How to File Form 2553 for an LLC: Step-by-Step S Corp Election Guide (2026)

Filing Form 2553 is the single step that tells the IRS your LLC wants to be taxed as an S corporation. The form is short, the IRS charges nothing to file it, and most owners can finish it in under an hour. The hard part is timing. Miss the window and you may owe self-employment tax you hoped to avoid, or end up filing a late-election request.

This guide covers how to file Form 2553 for an LLC from start to finish: who qualifies, what to gather, how to complete each part of the form, where to send it, and what happens afterward. It is procedural by design. If you are still deciding whether an S corp election makes sense, read our LLC vs S-Corp comparison first, then come back here to file.

You also need an active LLC with an EIN before you can file. If you haven’t formed yet, a service like ZenBusiness can handle the state filing and EIN. Its entry-level plan has historically started at $0 plus your state’s filing fee, and paid tiers add extras such as an operating agreement and compliance monitoring. Pricing changes often, so confirm current plans on our ZenBusiness review page. Once the LLC exists, the S corp election is a separate IRS filing that you make yourself.

What Form 2553 Does (and Doesn’t) Do

Form 2553, Election by a Small Business Corporation, is an IRS form. It does not create a new legal entity, change your LLC’s state registration, or alter your liability protection. Your LLC stays an LLC under state law. Form 2553 only changes how the IRS taxes it.

By default, the IRS taxes a single-member LLC as a “disregarded entity” (you report income on Schedule C) and a multi-member LLC as a partnership. After a valid S corp election, the LLC files its own return (Form 1120-S). Profits pass through to the owners’ personal returns, but the owners who work in the business must be paid a reasonable salary through payroll. The remaining profit can be taken as distributions that are not subject to self-employment tax.

One technical point that saves paperwork: an eligible LLC that timely files Form 2553 is treated as having elected to be taxed as a corporation. The IRS says this in the form instructions, so you generally don’t need to file Form 8832 first. You can read the official Form 2553 instructions on IRS.gov.

Check Eligibility Before You File

The IRS rejects elections from entities that don’t qualify, and a rejected election can leave you with the wrong tax treatment for a full year. Before you start, confirm that your LLC meets every requirement:

It is a domestic entity. It must be organized in the United States.
It has 100 or fewer owners. Family members can be treated as one owner for this count.
Every owner is an eligible shareholder. That means individuals who are U.S. citizens or residents, certain trusts, and estates. Nonresident aliens, partnerships, and corporations can’t be S corp owners.
It has only one class of stock. For an LLC, that means distributions must match ownership percentages. A 60/40 LLC cannot routinely distribute 50/50.
It isn’t an ineligible business type. Certain financial institutions and insurance companies can’t elect S status.

The one-class-of-stock rule trips up more LLCs than any other. In my experience, owners who drafted a custom operating agreement years ago often discover it gives one member a preferred return or a different profit split. Either can be treated as a second class of stock. If that sounds familiar, have an attorney review the agreement before you file. Our LLC operating agreement guide explains what S-corp-friendly language looks like.

The Form 2553 Deadline

The Form 2553 deadline is the part most owners get wrong, so here is the rule exactly.

You must file no more than 2 months and 15 days after the beginning of the tax year the election takes effect. You can also file at any time during the tax year before the one you want it to apply to.

Calendar-year LLC, existing business: For an election effective January 1, 2027, you can file any time in 2026, up to and including March 15, 2027. (For the 2026 tax year, the equivalent date was March 16, 2026, because March 15 fell on a Sunday.)
Brand-new LLC: The 2-month-15-day clock starts on the earliest of three dates: when the LLC first has owners, when it acquires assets, or when it begins doing business. An LLC that starts operating on April 10 has until June 24 to file.

Because it is October 2026, an existing LLC that wants S status for all of 2027 has plenty of time. File this year and you remove the March 15 pressure entirely.

What if you missed it?

