What is stamp duty?

Stamp Duty Land Tax (SDLT) is a tax that may be payable when you buy a property or land in England and Northern Ireland. The amount you pay depends on the purchase price and your circumstances (for example, whether it’s your first home or an additional property).

Please note that rates differ in Scotland and Wales, but England and Northern Ireland share the same rates. 

Please use the Land and Building Transaction Tax calculator if you are purchasing property in Scotland.

Use the calculator to estimate your SDLT

Our calculator is designed to help you budget by estimating the amount of stamp duty land tax based on the details that typically affect the amount due, including:

• Property price

• Whether you’re a first-time buyer (relief may apply up to certain limits)

• Whether it’s your main home or an additional property (additional properties usually pay a higher rate)

• Whether you’re a UK resident for SDLT purposes (a surcharge can apply in some cases.

How to use the Stamp Duty Calculator

1. Enter the purchase price of the property.

2. Select the option that matches your situation (first-time buyer, home mover, additional property, etc.).

3. View your estimated Stamp Duty amount straight away.

You can also adjust the details to compare scenarios — for example, changing the price or switching between buyer types — to help you plan your overall moving costs.

A quick note about your result

The calculator provides an estimate based on the information you enter and current published SDLT guidance.

Stamp Duty can be affected by individual circumstances (such as replacing a main residence, specific ownership situations, or reliefs), so your solicitor or conveyancer can confirm the final amount and handle the Stamp Duty Land Tax return as part of your purchase.
