Form 2553 cannot be e-filed directly with the IRS. Fax or mail it.

The Deadline

Form 2553 must be filed within 2 months and 15 days after the beginning of the tax year the election takes effect, or at any time during the preceding tax year. For calendar-year corporations, that means by March 15. Miss this deadline and you'll need to use late election relief under Rev. Proc. 2013-30 (attach the form to a timely filed 1120-S with "FILED PURSUANT TO REV. PROC. 2013-30" written across the top).

What the IRS Sends Back

If accepted: Notice CP 261 arrives by mail in approximately 60 days (up to 5 months if you checked box Q1). CP 261 confirms your S-Corp election and effective date. If denied: Notice CP 264 arrives by mail with the reason for denial. You can re-file immediately. If you lose CP 261, call (800) 829-4933 and request a Letter 385C (S-Corp verification) by fax or mail.

Fax or mail

Fax gives you a timestamped transmission confirmation right away. It does not get the mailing-date protection a postmark gets, and certified mail with return receipt adds proof of mailing at extra cost. Close to the deadline, fax for speed and also send it by certified mail.

Can I e-file Form 2553?

Not directly with the IRS. Form 2553 must be faxed or mailed. For late elections, it can be attached to a timely filed Form 1120-S. The underlying 2553 itself is not electronically filed.

The IRS cannot reissue CP 261. Instead, call (800) 829-4933 and request a Letter 385C (S-Corp verification letter). It can be delivered by fax or mail.
