In brief (TL;DR): The March 2026 budget doubled the
Single Discretionary Allowance to R2 million, which is a meaningful shift for young tech expats relocating from Cape Town or Stellenbosch to London. You can externalise your SA savings without needing to formally cease your SA tax residency.
The tech and corporate pipelines from South Africa to the UK and Ireland have never been busier. If you've recently moved from a tech hub like Cape Town or Stellenbosch to take up a role in London, getting your financial footing is step one.
The biggest news for young professionals transferring their savings arrived in March 2026, when National Treasury officially doubled the Single Discretionary Allowance (SDA).
What the March 2026 SDA upgrade means for you
The SDA was capped at R1 million per adult per calendar year for the better part of two decades. The 2026 Budget, announced by the Minister of Finance on 25 February 2026, doubled it to R2 million. SARB and the commercial banks implemented the new ceiling at exchange-control level in the weeks that followed, so for most people the change became real in March and April.
The mechanics matter. Your SDA does not require any form of SARS clearance. You're not waiting for a tax compliance audit, you're not submitting an Approval for International Transfer (AIT) application, you're not engaging with a SARS auditor. You're simply telling your bank you'd like to use your SDA, providing standard FICA-level documentation, and moving the money.
For most young professionals leaving SA, R2 million is more than enough headroom. A vehicle sale, accumulated savings, the proceeds of a small portfolio liquidated before you board the flight - all of that usually fits comfortably under the new ceiling. Couples have R2 million each, so R4 million between you. The allowance resets every 1 January and doesn't carry over, so there's no penalty for using a smaller portion in any given year.
Tax emigration vs keeping SA residency
A surprising number of new arrivals in London assume they need to formally cease their SA tax residency before they can move money across. That's not how it works.
If you're working in the UK on a skilled worker visa, a Global Talent visa, or a similar 3-to-5 year arrangement, SARS still treats you as an SA tax resident in most cases. You retain full access to your R2 million SDA, plus your R10 million Foreign Investment Allowance (FIA) if you need it - combined ceiling of R12 million per adult per year before you start needing SARB FinSurv approvals.
Ceasing your SA tax residency is a one-way door. It triggers a deemed capital gains event on your worldwide assets, locks you out of your SDA going forward, and complicates your position if you ever come back. It's the right call for some people. For a 28-year-old on a five-year UK contract who might be back in Cape Town in 2031, it's almost never the right call. Our piece on tax emigration vs keeping SA residency covers the question in more depth.
A word from Peter: "Many young expats think they have to formally cease their SA tax residency the moment they land at Heathrow. If you plan to return, or you're just on a skilled worker visa, maintaining your SA residency while using the new R2 million SDA is often the most efficient way to manage your cross-border wealth."
What this actually looks like in practice
A typical scenario for someone in this position runs as follows.
You sold a one-bedroom in Sea Point in late 2025 for R3.6 million. After settling the bond and paying CGT, you walk away with about R1.7 million. You've also got R350,000 in cash savings sitting in an FNB current account. You arrived in London in February 2026 on a five-year skilled worker visa. You need to move about R1.8 million across over the next few months to cover a London rental deposit, basic furnishings, an emergency cushion, and to seed a small Stocks and Shares ISA.
Because you're still an SA tax resident, your full R2 million SDA for the 2026 calendar year is available. The R1.8 million sits comfortably inside it, so no AIT required. You move it across in three tranches over April, May and June - partly to smooth out short-term Rand movement, partly because your bank's onboarding is faster on smaller amounts. Each tranche is quoted at the live commercial GBP/ZAR rate, a flat R250 SWIFT fee, and lands in your UK current account inside 24 to 48 hours of settlement.
Come 1 January 2027, your SDA refreshes. Whatever you didn't use in 2026 is gone, but you've got a fresh R2 million to play with - useful if a bonus, share vest or other windfall lands during the year.
The mistakes that catch people out
A few patterns we see often enough to call out:
- Assuming SA tax emigration is a precondition for moving money. It isn't. SDA is available to SA tax residents. Cessation is a separate, much weightier decision.
- Defaulting to your SA retail bank for the first transfer. Retail banks don't usually charge an upfront fee because the cost is hidden in the spread. The money still leaves your account, you just don't see where it went. Bank-beating rates plus a flat R250 SWIFT fee usually mean more Sterling lands in London.
- Moving everything in one shot. If your total transfer sits close to the R2 million ceiling, splitting across a year-end unlocks a second full R2 million on 1 January. Worth thinking about if your timing is flexible.
- Forgetting the SDA doesn't carry over. Used R600,000 in 2026? On 1 January 2027 you get a fresh R2 million, not R3.4 million. The unused portion expires.
- Confusing UK-earned wealth with SA SDA exposure. Once your salary lands in a Barclays or HSBC account in Sterling, that money is already offshore. RSUs vesting in London never touch your SDA. Only Rand-denominated funds still sitting in SA do.
Edge cases worth knowing about
A mid-year inheritance or share vest can push you over R2 million unexpectedly. When that happens you've got three choices: hold the surplus until 1 January and split across calendar years, combine SDA with FIA (which means an AIT application and a SARS audit window of typically four to six weeks), or do both. The right path depends on how time-sensitive the transfer is.
If you've already drawn down some of your SDA inside SA - paid an Oxford term in Sterling on a SA-issued card, taken a forex-denominated holiday - that comes off your R2 million. Worth checking with your bank before you assume the full amount is still on the table.
Bi-directional flows are a separate question. Sending Sterling back to SA - paying off a student loan, supporting a parent, contributing to an SA property - falls under SARB's inward rules, not your SDA. Your SDA only governs Rand leaving SA.
If you and your spouse are both SA tax residents, each of you has your own R2 million. There's no joint pool. The transfer comes out of each individual's SA account.
Bi-directional corridor in one place
Your financial life is split across two countries now. Money goes out (to fund your London life) and money comes back (to pay off SA obligations or support family). Two separate banking relationships is two sets of forms, two compliance teams, and two sets of fees. A specialist forex partner manages both directions through one dedicated relationship. The relocation-side logistics - the bits that aren't financial - are well covered in Adele's Pretoria to Surrey family relocation checklist, worth a read once the money side is sorted.

FAQ
Do I need to be tax-emigrated to use the R2 million SDA?
No. As long as SARS still considers you an SA tax resident, your SDA is available. Most young professionals on a UK working visa remain SA tax residents for the first few years at least. Cessation is a separate decision with significant tax consequences and isn't a route worth taking just to move savings.
Does my SDA carry over if I don't use the full R2 million this year?
No. Whatever you don't use by 31 December is gone. 1 January gives you a fresh R2 million, but nothing rolls forward.
Can my spouse and I combine our SDA into a R4 million joint allowance?
Each adult has their own R2 million, so a couple has R4 million between them per calendar year. The transfers come from each individual's SA account though - there isn't a shared pool. If only one of you holds the Rand savings, you've effectively got R2 million unless the funds are first split.
Is the R2 million SDA in addition to the R10 million FIA?
Yes. They stack. R2 million on SDA (no clearance needed) plus R10 million on FIA (requires a SARS AIT application) gives a combined ceiling of R12 million per adult per year. Above R12 million you'd need SARB FinSurv special approval and a SARS Letter of Compliance - a different conversation for a different size of transfer.
My UK employer gave me RSUs that vest in London. Does that count toward my SDA?
No. RSUs vesting with a UK employer pay into a UK brokerage or UK bank account in Sterling. That money is already offshore, never touches SA, and doesn't draw down your SDA. The SDA governs Rand leaving SA, nothing else.
