About UK Stamp Duty (SDLT)
Stamp Duty Land Tax (SDLT) is paid when buying property or land in England and Northern Ireland. Scotland uses LBTT and Wales uses LTT — rates differ.
Buy-to-let investors and second-home buyers pay an additional 5% surcharge on top of standard rates, applied across every band of the purchase price.
This calculator uses the current HMRC rate tables (effective from April 2025). Rates are applied progressively in bands — not as a flat percentage on the total price.
