Forming an LLC can make your business look more professional and help protect your personal assets.
But it does not magically remove taxes.
One of the biggest surprises for new LLC owners is self-employment tax.
Many first-time business owners think they only owe income tax on their profit. Then tax season arrives, and they realize they also owe Social Security and Medicare taxes because they work for themselves.
That extra tax can feel painful if you did not plan for it.
Self-employment tax is one of the most important things LLC owners need to understand because it affects how much money you should save, how you pay yourself, and whether an S-Corp election might make sense later.
In this guide, we will break down what the self-employment tax is, who LLC owners pay it to, how it is calculated, how it differs from income tax, and what you can do to avoid ugly surprises.
What Is Self-Employment Tax?
Self-employment tax is the tax self-employed people pay for Social Security and Medicare.
When you work as an employee, your employer withholds Social Security and Medicare taxes from your paycheck. Your employer also pays a matching portion.
But when you work for yourself, there is no employer handling that split.
So you generally pay both the employee and employer portions yourself.
That is why the self-employment tax rate is higher than what employees usually see withheld from their paychecks.
For 2026, the self-employment tax rate is generally 15.3%. This includes:
• 12.4% for Social Security
• 2.9% for Medicare
The Social Security portion applies only up to the annual wage base limit. For 2026, that limit is $184,500. Medicare tax has no wage base limit.
Why LLC Owners Pay Self-Employment Tax?
An LLC is a legal structure, not a special tax-free setup.
By default, most LLC owners are treated as self-employed for tax purposes if they actively work in the business.
That means the business profit may be subject to both income tax and self-employment tax.
This is especially common for:
• Single-member LLC owners
• Multi-member LLC members actively working in the business
• Freelancers with LLCs
• Consultants with LLCs
• Online business owners
• Ecommerce sellers
• Contractors
• Real estate service providers
• Agency owners
• Coaches and creators
If your LLC earns profit and you are actively involved in the business, self-employment tax may apply.
Self-Employment Tax vs. Income Tax
Self-employment tax and income tax are not the same thing.
This is where many new LLC owners get confused.
Income Tax
Income tax is based on your taxable income.
It applies to wages, business profit, investment income, and other taxable income.
Your income tax rate depends on your tax bracket, deductions, filing status, and total income.
Self-Employment Tax
Self-employment tax is specifically for Social Security and Medicare.
It applies to net earnings from self-employment.
So if your LLC earns profit, you may owe both:
• Federal income tax
• Self-employment tax
You may also owe state income tax depending on where you live and do business.
That is why LLC owners need to save more than they expect.
Who Pays Self-Employment Tax in an LLC?
Self-employment tax depends on how your LLC is taxed and whether you work in the business.
Single-Member LLC Owners
A single-member LLC is usually treated as a disregarded entity by default.
That means the LLC’s income and expenses are reported on the owner’s personal tax return.
If the LLC earns net profit, that profit is usually subject to self-employment tax.
For example, if your single-member LLC earns $80,000 in net profit, that profit may be subject to income tax and self-employment tax.
Multi-Member LLC Owners
A multi-member LLC is usually taxed as a partnership by default.
The LLC files a partnership return and gives each member a Schedule K-1.
Members who actively work in the business may owe self-employment tax on their share of business earnings.
The exact treatment can depend on member role, guaranteed payments, ownership terms, and tax rules.
This is one reason multi-member LLCs should work with a tax professional.
LLC Owners Taxed as S-Corp
If your LLC elects S-Corp taxation, the tax treatment changes.
Owners who work in the business must generally be paid a reasonable salary through payroll.
That salary is subject to Social Security and Medicare payroll taxes.
Remaining profits may be distributed as owner distributions, which may not be subject to self-employment tax in the same way.
This is one reason profitable LLCs sometimes elect S-Corp taxation.
But S-Corp status adds payroll, extra tax filings, and stricter rules.
How Self-Employment Tax Is Calculated?
Self-employment tax is calculated on your net earnings from self-employment, not your total revenue.
That means you first subtract business expenses from business income.
Simple Formula
Revenue minus business expenses equals net profit.
Self-employment tax is generally calculated on net earnings from self-employment.
The tax calculation also includes an adjustment where only 92.35% of net self-employment earnings are generally subject to self-employment tax.
