the federal short-term rate for any month is the federal short-term rate determined during such month by the Secretary in accordance with § 1274(d), rounded to the nearest full percent (or, if a multiple of ¹/₂ of 1 percent, the rate is increased to the next highest full percent).

Notice 88-59, 1988-1 C.B. 546, announced that, in determining the quarterly interest rates to be used for overpayments and underpayments of tax under section 6621, the Internal Revenue Service will use the federal short-term rate based on daily compounding because that rate is most consistent with section 6621 which, pursuant to section 6622, is subject to daily compounding.

Rounded to the nearest full percent, the federal short-term rate based on daily compounding determined during the month of January 2007 is 5 percent. Accordingly, an overpayment rate of 8 percent (7 percent in the case of a corporation) and an underpayment rate of 8 percent are established for the calendar quarter beginning April 1, 2007. The overpayment rate for the portion of a corporate overpayment exceeding $10,000 for the calendar quarter beginning April 1, 2007, is 5.5 percent. The underpayment rate for large corporate underpayments for the calendar quarter beginning April 1, 2007, is 10 percent. These rates apply to amounts bearing interest during that calendar quarter.

Under section 6621(b)(2)(B), the 8 percent rate that applies to estimated tax underpayments for the first calendar quarter in 2007, as provided in Rev. Rul. 2006-63, 2006-52 I.R.B. 1143, also applies to such underpayments for the first 15 days in April 2007.

Interest factors for daily compound interest for annual rates of 5.5 percent, 7 percent, 8 percent, and 10 percent are published in Tables 16, 19, 21, and 25 of Rev. Proc. 95-17, 1995-1 C.B. 556, 570, 573, 575, and 579.

Annual interest rates to be compounded daily pursuant to section 6622 that apply for prior periods are set forth in the tables accompanying this revenue ruling.

The principal author of this revenue ruling is Raymond Bailey of the Office of Associate Chief Counsel (Procedure & Administration). For further information regarding this revenue ruling, contact Mr. Bailey at (202) 622-4910 (not a toll-free call).

This notice provides guidance as to the corporate bond weighted average interest rate and the permissible range of interest rates specified under § 412(b)(5)(B)(ii)(II) of the Internal Revenue Code. In addition, it provides guidance as to the interest rate on 30-year Treasury securities under § 417(e)(3)(A)(ii)(II).

Sections 412(b)(5)(B)(ii) and 412(l)(7)(C)(i), as amended by the Pension Funding Equity Act of 2004 and by the Pension Protection Act of 2006, provide that the interest rates used to calculate current liability and to determine the required contribution under § 412(l) for plan years beginning in 2004 through 2007 must be within a permissible range based on the weighted average of the rates of interest on amounts invested conservatively in long term investment grade corporate bonds during the 4-year period ending on the last day before the beginning of the plan year.

Notice 2004-34, 2004-1 C.B. 848, provides guidelines for determining the corporate bond weighted average interest rate and the resulting permissible range of interest rates used to calculate current liability. That notice establishes that the corporate bond weighted average is based on the monthly composite corporate bond rate derived from designated corporate bond indices. The methodology for determining the monthly composite corporate bond rate as set forth in Notice 2004-34 continues to apply in determining that rate. See Notice 2006-75, 2006-36 I.R.B. 366.

The composite corporate bond rate for February 2007 is 5.85 percent. Pursuant to Notice 2004-34, the Service has determined this rate as the average of the monthly yields for the included corporate bond indices for that month.

The following corporate bond weighted average interest rate was determined for plan years beginning in the month shown below.

Section 417(e)(3)(A)(ii)(II) defines the applicable interest rate, which must be used for purposes of determining the minimum present value of a participant’s benefit under § 417(e)(1) and (2), as the annual rate of interest on 30-year Treasury securities for the month before the date of distribution or such other time as the Secretary may by regulations prescribe. Section 1.417(e)-1(d)(3) of the Income Tax Regulations provides that the applicable interest rate for a month is the annual interest rate on 30-year Treasury securities as specified by the Commissioner for that month in revenue rulings, notices or other guidance published in the Internal Revenue Bulletin.

The rate of interest on 30-year Treasury securities for February 2007 is 4.82 percent. The Service has determined this rate as the average of the yield on the 30-year Treasury bond maturing in February 2036 determined each day through February 7, 2007, and the yield on the 30-year Treasury bond maturing in February 2037 determined each day for the balance of the month.

