Important Notes for EROs

• Do not send Form 8878 to the IRS unless 

requested to do so. Retain the completed 

Form 8878 for 3 years from the return due 

date or the date the IRS received the 

return, whichever is later. Form 8878 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.

• You should confirm the identity of the 

taxpayer(s). 

• Provide the taxpayer with a copy of the 

signed Form 8878 for his or her records 

upon request.

• Provide the taxpayer with a corrected 

copy of Form 8878 if changes are made to 

the extension form (for example, based on 

taxpayer review).

• 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 the 

ERO to enter his or her PIN, and for the 

other spouse to enter his or her own PIN. It 

is not acceptable for a taxpayer to select or 

enter the PIN of an absent spouse.

• If the taxpayer is making a payment by 

electronic funds withdrawal for Form 4868 

and the ERO is not using the Practitioner 

PIN method, the ERO must enter the 

taxpayer’s date of birth and either the 

adjusted gross income amount or the PIN, 

or both, from the taxpayer’s originally filed 

prior year tax return. This information is 

entered when the return is prepared, and is 

used by the IRS to authenticate the 

taxpayer. Do not use an amount from an 

amended return or a math error correction 

made by the IRS.

• Complete Part III only if you are filing 

Form 4868 using the Practitioner PIN 

method.

• 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
