1099 Tax Calculator: How Much to Set Aside From Freelance Income
This 1099 tax calculator estimates how much of your freelance, contract, or gig income could go to tax in 2026, and what share to set aside as you get paid. It combines self-employment tax with the extra federal income tax the work adds, and can include a flat state rate.

Under these assumptions, $50,000.00 of net 1099 income could add about $10,460.89 of tax for 2026, so setting aside about 21% of it, or $2,615.22 a quarter, would cover the estimate.

The quarterly figure divides the annual estimate by four. Actual estimated-tax due dates and safe-harbor rules differ and can depend on last year's tax. Sources: IRS Rev. Proc. 2025-32 (2026 brackets and standard deduction), Topics 554, 560, and 751.
Assumptions
- Uses 2026 federal brackets and the standard deduction for the filing status; itemized deductions, credits, and dependents are not modeled.
- The qualified business income (QBI) deduction is not included, so federal income tax may be overstated for eligible businesses.
- Self-employment tax uses 92.35% of net earnings, the $184,500 Social Security wage base reduced by W-2 wages, and the $400 minimum.
- Half of the self-employment tax is deducted before figuring income tax.
- State tax is a flat rate on net 1099 income; real state and local rules vary.
- Tax already withheld from W-2 wages is not counted.

Why 1099 Income Needs Its Own Estimate
No one withholds tax from 1099 income. An employer takes out income tax, Social Security, and Medicare from each paycheck, but a client paying a contractor usually sends the full amount. The tax is still owed, so freelancers need to set money aside and often make estimated payments during the year.
Two federal taxes apply. Self-employment tax covers Social Security and Medicare, and income tax applies to the profit like any other income. The calculator estimates both.
How the Estimate Works
The calculator follows these steps for tax year 2026:
- Net Income: 1099 income minus business expenses.
- Self-Employment Tax: 15.3% of 92.35% of net income, with the Social Security part capped at the $184,500 wage base. The self-employment tax calculator walks through this step in detail.
- Income Tax Increase: Federal income tax on your W-2 wages plus net 1099 income, minus half of the self-employment tax and the standard deduction, compared with the tax on your W-2 wages alone.
- State Tax: An optional flat rate on net 1099 income.
The 2026 brackets and standard deductions come from IRS Rev. Proc. 2025-32. The standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.
A Worked Example
Take a single filer with $60,000 of 1099 income, $10,000 of expenses, and no other job. Net income is $50,000. Self-employment tax is $7,064.78, and half of it, $3,532.39, is deducted. Taxable income becomes $30,367.61, which produces $3,396.11 of federal income tax. The total is $10,460.89, about 20.9% of net income, or about $2,615.22 a quarter. These are Fin Loom calculations, and they assume no other income, credits, or deductions.
Add a W-2 job and the picture changes. The salary already uses the standard deduction and the lowest brackets, so each 1099 dollar is taxed at a higher income tax rate, and the share to set aside rises.
Set-Aside Percentage and Quarterly Payments
The dominant result is the share of net 1099 income to set aside to cover the estimate. The quarterly figure simply divides the annual total by four. Actual estimated-tax rules differ: due dates are spread unevenly, and safe-harbor rules based on last year's tax can lower what you must pay during the year. Treat the quarterly number as a budgeting guide, not a payment instruction.
What This Estimate Does Not Include
The calculator leaves out the qualified business income (QBI) deduction, which can lower income tax for many sole proprietors, so its income tax figure may be higher than what you owe. It also ignores credits, itemized deductions, dependents, tax already withheld from wages, and local taxes, and it uses one flat state rate rather than real state rules.

Frequently Asked Questions
How Much Should I Set Aside for 1099 Taxes?
It depends on your income, expenses, filing status, and other earnings. The calculator estimates a share from your own numbers, such as about 20.9% of $50,000 net income for a single filer.
Is 1099 Income Taxable if I Don't Receive a Form?
Yes. Whether or not a client sends a 1099 form, net self-employment earnings are taxable income, and self-employment tax generally applies at $400 or more.
Why Is My 1099 Tax Higher Than My Paycheck Withholding Rate?
You pay both halves of Social Security and Medicare as a self-employed person, 15.3% in total, on top of income tax. An employee pays only half through payroll.
