What is stamp duty?

When you buy property or land, you normally have to pay tax on it. This is called Stamp Duty Land Tax in England and Northern Ireland, Land and Buildings Transaction Tax in Scotland and Land Transaction Tax in Wales.

The amount of tax you’ll pay in total depends on where the property is, the purchase price, as well as whether you intend to live in it or rent it out. There may also be a discount if you are a first time buyer.

Read our Stamp Duty guide for more information.

How does the stamp duty calculator work?

1) Tell us what region you are buying in

2) Select whether you will be a first time buyer or not, and if not, whether you would then own 2 or more properties

3) Enter the property price and hit enter - then see how much stamp duty you would have to pay

How have the stamp duty rules changed?

Stamp duty relief changed on April 1st 2025, affecting the thresholds at which you pay. The value at which you need to start paying Stamp Duty decreased from the previous threshold of £425,000 to properties over £300,000. For more information about the changes, visit our stamp duty guide.
