The Self-Select PIN Method ( Personal Identification Number ) is one option for taxpayers to use when signing their electronic Form 1040 and Form 4868. The PIN is any five numbers (except all zeros) the taxpayer chooses to enter as their electronic signature. Taxpayers are required to use a PIN when they file an electronic tax return using an Electronic Return Originator (ERO) or commercial-off-the-shelf (COTS) tax preparation software.

Most taxpayers are eligible to use the Self-Select PIN Method. To do so, taxpayers must provide their date of birth and Adjusted Gross Income (AGI) amount or the Self-Select PIN from the original prior year tax return so the IRS can authenticate them. Click the IRS.gov web page link Validate Your Identity After Signing Your Electronic Tax Return for more information.

If the taxpayer agrees, it is acceptable for an ERO and/or software program to generate or assign the taxpayer PIN. The taxpayer consents to the ERO's choice by completing and signing an IRS e-file signature authorization containing the intended taxpayer PIN. The taxpayer PIN can be systemically generated or manually assigned into the electronic format and/or the signature authorization form. However, the ERO must receive the signature authorization signed by taxpayers before they transmit the return or release it for transmission to the IRS.

How can the taxpayer get their prior year original AGI or prior year PIN if they did not bring in last year's tax return or they are a new client?

There are several ways to find your prior year AGI.

Preferred method

You should always retain a copy of your tax return.

  • On your 2015 tax return, your AGI is on line 37 of the Form 1040; line 21 on the Form 1040-A or line 4 on the Form 1040-EZ.
  • If you used a paid preparer last year, you might obtain a copy of last year's tax return from that preparer.
  • If you are using the same tax preparation software that you used last year, that software will likely have your prior year tax return for you to success.
  • If you are not using the same tax preparation software as last year, you may be able to return to your prior-year software and view an electronic copy of your prior-year.

Alternative methods

If you do not have a copy of your prior year tax return, you may use a Get Transcript self-help tool to get a Tax Return Transcript showing your AGI.

  • Use Get Transcript Online to immediately view your AGI. You must pass the Secure Access identity verification process. Select the Tax Return Transcript and use only the "Adjusted Gross Income" line entry.
  • Use Get Transcript by Mail or call 800-908-9946 if you cannot pass Secure Access and need to request a Tax Return Transcript. Please allow 5 to 10 days for delivery. Use only the "Adjusted Gross Income' line entry.
  • If you have been issued an Identity Protection (IP) PIN (via a CP01A), you should enter it when prompted by your software. It will serve to verify your identity.

If the taxpayer has never filed a tax return or did not need to file a prior year tax return, what amount do they enter for the prior year original AGI or prior year PIN?

Enter zero ("0") for the original AGI. Do not leave this field blank. The return will reject if the field is left blank for a zero amount. However, the prior year PIN field should be left blank.

If the taxpayer changed filing status from their prior tax return, what adjusted gross income (AGI) or PIN should be used?

If the change is to Married Filing Jointly, then each taxpayer will use their individual original total Adjusted Gross Income amount or PIN from their respective prior year tax returns.

If the change is from Married Filing Jointly, then each taxpayer will use the same original total Adjusted Gross Income amount or PIN from their prior year joint return.

If my client had an ITIN (individual taxpayer identification number) when they filed their prior year tax return, but now has a SSN for the current filing season, what prior year AGI amount do they use?

If your client had an ITIN when they filed their prior year tax return, but now has a SSN to file their current year tax return, they should use Zero (0) as the prior year AGI amount.

What AGI amount should be used for a taxpayer that filed jointly with a different spouse in the prior tax year?

Use the AGI amount or PIN from the joint return filed with the ex-spouse.

What AGI amount should be used when one taxpayer of the joint return earned all the wages?

Both taxpayers on the joint return will use the total AGI amount from the originally filed return. The AGI amount should not be divided between the primary and the spouse.

If my client filed an amended prior year tax return, what AGI amount or PIN should they use?

Your client must use the original AGI amount or PIN from the originally filed return. The return will reject if the amended AGI amount is used. Do not use amounts from an amended return, a corrected amount from a math error notice, or a changed amount from IRS.

If my client filed their prior year tax return after April 15, what AGI amount should they use?

If your client's prior year tax return was not received and processed by IRS by December 7 of the current tax year, they must enter "0" (zero) for the AGI amount. If the return is rejected due to mismatch of the AGI, resubmit the return using the actual values.

If my client's prior year return is negative what should they use?

If your client's prior year tax return AGI is negative they need to enter the AGI as a negative amount.

Why is a date of birth required with the self-select PIN method?

The Date of Birth is required as part of the authentication process for the taxpayer. It will be matched against Social Security Records. The return will not be rejected if the Date of Birth does not match. However, the Acknowledgement Record will contain the field Date of Birth Validity Code. It will advise you if the dates of birth submitted were valid or mismatched. The following values will be returned:

  • "0" = Date of Birth Validation Not Required
  • "1" = All Dates of Birth Valid
  • "2" = Primary Date of Birth Mismatch
  • "3" = Spouse Date of Birth Mismatch
  • "4" = Both Dates of Birth Mismatch

Electronic signature (PIN) methods

How is the return signed if my client does not want to enter a PIN?

