Self-Employment Tax for LLCs: What You Owe & How to Pay

If you’ve formed an LLC and earned money through your business, you probably owe self-employment tax — even if you’ve never heard of it. This isn’t your regular income tax. It’s a separate tax that covers Social Security and Medicare contributions for business owners.

Here’s why this matters: The IRS considers LLC members who actively work in their business to be self-employed. That means you’re responsible for both the employee and employer portions of Social Security and Medicare taxes — a total of 15.3% on your business earnings.

Ignore this, and you’ll face penalties, interest, and potential problems with your future Social Security benefits. The IRS doesn’t mess around with self-employment tax. They want their money, and they have tools to get it.

What You Need to Know

Self-employment tax applies to your net earnings from self-employment — basically, your LLC’s profit after business expenses. For 2024, you’ll pay 15.3% on earnings up to $160,200 (the Social Security wage cap), then 2.9% on everything above that for Medicare.

Who pays self-employment tax:

• Single-member LLC owners (unless you elect S Corp taxation)
• multi-member LLC partners who actively participate in the business
• LLC managers who receive guaranteed payments

Who doesn’t pay it:

• LLCs that elected S Corporation tax treatment (they pay payroll tax instead)
• Silent partners who don’t actively work in the business
• LLC members who only receive distributions from passive investments

The key word is “active.” If you’re running the business, making decisions, or working in it day-to-day, you’re likely subject to self-employment tax.

When it’s due:
Self-employment tax gets calculated on Schedule SE and filed with your personal income tax return. If you owe $1,000 or more in total tax for the year, you’ll also need to make quarterly estimated tax payments.

What happens if you don’t pay:
The IRS will assess penalties and interest on unpaid self-employment tax. They can also garnish wages, levy bank accounts, or place liens on your property. Plus, not paying into Social Security means lower benefits when you retire.

How to Handle It — Step by Step

Step 1: Calculate your net earnings
Add up your LLC’s total income, then subtract all legitimate business expenses. This is your net profit — the number you’ll use to calculate self-employment tax.

Step 2: Complete Schedule SE
This IRS form calculates your self-employment tax. You’ll need your net earnings from Step 1. The form walks through the calculation, including the deduction for half of your self-employment tax (more on that below).

Step 3: File with your tax return
Schedule SE gets filed with your personal Form 1040. The self-employment tax amount transfers to your main tax return and gets added to your income tax.

Step 4: Make quarterly payments
If your total tax liability (income tax plus self-employment tax) will be $1,000 or more, make quarterly estimated payments. Due dates are January 15, April 15, June 15, and September 15.

Step 5: Keep detailed records
Save all business income and expense records. You’ll need profit and loss statements, bank statements, and receipts. The IRS can audit self-employment tax calculations, so documentation matters.

What information you’ll need:

• Your LLC’s total income for the year
• All business expense receipts and records
• Previous year’s tax return (for estimated payment calculations)
• Your Social Security number

The process typically takes a few hours if you have organized records, or several days if you need to compile everything first.

What It Costs

The tax itself:

• 15.3% on net earnings up to $160,200 (2024 limit)
• 2.9% on earnings above that threshold
• Additional 0.9% Medicare tax on earnings over $200,000

Late payment penalties:

• 0.5% per month on unpaid tax (up to 25% total)
• Interest on unpaid amounts (rates change quarterly)
• Failure to file penalty: 5% per month (up to 25% total)

Professional help costs:

• Tax preparation: $300-$800 for business returns
• CPA consultation: $150-$400 per hour
• Tax resolution services: $2,000-$5,000 for serious problems

One important benefit: You can deduct half of your self-employment tax as a business expense, which reduces your income tax burden somewhat.

How BusinessFormations.com Helps

We handle the business formation side — getting your LLC properly set up and maintaining good standing with your state. Our compliance tools send reminders for annual reports, Registered agent renewals, and other state requirements that keep your LLC valid.

For tax obligations like self-employment tax, we provide educational resources and connect you with qualified tax professionals. We don’t prepare taxes ourselves, but we make sure your business structure supports your tax planning goals.

