Income Tax Calculator (2026)
Estimate 2026 US federal income tax using the verified IRS brackets, plus FICA and state tax.
Inputs
How it works
Subtract pre-tax deductions and the larger of itemized/standard deduction, apply 2026 federal brackets, add a state approximation, and compute FICA (Social Security 6.2% up to $184,500 + Medicare 1.45% + 0.9% surtax over the filing-status threshold).
Frequently asked questions
Are these amounts an exact tax bill?
No. They use verified 2026 IRS/SSA figures but ignore credits, phase-outs and AMT. Use tax software or a CPA to file.
Marginal vs effective rate?
Marginal is the rate on your next dollar. Effective is total tax ÷ taxable income — always lower because earlier brackets fill first.
Standard or itemized?
Take whichever is larger. 2026 standard deduction: Single $16,100 · MFJ $32,200 · HoH $24,150 · MFS $16,100.
How is state tax handled?
Eight states impose no income tax. The rest are approximated at their top rate — see your state's brackets for a precise figure.
