Quick Facts

The personal representative (executor, administrator, or fiduciary) of the decedent’s estate files it.
It captures the estate’s name, taxpayer identification number, date of death, original filing deadline, and the requested extension period.
File before the original 1041 due date, typically April 15 or the 15th day of the 5th month after the year of death, whichever applies.
Mail the completed form to the IRS Service Center listed in the instructions, or fax if an authorized fax number is provided for the specific jurisdiction.
Errors can cause the extension to be denied, resulting in late‑filing penalties and interest on any tax due.
1. Gather the estate’s EIN, decedent’s death certificate, and original 1041 deadline. 2. Complete the top‑section fields on Form 12203‑SP. 3. Sign and date the form as the personal representative. 4. Attach a copy of the death certificate if required. 5. Mail or fax to the address in the instructions before the deadline.
