Fillable Form 8879 Online in 2026

IRS Form 8879 is a signature authorization for certain federal tax returns filed online by an electronic return originator, or ERO. An ERO is often a tax professional who prepares and sends your return to the IRS. The form covers Forms 1040, 1040-SR, 1040-NR, 1040-SS, and 1040-X.

By signing Form 8879, you confirm that you reviewed the return and authorize the ERO to enter your five-digit personal identification number, or PIN, as your signature. You must sign it before the ERO files your return. The ERO keeps the signed form and provides it to the IRS only if requested. Form 8879 is not your tax return and does not replace Form 1040 or another covered return.

You may receive IRS Form 8879 when an electronic return originator (ERO), such as a tax preparer, plans to e-file your individual income tax return using the Practitioner PIN method. By signing it, you authorize the ERO to enter or generate your personal identification number as your electronic signature.

The form also confirms that you reviewed the return and believe it is accurate before filing. If your return includes an electronic withdrawal to pay tax, your signature authorizes the Treasury Department to debit the listed financial account.

The Internal Revenue Service (IRS), a bureau of the U.S. Department of the Treasury, issues Form 8879. You can find the official IRS Form 8879 PDF on the IRS website.

PDFLeader has a blank version pre-loaded in our browser-based editor, so you do not need to download a template from another source. You can fill out the form and download the completed copy for future use. PDFLeader does not file or submit Form 8879 to the IRS.

After you download and sign Form 8879, return it to your electronic return originator (ERO), usually your tax preparer. You may give it to the ERO in person or return it by mail, private delivery service, email, fax, or the preparer’s website or portal, based on the options the ERO accepts.

Do not mail Form 8879 to the IRS or include it with your tax return. The ERO keeps the signed form in its records. A copy goes to an IRS office only if the IRS later asks the ERO for it.

You and your electronic return originator (ERO), often a tax professional, must complete Form 8879. Each taxpayer must check the accuracy of the income tax return and either authorize the ERO to create or enter a PIN or use their own PIN. For a joint return, both spouses must provide authorization. The ERO completes the required sections when using the Practitioner PIN method or entering the taxpayer’s PIN.

Afterward, the ERO keeps the signed Form 8879 as proof of your authorization for that tax year. The ERO also gives you a copy of the completed return and related electronic filing records. You and the ERO should retain copies for IRS recordkeeping or an audit. Do not send the form to the IRS unless the agency asks for it.

You can add a simple electronic signature to Form 8879 on our platform, then download the completed form. A typed name alone does not meet the IRS e-signature process for ERO software, which includes identity checks and records certain taxpayer details. You may sign by hand after downloading instead. Check the latest IRS updates and your ERO’s instructions, then return the form outside PDFLeader, since our platform does not submit or file it.

Have the completed Form 1040 available before completing Form 8879. You need the taxpayer’s name and SSN or ITIN. For a joint return, you also need the spouse’s name and SSN or ITIN. Part I, Tax Return Information, contains dollar amounts imported from Form 1040, such as total income, total tax, refund, or amount owed.

In Part II, review the Taxpayer Declaration and Signature Authorization statements. Check the box that lets the ERO enter or generate your five-digit PIN, or the box stating that you will enter your own PIN under the Practitioner PIN method. Then provide the taxpayer’s signature and date. A spouse must also sign and date a joint return. If using the Practitioner PIN method, the ERO completes Part III with the ERO’s EFIN/PIN, signature, and date.

Form 8879 has no fixed IRS filing deadline because it is not sent to the IRS. You must sign and date it before the electronic return originator (ERO) transmits your return. Your signature authorizes the ERO to originate the electronic submission.

The ERO must keep Form 8879 for three years from the return’s due date or the date the IRS receives the return, whichever is later. This retention period applies to the ERO, not as a separate filing deadline for you.

Form 8879 is not required when you prepare and electronically file your own return. It is also not required when the Practitioner PIN method is not used and you personally enter your PIN on the electronic return originator’s system. In that case, the electronic record must include the authentication required by IRS rules.

There is no income or tax amount that removes the requirement. If a return cannot use an electronic signature, the filing process may require Form 8453 instead. Form 8453 is not a general substitute for Form 8879.
