Form 2553: How to Make an S Corp Election (2026 Guide)

Quick answer: Form 2553 is the IRS form an eligible corporation or LLC files to be taxed as an S corporation. For the election to apply to a calendar tax year, file it no later than 2 months and 15 days after the year begins (March 15 for most businesses), with every shareholder's signed consent.

The S corp election is one of the most talked-about tax moves for profitable freelancers and small businesses, mainly because it can reduce self-employment tax. It also adds payroll, a separate business return and stricter rules about how you pay yourself. This guide walks through who qualifies, how to fill out Form 2553 line by line, the deadlines for the 2027 tax year, late election relief, and a worked example of the potential savings. It is general information, not tax or legal advice.

What is Form 2553 and what does an S corp election do?

Form 2553, Election by a Small Business Corporation, tells the IRS that your business wants to be taxed under Subchapter S of the Internal Revenue Code. An S corporation is not a separate type of company under state law. It is a tax status that a corporation or an LLC can choose.

Once the election is in place, the business generally pays no federal income tax itself. Profits and losses pass through to the owners on Schedule K-1, and each owner reports them on their personal Form 1040. The difference from a regular sole proprietorship or default LLC is how the owner's pay is treated:

• Salary: owner-employees who work in the business must receive reasonable compensation through payroll, with Social Security and Medicare (FICA) taxes withheld and matched.
• Distributions: remaining profit can be paid out as distributions, which are not subject to FICA or self-employment tax.

That split is where the potential saving comes from. Without the election, a single-member LLC owner pays self-employment tax of 15.3% on nearly all net earnings up to the Social Security wage base. For a side-by-side look at entity choices, see S corp vs LLC and LLC vs corporation.

Who is eligible to file Form 2553?

To elect S corp status, the business must meet all of these tests, as listed in the IRS instructions for Form 2553:

• It is a domestic corporation, or an LLC that is eligible to be treated as a corporation.
• It has no more than 100 shareholders (family members can be counted as one).
• Shareholders are individuals, certain trusts and estates, or certain exempt organizations. Partnerships, corporations and nonresident aliens cannot be shareholders.
• It has only one class of stock (differences in voting rights alone are allowed).
• It is not an ineligible corporation, such as certain banks and insurance companies.
• It uses a permitted tax year, usually the calendar year.

You also need an Employer Identification Number before you file. If you do not have one, our guide on how to get an EIN covers the free online application.

When is the Form 2553 deadline?

The election is due no more than 2 months and 15 days after the beginning of the tax year it should take effect, or at any time during the preceding tax year. For a calendar-year business, that means March 15. If the 15th falls on a weekend or legal holiday, the deadline moves to the next business day.

Situation	When to file Form 2553	Election effective
Existing calendar-year business wants S status for 2027	Any time in 2026, or by March 15, 2027	January 1, 2027
New corporation or LLC formed June 1, 2027	Within 2 months and 15 days of June 1 (by mid-August 2027)	June 1, 2027
Filed after March 15, 2027 with no relief requested	Any time in 2027	January 1, 2028
Missed deadline, qualifies for Rev. Proc. 2013-30	Within 3 years and 75 days of intended date	Intended date, if relief granted

For a newly formed entity, the tax year starts on the earliest of the date it has shareholders, acquires assets or begins doing business. Count your 2 months and 15 days from that date. Keep all the business filing dates in one place with our 2027 business tax deadlines calendar.

How to fill out Form 2553 step by step

1. Part I, name and identity: enter the legal name exactly as on your EIN confirmation letter, the address, the EIN, the date and state of incorporation or formation, and the effective date of the election (box E).
2. Tax year: in box F and Part II, select the calendar year unless you have a business purpose for a fiscal year. Most small businesses use the calendar year.
3. Officer details: give the name, title and phone number of an officer or legal representative the IRS can contact.
4. Shareholder consents (columns J through N): list every shareholder, their address, shares or ownership percentage, date acquired, SSN or EIN, and tax year end. Each shareholder signs and dates the consent.
5. Late election statement: if you are filing late, write "Filed Pursuant to Rev. Proc. 2013-30" at the top and give the reasonable cause explanation in the space provided.
6. Officer signature: an authorized officer signs under penalties of perjury.
7. Send it: mail or fax it to the IRS address for your state listed in the instructions. Keep a copy, the fax confirmation or certified mail receipt.
8. Wait for the CP261 notice: the IRS acceptance letter confirms the effective date. File it with your formation documents.

What is reasonable salary for an S corp owner?

