Tax Deductions Expats Can (and Can’t) Claim on UK Rental Mortgages

June 16, 2025

If you’re an overseas property owner in the UK, it’s crucial to learn about the relationship between rental revenue and tax. Mortgage-related tax reduction affects your returns regardless of your nationality, which means this information is relevant to both British expats and foreign investors who are currently living overseas. However, the rules around what you can and cannot deduct have recently changed.

In this article, we’ll look at common traps for expat landlords, interest relief and permitted deductions.

What Is an Expat Buy-to-Let Mortgage?

Buy to let tax UK advice

Designed for non-residents who want to rent out UK properties, an expat buy to let mortgage UK often comes with more stringent requirements and higher interest rates. Many lenders will look at revenue in overseas currencies and require a solid credit history. Although these products offer good investment opportunities, expats should think carefully about the tax laws linked to rental revenue before they go ahead.

Your property cash flow can be significantly affected by the type of mortgage you choose, so careful planning and consideration is essential. Engaging a specialist expat mortgage broker with many years of experience working with expats will certainly make the process much smoother.

Navigating Tax Deductible Interest for Expats

Some landlords were able to deduct pre-tax mortgage interest from their rental income until April 2020. Nowadays however, things are different. Expats using expat mortgage UK buy-to-let loans are no longer entitled to a full interest exemption. Instead, they can receive a mortgage interest tax credit fixed at 20%.

Additionally, higher rate taxpayers now pay more tax on rental income than they did in the past and this rule applies regardless of where the landlord lives. Expats should also be aware that mortgage interest relief only applies to residential property lettings. Commercial properties are subject to fewer restrictions.

What Expenses Are Still Allowable?

Although mortgage interest relief is now limited, many other expenses are still tax-deductible. Expats can still deduct:

  • Letting agent fees
  • Property maintenance and repairs
  • Insurance costs
  • Service charges and ground rent
  • Accountant’s fees
  • Council tax (if the landlord pays this whilst the property is vacant)

These deductions apply as long as they are totally and solely for rental use. Personal expenses, which can include renovations rather than repairs, are not deductible. For instance, you can replace a broken boiler, but if you upgrade a kitchen to a high-end model, this will be treated as an improvement. Keeping clear, organised records of all property-related expenses is essential for creating an accurate and compliant tax return.

Traps to Avoid with Mortgage Deductions

Many landlords have fallen into the trap of misinterpreting the 20% tax incentive. Some property owners based overseas incorrectly believe they are entitled to comprehensive interest relief. This error can result in underpayment of taxes and potentially tough HMRC penalties.

Average home mortgage interest rates can also cause problems as the tax incentive remains at 20% even when interest rates climb. Rising interest rates won’t reduce the amount of tax you’re liable to pay. Expats must consider this when planning investments. It’s also very important to differentiate between residential and commercial property restrictions. Generally speaking, a proactive strategy is much more preferable to making last-minute changes when tax is due.

Income Tax and Non-Resident Landlords Scheme

Expat mortgage UK tax tips

Tenants or letting agents may deduct basic rate tax from rent payments before they pass them on to landlords living abroad. To receive rental income without deductions being made, expats must register with HMRC and meet compliance requirements.

Staying compliant is essential, and failing to do so can result in withheld income and potential penalties. Even when registered under the Non-resident Landlords Scheme, expat landlords still need to submit an annual Self-Assessment tax return to HMRC.

You’re advised to speak to a tax consultant with experience in foreign matters if you own several homes or have a large rental income. Expats must register under the UK’s Non Resident Landlord Scheme (NRLS) run by HMRC to receive gross rental revenue. If you fail to register, you could face reduced income, with tax being withheld from you.

Property Ownership Structures for Expats 

Many expats consider buying UK property through a limited company. One advantage is that mortgage interest can be fully deducted as a business expense. However, corporate ownership comes with higher costs and more regulatory responsibilities. What the right choice for you is will depend on your personal tax situation, property value and investment goals.

Getting professional advice is essential before you take this route. For some investors, especially those who are building a property portfolio, the long-term tax benefits can outweigh the added complexity. Buying through a UK limited company enables you to deduct all your mortgage interest. However, the extra compliance, taxes and setup costs mean careful planning and bespoke financial guidance are crucial.

Conclusion

While expat mortgages can generate valuable property income, changing tax laws make professional advice essential. Knowing what mortgage interest is still eligible for relief – and what isn’t – can make all the difference when it comes to profits and penalties. By staying informed and compliant, expats may profit substantially from the UK property market. Accurate records and skilled assistance blended with a systematic strategy can help you maximise your investment. Check with Expat Mortgages UK today.

