Workplace and Occupational Pensions for Internationally Mobile Employees

For the majority of UK workers, workplace pension provision is relatively straightforward: auto-enrolment through an employer into a group personal pension or master trust, with minimum contribution levels and HMRC-registered scheme protections. For the internationally mobile worker — employed by a UK company but based abroad, working for an overseas employer, or self-employed across multiple jurisdictions — the picture is fragmentary, inconsistent, and often inadvertently neglected.

Understanding where gaps in pension provision arise, what obligations apply, and what options exist is essential for internationally mobile employees who want to avoid approaching retirement with inadequate savings.

UK Auto-Enrolment: When It Applies Abroad

The Basic Auto-Enrolment Framework

UK auto-enrolment (introduced in 2012 and now fully implemented) requires all UK employers to automatically enrol eligible workers into a qualifying pension scheme and make minimum contributions. Eligibility conditions are:

• Aged between 22 and state pension age
• Earning above the auto-enrolment earnings trigger (£10,000 per year in 2026/27)
• "Ordinarily working in the UK"

The third condition is the critical one for internationally mobile workers.

"Ordinarily Working in the UK"

HMRC and The Pensions Regulator define "ordinarily working in the UK" broadly as where the UK is the habitual place of work — where the employee principally performs their employment. An employee who works entirely overseas, based in a host country, is not ordinarily working in the UK and is therefore not subject to UK auto-enrolment.

An employee who works in the UK as their base but travels extensively abroad — or who is temporarily posted abroad — is generally still considered to be ordinarily working in the UK, and auto-enrolment continues to apply.

The distinction matters in practice: an employee posted from London to Dubai for two years retains UK auto-enrolment status if the UK remains their contractual base. An employee directly employed by an overseas operation, whose employment is governed by local law, does not.

Opting Out

Auto-enrolment is not compulsory in the sense that employees can opt out. However, employees must be re-enrolled every three years — and failure to opt out of a re-enrolment window can inadvertently trigger pension scheme membership. For those holding Fixed Protection certificates, this is critical: automatic re-enrolment into a pension scheme can invalidate the Fixed Protection and permanently lose the higher PCLS entitlement. Monitor re-enrolment dates carefully.

Defined Benefit Pensions and International Postings

DB Pensions: A Rapidly Declining but Still Important Resource

Defined benefit (DB) occupational pension schemes — which provide a guaranteed income in retirement linked to salary and service — have become very rare in the private sector. Most were closed to new members during the 2000s and 2010s. However, many internationally mobile workers from the public sector (NHS, civil service, teaching, local government, armed forces) or from long-tenured private sector roles in industries that historically offered DB schemes may have preserved DB entitlements.

What Happens to a DB Pension When You Work Abroad

For active members of a DB scheme who are then posted abroad:

• If the employer maintains the UK employment contract and the employee remains a scheme member, active DB accrual may continue (though employer and employee contribution obligations during the posting should be addressed in the posting agreement).
• If the posting results in a change of employer entity — even within the same corporate group — the employee may become a deferred member, with accrual ceasing.

For deferred DB pensions (those with a former employer), the position is simpler: the deferred pension continues to grow in line with the scheme's rules (statutory revaluation at the lesser of CPI inflation and a cap) and will be paid from the scheme's normal pension age regardless of where the member lives.

Should You Transfer a DB Pension Abroad?

For most people, no. DB pensions are extraordinarily valuable — the guarantee of an index-linked income for life, with spouse's benefit, is difficult to replicate in a money purchase environment. Transferring a DB pension to a SIPP or QROPS involves:

• Receiving a CETV, which may understate the true value
• Converting a guaranteed income into an invested fund subject to market risk
• Losing the spouse's benefit (unless specifically replicated)
• Requiring regulated financial advice (mandatory for transfers above £30,000)

Regulated advice will in most cases result in a recommendation NOT to transfer. There are cases where transfer is appropriate — significant health impairment reducing life expectancy, or very large transfer values for those with sophisticated investment capability — but these are the exceptions.

