Stamp Duty Land Tax (SDLT) is a tax paid when purchasing property or land in England and Northern Ireland above a certain threshold. From April 2025, the nil-rate band returned to £125,000, making the tax applicable on more transactions.
Additional surcharges for overseas buyers
Buyers classified as non-UK residents typically pay an additional 2% surcharge on top of standard SDLT rates. If purchasing an additional or buy-to-let property, a further 3% surcharge applies — on the top slice of a high-value purchase, total rates can reach 17%.
Legal ways to reduce your SDLT
- SPV structure — purchasing through a Special Purpose Vehicle can sometimes offer SDLT advantages depending on your circumstances.
- Timing — if you can establish UK residency (183+ days) before completion, you may avoid the overseas buyer surcharge.
- Mixed-use or commercial properties are subject to non-residential SDLT rates, which can be significantly lower for high-value transactions.
