Key Takeaways

• Form 2553 is the official S corp election form. Filing is free (fee: $0)
• Existing businesses must file by March 15; new businesses have 75 days from incorporation
• You cannot e-file Form 2553. It can only be sent by mail or fax
• Missing the deadline? You may qualify for late S corp election relief under Rev. Proc. 2013-30
• Once elected, S corp status lets you pay self-employment tax only on your salary, not all business income

What Is Form 2553?

IRS Form 2553, "Election by a Small Business Corporation," is the form you file with the Internal Revenue Service to elect S corporation status under Subchapter S. An S corporation is a pass-through entity. Income flows to shareholders' tax returns, avoiding the double taxation that C corporations face.

This S corp election form differs from Form 8832, which changes the general tax class. Filing Form 2553 elects S corp tax status only. After approval, the S corp files Form 1120-S each year and gives each shareholder a Schedule K-1.

Who Can File IRS Form 2553?

Corporations and LLCs in the United States can file IRS Form 2553 if they meet these rules:

• Domestic entity
• 100 or fewer shareholders
• Only individuals or eligible trusts
• All U.S. citizens or residents
• One class of stock
• Not a bank or insurer

Every shareholder must provide shareholder consent by signing the form.

Sole proprietors must first register as an LLC with the Secretary of State or file articles of incorporation. Skipping Form 2553 can cause the IRS to default you to C corporation status, resulting in double taxation on profits.

How To Fill Out Form 2553 Step by Step

To fill out Form 2553, start with Part I. Enter your business name, address, Employer Identification Number (EIN), and incorporation date. Add the effective date of your S corp election (usually 01/01/[year]). Check Box F(1) for a calendar year. All shareholders must sign column K. Parts II, III, and IV apply to non-calendar fiscal years, Qualified Subchapter S Trust situations, and late filers.

Form 2553 Example Fields

For a standard LLC-to-S-corp election, here is how to complete Part I:

• Line A (EIN): 12-3456789
• Line E (effective date): 01/01/2026
• Line F: Box (1) checked: Calendar year
• Line J/K: Shareholder names, ownership %, and signatures.

Common mistakes include:

• Unsigned Line K
• Wrong Line E date
• Forgetting Form 8832 first

The instructions Form 2553 provides on page one cover Part I, which is all most calendar-year filers need.

Late S Corp Election: Missing the Form 2553 Deadline

If you missed the Form 2553 deadline, you may still qualify for late election relief under Revenue Procedure 2013-30. To qualify, your business must meet S corp eligibility rules and show reasonable cause. You must also file within 3 years and 75 days of the intended effective date. The IRS sends Notice CP261 if approved, or CP264 if denied.

Accepted reasons include:

• Your tax advisor failed to file.
• You did not know how to file Form 2553 as a separate step.

Write the reason on Line I and note "FILED PURSUANT TO REV. PROC. 2013-30" at the top. For full IRS 2553 instructions on late relief, see the IRS page for Rev. Proc. 2013-30.
