The standard guidance on expat pension contributions — that non-residents can contribute up to £3,600 gross per year regardless of earnings — is correct as far as it goes, but it describes only one scenario. International employment creates a spectrum of situations, from the UK employee on short-term secondment (who may retain full UK earnings and full annual allowance access) to the long-term emigrant with no UK income (who is limited to the basic £3,600 floor). Between these extremes are numerous other situations that require careful analysis.
This guide addresses the specific scenarios of international employment — the rules for seconded employees, dual-contract arrangements, Relevant UK Individual status, and non-UK employer contributions — rather than repeating the general non-resident guidance covered elsewhere.
The Relevant UK Individual Framework
The pension tax relief system revolves around the concept of the Relevant UK Individual (RUI). This status determines whether a person can contribute more than the basic £3,600 gross per year.
You are a Relevant UK Individual if either of the following is true:
You have relevant UK earnings in the current tax year — earnings that are subject to UK income tax, including employment income from a UK employer (or from a non-UK employer where the income is taxable in the UK), trading profits subject to UK income tax, and certain other UK-source earned income
You were UK resident in at least one of the five preceding tax years — this catch-all provision allows returning expatriates and those who have recently left the UK to maintain their full contribution rights for up to five years after leaving
RUI status is the gateway to contributing more than £3,600. A person who is an RUI with relevant UK earnings of £80,000 can contribute up to £80,000 (subject to the £60,000 annual allowance) with tax relief at their marginal rate. A person who is not an RUI (or an RUI with no relevant UK earnings) is limited to £3,600 gross.
Scenario 1: The Seconded UK Employee
The most common international employment scenario for our clients is the UK employee posted abroad by their UK employer. The secondee typically:
- Retains their UK employment contract
- Continues to be paid by the UK entity (or has a notional UK salary that is the basis for the local salary)
- May be tax-equalised (the employer manages the total tax burden to approximate what it would be in the UK)
- May have a "host country agreement" alongside the UK contract for local employment law purposes
Pension contribution implications: If the secondee continues to receive a salary from the UK employer that is subject to UK PAYE, they have relevant UK earnings and are an RUI. They can contribute to their UK pension up to 100% of those UK earnings (subject to the annual allowance). Tax relief at the UK marginal rate is available.
If the assignment is structured so that the UK salary is suspended and replaced entirely by a local salary (a common arrangement for cost reasons), the position changes. The local salary may not be relevant UK earnings unless it is subject to UK income tax — for example, because the employee is resident in the UK for the purposes of the double taxation agreement and their overseas earnings are taxable in the UK.
Practical implication: Before going on assignment, review the payroll structure with the employer's HR, mobility, and payroll teams. The answer to "can I continue contributing fully to my UK pension?" depends critically on whether the salary arrangement produces relevant UK earnings.
Scenario 2: The Dual Contract Arrangement
Some internationally mobile employees work under two contracts simultaneously: a UK contract for their core employment and a local contract in the host country for their host-country duties. This "dual contract" or "split payroll" arrangement is common among senior executives who are genuinely responsible for both UK and local operations.
Pension contribution implications: The relevant UK earnings for pension purposes are the earnings under the UK contract that are subject to UK income tax. The local contract earnings may or may not be UK taxable income, depending on:
- Whether the employee is UK resident (resident individuals are taxable on worldwide income; non-residents only on UK-source income)
- Whether the double taxation agreement allocates the right to tax the earnings to the UK or the host country
- Whether the Overseas Workday Relief provisions apply. Following the abolition of the remittance basis and domicile-based rules from 6 April 2025, OWR is now residence-based: it is available to employees who qualify for the new 4-year Foreign Income and Gains (FIG) regime, for up to four tax years, and is capped at the lower of 30% of worldwide employment income or £300,000 per year
In a typical dual contract arrangement for a non-resident employee, only the UK contract salary counts as relevant UK earnings. Contributions based on the full combined salary would exceed the relevant UK earnings basis and the pension provider would not grant relief at source on the excess.
Scenario 3: The Employee of a Non-UK Employer
Where a UK national works for a non-UK employer — with no UK employment contract and no UK earnings — the following applies:
- Relevant UK earnings: Zero (unless there is UK-source earned income from another source)
- RUI status: Only if the person was UK resident in one of the five previous tax years
- Maximum contribution with tax relief: £3,600 gross (£2,880 net from the member, plus £720 from HMRC claimed via relief at source)
This is the "basic amount" — a safety valve that allows any UK National Insurance number holder to make a minimum pension contribution, regardless of where they live or what they earn.
The £3,600 limit is still worth using. Over five years of overseas employment, a person who makes the £2,880 net contribution each year accumulates £18,000 of personal contributions + £3,600 of government top-up = £21,600 gross in the pension. This grows tax-free in the pension wrapper and is meaningfully better than allowing the UK pension to go entirely dormant.
Employer Contributions from Non-UK Employers
A non-UK employer can contribute to a UK registered pension scheme for a UK national employee — and this is often more tax-efficient than doing nothing or than setting up a local pension arrangement.
Why this works: A pension contribution by an employer to a registered pension scheme is a "relevant benefit" that HMRC recognises. The contribution goes into the pension tax-free from the employee's perspective — the employee is not taxed on the contribution as a benefit in kind (unlike, say, a company car or private medical insurance, which are taxable benefits). The contribution counts toward the employee's annual allowance.
The employer's deduction: Whether the non-UK employer can deduct the contribution against its local corporation or income tax depends on local law. In many jurisdictions, contributions to a UK pension for an employee are an allowable employment cost — the pension is simply a form of deferred compensation. In some jurisdictions, contributions to foreign pension schemes may not be deductible locally. The employer's tax adviser in the host country should confirm the deductibility.
