Stamp Duty is a tax that is paid when you buy a property or certain legal documents. The amount of tax varies depending on the property's value and the rules of the specific country or region where the purchase takes place. It is usually calculated as a percentage of the property's price. This tax is typically paid at the time of the transaction and is often included in the overall costs of buying a home. Stamp Duty helps fund public services and infrastructure, making it an important part of the property buying process.
