Form 2553: How to Elect S Corporation Status
Form 2553 is the IRS election that lets an eligible corporation or LLC be taxed as an S corporation under IRC Section 1362(a). File it no later than 2 months and 15 days after the start of the tax year the election should take effect, or any time in the preceding tax year. The form cannot be e-filed: you mail or fax it to the Kansas City or Ogden service center, and the IRS responds within about 60 days.
The main draw is pass-through taxation combined with a payroll structure that can lower self-employment tax. Business income flows to shareholders and skips the 21% corporate-level tax, while a shareholder-employee splits pay between wages (subject to the 15.3% FICA rate) and distributions (not subject to it). That split only holds if the wage is defensible, which is where reasonable compensation comes in.
Who is eligible to file Form 2553
To elect S corporation status, the entity must be a domestic corporation (or a domestic LLC electing corporate treatment) that meets four shareholder and stock tests: no more than 100 shareholders, only eligible shareholder types, one class of stock, and no disqualified status. Failing any single test blocks the election or terminates it later.
The IRS eligibility rules under IRC Section 1361 are specific:
| Requirement | Rule | Notes |
|---|---|---|
| Entity type | Domestic corporation, or domestic entity eligible to elect corporate classification | An LLC files Form 8832 concepts implicitly; Form 2553 can serve as the corporate election too |
| Shareholder count | 100 or fewer | A family (per IRC Section 1361(c)(1)) counts as one shareholder; a married couple and their estates count as one |
| Eligible shareholders | Individuals, certain estates, and certain trusts | Section 401(a) and 501(c)(3) organizations may qualify |
| Nonresident aliens | Not permitted | A single nonresident alien shareholder can disqualify the election |
| Stock classes | One class of stock only | Differences in voting rights are allowed; differences in distribution or liquidation rights are not |
LLCs can elect S status. An LLC that has not already elected to be taxed as a corporation may file Form 2553 by itself, and the IRS treats the timely S election as also electing corporate classification, so a separate Form 8832 is often unnecessary. For the mechanics of that classification choice, see the Form 8832 entity classification election guide.
The 2-months-and-15-days deadline
Form 2553 must be filed no more than 2 months and 15 days after the beginning of the tax year the election is to take effect, or at any time during the tax year that precedes it. For a calendar-year business starting January 1, that puts the deadline at March 15. Miss it, and the election generally applies to the following tax year unless late relief applies.
The IRS calculates the 2-month window precisely. The period begins on the day of the month the tax year starts and ends with the close of the day before the numerically corresponding day of the second calendar month that follows. If there is no corresponding day, use the last day of that month.
| Tax year begins | 2-month point | Add 15 days: deadline |
|---|---|---|
| January 1 | March 1 | March 15 |
| April 1 | June 1 | June 15 |
| A new corporation’s first day (say, June 5) | August 5 | August 20 |
A new corporation’s tax year starts on the earliest date it has shareholders, acquires assets, or begins doing business, whichever comes first, not the incorporation date on the certificate. Getting that trigger date wrong is a common reason an election lands outside the window.
How to file Form 2553: numbered steps
Filing is a paper process. There is no e-file option, so plan for mail or fax and a wait of up to 60 days for the IRS acceptance letter (CP261). Faxing typically clears two to four weeks faster than mail and gives you an instant transmission record.
- Confirm eligibility. Verify the 100-shareholder cap, one-class-of-stock rule, and eligible shareholder types before you start. One nonresident alien or a second stock class defeats the election.
- Set the effective date. Enter the date the election should begin in Part I. For a new entity this is usually the tax-year start date; for an existing C corporation it is the first day of the target tax year.
- Choose the tax year. Most S corporations use a calendar year. If you want a fiscal year, complete Part II and establish a business purpose or a Section 444 election, which adds steps and often a required payment.
- Collect shareholder consents. Every shareholder as of the effective date (and any who held stock earlier in the year for a late election) must sign the consent in Part I, column K, or on an attached statement. Missing a signature invalidates the filing.
- Complete officer information and sign. An authorized officer signs and dates the form. Enter the corporation’s legal name, EIN, and formation date exactly as they appear on IRS records.
- Send to the correct service center. Mail or fax to Kansas City, MO or Ogden, UT depending on the state of your principal business, per the current Form 2553 instructions. Keep the fax confirmation or certified-mail receipt.
- Wait for the CP261 acceptance letter. The IRS responds within roughly 60 days. If you have not heard back, call the IRS Business and Specialty line rather than refiling.
