In the UK, Stamp Duty Land Tax (SDLT) is a tax levied on the purchase of property or land over a certain price threshold. Whether you’re buying a home, a piece of land, or a commercial property, if the transaction value exceeds a specified amount, you’ll be required to pay this tax. The rate of SDLT varies depending on factors such as the property’s value, location, and whether the buyer is a first-time homeowner or purchasing additional properties.
