Stamp duty surcharge on second homes
If you’re buying a second home or any additional residential property in England or Northern Ireland, you’ll pay a stamp duty surcharge on top of the standard rates. This guide explains how the surcharge works, how much it will cost you, and whether any exemptions might apply.

What is the stamp duty surcharge?
The stamp duty surcharge is an additional 5% added to each band of the standard stamp duty rates when you purchase an additional residential property. It applies if, at the end of the transaction, you own two or more residential properties and you have not sold your previous main home.
The surcharge was introduced at 3% in April 2016 and increased to 5% in October 2024. It applies to the entire purchase price, calculated across the standard stamp duty bands with the 5% addition at each level.
How much does it add to your costs?
The impact of the surcharge is significant. On a £300,000 second home, you would pay the standard stamp duty plus the 5% surcharge, which adds £15,000 to your tax bill. On a £500,000 property, the additional surcharge element is £25,000.
This is a substantial upfront cost that you need to factor into your purchasing budget alongside your deposit, legal fees, and moving costs. Use our stamp duty calculator to get an exact figure for the property you’re considering.
When does the surcharge apply?
The surcharge applies when you buy a residential property and already own one or more other residential properties. It applies even if the additional property is very low value, is held through a company, or is located overseas. It also applies if you’re buying a property jointly and either party already owns another residential property.
Companies, trusts, and other non-natural persons buying residential property worth £40,000 or more also pay the surcharge, in addition to potentially being subject to the 17% flat rate for corporate purchases.
Are there any exemptions?
You may be able to reclaim the surcharge if you sell your previous main home within 36 months of buying a new one. This applies to situations where you buy a new main residence before selling your old one — commonly known as being in a chain.
The surcharge does not apply to caravans, mobile homes, or houseboats. Properties worth less than £40,000 are also exempt. If you’re replacing your main residence and the purchase and sale happen at the same time, the surcharge should not apply, though the conveyancing needs to be handled carefully.