The IRS offers late-election relief under Revenue Procedure 2013-30. It generally requires that you file within 3 years and 75 days of the intended effective date, that you had reasonable cause for the delay, and that you and all owners reported income consistently with S corp treatment. You write “FILED PURSUANT TO REV. PROC. 2013-30” at the top of Form 2553 and attach a reasonable-cause statement. This is a common fix, but I would involve a CPA before relying on it.

What to Gather Before You Start

Pulling this information together first prevents the half-finished form that sits in a drawer for three weeks:

Legal LLC name and address. These must match your state filing and IRS records exactly.
EIN. If you don’t have one, get it first. Our free EIN walkthrough covers the IRS method.
State and date of formation. Use the date on your Articles of Organization.
Desired effective date. Typically January 1 for an existing business, or the start date for a new one.
Each owner’s name, address, and Social Security number.
Ownership details. For each owner, that means the number of shares or ownership percentage and the date acquired.
Tax year. Most LLCs use a calendar year (ending December 31).
Signatures. Every owner must sign the consent column, and an authorized person must sign the form itself.

How to File Form 2553 for an LLC, Step by Step

These are the Form 2553 instructions in plain English. Use the current revision of the form from IRS.gov, since the IRS updates layouts periodically.

Step 1: Complete Part I, the election information

Name, address, and EIN. Enter them exactly as they appear on your EIN confirmation letter (CP 575 or 147C).
Date and state of incorporation. For an LLC, enter your formation date and state.
Effective date of election. Enter the date you want S status to begin. For a calendar-year LLC electing for 2027, that is 01/01/2027.
Tax year. Most LLCs check the calendar year. Choosing anything else requires Part II and extra IRS approval, which rarely makes sense for a small business.
Name and title of a signing officer. For an LLC, this is a member or manager with authority.

Step 2: List every owner and collect consents

For each owner, enter the name, address, number of shares or ownership percentage, date acquired, and tax ID number. Each owner then signs and dates the consent column.

A spouse who has a community property interest in the shares must also consent in community property states. Skipping this is a classic reason for IRS rejection.

Step 3: Sign and date the form

The authorized person signs under penalties of perjury. If you are filing alongside a tax professional, they may also sign as preparer.

Step 4: Skip Parts II and III unless they apply

Part II covers fiscal-year elections. Part III covers certain trust and ownership situations. Most calendar-year LLCs leave both blank.

Step 5: File it with the IRS

The form instructions list the filing address or fax number for your state, and the destination depends on where your LLC’s principal business is located. Check the current instructions before sending, since the IRS has changed service center assignments in the past.

Two practical tips:

Fax is usually the fastest option. Keep the fax confirmation page as proof of the filing date.
If you mail it, use certified mail with return receipt. The postmark date is your proof of timely filing.

There is no IRS filing fee. Anyone charging you a “fee” is charging for their own service, not the government’s.

What Happens After You File

The IRS typically processes the form and mails a CP261 notice accepting the election. The agency tells filers to allow roughly 60 days. If you haven’t heard back after that, call the IRS business line and ask for the status. Keep the acceptance letter permanently. Banks, lenders, and future accountants will ask for it.

Once accepted, your to-do list changes:

Run payroll for yourself. Working owners must receive a reasonable salary with normal payroll withholding. Our guide to reasonable salary for S corp LLC owners shows how to set the number.
File Form 1120-S annually. It is due the 15th day of the third month after year-end (March 15 for calendar-year entities). Form 7004 gives a six-month extension.
Issue Schedule K-1s to each owner.
Keep distributions pro rata so you don’t create a second class of stock.
Check your state rules. Some states layer their own taxes on S corps. California, for example, charges a 1.5% tax on S corp net income with an $800 minimum, and New York City does not recognize S status for its own business taxes.

A Quick Worked Example

Suppose Maria runs a single-member consulting LLC that nets $120,000 a year. As a default disregarded entity, her whole profit is subject to roughly 15.3% self-employment tax (up to the Social Security wage cap), plus income tax.

