1099 Tax Calculator: What You'll Owe (2026)

Clients paid you $80,000 on 1099s and you spent $12,000 doing the work — so your net profit is $68,000, and at a 22% income-tax rate you owe about $24,568 in total ($9,608 of self-employment tax plus $14,960 of income tax), or 36.1% of net profit to set aside. Enter your gross 1099 income, your business expenses, and your rate below; the calculator walks from gross to net to total owed, and hands you the set-aside percentage to use on every payment.

How the 1099 math works

Nobody withholds tax from 1099 income — the full amount lands in your account, and the tax is your job. The calculation runs in three steps. First, gross minus expenses gives net profit: only ordinary and necessary business costs come off, and only net profit is ever taxed. Second, self-employment tax of 15.3% (12.4% Social Security plus 2.9% Medicare) applies to 92.35% of that net profit, following the IRS self-employment tax rules, once net earnings reach $400 for the year. Third, income tax at the rate you enter applies to the net profit — freelance dollars stack on top of any other income, so they are taxed at your highest bracket, not an average one. The set-aside percentage is the total owed divided by net profit: the share of every 1099 payment to move into savings before you spend a dollar of it. W-2 wages consume Social Security wage-base room ($184,500 for 2026), so freelance dollars above the remaining room skip the 12.4% half.

Formula: net profit = gross 1099 income − business expenses; total owed = net profit × 0.9235 × 15.3% + net profit × income-tax rate; set-aside % = total owed ÷ net profit.

Worked example: $80,000 billed, $12,000 of expenses

The defaults describe a consultant who billed $80,000 across several 1099s and spent $12,000 on mileage, software, phone, and a home office. Net profit: $80,000 − $12,000 = $68,000. Self-employment tax: $68,000 × 0.9235 = $62,798 of taxable net earnings, then $62,798 × 15.3% = $9,608.09. Income tax at 22%: $68,000 × 22% = $14,960. Total owed: $9,608.09 + $14,960 = $24,568.09, and the set-aside percentage is $24,568.09 ÷ $68,000 = 36.1% of net profit. Notice what the $12,000 of expenses bought: every expensed dollar escaped both tax layers, saving about 36 cents each — which is why tracking expenses is a higher-return habit than hunting for a better rate assumption.

W-2 vs 1099: why the forms mean different taxes

A W-2 means an employer withheld income tax, paid half your Social Security and Medicare, and sent the rest to the IRS before you ever saw it. A 1099 means none of that happened: no withholding, no employer half, and the full tax — both halves of Social Security and Medicare plus income tax — is yours to compute and pay. That is the entire reason two people with the same $80,000 of earnings can owe wildly different amounts: the employee's bill was prepaid all year, while the 1099 earner's $24,568 arrives as quarterly estimated payments plus an April balance. If you earn both kinds of income, neither this page nor a flat percentage tells the whole story, because your W-2 wages consume Social Security wage-base room ($184,500 for 2026) and change the SE-tax line — run the mixed W-2 and 1099 calculator for that case instead.

How this page differs from the set-aside calculator

This page answers a one-time question — "I received 1099 income, what will I owe on it" — by walking from gross billings through expenses to the total bill. Our tax set-aside calculator answers the ongoing question: given a single payment in hand, what percentage do you move to savings today. Use this page once a year (or once per big contract) to learn your number, then use the set-aside calculator every time an invoice clears to enforce it. Once you know the annual total, the quarterly estimated tax calculator splits it into four payments and tracks what you have already paid. The two tools share the same arithmetic; they differ only in which end of the problem you are standing at.

1099 vs W-2: what changes

Three things change when earnings move from a W-2 to a 1099. First, the base: employee tax comes out of gross pay through withholding, while 1099 tax applies only to net profit — gross billings minus ordinary and necessary business expenses — so every deductible dollar escapes both the self-employment and the income-tax layer. Second, the payroll half: an employee pays one half of Social Security and Medicare while the employer pays the other, but a 1099 earner pays both halves through the 15.3% self-employment tax on 92.35% of net profit, with no withholding smoothing it across paychecks. Third, the package: no employer benefits or paid time off are priced into the arrangement, and the whole bill arrives as quarterly estimated payments plus an April balance. If you earn both kinds of income in one year, run the mixed W-2 and 1099 calculator, which handles the wage-base overlap this page ignores.

