Part II Declaration and Signature Authorization of Fiduciary (Be sure to get a copy of the estate’s or 

trust’s return)

Under penalties of perjury, I declare that I am a fiduciary of the above estate or trust and that I have examined a copy of the estate’s or trust’s 

2010 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 estate’s or trust’s 

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

estate’s or trust’s return to the IRS and to receive from the IRS (a) an acknowledgment 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 estate’s or trust’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 estate’s or trust’s electronic income tax return and, if applicable, the estate’s or trust’s 

consent to electronic funds withdrawal.

Purpose of Form

A fiduciary and an ERO use Form 8879-F 

when the fiduciary wants to use a 

personal identification number (PIN) to 

electronically sign an estate’s or trust’s 

electronic income tax return and, if 

applicable, consent to electronic funds 

withdrawal. A fiduciary who does not use 

Form 8879-F must use Form 8453-F, 

U.S. Estate or Trust Income Tax 

Declaration and Signature for Electronic 

Filing. For more information, see the 

instructions for Form 8453-F.

Do not send this form to the IRS. 

The ERO must retain Form 8879-F.

ERO Responsibilities

The ERO will:

• Enter the name and employer 

identification number of the estate or 

trust at the top of the form;

• Complete Part I using the amounts 

(zero may be entered when appropriate) 

from the estate’s or trust’s 2010 income 

tax return;

• Enter on the authorization line in Part II 

the ERO firm name (not the name of the 

individual preparing the return) if the 

ERO is authorized to enter the officer’s 

PIN;

• Give the fiduciary Form 8879-F for 

completion and review—this can be 

done by hand delivery, U.S. mail, private 

delivery service, email, or Internet 

website; and

• Complete Part III, including a signature 

and date.

▲!

CAUTION

You must receive the 

completed and signed Form 

8879-F from the fiduciary 

before the electronic return 

is transmitted (or released for 

transmission).

Fiduciary Responsibilities

The fiduciary will:

• Verify the accuracy of the estate’s or 

trust’s prepared income tax return;

• Check the appropriate box in Part II to 

either authorize the ERO to enter the 

fiduciary’s PIN or choose to enter it in 

person;

• Indicate or verify his or her PIN when 

authorizing the ERO to enter it (the PIN 

must be five numbers other than all 

zeros);

• Sign and date Part II; and

• Return the completed Form 8879-F to 

the ERO by hand delivery, U.S. mail, 

private delivery service, or fax.

The estate’s or trust’s return will not 

be transmitted to the IRS until the ERO 

receives the fiduciary’s signed Form 

8879-F.

Important Notes for EROs

• Do not send Form 8879-F to the IRS 

unless requested to do so. Retain the 

completed Form 8879-F for 3 years from 

the return due date or IRS received date, 

whichever is later. Form 8879-F can be 

retained electronically in accordance 

with the recordkeeping guidelines in Rev.
