Form 2553 Explained — How to File the S-Corp Election (2026 Guide)

Form 2553 is the IRS document you file to elect S-Corporation tax treatment for an eligible LLC or corporation, and it is due no later than 2 months and 15 days after the beginning of the tax year you want the election to take effect. Miss that window and you can still qualify for late-election relief under Rev. Proc. 2013-30 for up to 3 years and 75 days — but only if you meet the reasonable-cause standard and have consistently treated the entity as an S-Corp on your books.

Updated September 2026

What Form 2553 does

Form 2553 ("Election by a Small Business Corporation") tells the IRS to tax your eligible entity under Subchapter S of the Internal Revenue Code. That means profits and losses pass through to shareholders, the entity itself pays no federal income tax, and the owner-operator splits compensation between a W-2 salary (subject to payroll tax) and distributions (not subject to self-employment tax).

Filing 2553 does not change your legal structure. If you had an LLC before you filed, you have an LLC after. Only the tax classification changes. If you want the full economic case for whether to file this form at all, see our LLC vs S-Corp break-even analysis.

Who can file Form 2553

The eligibility rules are strict. Your entity must meet all of the following:

• Domestic entity. Formed under US federal or state law. Foreign entities cannot elect S-Corp status.
• 100 shareholders or fewer. Family members can be counted as a single shareholder under specific rules.
• One class of stock. Voting differences are allowed; economic-rights differences are not.
• Allowable shareholders only. US individuals, certain trusts (grantor, QSST, ESBT, testamentary), and estates. No partnerships, no C-corporations, and no non-resident aliens.
• Eligible tax year. A calendar year or a permitted fiscal year with a business purpose (rarely approved).
• Not an ineligible corporation. Certain financial institutions, insurance companies, and international sales corporations are excluded.

For LLCs specifically: your LLC must have a valid EIN before you file 2553. If you have not yet gotten your EIN, follow the walkthrough in our EIN guide or the IRS SS-4 process first.

Line-by-line walkthrough of Form 2553

Form 2553 is four parts. Most single-owner LLCs only complete Parts I and II. Parts III and IV apply in narrow situations.

Part I — Election Information

Name, address, EIN. The exact legal name of the entity as filed with the state. If your LLC is registered as "Acme Widgets LLC," write it exactly that way. The EIN must match the one on your IRS records. A mismatch is the second most common rejection reason.

Item A — Employer Identification Number. The nine-digit EIN issued on your CP 575 letter.

Item B — Date incorporated. For an LLC, this is the date the state approved your Articles of Organization — not the date you signed them, not the date you filed them, but the date the state stamped them approved. Get this from your state filing receipt.

Item C — State of incorporation. The state where you filed.

Item D — Name change checkbox. Only check this if you have changed your entity name since applying for the EIN and you have not notified the IRS.

Item E — Effective date of election. The single most important line on the form. Enter the first day of the tax year you want S-Corp treatment to begin. For a new LLC, this is usually the formation date. For an existing LLC electing mid-year, enter January 1 of the current year (if you are within the 2-month-15-day window) or January 1 of the next year (if you are not).

Item F — Tax year. Check the box for calendar year unless you have a fiscal-year business purpose approved.

Item G — More than 100 shareholders. Rarely applies. Uses family aggregation rules.

Item H — Name and phone of contact. The person the IRS should call with questions.

Item I — Late-election explanation. Only complete if filing late under Rev. Proc. 2013-30. See below.

Signature block. An officer or authorized member/manager signs.

Part I continued — Shareholder Consent

Every shareholder as of the effective date must sign the consent block. Column J is the shareholder’s name and address; column K is the number of shares and date acquired; column L is the shareholder’s SSN or EIN; column M is the shareholder’s tax year end. Column N is the signature.

For a single-member LLC, this is one row. For a multi-member LLC or corporation, every shareholder signs. If a shareholder is a trust, the trustee signs. If a shareholder is an estate, the executor signs. Community property states: both spouses must consent even if only one is a legal owner.