Our compliance monitoring is worth considering if you operate in multiple states or struggle to track deadlines. Missing state compliance requirements can invalidate your LLC protection, which makes tax planning pointless.

State-by-State Differences

Self-employment tax is federal — the rules are the same regardless of where your LLC is formed. However, states have their own variations:

State income taxes:
Most states that impose income tax will also tax your LLC earnings at the state level. You’ll file your federal return first, then use those numbers for your state return.

State-specific LLC taxes:

• California charges an $800 annual fee plus gross receipts fees
• Texas has a franchise tax on LLCs with revenues over $1.18 million
• New York requires LLCs to pay a filing fee and publication costs

Multi-state complications:
If your LLC operates in multiple states, you might owe tax in each state where you do business. This gets complex quickly — definitely consult a tax professional.

Business-friendly states:
Nevada, Wyoming, and Delaware have no state income tax on LLCs, but you’ll still owe federal self-employment tax on your earnings.

Common Mistakes and How to Avoid Them

Mistake 1: Not making quarterly payments
Many LLC owners wait until April to pay all their taxes. If you owe more than $1,000, the IRS expects quarterly payments. Set aside 25-30% of your profit each quarter and make estimated payments.

Mistake 2: Mixing personal and business expenses
Using your business account for personal expenses makes it harder to calculate net earnings accurately. Keep separate accounts and only deduct legitimate business expenses.

Mistake 3: Forgetting the home office deduction
If you use part of your home exclusively for business, you can deduct home office expenses. This reduces your net earnings and lowers your self-employment tax.

Mistake 4: Not planning for the tax burden
Self-employment tax plus income tax can equal 35-40% of your profits. Many new business owners spend all their earnings and can’t pay taxes when they’re due. Always set money aside.

Mistake 5: Assuming S Corp election is always better
LLC owners often hear that electing S Corporation tax treatment saves self-employment tax. Sometimes it does, but S Corps require payroll, have more paperwork, and the savings don’t always materialize for smaller businesses.

Mistake 6: Filing as a partnership when you shouldn’t
Single-member LLCs are “disregarded entities” for tax purposes — you file Schedule C with your personal return. Some people mistakenly file partnership returns, which creates unnecessary complications.

FAQ

Do I owe self-employment tax if my LLC lost money?
No. Self-employment tax only applies to net earnings. If your LLC had a loss, you don’t owe self-employment tax, and you can potentially deduct the loss against other income.

Can I reduce self-employment tax by taking distributions instead of salary?
This doesn’t work for LLCs. Unlike S Corporation owners, LLC members can’t avoid self-employment tax by calling income “distributions.” If you actively work in the business, your share of profits is subject to self-employment tax.

What if I have a full-time job and run an LLC on the side?
You’ll still owe self-employment tax on your LLC earnings. However, if your day job already maxed out your Social Security contributions, you’ll only pay the Medicare portion (2.9%) on your LLC profits.

Do I need to make quarterly payments in my first year?
Maybe. The IRS requires quarterly payments if you’ll owe $1,000 or more in total tax. For your first year, you might qualify for the “safe harbor” rule — if you pay 100% of last year’s tax liability through quarterly payments, you won’t face penalties.

Can I deduct health insurance premiums?
Yes, if you’re self-employed and not eligible for coverage through a spouse’s plan, you can deduct health insurance premiums for yourself and your family. This reduces your income tax but not your self-employment tax.

What happens if I elect S Corporation taxation?
You’ll stop paying self-employment tax but must put yourself on payroll and pay payroll taxes instead. You’ll need to pay yourself a “reasonable salary” and can take additional profits as distributions. This can save money but increases complexity.

Conclusion

Self-employment tax is one of the biggest surprises for new LLC owners. At 15.3% of your net earnings, it can significantly impact your take-home income. The key is planning ahead — set aside money quarterly, keep good records, and understand that being your own boss means paying both sides of Social Security and Medicare taxes.

Don’t let tax complexity stop you from starting your business. Most successful entrepreneurs learn these rules as they go. The important thing is getting started with proper business formation and staying compliant with both state and federal requirements.
