Self-Employed Taxes: Your Plain-English Guide for 2026

Being your own boss is a beautiful thing. Picking your hours, your clients, your vibe. But the first time a self-employed person files taxes, there's usually a moment of shock: "Wait, why do I owe THIS much?"

That shock has a name: self-employment tax. Let's break down what it is, how it's figured, and what you can do so April doesn't knock the wind out of you.

Who Counts as Self-Employed?

According to the IRS, you're generally self-employed if you:

• Run a business as a sole proprietor or independent contractor
• Are a member of a partnership that runs a trade or business
• Are otherwise in business for yourself, including part-time businesses and gig work

That covers a lot of folks: rideshare and delivery drivers, hair stylists who rent a booth, freelancers, content creators, real estate agents, consultants, and anybody getting a 1099-NEC instead of a W-2.

What Is Self-Employment Tax?

When you work for an employer, Social Security and Medicare taxes come out of every paycheck, and your employer quietly pays a matching share. When you work for yourself, you're both the employee and the employer, so you pay both halves.

That's self-employment (SE) tax. It's separate from income tax, and it's on top of it.

The 2026 self-employment tax rate

Higher earners may also owe an Additional Medicare Tax of 0.9% above certain income thresholds.

Do I have to pay it?

You generally must file a return and figure SE tax on Schedule SE if your net earnings from self-employment are $400 or more. Even if you earn less than $400, you may still need to file a return for other reasons.

How Self-Employment Tax Is Calculated (With an Example)

You don't pay SE tax on every dollar that comes in. You pay it on your net profit, which is income minus business expenses, and then only on 92.35% of that.

Let's say Keisha does hair and has a net profit of $50,000 on her Schedule C for 2026:

1. Net profit: $50,000
2. Multiply by 92.35%: $46,175
3. Multiply by 15.3%: about $7,065 in SE tax

Then she gets a little break back: she can deduct half of her SE tax (about $3,532) as an adjustment to income on her 1040. That lowers her income tax, though not the SE tax itself.

And remember, she'll still owe regular income tax on top of that, based on her taxable income after deductions.

(This example is simplified for illustration. Your numbers will depend on your full return.)

The Forms You'll File

• Schedule C (Form 1040): Your business income and expenses, which gives you net profit or loss
• Schedule SE (Form 1040): Figures your self-employment tax
• Form 1040: Your regular return, where everything comes together
• Form 1040-ES: For paying estimated taxes during the year
• Form 8995 or 8995-A: For the qualified business income deduction, if eligible

Lower Your Self-Employment Taxes the Legal Way

The best way to lower SE tax is to lower your net profit with every legitimate business expense you're entitled to. Here's where self-employed folks most often leave money on the table:

Track every business expense

Supplies, equipment, software, advertising, business insurance, professional fees, booth rent, and the business portion of your phone and internet. Keep receipts, digital is fine.

Log your business miles

For 2026, the IRS standard mileage rate for business is 72.5 cents per mile (January 1 to June 30) and 76 cents per mile (July 1 to December 31). If you drive for work, a mileage log can be worth thousands.

Claim the home office deduction (if you qualify)

If part of your home is used regularly and exclusively for business, you may qualify for the home office deduction.

Fund a retirement plan

SEP IRAs and solo 401(k)s let self-employed people save for retirement and reduce taxable income. (These lower income tax, not SE tax.)

Deduct health insurance premiums

If you're not eligible for an employer-subsidized health plan, you may be able to deduct health insurance premiums for yourself, your spouse, and dependents.

Check the QBI deduction

Many sole proprietors may deduct up to 20% of qualified business income. It lowers income tax, not SE tax, and limits apply.

Don't Forget Quarterly Estimated Taxes

Nobody's withholding taxes from your client payments, so the IRS expects you to pay as you go. If you expect to owe $1,000 or more when you file, you generally need to make estimated payments.

For 2026, the due dates are:

• April 15, 2026
• June 15, 2026
• September 15, 2026
• January 15, 2027 (the next one coming up)

Miss them, and you could owe an underpayment penalty, even if you pay everything in April.

GOAT rule of thumb: Open a separate savings account and move a set percentage of every payment into it the day it lands. Many self-employed people set aside somewhere around 25% to 30%, but your real number depends on your income, deductions, and state. Let's figure out yours.

What About the 1099 Changes?

Starting with payments made in 2026, businesses generally only have to send you a Form 1099-NEC if they paid you $2,000 or more (it used to be $600). Payment apps send a 1099-K only above $20,000 and 200 transactions.

Here's the catch: you still have to report all your income, whether you get a form or not. Fewer forms means good records matter more, not less.

Have a W-2 Job and a Side Hustle?

You're not alone. Lots of folks drive, cook, braid, design, or sell on the side. A few things to know:

• Your side income still goes on Schedule C, and SE tax still applies once your net earnings hit $400.
• Your W-2 wages count toward the $184,500 Social Security wage base first. If your combined earnings top that, the Social Security part of SE tax shrinks.
• Instead of making estimated payments, you can increase withholding at your day job with a new Form W-4. The IRS treats withholding as paid evenly through the year, which can help you avoid penalties.

Don't Forget Your Georgia Return

Your net self-employment income generally flows into your Georgia income tax return too. Georgia doesn't have its own separate self-employment tax, but your business profit is part of your state taxable income. Planning for both federal and state taxes is the only way to know your true set-aside number.

Frequently Asked Questions

What is the self-employment tax rate for 2026?

15.3% total: 12.4% for Social Security (on net earnings up to $184,500 in 2026) plus 2.9% for Medicare (no cap). It applies to 92.35% of your net self-employment earnings.

Do I pay self-employment tax if I also have a W-2 job?

Yes, if your net self-employment earnings are $400 or more. Your W-2 wages do count toward the Social Security wage base, which can reduce the Social Security portion of SE tax for higher earners.

Is self-employment tax the same as income tax?

No. SE tax covers Social Security and Medicare. Income tax is separate. Most self-employed people owe both.

Can I deduct half of my self-employment tax?

Yes. You can deduct the employer-equivalent half of SE tax as an adjustment to income on Form 1040. It reduces income tax, not SE tax.

What happens if I didn't make estimated payments?

You may owe an underpayment penalty plus the tax. It's not the end of the world. Start making payments now, and talk to a tax pro about catching up and avoiding it next year.
