UK Tax Calculators

Updated for the 2026/27 tax year
Every calculator here works differently from the single-tax tools you'll find elsewhere: each figure is calculated as part of your whole tax position — reflecting how one tax actually interacts with your Personal Allowance, the High Income Child Benefit Charge, student loan and pension contributions, not just that one tax in isolation. That's the difference between a number and the real number.
Free, no sign-up, real 2026/27 HMRC and MHCLG rates. Pick a single tax below, or jump straight to the full calculator to see everything together.
