South Africa Tax Residency: The Two Tests That Decide Your Worldwide Tax Bill
South Africa taxes residents on worldwide income and non-residents only on South African-source income — so your residency status is the single most expensive question in the system. SARS applies two independent tests: the ordinarily resident test (a facts-and-circumstances "where is home" inquiry) and the physical presence test (a precise day-count formula). Meet either one and you are a resident. Here is how each works.
Test 1: ordinarily resident (the "real home" test)
This is a common-law concept, not a day count. You are ordinarily resident in South Africa if it is the country to which you would naturally and as a matter of course return after your wanderings — your usual or principal residence, your real home. Continuous physical presence is not required.
SARS and the courts weigh factors such as:
- where your family is based
- where your primary residence is located
- where your business interests are concentrated
- where you hold permanent residence or long-term immigration status
- whether your departure from South Africa was intended as permanent
- nationality, visa type abroad, property, and social ties
Because it is facts-based, there is no formula — and no way to "day-count" your way out of it. If South Africa is genuinely your home, you are ordinarily resident regardless of travel.
Test 2: physical presence (the day-count test)
This test only applies if you were not ordinarily resident at any point during the tax year. It has three cumulative requirements — fail any one and you do not meet the test:
- More than 91 days in South Africa during the current year of assessment;
- More than 91 days in South Africa during each of the five preceding years of assessment; and
- More than 915 days in total across those five preceding years.
South Africa's year of assessment for individuals runs March 1 to February 28 (February 29 in a leap year). A day counts if any part of it is spent in South Africa — arrival and departure days both count.
Practical consequence: someone newly spending time in South Africa cannot meet the physical presence test until at least six years of qualifying presence have accumulated.
Losing residency under the physical presence test
A person who is resident only by virtue of the physical presence test ceases to be a resident if physically outside South Africa for a continuous period of at least 330 full days — deemed to have ceased from the day they left.
Note the asymmetry: the ordinarily-resident test has no equivalent automatic exit. Ceasing to be ordinarily resident is a facts-and-circumstances determination (the "emigration" moment), and SARS scrutinizes it closely — many expats who believe they left remain classified as residents.
What residents vs non-residents pay
- Residents are taxed on worldwide income (subject to double-tax treaty relief and specific exemptions, such as the foreign employment income exemption with its own caps and conditions).
- Non-residents are taxed only on South Africa-source income — for example, SA employment income, SA rental income, and capital gains on SA immovable property.
Residency also affects filing: residents file annual returns on worldwide income via SARS eFiling; the tax year and provisional tax rules apply.
The treaty tie-breaker
If South Africa and another country both claim you as a resident under domestic law, the applicable double taxation agreement (DTA) tie-breaker decides — typically running through permanent home, centre of vital interests, habitual abode, and nationality, in that order. Treaty relief does not make you a non-resident under SA domestic law; it allocates taxing rights between the countries.
Common mistakes
- Assuming leaving = non-resident. Departure alone does not end ordinarily-resident status. SARS looks at where your real home remains.
- Counting only full years. The physical presence test is assessed annually against rolling six-year windows — do the arithmetic every year.
- Forgetting the 330-day rule. A long absence breaks physical-presence residency, but only at 330 continuous full days.
- Ignoring the March–February tax year. Day counts must be tallied per SA year of assessment, not the calendar year.
- Not telling SARS. Emigrants should formally address their residency status with SARS rather than simply stopping filing — silent non-filing invites queries.
Frequently asked questions
I moved to South Africa 3 years ago and stay ~200 days a year. Am I a tax resident?
Possibly under the ordinarily resident test already (if SA is now your real home). Under the physical presence test alone, not yet — you need six years of qualifying presence. Either test suffices, so get advice on the ordinarily-resident analysis.
I am ordinarily resident but work abroad 10 months a year. Does that change anything?
Not automatically — travel does not end ordinary residence. The foreign employment income exemption may shelter some foreign salary, but residency itself stands until the facts change.
How do I formally cease tax residency when emigrating?
Address it with SARS directly (there is a formal cease-to-be-resident process), keep evidence of the emigration date, new home, and severed ties — and check the DTA tie-breaker with your new country.
Do I file in South Africa if I am a non-resident with SA rental income?
Yes — non-residents are taxed on SA-source income and must file accordingly.
Where do I file?
SARS eFiling (sars.gov.za) is the standard channel for individual returns.
