Even when you’re a one-person business, tax and legal matters are inevitable. And when it’s all you, you’re the one who has to handle them. The information floating around can make it all seem complicated and intimidating, but it doesn’t have to be.
The Difference between LLC and S Corp
An LLC and an S Corp aren’t opposing options. They work together, with one handling the legal side of your business and the other handling how it’s taxed.
- An LLC, or Limited Liability Company, is a legal structure for a business that separates your personal and business assets and protects your personal assets from business liabilities.
- An S Corp, or S Corporation, is a tax election, not a legal structure, for a business that determines how it is taxed at the federal and state levels.
The short version: Every situation is different, and the right setup depends on your own circumstances and your goals for the business. Forming an LLC gives you liability protection but doesn’t change your federal taxes on its own. Electing S Corp tax status generally makes sense when two things line up. First, you plan to be self-employed for the long term, since the election adds annual reporting requirements. Second, your profit creates a real savings opportunity. That usually happens around $60,000 to $80,000 in profit, where potential savings outweigh the extra admin cost.
As a Business-of-One, you’ve probably heard the terms “LLC” and “S Corp” a ton. You’ve probably heard them used incorrectly a ton, too. There’s a lot of confusion among new business owners around business entities, so it’s worth getting this distinction straight.
Why business structure matters
When you work as a solo operator, you are the business. There’s no distinction. That means you pay personal taxes on everything your business earns. Your personal assets could also be fair game if someone sues you or you owe debts.
As your business grows, formalizing it as a legal structure could help. It lets you take advantage of the liability protection and tax benefits that come with separating yourself from your business. The legal structure is the first step to doing that.
Sole proprietorship is the most common structure for small businesses, largely because it’s the default when you haven’t set anything up. An LLC is a popular next step, and other options include partnership or corporation. To set up an LLC, you first choose a business name and file paperwork with the state. That establishes your business as a separate legal entity. See our guide on how to start an LLC for all 50 states.
By default, the IRS taxes a single-member LLC (SMLLC), an LLC with one owner (you), like a sole proprietorship. That’s the same tax treatment you’d get if you hadn’t formally organized the business, and it has some drawbacks as your profit grows. To lighten your tax load, you can ask the IRS to tax your LLC as an S Corp. This election, under Subchapter S of the tax code, changes how you pay taxes on different parts of your income. Depending on your situation, it could lower your tax bill.
S Corp vs. LLC taxes
By default, an SMLLC pays self-employment tax on nearly all of its profit. With an S Corp election, payroll tax applies to your salary instead, and the remaining profit isn’t subject to payroll tax.
How a default SMLLC is taxed
The IRS assigns every business structure a default tax treatment, which determines how your business is taxed. The IRS treats a single-member LLC as a sole proprietorship. That means you pay self-employment tax on your business profit, plus personal income tax based on your tax bracket.
Self-employment tax (sometimes called SECA tax) is how self-employed people pay into Social Security and Medicare, covering both the employee and employer shares that a traditional job would split. The rate is 15.3%, and it applies to 92.35% of your net earnings from self-employment. It has two parts:
- Social Security (12.4%), which applies up to an annual cap called the Social Security wage base. For 2026, that cap is $184,500.
- Medicare (2.9%), which has no cap. An additional 0.9% Medicare tax applies once earnings pass certain thresholds.
You can deduct half of your self-employment tax when calculating your income tax, which softens the impact somewhat.
How an LLC taxed as an S Corp is taxed
A single-member LLC taxed as an S Corp splits up that income and tax burden. As an S Corp owner, you pay yourself a salary, which has to be “reasonable compensation,” similar to what you’d make as an employee performing the same job.
Your salary is subject to FICA payroll tax, the same Social Security and Medicare tax that applies to any employee’s wages. You personally pay half, 7.65%, through withholding from your paycheck, plus personal income taxes on that salary. Your business pays the other 7.65%, plus federal unemployment tax (FUTA) and state unemployment tax, and can write those off as business expenses.
The rest of the company’s profit passes through to you. It’s subject to income tax but not payroll tax, whether you leave it in the business or take it out.
Taking it out is where distributions come in. Distributions are money that you take out of your business personally, by cutting yourself a check or transferring money to your personal account. They’re how you access your profit, not what determines how that profit is taxed.
An example at $120,000 in profit
This may sound a little complicated, so here’s an example to clear the air. Say you earn $140,000 in revenue this year, with $20,000 in business expenses. That’s $120,000 in profit (congrats!). As a sole proprietor, you pay self-employment tax on the full $120,000, plus personal income tax on $120,000 minus personal deductions or adjustments.
As an S Corp, say your reasonable salary is $45,000. You pay payroll taxes on that $45,000, and the remaining $75,000 passes through to you, which you can take as distributions. You still pay personal income tax on the full $120,000, minus personal deductions or adjustments.
