If you’re a first-time buyer and you are buying a property at or below £50,000, you don’t have to pay stamp duty. If you’re not a first-time buyer, you won’t be exempt from paying stamp duty. But if you are buying a concessionary purchase, the stamp duty will be calculated on the sale price of the property and not its market value. Below highlights the 2% stamp duty that would be charged on a property worth £200,000 when sold at or below market price. As you can see, buying a property at £30,000 under market value will save you £600 in stamp duty land tax. This including the discounted property price will save you £30,600. A property sold at £200,000 = £4,000 stamp duty A property sold under market value at £170,000 = £3,400 stamp duty
