UK residents are generally taxed on their worldwide income — this is known as the 'arising basis' of taxation. If you earn income from abroad (overseas employment, foreign rental property, foreign dividends, foreign interest, or other sources), this income must be declared to HMRC and is subject to UK income tax and, where applicable, capital gains tax. The key relief available is the Double Taxation Relief (DTR), which prevents the same income being taxed twice. If the UK has a double tax treaty with the source country, the relief is typically the lower of the UK tax or the foreign tax paid. If no treaty exists, unilateral relief allows you to offset the foreign tax paid against your UK tax liability on the same income. Non-domiciled (non-dom) UK residents who have not been resident in the UK for more than seven of the past nine tax years could historically use the 'remittance basis', paying UK tax only on foreign income and gains brought into the UK. However, significant reforms from April 2025 replaced the remittance basis with a new 'foreign income and gains' (FIG) exemption for the first four years of UK residence. This calculator helps UK residents work out their UK tax liability on foreign income and the relief available against foreign taxes already paid.
UK tax on foreign income = foreign income × UK marginal rate; DTR credit = min(foreign tax paid, UK tax on same income); Net UK tax = UK tax - DTR credit
- 1Identify all foreign income: employment abroad (SA102), overseas property rent (SA105), foreign dividends and interest (SA106), overseas pensions
- 2Convert all foreign income to sterling at the appropriate exchange rate (average rate for the year or spot rate on date of receipt)
- 3Add foreign income to UK income on the Self Assessment return and calculate the total UK tax liability on all income
- 4Calculate what portion of the UK tax relates to the foreign income using HMRC's fractional formula: UK tax × (foreign income / total income)
- 5Claim Double Taxation Relief (DTR): the credit is the lower of the foreign tax paid and the UK tax on the same income
- 6Subtract the DTR credit from the total UK tax bill to arrive at the net UK tax payable
- 7If no double tax treaty exists, claim unilateral relief using the same formula
The US withholding tax of 15% (£750) is credited against the UK tax due on the same income.
A higher-rate UK taxpayer with US dividends gets a credit for US withholding tax paid. The credit is the lower of the foreign tax (£750) and the UK tax on the same income (£2,000). Net UK tax due = £1,250.
The UK-France double tax treaty allows the French tax to be credited against UK tax.
UK tax on the French rental income is £4,800. The French tax of £3,600 is credited in full (it is below the UK tax). The remaining £1,200 is due to HMRC.
Unilateral relief applies when no treaty exists. Credit still cannot exceed UK tax on same income.
Where no double tax treaty exists, HMRC grants unilateral relief. The foreign tax paid (£4,000) is credited against UK tax (£8,000) on the same income, leaving £4,000 due to HMRC.
The new Foreign Income and Gains exemption replaces the remittance basis from April 2025.
New UK residents in their first four tax years of residence can benefit from the FIG exemption on foreign income not remitted to the UK, under the post-2025 rules. Specialist advice is essential.

Offshore Trusts and Structures
{'title': 'Offshore Trusts and Structures', 'body': "UK residents who are beneficiaries of non-resident trusts may be attributed with the trust's income and gains under 'transfer of assets abroad' legislation. These rules are complex and specialist advice is essential."}. In the Uk Foreign Income Tax, this scenario requires additional caution when interpreting uk foreign income tax results. The standard formula may not fully account for all factors present in this edge case, and supplementary analysis or expert consultation may be warranted. Professional best practice involves documenting assumptions, running sensitivity analyses, and cross-referencing results with alternative methods when uk foreign income tax calculations fall into non-standard territory.

Foreign Tax Credits — Excess
{'title': 'Foreign Tax Credits — Excess', 'body': 'Where foreign tax exceeds the UK tax on the same income, the excess cannot be reclaimed but may be carried back against the previous year or carried forward for non-business income credits. Business income credits can be carried forward for up to 10 years.'}
| Scenario | Relief Available |
|---|---|
| Treaty country income (most countries) | Treaty relief — credit lower of UK or foreign tax |
| Non-treaty country income | Unilateral relief — credit foreign tax against UK tax |
| Dividends with withholding tax (e.g. US 15%) | Credit withholding tax against UK tax on dividend |
| Foreign rental income | Credit foreign tax paid against UK tax on rental profit |
| Foreign employment income | Credit foreign PAYE-equivalent against UK income tax |
| FIG exemption (new residents, first 4 years post-2025) | Foreign income/gains not brought to UK may be exempt |
Do I need to declare foreign income on a UK tax return?
Yes. UK residents must declare all foreign income on their Self Assessment return (SA106 for foreign income and gains). Even if tax has been paid in the foreign country, you must still declare it in the UK and claim the relief. This is particularly important in the context of uk foreign income tax calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk foreign income tax computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is a double tax treaty?
A double tax treaty is an agreement between two countries specifying which country has the right to tax particular types of income (and at what rate). The UK has over 130 double tax treaties. Where one exists, it typically prevents double taxation by giving a credit or exempting certain income.
What is the 'arising basis'?
The arising basis means you pay UK tax on income as soon as it arises (is earned), regardless of whether it is brought to the UK or not. This is the default for UK residents. It contrasts with the old remittance basis. This is particularly important in the context of uk foreign income tax calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk foreign income tax computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What happened to the non-dom remittance basis from April 2025?
The remittance basis for non-domiciled individuals was abolished and replaced by a new 'Foreign Income and Gains' (FIG) exemption from April 2025. New UK residents in their first 4 years of residence can elect to exempt foreign income and gains from UK tax. This is particularly important in the context of uk foreign income tax calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk foreign income tax computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What form do I use to declare foreign income?
HMRC form SA106 (Foreign supplementary pages) is used to declare foreign income and gains on the Self Assessment return. You also need SA102 for foreign employment, SA105 for foreign property, and SA101 for other foreign income. This is particularly important in the context of uk foreign income tax calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk foreign income tax computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Is foreign pension income taxable in the UK?
It depends on the treaty with the country paying the pension. Many treaties allow state pensions from one country to be taxed only in the recipient's country of residence, others give taxing rights to the source country. UK residents must declare all foreign pensions and check treaty provisions. This is particularly important in the context of uk foreign income tax calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk foreign income tax computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can I claim tax relief if the foreign tax rate is higher than the UK rate?
Yes, but only up to the amount of UK tax due. If the foreign rate exceeds the UK rate, the excess foreign tax cannot be refunded by HMRC. You may however be able to carry forward excess foreign tax credits in some circumstances. This is particularly important in the context of uk foreign income tax calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk foreign income tax computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Does working abroad for a UK company affect my UK tax status?
UK tax residency depends on the Statutory Residence Test (SRT), not simply where you work. Short business trips abroad do not affect residency. Extended periods abroad (typically 183+ days in a tax year) may make you non-resident in the UK, changing your tax obligations significantly. This is particularly important in the context of uk foreign income tax calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk foreign income tax computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Порада профі
If you have foreign income above £2,000 per year, or any foreign assets, you must register for Self Assessment. Do not rely on HMRC automatically knowing about foreign income — the consequences of non-disclosure can include penalties equal to 100-200% of the tax evaded in serious cases.
Чи знаєте ви?
The UK has over 130 double taxation treaties — one of the largest treaty networks in the world. The first UK double tax treaty was signed with the United States in 1945. These treaties not only prevent double taxation but also allocate taxing rights and provide exchange of information between HMRC and foreign tax authorities.
