South Africans who have packed up and moved abroad are discovering that cutting ties with the taxman is becoming a great deal harder. The South African Revenue Service has sharpened its scrutiny of expats who claim to have ceased their tax residency, and the burden of proof is landing squarely on the individual.
Prove it, and prove when
Tax practitioners say the question SARS now asks is no longer simply whether someone became a non-resident, but whether they can support the exact timeline behind that conclusion. A filing position, in other words, is only as strong as the documentary evidence behind the date on which residency is said to have ended.
That is a problem for the many South Africans who left years ago. After a decade or more abroad, the paperwork that pins down when and how a person stopped being “ordinarily resident” — leases, employment contracts, travel records, proof of a permanent home elsewhere — is often lost or scattered. Advisers increasingly find themselves reconstructing a client’s history from fragments, a process that drags out timelines and racks up costs.
Why it matters
The cessation of tax residency is not automatic. South Africans must formally declare the change to SARS, and getting it wrong carries real consequences. Residents are taxed on their worldwide income, so a person who believes they have exited the system but cannot satisfy SARS may find their foreign salary, investments and even capital gains pulled back into the South African net.
The end-to-end process can now take up to six months depending on complexity, and trying to cease residency more than ten years after leaving is possible but painful. With Budget 2026 having already signalled a tougher stance on expats’ foreign income, the message from Pretoria is clear: leaving the country is one thing, leaving the tax base is quite another.
For the growing number of South Africans working in the Gulf, the UK and Australia, the practical takeaway is unglamorous but important — keep every document that proves where and when you built your life abroad.
