Form 2553 S-Corp Election

Form 2553 elects S-corp tax treatment. Missing the 75-day window isn't fatal, Rev. Proc. 2013-30 allows late relief in most cases.

Filing window

Form 2553 must be filed by the 15th day of the third month of the tax year you want the election to take effect (March 15 for a calendar-year business).

Late election relief

Rev. Proc. 2013-30 allows late S-elections up to 3 years and 75 days past the due date if you can demonstrate reasonable cause and intent to be treated as an S-corp all along. We file the relief language on 2553.

Call the office and a human answers.

Common questions

When should I file Form 2553?
Ideally immediately after entity formation. You can elect retroactively to January 1 of the current year if the election is filed by March 15.
