🏛️ Income Tax Calculator
Income tax is progressive almost everywhere: you pay a higher rate only on the slice of income that falls inside each bracket, never on your whole income. Choose your country and filing status, enter your annual income, and this calculator applies the official 2026-27 slabs.
This is an estimate for planning only — it covers the main national/federal income tax and skips deductions, credits, state or provincial taxes, and special income types. Tax rules change yearly; the figures here are kept in one file (js/tax-rules.js) so they stay easy to refresh.

Frequently asked questions
Which countries and taxes does this cover?
It covers the national or federal income tax of six countries: USA, UK, Pakistan, India, Canada and Australia. Select your country and filing status, enter your annual income, and the calculator applies the current official slabs from its tax-rules file.
How is the tax worked out?
Almost every country uses progressive brackets: each slice of income is taxed at the rate for its bracket, so a higher bracket never taxes your whole income. Australia adds an optional 2% Medicare levy via its dedicated checkbox.

Can I use this for my actual tax return?
No. This is a planning estimate only: it skips deductions, credits, state or provincial taxes and special income types. Tax rules change yearly, so confirm the final figures with an official source or a tax professional.
