What is Stamp Duty on a Second Home in the UK?
Stamp duty on a second home: buyers in England pay a 5% stamp duty surcharge on top of standard rates. This applies to buy-to-let properties, holiday homes, and any additional property purchase.
When you buy a second property in England or Northern Ireland, you pay higher stamp duty land tax (SDLT). From October 2024, the additional property surcharge increased from 3% to 5%. This means on a £300,000 second home, you'd pay approximately £20,000 in stamp duty, compared to £5,000 for someone buying their main residence - an extra £15,000. The surcharge applies from the first pound and affects all price bands. Scotland and Wales have their own equivalent taxes with different rates.
Stamp duty rates and thresholds change periodically. Always verify current rates with HMRC or a qualified adviser. Your Home Finance Ltd is authorised and regulated by the Financial Conduct Authority (FCA 989177).
