How it works

1

Pick your country

Choose from 7 countries, each built around how that country's tax system actually works — regimes, brackets, federal vs. state, whatever applies.

2

Enter your numbers

Plug in your income, deductions, or relevant details into the calculator. Nothing is saved, tracked, or emailed — the calculation happens right in your browser.

3

Get an instant, itemized estimate

See exactly how the number breaks down — bracket by bracket — plus links to related guides if you want the full context before filing.

Why people use IncomeTax.tools

🌍

Built country-by-country, not templated

Each country's calculators are built around its actual tax structure — India's Old vs New Regime, the UK's National Insurance, Canada's CPP/EI, Singapore's CPF — not a generic formula reused everywhere.

🔓

No signup, no paywall

Every calculator and guide is free to use, with no account, no email capture, and no artificial limit on how many times you use it.

📅

Reviewed for the current tax year

Every page shows the tax year or Year of Assessment it reflects, along with a last-reviewed date, so you know exactly how current the figures are.

🧮

Itemized, not a black box

Results show the full breakdown — which bracket applied, what got deducted, what the effective rate works out to — instead of just a single final number.

Frequently asked questions

Is IncomeTax.tools free to use?

Yes. Every calculator, guide, and reference page on this site is completely free — no signup, no account, no paywall, and no limit on how many times you use them.

How accurate are the calculators?

Our calculators are built from publicly available tax rules and reviewed periodically, but they produce estimates for planning purposes, not final or authoritative figures. Tax law changes frequently and individual situations vary, so always confirm your final numbers with a qualified tax professional or your country's official tax authority before filing. See our full disclaimer.

Do you store or share the numbers I enter?

No. Calculations run directly in your browser — the income figures and personal details you enter into a calculator are never transmitted to or stored on our servers.

Which countries do you currently cover?

India, the USA, the UK, Canada, the UAE, Australia, and Singapore are live today, each with a full set of calculators and guides. More countries are planned — see our full sitemap for everything currently available.

Can I suggest a new calculator or report an error?

Yes, please do — accuracy matters to us. Use the contact page to flag an outdated figure, suggest a new calculator, or request a country we haven't covered yet.
