    About tax calculators

    Tax in the UK is layered: income tax, National Insurance, dividend rates, capital gains allowances, and the £325,000 inheritance tax nil-rate band all interact. Self-employed earners pay Class 2 and Class 4 NI on top of income tax. Investors pay reduced CGT rates on different asset classes. Our calculators apply the current bands automatically and show working so you understand the result. See our salary calculators for PAYE-specific tools.