Three ways to lower the number

First, track every deductible expense: each ordinary and necessary dollar lowers net profit, which lowers self-employment tax and income tax at the same time — our freelance tax deductions guide lists the ten most common write-offs with the one-line rule for each. Second, fund retirement as you go: traditional retirement contributions shrink the income-tax layer (though not the self-employment layer), and the solo 401(k) calculator sizes the contribution to your profit. Third, take the above-the-line adjustment the calculator leaves out: you deduct one-half of your self-employment tax on the return, which lowers income tax even though it does not change the self-employment tax itself.

Limitations of this estimate

This is a federal-only planning figure, not a filed return. It excludes state income tax, ignores the qualified business income deduction (up to 20% of qualified business income), retirement contributions, and credits, and it assumes all of your 1099 profit sits below the Social Security wage base with no W-2 wages competing for room. If any of those apply — a second earner, a day job, a high-tax state — treat 36.1% as the floor of your set-aside, not the ceiling. Estimate only — for education, not tax advice; confirm your figures with a tax professional.

Frequently Asked Questions

How is this different from the tax set-aside calculator?

This page answers “I received 1099 income — what will I owe on it”: it starts from gross billings, subtracts your expenses to get net profit, and computes the total tax bill. The tax set-aside calculator answers the ongoing question — “what percentage of each payment should I move to savings” — and is the tool to use every time an invoice clears.

Do I calculate tax on gross 1099 income or net profit?

Net profit — gross income minus ordinary and necessary business expenses. At the defaults, $80,000 of gross billings minus $12,000 of expenses leaves $68,000 of net profit, and every tax figure is computed on that $68,000. Deductible expenses lower self-employment tax and income tax at the same time, so entering gross income without expenses overstates the bill.

I also have a W-2 job — does this calculator still work?

Partly. The income-tax line still applies, but the self-employment-tax line changes: your W-2 wages consume Social Security wage-base room ($184,500 for 2026), so only the freelance dollars that fit beneath the ceiling face the 12.4% Social Security half. Use the mixed W-2 and 1099 calculator for that case — it computes the wage-base room from your salary.

What expenses can I subtract before computing the tax?

Ordinary and necessary costs of the work: mileage or actual car costs, the business share of phone and internet, software and subscriptions, home office, professional development, business insurance, and half of business meals, among others. Our freelance tax deductions guide lists the ten most common write-offs with the one-line rule for each.

When do I pay what this calculator says I owe?

Quarterly, not in April: the IRS expects estimated payments on April 15, June 15, September 15, and January 15 once you expect to owe $1,000 or more for the year, and missing a deadline costs an interest-based penalty per quarter. Divide the annual total by four for equal installments, or annualize uneven income on Form 1040-ES — our quarterly estimated tax calculator turns the annual figure into per-quarter payments.

Do I need to pay quarterly taxes on 1099 income?

Yes, once you expect to owe $1,000 or more for the year: nothing was withheld from the 1099 payments, so divide the annual total by four and send estimated payments on April 15, June 15, September 15, and January 15. Our quarterly estimated tax calculator turns the annual figure into per-quarter payments and tracks what you have already paid.

How do I calculate taxes on 1099 income?

Work from net profit, not gross billings: subtract ordinary and necessary business expenses first, then apply 15.3% self-employment tax to 92.35% of the net profit (once you clear $400 for the year), then add income tax at your marginal bracket. Enter your own gross, expenses, and rate in the calculator above and it runs all three steps.

How do I estimate taxes on 1099 income?

Project your full-year net profit, run the three-step math on it, then divide the annual total by four — estimated payments go out April 15, June 15, September 15, and January 15. Our quarterly estimated tax calculator splits any annual figure into per-quarter payments and tracks what you have already paid.

How do I calculate 1099 taxes owed?

Owed equals self-employment tax plus income tax, both computed on net profit. At this page's defaults ($80,000 gross, $12,000 expenses, 22% bracket): $68,000 net profit, $9,608.09 of SE tax, $14,960 of income tax, $24,568.09 total owed — a 36.1% set-aside on every payment.

What is the federal tax on 1099 income?

Federal tax on 1099 income has two layers and zero withholding: 15.3% self-employment tax (12.4% Social Security plus 2.9% Medicare) on 92.35% of net profit, plus ordinary federal income tax at your marginal bracket on the net profit. State income tax, where it applies, sits on top of both.