Part II — Fiscal Year Election

Only complete if you are requesting a fiscal year other than a calendar year. Ninety-plus percent of small businesses file calendar-year and skip Part II entirely.

Part III — QSST Election

Only complete if a Qualified Subchapter S Trust is a shareholder. Rare for single-owner and small partnership situations.

Part IV — Late Election Relief for Corporations

Only complete if you are filing late and the entity is a corporation (not an LLC). LLCs use a slightly different mechanism — see the late-election section below.

The 75-day deadline with a real calendar

The rule: Form 2553 must be filed no later than 2 months and 15 days after the beginning of the tax year the election is to take effect.

Calendar-year filers

If your tax year starts January 1, your deadline is March 15. That is 2 months (through February) + 15 days into March. It is the same as the S-Corp tax return deadline, which is not a coincidence.

Mid-year formation

If you formed your LLC on, say, May 1, 2026, and want S-Corp treatment from day one, the deadline is 2 months + 15 days from May 1, which is July 15, 2026. Miss that and you fall back to late-election relief or wait until January 1, 2027.

Common deadline scenarios

Worked example. You formed "Cedar Ridge Consulting LLC" in Texas on June 20, 2026. You want S-Corp taxation from formation. Deadline = June 20 + 2 months + 15 days = September 4, 2026. File Form 2553 on or before September 4, 2026 — postmarked in time counts. If you miss it, you can still elect for 2027 by filing by March 15, 2027, or you can file late under Rev. Proc. 2013-30 to preserve the June 20, 2026 effective date.

Late election relief (Rev. Proc. 2013-30)

The IRS anticipated that people would miss the 2-month-15-day deadline and built a formal relief procedure. Rev. Proc. 2013-30 — issued in June 2013 and still current in 2026 — lets you file a late Form 2553 up to 3 years and 75 days after the intended effective date, with a simple attached statement, as long as you meet the eligibility conditions.

Eligibility for Rev. Proc. 2013-30 relief

• The entity intended to be an S-Corp as of the intended effective date.
• The entity failed to be an S-Corp solely because Form 2553 was not filed on time.
• The entity has reasonable cause for the late filing.
• The entity and all shareholders have consistently treated the entity as an S-Corp on their tax returns since the intended effective date (or have not yet filed for that year).
• The request is filed within 3 years and 75 days of the intended effective date.

How to file the late election

Complete Form 2553 normally, filling in the effective date you originally wanted. Write across the top of the form (or attach as a cover statement) the exact wording:

FILED PURSUANT TO REV. PROC. 2013-30

Then attach a reasonable-cause statement. It should explain, briefly and honestly, why the filing was late. Common accepted reasons include: reliance on a tax professional who failed to file, entity formation confusion, illness, natural disaster, or simple oversight. All shareholders sign a statement declaring they have reported income consistent with S-Corp treatment since the intended effective date.

When the IRS accepts vs rejects

The IRS accepts the vast majority of well-formed Rev. Proc. 2013-30 requests. Rejections typically happen when: the 3-year-75-day window has passed, the entity actually filed a Form 1065 (partnership) or Schedule C (sole prop) for a year covered by the requested election (which contradicts the "consistently treated as S-Corp" requirement), or a shareholder is ineligible (non-resident alien, partnership, C-corp).

What happens after you file

The CP 261 acceptance letter

The IRS mails a CP 261 notice when they approve the election. Timeline: typically 45–60 days from filing, sometimes as fast as 3 weeks, sometimes as slow as 6 months during peak tax season. Keep this letter forever — you will need it for banking, financing, and any state-level S-Corp registration.

Timeline expectations

File by fax if you can (faster than mail; check the current 2553 instructions for the right fax number by state). If you file by mail, use certified mail with return receipt so you have proof of timely filing. Do not follow up before day 60 — the IRS asks that you wait.