Reasonable compensation is the part of an S corp election most owners underestimate. The IRS expects shareholder-employees who provide services to take a salary that is reasonable for the work they do before taking distributions. There is no fixed percentage in the law. Factors the IRS and courts look at include:

• Your training, experience, duties and time spent on the business.
• What comparable businesses pay for similar services, often checked against wage data such as the Bureau of Labor Statistics occupational surveys.
• The company's gross receipts, profit and distribution history.
• What you would have to pay a non-owner to do your job.

Paying yourself a very low salary and taking most of the profit as distributions is a well-known audit target. If the IRS reclassifies distributions as wages, the business owes the unpaid payroll taxes plus penalties and interest. The same logic appears in the UK debate over director salary vs dividends.

Worked example: how much can an S corp election save?

Take a graphic designer whose single-member LLC earns $120,000 net profit in 2027. These figures are illustrative and simplified (they ignore the small deduction adjustments in the self-employment tax calculation and state taxes).

Item	Default LLC (Schedule C)	S corp election
Net profit before owner pay	$120,000	$120,000
Owner salary through payroll	None	$65,000
Self-employment tax (about 15.3% on 92.35% of profit)	About $16,950	None
FICA on salary (7.65% employer + 7.65% employee)	None	$9,945
Extra costs: payroll service, 1120-S preparation	None	About $2,500 (illustrative)
Approximate payroll and SE tax plus added costs	About $16,950	About $12,445

In this example the election saves roughly $4,500 a year. At $50,000 of profit, the saving would be much smaller and could disappear once payroll and accounting fees are counted. Income tax also changes slightly, because the qualified business income deduction is calculated differently when part of the profit is wages; our guide to the QBI deduction explains why. For a fuller picture of the rates on each structure, read LLC tax rate explained.

What changes after the election is accepted?

• Payroll: you run payroll for yourself, withhold income tax and FICA, make deposits and file Forms 941 and 940, plus a W-2 each January. Our guide to employer payroll taxes explains each tax you will now pay.
• Annual return: the business files Form 1120-S, due March 15 for calendar-year companies, with a six-month extension available on Form 7004.
• K-1s: each shareholder receives a Schedule K-1 showing their share of income, which flows to their Form 1040.
• Bookkeeping: keep salary, distributions and reimbursements clearly separate. Health insurance for more-than-2% shareholders has special reporting on the W-2.
• State rules: most states follow the federal S election, but some require a separate state election or charge their own entity-level tax.

Your invoicing stays the same: invoices are issued in the business name, and clients pay the business account. If you are not sure what needs to be on them, see how to invoice as an LLC, or build one in our free invoice generator.

Should you elect S corp status now or wait?

Timing matters as much as eligibility. A few practical questions help decide:

• Is profit stable? One strong year followed by a slow one can leave you paying a fixed salary out of thin profits. Many owners wait until profit has been steady for at least a year.
• Can you pay a reasonable salary and still have meaningful profit left? If the reasonable salary for your role takes almost all the profit, the saving is small.
• What does your state charge? Some states impose franchise taxes, minimum taxes or entity-level taxes on S corporations that eat into the federal saving.
• Do you plan to bring in investors? Venture investors usually want a C corporation with preferred stock, which an S corp cannot issue because of the one-class-of-stock rule.
• Are you ready for payroll admin? Monthly or semiweekly deposits, quarterly Form 941 filings and a W-2 for yourself are part of the package.

Electing mid-year is possible for a new entity, but an existing LLC switching on January 1 keeps the books cleaner, because the whole year is reported on one type of return. If you are still deciding on your structure, read how LLCs file taxes first, then revisit the election when the numbers support it.

Common Form 2553 mistakes

• Missing a shareholder consent, including a spouse's consent in a community property state.
• Wrong effective date, such as a date before the entity existed or a date that does not match the tax year chosen.
• Name or EIN mismatch with IRS records, which delays processing.
• Filing too late without requesting relief, which pushes the election to the following year.
• Not starting payroll, then taking only distributions all year.
• Electing too early, when profit is too low for the savings to cover the added costs.

Form 2553 checklist

• EIN confirmed and legal name matches IRS records.
• Eligibility tests met: shareholders, one class of stock, domestic entity.
• Effective date and tax year chosen.
• All shareholder consents signed and dated.
• Filed by the deadline, with proof of filing kept.
• Payroll provider set up before the first salary payment.
• Reasonable salary documented with comparable pay data.
• Calendar entries for Form 1120-S, Form 941 and W-2 deadlines.

Form 2553 is a short form with long-lasting effects, so check eligibility, deadlines and the reasonable salary question before you sign, and talk to a tax professional if the savings are borderline.
