Global Income Tax Calculator

Does a higher tax bracket mean my whole income is taxed at that rate?

No — this is the most common tax misunderstanding. Every country here uses progressive brackets, where only the portion of income inside each band is taxed at that band's rate. If you're in the US and earn $60,000 as a single filer, you don't pay 22% on all $60,000 — you pay 10% on the first slice, 12% on the next, and 22% only on the portion above about $48,475. That's why your effective (average) rate is always lower than your marginal (top) rate.

What's the difference between the Old and New tax regime in India?

The New Regime (default since FY 2023-24) has lower slab rates and a bigger effective tax-free zone — thanks to the Section 87A rebate, income up to ₹12.75 lakh for salaried employees is effectively tax-free — but it removes most deductions like 80C, HRA, and home loan interest. The Old Regime keeps those deductions but taxes income above ₹5 lakh more steeply. If you have large 80C/HRA/home-loan claims, run both regimes and compare; otherwise the New Regime usually wins for most salaried taxpayers.

Why does UK tax have a '60% trap' between £100,000 and £125,140?

Your Personal Allowance (the first £12,570 taxed at 0%) shrinks by £1 for every £2 you earn above £100,000, and disappears entirely at £125,140. So in that band you're paying 40% higher-rate tax on the income itself, plus losing tax-free allowance that then gets taxed too — the combined effect is an effective marginal rate of about 60%, even though the headline higher rate is 40%.

Why does this calculator only show Ontario for Canada?

Canada charges federal tax everywhere, plus a separate provincial tax that varies a lot — Alberta's top combined rate is around 48%, while Newfoundland's tops out over 54%. Ontario is used here as a representative, well-documented example. Your real total will differ if you live in another province or territory.

What is the Medicare Levy in Australia, and is it the same as income tax?

No — the Medicare Levy is a separate 2% charge on your taxable income that funds Australia's public health system, added on top of ordinary income tax. It phases in gradually for low incomes (below about $28,011 for singles in 2025-26) and applies in full above that. High earners without private hospital cover may also owe an additional Medicare Levy Surcharge, which this calculator does not include.

Does this calculator include US state income tax?

No — this shows federal tax only, plus FICA payroll taxes (Social Security and Medicare). US state income tax ranges from 0% (Texas, Florida, and seven other states) to over 13% (California), so your real take-home pay depends heavily on where you live and work.

What are FICA taxes and why are they shown separately from income tax?

FICA (Federal Insurance Contributions Act) covers Social Security (6.2% up to the annual wage base, $176,100 for 2025) and Medicare (1.45%, uncapped, plus an extra 0.9% above $200,000 for single filers). These fund specific federal programs and are calculated on gross wages, not taxable income after deductions — which is why they're shown as a separate line from your bracket-based income tax.

What's the difference between effective rate and marginal rate?

Your marginal rate is the rate on your last dollar earned — the top bracket you reach. Your effective rate is your total tax divided by your total gross income, blending every bracket you passed through. A high earner might have a 37% marginal rate but only a 24% effective rate, because the lower brackets on their first dollars were taxed much less.

Is this calculator accurate enough to file my taxes?

No — treat it as a planning estimate, not a filing tool. It uses published national statutory rates for the current tax year but excludes many real-world factors: state/provincial/local taxes, itemized deductions, tax credits beyond the ones modeled, self-employment tax, capital gains, and country-specific surcharges on very high incomes. Always confirm with a licensed tax professional or your country's official tax authority before filing.

How often do these tax brackets change?

Most countries adjust brackets and allowances at least once a year, often for inflation (the US and Australia) or in a national budget announcement (India's Union Budget, the UK's Autumn Budget). We update the figures on this page when new rates are officially confirmed — the tax year each country's numbers apply to is noted above the calculator.

Why is my take-home pay lower than gross income minus just the 'Total Tax' number?

It shouldn't be — Take-Home Pay here is defined as Gross Income minus Total Tax (which already includes income tax plus every additional levy shown, like FICA, National Insurance, or the Medicare Levy). If you're comparing to your actual payslip, remember real paychecks may also subtract retirement contributions, health insurance premiums, or other benefits this calculator doesn't model.
