Frequently Asked Questions
Do UK residents pay tax on overseas income?
Yes. UK residents are taxed on their worldwide income — all income, wherever earned in the world, must be declared to HMRC on a self-assessment return.
What is double tax relief?
If you pay tax in another country on the same income, you can claim double tax relief (also called a foreign tax credit) to avoid being taxed twice. Relief is limited to the lower of the UK tax or foreign tax on that income.
Which countries have double tax treaties with the UK?
The UK has over 130 double tax treaties. Major ones include the USA, Germany, France, Australia, Canada, UAE, and India. Check GOV.UK for the full list.
Do I need to declare foreign income if tax was already paid abroad?
Yes. You must declare all foreign income on your self-assessment return, even if foreign tax was deducted at source. You can then claim relief.
What if there is no double tax treaty?
You can still claim Unilateral Relief — a credit for foreign tax paid even without a treaty, under UK domestic law. The credit is still limited to UK tax on the same income.
How are foreign dividends taxed in the UK?
Foreign dividends are taxed at UK dividend rates (8.75% basic, 33.75% higher, 39.35% additional) but you can claim credit for foreign withholding tax paid.
What is a foreign tax credit?
A foreign tax credit is a reduction in UK tax equal to the foreign tax paid on the same income. It is the mechanism by which double tax relief is given.
Do I owe NI on foreign employment income?
If you are working for a UK employer overseas, or for certain other circumstances, National Insurance may still apply. The rules are complex — check with HMRC or an adviser.
What about the foreign rental property?
Rental income from overseas property is taxable in the UK as foreign income. You can deduct mortgage interest, repairs, and management fees before declaring the net profit.
Is offshore interest from foreign bank accounts taxable?
Yes. Interest from foreign bank accounts must be declared. Foreign tax withheld at source can usually be credited against UK tax.
What is the Worldwide Disclosure Facility?
HMRC's Worldwide Disclosure Facility allows those with undeclared offshore income to come forward voluntarily. Penalties are lower than if HMRC discovers the omission.
Can I use a foreign loss to offset UK income?
Foreign losses from the same category of income can often be offset against UK income, but the rules vary. Foreign rental losses can offset other foreign rental income.