How the numbers compare
Here’s an example of how self-employment tax changes with an S Corp election:
| LLC | S Corp | |
|---|---|---|
| Business Profit | $120,000 | $120,000 |
| Owner Wages | N/A | $45,000 |
| Owner Distribution | $120,000 | $75,000 |
| Subject to Self-Employment or Payroll Taxes (15.3%) | $120,000 | $45,000 |
| Self-Employment or Payroll Tax | $18,360 | $6,885 |
| Potential Tax Savings | $11,475 |
Simplified, illustrative example using 2026 rules. The IRS technically calculates self-employment tax on 92.35% of net earnings, and the business can deduct its share of payroll tax. Actual figures will be somewhat lower. The $45,000 salary is illustrative. A reasonable salary reflects what your role would pay an employee, not a set percentage of profit. Figures exclude income tax, unemployment taxes, state-level taxes and fees, and the cost of running payroll and filing an S Corp tax return. Other examples on our site may use different salary assumptions, so figures can differ from article to article. Actual results will vary.
In this example, the S Corp election could reduce self-employment and payroll taxes by about $11,475 for the year. Whether that turns into real savings depends on your situation. The cost of running an S Corp, including payroll, monthly books, and a separate business tax return, comes out of that difference. Those costs also repeat every year.

The calculator estimates the potential difference in self-employment and payroll taxes. It doesn’t estimate income tax or the QBI deduction, so treat the result as a starting point rather than your full tax picture.
Why would you choose an S Corporation?
Electing S Corp taxation could help reduce your self-employment tax cost if your profit is well above a reasonable salary. That’s because payroll tax applies to your salary instead of nearly all of your profit. How much that matters depends on your business and where you want to take it.
If you’ve been working for yourself for a while, you’ve probably felt the burn of the self-employment tax. It’s a surprise to a lot of new business owners, and it’s why taxes can feel like such a burden when you’re self-employed versus an employee.
S Corps are also a pass-through tax structure, so you may still be eligible for the Qualified Business Income (QBI) deduction. One nuance: your W-2 salary doesn’t count as qualified business income, so the deduction can be smaller than it would be under a sole proprietorship at the same profit.
The disadvantages of an S Corp
Compared with continuing to work for yourself as a sole proprietor, an S Corp can be more complex, and that complexity comes back every year. It’s a big reason the election tends to fit best when you plan to be self-employed for the long term.
- Payroll. You pay yourself a regular paycheck through a formal payroll system and withhold payroll taxes throughout the year.
- A business tax return. The S Corp files its own return (Form 1120-S) and issues you a Schedule K-1 showing your share of the profit. You still file your personal return, too.
- Payroll filings. These include quarterly federal payroll returns (Form 941), an annual federal unemployment return (Form 940), and a W-2 for yourself, sent to the government with a W-3.
- Estimated taxes. The S Corp generally doesn’t make federal estimated tax payments itself. You make personal estimated payments on the profit that passes through to you.
Each state’s treatment of S Corps also varies, so it’s worth considering how your state handles the election as part of your decision. You’ll probably want to enlist the help of a lawyer and accountant once your business is ready for this structure.
Which is better, an LLC or S Corp?
LLCs and S Corps provide different and sometimes complementary benefits to your company, so the better fit depends on your situation.
- Forming an LLC gives legal protection to your personal assets and doesn’t change your federal tax treatment compared with operating as an individual or independent contractor.
- Electing S Corp taxation could reduce the amount of income you pay payroll-type taxes on.
Should your LLC be an S Corp?
Every situation is different, and the answer depends on your own circumstances and your goals for the business. Generally, the election makes sense when you plan to be self-employed long term and your profit creates a savings opportunity. That’s usually around $60,000 to $80,000 in profit, where the potential savings are more than the cost of the extra admin.
The IRS doesn’t set an income threshold, and a lot depends on how much you pay yourself as a salary. Figure out what your reasonable compensation would be first. If it’s less than your total profit, you could save on federal payroll taxes by electing S Corp status. For a closer look at the numbers, see our S Corp breakeven table.
FAQs about LLC vs. S Corp
Business legal and tax terms are confusing. So let’s clear up a few common questions to help you determine whether to elect S Corp status for your LLC. For even more, our S Corp FAQ covers the questions solopreneurs ask most.
Who pays more taxes, an LLC or S Corp?
It depends on your situation. Typically, an LLC taxed as a sole proprietorship pays more in payroll-type taxes once its profit is well above a reasonable salary. S Corp tax status can mean paying less. At lower profit levels, the added cost of running an S Corp can outweigh the difference.
