Work out exactly what you owe HMRC
Tax in the UK comes from many directions — the money you earn, the things you buy, the assets you sell and the property you live in. Our tax calculators break each one down in plain English so you can see how a bill is built up, not just the final figure. Every tool is updated for the current UK tax year and uses the latest HMRC thresholds, rates and allowances.
Start with the Income Tax Calculator to see how your personal allowance, basic, higher and additional rate bands apply to your earnings, then add National Insurance to get your true deductions. If you run a business or sell goods, the VAT Calculator adds or removes VAT at the standard or reduced rate in a click.
Plan ahead, not just at year end
Selling shares, a second property or a business? The Capital Gains Tax Calculator estimates the tax after your annual exempt amount. Company directors and investors can model payouts with the Dividend Tax Calculator, while drivers can check the cost of a company vehicle with the Company Car Tax Calculator and Car Tax (VED) Calculator.
Households can budget for the year ahead with the Council Tax Calculator, and families planning their estate can use the Inheritance Tax Calculator. Each calculator shows a clear breakdown you can trust, with no sign-up and no stored data.