Backup filing tips

File your first S-Corp Form 1120-S even if the CP 261 hasn’t arrived yet, if the S-Corp filing deadline hits first. On the 1120-S, write "S ELECTION FILED [DATE] AWAITING CP 261" across the top. This preserves your timely filing status.

Common rejection reasons

The eight most common reasons the IRS rejects Form 2553:

1. Missing shareholder signatures. Every shareholder as of the effective date must sign. Missing signatures = automatic reject. In community property states, both spouses must sign.
2. Wrong EIN. The EIN on 2553 does not match the EIN the IRS has on file. Double-check against your CP 575 letter.
3. Wrong effective date. Date is before the entity was legally formed, or is set for a year that has already passed without late-relief invocation.
4. Ineligible entity. The filer is a foreign entity, a partnership, or has non-eligible shareholders (partnership, C-corp, non-resident alien).
5. More than one class of stock. The entity has different classes of shares with different economic rights.
6. Missed 75-day deadline without Rev. Proc. 2013-30 statement. Late filed and the "FILED PURSUANT TO REV. PROC. 2013-30" language is missing.
7. Entity name mismatch. The legal entity name on 2553 does not match the state or IRS records exactly. "Acme Consulting" instead of "Acme Consulting LLC" will get bounced.
8. Non-resident alien shareholder. Any shareholder without US residency triggers immediate rejection. This is why foreign-owned LLCs cannot elect S-Corp status.

What if you get a CP 262 rejection notice

CP 262 is the IRS notice that says your S election was denied. Do not panic. The letter states the reason for rejection. In most cases the fix is straightforward: re-file 2553 with the correction (missing signature, corrected EIN, added Rev. Proc. 2013-30 statement) and re-submit.

If the rejection is because of a missed deadline, your options are: (a) re-file under Rev. Proc. 2013-30 if you are within 3 years and 75 days, or (b) accept default LLC or C-Corp tax treatment for the year in question and re-elect for the following year.

If the rejection is because of an ineligible shareholder or ineligible entity, the S-Corp path is closed until you remove the ineligibility. This is common for foreign-owned LLCs.

Once your S-Corp election is in place, you will want to build out the rest of the operating stack — payroll, quarterly estimates, and if you are running multiple businesses, an appropriate holding structure.

Frequently Asked Questions

Do I need to file Form 8832 before Form 2553 for an LLC?

No. Rev. Proc. 2013-30 and long-standing IRS practice allow an LLC to elect S-Corp status directly on Form 2553 without first filing Form 8832 to elect corporate treatment. The 2553 filing is treated as a deemed election of corporate status followed by an S election.

Can I file Form 2553 online?

Not directly through IRS.gov as of 2026. You must file by mail or by fax. Fax filing is faster and gives you a transmission confirmation as proof of timely filing.

What is the difference between Form 2553 and Form 8832?

Form 8832 elects an entity classification (partnership, disregarded entity, or corporation). Form 2553 elects S-Corp tax status specifically. LLCs electing S-Corp file only Form 2553; 8832 is not required.

How much does it cost to file Form 2553?

The IRS charges no filing fee for Form 2553. If you hire a CPA or formation service to prepare and file it, expect $150 to $400 for the service.

Can I revoke an S election after filing Form 2553?

Yes, by filing a written revocation statement with the IRS signed by shareholders holding more than 50% of the shares. You generally cannot re-elect S-Corp status for five years after revocation without IRS consent.

What happens if my Form 2553 gets lost in the mail?

If you kept certified mail proof, you can request a duplicate processing based on the postmark. Without proof, you may need to re-file under Rev. Proc. 2013-30 as a late election. Always send by certified mail with return receipt, or fax.

Can a foreign-owned LLC file Form 2553?

No. S-Corp shareholders must be US individuals, certain trusts, or estates. A non-resident alien owner disqualifies the entity from S-Corp treatment. Foreign-owned LLCs typically file as disregarded entities or partnerships, with Form 5472 obligations.
