IncomeTax.tools is a free, independent resource for understanding and estimating income tax across countries — built one country at a time, with 7 now live and more on the way.
Most income tax calculators online are either outdated, cluttered with ads before you can see a number, or built for a single country with no room to grow. We wanted something different: a fast, no-signup calculator that's accurate to the current tax year, clearly explains what it does and doesn't cover, and expands properly to new countries instead of bolting them on.
India, the USA, the UK, Canada, the UAE, Australia, and Singapore are live today — each with a full set of calculators and guides built around how that country's tax system actually works, not a generic formula reused everywhere. Our goal is to keep expanding country by country with the same level of care.
Every calculator states plainly what it does and doesn't account for — no calculator here claims to replace a CA or official filing.
We track official government sources for slab and rate changes and update calculators as tax years change.
Your income and deduction figures are calculated in your browser and never sent to or stored on our servers.
