Form 2553 Instructions: How to Complete and File It
The short answer
Form 2553 elects S-corporation tax status. Complete Part I, get every shareholder to sign Column K by hand, and mail or fax it to the IRS service center for the state where your business operates — it cannot be e-filed. The deadline is 2 months and 15 days after the start of the tax year you want it to cover, and if you have missed that you can usually still file late under Rev. Proc. 2013-30.
Form 2553, Election by a Small Business Corporation, is how an LLC or corporation tells the IRS it wants to be taxed as an S corporation. Nothing else does this. Forming an LLC does not, checking a box with your state does not, and telling your accountant does not. Until a completed Form 2553 is filed and accepted, there is no S corporation.
The form itself is four pages and is free from irs.gov — see Form 2553 PDF for the blank form itself. The difficulty is not filling in boxes — it is knowing which date belongs on line E, who counts as a shareholder who must consent, and where the form goes. This guide covers each of those; for the submission from start to finish, see how to file Form 2553.
Before you start: is the election worth it?
An S election is not free. It commits you to running payroll, filing Forms 941 and 940, issuing yourself a W-2, and filing a separate Form 1120-S every year. Realistically that is $900 to $2,700 a year in payroll service and extra return preparation.
Below roughly $50,000 of profit, those costs usually exceed the tax saved. There is also an offset most people are not told about: every dollar you pay yourself as salary reduces your Section 199A qualified business income dollar for dollar, and so cuts the deduction by twenty cents, which claws back around a third of the headline saving for most owners.

$5,056
estimated saving per year
The election looks like it saves around $5,056 a year — comfortably more than the payroll and filing costs it creates. Confirm you can support the salary figure and that you are ready for the ongoing filings.
Federal income tax plus employment taxes, plus the added cost of running payroll and a corporate return.
Where the saving actually comes from
- Employment tax you stop paying
- +$8,651
- Extra income tax, mostly from a smaller QBI deduction
- −$2,175
- Payroll service and the extra tax return
- −$1,420
- Net
- $5,056
Most calculators quote 15.3% of your distributions and stop there. They leave out that every dollar of salary also reduces your qualified business income deduction, and that your adjusted gross income moves. Both are included above.
In this model, the lowest total tax lands at a salary of $18,000
That is an observation about the arithmetic, not a recommendation. Reasonable compensation is a facts-based legal standard — what you would have to pay someone else to do your job. Setting salary to whatever minimizes tax is precisely the position the IRS challenges. There is no 60/40 rule, and no percentage safe harbor of any kind.
What an S election commits you to
Running payroll at least quarterly, filing Forms 941 and 940, issuing a W-2, filing a separate Form 1120-S every year, keeping the salary defensible, and — in some states — a separate state election plus entity-level tax. The election also locks in: revoking it generally bars re-electing for five years.

Start my Form 2553Estimates use 2026 federal figures verified on July 30, 2026.

