South African Expat Tax: The Complete Guide for 2026

If you’re a South African living and working abroad, SARS still wants to hear from you. South African expat tax is the tax you owe to the South African Revenue Service on your foreign employment income, even when you’re earning it thousands of kilometres away from home. Since 1 March 2020, SA tax residents working overseas are taxed on foreign employment income above R1.25 million per year. Below that threshold, you can claim an exemption. Above it, you pay tax at normal South African rates.

That single rule change caught thousands of expats off guard, and six years later most South Africans abroad still don’t fully understand what they owe, what they can claim, and what happens if they get it wrong. This guide covers everything in plain English.

What Is South African Expat Tax?

South African expat tax refers to the tax that SARS levies on the foreign employment income of South African tax residents who work outside the country. Before March 2020, this income was fully exempt if you met certain day-count requirements. That changed when the government introduced a R1.25 million cap on the exemption under Section 10(1)(o)(ii) of the Income Tax Act.

Here’s what that means in practice. If you’re a South African tax resident earning a salary abroad, the first R1.25 million of that income is exempt from SA tax (assuming you qualify). Everything above R1.25 million gets added to your taxable income in South Africa and taxed at normal rates. For the 2026/2027 tax year, those rates run from 18% on the first R245,100 up to 45% on income above R1,878,600.

The exemption only applies to employment income. If you’re self-employed, a freelancer, or an independent contractor, you do not qualify for the South African expat tax exemption. This is one of the most common misunderstandings among South Africans abroad.

How South African Expat Tax Residency Works

This is the first question that matters. Your South African expat tax obligations depend entirely on whether SARS considers you a tax resident. South Africa uses two tests to determine this.

The Ordinarily Resident Test

This is the primary test and it’s subjective. SARS considers you ordinarily resident in South Africa if the country is your real home. The place you would naturally return to after your travels. Factors that SARS looks at include where your family lives, where your personal belongings are, where your financial interests are centred, and whether you intend to come back to South Africa at some point.

This is the test that catches most expats. If you’ve moved to London or Dubai or Sydney but you still own a house in Cape Town, your kids are enrolled in a South African school, and you tell everyone you plan to come back “someday,” SARS has a strong case that you’re still ordinarily resident. It does not matter that you’ve been abroad for years. We cover what this means for specific countries in our UK expat tax guide and UAE expat tax guide.

The Physical Presence Test

If you don’t qualify as ordinarily resident, SARS applies a second, objective test based on how many days you’ve spent in South Africa. You must meet all three requirements to be considered a tax resident under this test.

Requirement	Days needed	Time period
Requirement 1	More than 91 days	Current tax year
Requirement 2	More than 91 days in each year	Each of the 5 preceding tax years
Requirement 3	More than 915 days total	Across those 5 preceding tax years

You must meet all three. If you fail even one, you don’t qualify as resident under this test. A part of a day counts as a full day, so arriving at 23:55 on a flight into Johannesburg counts as one day of physical presence.

If you become a resident through the physical presence test but then leave South Africa for a continuous period of at least 330 full days, you stop being a resident from the day you left.

The Foreign Employment Income Exemption (Section 10(1)(o)(ii))

This is the exemption that most South African expats rely on. It lets you exclude up to R1.25 million of foreign employment income from South African tax per year. But it comes with strict conditions.

Who Qualifies

To claim the exemption you must tick every box on this list.

• You must be a South African tax resident
• You must be an employee (not self-employed, not a contractor)
• Your services must be rendered outside South Africa
• You must spend at least 183 full days outside South Africa in any 12-month period that falls within the tax year
• Of those 183 days, at least 60 must be continuous

The 183/60-day rule is about the exemption, not about tax residency. This is a critical distinction that trips people up constantly. Meeting the 183-day requirement doesn’t make you a non-resident. It simply qualifies you to claim the exemption on the first R1.25 million.

What Happens Above R1.25 Million

Any foreign employment income above the R1.25 million exemption is fully taxable in South Africa at your marginal tax rate. Here’s what that looks like using the current 2026/2027 brackets.

Taxable income bracket	Tax rate
R1 to R245,100	18%
R245,101 to R383,100	26%
R383,101 to R530,200	31%
R530,201 to R695,800	36%
R695,801 to R887,000	39%
R887,001 to R1,878,600	41%
R1,878,601 and above	45%

The Frozen Exemption Problem

The R1.25 million exemption has not moved since it was introduced in 2020. The 2026 Budget left it unchanged again. That means more expats are exceeding the threshold every year simply because of inflation and currency movements, not because they’re actually earning more in real terms. A salary of about R105,000 per month already puts you above the exemption. In countries like the UK, Australia, and the UAE, that’s a fairly standard professional salary for an experienced South African expat.

Double Taxation Agreements (DTAs)

South Africa has signed Double Taxation Agreements with over 79 countries. These treaties determine which country gets to tax specific types of income when you’re earning across borders. They exist to prevent you from being taxed twice on the same income.

