What Form 8879 is and when it’s used

Form 8879, IRS e-file Signature Authorization, is a one-page document used to authorize an electronic return originator (ERO) to file an individual income tax return electronically. The taxpayer (and spouse, if applicable) signs to permit the preparer to enter a Personal Identification Number (PIN) on their Form 1040 series return and confirms the accuracy of the return information before e-filing with the IRS.

Why completing Form 8879 matters

Form 8879 creates a recorded, signed authorization for electronic filing, documents taxpayer consent for a preparer-entered PIN, and forms part of the return’s compliance record with the IRS. It helps reduce paper handling, speeds submission, and provides an auditable signature trail for both preparers and filers.

Why completing Form 8879 matters

Who typically completes and keeps Form 8879

The form is used by taxpayers and by paid preparers who file returns electronically on behalf of clients.

  • Individual taxpayers — sign to authorize e-file and confirm return accuracy.
  • Tax preparers / CPAs — retain the signed authorization per IRS recordkeeping rules.
  • Payroll or HR teams — use when filing employee-related individual returns or adjustments.

Copies of the signed Form 8879 are retained by the preparer and provided to the taxpayer as evidence of consent and authorization.
