About IncomeTaxCalc.co.uk

Making UK tax calculations accessible, accurate and completely free for everyone.

Our Mission

IncomeTaxCalc.co.uk was created with a single goal: to make UK tax calculations accessible and free for everyone. We believe that understanding your tax obligations should not require expensive software, professional consultations or complex spreadsheets. Whether you are an employee checking your payslip, a freelancer estimating your Self Assessment bill, or simply curious about how much tax you owe, our calculators are here to help.

Every calculator on this site is built using official HMRC rates and thresholds for the 2025/26 tax year. We cross-reference our figures against GOV.UK publications and update them promptly whenever rates change, so you can trust the results you see.

What We Offer

  • HMRC-verified rates — All calculations use the official tax bands, thresholds and allowances published by HM Revenue & Customs.
  • Regular updates — When the Chancellor announces changes in the Budget or Autumn Statement, we update our calculators as soon as new rates are confirmed.
  • No signup required — Every tool on IncomeTaxCalc.co.uk is completely free to use. There are no accounts, no paywalls and no hidden charges.
  • Privacy first — We do not store any personal financial data. All calculations happen in your browser and nothing is sent to our servers.
  • Comprehensive coverage — From income tax and National Insurance to dividends, capital gains, stamp duty and pensions, we cover the taxes that matter most to UK taxpayers.

Who We Are

IncomeTaxCalc.co.uk is run by a small team of tax and finance professionals who are passionate about financial literacy. Our team combines expertise in UK taxation, web development and data accuracy to deliver calculators that are both reliable and easy to use.

We are not a firm of accountants and we do not provide personalised tax advice. Our role is to give you the tools and information you need to understand how UK taxes work, so you can make more informed financial decisions or have better conversations with your own tax adviser.

Our Commitment to Accuracy

We take accuracy seriously. Every calculator is tested against known HMRC examples and edge cases, including the tapering of the Personal Allowance above £100,000, Scottish income tax bands, and the interaction between student loan repayments and pension contributions. If you ever spot a discrepancy, please get in touch and we will investigate immediately.

Important Notice

While we strive for accuracy, the information and calculations on this website are for general guidance only. They do not constitute financial, tax or legal advice. Tax rules can be complex and individual circumstances vary, so we always recommend consulting a qualified tax professional for advice specific to your situation.