The employee's position: The employee benefits from the contribution growing in a UK registered pension. At retirement, they can access the pension from anywhere in the world. The employer contributions count toward the annual allowance in the same way as UK employer contributions — and if the employee has a tapered annual allowance, employer contributions count toward the adjusted income calculation.
The Five-Year RUI Grace Period in Practice
The five-year RUI provision — allowing contributions to the full annual allowance for up to five years after UK residence ceases — is one of the most underused planning opportunities for recent emigres.
Example: An employee leaves the UK in April 2024 to take up a role with an overseas employer with no UK payroll. In 2024–25, they are not UK resident and have no relevant UK earnings from their new role. However, because they were UK resident in 2023–24, they are an RUI for 2024–25. Can they contribute to their UK SIPP with tax relief above £3,600?
Not quite: the five-year RUI provision grants RUI status, but tax relief is still only available on relevant UK earnings. In this scenario, with no relevant UK earnings in 2024–25, the person cannot obtain tax relief on contributions above £3,600 — even though they are technically an RUI. The RUI status is necessary but not sufficient; you also need the UK earnings to generate relief above £3,600.
However, if the person had UK investment income, rental income from UK property, or other UK-source income: these are not relevant UK earnings (they are investment income, not earned income). Pension tax relief requires earned income.
The five-year provision is most useful where:
- The person has some UK employment income in their early years abroad (from consulting, directorships, or part-time UK work)
- The person returns to UK employment within five years and wants carry forward capacity preserved
Record-Keeping for International Contributors
Individuals who make pension contributions from abroad — especially those relying on RUI status, claiming tax relief via self-assessment, or contributing as the RUI five-year provision applies — should maintain careful records:
- Evidence of UK residence in prior years (P60s, bank statements, electoral register, HMRC correspondence)
- Payslips and P11D/P60 forms showing UK taxable earnings in the year of contribution
- Evidence of overseas employer contributions (if applicable)
- Pension contribution receipts confirming gross contributions and relief claimed
If HMRC enquires into a pension contribution made from abroad, this documentation supports the claim that the contribution was valid and that tax relief was correctly obtained.
How Global Investments Can Help
International employment creates real complexity in pension planning. The interaction of RUI status, relevant UK earnings, employer contribution structures, and the annual allowance is not intuitive, and getting it wrong can result in under-contribution (missed pension building opportunity) or over-contribution (unexpected annual allowance charge).
Our advisers help internationally mobile clients:
- Determine RUI status and relevant UK earnings in each tax year
- Structure contributions to maximise pension building during overseas postings within the correct limits
- Advise non-UK employers on contributing to UK pension schemes for UK national employees
- Coordinate UK pension contributions with local pension obligations in host countries
- Ensure carry forward from prior years is correctly calculated and documented
We advise clients internationally, wherever in the world they live and work. Whether you are newly posted abroad or have been working internationally for years, understanding your contribution entitlement is a foundational element of your retirement planning.

Frequently asked questions
5 questions
What is a 'Relevant UK Individual' and why does it matter for pension contributions?
A Relevant UK Individual (RUI) is a person who qualifies to make pension contributions with full tax relief — specifically, more than the basic £3,600 gross per year. You are an RUI if you have relevant UK earnings in the tax year, or if you were UK resident in at least one of the five preceding tax years. An employee on secondment abroad who retains a UK employment contract and receives UK taxable salary qualifies as a RUI and can contribute up to 100% of their relevant UK earnings (subject to the annual allowance). This is materially more valuable than the £3,600 basic amount available to non-RUIs.
Link to this questionCan a non-UK employer contribute to a UK registered pension scheme for an employee?
Yes. A non-UK employer can make contributions to a UK registered pension scheme (including SIPPs and occupational schemes) on behalf of an employee. The contribution must satisfy the 'wholly and exclusively for the purposes of the employer's trade' test for the employer to deduct it — which it typically does, as an employment benefit. The employee benefits from the contribution within the pension tax wrapper; the employer may or may not be able to deduct it for local tax purposes depending on the country's rules. The contribution counts toward the employee's annual allowance.
Link to this questionIf I am on secondment and receive both a UK salary and a local allowance, how much can I contribute?
The pension tax relief is calculated based on relevant UK earnings — income that is subject to UK income tax. If your UK salary is fully subject to UK PAYE, you can contribute up to 100% of that salary with tax relief. If your local allowance is not subject to UK income tax (for example, it is taxed only in the host country), it does not count as relevant UK earnings for pension contribution purposes. In a dual-contract arrangement, only the UK income element generates relevant UK earnings.
Link to this questionI worked in the UK for ten years and am now abroad. Can I still make contributions to my UK SIPP?
Yes. You qualify as a Relevant UK Individual if you were UK resident in any of the previous five tax years. This means for up to five years after leaving the UK, you can contribute to your UK SIPP as if you were resident — up to 100% of any relevant UK earnings, subject to the annual allowance. After five years of non-residence (with no relevant UK earnings), you fall back to the £3,600 basic amount (gross), grossed up from a net contribution of £2,880, available to anyone with a UK National Insurance number.
Link to this questionDoes the Overseas Transfer Charge apply to contributions I make while abroad?
No. The Overseas Transfer Charge (OTC) applies to transfers from UK registered pension schemes to QROPS — it is a charge on transfers, not on contributions. Making contributions to a UK SIPP while abroad does not trigger any transfer charge. The OTC only becomes relevant if and when you decide to transfer the accumulated UK pension to an overseas scheme.
