Stamp Duty Land Tax when you buy property.
You pay Stamp Duty Land Tax on property like houses, flats, other buildings and land. If the purchase price is £125,000 or less you don't pay any Stamp Duty Land Tax at all. If it's more than £125,000, you pay between one and four per cent of the whole purchase price, on a sliding scale.
