Form 2553, Election by a Small Business Corporation

Eligibility requirements

To make a valid S election the entity must be a domestic corporation (or LLC), have only one class of stock, have no more than 100 shareholders, and have only eligible shareholders — generally individuals, certain trusts and estates, and tax-exempt organizations. Nonresident aliens, partnerships, and most C-corporations cannot be S-corp shareholders.

Filing deadlines

For a brand-new entity, Form 2553 must be filed within 2 months and 15 days after the start of the tax year the election is to take effect. For an existing entity, the form must be filed by March 15 of the year the election is to apply (calendar year) or the equivalent date for fiscal-year filers.

Late election relief

If you missed the deadline, Revenue Procedure 2013-30 allows automatic late election relief in many cases. The form must include the language "FILED PURSUANT TO REV. PROC. 2013-30" and explain the reasonable cause for late filing. Most missed S elections can be cured under this procedure within 3 years and 75 days.

Shareholder consents

All shareholders on the date of election must sign Form 2553. A spouse who has a community property interest in the stock must also sign, even if not listed on the stock ledger. Missing consents are the single most common reason an S election is rejected by the IRS.

Coordination with state

Some states automatically follow the federal S election; others (notably New York and New Jersey) require a separate state-level election. Confirm your state's rules to avoid an unexpected state-level corporate income tax bill.

What it does not cover

Form 2553, Election by a Small Business Corporation does not stand alone — it lives inside a small ecosystem of supporting forms, schedules, and elections that together carry the full weight of a small-business return. Knowing what Form 2553, Election by a Small Business Corporation does not handle is just as important as knowing what it does. The instructions list the cross-references explicitly: items computed elsewhere (Schedule C net profit, Schedule SE self-employment tax, Form 4562 depreciation), items reported on a separate form (Form 8829 home office, Form 1099-NEC information returns), and items handled by an entirely different return entirely (Form 1120-S for S-corps, Form 1065 for partnerships). Drawing the boundary cleanly avoids double-counting and avoids leaving deductions on the table.
