A tax bracket calculator shows you exactly how progressive taxation breaks down for your income. Most people understand brackets in theory but mis-estimate their actual tax because they confuse marginal rates (the rate on your last dollar) with effective rates (the rate you actually pay on your whole income). This calculator shows both, plus the bracket-by-bracket breakdown.
8 jurisdictions: US Federal (single filer), California, New York, Texas, Florida, Washington, UK, and Canada federal. 2024 rates. Optional deduction input. Browser-only -your income data never leaves the page.
Most people don't know the difference. Most calculators don't help. We show both, prominently labeled.
SmartAsset and TaxAct gate features behind paid filing. We do math, no promotions, no email gate.
US, UK, Canada in one tool. Useful for remote workers and international employees.
Your income is private. Other calculators log it. We never see it.

Yes. Unlimited use, no signup. SmartAsset and TaxAct have free calculators but heavily push paid filing services; we do tax math only and stay out of your way.
US Federal (single filer), California, New York, Texas, Florida, Washington (last three have no state income tax), UK (England/Wales/NI), Canada federal. 2024 rates. Add state + federal manually for combined.
Marginal = the rate on your last dollar earned (the bracket you're in). Effective = total tax divided by gross income (the rate you actually pay on your whole income). Most people confuse them. Effective is always lower than marginal.
Brackets are progressive. The first $11,600 is taxed at 10%, the next chunk at 12%, etc. Even at $200K, only the top slice gets the highest rate. The bracket-by-bracket breakdown shows you exactly how much each layer contributes.
Single deduction input that subtracts from gross before bracketing. Use it for the standard deduction ($14,600 US single in 2024) or itemized deductions. We don't model specific credits like child tax credit or earned income credit.
Not modeled. The calculator does income-tax brackets only. Add ~7.65% for FICA (US) or ~12% for NI (UK) for a complete take-home estimate.
We update rates annually. As of the 2024 brackets shown. For 2025 figures, the IRS publishes inflation-adjusted brackets each November; we'll roll them in when published.
No. This shows tax bracket math. Real tax filing involves credits, phase-outs, AMT, capital gains, retirement contributions, state-specific deductions. Use this for planning and quick estimates, your tax software for filing.
Not yet. Current version is single-filer only. MFJ brackets are roughly double the single-filer thresholds. We'll add MFJ + Head of Household + MFS in a follow-up.
No. The calculator runs in your browser. Your income, deductions, and computed tax stay on your laptop. No upload, no log, no third-party analytics on the input.
