Rejects come from IRS Modernized e-File (MeF) when a return fails validation. The reject code has two parts — the schema family (R0000, IND, F1040, FW2, etc.) and the specific reject reason. Most rejects can be fixed by correcting the data and re-transmitting; the IRS treats the re-filed return as timely if the original was transmitted by the deadline AND it's accepted within 5 calendar days of the reject (per Pub 4163). If you cannot fix the reject before the 5-day grace period, paper-file the return and attach Form 8948 (Preparer Explanation for Not Filing Electronically). For identity-related rejects (R0000-500/503/504, IND-901), assume potential identity theft and file Form 14039 if confirmed.