That adjustment exists because self-employed people can deduct the employer-equivalent portion when calculating the tax.
Simple Example
Let’s say your LLC earned:
| Item | Amount |
|---|---|
| Revenue | $100,000 |
| Business expenses | $30,000 |
| Net profit | $70,000 |
Your self-employment tax is not based on the full $100,000 revenue.
It is based on the net profit after expenses.
Using the general 92.35% adjustment:
| Calculation | Amount |
|---|---|
| Net profit | $70,000 |
| 92.35% of net profit | $64,645 |
| Self-employment tax at 15.3% | About $9,891 |
This is a simplified example, but it shows why expense tracking matters.
The lower your legitimate net profit, the lower your self-employment tax.
What Is the 15.3% Self-Employment Tax Rate?
The 15.3% self-employment tax rate includes two parts.
Social Security Tax
The Social Security portion is 12.4%.
For 2026, this applies up to the Social Security wage base of $184,500.
Once your combined wages and self-employment earnings go above the wage base limit, the Social Security portion generally stops applying to income above that cap.
Medicare Tax
The Medicare portion is 2.9%.
Unlike Social Security tax, Medicare tax has no wage base limit.
That means Medicare tax continues to apply even if your income is above the Social Security wage base.
Higher-income taxpayers may also owe an additional Medicare tax, depending on total income and filing status.
Self-Employment Tax Example for LLC Owners
Let’s look at a few simple examples.
Example 1: LLC Profit of $40,000
| Item | Amount |
|---|---|
| LLC net profit | $40,000 |
| 92.35% adjustment | $36,940 |
| Estimated self-employment tax at 15.3% | About $5,653 |
This does not include income tax.
You may still owe federal income tax and possibly state tax.
Example 2: LLC Profit of $100,000
| Item | Amount |
|---|---|
| LLC net profit | $100,000 |
| 92.35% adjustment | $92,350 |
| Estimated self-employment tax at 15.3% | About $14,130 |
Again, this is only self-employment tax.
Income tax is separate.
Example 3: LLC Profit of $200,000
This gets more complicated because the Social Security portion has a wage base limit.
For 2026, the Social Security wage base is $184,500.
So the Social Security part does not apply to all income above the cap, but Medicare continues.
This is where tax software or a CPA becomes useful.
Do LLC Owners Pay Self-Employment Tax on Revenue or Profit?
LLC owners generally pay self-employment tax on net profit, not gross revenue.
This is important.
If your business earns $120,000 in revenue but spends $50,000 on legitimate business expenses, your net profit is $70,000.
Self-employment tax is generally based on that net profit, not the full $120,000.
That is why bookkeeping matters.
Good records help you track deductible expenses and avoid overpaying taxes.
What Business Expenses Can Reduce Self-Employment Tax?
Legitimate business expenses can reduce your net profit.
Lower net profit usually means lower self-employment tax.
Common deductible business expenses may include:
• Software subscriptions
• Advertising and marketing
• Website hosting
• Business insurance
• Office supplies
• Contractor payments
• Professional fees
• Business phone costs
• Internet costs used for business
• Equipment
• Travel for business
• Education related to business
• Payment processing fees
• Bank fees
• Home office expenses, if eligible
The expense must be ordinary and necessary for your business.
Do not make up deductions or mix personal expenses with business expenses.
Bad records can create problems if you are audited.
Do You Pay Self-Employment Tax If Your LLC Loses Money?
Usually, no.
If your LLC has no net profit, there may be no self-employment tax due.
For example:
| Item | Amount |
|---|---|
| Revenue | $40,000 |
| Expenses | $45,000 |
| Net profit | -$5,000 |
In this case, there is no profit to apply self-employment tax to.
However, losses can have other tax effects, and there are rules around deducting losses.
If your LLC loses money, speak with a tax professional to understand how it affects your return.
Do Passive LLC Owners Pay Self-Employment Tax?
Not always.
Self-employment tax often applies to people actively involved in running the business.
Passive owners may be treated differently depending on the structure, role, and income type.
For example, a passive investor in a multi-member LLC may not be treated the same as a working member who manages daily operations.
However, this area can get complicated.
If you have passive members, guaranteed payments, real estate income, investment income, or complex allocations, get tax advice.
