⚠ If something goes wrong
Form 8878-A lets a taxpayer give a signed permission for the electronic return originator to pull the payment owed when filing Form 7004. The form is kept on file and never mailed to the IRS.
The authorized person who signs the electronic funds withdrawal and the electronic return originator (ERO) must complete Form 8878-A.
Part I records the tentative total tax, total payments and credits, and balance due from Form 7004. Part II captures the ERO’s six‑digit EFIN and five‑digit PIN, plus the authorized person’s signature, date, and title. Part III records the authorized person’s PIN and signature confirmation.
Do not send Form 8878-A to the IRS; retain it for your records and give it to the authorized person for signature before transmitting Form 7004.
First, copy the amounts from Form 7004 (lines 6‑8) into Part I. Next, enter the ERO’s six‑digit EFIN and five‑digit PIN in Part II. Then the authorized person signs, dates, and titles the form in Part II and checks the box in Part III to certify the PIN as a signature. Finally, retain the completed form for three years and do not mail it to the IRS.
If the form is incomplete or the PIN is entered incorrectly, the electronic Form 7004 may be rejected and the filer could face penalties for false statements under perjury.
The form states not to send it to the IRS. Verify that the form is kept for records only and not mailed.
The PIN must be five numbers other than all zeros. Confirm the PIN contains non‑zero digits before signing.