This is self-help information, not tax advice.
Check you are eligible first
An S corporation must meet every one of these tests, and it must keep meeting them. If any is broken, the election is invalid — and if it is broken later, the election terminates.
- It is a domestic entity — formed in the United States.
- It has no more than 100 shareholders. Family members can be counted as one shareholder.
- Every shareholder is an individual, an estate, or a qualifying trust. A partnership, an LLC, or a corporation cannot hold shares.
- No shareholder is a nonresident alien. This trips up businesses with a foreign co-founder more often than any other rule.
- There is only one class of stock. Differences in voting rights are fine; differences in distribution or liquidation rights are not.
- It is not an ineligible corporation — certain financial institutions, insurance companies and domestic international sales corporations cannot elect.
The one-class-of-stock trap for LLCs
Many LLC operating agreements contain a preferred return, a distribution waterfall, or a disproportionate liquidation preference. Any of those can create a second class of stock and make the entity ineligible. If your operating agreement was drafted for an investment structure rather than a simple owner-operated business, have it reviewed before you file.
Part I, page 1 — line by line
| Line | What goes in it | Needed |
|---|---|---|
| NameName of the entity | The exact legal name on file with the IRS for this EIN — the name you used on the SS-4, not a trade name or DBA. Common mistake: Using a DBA or dropping the 'LLC'. A name that does not match IRS records is a common rejection reason. | Always |
| AEmployer identification number | Your nine-digit EIN, formatted 12-3456789. Common mistake: Applying for a new EIN because you are 'becoming an S corp'. You are not forming a new entity, and the existing EIN stays. | Always |
| BDate incorporated | The date the entity was legally formed with the state — the date on your articles of organization or incorporation. | Always |
| CState of incorporation | The state the entity was formed in. Note this is not necessarily the state that determines where you file. Common mistake: Assuming this also decides your filing address. Routing follows your principal business location instead. | Always |
| DName or address changed | Check only if the entity changed its name or address after applying for the EIN shown in item A. | If it applies |
| EEffective date of election | The first day of the tax year the election should take effect. For an existing calendar-year business that is January 1. For a brand-new entity it is the earliest of: the date it first had owners, first had assets, or first began doing business. Common mistake: A new entity entering January 1 when its first tax year actually began mid-year, or entering the formation date when business began earlier. This single box decides whether your election starts when you think it does. | Always |
| FSelected tax year | Almost always box 1, calendar year. Boxes 2 and 4 (fiscal or 52-53 week years) require you to complete Part II as well. | Always |
| GMore than 100 shareholders | Check only if more than 100 shareholders are listed in item J and you are treating family members as one shareholder to get under the limit. | If it applies |
| HOfficer the IRS may call | A name, title and phone number for someone who can answer questions about the filing. | Always |
| IExplanation for a late election | Required only if you are filing late. Must cover both reasonable cause for missing the deadline and the diligent action you took once you discovered it. Common mistake: Explaining only why it was missed. A statement silent on what you did upon discovery is facially deficient under Rev. Proc. 2013-30. | If it applies |
| SignSignature of officer, title and date | An authorized officer or member signs and dates page 1. Common mistake: The IRS did not make the signature and date boxes fillable in the PDF, so people print and forget them. Only 'Title' can be typed. | Sign by hand |
| Line | What goes in it | Needed |
|---|---|---|
| JName and address of each shareholder | Every shareholder required to consent. For a late election this includes anyone who held an interest at any time from the first day of the election year through the filing date — including people who have since sold out. Common mistake: Listing only current owners on a late election. Former shareholders in the look-back period must also sign. | Always |
| KShareholder's consent statement | Each shareholder signs and dates personally. In a community property state, a spouse with a community interest must also consent. Common mistake: Typing names instead of signing. A typed name is not a consent, and a missing consent invalidates the election. | Sign by hand |
| LStock owned and dates acquired | Number of shares or percentage of ownership, plus the date each holding was acquired. Single-member LLCs enter 100%. | Always |
| MSocial security number or EIN | The shareholder's SSN, or EIN for an eligible entity shareholder such as a qualifying trust or estate. | Always |
| NShareholder's tax year end | Month and day the shareholder's own tax year ends — 12/31 for essentially every individual. | Always |
Part II applies only if you selected a fiscal or 52-53 week tax year in item F. Part III is the QSST election, used when a qualifying trust holds shares. Part IV holds the five late corporate classification representations an LLC must make when its election is filed late.
Getting line E right
Line E is the box that decides whether your election starts when you think it does, and it is where most self-filed forms go wrong.
If your business already existed before this tax year
Enter the first day of the tax year you want the election to cover. For a calendar-year business that is January 1. You can file at any time during the preceding tax year, or up to 2 months and 15 days into the year itself.
If this is the entity's first tax year
Enter the earliest of three dates — not the formation date by default:
- 1The date the entity first had shareholders or owners.
- 2The date the entity first had assets.
- 3The date the entity began doing business.
The form itself carries a caution about this: a new entity will usually enter the start of a short tax year beginning on a date other than January 1. If you registered your LLC in March but opened a bank account and started invoicing in February, February is very likely your answer, and your deadline is measured from there.
Filing before your first tax year begins does not work
An entity with no prior tax year cannot elect early. An election filed before its first tax year starts is invalid rather than premature, and the IRS will reject it. Wait until the tax year has begun.
This is the date that goes on line E. For a calendar-year business it is usually January 1.
You are filing early, which is allowed
An entity that already has a prior tax year may elect at any time during the preceding tax year, so filing now for an effective date of January 1, 2027 is valid. The final deadline is March 15, 2027.
- Timely filing deadline
- March 15, 2027
- Late relief closes
- March 16, 2030
- 3 years and 75 days after your effective date, under Rev. Proc. 2013-30.
Page 2 — shareholder consents
Every shareholder must consent, personally, in writing. This is the requirement that most often sinks an otherwise correct filing.
- Signatures must be handwritten. Column K is a consent under penalties of perjury. A typed name is not a consent.
- Page 2 holds only seven shareholders. If you have more, use additional copies of page 2 — the form says so on the page itself.
- Community property spouses must consent too. If you are in Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington or Wisconsin and your spouse has a community interest in the stock, they sign as well.
- Late elections need a wider set of signatures. Everyone who was a shareholder at any time from the first day of the election year through the day you file must sign — including people who have since sold out entirely.
The former-shareholder problem
If a co-founder held 30% during the election year and was bought out afterwards, they still have to sign a late election. If they are unreachable, uncooperative, or deceased with no one authorized to sign for the estate, Rev. Proc. 2013-30 relief is not available. Track people down before you start.
Parts II, III and IV — when they apply
| Part | Complete it when | Most people |
|---|---|---|
| Part II | You selected a fiscal year, or a 52-53 week year referencing a month other than December, in item F. | Skip it |
| Part III | A qualifying trust holds shares and you are making a Qualified Subchapter S Trust election. | Skip it |
| Part IV | You are an LLC filing a late election. A timely Form 2553 makes a deemed entity classification election automatically; a late one does not, so you make five representations here instead. | Only if late |
Do not file Form 8832 as well
If you complete Part IV, you must not also file a separate Form 8832. Representation 3 in Part IV states that no timely Form 8832 was filed — filing one contradicts your own representation and can sink the relief request. This is one of the most common do-it-yourself mistakes.
Where to send Form 2553
Form 2553 cannot be e-filed. It goes by mail or fax to one of two IRS service centers, chosen by where your business actually operates — its principal business, office or agency. Not where it was incorporated. A Delaware LLC run from Ohio files as an Ohio business. For the addresses themselves, see where to mail Form 2553.