Self-Employment Tax for Real Estate LLCs
Real estate LLCs can have different tax treatment depending on the activity.
Rental income is often treated differently from active business income.
For example, long-term rental income may not always be subject to self-employment tax in the same way as active service income.
But real estate dealers, short-term rental operators, property management businesses, and active service providers may have different treatment.
This is not a one-size-fits-all area.
Real estate LLC owners should work with a CPA who understands rental income and business activity rules.
Self-Employment Tax and S-Corp Election
One of the main reasons LLC owners consider S-Corp taxation is to reduce self-employment tax.
With default LLC taxation, net business profit may be subject to self-employment tax.
With S-Corp taxation, working owners generally pay themselves a reasonable salary through payroll. That salary is subject to Social Security and Medicare taxes.
Remaining profit may be taken as distributions, which may not be subject to self-employment tax in the same way.
Simple S-Corp Example
Let’s say your LLC earns $120,000 in profit before owner compensation.
Under default LLC taxation, much of the profit may be subject to self-employment tax.
Under S-Corp taxation, you might pay yourself a reasonable salary of $70,000 and take remaining profit as distributions.
The salary is subject to payroll taxes. The distributions may reduce your self-employment tax exposure.
But S-Corp taxation is not free money.
It comes with:
• Payroll setup
• Payroll tax filings
• Reasonable salary rules
• Extra business tax return
• Higher bookkeeping needs
• More compliance work
S-Corp taxation may make sense only when the tax savings exceed the additional costs.
When Should LLC Owners Consider S-Corp Taxation?
There is no magic income number that works for every business.
But many LLC owners start reviewing S-Corp status when the business has consistent profit beyond what they would reasonably pay themselves as salary.
For many small business owners, this review often starts when annual net profit is around $60,000 to $100,000+.
That does not mean every LLC in that range should elect S-Corp status.
It means the possible tax savings may be worth reviewing with a CPA.
S-Corp taxation may be worth considering if:
• Your LLC has steady profit
• You actively work in the business
• You can pay yourself a reasonable salary
• You can afford payroll and tax filing costs
• Your bookkeeping is clean
• Your CPA confirms the savings make sense
If your LLC profit is low or unpredictable, default taxation may be easier.
How Do LLC Owners Pay Self-Employment Tax?
LLC owners usually pay self-employment tax through their personal tax return.
But waiting until tax season can create a big bill.
That is why many LLC owners make estimated tax payments during the year.
Estimated Tax Payments
If you expect to owe tax, you may need to make quarterly estimated tax payments.
These payments can cover:
• Federal income tax
• Self-employment tax
• State income tax, if applicable
Estimated payments are generally due four times per year.
Many new LLC owners ignore this and get surprised later.
If you earn consistent profit, set aside money regularly and make estimated payments.
How Much Should LLC Owners Save for Taxes?
A common starting point is to save 25% to 35% of net profit for taxes.
Some owners may need more. Some may need less.
The right amount depends on:
• Total income
• Filing status
• State taxes
• Business profit
• Deductions
• Tax credits
• Other income
• S-Corp election
• Retirement contributions
• Health insurance deductions
If you are new, saving too much is better than saving too little.
A tax refund is easier to handle than a surprise tax bill.
Can You Deduct Half of Self-Employment Tax?
Yes, self-employed taxpayers generally can deduct the employer-equivalent portion of self-employment tax when calculating adjusted gross income.
This is often called the deduction for one-half of self-employment tax.
Important point: this deduction reduces income tax, not the self-employment tax itself.
It helps, but it does not erase the tax.
This is another reason self-employment tax can still feel high for LLC owners.
Self-Employment Tax vs Payroll Tax
Self-employment tax and payroll tax cover similar Social Security and Medicare taxes, but they apply in different situations.
Self-Employment Tax
Self-employment tax applies when you work for yourself and report self-employment income.
This is common for default-taxed LLC owners.
Payroll Tax
Payroll tax applies when wages are paid through payroll.
This is common for employees and S-Corp owner-employees.
With payroll, taxes are withheld from paychecks and employer payroll tax deposits are made.
With self-employment tax, you generally calculate and pay it through your personal tax return and estimated payments.
Do LLC Owners Pay Themselves a Salary?
