A single member LLC can elect S corporation tax treatment by filing IRS Form 2553, which keeps the LLC intact under state law but changes how the IRS taxes its profits. The point of the single member LLC S corp election is to split your earnings into a reasonable salary and a distribution, so the distribution portion escapes the 15.3% self-employment tax you’d otherwise owe on every dollar of net profit. It’s a real tax savings for many owners, and a real administrative burden for all of them.
What the Election Actually Changes
By default, the IRS treats a single member LLC as a disregarded entity. Income and expenses land on your personal return, usually on Schedule C, and every dollar of net profit is hit with self-employment tax at 15.3%, covering Social Security (12.4%) and Medicare (2.9%).1Internal Revenue Service. Single Member Limited Liability Companies2Internal Revenue Service. Publication 15-A, Employers Supplemental Tax Guide (2026) On $100,000 of profit, that’s roughly $15,300 before any income tax.
An S corporation is a tax classification, not a separate legal entity. Your LLC stays an LLC. But once the election takes effect, you become an employee of the business. You pay yourself a salary, and payroll taxes apply to that salary only. Any profit left after your salary passes through as a distribution, which you report on your personal return and pay income tax on, but which is not subject to Social Security or Medicare tax.3Internal Revenue Service.

The savings come from that distribution portion. If your LLC nets $120,000 and you pay yourself a $60,000 salary, payroll taxes apply to the $60,000 rather than the full $120,000. Compared to owing self-employment tax on the entire profit as a disregarded entity, that’s roughly $9,000 less in payroll-type taxes for the year. The exact number depends on your salary and other facts.
When the Election Pays Off
Running an S corp is more expensive than running a disregarded entity. Payroll processing, the annual Form 1120-S, and heavier bookkeeping typically add $1,000 to $3,000 per year in accounting costs. The self-employment tax savings have to clear that hurdle before you’re actually ahead.
As a rough benchmark, most tax professionals suggest the election starts making sense once your LLC’s net profit consistently exceeds $40,000 to $50,000. Below that, compliance costs eat the savings. Above $80,000 to $100,000, the math usually favors electing without much debate.
Two other factors change the calculus. If you run a service business, meaning your revenue comes almost entirely from your personal work as a consultant, freelancer, or professional, the IRS expects most of the income to be classified as salary, which caps how much you can shift into tax-favored distributions. And if you plan to bring on a corporate partner, a foreign investor, or more than 100 owners, S corp status won’t accommodate that, because shareholders must be individuals or certain trusts and estates, and only one class of ownership is allowed.4Internal Revenue Service.

How to File Form 2553
The election is simpler than most people expect. You do not need to file Form 8832 first. When an LLC files a timely Form 2553, the IRS treats it as a deemed election to be classified as a corporation, so Form 2553 alone handles both steps.5Internal Revenue Service. Entities 3 This detail trips up business owners and some preparers who assume two filings are required.
The form asks for the LLC’s legal name, EIN, date of formation, state of organization, and the tax year you want the election to take effect. Even as a solo owner, you fill out the shareholder section with your own name, address, Social Security number, and 100% ownership.6Internal Revenue Service.

