What Is IRS Form 2553?
Form 2553 is the election form used by a domestic corporation (or eligible entity treated as a corporation) to choose S corporation status under Internal Revenue Code Section 1362(a). Once approved, the business’s income, losses, deductions, and credits pass through to shareholders, who report them on their personal tax returns (Form 1040) at individual rates.
An S corporation generally does not pay federal income tax at the entity level (except on built-in gains or passive investment income in some cases). This avoids the double taxation that C corporations face.
Note: Eligible entities (like LLCs) do not need a separate Form 8832 entity classification election if they timely file Form 2553 and meet all S corp tests.
Who Can File Form 2553? S Corporation Eligibility Requirements
To qualify under IRS Instruction 2553, the entity must meet all of these tests (per IRC Sections 1361 and 1362):
- It is a domestic corporation (or domestic eligible entity).
- It has no more than 100 shareholders (spouses and certain family members can count as one; see family attribution rules in Section 1361(c)(1)).
- Shareholders are limited to individuals, estates, certain trusts (QSST or ESBT), or tax-exempt organizations under 401(a) or 501(c)(3). No partnerships, corporations, or nonresident aliens (except as potential beneficiaries of an ESBT).
- It has only one class of stock (differences in voting rights are allowed, but distribution and liquidation rights must be identical).
- It is not an ineligible corporation (e.g., certain banks using reserve method, insurance companies taxed under Subchapter L, or former DISC).
The corporation must also adopt a permitted tax year (usually calendar year, or one with business purpose approval).
Pro Tip: Review the full “Who May Elect” section in the official IRS Instruction 2553 for details on trusts, family rules, and one-class-of-stock regulations.
Key Benefits of S Corporation Election
- Pass-through taxation (no corporate-level tax on ordinary income).
- Potential self-employment tax savings (only wages are subject to FICA; distributions are not).
- Ability to deduct health insurance premiums and use other shareholder-employee perks.
- Retained C corp benefits like easier ownership transfers in some cases.
When to File Form 2553: Deadlines & Effective Dates
File no later than 2 months and 15 days after the beginning of the tax year the election is to take effect, or anytime during the prior tax year.
Examples from IRS Instruction 2553:
- New calendar-year entity starts Jan. 7 → File between Jan. 7 and March 21 for first-year effectiveness.
- Existing C corp wants S status for Jan. 1, 2026 → File anytime in 2025 up to March 15, 2026.
- Short-year entity starts Nov. 8 → File by Jan. 22 of the following year.
Item E on the form is critical: For new entities, use the earliest date the business had shareholders, assets, or began operations.
Caution: Filing late usually delays effectiveness to the following tax year unless late-election relief applies.
Step-by-Step: How to Complete Form 2553 (Per IRS Instructions)?
Form 2553 has four parts. Most filers only need Part I.
Part I – Election Information
- Name, Address, EIN (Item A): Use the exact legal name and EIN. If no EIN yet, apply at IRS.gov/EIN and write “Applied For.”
- Date Incorporated & State (Items B–C).
- Name/Address Change (Item D): Check if applicable.
- Effective Date (Item E): Critical for timing.
- Tax Year (Item F): Usually calendar year (box 1). Complete Part II for fiscal or 52-53-week years.

- Late Election Statement (Item I): Explain reasonable cause if late (attach details).
- Shareholder Table (Columns J–N):
- List every current and (if applicable) former shareholder who owned stock during the relevant period.

- Number of shares or ownership % and dates acquired.
- SSN/EIN and shareholder tax year end.
Signature: An authorized corporate officer (president, treasurer, etc.) must sign the form.
Part II – Tax Year (if applicable)
Required if requesting a fiscal year or Section 444 election. Attach supporting statements and possibly pay a user fee for business-purpose approval.
Part III – QSST Election (if applicable)

For entities that also missed a Form 8832 filing.
