If you would like to calculate the stamp duty that may be payable on your planned purchase simply input the purchase price of the property into our Stamp Duty Calculator. As of the 1st April 2016, people purchasing second homes or buy to let properties will have to pay a 3% surcharge on each stamp duty band. That means that for properties worth between £125,000 and £250,000, where the stamp duty is 2%, those buying a second home or buy-to-let property will pay 5%, and for properties worth more than £250,000 and up to £925,000, where the stamp duty is 5%, those buying second home or buy-to-let property will pay 8%.

The old structure was replaced with a progressive scale of charges levied on all transactions over £125,000. The new percentages apply to the value above each threshold up to the full purchase price, for example, in the same way that income tax operates.
