Free Tax Calculators 2026

Tax calculators

Tax is where a good calculator earns its keep, because the rules differ by country, change by year, and punish guesses. This shelf gathers the estimators for the systems our visitors actually file under: income tax for the United States, Canada, Australia and the United Kingdom, plus the consumption taxes that hide inside prices, sales tax, GST and VAT, and the property tax most buyers meet exactly once, at the worst possible moment, when they are already stretching to complete. The shelf is organised by country first and tax type second, so you always start inside the system you actually file under, not some generic world average.

Each estimator is built on the published brackets, thresholds and rates for its country, and each page states its tax year and shows its formula and a worked example, so you can check the answer yourself. Treat the answers as strong estimates for planning, comparing job offers, checking a payslip, pricing an invoice, not as a filed return; a calculator cannot see your deductions, your credits or your circumstances. Everything runs in your browser, free, and your income figures are never sent anywhere or stored. The pages are written for the questions people bring mid decision, an offer letter, a cross border move, a first invoice, where a good estimate today beats a return next spring.

The US Income Tax Calculator walks federal brackets and the standard deduction, while the Canada Income Tax Calculator, Australia Income Tax Calculator and UK Income Tax Calculator each follow their own thresholds, offsets and allowances. For prices, the US Sales Tax Calculator and Canada Sales Tax Calculator add tax on top, and the UK VAT Calculator, EU VAT Calculator and AU GST Calculator can strip it back out of a tax inclusive price. The UK Stamp Duty Calculator completes the shelf, pricing the land tax on a purchase by band. Together they move you from gross pay to net pay to the tax inside a price, without ever leaving the shelf.
