What tax year is this?

This uses 2025 IRS federal brackets (Rev. Proc. 2024-40) and 2025 state income tax rates from the Tax Foundation — the numbers you'll owe on returns filed in 2026.

Which states are covered?

All 50 states plus DC. Nine have no state income tax on wages: Alaska, Florida, Nevada, New Hampshire (taxes dividends/interest only), South Dakota, Tennessee, Texas, Washington (wages exempt; capital gains tax exists), and Wyoming. The rest are flat-rate or progressive.

Do I enter taxable income or gross income?

Enter taxable income — your gross income minus deductions (standard or itemized) and adjustments. Federal brackets apply to taxable income. This calculator uses the same figure for state purposes as a simplification; actual state taxable income can differ because state standard deductions and addbacks vary.

How is FICA calculated?

Social Security: 6.2% on wages up to the 2025 wage base of $176,100. Medicare: 1.45% on all wages. Additional Medicare: 0.9% on wages above $200,000 (single/HoH), $250,000 (MFJ), or $125,000 (MFS). Self-employment is not modeled — self-employed owe double (15.3%).

What's the difference between marginal and effective rate?

Marginal rate is the bracket your last dollar falls in (e.g., 24% federal + 9.3% California = 33.3% combined). Effective rate is total tax divided by taxable income — always lower than marginal because earlier dollars are taxed at lower brackets.

AMT, tax credits (EITC, CTC, etc.), local income taxes (e.g., NYC 3.876%, Philadelphia 3.75%), self-employment tax, non-wage FICA exclusions, and state-specific addbacks or tax credits. Treat this as an estimate, not a filing-grade calculation.
