What is stamp duty? Stamp Duty Land Tax (SDLT) is the tax you pay HMRC when you buy property or land over a certain price in England and Northern Ireland. How much depends on the price, whether it's your only home or an additional one, whether you're buying personally or through a limited company, and whether you're a UK resident, which is exactly what this stamp duty calculator works out for you below.
