For years, South Africans relocating abroad have focused on a relatively straightforward question:
Have I ceased to be a South African tax resident?
That question has not changed. What appears to be evolving is how the South African Revenue Service (“SARS”) tests the factual timeline behind the answer.

Recent interactions with SARS suggest that the tax authority’s interest is not only in whether a taxpayer is resident or non-resident, but whether the taxpayer can substantiate the timeline that supports that conclusion.
This distinction may seem subtle. Yet it has significant implications for South African expatriates leaving the country, as well as foreign nationals establishing lives and careers in South Africa.
It is also becoming increasingly relevant as taxpayers approach the 2026 filing season, where residency positions and their effective dates may result in different tax consequences before and after the relevant residency date.
Says Delano Abdoll, Legal Manager: Cross-Border Taxation at Tax Consulting South Africa:
“Historically, tax residency disputes often focused on the end result. Increasingly, we are seeing SARS focus on the chronology that led to that result. The question is no longer simply whether a taxpayer became resident or non-resident, but whether they can support the timeline underpinning that conclusion.”
Tax Residency Has Never Been Just About Status
South African tax residency is often discussed as though it were a binary concept.
Either a taxpayer is resident or non-resident.
In reality, tax residency is also a question of timing.
A person may become ordinarily resident from a specific date and, similarly, may cease to be ordinarily resident from a specific date. SARS’ administrative processes likewise require taxpayers to declare the date on which they ceased South African tax residency or, where applicable, the date on which they became tax resident again.
The importance of effective dates is therefore not new.
What is becoming more apparent is the level of scrutiny SARS is applying to the facts supporting those dates.
SARS’ Growing Focus on the Tax Residency Timeline
Of late, SARS correspondence indicates an increasing focus on the chronology of a taxpayer’s circumstances rather than simply the taxpayer’s ultimate conclusion.
In one recent verification process, SARS requested that the taxpayer provide the exact date on which South African tax residency was originally triggered.
That request is noteworthy.
Rather than focusing solely on when residency ceased, SARS sought to establish the taxpayer’s broader residency history.
In another matter, SARS rejected a non-resident verification request stating that the date on which a taxpayer ceases to be resident under a Double Tax Agreement (“DTA”) is not simply the date on which the taxpayer left South Africa, but rather the date on which the requirements for exclusive residence in the other country are satisfied.
In a separate verification process involving a taxpayer who had relocated abroad, SARS requested evidence from the foreign tax authority confirming the taxpayer’s status as a tax resident on the precise date on which the taxpayer claimed exclusive residence in the foreign jurisdiction arose.
Taken together, these interactions point towards a common theme: SARS is placing increasing emphasis on the timing and sequence of events relevant to a taxpayer’s residency position.
The Departure Date Is Not Always the Relevant Date
A common misconception among South African expatriates is that tax residency automatically ends when they physically leave South Africa.
From a practical perspective, that assumption is understandable. A taxpayer relocates overseas, secures accommodation, commences employment and begins building a life elsewhere.
From a tax perspective, however, the position is often more nuanced.
A taxpayer may leave South Africa on a specific date, commence foreign employment on another, obtain foreign residence rights months later and only thereafter satisfy the requirements for exclusive residence in another country under a DTA.
Similarly, a foreign national arriving in South Africa may enter the country on one date, commence employment on another and only later establish the degree of permanence necessary to become ordinarily resident.
As a result, several dates may become relevant:
While these dates may coincide, they often do not.
The challenge lies in determining which date is legally relevant and whether sufficient evidence exists to corroborate it.
Why This Matters Ahead of the 2026 Filing Season
The timing of this trend is particularly relevant as taxpayers prepare for the 2026 tax filing season.
Individuals who became South African tax residents during a year of assessment, ceased South African tax residency during a year of assessment, or relied on a DTA to establish exclusive residence in another country may need to carefully consider the effective date of that change and how it should be reflected in their tax returns.
In many cases, different tax consequences may apply before and after the relevant residency date.
The taxpayer’s filing position is therefore only as strong as the factual and documentary evidence supporting the date on which that residency change is said to have occurred.
Taxpayers should ensure that the dates reflected in their returns align with both the available evidence and the legal basis for the position adopted.
Why Getting the Date Wrong Matters
The determination of the correct residency date can among other things, affect:
In many cases, SARS and the taxpayer may ultimately agree on the outcome.
The dispute may instead centre on the timeline that led to that outcome.
The Real Question
For years, the residency debate largely focused on a single question:
“Are you a South African tax resident?”
Now, another question seems to be becoming just as important:
“Can you prove the timeline that supports your answer?”
For expatriates, foreign nationals and globally mobile individuals alike, maintaining a clear and well-documented residency timeline may become increasingly important as SARS continues to scrutinise the facts underpinning both the commencement and cessation of South African tax residency.
