South Africa tax residency: the 91-day rule
South Africa treats you as a tax resident at 91 days in the tax year (1 March – 28 February) — but the day count is only the part we can calculate. It is one of South Africa's tests, not the whole rule (see the others below). Source: South African Revenue Service (SARS), last reviewed 2026-05-27.
91 days isn't the only route — South Africa can also treat you as resident on non-day grounds (ordinarily resident test, most fixed and settled home / principal residence, centre of personal and economic interests / intention). See every test below.
Spend 91 days or more in South Africa during the tax year (1 March – 28 February) and it will generally treat you as a tax resident for that period.

How does South Africa count days for tax residency?
According to South African Revenue Service (SARS), you become a tax resident of South Africa once you spend 91 days or more there in the tax year (1 March – 28 February). Because the count is per calendar year, it resets every 1 January and days from a previous year do not carry over — though a single stay that spans New Year is split across two years’ totals.
Physical presence test — current year (91 days)
91 days · the tax year (1 March – 28 February)Spend 91 days or more in South Africa during the tax year (1 March – 28 February) and it will generally treat you as a tax resident for that period.
Physical-presence resident requires ALL of: 91+ days in the current year of assessment, 91+ days in EACH of the 5 preceding years, AND 915+ days aggregate over those 5 years. The 91-day current-year trigger is the first gate. SA tax year runs 1 Mar–28 Feb. Ordinary residence is an independent trigger.
What else makes you a tax resident of South Africa?
The day count is only one route. South Africa can also make you a tax resident through any one of the following — regardless of how few days you spend there. These don't depend on a day count, so Yuravia can't track them for you; weigh them against your own situation.
Ordinarily resident test
The PRIMARY, day-count-independent residency test (applied before the physical presence test): a person is resident if South Africa is the country to which they would naturally and as a matter of course return after their wanderings - their usual/principal/most fixed and settled home - determined on a facts-and-circumstances, common-law basis with no day threshold.
Most fixed and settled home / principal residence
A core factor within the ordinarily resident enquiry: where the individual's real, fixed and permanent home and habitual abode is located, regardless of physical days spent there in any given year.
Centre of personal and economic interests / intention
Facts considered in the ordinarily resident enquiry include the person's settled intention, family and social ties, location of assets and business interests, habits and mode of life, and where their life is centred - none of which depend on a day count.
South Africa at a glance
- Tax year
- 1 March – 28 February (29 February in a leap year). The South African year of assessment for individuals runs 1 March to the end of February; e.g. the 2026/27 year is 1 March 2026 to 28 February 2027.
- How days are counted
- Yes — under proviso (A) to the "resident" definition, "a day includes a part of a day," so a calendar day (00:00–24:00) with any presence counts as a whole day, and both the arrival day and departure day (per passport) are included; days merely in transit (no formal entry through a port of entry) are excluded.
- What residency means
- South African tax residents are taxed on their worldwide income (credit given for foreign taxes), while non-residents are taxed only on South-African-source income. Residency arises via the common-law "ordinarily resident" test OR the objective physical-presence test (more than 91 days in the current year of assessment AND more than 91 days in each of the 5 preceding years AND more than 915 days aggregate across those 5 years).

Frequently asked questions
How many days can I stay in South Africa without becoming a tax resident?
According to South African Revenue Service (SARS), South Africa treats you as a tax resident at 91 days in the tax year (1 March – 28 February) (the "Physical presence test — current year (91 days)"). Staying under that is necessary but not sufficient — a permanent home, family, or your centre of vital interests can make you resident on fewer days.
Is the day count the only way to become a tax resident of South Africa?
No. Beyond the day count, South Africa can treat you as resident through ordinarily resident test, most fixed and settled home / principal residence, centre of personal and economic interests / intention — any one of these can apply even if you stay well under 91 days. They don't depend on counting days, so confirm them against your own circumstances.
What counts as a day of presence in South Africa?
In most jurisdictions any day on which you are physically present — including the arrival and departure days — counts as a full day. Treating both as counted is the conservative assumption. Always confirm the exact rule with South African Revenue Service (SARS).
