Stamp Duty calculator
Calculate how much Stamp Duty Land Tax (SDLT) you’ll pay on a buy-to-let property purchase in England or Northern Ireland.
Additional property surcharge
If you already own a property, buying another (including buy-to-let) attracts an extra 5% surcharge on the entire purchase price. This calculator includes the surcharge by default.
