Do I really pay an Exit Tax when I leave SA?

Leaving South Africa Permanently? Here’s What You Need to Know About Exit Tax

If you’re planning to leave South Africa permanently, one of the key tax issues you need to be aware of is the exit tax. This tax comes into play when you are no longer considered a South African tax resident — and it can have important financial implications.

Many people only discover exit tax during the process of formal emigration. Understanding how it works — and why it exists — is crucial to avoid unexpected costs or compliance issues after your departure.

What Is Exit Tax?

Exit tax, officially known as the deemed capital gains tax upon ceasing tax residency, is a tax that applies when an individual formally ceases to be a South African tax resident. At that point, SARS treats certain assets as if they have been sold, even if no actual sale has taken place. This is called a “deemed disposal.”

The reason for this is simple: SARS wants to ensure it collects tax on any capital gains made while you were still a South African tax resident. Once you become a resident of another country, South Africa generally loses its right to tax future gains on most of your worldwide assets.

Why the Exit Tax Is Calculated the Day Before You Leave

The exit charge is calculated as if you sold your applicable assets on the day before your tax residency ends. This timing is deliberate. It ensures that the tax liability falls fully within the period when you were still a tax resident of South Africa.

If the tax were calculated on the day your residency ends, you would already be a non-resident — which could create ambiguity about which country has taxing rights. By setting the date one day earlier, SARS locks in its jurisdiction and closes off your South African tax affairs cleanly and clearly.

When Does It Apply?

Exit tax applies when you formally cease to be a South African tax resident. This doesn’t happen automatically when you leave the country — it depends on your intention and whether you still meet the tests for residency, such as the “ordinarily resident” test or the physical presence test.

To trigger the process, you must inform SARS that you’ve ceased tax residency, typically through your tax return or a dedicated declaration.

What Is Included?

Exit tax applies to most worldwide capital assets that you own at the time you cease residency. These may include investments, shares, foreign property, cryptocurrency, and business interests.

However, not all assets are subject to exit tax. Two key exclusions are:

• South African immovable property, such as land or residential real estate. These remain subject to South African tax when sold, regardless of your residency.
• Retirement funds in South Africa. These are taxed separately when you withdraw the funds in the future.

Example: How It Works in Practice

Let’s say Thuli, a long-time resident of South Africa, decides to relocate to the United Kingdom permanently in 2025. She informs SARS that she is ceasing her South African tax residency.

Thuli owns shares in an international company that she originally purchased for R100,000. On the day before her tax residency ends, those shares are worth R250,000. Even though she has not sold the shares, SARS will treat them as if they were disposed of for R250,000, creating a deemed capital gain of R150,000.

In South Africa, 40% of this gain is included in an individual’s taxable income. That means R60,000 will be added to Thuli’s tax return and taxed at her applicable marginal rate.

Declaring and Paying the Tax

Once you notify SARS of your change in residency, your final tax assessment will include any capital gains from the deemed disposals. If there is tax payable, you must settle it or make payment arrangements with SARS.

If you retain any South African assets — such as property — you’ll still be taxed in South Africa on those assets under local rules when income is earned or when they are eventually sold.

Final Thoughts

Exit tax is an important and often overlooked part of the emigration process. It’s not designed to penalise those who leave the country, but rather to ensure that any gains made during your time as a South African resident are properly taxed.

With early planning and professional advice, the process can be managed efficiently and with minimal stress. Being informed about how and why exit tax works will help you leave South Africa on a clean financial footing and avoid surprises after you’ve moved abroad.
