England & Northern Ireland · 2026 rates
Stamp Duty Land Tax (SDLT) is charged on increasing portions of the price. The calculator uses the residential bands effective from 1 April 2025 (current for 2026): nothing up to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1.5m and 12% above. If you will own more than one residential property, a 5% additional-property surcharge is added to every band. First-time buyers pay nothing up to £300,000 and 5% on the portion to £500,000, with no relief above £500,000.
Scotland (LBTT) and Wales (LTT) operate different systems. Always confirm the figure with HMRC's calculator or your solicitor before completion.
