Quick Facts

Tax‑exempt organizations that file Form 990, 990‑EZ, 990‑PF, or 990‑N are the filers.
The form captures the organization’s name, EIN, tax‑year, the return being extended, and the requested extension end date.
File Form 921 by the original due date of the return (usually the 15th day of the 5th month after the tax year ends).
Mail the completed form to the address listed in the instructions for the organization’s filing location, or fax if the IRS permits electronic submission for that form year.
Late or incomplete extensions cause the original return to be considered late, triggering penalties and interest.

Indicate the requested extension end date (no later than six months after the original due date). 4. Sign and date the form. 5.