This revenue procedure provides issuers of qualified mortgage bonds, as defined in section 143(a) of the Internal Revenue Code, and issuers of mortgage credit certificates, as defined in section 25(c), with (1) the nationwide average purchase price for residences located in the United States, and (2) average area purchase price safe harbors for residences located in statistical areas in each state, the District of Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, the Virgin Islands, and Guam.

.01 Section 103(a) provides that, except as provided in section 103(b), gross income does not include interest on any state or local bond. Section 103(b)(1) provides that section 103(a) shall not apply to any private activity bond that is not a “qualified bond” within the meaning of section 141. Section 141(e) provides, in part, that the term “qualified bond” means any private activity bond if such bond (1) is a qualified mortgage bond under section 143, (2) meets the volume cap requirements under section 146, and (3) meets the applicable requirements under section 147.

.02 Section 143(a)(1) provides that the term “qualified mortgage bond” means a bond that is issued as part of a qualified mortgage issue. Section 143(a)(2)(A) provides that the term “qualified mortgage issue” means an issue of one or more bonds by a state or political subdivision thereof, but only if: (i) all proceeds of the issue (exclusive of issuance costs and a reasonably required reserve) are to be used to finance owner-occupied residences; (ii) the issue meets the requirements of subsections (c), (d), (e), (f), (g), (h), (i), and (m)(7) of section 143; (iii) the issue does not meet the private business tests of paragraphs (1) and (2) of section 141(b); and (iv) with respect to amounts received more than 10 years after the date of issuance, repayments of $250,000 or more of principal on mortgage financing provided by the issue are used by the close of the first semiannual period beginning after the date the prepayment (or complete repayment) is received to redeem bonds that are part of the issue.

.03 Section 143(e)(1) provides that an issue of bonds meets the purchase price requirements of section 143(e) if the acquisition cost of each residence financed by the issue does not exceed 90 percent of the average area purchase price applicable to such residence. Section 143(e)(5) provides that, in the case of a targeted area residence (as defined in section 143(j)), section 143(e)(1) shall be applied by substituting 110 percent for 90 percent.

.04 Section 143(e)(2) provides that the term “average area purchase price” means, with respect to any residence, the average purchase price of single-family residences (in the statistical area in which the residence is located) that were purchased during the most recent 12-month period for which sufficient statistical information is available. Under sections 143(e)(3) and (4), respectively, separate determinations are to be made for new and existing residences, and for two-, three-, and four-family residences.

.05 Section 143(e)(2) provides that the determination of the average area purchase price for a statistical area shall be made as of the date on which the commitment to provide the financing is made or, if earlier, the date of the purchase of the residence.

.06 Section 143(k)(2)(A) provides that the term “statistical area” means (i) a metropolitan statistical area (MSA), and (ii) any county (or the portion thereof) that is not within an MSA. Section 143(k)(2)(C) further provides that if sufficient recent statistical information with respect to a county (or portion thereof) is unavailable, the Secretary may substitute another area for which there is sufficient recent statistical information for such county (or portion thereof). In the case of any portion of a State which is not within a county, section 143(k)(2)(D) provides that the Secretary may designate as a county any area that is the equivalent of a county. Section 6a.103A-1(b)(4)(i) of the Temporary Income Tax Regulations (issued under section 103A of the Internal Revenue Code of 1954, the predecessor of section 143) provides that the term “State” includes a possession of the United States and the District of Columbia.

.07 Section 6a.103A-2(f)(5)(i) provides that an issuer may rely upon the average area purchase price safe harbors published by the Department of the Treasury for the statistical area in which a residence is located. Section 6a.103A-2(f)(5)(i) further provides that an issuer may use an average area purchase price limitation different from the published safe harbor if the issuer has more accurate and comprehensive data for the statistical area.

.08 Section 25(c) permits a state or political subdivision to establish a qualified mortgage credit certificate program. In general, a qualified mortgage credit certificate program is a program under which the issuing authority elects not to issue an amount of private activity bonds that it may otherwise issue during the calendar year under section 146, and in their place, issues mortgage credit certificates to taxpayers in connection with the acquisition of their principal residences. Section 25(a)(1) provides, in general, that the holder of a mortgage credit certificate may claim a federal income tax credit equal to the product of the credit rate specified in the certificate and the interest paid or accrued during the tax year on the remaining principal of the indebtedness incurred to acquire the residence. Section 25(c)(2)(A)(iii)(III) generally provides that residences acquired in connection with the issuance of mortgage credit certificates must meet the purchase price requirements of section 143(e).

