Our easy-to-use tool helps you estimate the stamp duty you’ll need to pay on your property purchase.

What is Stamp Duty?

Stamp Duty Land Tax (SDLT) is a tax paid by people purchasing properties in England and Northern Ireland. The tax applies to both freehold and leasehold properties, whether you’re buying outright or with a mortgage.

The amount of SDLT you will pay varies depending on the price of the property and whether it is your first home, your next home, or an additional property. Our calculator takes these factors into account, providing an estimate of the stamp duty you may owe.

How is Stamp Duty Calculated?

The amount of stamp duty you pay is calculated based on the property’s purchase price. The UK Government has set various tax bands for SDLT, which means the tax you pay increases incrementally with the price of the property. Here are the rates as of 2023:

Property or lease premium or transfer value	SDLT rate
Up to £250,000	Zero
The next £675,000 (the portion from £250,001 to £925,000)	5%
The next £575,000 (the portion from £925,001 to £1.5 million)	10%
The remaining amount (the portion above £1.5 million)	12%

For those buying a second home or buy-to-let property, a 3% surcharge applies on top of the standard rate.
