How to Elect S Corp Status for an LLC: Form 2553 Steps and Deadlines

To elect S corp status for an LLC, file Form 2553 with the IRS by the 15th day of the third month of the tax year you want the election to take effect — March 15 for calendar-year businesses. The LLC keeps its state-law identity but is taxed as an S corporation, meaning profits flow through to owners’ personal returns and a portion of income can be taken as distributions instead of salary, cutting the payroll tax bill.

Why the Election Is Worth Making

By default, the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership.¹ Under either classification, all net business income is subject to self-employment tax at a combined rate of 15.3 percent — 12.4 percent for Social Security plus 2.9 percent for Medicare. Once profits climb, that hits hard.

An S corporation splits your income into two buckets. You pay yourself a reasonable salary, which carries the usual payroll taxes. Any remaining profit taken as a distribution is subject to income tax but not Social Security or Medicare tax.² For an LLC earning well above what the owner’s salary alone would justify, the difference can save thousands per year.

Check Eligibility Before You File

Federal law sets hard limits, and failing any one of them kills the election. Under 26 U.S.C. § 1361, an LLC electing S status must be:

Organized in the United States or under the laws of a U.S. state.
Held by 100 or fewer owners. Members of the same family and their estates count as a single shareholder.
Owned only by individuals, certain estates, or qualifying trusts. Other LLCs, partnerships, and corporations cannot hold membership interests.
Free of nonresident alien members. Every owner must be a U.S. citizen or resident alien.
Operating with one class of stock: all members must have identical rights to distributions and liquidation proceeds. Differences in voting rights alone are fine.

The single-class-of-stock rule is where multi-member LLCs stumble. Operating agreements often give different members different distribution percentages, preferred returns, or special allocations. Any of those can look like a second class of stock. Before filing, review the operating agreement and amend it if members’ economic rights aren’t proportional to ownership percentages.

Filing Deadlines

Timing determines whether the election works for the year you want or slides to the next one. Two options exist under 26 U.S.C. § 1362(b):

File on or before the 15th day of the third month of the tax year. For a calendar-year LLC, that’s March 15. If March 15 falls on a weekend, the deadline shifts to the next business day.
File at any time during the preceding tax year. Submitting in November or December for an election effective January 1 of the following year is common and gives more breathing room.

⁴

A filing made after March 15 but before March 15 of the following year is treated as effective for the next tax year, not the current one. So a form sent in June 2026 would take effect January 1, 2027, for a calendar-year entity.

If You Miss the Deadline

Missing March 15 doesn’t always mean waiting a year. Revenue Procedure 2013-30 provides a relief path if you file within three years and 75 days of the intended effective date. You must show that the LLC intended to be an S corporation from the start, that the only failure was a late Form 2553, and that reasonable cause existed for the delay.⁵

A broader exception applies when the LLC and every owner have reported income consistently with S corporation status for the year the election should have been made and every year after. Under that path, the three-year-and-75-day window doesn’t apply, but at least six months must have passed since the first S corporation return was filed, and the IRS must not have raised any issue with the S status during that time.⁵ Either route requires attaching an explanation to Form 2553.

Completing Form 2553

Form 2553 is titled “Election by a Small Business Corporation,” and it’s the only form you need. Many owners assume they have to file Form 8832 first to elect corporate classification and then Form 2553 for S status. That’s wrong. When an eligible LLC files Form 2553, the IRS automatically treats it as a simultaneous election to be classified as a corporation.⁶ The Form 2553 instructions state that an eligible entity meeting the S corporation tests “will be treated as a corporation as of the effective date of the S corporation election and doesn’t need to file Form 8832.”⁷

Enter the LLC’s legal name exactly as it appears on state formation documents, along with the EIN, date of organization, and state of formation. For the effective date, a new LLC enters the earliest of three dates: when it first had owners, first had assets, or first began doing business.⁷ An existing LLC electing for the upcoming tax year enters January 1 of that year.

