South Africa Tax for Expats: Residency, Worldwide Income and What SARS Actually Wants From You

By The Expat Club · Updated October 2026

You are a South African tax resident if South Africa is your real, settled home (the ordinarily-resident test) or if you meet the physical-presence test: more than 91 days in the current tax year and in each of the five tax years before it, plus more than 915 days in total over those five. Residents are taxed on worldwide income, non-residents only on South African-source income. The 183-day figure people often quote is not a residency test: it is one of the conditions of the foreign employment income exemption.

Before you work out how much tax you will pay, you need to know whether SARS treats you as a tax resident. That answer decides whether your worldwide income, the exemptions and double taxation come into play at all.

Who actually taxes you: SARS, in brief

The South African Revenue Service (SARS) administers all national taxes, including personal income tax. Unlike some countries where tax residency is tied purely to citizenship or a visa category, South Africa uses its own residency tests that apply regardless of your nationality or immigration status. You can be a tax resident on a work visa, a tax resident with permanent residence, or, less intuitively, a tax resident with no residence permit at all, if you meet the tests below. The reverse is also true: holding a South African visa does not automatically make you a tax resident.

This residence-based approach is a different starting point from the US system, which taxes citizens on worldwide income regardless of residency: our guide to moving to South Africa from the USA covers how the two systems interact for Americans specifically.

The day counts in the physical-presence test below follow South Africa's tax year, which runs from 1 March to 28 February rather than January to December.

The two residency tests

SARS decides whether you're a tax resident using two independent tests. Meeting either one is enough to make you resident for tax purposes.

1. The ordinarily-resident test

This is a facts-and-circumstances test, not a day count. SARS and the courts look at where your real, settled home is: where your family lives, where your habitual routine plays out, where you'd return to after being away. Someone who has moved their household, enrolled children in local schools, and built their day-to-day life in South Africa is likely ordinarily resident even if they still travel extensively for work. There's no bright line here, which is exactly why it catches people out: it's a qualitative judgment, and it can apply even to someone who hasn't hit any particular day threshold.

2. The physical-presence test

This one is mechanical and much easier to calculate. Broadly, you become tax resident under this test if you are present in South Africa for:

• more than 91 days in total during the current tax year, and
• more than 91 days in total during each of the preceding five tax years, and
• more than 915 days in total during those same preceding five tax years.

All three conditions have to be satisfied together. Because the test looks back over the five preceding tax years, someone arriving with no earlier time in South Africa cannot meet it until their sixth tax year at the earliest, so in those first five years only the ordinarily-resident test can make them resident. The test is designed to catch people who have spent years quietly building up South African days without ever formally settling.

Someone who splits time fairly evenly between South Africa and another country over a five-year stretch should actually run the numbers rather than assume they're in the clear.

Worth knowing: these two tests are independent. You can fail the physical-presence test on day count alone and still be caught by the ordinarily-resident test if South Africa is clearly your real home. New arrivals often focus only on counting days and miss this.

What tax residency actually means for your money

If you're a South African tax resident, SARS taxes your worldwide income, not just what you earn locally. That includes foreign salary, foreign rental income, foreign investment returns and foreign business income, in addition to anything sourced in South Africa. This is the point that surprises people most: it doesn't matter where the money was earned or where it sits, only where you are resident.

If you're a non-resident, the scope narrows considerably: SARS only taxes South African-source income. A non-resident with a rental property in Cape Town pays SA tax on that rental income; their salary from an employer overseas for work done outside South Africa and their offshore investment portfolio stay outside SARS's reach. Buying a home as a non-resident brings its own costs and paperwork, which we cover in our guide to buying property in South Africa as a foreigner.

Pay for work you do while you are in South Africa is treated differently. Even as a non-resident with an overseas employer, that pay is taxable in South Africa unless a double-taxation agreement gives relief. Treaty relief usually depends on three conditions together: you are in South Africa for no more than 183 days in total in any 12-month period, your employer is not a South African resident, and your pay is not borne by a permanent establishment your employer has in South Africa.

