Part II Taxpayer Declaration and Signature Authorization (Be sure you get and keep a copy of your return)

Under penalties of perjury, I declare that I have examined a copy of my electronic individual income tax return and accompanying schedules and statements 

for the tax year ending December 31, 2017, and to the best of my knowledge and belief, it is true, correct, and accurately lists all amounts and sources of income 

I received during the tax year. I further declare that the amounts in Part I above are the amounts from my electronic income tax return. I consent to allow my 

intermediate service provider, transmitter, or electronic return originator (ERO) to send my return to the IRS and to receive from the IRS (a) an acknowledgement 

of receipt or reason for rejection of the transmission, (b) the reason for any delay in processing the return or refund, and (c) the date of any refund. If applicable, I 

authorize the U.S. Treasury and its designated Financial Agent to initiate an ACH electronic funds withdrawal (direct debit) entry to the financial institution 

account indicated in the tax preparation software for payment of my federal taxes owed on this return and/or a payment of estimated tax, and the financial 

institution to debit the entry to this account. This authorization is to remain in full force and effect until I notify the U.S. Treasury Financial Agent to terminate the 

authorization. To revoke (cancel) a payment, I must contact the U.S. Treasury Financial Agent at 1-888-353-4537. Payment cancellation requests must be 

received no later than 2 business days prior to the payment (settlement) date. I also authorize the financial institutions involved in the processing of the electronic 

payment of taxes to receive confidential information necessary to answer inquiries and resolve issues related to the payment. I further acknowledge that the 

personal identification number (PIN) below is my signature for my electronic income tax return and, if applicable, my Electronic Funds Withdrawal Consent.

To check the status of your 2017 refund, do 

one of the following.

• Go to IRS.gov and click on Where’s My 

Refund.

• Call 1-800-829-4477 for automated refund 

information and follow the recorded 

instructions.

• Call 1-800-829-1954.

Important Notes for EROs

• Don’t send Form 8879 to the IRS unless 

requested to do so. Retain the completed 

Form 8879 for 3 years from the return due 

date or IRS received date, whichever is later. 

Form 8879 may be retained electronically in 

accordance with the recordkeeping guidelines 

in Rev. Proc. 97-22, which is on page 9 of 

Internal Revenue Bulletin 1997-13 at 

www.irs.gov/pub/irs-irbs/irb97-13.pdf.

• Confirm the identity of the taxpayer(s). 

• Complete Part III only if you are filing the 

return using the Practitioner PIN method. You 

aren’t required to enter the taxpayer’s date of 

birth, prior year adjusted gross income, or PIN 

in the Authentication Record of the 

electronically filed return.

• If you aren’t using the Practitioner PIN 

method, enter the taxpayer(s) date of birth 

and either the adjusted gross income or the 

PIN, or both, from the taxpayer’s prior year 

originally filed return in the Authentication 

Record of the taxpayer’s electronically filed 

return. Don’t use an amount from an 

amended return or a math error correction 

made by the IRS.

• Enter the taxpayer’s PIN(s) on the input 

screen only if the taxpayer has authorized you 

to do so. If married filing jointly, it is 

acceptable for one spouse to authorize you to 

enter his or her PIN, and for the other spouse 

to enter his or her own PIN. It isn’t acceptable 

for a taxpayer to select or enter the PIN of an 

absent spouse.

• Taxpayers must use a PIN to sign their 

e-filed individual income tax return 

transmitted by an ERO.

• Provide the taxpayer with a copy of the 

signed Form 8879 for his or her records upon 

request.

• Provide the taxpayer with a corrected copy 

of Form 8879 if changes are made to the 

return (for example, based on taxpayer 

review).

• EROs can sign the form using a rubber 

stamp, mechanical device (such as a 

signature pen), or computer software 

program. See Notice 2007-79, 2007-42 I.R.B. 

809, available at 

www.irs.gov/irb/2007-42_IRB/ar10.html for
