If you're searching for what you need to sort out financially before moving from the UK to South Africa, the honest answer is: more admin than you'd like, spread across two tax systems, and most of it easier to handle before you leave than after. None of it is complicated on its own. The problem is usually that nobody hands you the full list, so things get missed — an ISA left open, HMRC never told, a will that still only covers UK assets.

This is that list. It's organised into three stages: what to sort before you leave the UK, what needs doing in your first few months in South Africa, and what becomes an ongoing habit once you're settled. None of it is personal advice — every situation is different enough that the specifics need a proper conversation — but it's a solid starting map of what to be thinking about.

Before you leave the UK

Tell HMRC you're going. If you're leaving the UK to live abroad, HMRC needs to know, generally via a form completed when you file your final UK tax return (or separately if you don't normally file one). This is what starts the clock on your UK tax residency status changing. Get the timing wrong and you can end up straddling two systems for longer than necessary.

Work out what happens to your UK bank accounts. Some UK banks are comfortable keeping accounts open for non-residents; others will close them or restrict them once your address changes. Worth checking with each provider directly rather than assuming.

Check your ISA. You can generally keep an existing ISA open once you leave, but you typically can't pay new money in once you're no longer UK tax resident, and the tax-free wrapper only really means something for UK tax purposes. Big enough topic to deserve its own read — see our full piece on what happens to your UK ISA when you move abroad.

Don't forget your UK pension. Whatever you hold — workplace pension, personal pension, or SIPP — it stays a UK asset wherever you live; South Africa isn't a jurisdiction UK schemes can transfer into. It's worth knowing what you hold and whether it's still working for you before you go, rather than leaving it untouched for years. We've covered this in detail separately: what actually happens to your UK pension when you move to South Africa.

Get a handle on exchange control basics. South Africa has rules governing how money moves in and out of the country, and they work differently depending on your residency status and how the money is classified. This is genuinely one of those areas where the general shape is easy to describe but the specifics depend entirely on your circumstances — worth understanding broadly before you move, and worth getting proper guidance on before you act.

Review your protection cover. Life cover, income protection, and critical illness cover bought in the UK don't always travel well — some policies exclude claims once you're resident abroad, others simply lapse. Check the wording before you assume anything carries over.

Sort your UK tax position for the year you leave. Splitting a tax year between UK and South African residency has its own rules, and getting it wrong can mean paying more tax than necessary in either country. This is a genuine "speak to a tax advisor" situation rather than something to work out from a blog post — the rules are detailed and depend on dates, income sources, and ties to the UK.

Update your will — or at least flag that you'll need to. A UK will doesn't automatically stop working when you move, but it may not deal sensibly with assets you acquire in South Africa, or with South African succession law. This is worth putting on the list now even if you action it after you land.

Your first few months in South Africa

Open a South African bank account. You'll generally need this fairly quickly for day-to-day life, and most banks will ask for proof of address, identification, and sometimes a visa or residency document. Requirements vary by bank, so it's worth checking what a given provider needs before you arrive if you can.

Understand your new tax residency position. South Africa taxes residents on worldwide income, with relief mechanisms for income already taxed elsewhere. Whether and when you become tax resident here depends on physical presence and other tests — again, general shape only; the specifics need a tax advisor who can look at your actual situation.

Register for local healthcare cover. South Africa's public healthcare system exists, but most expats and working South Africans use private medical scheme cover. Sorting this early avoids a gap in cover, and pre-existing condition waiting periods are usually shorter the sooner you join a scheme after arrival.

Think about how you'll move money going forward. Once you're earning or drawing an income in one country and spending in another, currency movement stops being a one-off event and becomes an ongoing part of your financial life. This is a bigger topic than a checklist bullet can cover properly — worth understanding as you settle in, and worth planning for deliberately rather than reacting to exchange rates as they move.

Start a South African will (or update your existing one properly). Once you have assets, accounts, or property in South Africa, it's worth having a will that specifically covers them under South African law, ideally working alongside whatever you have in the UK rather than replacing it. Expats often assume one will "covers everything" — it frequently doesn't.

Locate your important documents. Marriage certificates, UK pension statements, National Insurance number, existing policy documents — the kind of paperwork that's easy to leave behind and painful to request from overseas once you need it for something official.

Ongoing, once you're settled

Review your full financial picture as a whole, not as separate UK and SA pieces. A UK pension, a South African retirement annuity, cash in two currencies, and cover in two countries can each make sense individually and still add up to something disorganised. Worth stepping back periodically and looking at the whole picture together.

Keep your currency exposure under review. Where your savings and investments sit — sterling, rand, or a mix — matters more the longer you live here, and what suited you in year one may not suit you in year five.

Revisit your tax residency status if your circumstances change. Time spent back in the UK, a change in where your income comes from, or a change in family circumstances can all shift your position. This isn't a one-time decision.

Check in on cover and wills every few years. Life changes — a new property, a growing family, a change in health — and cover or estate planning arranged years ago doesn't always keep pace automatically.

Where this fits together

None of these steps are complicated in isolation. The difficulty is usually that they touch two countries, two tax systems, and sometimes two currencies at once, and it's easy for one piece to fall through the cracks simply because nobody was looking at the whole picture. A UK pension left untouched, an ISA nobody checked, a will that only covers half your assets — these are rarely disasters, but they're the kind of thing that's far cheaper to sort out properly than to unwind later.

Our free offshore guide covers the broader basics of investing and moving money as an expat, and is a reasonable starting point if you're still early in the process. If you're British specifically, the guide for British expats goes deeper on UK residency, ISAs, pensions and domicile — the things that change most when you leave the UK. If you're already partway through a move — or trying to work out which of these applies to you — that's exactly the kind of conversation a short introductory call sorts out faster than piecing it together yourself.

Frequently asked questions

Do I need to tell HMRC I'm moving to South Africa?

Yes — generally via a form completed with your final UK tax return, or separately if you don't normally file one. This starts the clock on your UK tax residency status changing.

Can I keep my UK ISA after moving to South Africa?

You can generally keep an existing ISA open, but you typically can't pay new money in once you're no longer UK tax resident — and the tax-free wrapper only really means something for UK tax purposes.

Can I transfer my UK pension to South Africa?

No — South Africa isn't a jurisdiction UK pension schemes can transfer into. Your pension stays a UK asset wherever you live, but it can be reviewed, old schemes consolidated, and how it's invested brought under control.

Do I need a South African will?

Once you have assets, accounts or property in South Africa, it's worth having a will that specifically covers them under South African law — ideally working alongside your UK will rather than replacing it.