The Deadline
Form 2553 must be filed no later than two months and 15 days after the start of the tax year you want the election to cover, or at any point in the preceding tax year.7Office of the Law Revision Counsel. 26 USC 1362 – Election; Revocation; Termination For a calendar-year LLC, that means filing by March 15 to have the election apply to the current year. Miss that date and the election generally takes effect the following year.
Late Election Relief
If you missed the deadline, you may still get retroactive status under Revenue Procedure 2013-30. Relief is available without a private letter ruling when all of these are true: the entity intended to be an S corporation as of the effective date, the only reason it failed to qualify was the missed filing, you and the business have reported income consistently with S corp treatment for the intended year and every year since, and you file the late Form 2553 within three years and 75 days of the desired effective date.8Internal Revenue Service. Revenue Procedure 2013-30
Write “FILED PURSUANT TO REV. PROC. 2013-30” across the top of the late form and attach a reasonable cause statement explaining why it was late. Reliance on a tax professional who failed to file, or simply not knowing the election existed, are commonly accepted reasons. Past the three-year-and-75-day window, a separate path exists through a private letter ruling under Section 1362(b)(5), but it’s more expensive and slower.7Office of the Law Revision Counsel. 26 USC 1362 – Election; Revocation; Termination
The Reasonable Salary Rule
This is where the election most often goes wrong. Any shareholder who performs services for an S corp must be paid reasonable compensation as W-2 wages before taking distributions.3Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers You cannot pay yourself a token $10,000 salary and pull $150,000 in distributions. Courts have consistently held that owner-employees who provide more than minor services owe employment taxes on appropriate compensation, even when they tried to relabel wages as distributions.
The IRS weighs several factors when judging what’s reasonable:
- Your training, credentials, and experience in the field.
- The duties you perform and the time you devote to the business.
- What comparable businesses pay for comparable work, which is the strongest benchmark.
- Whether the business’s income comes primarily from your personal services, which pushes more of the profit toward the salary side.
- Whether large distributions are paired with a suspiciously small salary.
Set the salary too low and the IRS can reclassify distributions as wages, adding back payroll taxes with penalties and interest. Set it too high and you’ve erased the tax savings that motivated the election.
What You Take On After Electing
Because you become an employee of your own business, the LLC has to run payroll. That means withholding federal income tax, Social Security, and Medicare from your paychecks and paying the employer’s matching share. The recurring filings are Form 941 quarterly (or Form 944 annually if your total payroll tax liability is $1,000 or less), Form 940 annually for federal unemployment, and Form W-2 issued to you by January 31.10Internal Revenue Service. Forms 940, 941, 944 and 1040 (Sch H) Employment Taxes Employment tax deposits must be made electronically.
The S corp files its own return on Form 1120-S. For calendar-year filers, the 2026 return is due March 16, 2026, because March 15 falls on a Sunday.11Internal Revenue Service. Instructions for Form 1120-S The S corp also issues you a Schedule K-1 showing your share of income and deductions, which you carry to your personal return.12Internal Revenue Service. About Form 1120-S, US Income Tax Return for an S Corporation A late or inaccurate K-1 can trigger a $340 penalty per form.
Your salary has taxes withheld, but distributions do not. If withholding falls short of your total liability, quarterly estimated payments are due on your personal return on April 15, June 15, September 15, and January 15 of the following year.13Internal Revenue Service. 2026 Form 1040-ES A useful workaround is to increase your salary withholding to cover the tax on distributions, since wage withholding is treated as paid evenly across the year regardless of when it was actually withheld.
Health Insurance Handling
As a greater-than-2% shareholder, which you are as the sole owner, health insurance the S corp pays on your behalf gets specific tax treatment. The corporation deducts the premiums but must include them as wages on your W-2. Those premiums are not subject to Social Security or Medicare tax, and you take an above-the-line deduction for the full amount on your personal return. The S corp must either pay the premiums directly or reimburse you, and the premiums must appear on the W-2 for the deduction to work. If you or your spouse is eligible for a subsidized plan through another employer, the above-the-line deduction is lost. A greater-than-2% shareholder also cannot participate in a Qualified Small Employer Health Reimbursement Arrangement.9Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues
State Treatment Doesn’t Always Follow
Federal S corp status doesn’t automatically carry over to your state. Louisiana, New Hampshire, Tennessee, Texas, and the District of Columbia do not recognize the S corporation election and tax S corps like C corporations at the state level. New York and New Jersey require a separate state election filing. Most states follow the federal election automatically, but many impose a minimum franchise tax or entity-level fee that applies regardless of profit, ranging from nothing in some states to $800 or more in others. An election that saves $8,000 federally but triggers a $1,600 state entity tax in a jurisdiction that doesn’t fully honor the pass-through may not deliver the net savings you expected. Check your state’s rules before you file.
Reversing the Election
If S corp treatment stops making sense, you can revoke it. Revocation is a written statement to the IRS service center where you file your annual return, including the corporation’s name, EIN, and the effective date of the revocation, signed by shareholders owning more than 50% of the stock, which is just you.14Internal Revenue Service. Revoking a Subchapter S Election Filing by the 15th day of the third month makes the revocation effective on the first day of the current tax year; file later and it takes effect the following year unless you specify a mid-year date. Once revoked, the business generally cannot re-elect S corp status for five years without IRS consent.7Office of the Law Revision Counsel. 26 USC 1362 – Election; Revocation; Termination
Every business’s numbers are different. Modeling your specific profit, salary, and state costs with a tax professional before you file Form 2553 is the most reliable way to know whether the election is worth it for you.