Do Expats Pay Stamp Duty Differently? UK Property Tax Explained

May 12, 2025

Navigating the UK property market as an overseas investor or UK expat can be complex, especially when it comes to understanding how taxes like Stamp Duty Land Tax (SDLT) work. Whether you are eyeing up a buy-to-let opportunity or making plans to move back home in the future, knowing how stamp duty works for expats can have a big impact on your funding choices and widen your pool of options.

In this guide, we’ll break down the stamp duty rules for foreigners and foreign residents, giving you information about the 2% surcharge and potential refunds while telling you how Expat Broker UK acts as an expert expat mortgage broker.

What is Stamp Duty Land Tax (SDLT)?

In England and Northern Ireland, the purchase of property automatically triggers a stamp duty tax liability for the buyer, as this tax is administered by central government / HMRC. The amount of stamp duty owed depends on the value of a property, whether it’s a residential or buy-to-let purchase and the buyer’s residency status.

Standard SDLT Rates for Residential Properties:

  • Up to £250,000: 0%
  • £250,001 to £925,000: 5%
  • £925,001 to £1.5 million: 10%
  • Over £1.5 million: 12%

An additional 3% surcharge applies to Stamp Duty Land Tax for people who purchase second homes or use real estate as an investment property. The tax amounts to 3% on top of standard SDLT rates.

The 2% Surcharge for Non-UK Residents: What Expats Need to Know

Since April 2021, a 2% Stamp Duty Land Tax (SDLT) surcharge has applied to property purchases made by non-UK residents. This additional tax aims to level the playing field for local buyers and increase funding for infrastructure and housing in the area.

Who Does the 2% Surcharge Apply To?

The 2% surcharge applies to:

  • Non-UK resident (those who haven’t spent at least 183 days inside the UK in the year before purchase)
  • Both expats and foreign nationals

This 2% surcharge is applied in addition to the standard SDLT rates and any other applicable surcharges, such as the 3% charge for second homes.

Example:

An expat buying a £500,000 buy-to-let asset might pay:

  • Standard SDLT: £15,000
  • Buy-to-let surcharge: £15,000
  • Non-resident surcharge: £10,000
  • Total SDLT: £40,000

Are There Any Exemptions for Expats?

Yes, under certain conditions, some expats can reclaim the 2% surcharge. If you go on to become a UK resident (spend 183 days in the UK) within twelve months of the transaction, you could apply for a surcharge refund.

All of this means that careful financial planning for expats is essential. It’s worth consulting an expat mortgage advisor or working with an experienced loan advisor on a regular basis to evaluate your eligibility and optimise your purchase timing.

Key Stamp Duty Considerations for Expats

1. Type of Property Matters

The tax implications differ between residential and buy-to-let houses. Buy-to-let homes incur higher SDLT due to the extra 3% surcharge.

2. Joint Purchases

If you’re buying with a UK resident associate, the surcharge may still apply if one of you is a non-resident.

3. Limited Companies and Trusts

Buying property through an enterprise or trust can trigger specific taxes. If the entity is managed from overseas, it could be considered a non-resident purchase and generate the 2% surcharge.

4. Property Ownership History

If you already own property within the UK or abroad, this might also impact your SDLT legal obligations. If your purchase is classed as a second home, you’ll pay the extra 3% regardless of your residency status.

How Expats Can Reduce Their SDLT Liability

While tax cannot be avoided completely, strategic planning may lessen your general liability:

  • Purchase timing: Consider buying after setting up UK residency.
  • Use of trusts: With the right financial advice, trusts may also deliver better tax performance.
  • First-time consumer relief: If eligible and buying a primary residence, a first-time consumers may pay less or even no SDLT.
  • Professional guidance: An expert expat mortgage dealer will help you to examine all economic implications and advise you on the most efficient mortgage strategies.

Why Partner with a Specialist Expat Mortgage Broker?

SDLT is only one part of the equation. As an expat or foreign national, navigating the UK expat mortgage lending criteria can be tough. Challenges like overseas currency earnings to a limited or non-existent UK credit score history can make traditional banks hesitant to lend the funding you require.

What If You Become a UK Resident After Purchase?

If you return to the UK and meet the 183-day rule within 12 months of your purchase, you can ask for a refund of the 2% surcharge. You can do this by submitting an amended SDLT return.

However, this is a time-sensitive procedure and the SDLT needs to be claimed within 2 years of the transaction. With a knowledgeable UK expat mortgage team on your side, you can meet all deadlines with ease.