Late election relief under Rev. Proc. 2013-30
If you miss the deadline, Revenue Procedure 2013-30 provides a streamlined path to relief without a private letter ruling. You must file the late Form 2553 within 3 years and 75 days of the intended effective date, write “FILED PURSUANT TO REV. PROC. 2013-30” across the top, and attach a reasonable-cause statement signed under penalty of perjury.
Four conditions must all be met, per Rev. Proc. 2013-30 and the IRS late election relief guidance:
- The entity intended to be an S corporation as of the effective date.
- It failed to qualify solely because the election was not timely filed.
- There is reasonable cause for the failure, and the entity acted diligently to fix it once discovered.
- The corporation and all shareholders reported income consistently with S corporation status for every affected year (for example, filing Form 1120-S and matching K-1s).
Common reasonable-cause facts include a return preparer or advisor who failed to file, or an owner who believed the election was handled at formation. The consistency requirement can be the hard part: if shareholders filed as a C corporation or as a disregarded LLC in the interim, streamlined relief may not fit and a private letter ruling could be required.
Reasonable compensation for shareholder-employees
Once the S election is in place, any shareholder who performs substantial services must be paid reasonable compensation as W-2 wages before taking distributions. The IRS defines reasonable compensation as what a like enterprise would pay for similar services under similar circumstances. Wages carry the 15.3% combined Social Security and Medicare tax; distributions do not.
This is where the S corporation tax benefit is won or lost. Paying too little salary to shift income into tax-free distributions invites the IRS to reclassify distributions as wages, with back payroll taxes plus penalties that can reach 20% and interest. Courts have repeatedly upheld that reclassification authority.
There is no fixed formula, and the old “60/40” split is not an IRS rule. A defensible figure usually starts from market data: what comparable businesses pay for the same role, the owner’s time and skill, and the share of profit attributable to labor versus capital. Reasonable compensation interacts with basis and loss limits, covered in the Form 7203 S corporation shareholder basis guide, and with the 20% qualified business income deduction, detailed in the Section 199A QBI deduction analysis.
Should you elect S corporation status
An S election can lower total tax when profit comfortably exceeds a reasonable salary, because the excess flows out as distributions free of the 15.3% payroll tax. It adds costs too: payroll administration, a separate Form 1120-S, and state-level treatment that varies. For a side-by-side of the alternatives, see the business entity comparison and the S Corporation Report 2026 for population-level data on returns and net income.
The rough breakeven is where payroll-tax savings on distributions outweigh the added compliance cost. Many advisors flag net profit in the range of roughly $40,000 to $80,000 and up as the zone where the election starts to pay, though the right threshold depends on the owner’s reasonable salary, state taxes, and benefits. Run the numbers for your situation before electing.
Frequently asked questions
What is the deadline to file Form 2553?
File Form 2553 no more than 2 months and 15 days after the start of the tax year the election should take effect, or any time during the preceding tax year. For a calendar-year business, that means March 15. A new corporation counts from the first day it has shareholders, acquires assets, or begins business, not the incorporation date.
Can I file Form 2553 late?
Yes, in many cases. Revenue Procedure 2013-30 allows late relief if you file within 3 years and 75 days of the intended effective date, show reasonable cause, confirm all shareholders reported consistently with S status, and write “FILED PURSUANT TO REV. PROC. 2013-30” on the form. If those conditions are not met, a private letter ruling may be needed instead.
Can an LLC file Form 2553?
Yes. A domestic LLC eligible for corporate classification can elect S corporation status by filing Form 2553. If the LLC has not previously elected corporate treatment, a timely Form 2553 is generally treated as also making the corporate classification election, so a separate Form 8832 is often not required. The LLC must still meet all S corporation eligibility tests.
How long does the IRS take to approve Form 2553?
The IRS generally issues an acceptance or denial letter (CP261 for acceptance) within about 60 days of filing. Faxing the form usually processes two to four weeks faster than mailing. If 60 days pass with no response, contact the IRS Business and Specialty Tax line rather than filing a duplicate, which can cause processing errors.
Do I have to pay myself a salary in an S corporation?
If you are a shareholder who performs substantial services, yes. The IRS requires reasonable compensation paid as W-2 wages before distributions. Wages are subject to the 15.3% FICA tax; distributions are not. Paying an unreasonably low salary risks reclassification of distributions as wages, plus back taxes, penalties up to 20%, and interest.
Can I e-file Form 2553?
No. Form 2553 cannot be e-filed. You must mail or fax the completed form, signed by an authorized officer and all consenting shareholders, to the IRS service center in Kansas City, MO or Ogden, UT based on your principal business location. Faxing gives an immediate transmission record and typically clears faster than mail.
