Form 8879‑F – Fillable IRS E‑File Signature Authorization

Form 8879‑F, IRS E‑File Signature Authorization for Form 1041, is used by fiduciaries of estates and trusts to give their tax professional permission to electronically sign and file the income‑tax return (Form 1041). This one‑page, fillable PDF lets you securely provide the required information without printing or scanning.

What Is Form 8879‑F?

The form consists of three parts:

• Part I – Tax Return Information: Copies key figures from the 1041 (total income, taxable income, tax due, etc.).
• Part II – Declaration and Signature Authorization: The fiduciary declares under penalty of perjury that the return is true and authorizes the electronic return originator (ERO) to sign.
• Part III – Certification and Authorization: The tax professional certifies that the return was reviewed and that the fiduciary’s PIN is correct.

Common Mistakes & Tips for Fiduciaries

Being a fiduciary carries legal responsibility. Avoid these pitfalls:

• Enter the exact Fiscal Year dates – a mismatch will cause the IRS to reject the filing.
• Double‑check the EIN and trust name; typos trigger processing delays.
• Use a five‑digit PIN that you can remember but is not easily guessable.
• Sign the form only after you have reviewed the entire Form 1041 for accuracy.

Where to Submit the Completed Form

After you finish the fillable form, you can:

• Save a PDF copy for your records.
• Send the signed PDF to your tax preparer – they will upload it with the electronic return.
• Retain the form for at least three years in case the IRS requests it.

Remember, the IRS only requires the form when the ERO specifically asks for it. Otherwise, keep it on file.