Form 2553 cannot be e-filed. Mail or fax is the only way to submit it.
If you have already missed the deadline
Filing late does not void the form, and this surprises people. Under IRC §1362(b)(3), an election filed after the deadline is simply treated as an election for the following tax year. You will not be rejected; you will quietly get a different start date than the one you wanted.
To keep your original date, request relief under Rev. Proc. 2013-30. You generally qualify if you intended to be an S corporation from the effective date, the only thing that went wrong was the missed filing, everyone has reported income consistently, and you are within 3 years and 75 days of the effective date.
A late filing needs three things the timely version does not: the words FILED PURSUANT TO REV. PROC. 2013-30. written across the top margin of page 1, an explanation on line I covering both reasonable cause and the diligent action you took on discovering the problem, and consent signatures from the wider look-back group. See our late election guide for the full conditions.
After you file
1Keep your proof of filing
A fax transmission report or a certified mail return receipt is the only thing that establishes your filing date. Scan it and keep it permanently.
2Watch for Notice CP261
This is the acceptance notice. The IRS says to expect a determination in about 60 days, though it does not publish a live processing estimate for this form — see Form 2553 processing time for what happens after you file. Keep the notice — you will need it to open payroll accounts.
3Chase it if nothing arrives
After 60 days with no response, call the IRS Business and Specialty Tax Line on 800-829-4933 with your proof of filing to hand.
4Start payroll
The election means nothing in practice until you actually pay yourself a reasonable salary through payroll, with withholding and quarterly filings.
The four mistakes that cause most rejections
- 1A missing or typed shareholder consent. Every shareholder signs Column K by hand.
- 2A name that does not match IRS records. Use the exact legal name associated with your EIN, not a trade name.
- 3The wrong date on line E, usually a new entity entering January 1 when its first tax year began mid-year.
- 4Sending it to the wrong service center, almost always because routing was based on the state of incorporation rather than where the business operates.

Start my Form 2553Frequently asked questions
Can Form 2553 be filed electronically?
No. As of 2026 Form 2553 must be mailed or faxed to the IRS. The only electronic route is attaching a late election as a PDF named Form2553.pdf to a timely e-filed Form 1120-S, which is an attachment to a return rather than e-filing the election itself.
Can Form 2553 be signed electronically?
The shareholder consents in Column K and the officer signature on page 1 are declarations under penalties of perjury. The safest approach, and the one Scorply generates for, is printing the form and signing by hand in ink. The IRS did not make those boxes fillable in its own PDF.
How long does the IRS take to process Form 2553?
The instructions say to expect a determination within about 60 days. The IRS does not currently publish a live processing-time estimate for Form 2553 — the form is absent from its processing status page — so treat 60 days as the stated expectation rather than a promise. If you have heard nothing after that, call 800-829-4933.
Do I need a new EIN to become an S corporation?
No. Electing S-corporation status changes how an existing entity is taxed; it does not create a new entity. Keep your existing EIN and enter it in item A.
What happens if a shareholder refuses to sign?
The election cannot be made. Consent from every required shareholder is a statutory requirement, not a formality, and no amount of relief fixes a genuinely withheld signature. The one narrow exception is a missing community property spouse's consent, which has its own automatic relief under Rev. Proc. 2004-35.
Do I file Form 2553 every year?
No. The election is made once and continues until it is revoked or terminated. What you do file every year afterwards is Form 1120-S, plus payroll returns.
