Among the tax costs of buying in the UK, Stamp Duty (SDLT, Stamp Duty Land Tax) is the single largest amount paid at one time, at Completion. For overseas buyers the confusion is usually not “whether it applies,” but “how many layers stack up”: on top of the standard bands there is an additional-property surcharge, then a non-resident surcharge, and a company purchase follows a different set of rules again. This article breaks down the England and Northern Ireland calculation layer by layer, and flags the different systems in Scotland and Wales.
Overseas Buyer SDLT Is Made Up of Three Layers
For an overseas individual buyer purchasing residential property in England or Northern Ireland, Stamp Duty is generally made up of three stacked layers: the standard residential bands + the additional-property surcharge of 5% (generally applies where the buyer holds more than one home worldwide after completion; an exemption is available where the new property replaces a main residence and the old home is sold within 36 months of completion) + the non-resident surcharge of 2%. All three can apply at the same time. The standard bands are as follows (current as of August 2026):
| Price Band | Standard Rate |
|---|---|
| Up to £125,000 | 0% |
| £125,001 – £250,000 | 2% |
| £250,001 – £925,000 | 5% |
| £925,001 – £1,500,000 | 10% |
| Above £1,500,000 | 12% |
In other words, for a non-resident buyer who already owns a home overseas, the combined rate at each price band is “standard + 5% + 2%.”
The 2% Non-Resident Surcharge: Who Counts as Non-Resident
The test is whether you spent fewer than 183 days in the UK in the 12 months before the purchase — fewer than 183 days makes it a non-resident transaction, and the 2% surcharge applies on top of all other residential rates. This test is based purely on the number of days spent, and is not the same test as nationality or visa category. Separately, an individual buyer who makes up the required number of days of residence within the specified period before or after the transaction can apply to amend the original stamp duty return to claim back this 2% surcharge.
Company Purchases: A Different Set of Rules
Companies and other non-natural persons buying residential property are subject to a special rule: buying a single residential property worth more than £500,000, where it is not for a qualifying rental business or similar use, can mean Stamp Duty is charged at a flat 17% — calculated on the whole price, not by band. A qualifying commercial letting business can be exempted, moving instead to the standard bands plus surcharges; but the exemption carries a 3-year condition period, and if a connected person moves in during that period the exemption is withdrawn and the tax is reclaimed. The overall tax difference between company and personal ownership is covered in the related article comparing ownership for four different purposes; where the purpose involves personal or family use or inheritance planning, it is worth first getting an ownership-structure assessment.

Scotland and Wales: Not SDLT
Stamp duty is a devolved matter — SDLT only applies to England and Northern Ireland. Scotland uses LBTT, with an Additional Dwelling Supplement (ADS) of 8%; Wales uses LTT, with higher residential rates banded from 5% to 17% depending on the price band. When comparing prices across regions, the tax cost must be calculated separately.
Frequently Asked Questions About Overseas Buyer Stamp Duty
Does first-time buyer relief apply to overseas buyers?
First-time buyer relief carries an owner-occupation requirement and interacts with the other surcharge rules, so an overseas buyer purchasing to let generally struggles to benefit from it; whether it applies in a specific case depends on the purpose of the purchase and the ownership structure — it is worth confirming the tax estimate with a solicitor before making an offer.
When is Stamp Duty paid, and who handles it?
It is filed and paid within the statutory deadline after completion; in practice this is handled by the buyer’s solicitor (conveyancer) at completion, with the tax prepared together with the balance of the purchase price. How this fits into the rest of the buying process is covered in the related article on the overseas buyer’s purchase process.
Is there also tax when selling?
Selling follows a different set of rules: a non-resident selling a UK home must report and pay Capital Gains Tax within 60 days of completion, even where no tax is ultimately due. Tax during the holding period is handled separately according to how the property is held (company or personal).
Stamp Duty is the earliest cost locked in when buying in the UK — working out how the three layers stack, and when the company rules are triggered, before making an offer keeps the budget on a sounder footing. Want to double-check your own situation? Leave us a message in the form below!
