Self-employment & 1099 tax guide
The complete 2026 guide to self-employment and 1099 taxes
When you switch from a W-2 paycheck to 1099 or freelance income, the biggest shock is the tax bill. As an employee, your employer quietly pays half of your Social Security and Medicare for you. The moment you go independent, you pay both halves — that is the 15.3% self-employment tax. Understanding it is the difference between a freelance career that pays and one that drains your savings every April.
This guide breaks down exactly how self-employment tax works in 2026, how a 1099 income really compares to an equivalent W-2 salary, when you must pay quarterly, and how an LLC or S-corp election changes the picture — all using current IRS rules. To see your own numbers, use the self-employment tax calculator and the 1099 vs W-2 calculator.
How the 15.3% self-employment tax is built
| Component | Rate | Applies to |
|---|---|---|
| Social Security (OASDI) | 12.4% | Net SE earnings up to $184,500 |
| Medicare | 2.9% | All net SE earnings |
| Additional Medicare | +0.9% | Earnings above $200,000 (single) |
| Combined base SE tax | 15.3% | First $184,500 of profit |
One critical detail: you do not pay SE tax on your full profit. The IRS lets you multiply net profit by 92.35% first (because employees do not pay FICA on the employer's share either), then apply the 15.3%. You also deduct half of your SE tax as an above-the-line income-tax deduction.
1099 vs W-2: the real comparison
A common rule of thumb is that a 1099 contractor needs roughly 25–30% more headline pay than a W-2 salary to break even, because they cover the employer FICA half, buy their own benefits, and lose paid leave. But two factors narrow the gap: deductible business expenses and the 20% Qualified Business Income (QBI) deduction, which can shave a fifth off the income-tax portion of pass-through profit. Use the 1099 vs W-2 income calculator to find your true break-even rate.
Quarterly estimated taxes
There is no employer withholding on 1099 income, so the IRS expects you to prepay. If you will owe $1,000 or more, make quarterly estimated payments on Form 1040-ES, due mid-April, mid-June, mid-September and mid-January. A safe-harbor rule protects you from penalties if you pay at least 100% of last year's tax (110% if your AGI was over $150,000). Most freelancers set aside 25–30% of every invoice.
Sole proprietor vs LLC vs S-corp
A single-member LLC is taxed identically to a sole proprietor — it gives liability protection but no automatic SE-tax savings. An S-corp election can cut SE tax by paying yourself a reasonable salary (subject to FICA) and taking the rest as distributions (not subject to SE tax). The catch: payroll, filings and accountant fees usually only pay off once profit clears roughly $80,000. Below that, stay a sole proprietor or LLC and keep it simple.

Questions
Self-employment tax FAQ
How much is self-employment tax in 2026?
Self-employment tax is 15.3% of net self-employment earnings: 12.4% for Social Security on profit up to the 2026 wage base of $184,500, plus 2.9% Medicare on all profit. You calculate it on 92.35% of your net profit, and you can deduct half of the tax when figuring your income tax.
What is the difference between 1099 and W-2 for taxes?
A W-2 employee splits FICA with their employer, each paying 7.65%. A 1099 self-employed worker pays both halves as 15.3% self-employment tax, but can deduct business expenses and half of the SE tax. The effective gap is often smaller than it looks once expenses and the QBI deduction are counted.
Do I have to pay quarterly estimated taxes?
If you expect to owe $1,000 or more in tax for the year, the IRS generally requires quarterly estimated payments using Form 1040-ES, due in April, June, September and January. Missing them can trigger an underpayment penalty, so most self-employed people set aside 25 to 30 percent of each payment.
Should I form an LLC or S-corp to save on self-employment tax?
A single-member LLC is taxed the same as a sole proprietor, so it does not by itself cut self-employment tax. An S-corp election can reduce SE tax by splitting income into salary and distributions, but only makes sense once profit is high enough (often $80,000+) to justify payroll and accounting costs.
