How the 2% Non-Resident SDLT Surcharge Works

Since 1 April 2021, buyers who are not UK residents must pay an extra 2% SDLT surcharge when purchasing residential property in England or Northern Ireland. This surcharge is applied on top of all existing stamp duty bands.

If you are an overseas investor buying a second home or buy-to-let property, you pay both the 2% non-resident surcharge and the 5% additional property surcharge — a combined 7% on top of standard residential rates.

Frequently Asked Questions

Who counts as a non-UK resident for SDLT?

An individual is treated as non-UK resident if they have not been physically present in the UK for at least 183 days during any continuous 365-day period in the 12 months before the purchase. Unlike general UK tax residency rules, this specific SDLT test looks solely at day counts.

Can I claim a refund of the 2% non-resident surcharge?

Yes. If you move to the UK and spend at least 183 days in the UK during any continuous 365-day period within 2 years after your completion date, you can claim a 100% refund of the 2% surcharge from HMRC. The claim must be made within 3 months of meeting the 183-day condition.
