IRS Form 2553: How to Elect S-Corp Status for Your LLC (2026)
IRS Form 2553 is the election that tells the IRS you want your LLC taxed as an S-corporation — giving you the salary-plus-distribution split that can save thousands in self-employment tax every year. But the deadline is strict (2 months and 15 days from your tax year start), missing it costs you an entire year, and one missing shareholder signature voids the whole election. This guide walks every line of the form and shows you the exact deadline for your situation.

What Is IRS Form 2553?
IRS Form 2553, "Election by a Small Business Corporation," is the form you file to tell the IRS you want your LLC or corporation taxed as an S-corporation. Without this election, your LLC is taxed by default as a disregarded entity (single-member) or a partnership (multi-member) — and every dollar of profit is hit with 15.3% self-employment tax.
Filing IRS Form 2553 flips that. Once approved, you split your income into a reasonable W-2 salary (subject to payroll tax) and distributions (not subject to self-employment tax). On $120,000 of profit, that split can save $8,000–$12,000 in payroll taxes per year — which is exactly why Form 2553 is one of the most powerful tax moves available to LLC owners.
Like Form 8832, Form 2553 only changes your tax classification. Your LLC stays an LLC under state law.
Form 2553 handles the entity classification automatically.If your LLC is currently a disregarded entity or partnership, you do not need to separately file Form 8832 to reclassify it as a corporation first. Form 2553's Part IV handles that in a single filing — one form only.
Who Can File IRS Form 2553 — S-Corp Eligibility
The IRS has strict eligibility rules for S-corporation status. All of these must be true on the election's effective date. One violation and the election is invalid — or causes automatic termination later.
- 100 or fewer shareholders
- Only US citizens or permanent residents as shareholders
- Only one class of stock (no preferred)
- A domestic LLC or corporation
- Eligible shareholder types (individuals, certain trusts, estates)
- A valid EIN already issued
- More than 100 shareholders
- Any non-resident alien shareholder
- A partnership or corporation as a shareholder
- More than one class of stock
- An ineligible corporation (insurance, DISC, certain banks)
- A foreign-formed entity
Adding an ineligible shareholder terminates S-Corp status.If after your election you admit a non-resident alien, a partnership, or a corporation as a shareholder, your S-Corp status is automatically terminated on that date. This is a common trap for LLCs that later bring in foreign investors. See our LLC for non-US residents guide for the alternative structure in those situations.
S-Corp Election Deadline Calculator
The IRS deadline for IRS Form 2553 is exactly 2 months and 15 days from the first day of the tax year the election is to take effect. Enter your details below for your exact deadline — and to see whether late-election relief is still available if you've already missed it.
New entity vs existing business.For a new LLC whose first tax year starts on a date other than January 1, the deadline is 2 months + 15 days from that start date — not March 15. A business that opens January 7 has until March 21, not March 15. Always use the calculator above with your actual start date.
IRS Form 2553 Instructions — Line by Line
Form 2553 is two pages with four parts. Most LLCs only complete Part I and Part IV. Here's every field explained:
Part I — Election Information
Business Name, EIN & Address
RequiredEnter your LLC's exact legal name as it appears on your formation documents, your EIN (get it free at IRS.gov first if you haven't yet), and the current mailing address. The name must match IRS records exactly.
Employer Identification Number
RequiredYour 9-digit EIN, formatted XX-XXXXXXX. You cannot file Form 2553 without one. If your EIN was just issued, wait a few days before filing so the IRS systems sync.
Date Incorporated / Organized
RequiredFor an LLC, this is the effective date of your Articles of Organization (the date your state approved your LLC formation). Check your state's approval email or Sunbiz record to get this exact date.
State of Incorporation
RequiredThe state where you formed your LLC — the state you filed your Articles of Organization with, not necessarily where you do business.
Effective Date of Election
Required — CriticalThe date you want S-Corp status to begin. For a calendar-year LLC wanting S-Corp status for all of 2026, enter 01/01/2026. This date must be within the 2-month-plus-15-day window relative to your filing date (use the calculator above to verify).
Selected Tax Year
RequiredMost LLCs use a calendar tax year (January 1 – December 31) — check the first option. A fiscal year requires additional justification (Box H) and IRS approval under Section 444 or other rules. Stick with calendar year unless your CPA has a specific reason otherwise.
Name and Title of Officer
RequiredThe name and title of the person signing the form — for most single-owner LLCs, this is the owner/president/managing member. This person certifies under penalties of perjury that all information is accurate.
Fiscal Year Business Purpose
Fiscal year onlyOnly complete if you're electing a fiscal tax year other than calendar year. Leave blank if using a January 1 – December 31 calendar year.
Late Election Reasonable Cause
Late elections onlyIf you're filing a late Form 2553 under Rev. Proc. 2013-30, write "FILED PURSUANT TO REV. PROC. 2013-30" at the top of the form and explain your reasonable cause here. Be specific: "I was not aware of the filing deadline" is acceptable. The IRS approves most timely-filed late-election requests automatically.
