About calculatetax.co.uk

calculatetax.co.uk is a free, independent resource dedicated to providing accurate, up-to-date UK tax calculators for everyday people — employees, freelancers, limited company directors, landlords, and small business owners.

All of our calculators are built directly from the rates and rules published by HMRC and the UK Government. We review the tools when rates change, including after the Budget, Autumn Statement, and the start of a new tax year on 6 April. Each calculator should show the tax year, assumptions, and source basis used for its estimate.

We believe that understanding your tax position shouldn't require an expensive accountant or hours lost on HMRC's own (sometimes confusing) guidance. Our goal is to give you a clear, instant answer with a full explanation of how it was calculated.

What We Cover

We cover the full range of UK personal and business taxes — from PAYE income tax and National Insurance, through to VAT, Corporation Tax, Capital Gains Tax, Inheritance Tax, stamp duty, and pension relief. We are continually expanding our calculator library for 2025/26 and 2026/27.
