1099 Tax Calculator: How to Estimate Taxes on 1099 Income in 2026
Short answer: on 1099 income you owe two taxes — self-employment tax (15.3% of 92.35% of your net profit) plus federal income tax on your taxable income. A safe rule of thumb is to set aside 25–30% of your net 1099 profit for federal taxes, more if your state has its own income tax. The exact figure depends on your deductions, bracket and filing status — here's the full math so the bill never surprises you.
Use the free Freelance Rate Calculator → to build that tax into the rate you charge, so the money is already there when the 1099s arrive. Then read on to see exactly how 1099 taxes are calculated.
What a 1099 actually means for your taxes
A 1099-NEC (nonemployee compensation) is what a client sends when they pay you $600 or more as an independent contractor. Unlike a W-2, no tax was withheld — you received the full amount, and the IRS received a copy too. That's the catch: the money feels like all yours, but a chunk of it belongs to the tax system, and it's on you to set it aside and pay it.
Because nothing was withheld, the IRS expects you to pay as you go through quarterly estimated taxes rather than in one lump at filing. Skip them and you can owe an underpayment penalty even if you pay in full by April.
The two taxes on every 1099 dollar
A 1099 tax calculator is really doing two calculations and adding them up:
- Self-employment (SE) tax — 15.3%. This funds Social Security (12.4%) and Medicare (2.9%) and is applied to 92.35% of your net profit. It's separate from income tax and kicks in once net earnings reach $400. See the full breakdown in the self-employment tax calculator guide.
- Federal income tax. Your net profit (minus half of your SE tax and any deductions like the standard deduction) is taxed at the regular brackets — 10%, 12%, 22%, and up.
The key word is net: both taxes apply to profit after business expenses, not your gross 1099 total. Every legitimate deduction lowers both bills at once.

A worked example: taxes on $60,000 of 1099 income
Say you earned $60,000 on 1099s and had $8,000 of business expenses, leaving $52,000 of net profit. As a single filer taking the standard deduction:
| Step | Calculation | Amount |
|---|---|---|
| Gross 1099 income | — | $60,000 |
| − Business expenses | — | $8,000 |
| Net profit (Schedule C) | — | $52,000 |
| SE tax | $52,000 × 0.9235 × 15.3% | ≈ $7,346 |
| ½ SE tax deduction | $7,346 ÷ 2 | $3,673 |
| Taxable income (after std. deduction) | $52,000 − $3,673 − ~$15,000 | ≈ $33,327 |
| Federal income tax (est.) | 10% & 12% brackets | ≈ $3,800 |
| Total federal tax | SE + income | ≈ $11,150 |
That's about 21% of net profit in this example — and that's before any state income tax. Bump your set-aside to 25–30% and you'll have a comfortable cushion instead of a shortfall. Brackets, the standard deduction and the SE wage base change yearly, so treat these as estimates and confirm current figures at irs.gov.

How much should I set aside from each 1099 payment?
The discipline that keeps freelancers out of trouble is simple: every time a client pays you, move a fixed share of the profit into a separate tax account before you spend a cent. Here's a rough guide by income level (single filer, federal only):
| Net 1099 profit | Suggested set-aside |
|---|---|
| Under $40,000 | ~20–25% |
| $40,000–$90,000 | ~25–30% |
| $90,000+ | ~30–35% |
Add roughly your state's income-tax rate on top if you have one. Freelancers who set aside per payment almost never scramble at deadlines; those who wait to "see how the year goes" are the ones hit with a big bill and a penalty at the same time. A clean freelancer invoice template makes tracking what you've been paid effortless.
When to pay: the quarterly estimated tax dates
The IRS expects 1099 taxes in four installments covering both your SE tax and income tax:
- April 15 — Q1 (Jan–Mar)
- June 15 — Q2 (Apr–May)
- September 15 — Q3 (Jun–Aug)
- January 15 (next year) — Q4 (Sep–Dec)
You can pay online through IRS Direct Pay or EFTPS. A common safe-harbor: pay either 90% of this year's tax or 100% of last year's (110% if your income is high), and you avoid the underpayment penalty regardless of how the year shakes out.
1099 vs W-2: why your tax feels higher
As a W-2 employee, your employer withholds your income tax and pays half of your Social Security and Medicare (the other 7.65% is taken from your check, mostly invisibly). On 1099 income you're both employer and employee, so you pay the full 15.3% yourself and handle the withholding. It's not that 1099 work is taxed unfairly — it's that the costs your old employer hid are now yours to manage. The upside: business deductions and retirement options that W-2 employees never get.

Frequently asked questions
How much tax do I pay on 1099 income?
You pay self-employment tax (15.3% of 92.35% of your net profit) plus federal income tax on your taxable income, and state income tax if your state has one. For most freelancers that totals roughly 20–30% of net profit at the federal level, which is why a 25–30% set-aside is a safe rule of thumb.
How do I calculate taxes on 1099 income?
Start with gross 1099 income, subtract business expenses to get net profit, then calculate SE tax (net profit times 0.9235 times 15.3%) and federal income tax on your taxable income (net profit minus half your SE tax and your deductions). Add the two together. A 1099 tax calculator or the freelance tax calculator spreadsheet does this automatically.
Do I have to pay quarterly taxes on 1099 income?
Generally yes. Because no tax is withheld from 1099 payments, the IRS expects estimated taxes four times a year — around April 15, June 15, September 15 and January 15. Paying them on time avoids the underpayment penalty even if you reconcile everything in April.
Can I lower my taxes on 1099 income?
Yes — claim every legitimate business deduction (home office, software, mileage, equipment, health insurance, retirement contributions). Each deduction lowers your net profit, which lowers both your SE tax and your income tax. Higher earners may also benefit from an S-corp election, but that adds cost and complexity, so consult a CPA.
What happens if I don't set aside money for 1099 taxes?
You'll still owe the full amount at filing, plus a possible underpayment penalty for missing quarterly payments. The money doesn't disappear because nothing was withheld — it just arrives as one large bill in April. Setting aside a fixed share of every payment prevents that.
