UK property tax calculators
Stamp duty was devolved: three nations, three taxes, three sets of bands. Each calculator below runs on the published rates of the authority that actually collects it, alongside sold-price data for 880 English towns from HM Land Registry.
England & Northern Ireland · Stamp duty calculator
SDLT banded as HMRC charges it: movers, first-time buyer relief and its £500,000 cliff, and the 5% additional-property surcharge.
Scotland · LBTT calculator
Land and Buildings Transaction Tax, with the 8% Additional Dwelling Supplement charged on the whole price and first-time buyer relief capped at £600.
Wales · LTT calculator
Land Transaction Tax, with the UK's highest nil-rate band at £225,000 and the separate higher-rate table for additional properties.
Rates are as published by HMRC, Revenue Scotland and the Welsh Revenue Authority. These calculators cover residential freehold purchases; leases, non-residential and mixed-use purchases run on separate tables and are not modelled here.