.09 Section 143(f) imposes limitations on the income of mortgagors for whom financing may be provided by qualified mortgage bonds. In addition, section 25(c)(2)(A)(iii)(IV) provides that holders of mortgage credit certificates must meet the income requirement of section 143(f). Generally, under sections 143(f)(1) and 25(c)(2)(A)(iii)(IV), the income requirement is met only if all owner-financing under a qualified mortgage bond and all mortgage credit certificates issued under a qualified mortgage credit certificate program are provided to mortgagors whose family income is 115 percent or less of the applicable median family income. Section 143(f)(5), however, generally provides for an upward adjustment to the percentage limitation in high housing cost areas. High housing cost areas are defined in section 143(f)(5)(C) as any statistical area for which the housing cost/income ratio is greater than 1.2.

.10 Under section 143(f)(5)(D), the housing cost/income ratio with respect to any statistical area is determined by dividing (a) the applicable housing price ratio for such area by (b) the ratio that the area median gross income for such area bears to the median gross income for the United States. The applicable housing price ratio is the new housing price ratio (new housing average area purchase price divided by the new housing average purchase price for the United States) or the existing housing price ratio (existing housing average area purchase price divided by the existing housing average purchase price for the United States), whichever results in the housing cost/income ratio being closer to 1.

.11 Average area purchase price safe harbors for each state, the District of Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, the Virgin Islands, and Guam were last published in Rev. Proc. 2006-17, 2006-14 I.R.B. 709.

.12 The nationwide average purchase price limitation was last published in section 4.02 of Rev. Proc. 2006-17. Guidance with respect to the United States and area median gross income figures that are to be used in computing the housing cost/income ratio described in section 143(f)(5) was last published in Rev. Proc. 2006-20, 2006-17 I.R.B. 841.

.13 This revenue procedure uses FHA loan limits for a given statistical area to calculate the average area purchase price safe harbor for that area. FHA sets limits on the dollar value of loans it will insure based on median home prices and conforming loan limits established by the Federal Home Loan Mortgage Corporation. In particular, FHA sets an area’s loan limit at 95 percent of the median home sales price for the area, subject to certain floors and caps measured against conforming loan limits.

.14 To calculate the average area purchase price safe harbors in this revenue procedure, the FHA loan limits are adjusted to take into account the differences between average and median purchase prices. Because FHA loan limits do not differentiate between new and existing residences, this revenue procedure contains a single average area purchase price safe harbor for both new and existing residences in a statistical area. The Treasury Department and the Internal Revenue Service have determined that FHA loan limits provide a reasonable basis for determining average area purchase price safe harbors. If the Treasury Department and the Internal Revenue Service become aware of other sources of average purchase price data, including data that differentiate between new and existing residences, consideration will be given as to whether such data provide a more accurate method for calculating average area purchase price safe harbors.

.15 The average area purchase price safe harbors listed in section 4.01 of this revenue procedure are based on FHA loan limits released January 3, 2007. FHA loan limits are available for statistical areas in each state, the District of Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, the Virgin Islands, and Guam. See section 3.03 of this revenue procedure with respect to FHA loan limits revised after January 3, 2007.

.16 OMB Bulletin No. 03-04, dated and effective June 6, 2003, revised the definitions of the nation’s metropolitan areas and recognized 49 new metropolitan statistical areas. The OMB bulletin no longer includes primary metropolitan statistical areas.

.01 Average area purchase price safe harbors for statistical areas in each state, the District of Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, the Virgin Islands, and Guam are set forth in section 4.01 of this revenue procedure. Average area purchase price safe harbors are provided for single-family and two to four-family residences. For each type of residence, section 4.01 of this revenue procedure contains a single safe harbor that may be used for both new and existing residences. Issuers of qualified mortgage bonds and issuers of mortgage credit certificates may rely on these safe harbors to satisfy the requirements of sections 143(e) and (f). Section 4.01 of this revenue procedure provides safe harbors for MSAs and for certain counties and county equivalents. If no purchase price safe harbor is available for a statistical area, the safe harbor for “ALL OTHER AREAS” may be used for that statistical area (except for Alaska, for which a separate safe harbor is provided for statistical areas not listed).

.02 If a residence is in an MSA, the safe harbor applicable to it is the limitation of that MSA. If an MSA falls in more than one state, the MSA is listed in section 4.01 of this revenue procedure under each state.