For the 2026/27 tax year (1 March 2026 to 28 February 2027), SARS's rates for individuals start at 18% on the first R245,100 of taxable income and reach 45% on taxable income above R1,878,600. Because of the primary rebate, tax only becomes payable once taxable income passes R99,000 for under-65s. The residency question isn't academic: it decides whether your foreign income is part of that calculation at all.

Relief for tax residents: the exemption and DTAs

Being taxed on worldwide income sounds alarming, but two mechanisms soften it considerably for people genuinely working abroad or with cross-border ties.

The foreign employment income exemption allows South African tax residents who work outside the country for their employer to exclude a portion of that foreign employment income from SA tax, currently capped at R1.25 million a year. The day-count conditions are specific: SARS requires more than 183 full days outside South Africa in a 12-month period, and, within that same period, at least one continuous stretch of more than 60 full days outside the country. Both legs are required together, not just the 183-day total, which is a detail that trips people up.

Income above the R1.25 million cap is taxed in South Africa, with a credit typically available for foreign tax already paid on it. The exemption is for employees only, so freelancers and independent contractors cannot use it, and SARS also excludes people employed in the public sector. It covers only work done outside South Africa, so pay for days you work from inside the country is not exempt.

Separately, South Africa has double-taxation agreements (DTAs) with a large number of countries. A DTA doesn't remove SA tax across the board, but it sets out which country may tax each kind of income, sometimes giving one country the sole right, and provides a credit mechanism so the same income isn't taxed twice at full rates in both jurisdictions. If you're a tax resident here with income or assets in a DTA country, the specific treaty terms, not general assumptions, determine the outcome, and they vary meaningfully from one country to the next.

SARS publishes the treaties in force, split into Africa and the rest of the world, and the UK, Ireland, the USA, Germany, Australia and Portugal all have one. If you are moving from Portugal, our guide to moving to South Africa from Portugal covers the fuller visa, tax and shipping picture.

Provisional tax: the one most employees have never heard of

If all your income comes through a South African employer via PAYE, you're mostly done once your payslip deductions are correct. But if you have income that isn't taxed at source (foreign rental income, freelance or consulting income, investment income above certain thresholds), you likely need to register as a provisional taxpayer and pay estimated tax twice a year, ahead of the annual assessment. This catches out a lot of new arrivals who assume tax is purely an annual filing event; for provisional taxpayers, it isn't.

The first payment is due by 31 August and the second by the last business day of February, with an optional top-up by the last business day of September. If you have no business income, you are excluded from provisional tax if your taxable income is below the tax threshold, or if your taxable interest, foreign dividends, rental income and pay from any employer not registered with SARS for PAYE come to R30,000 a year or less in total. That includes a salary from an overseas employer without South African PAYE.

Leaving South Africa: tax emigration and exchange control

If you eventually leave South Africa for good, there's a formal process for "ceasing tax residency" with SARS (sometimes called tax emigration) that changes your status from resident to non-resident going forward and can trigger a capital gains tax event on deemed disposal of certain assets at the point you cease residency. Our guide to financial emigration versus tax emigration covers that process in more detail.

Ceasing tax residency is a technical area with real financial consequences, and it interacts with exchange control rules administered separately by the South African Reserve Bank (SARB), which governs how funds move into and out of the country. Anyone planning a longer-term exit, not just a holiday abroad, should get this properly modelled before making the call.

Common mistake: assuming that leaving South Africa physically is the same as ceasing tax residency. It isn't: the two can be out of sync, sometimes for years, with tax consequences accruing the whole time.

Getting it right

South African tax residency turns on where your life is really based and on how many days you spend in the country, not on the visa you hold, and the worldwide-income consequence of getting it wrong, in either direction, can be significant.

The rules above are a starting map, not a substitute for professional advice: cross-border tax depends on your own income sources, your home country's tax rules and any applicable DTA. If you are unsure which side of the line you fall on, a cross-border tax specialist who knows both South African rules and your home country's rules can look at your actual dates and income before you file, or before you assume you don't need to.
