SA Expats in the UK: Retirement Planning and Pension Considerations

South African expats in the UK often have retirement money sitting in SA from years of employment there, alongside whatever they are building up in the UK. Managing savings across two jurisdictions takes some planning, but it is very manageable once you understand what you are working with.

Types of SA retirement savings

Retirement Annuities (RAs): Individual retirement savings plans, similar to UK SIPPs. Contributions are tax-deductible in SA. This is the most common type of SA retirement fund expats hold.

Pension Funds: Employer-sponsored plans from previous SA employment. Many expats have funds sitting untouched from jobs they left years ago.

Provident Funds: Similar to pension funds but with different tax treatment on withdrawal.

Preservation Funds: Used to hold pension or provident fund savings when you changed jobs in SA. These consolidate old employer funds into a single vehicle.

Accessing your SA retirement savings from the UK

Age 55 or over: You can access your RA regardless of your tax residency status.

Under 55, non-resident for three or more years: You can access your RA under the three-year rule once you have formally ceased your SA tax residency with SARS and three uninterrupted years have passed.

Under 55, still a SA tax resident: You generally cannot access your RA early, except for limited savings pot withdrawals under the Two-Pot system introduced in September 2024.

Your UK workplace pension

If you are employed in the UK, you will be automatically enrolled in a workplace pension scheme. UK pension contributions attract income tax relief at your marginal rate, so it is worth making the most of it. Your UK pension and your SA retirement savings are entirely separate - contributing to one does not affect the other.

The SA-UK Double Taxation Agreement

South Africa and the UK have a Double Taxation Agreement (DTA) that prevents you from being taxed twice on the same income. However, the way RA withdrawals are treated under the DTA depends on your residency status at the time of withdrawal. A UK-based tax adviser can confirm your specific position.

A worked example: a couple in their late forties mapping cross-border retirement

A typical scenario: a couple in their late forties, settled in Surrey since 2019. He spent 18 years working for a Johannesburg corporate before the move and has a R2.4 million Allan Gray RA plus a R650,000 preservation fund from a previous employer. She spent 12 years in SA financial services and has a R1.1 million Sanlam RA. Both are now in UK employment with workplace pensions auto-enrolled.

Step 1: take stock. They map out what sits where. Roughly R4.15 million in SA retirement vehicles, plus three years of UK workplace pension contributions across both employers. The SA money is locked under standard RA rules until age 55 (or earlier under the three-year rule if cessation happens).

Step 2: cessation decision. They sit with WBForex and a UK tax adviser to think through whether to cease SA tax residency now or hold. Their picture is settled in the UK; they own a Surrey home; both work in UK jobs. Cessation makes sense. It also starts the three-year clock against the SA RAs.

Step 3: parallel growth. While the three-year clock ticks down on the SA side, the UK workplace pensions continue to build with UK marginal-rate tax relief. There is no integration of the two systems; they grow independently. The Allan Gray and Sanlam RAs continue to compound inside SA, tax-free until access.

Step 4: access window opens. Around mid-2029 (three years after SARS confirms cessation), the SA retirement vehicles become accessible. They have options: encash and externalise (subject to SA withdrawal tax and any UK tax), or leave the funds in SA to keep growing until age 55. The three-year rule creates the option; it does not force action.

Step 5: the long view. By the time they reach age 60 (around 2038 in this scenario), they will have: UK workplace pensions accessible under UK rules, SA RAs accessible under the three-year rule (or under standard age-55 rules), and the option to externalise SA proceeds to the UK whenever it suits. The cross-border retirement is not complex once each piece is understood.

The example shows the value of mapping early. Couples who only think about SA retirement vehicles when they want immediate access are typically too late to optimise the timing.

The mistakes SA expats make

A few patterns:

• Assuming UK and SA retirement vehicles interact. They do not. Your UK workplace pension and your SA RA are independent vehicles, with independent rules, independent tax treatment, and independent access timelines. Contributing to one does not affect the other in any meaningful way.
• Forgetting old employer pension funds. Many expats have R200,000-R600,000 sitting in a previous employer's pension fund from a job they left a decade ago. These funds are absolutely still yours, but they sit untouched and unconsolidated until you do something about them.
• Treating the UK workplace pension as optional. The auto-enrolment opt-out path exists, but opting out usually means walking away from employer matching contributions plus tax relief. That is real money you are turning down.
• Ignoring SA preservation fund consolidation. If you changed jobs in SA before moving to the UK, your pension contributions sit in a preservation fund. Consolidating multiple preservation funds (or rolling them into your RA) often simplifies the eventual access picture.
• Not getting UK-side tax advice on planned SA withdrawals. The DTA prevents double taxation in principle, but the practical UK tax treatment of an encashed RA depends on specifics. Worth getting a UK adviser to model the outcome before you trigger the encashment.

Edge cases worth knowing

For expats who moved to the UK and have since changed UK employers, you may have multiple UK workplace pensions sitting with different providers (one for each job). Consolidating these into a single SIPP is often cleaner for long-term management.

For expats with SA spouses who have not yet moved (a phased family relocation), the SA-side retirement vehicles belong to whoever earned them. Joint planning is sensible but the access rules apply per individual.

For UK-resident expats who have started a UK business (limited company), employer contributions from your own company into a SIPP can be a meaningfully tax-efficient way to build UK retirement savings beyond the workplace pension framework. Worth modelling with a UK accountant.

For SA expats considering an eventual return to South Africa (the Coming Home cluster), the question is reversed: how do UK pensions transfer or interact once you are SA-resident again. The companion piece on what happens to your UK pension when you move back to SA covers that scenario.

For the encashment mechanics specifically (timing, SARS process, tax tables), our companion piece on RA encashment and the three-year rule walks through the operational detail.

A word from Adele: "The retirement question is one of the most emotionally loaded conversations we have with clients. You spent years building up that SA money. The instinct is either to leave it alone forever or to access it immediately. Neither is usually right. What works is mapping out what you have, when you can access it, and what your retirement actually needs to look like. Once that is clear, the SA side often becomes a more peaceful part of the planning rather than a worry. We focus on the mechanics; the planning conversation is one to have with a qualified UK adviser."