International Employer Pension Plans

The Multi-Employer International Model

Large multinationals with significant internationally mobile workforces often operate International Pension Plans (IPPs) — sometimes called Global Employee Benefit Plans. These are pension arrangements typically registered offshore, in jurisdictions such as:

• Guernsey or Jersey (common for UK-connected IPPs)
• Cayman Islands (for global US-connected organisations)
• Singapore (for Asia-Pacific regional plans)
• Luxembourg (for European-focused plans)

IPPs are designed to be portable across multiple jurisdictions — an employee moving between the UK, US, Singapore, and UAE over a 20-year career can accumulate pension savings in a single IPP without the complications of managing multiple local pension schemes.

Tax Treatment of IPPs

UK personal tax relief is not available on contributions to IPPs (because they are not UK-registered pension schemes). However:

• Employer contributions to IPPs may be made on a tax-advantaged basis in the relevant offshore jurisdiction.
• Many countries in which IPP members are resident have tax treaty provisions that give favourable treatment to international pension contributions and benefits.
• IPP income on retirement may be taxed under the relevant DTT at relatively favourable rates.

For employees in companies that offer an IPP, the plan is typically the best available pension provision for international mobility. It is worth understanding the plan's terms, the vesting schedule, and the investment options.

The Absence of IPP for Smaller Employers

Many internationally mobile workers are employed by smaller UK companies without sophisticated international HR infrastructure. These employees often find that when they go abroad, no employer pension provision follows them. The employer may:

• Stop contributing to a UK group personal pension (if the employee is no longer UK-based)
• Make contributions to a local scheme in the host country (which may have limited benefit at the end of the posting)
• Simply have no pension arrangement for the overseas posting period

This gap — which can last years — is one of the most common sources of pension deficit for internationally mobile workers. Options for filling the gap include:

• Maintaining personal contributions to a UK SIPP (up to the £3,600 gross minimum, or more if UK earnings remain subject to UK income tax)
• Enquiring about whether employer contributions to the UK scheme can be maintained contractually
• Considering a QROPS if genuinely permanently relocated to a country where this makes sense

The International Pension Centre

HMRC and DWP jointly operate the International Pension Centre — a government service that assists with:

• State pension claims for those living abroad
• National Insurance enquiries for overseas workers
• International employer pension scheme recognition (ROPS/QROPS status)

Internationally mobile workers whose overseas employer wants to contribute to a UK-recognised pension arrangement may need to explore whether the employer's overseas scheme qualifies as a ROPS (Recognised Overseas Pension Scheme) or whether contributions can be routed through a UK-registered scheme.

Filling the Coverage Gap: Individual Options

For internationally mobile workers without adequate employer pension provision overseas, the practical options are:

UK SIPP contributions: Up to £3,600 gross per year for non-residents, or up to 100% of relevant UK earnings if those earnings remain subject to UK income tax. Continuity of SIPP membership maintains carry forward eligibility for large contributions in future UK tax years.

Voluntary NI contributions: Maintaining State Pension entitlement through voluntary Class 3 contributions is often the most cost-effective pension "contribution" available to someone abroad with no overseas employer provision. (Voluntary Class 2 contributions for periods spent abroad were abolished from 6 April 2026 for most people, so Class 3 — approximately £18.40 per week in 2026/27 — is now the standard route; narrow exceptions remain, such as those treated as self-employed in the UK under a social security agreement.)

ISA before departure: Those who know they are moving abroad can use ISA allowances in the final UK tax year (you cannot contribute to an ISA once non-UK resident, but the ISA continues to grow tax-free and can be maintained indefinitely). This is a cash buffer rather than a pension, but relevant to overall retirement planning.

How Global Investments Can Help

Global Investments advises internationally mobile employees — both within corporate groups and individually — on the pension implications of overseas postings and relocations. We review existing provision (DB preserved pension, UK SIPP, IPP), identify coverage gaps, and recommend strategies to maintain retirement savings continuity during overseas assignments.

For employees negotiating international posting terms, we can advise on what pension provisions to request as part of the expatriate package.
