E-file (EFIN, ERO, Form 8879) and preparer penalties

Preparers who expect to file 11 or more individual returns a year must e-file through an EFIN-holding ERO, get the client's signature on Form 8879 (kept 3 years), notify clients of rejects within 24 hours, and face per-failure penalties under IRC 6694 and 6695 for unreasonable positions, missing signatures, PTINs, copies and due diligence.

Worked example

Facts: A preparer files 300 returns. One client insists on paper; another return claims EITC and HOH but the preparer skipped Form 8867.

Consequences: Paper return: attach Form 8948 (taxpayer choice) and keep the client’s signed statement. Missing due diligence: $650 for EITC + $650 for HOH = $1,300 under IRC 6695(g) (plus CTC/AOTC if claimed). Form 8879s for all e-filed returns are kept 3 years.

Exam traps

  • The threshold is 11 or more returns, not 10.
  • Form 8879 is not sent to the IRS unless requested.
  • Due diligence penalties are per credit/status per return, with no annual cap.
  • Acceptance of an e-filed return is not approval of its contents.

Frequently asked questions

How long must an ERO keep Form 8879?

3 years from the return due date or the IRS received date, whichever is later.

What happens if an e-filed return is rejected?

The ERO must tell the taxpayer within 24 hours and either fix and retransmit (within 5 days to keep the original date, if rejected at the deadline) or advise paper filing (within 10 days with an explanation).
