An estimate, not tax advice
This doesn’t include the 20 % qualified business income (QBI) deduction, state or local income tax, other credits or deductions, or any tax you already paid through withholding or estimated payments. The quarterly figure is the yearly total divided by four. Your due dates depend on your situation, so check the IRS page below.How it’s calculated
- Base
- Net profit × 92.35 %
- Social Security
- 12.4 % of the base, up to $184,500 minus your W-2 wages
- Medicare
- 2.9 % of the base, no limit
- Additional Medicare
- 0.9 % of the base above $200,000 (single or head of household), $250,000 (married filing jointly), or $125,000 (married filing separately), counting your W-2 wages first
- Income tax effect
- Federal income tax with the profit minus federal income tax without it, using the standard deduction and 2026 brackets

Frequently asked questions
Do 1099 contractors pay self-employment tax?
Yes. A 1099 form reports what a client paid you. Your net profit, the amount left after business expenses, is subject to self-employment tax, and no employer withholds it for you.
Is 1099 income the same as net profit?
No. The 1099 amount is gross: everything the client paid. Net profit subtracts ordinary business costs such as software, supplies, and mileage, and only net profit is taxed as self-employment income.
What a 1099 means for your tax bill
A 1099-NEC shows the money a client paid you as a contractor. No tax is withheld from it, so you cover Social Security and Medicare yourself through self-employment tax. Your business expenses lower the base, which is why the calculator asks for net profit.
Example at $60,000 of net profit
The base is $55,410 (92.35 % of $60,000). Self-employment tax is $8,477.73, and half of it, $4,238.87, reduces your taxable income. The extra federal income tax on the profit comes to $4,511.34, so the total is $12,989.07 a year, or $3,247.27 a quarter.
Before you rely on the number
The estimate does not include the 20 % qualified business income deduction, state income tax, or any tax already paid through withholding. Treat it as a planning figure and check it against your return.