But here’s what most expats get wrong: a DTA does not automatically exempt you from South African expat tax. You still need to file a return with SARS, and you need to actively claim relief under the applicable treaty. Having a passport stamp from another country or permanent residency abroad changes nothing on its own.

How DTAs Work in Practice

Each DTA contains “tie-breaker” rules that determine which country has the primary right to tax you. These rules look at factors like where your permanent home is, where your personal and economic ties are strongest (centre of vital interests), where you habitually live, and your nationality.

If the DTA determines that the other country has the taxing right over your employment income, South Africa must give relief. This usually comes in the form of a tax credit under Section 6quat of the Income Tax Act. South Africa won’t charge you less tax, but it will let you offset what you’ve already paid abroad.

South Africa has DTAs with most major expat destinations including the United Kingdom, Australia, the Netherlands, Germany, Canada, the United States, the UAE, and New Zealand. However, not every country has an agreement in place. If you’re in a country without a DTA, the risk of actual double taxation is real. Our guide to South Africa’s double taxation agreements covers this in more detail.

Countries With No DTA

Some popular destinations for South African expats do not have a Double Taxation Agreement with South Africa. If you’re living and working in one of these countries, you may end up paying tax in both jurisdictions with limited relief. Before you move, check the SARS DTA list to confirm whether your destination country has an active agreement.

Ceasing South African Tax Residency

If the expat tax burden becomes too heavy, or if you’ve permanently settled abroad with no intention of returning, you can formally cease your South African tax residency. This is the only way to stop SARS from taxing your worldwide income. Simply leaving the country doesn’t do it. Renouncing citizenship doesn’t do it. You need to go through the SARS process.

How to Cease Residency

The process involves updating your registration details on SARS eFiling (the RAV01 form) and submitting supporting documentation that proves you’ve permanently settled in another country. SARS will want to see evidence like a foreign tax residency certificate, proof of a permanent home abroad, employment contracts, and anything else that demonstrates your real home is no longer South Africa.

If SARS is satisfied, they’ll issue a Notice of Non-Resident Tax Status. Once you have this, only income sourced from within South Africa (like rental income from SA property) is taxable.

But be warned. There have been reports in 2026 of SARS reviewing and even withdrawing previously issued non-resident status letters. Some individuals who ceased residency years ago are being called back for re-verification. This is not common, but it’s a risk worth knowing about.

The 330-Day Rule

If you became a resident through the physical presence test (not the ordinarily resident test), you can cease residency by being physically outside South Africa for a continuous period of at least 330 full days. Your residency ends from the day you left. This does not apply if you were ordinarily resident. In that case, SARS needs evidence that you’ve genuinely abandoned South Africa as your home.

Exit Tax (Section 9H)

Ceasing tax residency triggers what’s known as exit tax. Under Section 9H of the Income Tax Act, SARS treats all your worldwide assets as if they were sold at market value on the day before you ceased residency. You don’t actually sell anything. Nothing changes hands. But SARS calculates the capital gain and taxes it. For a deeper breakdown, see our complete guide to SARS exit tax.

What Assets Are Caught

The deemed disposal applies to most capital assets worldwide. That includes listed and unlisted shares, unit trusts and ETFs, foreign property, Krugerrands and gold coins, crypto assets, and other investments. The scope is broad.

What’s Excluded

South African immovable property is excluded because SARS can still tax it after you leave (it remains SA-source income). Retirement fund interests are also excluded from the exit tax following recent amendments. South Africa retains taxing rights over retirement withdrawals through separate provisions, so there’s no need to trigger CGT on exit.

How Exit Tax Is Calculated

For individuals, 40% of the net capital gain is included in taxable income. The maximum effective CGT rate for individuals is 18%. The annual exclusion for the 2026/2027 tax year increased to R50,000 (up from R40,000). Your primary residence exclusion is R2 million if the gain is below R2 million (R3 million for gains above that).

The 2026 Spousal Donation Loophole Closure

Until February 2026, a common strategy for managing exit tax involved staggered emigration between spouses. One spouse would cease residency first. The remaining spouse would then donate significant assets to the non-resident spouse tax-free under the longstanding inter-spousal exemption, reducing the combined exit tax bill.

The 2026 Budget killed this strategy. From 25 February 2026, the spousal donations tax exemption only applies when the receiving spouse is still a South African tax resident. If your spouse has already ceased residency, donations to them can now trigger a 20% donations tax on top of any exit tax consequences. If your emigration planning is based on advice from before this date, it may already be outdated.

South African Expat Tax and Provisional Payments

Most South African expats working abroad don’t have PAYE deducted by their foreign employer for SARS. That makes you a provisional taxpayer. SARS expects you to make two provisional tax payments per year (in August and February) to cover your estimated liability on foreign income above the R1.25 million exemption.

Failing to submit provisional tax returns or underpaying can result in penalties and interest. Many expats don’t realise they have this obligation until SARS contacts them, and by then the interest has been running for years.

