4. Paying tax on foreign income
You don’t need to fill in a tax return if your only foreign income is dividends under £300 in total and you don’t have anything else to report.
Different rules may apply if your permanent home (‘domicile’) is abroad.
Register for Self Assessment
If you don’t usually send a tax return, you need to register by 5 October following the tax year you had the income.
You’ll get a letter telling you what to do next after you’ve registered.
Filling in your tax return
Use the ‘foreign’ section of the tax return to record your overseas income or gains.
Include income that’s already been taxed abroad to get Foreign Tax Credit Relief, if you’re eligible.
HMRC has guidance on how to report your foreign income or gains in your tax return in ‘Foreign notes’.
