Trusted Across the United Kingdom
Accurate, free and private financial tools built with official HMRC data.
HMRC-Sourced Data for 2025/26
Every tax calculator on UK Calculator is built using official data published by HM Revenue and Customs. When the government updates Income Tax bands, National Insurance thresholds, or capital gains allowances, we update our calculators within days. For the current 2025/26 tax year (running from 6 April 2025 to 5 April 2026), all rates, thresholds and allowances reflect the latest HMRC guidance. This means the figures you see in our tax calculator, salary calculator and National Insurance calculator match exactly what HMRC uses to assess your liability. We cross-reference multiple official sources including GOV.UK publications, HMRC technical notes and the Finance Act to ensure nothing is missed. Whether you are calculating your annual Income Tax bill, working out employer National Insurance contributions, or estimating your self-employed tax liability, you can rely on the numbers being correct and current.
Free Forever, No Registration Required
Unlike many financial tools online, UK Calculator is completely free to use. There is no premium tier, no paywall, and no signup form. You do not need to create an account, hand over an email address, or provide any personal information before using our calculators. Every single one of our 190+ calculators is available instantly, with full functionality, to anyone who visits the site. We believe essential financial tools should be accessible to everyone in the United Kingdom, regardless of income or technical ability. From a first-time employee calculating their take-home pay to a property investor working out stamp duty on a buy-to-let purchase, every user gets the same professional-grade experience without cost or restriction.
Your Privacy Is Our Priority
All calculations on UK Calculator run entirely within your web browser. When you enter your salary, mortgage amount, or any other figure, that data never leaves your device. We do not transmit your financial details to any server, we do not store them in any database, and we certainly do not share them with third parties. This client-side processing approach means your sensitive financial information remains completely private. In an era of frequent data breaches and growing concerns about digital privacy, we have deliberately chosen to build our tools so that privacy is guaranteed by design, not merely promised by policy. You can use our tax calculator with your real salary figures knowing that the data exists only on your screen and nowhere else.

Many accountants and financial advisers also use our tools for quick estimates and client illustrations.
