UK Double Taxation Relief For Expats & Digital Nomads

Double taxation happens when the same income or gain is taxed by two different countries — typically because one country taxes you based on residence and the other taxes the same income because it arose there. This commonly affects people with foreign employment income, overseas pensions, foreign dividends, or property abroad while also being UK tax resident.

A Double Taxation Agreement (DTA) is a treaty between two countries that allocates taxing rights over specific types of income, and sets out how relief is given where both countries could otherwise tax the same amount. This is usually done either by exempting the income in one country, or by allowing a credit in one country for tax already paid in the other.

Under the credit method, both countries can tax the income, but the country where you're resident gives you a credit for the foreign tax already paid, so you're not taxed twice on the full amount. Under the exemption method, one country simply exempts the income from tax altogether, leaving only the other country to tax it. Which method applies depends on the type of income and the specific treaty in question.

Most Double Taxation Agreements include "tie-breaker" tests to determine which country you're treated as resident in for treaty purposes, looking in order at things like where your permanent home is, where your personal and economic ties are strongest, where you habitually live, and your nationality. Being treated as resident in only one country under the treaty is often the key to unlocking relief. Our UK tax residence assessments confirm your UK position first, which is the starting point for any treaty claim.

Claims for UK double taxation relief are most commonly made on the foreign pages of your Self Assessment tax return, where you report the foreign income and the foreign tax paid. Where a treaty exempts the income from UK tax, it is still normally reported on the return with the treaty relief claimed. It is worth keeping evidence of the foreign tax paid, as HMRC may ask to see it.

No, in the UK relief is not applied automatically. You normally need to claim treaty relief or foreign tax credit relief on your Self Assessment return, and relief will not be given unless you claim it. Separately, the foreign country may reduce withholding tax automatically or only on request, depending on its own procedures.

HMRC may ask for proof of the foreign tax paid, so keep documents such as foreign tax returns, tax assessments, payslips showing tax deducted, or certificates of tax withheld from the payer. The records should show the income, the tax deducted and the tax year they relate to. If the documents are not in English, it can help to have a translation ready.

Double taxation relief is generally limited to the lower of the UK tax and the foreign tax paid on the same income. Credit is only given for foreign tax that the treaty allows, so any foreign tax charged above the treaty rate generally cannot be credited and may need to be reclaimed from the foreign tax authority. Relief is also worked out source by source, so excess foreign tax on one income stream cannot normally be set against UK tax on another.

No — the relevant treaty article, and therefore the relief available, varies by income type. Many treaties give the country of residence sole taxing rights over pensions, give reduced withholding tax rates on dividends, and leave rental income taxable primarily in the country where the property is located. It's worth checking the specific article that applies to your income rather than assuming one set of rules covers everything.

Yes, relief can be available where both countries tax the same gain, using the Capital Gains Article of the relevant treaty or foreign tax credit relief. Treaties often give taxing rights over gains on property to the country where the property is located, while gains on other assets are usually taxable only in the country of residence, though the position varies by treaty. See our capital gains tax returns service for UK property disposals.

Even without a treaty in place, the UK generally allows unilateral relief, giving a credit for foreign tax paid against the equivalent UK tax due on the same income. This is usually less generous than treaty relief but still prevents the full impact of double taxation in most cases.

Withholding tax is tax deducted at source by the country where the income arises, most commonly on dividends, interest and royalties, before you receive the money. If the amount withheld is higher than the rate allowed under the treaty, you can usually reclaim the excess from the foreign tax authority. Only foreign tax up to the treaty rate can then be credited against your UK tax.

It depends on the country and income type. Some countries allow you to apply in advance — often via a specific form certified by HMRC — so tax is deducted at the reduced treaty rate from the outset. In other cases, foreign tax is deducted at the full domestic rate first, and you then need to reclaim the excess directly from the foreign tax authority, separately from any relief claimed on your UK return.

You typically cannot claim UK double taxation relief later than four years after the end of the tax year in which the income arose. Foreign tax is sometimes not finalised until well after the year end, so it is worth keeping track of the deadline.

HMRC will usually pay refunds into a UK bank account or issue a cheque. If you do not have a UK bank account, check HMRC's current options for overseas payments, as these can affect how quickly you are paid. Refunds of foreign tax withheld at source are claimed from the foreign tax authority, not HMRC.

If the income was previously exempt under the Remittance Basis (which has now been abolished), there may be tax implications when transferring funds to the UK. Otherwise, transferring money to the UK is typically not taxable, as tax depends on the underlying income or gain rather than the transfer itself. If you are UK resident and claim the FIG regime, your foreign income and gains are exempt whether or not you bring them to the UK.

The Temporary Repatriation Facility (TRF) allows people who previously used the Remittance Basis to pay a reduced flat rate of UK tax on foreign income and gains that arose before 6 April 2025, after which the funds can be brought to the UK without further UK tax on those amounts. The rate is currently 12% for the 2025/26 and 2026/27 tax years and 15% for 2027/28, which is the final year. Whether and when to use it depends on your circumstances, so it is worth taking tax planning advice before the deadline.
