An estimate, not tax advice. Stamp duty gets complicated fast: trusts, shared ownership, mixed-use property, inherited shares, linked purchases and permanent separation all change the answer. Confirm your figure with your conveyancer before you exchange, and check HMRC's own calculator. Rates: standard, first-time buyer and higher-rate bands from 1 April 2025; the 5% additional-property surcharge since 31 October 2024; the 2% non-resident surcharge since 1 April 2021. Source: GOV.UK, checked July 2026. Returns and payment are due within 14 days of completion.
