Frequently asked questions

What is the self-employment tax rate?
15.3% — 12.4% for Social Security (up to the annual wage base) plus 2.9% for Medicare. It's the self-employed version of FICA: you pay both the employee and employer halves. It applies to 92.35% of your net earnings.
How much should I set aside for 1099 taxes?
A common rule of thumb is 25–30% of net income, but it depends on your bracket and state. This calculator estimates your total tax and divides it into four quarterly payments.
Can I deduct half of my self-employment tax?
Yes. Half of your SE tax is deducted from income before federal and state income tax is calculated — this tool already applies that deduction.
Does this include the QBI deduction?
No. The 20% Qualified Business Income deduction, business credits, and retirement contributions can lower your tax further. This is a baseline estimate — consult a tax professional for your full situation.

How this is calculated

Estimates use 2026 tax rules and run entirely in your browser — nothing you type is sent to a server. We compute federal income tax, Social Security, Medicare, and your state's income tax from your gross pay and pre-tax deductions.

Data sources & what's included
  • Federal income tax & standard deduction: IRS Revenue Procedure 2025-32 (2026 tax-year rate schedules, all filing statuses).
  • Social Security & Medicare: SSA 2026 wage base ($184,500) and IRS Topic 751, including the 0.9% Additional Medicare Tax.
  • State income tax: 2026brackets and standard deductions for all 50 states and DC, from the Tax Foundation's 2026 dataset cross-checked against state Departments of Revenue.

Pre-tax deductions: 401(k) reduces income-tax wages but not Social Security/Medicare wages; HSA, FSA, and health premiums reduce both.

Not included: local/city/county income taxes, personal-exemption credits, itemized deductions, tax credits, and deduction phase-outs. Your actual withholding and tax return may differ.
