Overseas Property Tax Guide | UK Landlords 2026

Do You Pay UK Tax on Overseas Property?

Yes. As a UK resident, you must declare income from all sources, including overseas property, to HMRC. You also have to pay UK tax on the net rental income.

How is Overseas Rental Income Taxed?

• Income: You declare the income in pounds sterling. Use the HMRC exchange rate for the relevant tax year.
• Expenses: You can deduct expenses that are ‘wholly and exclusively’ for the rental business (e.g., management fees, repairs, insurance, mortgage interest). See our guide: Allowable Expenses for Landlords.
• Tax: The net profit is added to your other UK income and taxed at your marginal rate. See our guide: Rental Income Tax Guide.

Mortgage Interest Relief for Overseas Property

The rules for mortgage interest relief on overseas residential property are the same as for UK residential property. You cannot deduct the interest from your rental income; instead, you get a tax credit of 20% of the finance costs. See our guide: Mortgage Interest Relief for Landlords.

Double Taxation Relief

You may be able to claim double taxation relief (DTR) to avoid paying tax twice on the same income.

• If you pay tax in the country where the property is located: You may be able to claim a credit against your UK tax liability for the tax paid abroad.
• The UK has Double Taxation Agreements with many countries: These agreements determine which country has the primary taxing rights.
• Unilateral Relief: If there is no agreement, HMRC may still allow you to claim relief.

How to Claim Double Taxation Relief

1. Check the Double Taxation Agreement: Determine the tax treatment under the agreement.
2. Calculate the Foreign Tax Credit: This is the lower of the foreign tax paid or the UK tax on the foreign income.
3. Claim on Your Tax Return: Complete the relevant sections of your Self Assessment tax return to claim the credit. See our guide: Landlord Tax Return Guide.

Reporting and Payment

• Self Assessment: You must report overseas rental income on your UK Self Assessment tax return.
• Payment: You must pay any UK tax due by the 31 January deadline.
• Late Payment Penalties: If you fail to report or pay, you may face penalties and interest. See our guide: Late Payment Penalties.

Other Considerations

1. Capital Gains Tax

When you sell an overseas property, you may have to pay UK Capital Gains Tax (CGT) on the gain. The rules are similar to UK property, and you may also be entitled to double taxation relief if you pay tax abroad. For more on CGT, see our guide: Capital Gains Tax for Landlords.

2. Inheritance Tax

If the property is outside the UK, it may still be subject to UK inheritance tax if you are UK domiciled.

3. Reporting if Property is Unlet

Even if the property is not let (e.g., it’s vacant or used as a second home), you must still declare this. There may be tax implications for second homes abroad, including potential ATED (Annual Tax on Enveloped Dwellings) if owned by a company.
