Free UK tax calculators for the 2026/27 tax year
TaxFly helps you work out exactly what you’ll pay — and what you’ll keep — across the UK tax system. Whether you want your take-home pay after tax and National Insurance, the income tax on your salary, the VAT on a price, or the stamp duty on a property purchase, every answer is instant and based on official UK rules.
UK tax isn’t one-size-fits-all. Income tax has different bands in Scotland, and “stamp duty” is actually three separate taxes — SDLT in England & Northern Ireland, LBTT in Scotland and LTT in Wales. Our calculators apply the correct rules for your nation automatically.
