Important Notes for EROs
• Don’t send Form 8879 to the IRS unless
requested to do so. Retain the completed
Form 8879 for 3 years from the return due
date or IRS received date, whichever is later.
Form 8879 may be retained electronically in
accordance with the recordkeeping guidelines
in Rev. Proc. 97-22, which is on page 9 of
Internal Revenue Bulletin 1997-13 at
www.irs.gov/pub/irs-irbs/irb97-13.pdf.
• Confirm the identity of the taxpayer(s).
• Complete Part III only if you are filing the
return using the Practitioner PIN method. You
aren’t required to enter the taxpayer’s date of
birth, prior year adjusted gross income, or PIN
in the Authentication Record of the
electronically filed return.
• If you aren’t using the Practitioner PIN
method, enter the taxpayer(s) date of birth
and either the adjusted gross income or the
PIN, or both, from the taxpayer’s prior year
originally filed return in the Authentication
Record of the taxpayer’s electronically filed
return. Don’t use an amount from an
amended return or a math error correction
made by the IRS.
• Enter the taxpayer’s PIN(s) on the input
screen only if the taxpayer has authorized you
to do so. If married filing jointly, it is
acceptable for one spouse to authorize you to
enter his or her PIN, and for the other spouse
to enter his or her own PIN. It isn’t acceptable
for a taxpayer to select or enter the PIN of an
absent spouse.
• Taxpayers must use a PIN to sign their
e-filed individual income tax return
transmitted by an ERO.
• Provide the taxpayer with a copy of the
signed Form 8879 for his or her records upon
request.
• Provide the taxpayer with a corrected copy
of Form 8879 if changes are made to the
return (for example, based on taxpayer
review).
• EROs can sign the form using a rubber
stamp, mechanical device (such as a
signature pen), or computer software
program. See Notice 2007-79, 2007-42 I.R.B.
809, available at www.irs.gov/
irb/2007-42_IRB/ar10.html, for more
