In brief (TL;DR): There are three transfer mechanisms for moving money from South Africa to the UK - the
SDA (no approval needed), the
FIA (requires SARS approval), and SARB
FinSurv for very large amounts. WBForex handles all three routes.
About 500,000 South Africans live in the UK. Transferring money from SA is something most expats do regularly - whether it is sending over living expenses, making a lump-sum investment, or moving savings built up over years. Knowing the rules, the allowances, and how the process works makes a real difference.
The three transfer mechanisms
1. Single Discretionary Allowance (SDA)
The SDA is the simplest route. Every South African resident adult can transfer up to the annual SDA limit per calendar year without needing any SARS pre-approval. It was doubled to R2 million per adult per calendar year in the 2026 Budget, announced 25 February 2026. It resets on 1 January each year and unused allowance does not carry over. A couple can move R4 million combined. This is the route most regular transfers take - monthly living expenses, gifts, school fees, and general top-ups.
2. Foreign Investment Allowance (FIA)
The FIA covers transfers above the SDA ceiling, allowing an additional R10 million per person per year. To use the FIA, you need SARS approval before the funds move. WBForex prepares and submits the full application on your behalf.
3. SARB FinSurv special approval
For anything above the combined SDA and FIA ceiling, a separate application goes to the South African Reserve Bank's Financial Surveillance Department, supported by a SARS Letter of Compliance. This is assessed case by case and typically applies to significant property proceeds, large inheritance transfers, or the externalisation of substantial wealth. WBForex manages this process end-to-end.
Exchange rates matter
The rate you are offered makes a meaningful difference to how much arrives in your UK account. South African commercial banks apply wider margins on international transfers than specialist forex providers. On larger transfers, the gap between what a bank offers and what a specialist offers can translate into a significant difference.

The process is simpler than it sounds
For SDA transfers, the process is typically completed same-day or next business day once documentation is in order. For FIA transfers, the main variable is the SARS processing time, which typically runs two to four weeks. WBForex handles the documentation, compliance, and execution throughout.
A worked example: an expat in Reading moving R3.5 million across a year
A typical scenario: a 38-year-old software engineer in Reading, moved to the UK three years ago, planning to externalise R3.5 million from accumulated SA savings and a recent SA property sale over the calendar year. He is a SA tax resident with clean compliance.
Q1 of the year: He uses the full R2 million SDA in one transfer in January, immediately after the calendar reset. No SARS pre-approval needed. Documentation: SA ID, proof of source (combination of payslip history and the property sale conveyancer's account), and the transfer instruction. Execution: next business day. Flat R250 SWIFT fee applies.
Q2-Q3 of the year: The remaining R1.5 million sits above the SDA, so the FIA route applies. WBForex prepares the AIT application - up-to-date SARS tax returns, source of funds pack centred on the property sale, completed AIT form. SARS processes within three weeks. Once approved, the R1.5 million externalises at the commercial rate locked at execution. Flat R250 SWIFT fee applies again on this leg.
End of year position: R3.5 million has moved from SA savings to UK current and investment accounts, across two separate execution events tied to two distinct mechanisms. Total documentation effort: one source of funds pack used for both transfers. Total fees: R500 in SWIFT charges plus the commercial conversion spread on each leg.
The point is not the maths. The point is that for a meaningful capital flow, the right answer is rarely "one big transfer" - it is "the right mechanism for each tranche, sequenced cleanly through the year".
The mistakes SA expats make
A few patterns:
- Defaulting to the SA business banker for personal transfers. Business banking systems route transfers through the same retail rate book as personal banking, but with extra friction. For personal money, the specialist route is usually cleaner.
- Not using the full SDA each calendar year. It resets on 1 January and does not carry over. If you intend to move significant capital over multiple years, using each year's full SDA before relying on the FIA reduces the SARS application burden and the timeline.
- Sending the AIT application themselves through SARS eFiling. Possible, but expat eFiling access is often blocked by lost passwords, old SA mobile numbers, or outdated registration details. A specialist preparing and submitting on your behalf removes that friction.
- Confusing the SDA's R2 million figure with the old R1 million. The doubling came in the 2026 Budget announcement on 25 February 2026. Pre-existing online articles, expat forums, and older bank policy documents still reference the old number. Always check the date of the source.
- Treating the SDA and FIA as alternatives rather than additive. They stack. You can use the full R2 million SDA AND the full R10 million FIA in the same calendar year, for a combined R12 million per adult. Couples can combine to R24 million in a single year.
Edge cases worth knowing
For transfers above the combined R12 million ceiling per adult, the SARB FinSurv route applies. This is a separate application supported by a SARS Letter of Compliance, assessed case by case. Typical scenarios: large property proceeds, inheritance externalisation, or wealth events tied to a business sale. WBForex handles this end-to-end and the timeline is longer (typically 8-14 weeks).
For SA expats who have already ceased SA tax residency, the transfer mechanics change. Capital movements after cessation are classified differently and the documentation is different. Worth working out the cessation timing relative to your planned capital flows rather than treating them as independent decisions.
For couples where one spouse has higher SDA usage than the other, planning the calendar year's transfers across both names is materially more efficient than running everything through one name. Both spouses have full allowances; both should use them.
For SA expats sending money INTO South Africa rather than out (UK pension drawdown to SA family, remittance to SA-based parents, returning UK savings before formal repatriation), the rules are different. The companion piece on returning your UK savings to South Africa covers the inbound mechanics.
A word from Peter: "Most clients overthink the mechanism question. The honest answer is usually 'use the SDA for what fits, use the FIA for what doesn't, and let us handle the SARS application'. The complexity is in the documentation and the sequencing, not in the choice of route. Get the source-of-funds pack right at the start and the rest follows."

FAQ
What is the SDA limit for 2026?
R2 million per adult per calendar year. This was doubled from R1 million in the 2026 Budget, announced 25 February 2026. The allowance resets on 1 January each year and unused allowance does not carry over. Couples can combine for R4 million per year.
Do I need SARS approval for an SDA transfer?
No. The SDA is a no-approval route - you can transfer up to R2 million per calendar year without any SARS pre-approval. You do need to confirm your source of funds and complete the standard transfer instruction, but no AIT is required.
How long does an FIA transfer take from start to finish?
For a clean application with current tax compliance, typically three to five weeks total. SARS processing of the AIT runs two to four weeks; document collation, submission, and execution add about a week on either side. The biggest variable is whether SARS raises any queries on your tax record.
Can I use the SDA and FIA in the same calendar year?
Yes - they are additive, not alternatives. You can transfer R2 million via SDA (no approval needed) and R10 million via FIA (requires AIT) in the same calendar year, for a combined R12 million per adult. Couples can stack both names for R24 million.
What happens if I need to transfer more than R12 million in a year?
You need SARB Financial Surveillance approval, supported by a SARS Letter of Compliance. This is a separate, case-by-case application typically used for large property proceeds, inheritance, or business-sale wealth events. Timeline is longer (8-14 weeks) but the process is well-established. WBForex manages this route end-to-end.
