In brief (TL;DR): Moving from SA to the UK involves a financial checklist on both sides. Get your SARS affairs in order before you leave, transfer your initial landing funds, and set up UK banking early - the admin is manageable if you tackle it in the right order.
Moving from South Africa to the UK involves a lot more than packing boxes. There is a fair bit to sort on the SA side before you go, and another list of things to get in order once you arrive. This checklist covers the main ones.
Before you leave South Africa
SARS and tax:
- Make sure all SA tax returns are up to date - SARS will not process any transfer applications while you have outstanding returns
- Update your SARS RAV01 registration details with your new UK address and contact details
- Decide whether to complete cessation of tax residency before you go or wait until you have settled - there are arguments for both approaches depending on your asset position
- Tell your SA bank you are moving abroad - they may need to update your account classification
Financial accounts:
- Keep your SA bank account open - you will need it for receiving any SA income and making SA payments
- Review your SA retirement annuity and pension arrangements - if you plan to access them under the three-year rule, the clock starts when SARS confirms your cessation
- Transfer your initial landing funds to your UK account using your SDA before you leave - this is the fastest way to get money across without any SARS pre-approval
Property:
- If you are selling your SA property before you leave, be aware that proceeds above the SDA will require a Foreign Investment Allowance (FIA) application
- If you are keeping the property and renting it out, you will still have SA-sourced rental income to declare even after cessation
When you arrive in the UK
The general checklist above tells you what to do; the timeline tells you when. The clearer your sequencing, the less last-minute scrambling. Here is the rough structure most relocating SA families benefit from.
12 weeks before flight. Start the SARS-side work first because it takes the longest. Get your tax returns current. Update the RAV01 with your future UK address (even if provisional). Have a conversation with WBForex about your specific situation - whether you will use the SDA before departure, whether your funds need FIA treatment, and whether cessation makes sense to initiate now or hold. If you own SA property and plan to sell, the marketing process needs to start here.
8 weeks before flight. UK banking research. Most high street banks have specific "moving to the UK" account opening processes for non-residents, but some require proof of UK address first. Digital banks (Monzo, Starling) typically open accounts faster with a passport and a UK delivery address. If you have an SA RA or preservation fund, decide what your access strategy is - encash later, leave it, or roll into a preservation structure. Children's school applications are time-sensitive at this point too.
4 weeks before flight. Execute your SDA transfer - move your initial Sterling landing funds to your new UK account (or to your spouse's UK account if yours is not open yet, or to a UK family member as a temporary holding step). UK accommodation should be confirmed; provide that address to SARS via the RAV01 update if not already done.
1 week before flight. Final SA bank balance sweep into your transfer pool. Confirm UK bank account is funded and accessible. Print or digitise key documents you may need on landing: SA tax compliance status, SA bank statements (last 6 months), proof of source of funds, UK accommodation confirmation, schools confirmation if applicable.
First week after arrival. Apply for your National Insurance number through Jobcentre Plus. Register with HMRC if employed or self-employed. Pick up any UK bank cards that were posted to your UK address pre-arrival. Set up the ongoing WBForex relationship for monthly transfers, FIA applications, or any planned SA-to-UK capital flow.
Months 1-3 in the UK. Settle the rest of the admin: GP registration, council tax, utility accounts. Any remaining SA capital you plan to move runs through the established framework - SDA where it fits, FIA above that. RA decisions can wait; the three-year clock has not started yet.
The timeline is not rigid. Some families work to a 6-month runway; others have 4 weeks. What matters is sequencing the SARS work first because it has the longest lead time, the UK-side admin second, and the actual money movement last.
The mistakes families make
A few patterns:
- Leaving SARS-side work until the final two weeks. SARS does not move quickly. Outstanding returns, missing RAV01 updates, or any compliance gap can block your AIT and stall your departure plans. Start 12 weeks out.
- Trying to open a UK bank account only after arrival. Some banks will refuse without proof of UK address; others will process but slowly. Starting the conversation pre-departure (with a UK accommodation address ready) usually gets you a faster account opening.
- Closing all SA accounts before departure. You will need an SA account for receiving any SA income (rental, dividends, pension), making SA payments (any residual bills, family support), and as the source for the SDA/FIA transfers themselves. Keep at least one active.
- Not using the SDA before leaving SA. It is the fastest, no-approval route to move your landing funds. Burn the SDA pre-departure if you have funds to move; save the FIA and AIT for the larger capital flows that follow.
- Underestimating the timeline for UK admin from a distance. NI number, HMRC registration, GP registration - these are simple individually but take time as a stack. Most relocating families take 6-8 weeks to feel fully "set up" administratively in the UK.
Edge cases worth knowing
For couples where one spouse moves first and the other follows months later, run the SARS-side work for both spouses in parallel, even if the physical relocation is staged. UK admin work can wait until the second spouse arrives.
For families with school-age children, the UK school application timeline often drives the relocation date. School year alignment (UK academic year starts September) may add months to the planning window. Worth checking school admission dates before locking in flights.
For relocating SA family business owners (where SA business proceeds form part of the relocation capital), the SA-side capital flow is more complex - SARB FinSurv may be involved, particularly above the R12 million per adult combined ceiling. Start that conversation 6+ months out.
For SA families with pets, the pet-import timeline (rabies titre testing, microchipping, paperwork) often runs to 4-6 months pre-departure. The pet timeline frequently becomes the binding constraint, more than financial admin.
For SA expats from specific cities or with specific profiles, our companion pieces on Pretoria to Surrey family relocation, Cape Town to London corporate relocation, Fourways to Wandsworth landing checklist, and tech expats moving to the UK and Ireland go deeper on city or profession-specific aspects.
A word from Adele: "The families who handle the relocation cleanly are the ones who start the SARS-side work three months out, not three weeks. Everything downstream depends on the SARS profile being clean. We see this every relocation cycle - the families who panic in the final week are usually the ones who left the tax returns and the RAV01 updates until the last moment. It is the most preventable kind of stress."

FAQ
How early should I start the SARS-side work before my move?
12 weeks before your planned departure is the sensible minimum. Outstanding returns need to be filed, the RAV01 may need updating, and your overall compliance status needs to be clean before any AIT processing can run. Starting earlier gives you more flexibility on the timing of capital movements.
Can I keep my SA bank account open after I move to the UK?
Yes, and most expats do. You will need an SA account for receiving any SA-source income (rental, dividends, pension), making any SA-side payments, and as the source for ongoing SDA/FIA transfers. Closing all SA accounts creates friction; keep at least one active.
Do I have to use the SDA before I leave South Africa?
No, the SDA stays available for as long as you remain a SA tax resident (which you are until formal cessation). But using it pre-departure is often the fastest way to get your landing funds across without any SARS pre-approval. Most relocating families execute the SDA transfer in the final 4 weeks before flying.
When does my UK tax obligation start?
You become a UK tax resident on the date you meet HMRC's statutory residence test - usually based on days spent in the UK and whether you have a UK home. For most relocating families, this is the date of arrival or shortly after. HMRC's online residence test guide helps confirm your specific position.
Can WBForex handle the transfer process if I am not yet in the UK?
Yes. The transfer setup can happen entirely from SA pre-departure, using your SA bank account as the source and your UK bank account as the destination (once that is open). Most clients set up the framework in the final 4-6 weeks before flying, then execute their initial transfer just before or just after arrival.