All e-file individual returns submitted to the IRS by tax practitioners must be electronically signed using a PIN. The Practitioner PIN method can be used to obtain the taxpayer's signature on Form 8879; this authorizes the Electronic Return Originator (ERO) to generate or enter the taxpayer's PIN on the electronically filed return.

If the taxpayer uses a PIN and owes taxes, can they pay the balance due electronically?

Yes. Taxpayers who use a PIN may pay their balance due by electronic funds withdrawal or credit card.

Are all taxpayers who file electronically and sign with a PIN required to pay any balance due electronically?

No. Taxpayers who prefer to pay by check or money order should file Form 1040-V, Payment Voucher. Form 8879, IRS e-file Signature Authorization, should not be used to transmit any payments.

Is the self-select PIN a universal PIN?

No. It is used as the taxpayer's electronic signature on their Individual Income Tax Return only. However, taxpayers may also use it as a piece of authentication when signing the next year's tax return using electronic signature.

Can the taxpayer use the same PIN to sign their return next year?

Yes, or they may choose any 5 digits except all zeros.

What happens if two taxpayers select and use the same PIN to sign their return/document?

It is acceptable for two taxpayers to choose the same five digit PIN. The taxpayer's personal information (Social Security Number, Date of Birth and original Adjusted Gross Income or PIN from the prior year tax return) provided to the IRS is used to verify the taxpayer's identity.

What is the prior year PIN?

The Prior Year PIN is the PIN the taxpayer used to sign their previous year tax return.

How would my client get a copy of their prior year pin?

EROs will need to provide taxpayers with documentation that has the PIN on it. Tax Preparation software should be capable of providing the taxpayer with a copy of the PIN used in their current tax return so that it will be available for them to use as an authenticator next year. As a suggestion, the PIN can be preprinted on the signature line of the tax return to avoid additional paper generation.

What PIN does the taxpayer use when the prior year return was originally rejected and the corrected return/document was retransmitted with a different PIN?

The PIN that was entered on the e-file accepted tax return/document is the PIN the taxpayer must use to authenticate themselves.

Do both taxpayers filing a joint return need a PIN?

Yes, each taxpayer must sign using a PIN. The taxpayers will choose any five digits, except all zeros, as the electronic signatures.

Can the taxpayer electronically file a joint return if the spouse is unable to sign because he or she is serving in a combat zone, or a qualified hazardous duty area, and the taxpayer does not have a power of attorney or other statement?

Yes, a joint return can be electronically filed without the spouse's electronic PIN signature if the spouse is unable to sign because he or she is serving in a combat zone or a qualified hazardous duty area, and the taxpayer does not have a power of attorney or other statement.

What is an ERO PIN?

The ERO PIN is the ERO's electronic signature. For consistency, each ERO is encouraged to use the same 11 numbers for their ERO PIN on all returns for this filing season. The first 6 positions of your ERO PIN must be your EFIN and it must match the EFIN in the Submission ID. You may select any 5 digits except all zeros for the next five positions. It does not take place of the taxpayer's PIN. A taxpayer PIN is also required.

How do I know the IRS received the taxpayer's PIN?

When you receive your Acknowledgement Record, all accepted returns will have the PIN Presence Indicator. The following values will be returned:

  • "Practitioner PIN"
  • "Self-Select PIN" by Practitioner Used
  • "Online Filer PIN"

For rejected returns, this value will not be present.

Will the ERO PIN be validated?

If the ERO PIN is not present, the return will reject displaying an error reject code.

Where can I receive a copy of the MeF business rules (error codes) for the self-select PIN method?

Staring TY2016/PY2017 Modernized e-File (MeF) schemas and business rules for all form families will no longer be available through IRS.gov and will be delivered with a more secure and controlled process. Distribution will be through the Registered User Portal - eServices Secure Object Repository (SOR) for delivery to the software providers starting in mid-August. Software providers will sue their existing eServices account to pick up the schema and business rules packages. The IRS will send Quick Alerts messages letting users know that the schema and business rule packages are in their SOR accounts and ready for pick-up. The IRS understands the importance of getting the schemas and business rules distributed to the Software community as soon as they are ready so we will be using a manual process through the MeF mailbox until the automated solution is available.

Please contact the MeF Mailbox with the Company Name, your Authorized User role, ETIN, and Schema package(s) you would like to receive or if you have any questions.

If my client uses the Self-Select PIN method to sign their return, how is an election for certain tax treatment, status, exception or exemption based on an instruction for the tax form or in a related tax publication submitted?

If your client uses the Self-Select PIN method to sign their return, an is making an election for certain tax treatment, status, exception or exemption based on an instruction for the tax form or in a related tax publication, the General Dependency Medium must be used if there is no official form or XML schema designed for the election. Practitioners should not attach a copy of the election to the Form 8453, U.S. Individual Income Tax Transmittal for an IRS e-file Return.
