Part II Declaration and Signature Authorization of Officer (Be sure to get a copy of the corporation’s return)

Under penalties of perjury, I declare that I am an officer of the above corporation and that I have examined a copy of the corporation’s 

2016 electronic income tax return and accompanying schedules and statements and to the best of my knowledge and belief, it is true, 

correct, and complete. I further declare that the amounts in Part I above are the amounts shown on the copy of the corporation’s 

electronic income tax return. I consent to allow my electronic return originator (ERO), transmitter, or intermediate service provider to 

send the corporation’s 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 electronic funds withdrawal (direct debit) entry to the financial 

institution account indicated in the tax preparation software for payment of the corporation’s federal taxes owed on this return, and 

the financial institution to debit the entry to this account. To revoke a payment, I must contact the U.S. Treasury Financial Agent at 

1-888-353-4537 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 have selected a personal identification number (PIN) as my signature for the corporation’s 

electronic income tax return and, if applicable, the corporation’s consent to electronic funds withdrawal.

a personal identification number (PIN) to 

electronically sign a corporation’s

• Check the appropriate box in Part II to 

either authorize the ERO to enter the

Part II; and

the ERO. The acceptable delivery

transmitted to the IRS until the ERO 

receives the officer’s signed Form 

8879-I.
