Form 8879 authorizes a tax preparer to electronically file your federal income tax return using a personal identification number (PIN) as your electronic signature. This form is not sent to the IRS — it is kept on file between you and your tax preparer as proof you authorized the e-filing.
Part I: Review the AGI and total tax from your return, which the preparer will have entered.
Verify that the amounts shown match the return you reviewed.
Part II: Enter a self-selected 5-digit PIN (any five numbers except all zeros) as your electronic signature.
If filing jointly, your spouse must also enter their own 5-digit PIN.
Sign and date the form.
Part III is completed by the Electronic Return Originator (ERO) / tax preparer.
