This guide is fully updated for the 2026/27 UK tax year. All Stamp Duty Land Tax (SDLT) calculations and property tax rules have been audited against official HMRC guidelines.
To regulate demand and support UK resident buyers, the UK government applies a Stamp Duty Land Tax (SDLT) surcharge on non-UK residents. This surcharge adds an additional tax burden to overseas individuals, foreign companies, and international trusts purchasing residential property in England and Northern Ireland. In this comprehensive guide, we explain the mechanics of the non-UK resident surcharge, outline the residency tests used by HMRC, and describe how to claim a refund if you move to the UK.
The Non-UK Resident Surcharge Rates
The non-UK resident surcharge is a **2%** tax premium added to standard residential rates. If an overseas buyer purchases an additional property (like a buy-to-let investment), they must pay both the 2% non-resident surcharge and the 5% additional property surcharge, resulting in a **7% tax premium**. The progressive rates for non-residents are:
| Property Value Band | Standard Non-Resident Rate (Standard + 2%) | Non-Resident + Additional Property (Standard + 7%) |
|---|---|---|
| Up to £250,000 | 2% | 7% |
| £250,001 to £925,000 | 7% | 12% |
| £925,001 to £1,500,000 | 12% | 17% |
| Over £1,500,000 | 14% | 19% |

The HMRC 183-Day Residency Test
HMRC uses a specific test for SDLT purposes that differs from the Statutory Residence Test (SRT) used for income tax. Under the SDLT residency test:
- Individual Buyers: You are treated as a UK resident for the transaction if you have been present in the UK for at least **183 days** during any continuous 365-day period starting 12 months before the purchase date and ending 12 months after.
- Foreign Companies: A company is treated as non-resident if it is incorporated outside the UK, or if it is a UK company controlled by non-UK residents (under close company rules).
Claiming Surcharge Refunds
If you pay the 2% surcharge because you have not met the 183-day presence test by the purchase date, you can claim a full refund if you subsequently meet the residency test.
Specifically, you must spend at least **183 days in the UK** during the 365 days following the transaction. Once you meet this condition, you have **2 years** from the purchase date to submit your refund claim to HMRC.
