TL;DR
IRS Form 2553, titled “Election by a Small Business Corporation,” is the form you file to elect S-Corp tax status for your business. It must be submitted by mail or fax within two months and 15 days of the start of the tax year (March 16, 2026, for calendar-year businesses). Filing it doesn’t change your legal structure. It only changes how the IRS taxes you. If you missed the deadline, late election relief is available under Revenue Procedure 2013-30.
What Is IRS Form 2553?
IRS Form 2553, officially titled “Election by a Small Business Corporation,” is the form that eligible domestic corporations and LLCs use to elect S-Corporation tax status under Internal Revenue Code §1362(a). Think of it as a request to the IRS: “Tax this business as an S-Corp going forward.”
Filing Form 2553 does not change your legal structure. Your LLC remains an LLC. Your corporation remains a corporation. The form only changes the tax classification, telling the IRS to apply pass-through taxation instead of the default C-Corp rules.
The form was last revised in December 2017, with instructions updated in December 2020. Despite those dates, it remains the current version the IRS accepts.

Who Files Form 2553?
Two types of businesses file this form: domestic corporations and LLCs that want S-Corp taxation.
To qualify, your business must pass all five eligibility tests under IRC §1361(b) simultaneously and continue meeting them every day after the election:
Domestic corporation. The business must be organized in the United States.
100 shareholders or fewer. Family members (as defined under §1361©(1)(B)) and their estates can be treated as a single shareholder. A married couple also counts as one.
Only eligible shareholders. Shareholders must be U.S. individuals, estates, or certain qualifying trusts. Partnerships, corporations, and nonresident aliens cannot hold S-Corp stock.
One class of stock. You can have voting and non-voting shares, but all shares must carry identical distribution and liquidation rights.
Not an ineligible corporation type. Banks using the reserve method for bad debts and certain insurance companies are disqualified.
Fail any one of these tests and your S-Corp election terminates.
One important note: LLCs do not need to file Form 8832 before filing Form 2553. Part IV of Form 2553 handles the entity reclassification automatically. You’ll need an EIN first, though. If you haven’t obtained one yet, you can apply using Form SS-4.
Why Businesses File It
The primary motivation is tax savings. An S-Corp is a pass-through entity, meaning the business itself pays no federal income tax. Instead, profits and losses flow through to the owners’ personal tax returns.
The bigger benefit for most small business owners is the reduction in self-employment tax. As a sole proprietor or single-member LLC, you pay 15.3% self-employment tax on net earnings up to the 2026 wage base of $184,500, then 2.9% on everything above that. With S-Corp status, you split your income between a reasonable salary (subject to payroll tax) and distributions (not subject to self-employment tax).
That split can save between $5,000 and $20,000 or more annually, depending on your income.
When Does the Math Make Sense?
S-Corp status adds compliance costs: payroll processing, Form 1120-S filing, and often higher accounting fees. For most business owners, the tax savings outweigh these costs when net income exceeds roughly $50,000 to $60,000 per year. Below that threshold, the added complexity usually isn’t worth it.
Filing Deadline for Form 2553
The general rule: file within two months and 15 days of the beginning of the tax year you want the S-Corp election to take effect.
For a calendar-year business wanting S-Corp status for 2026, that means filing by March 16, 2026 (since March 15 falls on a Sunday). For a new business that starts on January 7, the two-month period ends March 6, and 15 days later gives you until March 21.
You can also file Form 2553 during the tax year preceding the one you want the election to begin. So filing in December 2025 for a January 1, 2026 effective date works perfectly.
The deadline is strict. Miss it by even a day, and you’ll need to go through the late election relief process, which adds complexity and stress.
How to Submit Form 2553
Here’s something that surprises many people: the IRS does not accept electronically filed Form 2553. You must submit it by mail or fax. That’s it.