Every owner must consent individually. List each member’s name, address, SSN or TIN, ownership percentage (LLCs use percentages rather than share counts), and the date ownership was acquired. Each owner signs and dates the form. If a member lives in a community property state and a spouse holds a community property interest in the membership, both spouses must sign.⁷ A missing spousal signature is one of the most common reasons the IRS rejects these filings.

Where to Send It

Two IRS service centers handle Form 2553 based on where the LLC’s principal place of business sits. Eastern states, from Maine down through Georgia and west through Wisconsin, mail to Kansas City, MO 64999. Western and southern states, from Alabama across to California and up through Alaska, mail to Ogden, UT 84201.⁷ The IRS also accepts Form 2553 by fax; numbers are listed in the form instructions and on the IRS website.⁸

Mail by certified mail with return receipt requested. That creates proof of when the IRS received your filing, which matters if a deadline dispute comes up later. Keep a complete copy of the submission.

What Happens After You File

Once the IRS processes the election and approves it, Notice CP261 arrives in the mail confirming S corporation status and the effective date.⁹ Processing generally takes about 60 days, longer during peak filing season. If nothing arrives after eight weeks, call the IRS Business and Specialty Tax Line to check on the application. You need that confirmation before filing the first S corporation return.

Pay Yourself a Reasonable Salary

This is where the IRS pays close attention. An owner who works in the business must be paid a reasonable salary before taking any distributions. Paying yourself $10,000 in salary and pulling $150,000 in distributions to avoid payroll taxes will not survive scrutiny. Courts have reclassified distributions as wages when the salary was unreasonably low, producing back taxes, penalties, and interest.²

The IRS looks at training and experience, actual duties and hours worked, what comparable businesses pay for similar roles, whether distributions pattern above flat salaries, and any formal compensation agreement.¹⁰ A workable test: if you’d have to pay someone that salary to do your job, it’s probably defensible.

New Annual Filings

The election creates obligations that didn’t exist when the LLC was a disregarded entity or partnership. The S corporation files Form 1120-S each year. For calendar-year entities, the due date is March 15, or March 16, 2026, since the 15th falls on a Sunday.¹¹ The return is informational; the S corp doesn’t pay income tax at the entity level. Each owner receives a Schedule K-1 reporting their share of income, deductions, and credits, and carries those figures to their personal return.¹

Because you’re paying yourself a salary, you also take on employer payroll duties: withholding federal income tax and the employee share of Social Security and Medicare, paying the employer share, filing quarterly Form 941, and issuing a W-2 at year end. For a single-owner LLC that used to report everything on Schedule C, this is a real jump in administrative work. Many S corp owners hire a payroll service to handle it.

State Rules Are Separate

The S corporation election is a federal tax classification. Most states follow the federal election automatically, but not all. Some jurisdictions don’t recognize S corp status, some tax S corporations essentially the same as C corporations, some require a separate state-level election, and a few impose minimum franchise taxes or fees on S corporations regardless of income.

Before filing Form 2553, check with the state department of revenue for the state where the LLC operates. Federal S corp status is unaffected by state rules, but ignoring state requirements can produce unexpected tax bills.

Ending the Election Later

S corp status isn’t permanent. Owners holding more than 50 percent of the outstanding ownership interests can voluntarily revoke it by consenting in writing.⁴ The LLC submits a statement of revocation with those signatures to the IRS.¹² A revocation filed on or before March 15 of the tax year takes effect January 1 of that year. Filed after March 15, it takes effect January 1 of the following year unless the revocation specifies a later date.

The election also terminates automatically if the LLC stops qualifying as a small business corporation. Transferring a membership interest to a corporation, admitting a 101st owner, or bringing on a nonresident alien member each triggers immediate loss of status as of the disqualifying event.⁴

After a revocation or termination, the LLC generally cannot re-elect S corporation status for five tax years without IRS consent.⁴ That waiting period is a reason to be careful about who joins the ownership and how membership interests are structured before problems appear.
