An LLC and an S corp are not the same kind of thing. An LLC is a business you form with your state. An S corp is a tax status you ask the IRS for, and an LLC can choose it. It usually only pays off once your profit is high enough that the self-employment tax saved is more than the extra payroll and tax-filing costs.
How the S corp saving works
By default, LLC owners pay self-employment tax of 15.3% on their net earnings, per the IRS page on self-employment tax. With S corp tax treatment, you pay yourself a salary through payroll and pay Social Security and Medicare tax on that salary. Profit left over after the salary can be paid out as a distribution, and no Social Security or Medicare tax is due on that part.
The catch: the salary must be reasonable for the work you do. The IRS page on S corporation shareholder pay says an S corp must pay a shareholder who works in the business a reasonable salary before taking distributions. You can’t pay yourself $0 and take everything as a distribution.
A simple example
Say your one-owner LLC has $80,000 of profit in 2026. These are round numbers to show the idea, not a tax calculation.
| Default LLC | LLC taxed as an S corp, $45,000 salary | |
|---|---|---|
| What is taxed for Social Security and Medicare | $80,000 × 92.35% = $73,880 | $45,000 salary |
| Rate | 15.3% | 15.3% (7.65% paid by the business, 7.65% withheld from you) |
| Social Security and Medicare tax | about $11,304 | about $6,885 |
| Difference | about $4,419 less, before extra costs |
From that saving, take off the extra costs: a payroll service, a separate S corp tax return (Form 1120-S), and in some states extra state tax or fees. Income tax still applies to all of your profit either way.
Rules for S corp status
- File IRS Form 2553. Per the IRS Form 2553 instructions, it is due no more than 2 months and 15 days after the start of the tax year you want it to apply to, or any time in the year before.
- Per the IRS page on S corporations, you can have no more than 100 shareholders and only one class of stock. Owners must be individuals, certain trusts or estates. Partnerships, corporations and nonresident aliens can’t be owners.
- Your LLC still exists under state law. Only the federal tax treatment changes.
When it is usually too early
If your profit is small or uneven, the payroll and filing costs can eat the saving. Many first-year businesses wait until profit is steady. Ask a tax pro to run your own numbers.

FAQ
Is an S corp better than an LLC?
They are not either-or. An LLC can be taxed as an S corp. The question is whether S corp tax treatment saves you more than it costs.
What is a reasonable salary?
Roughly what you would have to pay someone else to do your job. The IRS looks at your duties, time spent and what similar businesses pay.
Can a single-member LLC be an S corp?
Yes. A one-owner LLC can file Form 2553 to be taxed as an S corp.
Do I still pay income tax on distributions?
Yes. S corp profit passes through to your personal return and is subject to income tax, whether you take it as salary or distributions.
