1099 Taxes Explained: What US Freelancers Owe

Your first profitable year of freelancing ends with a surprise nobody warns you about: the tax bill. A W-2 employee never thinks about payroll taxes because their employer quietly pays half of them. A freelancer is both employer and employee, so you pay both halves — and you owe the money in quarterly chunks rather than tidy paycheque deductions. This guide walks through exactly what you owe on 1099 income in 2026, with one fully worked example you can adapt to your own numbers.

Quick answer: US freelancers pay two taxes on 1099 profit: federal income tax (10%–37% on taxable income) and self-employment tax of 15.3% on 92.35% of net earnings. A single freelancer with $80,000 of net profit in 2026 owes roughly $18,800 in total — about 23.5% — which is where the common “set aside 25–30%” advice comes from.

The two taxes behind every 1099

When clients pay you $600 or more in a year, they report it to the IRS on Form 1099-NEC and send you a copy. That form is not a tax bill — it is a paper trail. You report the income on Schedule C (profit or loss from business), subtract your business expenses to get your net profit, and then two separate taxes apply to that number.

1. Federal income tax. The same progressive brackets employees face, from 10% to 37%. It applies to your taxable income — net profit minus the half-of-SE-tax deduction and minus the standard deduction ($16,100 for single filers in 2026) or your itemised deductions.

2. Self-employment tax. This is the freelancer’s version of Social Security and Medicare taxes. An employee pays 7.65% and their employer pays the other 7.65%. You are both, so you pay the full 15.3% — 12.4% for Social Security and 2.9% for Medicare. Critically, the standard deduction does not reduce this tax; it is calculated on net earnings after business expenses only.

State income tax is a third layer in most states and is completely separate — the federal numbers below do not include it.

Self-employment tax, line by line

The 15.3% rate looks simple, but four details change what you actually pay:

• The 92.35% multiplier. SE tax applies to 92.35% of your net profit, not the full amount. This is the IRS’s rough equivalent of the employer-half deduction employees get automatically.
• The $184,500 wage base (2026). The 12.4% Social Security portion stops once your net earnings pass $184,500. The 2.9% Medicare portion has no cap and continues on every dollar.
• Half of the SE tax is deductible. You deduct 50% of your SE tax as an above-the-line adjustment on Schedule 1. This lowers the income subject to federal income tax — but it does not reduce the SE tax itself.
• The $400 threshold. If your net self-employment earnings are under $400 for the year, you owe no SE tax at all (you may still owe income tax).

One more line for high earners: above $200,000 of net earnings (single) there is an additional 0.9% Medicare tax, figured separately on Form 8959. It is not part of the 15.3% and none of it is deductible.

A worked example: $80,000 of freelance profit

Take a single freelancer with $80,000 of net profit in 2026 — that is income after business expenses, before any tax. Here is the full calculation:

Step	Calculation	Result
Net profit	Given	$80,000
Earnings subject to SE tax	$80,000 × 92.35%	$73,880
Self-employment tax	$73,880 × 15.3%	$11,304
Deduction for half of SE tax	$11,304 ÷ 2	$5,652
Adjusted gross income	$80,000 − $5,652	$74,348
Taxable income	$74,348 − $16,100 standard deduction	$58,248
Federal income tax	$1,240 + ($38,000 × 12%) + ($7,848 × 22%)	$7,527
Total tax bill	$11,304 + $7,527	$18,831

That is an effective rate of about 23.5% on the $80,000 profit. Notice how the income tax part ($7,527) is smaller than many people fear — the standard deduction and the half-SE-tax deduction shield a large slice — while the SE tax ($11,304) is the bigger, unavoidable chunk.

Where does the “set aside 25%” rule actually come from?

Every freelancer forum repeats the same advice: put 25–30% of each payment into a separate account. It is not superstition — it falls straight out of the maths above. Running the same calculation at different profit levels (single filer, 2026 figures, before the 20% qualified business income deduction many freelancers can also claim) gives:

Net profit	Total tax (federal)	Effective rate
$50,000	$10,461	20.9%
$80,000	$18,831	23.5%
$100,000	$25,746	25.7%

The rate climbs with income because higher brackets take a bigger bite and the SE tax keeps compounding. The 25–30% buffer exists for three reasons the federal table does not show: state income tax (not included above), income growth during the year pushing you into a higher bracket than you planned for, and the fact that quarterly estimates are guesses — the buffer absorbs the error. Treat 25% as your floor, 30% as your comfort zone, and move the money the day each payment lands.

What about quarterly payments?

The IRS runs on pay-as-you-go: if you expect to owe $1,000 or more after withholding and credits, you must pay in four instalments during the year using Form 1040-ES. For 2026 the deadlines are 15 April, 15 June, 15 September 2026, and 15 January 2027. Miss them and April’s bill arrives with an underpayment penalty on top. There is a full walkthrough of who pays, how much per quarter, and the safe-harbour shortcut in our guide to quarterly estimated taxes.

Deductions most new freelancers miss

Every dollar of legitimate business expense shrinks your net profit before any of the maths above begins — which reduces both taxes, not just income tax. The commonly overlooked ones:

• Home office (simplified method). $5 per square foot of dedicated workspace, up to 300 square feet — a $1,500 deduction with almost no paperwork.
• Health insurance premiums. Deductible above the line if you are self-employed and not eligible for an employer’s plan.
• Retirement contributions. SEP IRA or Solo 401(k) contributions cut this year’s taxable income while building the pension nobody else is funding for you.
• The boring essentials. Software subscriptions, a share of your phone and internet bill, professional memberships, and mileage to client meetings all count.

Freelance taxes feel heavy because you see the full number at once instead of watching it drip out of a payslip. The system itself is mechanical: two taxes, one worked example, quarterly instalments, and a separate savings account that gets 25–30% of every payment the day it arrives. Do that and April becomes paperwork, not a panic.
