Foreign Pension Tax in the UK 2026/27 — Reporting & Relief

Receiving a pension from another country does not, by itself, make the payment outside the UK tax system. If you are UK resident, an overseas pension is normally part of your worldwide income and may need to be reported to HMRC. The amount can include a regular pension, an annuity, a foreign social-security pension or a payment from an overseas employer scheme. The UK result depends on the legal character of the payment, your residence status, when the pension rights arose and the double taxation agreement with the country that pays it.

This is a different question from transferring a UK pension to a QROPS. A transfer is a movement of pension rights before or during retirement; this guide is about receiving money and deciding how it is taxed and reported. It also complements the general Foreign Income Reporting guide, which covers dividends, interest, employment and rental income across several categories.

Is a foreign pension taxable in the UK?

HMRC describes foreign pensions as pensions, annuities and certain lump sums paid by or on behalf of a person outside the UK. Its guidance states that tax is due on foreign pension income paid to a UK resident, although the charge and the amount can depend on the particular statutory provision and treaty. A registered pension scheme can be taxable under the pension-income rules even when it is established outside the UK; other foreign pensions can have residence-sensitive rules. That is why “the money was paid into a foreign account” is not a sufficient answer.

Start with four facts:

Do not confuse the country of the bank account with the country of source. A Canadian pension paid to a euro account remains a payment from the Canadian scheme. Conversely, moving a pension payment from an overseas account to a UK account does not create a second item of pension income. Record the original payment once, in its original currency and sterling equivalent.

Regular pension, annuity and social-security payments

A recurring overseas retirement payment is usually analysed as pension income, not as a bank deposit or capital receipt. Obtain the annual statement showing gross payments, tax withheld, payment dates, payer and the scheme or benefit description. If the provider reports only the net amount, ask it for the gross figure and withholding certificate; reporting the amount that arrived in your account can understate both the UK income and the foreign tax claim.

An annuity needs the same discipline. Do not assume that every payment from an insurance company is interest or a return of capital. The contract may determine whether it is a purchased annuity, employment-related pension or another form of income. A social-security pension may sit under a different treaty article from a private occupational pension. HMRC’s international guidance says the usual treaty approach for pensions paid in consideration of past employment is residence-country taxation, but some agreements allow source-country taxation. Social-security and old-age pensions can fall under different treaty provisions. Only the specific agreement can settle the result.

The UK tax calculation is not normally replaced by the foreign country’s tax calculation. Convert the gross income to sterling using a consistent, supportable method, include it with the applicable UK income, then consider treaty relief or foreign tax credit. Keep the source-currency schedule so that a later exchange-rate movement is not mistaken for a new pension payment.

How to report it on Self Assessment

If you need to file Self Assessment, foreign pension income is generally considered on the SA106 Foreign pages. Use the current HMRC form and notes for the relevant return year, and follow the return prompts if the payment is covered by a special exemption or treaty claim. Keep each pension or country separate rather than combining every overseas receipt into one unexplained total.

Your working paper should contain:

• the payer’s name, country and scheme description;
• gross payments by date and original currency;
• the sterling exchange rate and method used;
• foreign tax withheld, paid or refunded;
• the treaty article or HMRC rule considered;
• the SA106 box or claim used; and
• statements supporting both the income and the tax deduction.

If you were UK resident for only part of 2026/27, prepare a residence timeline and check whether the payment arose before or after the relevant change. Split-year treatment, temporary non-residence and the new foreign income and gains regime can change the analysis. A person who has left or returned to the UK should not copy the treatment from a previous year without checking the residence facts again.

The normal online deadline for a 2026/27 return is 31 January 2028, but do not wait until the deadline to request missing pension certificates. If you have not filed before and the facts require Self Assessment, HMRC’s registration deadline can also apply. The filing requirement is separate from whether the eventual tax bill is reduced by a treaty or credit.

Double taxation agreements: exemption, allocation or credit

There are three broad outcomes when the source country also taxes the pension:

1. The treaty gives taxing rights mainly to the UK. The foreign withholding may need to be reclaimed from the source country or prevented using that country’s procedure; it is not automatically a UK credit merely because it was deducted.
2. The treaty gives taxing rights mainly to the source country. The income may be treaty-exempt from UK tax, but the exact reporting and claim steps still depend on the agreement and the return instructions.
3. Both countries can tax, with relief. You may claim a foreign tax credit against the UK tax attributable to the same pension income, subject to the treaty and HMRC’s limits.

HMRC’s foreign tax credit guidance generally limits relief to the lower of the qualifying foreign tax and the UK tax attributable to that income. It is not a refund of foreign tax above the UK liability. If the source country withheld too much under its treaty rate, the excess may have to be reclaimed from that country. A credit also cannot normally be detached from the income that created it and used against unrelated UK tax.

Simple illustration

Suppose Sam receives a gross overseas pension of £12,000 after converting the original currency consistently. The source country withholds £1,800. In a simplified example, assume the UK tax attributable to that pension is £2,100 and the treaty permits a credit. The maximum UK credit would be £1,800, leaving £300 of UK tax on that income before the rest of Sam’s return is considered. If the UK tax attributable to the pension were only £1,400, the UK credit would be capped at £1,400; the remaining £400 would not become a UK repayment through the SA106 claim.

This example is not a forecast. Personal Allowance, marginal bands, other income, pension deductions, treaty limits, foreign tax timing and the statutory classification can all change the calculation.

The four-year FIG regime and overseas pensions

From 6 April 2025, eligible new UK residents can claim the four-year foreign income and gains regime (FIG regime). It replaced the old remittance basis for new years. A qualifying individual generally needs to have been non-UK resident for the previous 10 tax years, and the claim must be made rather than assumed. The regime can cover eligible foreign income, but it does not turn every overseas payment into an exempt receipt and it does not remove the need to examine the return instructions.

If you are considering a FIG claim for a foreign pension, check the current HS266 guidance and record the residence history, payment source and amount claimed. Compare the claim with the ordinary arising basis, including the effect on allowances and other reliefs. Do not apply a historical “non-dom” explanation automatically to 2026/27. A pension received under a treaty allocation can also need separate analysis from a pension merely described as foreign.

Lump sums and unusual payments

An overseas lump sum is not automatically tax-free. Ask what it represents: a pension commencement payment, flexible drawdown, an employer-financed retirement benefit, a commutation of pension rights, a refund of contributions or a payment after death. The timing of contributions, UK tax relief, residence and the scheme’s legal status can matter. HMRC’s published material distinguishes different overseas arrangements, and some payments that look similar in a bank statement are taxed under different provisions.

Before filing, request the scheme rules or benefit statement and write a short classification note. A lump sum from an overseas employer-financed scheme can have a different UK result from an ordinary periodic pension. A payment connected to a UK pension transfer can also bring transfer or temporary non-residence rules into play. If the provider cannot explain the payment, do not label it “capital” simply because it was paid once.

A safe workflow for 2026/27

Common mistakes

• Reporting the net bank credit: start with gross pension income and show foreign tax separately.
• Using a generic treaty summary: the article for private pensions may differ from the article for government or social-security pensions.
• Claiming every withholding as a UK credit: treaty limits and the UK tax attributable to the same income cap relief.
• Treating a lump sum as capital without evidence: ask the scheme what benefit was paid and why.
• Reusing last year’s residence answer: returning to or leaving the UK can change the result.
• Confusing a transfer with income: a QROPS transfer and a later pension payment are separate events.