Mailing Addresses
The IRS splits filings between two processing centers based on your state of principal business:
Your Business Location | Mail To | Fax To |
|---|---|---|
25 eastern and midwestern states | Department of the Treasury, IRS, Kansas City, MO 64999 | 855-887-7734 |
25 western and southern states | Department of the Treasury, IRS, Ogden, UT 84201 | 855-214-7520 |
Check the IRS instructions for the exact state-by-state breakdown.
Practical Tips
Most CPAs fax the form because it’s faster and creates a transmission confirmation as proof of filing. If you mail it, use certified mail with a return receipt. Practitioners on Reddit and tax forums consistently warn that sending Form 2553 to the wrong processing center can delay your election by weeks.
When a tax professional files on your behalf, they may also need to submit Form 2848 (Power of Attorney) to act as your authorized representative with the IRS.
Parts of the Form: Quick Overview
IRS Form 2553 has four parts. Not every filer needs all of them.
Part | Purpose | Who Needs It |
|---|---|---|
Part I | Core election info: entity name, EIN, date of incorporation, state, effective date, tax year, and shareholder consent signatures | Everyone |
Part II | Fiscal year selection | Only if requesting a tax year other than the calendar year |
Part III | Qualified Subchapter S Trust (QSST) elections | Only if a trust is a shareholder |
Part IV | Late corporate classification election | LLCs electing S-Corp status (handles the entity reclassification so you skip Form 8832) |
Part I is where most of the action happens. Every shareholder must sign the consent section (Columns J through N). Unanimous shareholder consent is required, and missing even one signature is grounds for rejection.
Accountants and attorneys handling S-Corp elections for multiple clients can speed up this process considerably. Auto-fill IRS forms from saved client profiles instead of retyping the same data across dozens of filings.
Common Mistakes to Avoid
Practitioner forums are full of cautionary tales about Form 2553 errors. Here are the ones that come up most frequently:
Missing shareholder signatures. Form 2553 requires every shareholder to sign, including spouses if they jointly own LLC interests. A husband-and-wife LLC where only one spouse signs is a classic rejection trigger.
Community property state trap. If any shareholder lives in a community property state (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin), their spouse may need to sign the consent section even if the spouse is not listed as a shareholder. Practitioners on tax forums report that this catches even experienced CPAs off guard.
Wrong mailing address. Sending Form 2553 to the wrong IRS processing center doesn’t kill the election, but it can delay processing significantly. Double-check your state’s assigned center.
Incorrect effective date on late filings. The intended effective date must match when the entity actually started operating as an S-Corp. If the business opened a bank account in March and started payroll in April but tries to claim a January 1 effective date, the IRS may question it.
Forgetting the state-level S-Corp election. Federal and state elections are separate. One practitioner at a tax advisory firm notes that it’s common to fix the federal election and forget the state. Two years later, the state issues a notice questioning the S-Corp filings.
CPA errors and E&O insurance. Here’s something rarely discussed: if a CPA or tax preparer made the original Form 2553 error (missed the deadline, wrong address, missing signatures), their errors-and-omissions insurance may cover the cost of filing the late election, preparing a private letter ruling, and even the back-year tax cost if relief is denied. Ask your preparer about this if their mistake caused the problem.
Late Election Relief
Missing the filing deadline for Form 2553 is one of the most common tax mistakes among LLC owners. The good news: the IRS provides a clear path to fix it.
Revenue Procedure 2013-30
If fewer than three years and 75 days have passed since your intended effective date, you can file Form 2553 late under Rev. Proc. 2013-30. Three conditions must be met:
The entity failed to qualify as an S-Corp solely because the election wasn’t filed on time.
Every shareholder reported income on their personal returns as if the S-Corp election was already in effect (Schedule E from K-1s, not Schedule C).
You include a reasonable cause statement explaining why the election was late.
When filing the late election, write “FILED PURSUANT TO REV. PROC. 2013-30” in the top margin of the first page of Form 2553.
The Reasonable Cause Statement
The IRS isn’t looking for a legal brief. A short paragraph of three to five sentences explaining what happened works best. Practitioners report that a one-sentence “we forgot” sometimes gets flagged for follow-up, while a novel-length explanation is overkill. Describe the circumstances honestly and briefly.
