Calculate Your SDLT — FreeSDLT is a tax you pay when buying property or land in England and Northern Ireland above a certain threshold. The amount depends on the purchase price, whether it's your first home, an additional property, or a company purchase. Scotland and Wales have their own equivalents (LBTT and LTT) with different rates and thresholds.
Second properties attract an additional 5% surcharge on top of standard SDLT rates (increased from 3% in October 2024). On a £300,000 second property, the total SDLT would be £17,500 — significantly more than the £2,500 a first-time buyer would pay on the same property. Our calculator shows the exact difference.
First-time buyers benefit from a higher nil-rate threshold. As of April 2025, you pay no SDLT on the first £300,000 of a property priced up to £500,000. Above £500,000, standard rates apply. Our calculator automatically applies the correct relief based on your buyer type.
Our SDLT engine uses the current HMRC rate bands and is updated whenever rates change. It covers residential, commercial, and mixed-use properties, including the non-UK resident surcharge and company purchase rates. However, stamp duty rules can be complex — we always recommend confirming with your solicitor before exchange.
Yes. Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT), both with different rates and thresholds. Our calculator lets you switch between all three regions instantly.
