As a rule, a UK resident with foreign income or capital gains will need to fill in a Self Assessment tax return. But, some foreign income gets taxed differently.
PAYING TAX ON FOREIGN INCOME: Some situations do not require filling in a tax return.
For example, if the only foreign income is dividends less than £300 in total. That is providing there is nothing else to report to HMRC.
Note: The rules for paying tax on foreign income differ if your 'domicile' (permanent home) is abroad.
What if you do not usually send in a tax return. In this case you would need to register for Self Assessment before the 5th of October following the tax year that you got the income.
Note: Once you have registered you will receive a letter informing you of the next step.
As a rule, foreign income gets taxed in the same way as United Kingdom income. But, some special rules apply for:
Tax is due on pensions if you are resident or you were resident in any of the five (5) previous tax years. You will also pay tax on any foreign pension payments. That includes any 'unauthorised payments' such as some lump sums and early payments. Your pension provider will confirm how the payments get taxed.
In most cases, you will pay tax in the standard way on income from overseas property. But, different rules apply when renting out more than one property. In this case, you might be able to offset losses against other overseas properties.
Generally, working abroad and in the UK means you pay taxes in the usual way. But, some special taxation rules apply for those who work:
