A pension from abroad paid to a UK resident is UK taxable income, whatever the paying country did with it first. The treaty decides who taxes it; your tax return has to show it either way.
This is the mirror image of the situation most of this section covers, and it catches two groups: people who worked abroad and have come home, and people who moved to the UK carrying pension rights built elsewhere. In both cases the starting rule is the same. A UK resident is taxable on worldwide income, and a foreign pension is income.
The complication is that a great many foreign pensions were taxed, exempted or partially exempted under the rules of the country that paid them, and people reasonably assume that settled the matter. It did not.
The Order of Operations
- Establish your UK residence status for the year. If you are non-resident, a foreign pension is generally outside UK tax entirely — the question only arises once you are resident here.
- Identify the type of pension. State pensions, occupational pensions, personal arrangements and government service pensions are treated differently under most treaties.
- Read the relevant treaty article. Many give the taxing right over private pensions to the country of residence, and reserve government service pensions to the paying country.
- Report it on your return, in sterling, on the foreign pages.
- Claim credit for foreign tax properly paid under the treaty where the other country also has a taxing right.
Exempt abroad does not mean exempt here. If the paying country chose not to tax the pension, there is no foreign tax to credit and the UK charge falls on the full amount. People arriving from jurisdictions with generous pension exemptions are consistently surprised by this.
Currency and Timing
Foreign pensions are reported in sterling, converted on a basis HMRC accepts. Where payments are monthly, that is twelve conversions or an accepted average rate, and the choice of basis should be consistent year to year. The other timing problem is that most countries run a calendar tax year while the UK runs 6 April to 5 April, so a UK return covers parts of two foreign years. Our guide to foreign income as a UK resident covers the conversion rules in more detail.
Lump Sums Are the Sharp Edge
| Payment type | Typical UK treatment |
|---|---|
| Regular foreign private pension | Taxable as pension income, treaty credit where applicable |
| Foreign state pension | Usually taxable here, subject to the treaty |
| Government service pension | Often taxable only in the paying country |
| Lump sum from a foreign scheme | Complex — depends on the scheme, the treaty and when the rights were built |
Lump sums are where advice is genuinely warranted. A payment that was tax free where it arose is not automatically tax free here, and the UK treatment can depend on how much of the fund was built while you were UK resident. Anyone about to take one should read the lump sum guide and then speak to someone who can see both jurisdictions.
HMRC Almost Certainly Knows
Automatic exchange of financial account information means overseas accounts and payments are reported to HMRC by the country they sit in. An undeclared foreign pension is not a quiet omission; it is a visible mismatch between what HMRC has been told and what you filed. The correct response to discovering an omission is disclosure, which is treated very differently from being found.
If You Are Coming Back
Anyone returning to the UK with foreign pension rights should settle the position before arriving, because the year of return usually involves split-year treatment and the timing of a first payment can fall either side of the split date. Our guides to moving back to the UK and split-year cases cover the sequencing.
Frequently Asked Questions
Do I pay UK tax on a pension from another country?
If you are UK resident, generally yes, because UK residents are taxable on worldwide income. The treaty with the paying country determines whether that country also has a taxing right and how double taxation is relieved.
My foreign pension was tax free where it came from. Is it tax free here?
Usually not. An exemption in the paying country does not carry across, and it means there is no foreign tax to credit, so the full UK charge applies to the whole amount.
What about a government service pension?
Many treaties reserve government service pensions to the country that pays them, so they are often taxable only there. The wording varies by treaty, so it needs checking rather than assuming.
How do I convert the payments into sterling?
On a basis HMRC accepts, applied consistently. That can be the rate on each payment date or an accepted average for the year, but switching between methods to suit the outcome invites questions.
