How to Elect S-Corp Status — IRS Form 2553, Step by Step
Electing S-Corporation status is a one-page IRS form, but the deadlines and signatures trip up most owners. Here's exactly how to do it right.
What Form 2553 actually does
Form 2553 (Election by a Small Business Corporation) tells the IRS that your eligible LLC or corporation wants to be taxed under Subchapter S instead of as a sole proprietorship, partnership, or C-Corp. Your legal entity does not change — only how the IRS taxes its profits.
Eligibility checklist
- Domestic LLC or corporation
- 100 or fewer shareholders
- Only one class of stock
- All shareholders are individuals (or eligible trusts/estates) — no partnerships or corporations
- All shareholders are U.S. citizens or resident aliens
- Calendar tax year (or a valid business-purpose fiscal year)
The deadlines that matter
For a current-year election, Form 2553 is due no later than two months and 15 days after the start of the tax year. For calendar-year filers that is March 15. File any time during the prior tax year for an election effective on January 1.
Miss the deadline? The IRS allows late elections under Rev. Proc. 2013-30 with reasonable cause — see our late S-Corp election guide for the exact relief language to attach.
Step-by-step: filing Form 2553
- Confirm you have an EIN. If your LLC was disregarded previously, you may need to apply for one before filing.
- Pick the effective date. Most owners pick January 1 of the current year. Mid-year elections are allowed but create a short-period return.
- Complete Part I. Entity name, EIN, state of incorporation, effective date, and tax year.
- Have every shareholder sign Part I, column K. In community-property states, the shareholder's spouse must also sign.
- Complete Part II only if you are requesting a non-calendar fiscal year.
- Mail or fax to the IRS service center for your state. The IRS does not accept Form 2553 electronically. Use certified mail or keep the fax confirmation.
- Wait 60 days for CP261 confirmation. If you do not receive it, call the IRS Business & Specialty line to confirm.
What changes the day the election takes effect
- You must run real payroll for any owner-officer who works in the business
- You file Form 1120-S annually instead of reporting on Schedule C or Form 1065
- Each shareholder gets a Schedule K-1 reporting their share of profit/loss
- You need to track shareholder basis to determine the tax treatment of distributions
- Multi-state operations may require additional state-level S-Corp elections — see multi-state payroll

Frequently Asked Questions
What's the deadline to elect S-Corp for this tax year?
Form 2553 is due no more than two months and 15 days after the start of the tax year you want the election to take effect. For calendar-year businesses, that's March 15.
Can I still elect if I missed the deadline?
Yes — Rev. Proc. 2013-30 allows late S-Corp elections up to 3 years and 75 days after the intended effective date if you have a reasonable cause. See our late-election guide at /scorp/late-election.
Do all shareholders have to sign?
Yes. Every shareholder (and their spouse, in community-property states) must sign the consent statement on Form 2553. Missing signatures are the #1 reason elections get rejected.
