Do Expats Pay Stamp Duty in the UK? The Full Breakdown

Yes, expats pay stamp duty in the UK. And in most cases, they pay more than a UK resident would for the exact same property.

That extra cost catches a lot of people off guard. Not because it is hidden, but because most brokers and advisors don't flag it early enough in the process. By the time a client finds out, they have already made an offer.

This post explains exactly how stamp duty works for expats, what the current rates are, and how the different surcharges can stack up depending on your situation.

What Is Stamp Duty and Who Pays It

Stamp Duty Land Tax, known as SDLT, is a tax on property purchases in England and Northern Ireland. It applies to residential and commercial purchases above certain thresholds and is paid at completion.

Scotland and Wales have their own equivalent taxes, LBTT and LTT respectively, with different rates and thresholds. This post focuses on England and Northern Ireland, where most expat purchases take place.

As of 1 April 2025, the standard nil-rate threshold for residential purchases sits at £125,000. You pay nothing on the first £125,000 and progressively higher rates on the amounts above that.

The Non-Resident Surcharge Explained

Non-UK residents are required to pay an extra 2 percent in stamp duty when they purchase a property in England or Northern Ireland.

This surcharge was introduced in April 2021 and applies regardless of your nationality. It is based on your physical presence in the UK, not your passport. British expats who have spent fewer than 183 days in the UK in the relevant 12-month period are treated as non-resident and must pay the surcharge.

The residency test looks at the 12 months before your purchase date. To count as UK-resident for SDLT, you need to be physically present in the UK for at least 183 days in the twelve months before completion of the sale, or in the twelve months after completion.

There is also a refund option worth knowing about. If you spend at least 183 days in the UK during the 12 months starting from the day after the effective date of the transaction, you can apply for a refund of the 2% surcharge. The claim must be made within 2 years of the date the 12-month qualifying period ends.

How the Surcharges Stack Up

This is where it gets important.

Expats buying in the UK often face more than one surcharge at the same time, and they add up quickly.

The standard 2 percent non-resident surcharge applies to most expat purchases. If the property is an additional dwelling, meaning you already own property anywhere in the world, a further 5 percent additional dwelling surcharge applies on top. The surcharges stack. A non-UK resident buying an additional residential property pays the standard rate plus 5 percent additional dwelling plus 2 percent non-resident. That is a combined surcharge of 7 percent on top of the standard rates.

A non-UK resident purchasing a £500,000 property would pay £15,000 in base SDLT plus £10,000 in non-resident surcharge, totalling £25,000. If this is also an additional property, the combined surcharges would be 7 percent.

It is also worth noting that if a non-resident buys a property with a UK resident, the surcharge applies to the whole purchase, not just to the portion attributable to the non-resident individual.

Can Expats Claim First-Time Buyer Relief

Yes, in some cases.

First-time buyer relief is available if you have never owned a residential property anywhere in the world, and you are purchasing a property in England or Northern Ireland for £500,000 or less, with a nil-rate threshold of £300,000.

The key phrase is anywhere in the world. If you own or have previously owned property in your country of residence, you will not qualify for first-time buyer relief, even if you have never owned property in the UK.

The non-resident surcharge still applies on top, even if first-time buyer relief is granted on the standard rates.

What This Means in Practice

Most expats buying in the UK fall into one of these scenarios.

First time buying anywhere, non-resident. You benefit from first-time buyer relief on the standard rates but still pay the 2 percent non-resident surcharge on top.

Already own property abroad, non-resident. You pay the standard rates plus the 5 percent additional dwelling surcharge plus the 2 percent non-resident surcharge. That is 7 percent in combined surcharges on top of the standard rates.

Planning to move back to the UK after purchase. You may be eligible for a refund of the 2 percent non-resident surcharge once you have spent 183 days in the UK within the qualifying period after completion.

Each situation is different. The numbers can vary significantly depending on the purchase price, your residency status, and whether the property counts as an additional dwelling.

Why This Matters Before You Make an Offer

Stamp duty is due at completion. By the time most expats find out how much they owe, they have already agreed a price and instructed a solicitor.

Understanding your stamp duty liability before you make an offer means you can budget accurately, factor the cost into your overall purchase calculation, and avoid any last-minute surprises that could affect your ability to complete.

A specialist expat mortgage broker will flag this early. It is one of the reasons working with someone who understands expat purchases in full makes a real difference to how smoothly the process goes.

Stamp duty for expats in the UK is manageable once you understand how the surcharges work and how they apply to your specific situation. The key is knowing before you start, not after you have committed.