After a valid S election, she might pay herself a reasonable salary of, say, $70,000 and take the other $50,000 as a distribution. Self-employment-style payroll taxes then apply to the $70,000 salary only. The savings can be meaningful, but payroll software, a separate business return, and possible state taxes also cost real money, often several thousand dollars a year in total. This is purely an illustration, not a prediction of your results. Many owners find the break-even point lands somewhere in the range of $50,000 to $80,000 or more in net profit, though it varies by state and situation. The 20% qualified business income deduction, which the 2025 federal tax law made permanent, also interacts with your salary and distribution mix, so run the numbers with a CPA.

Common Mistakes That Get Elections Rejected

Missing owner signatures or a missing spouse consent.
Mismatched names or EINs. Even small differences from your IRS records can delay processing.
Filing before the LLC has an EIN. The form needs one.
Having an ineligible owner, such as a nonresident alien or another LLC taxed as a partnership.
Ignoring the deadline and assuming the IRS will forgive a late filing automatically. It won’t.

Should You File It Yourself or Use a Service?

You can complete Form 2553 on your own at no cost, and the process above is genuinely manageable for a straightforward LLC. Hire a CPA or tax attorney if you have multiple owners with unequal economics, owners in community property states, a trust as an owner, or a late election to fix.

If your LLC doesn’t exist yet, I’d form it first through a provider rather than juggling both processes at once. ZenBusiness is my default pick for first-time owners because the formation and EIN steps are streamlined. LegalZoom is a reasonable alternative if you want its broader legal-document ecosystem, though its tiers generally cost more than ZenBusiness for comparable features. For a side-by-side look at both, see our best LLC services comparison. Whichever you choose, confirm whether the provider offers any S corp election help, and compare that price against doing it yourself for free.

Frequently Asked Questions

How much does it cost to file Form 2553?

The IRS charges no fee to file Form 2553. Costs only arise if you hire a CPA, attorney, or formation service to prepare it, and those fees vary widely. Check any provider’s current price before agreeing.

Do I need to file Form 8832 before Form 2553?

Usually not. An eligible LLC that timely files Form 2553 is treated as electing corporate classification and S status at the same time, according to the IRS instructions. A separate Form 8832 is generally unnecessary.

Can I file Form 2553 online?

The IRS has historically accepted Form 2553 by mail or fax, not through a general e-file system. Check the IRS’s current instructions for your options, because procedures can change.

What happens if I miss the Form 2553 deadline?

You may qualify for late-election relief under Revenue Procedure 2013-30 if you have reasonable cause and meet the consistency requirements. Without relief, the LLC keeps its default tax classification for that year, and the election would start at the next eligible date.

How long does it take the IRS to approve Form 2553?

The IRS generally asks filers to allow about 60 days before following up. You’ll receive a CP261 acceptance notice by mail once the election is approved.

Can I revoke an S corp election later?

Yes, but revocation has rules and consequences. Generally, owners holding more than half the shares must consent, and a company that terminates S status typically can’t re-elect for five years without IRS consent. Talk to a tax professional first.

Does an S corp election change my LLC’s liability protection?

No. Liability protection comes from your state’s LLC law and from how you run the business, such as keeping personal and business finances separate. Form 2553 only changes federal tax treatment.

Do I need an operating agreement to file Form 2553?

The IRS doesn’t ask you to submit it. But your operating agreement must support S corp requirements, particularly pro-rata distributions, or you could jeopardize the election later.

Final Thoughts

Learning how to file Form 2553 for an LLC is mostly about preparation: confirm eligibility, respect the deadline, collect every signature, and keep proof of filing. If your LLC is already profitable and you want S status for 2027, filing before the end of this year takes the deadline pressure off. Pair the election with a realistic payroll plan and a CPA who will keep your Form 1120-S on schedule, and you’ll have turned a one-page form into a durable tax strategy.