That’s because a default LLC pays self-employment tax on nearly all of its profit, while an S Corp applies payroll tax to your salary. For a profitable LLC, that higher tax bill is the most relevant, and potentially most expensive, disadvantage of default tax treatment. That’s especially true if you plan to stay self-employed.
What is a reasonable S Corp salary?
A reasonable S Corp salary is what the IRS would consider fair pay for the services you perform for your business. As an employee-owner, you get to decide what to pay yourself. But because salary is subject to payroll tax and remaining profit isn’t, the IRS requires you to pay yourself “reasonable compensation.”
The IRS doesn’t clearly define what is “reasonable.” A helpful question to ask: what would another company pay you to do what you do for your business? Factors that shape the answer include:
- Your duties and hours worked
- Your training and experience
- What comparable businesses pay for similar services
- How much of the business’s profits are directly attributable to your efforts versus things like employees, property sales, and passive income
Do S Corp owners have to take a salary?
Yes, in almost all cases, employee-owners have to take a reasonable salary, run through a formal payroll process, in an amount that’s aligned with their work for the business.
How do I know if my LLC is an S Corp?
Your LLC is an S Corp for tax purposes if you (or your provider) filed Form 2553 with the IRS. The IRS confirms the election with an acceptance letter, known as a CP261 notice. From then on, the business files its own S Corp tax return (Form 1120-S) each year.
If you never filed the election and your LLC has one owner, it defaults to a disregarded entity. You report your LLC’s business activity on your personal tax return (on Schedule C). The IRS sees you and your business as the same taxable unit.
What is the S Corp tax rate?
An S Corp generally doesn’t pay federal income tax at the business level. Unlike a C corporation that pays its own corporate-level income tax, an S Corp is a pass-through business. The income passes through to the owners, who pay tax at their individual income tax rates.
Each state assesses its own filing, fee, or tax rate on S Corp income, and calculation methods vary. Your state’s approach is worth factoring into your decision.
Can you revoke an S Corp election if you elect too soon?
Yes, you can revoke an S Corp election, but it isn’t a quick undo. So it’s worth making the initial election with caution. To revoke, you file a revocation statement with the IRS. If you file by the 15th day of the tax year’s third month, the revocation can apply to that year. After that, it generally takes effect the following year, unless you choose a later date.
The bigger consideration is the five-year rule. Once you revoke, you generally can’t elect S Corp status again for five tax years without IRS consent. So if you revoke early and your profit grows, the rule could keep you from re-electing for a while.
That restriction also carries over to any successor business. You generally can’t sidestep it by moving your work into a new entity and electing there.
For an LLC, revoking also doesn’t return the business to its default tax treatment. Once you revoke the S Corp election, the LLC defaults to C corporation status, which comes with its own tax rules. To return to SMLLC (disregarded entity) status, you’d need to request that change with the IRS as an additional step. That’s why it’s worth waiting until you’re confident you’ll be self-employed long term and the savings opportunity is there before you elect.
How to change LLC to S Corp
You don’t convert your LLC into a different entity. You keep the LLC and elect to have it taxed as an S Corp by filing Form 2553 with the IRS. Here’s the process at a high level:
- Start with an eligible entity. For most solopreneurs, that’s an LLC. The process varies by state, but it generally involves choosing a business name, filing Articles of Organization, naming a registered agent, and drafting an operating agreement. Expect some associated fees along the way, including a state filing fee. A corporation can also elect S Corp status.
- Confirm eligibility. The business has to meet IRS requirements, such as having no more than 100 shareholders.
- File Form 2553 on time. The election is due no more than 2 months and 15 days after the start of the tax year you want it to take effect.
- Watch for IRS acceptance. The IRS confirms the election with a CP261 notice. The IRS doesn’t guarantee a specific turnaround time, so it’s worth checking current processing times before assuming it’ll be quick.
- Set up payroll and bookkeeping. Put a reasonable salary and a payroll schedule in place before you start taking distributions.
If you’ve missed the deadline, late election relief may be available. See our guide to retroactive S Corp elections. For the full walkthrough, read our step-by-step guide on how to convert an LLC to an S Corp.
After the IRS approves the election, you keep the liability protection that came with forming the LLC. You also add the potential tax benefits of S Corp status on top of it.
TL;DR: Should you convert from an LLC to an S Corp?
Think of the LLC as your legal upgrade, giving you liability protection, and the S Corp election as your tax upgrade, giving you a chance to lower your payroll taxes. Every situation is different, and the IRS doesn’t set an income threshold for eligibility. When you’re weighing potential savings, consider four things. Look at your profit relative to a reasonable salary and whether you’re committed to self-employment long term. Then factor in your tolerance for the added payroll and filing admin, and how your state treats S Corp status.
If those line up, the election could meaningfully reduce what you owe. If they don’t yet, staying an SMLLC while you build profit is often the right call, not a missed opportunity.