Shareholder Information & Consent
Required — Every ShareholderEvery shareholder (member for an LLC) must sign, print their name, enter their SSN/ITIN/EIN, state their ownership percentage, and enter the date they acquired their shares. Every single shareholder must sign. One missing signature voids the entire election. If a shareholder refuses, the election cannot proceed.
Part II — Late Election Relief (Rev. Proc. 2013-30)
Complete Part II only if you missed the deadline but are seeking relief. The requirements: the failure to file on time was due to reasonable cause; all shareholders reported income consistent with S-Corp status; you file within 3 years and 75 days of the intended effective date; and no shareholders are ineligible. Write "FILED PURSUANT TO REV. PROC. 2013-30" at the very top of the form in large text.
Part III — QSST Election
Qualified Subchapter S Trust elections only — completed by the trust beneficiary, not the business. Most LLC owners never touch Part III.
Part IV — Late Corporate Classification + S-Corp Election (LLCs)
This is the LLC-specific section. If your LLC has never filed as a corporation, Part IV tells the IRS to simultaneously treat it as a corporation AND elect S-Corp status. Most LLC owners will complete Part IV. Check the appropriate box confirming you want to be classified as a corporation effective the same date as the S-Corp election.
No photocopies — original only.The IRS requires the original signed Form 2553. Mailing a photocopy may result in rejection. Use the actual printed and hand-signed form, sent to the correct IRS service center for your state.
Form 2553 Deadline — The 2+15 Rule Explained
The statutory deadline for IRS Form 2553 is 2 calendar months and 15 days after the first day of the tax year the election is to take effect. Here's how the math works in practice:
| Scenario | Tax Year Start | 2553 Deadline | Notes |
|---|---|---|---|
| Calendar-year 2026 (existing business) | Jan 1, 2026 | March 16, 2026 | March 15 fell on Sunday; next business day |
| Calendar-year 2027 (existing business) | Jan 1, 2027 | March 15, 2027 | Standard 2+15 from Jan 1 |
| New LLC formed Jan 7, 2026 | Jan 7, 2026 | March 21, 2026 | 2+15 from Jan 7, not Jan 1 |
| New LLC formed August 1, 2025 | Aug 1, 2025 | October 15, 2025 | 2+15 from Aug 1; election covers all of 2025 |
| Prior-year election (any existing) | Any date | Anytime during prior year | File in 2025 for 2026 S-Corp status |
Reasonable Salary — The S-Corp Requirement You Can't Ignore
Once Form 2553 is approved, you must pay yourself a W-2 salary for the work you perform for the S-Corp. This is not optional — it is a legal requirement, and the IRS has won every significant court case when owner-employees took $0 or unreasonably low salaries.
Setting the salary too low triggers reclassification of distributions as wages, back payroll taxes, interest, and penalties. The IRS looks at these factors when auditing reasonable compensation:
- Comparable salaries — what would you pay a non-owner employee to do the same job? Check Bureau of Labor Statistics, Glassdoor, Payscale.
- Time and duties — are you full-time, part-time? What exactly do you do for the business?
- Business revenue — a $30K salary on $500K of profit looks more suspicious than the same salary on $80K of profit.
- $0 salary — always wrong if you perform services. Watson v. Commissioner and Radtke v. United States — the IRS won both.
A common starting-point rule of thumb many CPAs use: set salary at approximately 40–60% of net profit and document the comparable-salary research that supports it. See our how to pay yourself from an LLC guide for the full owner's draw vs S-Corp salary breakdown.
After You File — What Happens Next
- Expect the CP261 notice in ~60 days. This is your official IRS acceptance letter. Keep it permanently with your business records — banks, lenders, and state agencies will ask for it.
- No response after 60 days? Call the IRS Business & Specialty Tax Line at 800-829-4933 with your EIN and filing date ready.
- Set up payroll immediately. From the effective date forward, you must run payroll, withhold taxes, and file quarterly payroll returns (Form 941). Services like Gusto or QuickBooks Payroll typically cost $40–$150/month.
- File Form 1120-S annually. S-Corps file their own tax return (1120-S) by March 15 each year and issue Schedule K-1s to each shareholder. This is more complex than a Schedule C or Form 1065 — budget for a CPA.
- Check your state. Some states (including New York) require a separate state-level S-Corp election in addition to the federal Form 2553. Confirm your state's requirements with your accountant.
Ahmad Adil's Take:IRS Form 2553 is one of the best tax moves available — but only once your profit is consistently above roughly $60K–$80K. Below that, the cost of payroll software ($500–$1,800/yr) plus a CPA for the Form 1120-S ($500–$2,000/yr) typically eats all the savings. Above $80K of net profit, the math almost always works in your favor. On $120K of profit with a $50K salary, you're looking at roughly $9,000 in payroll-tax savings after costs. The key is doing the math before you file — use the calculator on our how to pay yourself page, then have a CPA document your reasonable salary before your first payroll. Don't set the salary without research — that's the one thing that triggers audits.
