What is Stamp Duty?
Stamp Duty Land Tax (SDLT) is a government tax that must be paid when purchasing a property in England. It applies to both new and pre-owned homes. The amount of Stamp Duty you pay depends on the purchase price of the property, as well as your buyer status—whether you're a first-time buyer, home mover, or purchasing a second home.
How is Stamp Duty calculated on new builds?
When buying a new build property, Stamp Duty fees are calculated based on the price of the home you are buying. If the price of your new home is below certain thresholds, you may be exempt from paying Stamp Duty.
