Stamp Duty FAQ
What is Stamp Duty Land Tax (SDLT)?
SDLT is a tax you might have to pay if you buy a residential property or piece of land in England or Northern Ireland. The amount you pay is based on the property price and your status as a buyer. This calculator is based on the 2024/2025 rates.
How does the "First-Time Buyer" relief work?
First-time buyers receive a discount. They pay 0% SDLT on the first £425,000 of the property price and 5% on the portion from £425,001 to £625,000. If the property price is over £625,000, this relief does not apply, and standard rates are used.
What is the "Additional Property" surcharge?
If you are buying an additional residential property (such as a buy-to-let or a second home), you will usually have to pay a 3% surcharge on top of the standard SDLT rates for each band. This applies to properties costing £40,000 or more.
