Calculate how much Stamp Duty Land Tax (SDLT) you will pay on a property purchase in England or Northern Ireland. Covers standard purchases, first-time buyer relief and the additional property surcharge for buy-to-let and second homes. Updated for 2024/25.
Stamp Duty Land Tax (SDLT) is paid when you buy a property or land over a certain price in England and Northern Ireland. In Scotland the equivalent tax is LBTT and in Wales it is LTT — this calculator covers England and Northern Ireland only.
First-time buyers pay no SDLT on the first £425,000 of a property purchase. On the portion between £425,001 and £625,000 the rate is 5%. If the property costs more than £625,000 the standard rates apply with no first-time buyer relief.
If you already own a property and are buying an additional one — such as a buy-to-let or holiday home — a 3% surcharge applies on top of the standard rates on the full purchase price.
