Use the purchase or transfer price of your property as the basis for calculating stamp duty on property in the UK.
Calculate the stamp duty payable by multiplying your property value by the SDLT rate set by HMRC (see Resources). The rates as at 2010 are: Zero between £0 and £125,000, 1 percent between £125,001 and £250,000; 3 percent between £250,001 and £500,000. Above £500,000 the rate is 4 percent. For example, if your property or transfer value is £200,000, multiply this figure by 1 percent to give stamp duty tax of £2,000.
Recheck your calculation to ensure you have obtained the correct figure.