You remain a provisional taxpayer until you formally cease tax residency. There is no automatic opt-out.

Filing Your Tax Return as an Expat

As a South African tax resident abroad, you are required to file an annual income tax return with SARS. You need to declare your worldwide income, including your foreign employment income, even if most of it falls under the R1.25 million exemption. Understanding how to file correctly is one of the most practical parts of managing your South African expat tax obligations. You claim the exemption on the return itself.

What You’ll Need

• Your IRP5 or foreign equivalent showing employment income earned
• Proof of days spent outside South Africa (travel records, passport stamps, boarding passes)
• Details of taxes paid in the foreign country (for DTA relief claims)
• A foreign tax residency certificate if you’re claiming treaty benefits
• Records of any South African source income (rental, interest, dividends)

The South African tax year runs from 1 March to 28 February. For the current 2027 year of assessment, the period is 1 March 2026 to 28 February 2027. Tax season filing dates are announced annually by SARS, usually opening in July.

Retirement Funds and Pensions

South African expats who have ceased tax residency and want to withdraw their retirement annuity or pension must wait at least three years after formally becoming a non-resident. This is the 3-year lock-in rule. It applies to lump sum withdrawals from South African retirement funds.

The good news is that retirement fund interests are not subject to exit tax (following recent amendments to Section 9H). However, when you eventually withdraw, SARS will tax the lump sum according to the retirement fund withdrawal tax tables, not the normal income tax tables. These are separate schedules with their own rates and thresholds.

For expats who plan to continue contributing to a South African retirement annuity while abroad, the deduction limit for the 2026/2027 tax year is 27.5% of the greater of your remuneration or taxable income, capped at R430,000 per year (increased from R350,000).

What About the 2026 Budget Changes?

The 2026 Budget Speech on 25 February 2026 made several changes relevant to expats and tax residents.

Change	Detail	Impact on expats
Tax brackets adjusted 3.4% for inflation	First bracket adjustment since 2023/24	Slightly reduces tax on income above the R1.25M exemption
Primary rebate increased to R17,820	Up from R17,235	Small reduction in tax payable
Tax-free threshold raised to R99,000	Under 65 taxpayers	Minimal impact for most expats
CGT annual exclusion raised to R50,000	Up from R40,000	Small relief on exit tax calculations
Retirement fund deduction cap raised to R430,000	Up from R350,000	Relevant for expats still contributing to SA funds
Single discretionary allowance doubled to R2 million	For transferring money offshore	Helpful for pre-emigration fund transfers
Spousal donations exemption restricted	Only applies if receiving spouse is a SA tax resident	Major impact on couples doing staggered emigration
R1.25 million exemption unchanged	Frozen since 2020	More expats exceed the threshold every year

Common South African Expat Tax Mistakes

Thinking that leaving South Africa ends your tax obligation. It doesn’t. You remain a tax resident until you formally cease residency through SARS. Simply not filing doesn’t make the obligation go away. It just means penalties and interest are stacking up in the background.

Confusing the 183-day rule with tax residency. The 183-day rule applies to the foreign employment income exemption. It does not determine whether you’re a tax resident. Tax residency is determined by the ordinarily resident test or the physical presence test (91/91/915 days). These are different things.

Assuming a DTA means automatic exemption. Double Taxation Agreements don’t apply automatically. You need to file a return, apply the relevant treaty, and claim the relief. Having citizenship or permanent residency in another country does not remove your SA tax obligation on its own.

Not declaring foreign income. SARS requires you to declare all worldwide income on your tax return, including the income that falls under the R1.25 million exemption. You claim the exemption on the return. You don’t just leave the income off.

Ignoring provisional tax. If your foreign employer doesn’t deduct PAYE for SARS (and they won’t), you’re a provisional taxpayer. That means two payments per year and a separate provisional return. Missing these results in penalties.

Should You Cease Tax Residency or Stay Resident?

This is the question every South African expat eventually asks. There’s no one-size-fits-all answer because it depends on your income level, your assets, your plans for returning, and which country you’re in.

Staying resident makes sense if your foreign employment income is below R1.25 million, you plan to return to South Africa eventually, you have minimal capital assets that would trigger exit tax, or you want to continue contributing to South African retirement funds with full deductibility.

Ceasing residency makes sense if your income is well above R1.25 million and the annual tax bill is significant, you’ve permanently settled abroad with no realistic plan to return, the exit tax on your assets is manageable, and the country you live in has a DTA with South Africa that would give you treaty relief anyway.

The decision is complicated by the 2026 spousal donation changes. If you’re part of a couple planning to emigrate, the sequence and timing now matter more than ever. Getting professional advice before you start the process is not optional.

Where to Get Help

South African expat tax sits at the intersection of SA tax law, foreign tax law, exchange control regulations, and international treaties. It’s not something most people can handle alone, especially when exit tax and DTAs are involved.
