What is Stamp Duty?

Stamp Duty Land Tax (SDLT) is a tax paid when you buy property or land over a certain price in England and Northern Ireland. The tax is calculated based on the purchase price of the property and varies depending on whether you're a first-time buyer, buying an additional property, or purchasing your main residence.

How Stamp Duty is Calculated

Stamp Duty is charged at different rates depending on the property price band. The current rates (from April 2025) are:

• Up to £125,000: 0%
• £125,001 to £250,000: 2%
• £250,001 to £925,000: 5%
• £925,001 to £1.5 million: 10%
• Over £1.5 million: 12%

First-time buyers get relief on properties up to £500,000, paying no tax on the first £300,000 and 5% on the portion between £300,001 and £500,000.

If you're buying an additional property, such as a second home, you'll have to pay an extra 5% in Stamp Duty on top of the standard rates. The rates for additional properties are:

• Up to £125,000: 5%
• £125,001 to £250,000: 7%
• £250,001 to £925,000: 10%
• £925,001 to £1.5 million: 15%
• Over £1.5 million: 17%

When do you pay Stamp Duty?

You have 14 days to file a Stamp Duty Land Tax (SDLT) return and pay any SDLT due. If you don't submit a return and pay the tax within 14 days, HMRC might charge you penalties and interest.
