Quick Facts

The executor, personal representative, or fiduciary of a decedent’s estate files this form.
The form captures the decedent’s date of death, the estate’s EIN, the requested extension period, and the reason for the request.
File Form 9210 before the original estate tax return due date (generally 9 months after death). The extension must be filed by that deadline to be effective.
Mail the completed form to the address listed in the Form 9210 instructions for the appropriate IRS processing center, or submit electronically if the estate uses approved e‑file software.
An untimely estate tax return can trigger penalties and interest; an approved extension protects the estate from those charges while work continues.
1. Gather the estate’s EIN, decedent’s death certificate, and a clear reason for the delay. 2. Complete the top section with identifying information. 3. Indicate the requested extension end date (up to six months). 4. Sign and date the form as the personal representative. 5. Mail or e‑file before the original filing deadline.