.03 If the FHA revises the FHA loan limit for any statistical area after January 3, 2006, an issuer of qualified mortgage bonds or mortgage credit certificates may use the revised FHA loan limit for that statistical area to compute (as provided in the next sentence) a revised average area purchase price safe harbor for the statistical area provided that the issuer maintains records evidencing the revised FHA loan limit. The revised average area purchase price safe harbor for that statistical area is computed by dividing the revised FHA loan limit by .76.

.04 If, pursuant to section 6a.103A-2(f)(5)(i), an issuer uses more accurate and comprehensive data to determine the average area purchase price for a statistical area, the issuer must make separate average area purchase price determinations for new and existing residences. Moreover, when computing the average area purchase price for a statistical area that is an MSA, as defined in OMB Bulletin No. 03-04, the issuer must make the computation for the entire applicable MSA. When computing the average area purchase price for a statistical area that is not an MSA, the issuer must make the computation for the entire statistical area and may not combine statistical areas. Thus, for example, the issuer may not combine two or more counties.

.05 If an issuer receives a ruling permitting it to rely on an average area purchase price limitation that is higher than the applicable safe harbor in this revenue procedure, the issuer may rely on that higher limitation for the purpose of satisfying the requirements of section 143(e) and (f) for bonds sold, and mortgage credit certificates issued, not more than 30 months following the termination date of the 12-month period used by the issuer to compute the limitation.

.06 Section 4.02 of this revenue procedure sets forth a single nationwide average purchase price for purposes of computing the housing cost/income ratio under section 143(f)(5).

.07 Issuers must use the nationwide average purchase price set forth in section 4.02 of this revenue procedure when computing the housing cost/income ratio under section 143(f)(5) regardless of whether they are relying on the average area purchase price safe harbors contained in this revenue procedure or using more accurate and comprehensive data to determine average area purchase prices for new and existing residences for a statistical area that are different from the published safe harbors in this revenue procedure.

.08 If, pursuant to section 6.02 of this revenue procedure, an issuer relies on the average area purchase price safe harbors contained in Rev. Proc. 2006-17, the issuer must use the nationwide average purchase price set forth in section 4.02 of Rev. Proc. 2006-17 in computing the housing cost/income ratio under section 143(f)(5). Likewise, if, pursuant to section 6.05 of this revenue procedure, an issuer relies on the nationwide average purchase price published in Rev. Proc. 2006-17, the issuer may not rely on the average area purchase price safe harbors published in this revenue procedure.

.01 Average area purchase prices for single-family and two to four-family residences in MSAs, and for certain counties and county equivalents are set forth below. The safe harbor for “ALL OTHER AREAS” (found at the end of the table below) may be used for a statistical area that is not listed below.

.02 The nationwide average purchase price (for use in the housing cost/income ratio for new and existing residences) is $269,600.

Rev. Proc. 2006-17 is obsolete except as provided in section 6 of this revenue procedure.

.01 Issuers may rely on this revenue procedure to determine average area purchase price safe harbors for commitments to provide financing or issue mortgage credit certificates that are made, or (if the purchase precedes the commitment) for residences that are purchased, in the period that begins on March 8, 2007, and ends on the date as of which the safe harbors contained in section 4.01 of this revenue procedure are rendered obsolete by a new revenue procedure.

.02 Notwithstanding section 5 of this revenue procedure, issuers may continue to rely on the average area purchase price safe harbors contained in Rev. Proc. 2006-17, with respect to bonds sold, or for mortgage credit certificates issued with respect to bond authority exchanged, before April 7, 2007, if the commitments to provide financing or issue mortgage credit certificates are made on or before May 7, 2007.

.03 Except as provided in section 6.04, issuers must use the nationwide average purchase price limitation contained in this revenue procedure for commitments to provide financing or issue mortgage credit certificates that are made, or (if the purchase precedes the commitment) for residences that are purchased, in the period that begins on March 8, 2007, and ends on the date when the nationwide average purchase price limitation is rendered obsolete by a new revenue procedure.

.04 Notwithstanding sections 5 and 6.03 of this revenue procedure, issuers may continue to rely on the nationwide average purchase price set forth in Rev. Proc. 2006-17 with respect to bonds sold, or for mortgage credit certificates issued with respect to bond authority exchanged, before April 7, 2007, if the commitments to provide financing or issue mortgage credit certificates are made on or before May 7, 2007.

The collection of information contained in this revenue procedure has been reviewed and approved by the Office of Management and Budget in accordance with the Paperwork Reduction Act (44 U.S.C. 3507) under control number 1545-1877.