Default-taxed LLC owners usually do not pay themselves a regular W-2 salary.
Instead, they may take owner draws or distributions.
A single-member LLC owner usually takes money out as an owner draw.
A multi-member LLC may distribute profits according to the operating agreement.
But those draws are not wages and do not avoid tax.
The business profit is generally taxed whether you leave the money in the business account or transfer it to yourself.
If your LLC elects S-Corp taxation, then working owners generally must pay themselves a reasonable salary through payroll.
Do Owner Draws Avoid Self-Employment Tax?
No.
This is a common misconception.
If your LLC is taxed under the default rules, self-employment tax is generally based on business profit, not how much money you withdraw.
For example, if your LLC earns $80,000 in profit and you only withdraw $40,000, you may still owe tax based on the profit, not just the withdrawal.
Leaving money in the business account does not automatically avoid self-employment tax.
Common Mistakes LLC Owners Make With Self-Employment Tax
1. Thinking LLC Means No Self-Employment Tax
An LLC does not remove self-employment tax by itself.
Your tax treatment depends on how the LLC is taxed and whether you are active in the business.
2. Saving Too Little for Taxes
Many new LLC owners spend the money before setting aside taxes.
Then tax season becomes painful.
Save regularly.
3. Confusing Revenue With Profit
You do not pay self-employment tax on gross revenue.
You generally pay it on net profit.
Track expenses properly.
4. Ignoring Estimated Taxes
If you wait until April to pay everything, you may face a large tax bill and possible penalties.
Quarterly estimated payments can help.
5. Taking Owner Draws Without Understanding Taxes
Owner draws are not tax-free.
The business profit is still taxable.
6. Electing S-Corp Too Early
S-Corp status can save money, but only when the numbers justify it.
If your profit is low, payroll and tax filing costs may eat the savings.
7. Not Tracking Expenses
Poor bookkeeping can cause overpayment, missed deductions, and audit problems.
Use accounting software or work with a bookkeeper.
8. Ignoring State Taxes
Self-employment tax is federal, but state income tax may still apply.
Some states also have franchise taxes, gross receipts taxes, or business privilege taxes.
How to Reduce Self-Employment Tax Legally?
You cannot simply avoid self-employment tax, but you can manage it properly.
1. Track Legitimate Business Expenses
Accurate expense tracking lowers net profit, which can reduce self-employment tax.
2. Use Retirement Contributions
Some retirement plans for self-employed people can reduce taxable income.
This may not directly reduce self-employment tax in every case, but it can reduce income tax and improve long-term planning.
3. Consider S-Corp Taxation When Profitable
If your LLC has steady profit, S-Corp taxation may reduce self-employment tax exposure.
Only do this after running the numbers.
4. Keep Clean Books
Good bookkeeping helps you avoid overpaying taxes and makes planning easier.
5. Work With a CPA
A CPA can help estimate taxes, evaluate S-Corp status, plan deductions, and avoid mistakes.
This is especially useful once your business profit becomes consistent.
Self-Employment Tax Checklist for LLC Owners
Use this checklist to stay organized:
• Know how your LLC is taxed
• Track revenue and expenses
• Calculate net profit regularly
• Save money for taxes every month
• Make estimated tax payments if required
• Understand self-employment tax vs income tax
• Keep personal and business accounts separate
• Review S-Corp election when profit grows
• Save receipts and records
• Work with a tax professional when needed
Taxes become much easier when you manage them throughout the year instead of waiting until filing season.
Final Thoughts
Self-employment tax is one of the most important taxes LLC owners need to understand.
It covers Social Security and Medicare taxes for people who work for themselves.
For 2026, the self-employment tax rate is generally 15.3%, made up of 12.4% Social Security tax and 2.9% Medicare tax.
The Social Security portion applies up to the annual wage base limit of $184,500, while Medicare tax has no wage base cap.
If your LLC is taxed under the default rules and you actively work in the business, your net profit may be subject to self-employment tax.
That tax is separate from income tax.
The best way to avoid surprises is to track expenses, understand your profit, save regularly, make estimated payments when needed, and review S-Corp taxation once your business becomes consistently profitable.
An LLC can give your business a stronger legal foundation.
But smart tax planning is what helps you keep more of what you earn.