Outside the Relief Window?
If more than three years and 75 days have passed, a private letter ruling (PLR) is the only remaining option. PLR user fees start at $3,500 and can exceed $28,000 depending on your gross income, with no guarantee the IRS will approve your request. This is a last resort.
Form 2553 vs. Form 8832
This is one of the most confused areas in small business tax, and getting it wrong creates real problems.
Form 2553 | Form 8832 | |
|---|---|---|
Purpose | Elects S-Corp tax status | Changes entity classification (e.g., LLC to corporation) |
Result | S-Corp taxation (pass-through) | C-Corp taxation (double taxation) unless Form 2553 is also filed |
Does an LLC need it for S-Corp? | Yes, this is the only form needed | No, not required. Part IV of Form 2553 covers it |
Common mistake | None specific | Filing Form 8832 thinking it creates S-Corp status. It doesn’t. It creates C-Corp treatment. |
The bottom line: if your LLC wants S-Corp taxation, file Form 2553 only. Do not file Form 8832. An LLC owner who files Form 8832 thinking they’re electing S-Corp status ends up with C-Corp double taxation instead.
After the IRS Approves Your Election
Confirmation Timeline
The IRS typically processes Form 2553 within 60 days. You should receive a CP-261 confirmation letter accepting your election. If the election is denied, you’ll receive a notice explaining why.
If nothing arrives after 60 days, call the IRS Business & Specialty Tax Line at 800-829-4933 to verify receipt and processing status. You can also request Form 4506-T transcripts to confirm your S-Corp status is on file.
Ongoing Obligations
The election stays in effect until you revoke it or the company stops meeting the eligibility requirements. But S-Corp status comes with year-round responsibilities:
File Form 1120-S annually. This is the S-Corp’s information return.
Issue Schedule K-1s to shareholders. Each shareholder gets a K-1 showing their share of income, deductions, and credits.
Pay yourself a reasonable salary. The IRS scrutinizes S-Corp owners who take all income as distributions and zero salary. That’s a red flag.
Run payroll and file payroll tax returns. Quarterly Form 941 filings, annual Form 940, W-2s for shareholder-employees.
Track shareholder basis. This determines the tax treatment of distributions and the deductibility of losses.
Ignoring these obligations can lead to penalties, back taxes, or involuntary termination of your S-Corp election.
Frequently Asked Questions
Can I file Form 2553 online?
No. The IRS does not accept electronically filed Form 2553. You must submit it by mail or fax. Most practitioners prefer fax because it provides immediate transmission confirmation.
Does an LLC need to file Form 8832 before Form 2553?
No. Part IV of Form 2553 handles the entity reclassification for LLCs. Filing Form 8832 separately is unnecessary and can actually cause problems if done incorrectly.
How long does IRS processing take?
About 60 days. You’ll receive a CP-261 confirmation letter if approved. If you hear nothing after 60 days, call 800-829-4933.
Can a single-member LLC file Form 2553?
Yes. A single-member LLC can elect S-Corp status by filing Form 2553. The LLC must also meet all five eligibility requirements (domestic entity, eligible shareholders, one class of stock, etc.).
What if the IRS rejects my Form 2553?
The IRS will send a notice explaining the rejection reason. Common causes include missing shareholder signatures, ineligible shareholders, or filing past the deadline without a late election statement. You can correct the issue and refile.
Is there a fee to file Form 2553?
No. There is no filing fee for Form 2553 itself. However, if you need a private letter ruling for a late election outside the Rev. Proc. 2013-30 window, PLR fees start at $3,500.
Do I need to file Form 2553 every year?
No. The S-Corp election is a one-time filing. Once approved, it remains in effect until you voluntarily revoke it or your business fails to meet the eligibility requirements.
What is the deadline for the 2026 tax year?
For calendar-year businesses, the deadline to file IRS Form 2553 for 2026 S-Corp status is March 16, 2026.
