🇿🇦 Tax residency in South Africa

South Africa runs two residency tests, and neither of them is the 183-day rule you know from other countries. The first is "ordinarily resident": a facts-based question about whether South Africa is your real home, the place you naturally return to. If SARS concludes it is, you are resident from the start, regardless of days. The second is the physical presence test, built on a 91-day pattern rather than a single-year count: it looks at spending 91 or more days in South Africa in the current tax year and in each of the preceding five tax years, with further aggregate conditions SARS publishes. The practical takeaway: it is a multi-year pattern of returning, not one long stay, that trips this test, and the number to watch is 91, not 183.

The ordinarily-resident test is the subjective one, and the usual ties feed it: a house that functions as your permanent base, a spouse or minor children living in South Africa, a registered business run from there. Those suggest permanence and commitment, and they can make you resident long before any day pattern completes.

Residency brings worldwide taxation. SARS taxes residents on income wherever it is earned, under a progressive scale whose top marginal rate is 45%. For a remote worker paid from abroad, that entire income is in scope once you are resident.

The one significant softener is the foreign employment income exemption: a South African tax resident who earns employment income for work performed abroad can qualify to have up to about ZAR 1.25 million of that income per tax year exempt, subject to days-worked-abroad conditions. Two sharp edges: it covers employment income only, so freelancers, business owners, and investors get nothing from it, and the cap means high earners still pay South African tax on the excess.

On double taxation: South Africa has an income tax treaty in force with the United States. US citizens file US returns on worldwide income wherever they live; the treaty and the US foreign tax credit rules are what prevent the same income being taxed twice. For the UK, Germany, or any other home country, relief depends on the specific agreement in force between that country and South Africa; SARS publishes the treaty list, and that is the reference to use. A treaty limits double taxation; it does not erase a South African liability once you are resident.

A local accountant who works with expats earns the fee when your situation involves foreign income plus South African ties, property, a business structure, or the foreign employment exemption. Getting the residency classification and the exemption conditions documented correctly is the difference between a clean filing and a SARS dispute.

Watch the 91-day pattern and the ordinarily-resident test; South Africa does not need 183 days to claim you.
