If you receive savings and investment income from abroad, you'll usually need to declare this on a Self Assessment tax return. You may have to pay UK Income Tax, but if you've paid foreign tax on the income you may be able to offset (deduct) this.
Income counts as 'overseas income' if it comes from outside England, Scotland, Wales and Northern Ireland. So income from the Channel Islands and the Isle of Man counts as overseas income too.
Overseas savings and investment income includes:
If you find that you're being asked to pay tax both in the country of origin and in the UK, you may be able to claim relief from double taxation by completing the foreign pages section of the Self Assessment return. The UK has signed many double taxation agreements with other countries. These are arrangements that aim to prevent double taxation.
You'll get relief on the lower of:
So if the foreign tax you're due to pay is more than that payable as UK tax, you'll still only get relief on the amount of UK tax payable.
Even if there is no double taxation agreement between the UK and the other country, relief may still be given for the foreign tax payable (called 'unilateral relief'). Your Tax Office will help you if you need further advice.
Double taxation agreements usually set out a rate of tax (called 'withholding tax') that a country can charge on a UK resident receiving certain types of income from that country (for example, dividends from companies or interest on savings).
Any claim that you make for relief against UK tax must be restricted to this minimum tax payable under the relevant double taxation agreement. You can find a list of these rates in the notes to the foreign pages of the Self Assessment return.
If you've paid foreign withholding tax at a higher rate than is listed for that type of income, you'll need to approach the overseas tax authority for a refund of the tax paid above the agreed rate.
If rental income from an overseas property is liable to UK tax, you can deduct certain expenses and allowances in the same way as you can from income from UK property.
You can claim relief for tax paid in the other country in the foreign pages section of the Self Assessment tax return.
You must report your overseas income on the foreign pages of your Self Assessment tax return.
It’s possible that you may not have to pay tax on your overseas income. This will depend on whether you’re classed as ‘resident’ in the UK for tax purposes in a tax year. The amount of income on which you pay tax may also be affected by whether you are treated as having an ‘ordinary resident’ status in the UK and your country of ‘domicile’.
You can read more about how your residence, ordinary residence and domicile can affect the UK taxation of income from your overseas investments and savings interest on the HM Revenue & Customs (HMRC) website.
