Understanding Section 9H and Why Getting Your Departure Wrong Could Cost You a Fortune
The Tax Bill Nobody Sees Coming
If you are considering leaving South Africa permanently – or you have already moved abroad and are thinking about formalising your tax emigration – there is one concept that blindsides more people than any other: exit tax.
It sounds like something you would deal with at the airport. It is not. Exit tax is a capital gains tax event triggered the moment you formally cease to be a South African tax resident, and for many people it represents the single largest tax liability they will ever face.
Under Section 9H of the Income Tax Act, when you cease tax residency, SARS treats certain of your worldwide assets as if they were sold on the day before your departure. You do not actually sell anything. Nothing changes hands. But SARS calculates the capital gain as if you had disposed of those assets at market value, and you are liable for capital gains tax on the result.
The logic from SARS’s perspective is straightforward: while you are a South African tax resident, you are taxed on your worldwide income. When you leave, they lose the ability to tax you on gains from foreign assets. So they settle the account on the way out.
The logic may be straightforward. The bill is often anything but.
What Gets Caught in the Net
Exit tax casts a wide net. It applies to virtually all capital assets that would be subject to capital gains tax if you actually sold them. That includes shares and equities – listed and unlisted, South African and foreign. It includes offshore investment portfolios, unit trusts, and ETFs. It includes property you own in another country. It includes interests in foreign trusts and partnerships. It includes cryptocurrency holdings. It includes just about anything that has appreciated in value and sits outside South Africa’s borders.
There is one major exclusion: South African immovable property. Because SARS can still tax you on gains from South African property even after you become a non-resident, it does not need to trigger exit tax on those assets. But everything else – from your global share portfolio to an investment property you own in London or Sydney – is potentially in scope.
The deemed disposal values your assets at their market value on the day before cessation. If your assets have appreciated over the years – and if you have been investing wisely, they almost certainly have – the resulting capital gain can be substantial. We are not talking about a few thousand rands. For people with meaningful offshore portfolios, the exit tax bill can run into the hundreds of thousands. In some cases, into the millions.
Why the Numbers Shock People
Here is where the maths gets uncomfortable. For individuals, 40% of the net capital gain is included in your taxable income, where it is taxed at your marginal income tax rate. The maximum effective capital gains tax rate for individuals is currently 18%.
That might not sound devastating until you start running actual numbers. If you have an offshore share portfolio with an unrealised gain of R5 million, your included capital gain at 40% is R2 million. After the annual exclusion of R50,000 (increased in the 2026 Budget), R1,950,000 gets added to your taxable income. At a marginal rate of 45%, the exit tax on that single asset class is approximately R877,500.
And that is just shares. Add in foreign property gains, offshore unit trusts, and other investments, and the total can escalate rapidly. We have seen cases where people who considered themselves modestly wealthy discovered an exit tax liability that fundamentally changed their emigration planning.
The 2026 Budget did increase the annual CGT exclusion to R50,000 and the primary residence exclusion to R3 million. These provide some relief at the margins, but for anyone with a diversified global portfolio, they barely make a dent in the overall exposure.
The point is not to scare you out of emigrating. The point is that this is not a number you want to discover after the fact.
The Spousal Trap Just Got Worse
Until February 2026, one of the most common strategies for managing exit tax was built around the spousal donations tax exemption. One spouse would cease residency first. The remaining resident spouse would donate significant assets to them – tax-free under the longstanding inter-spousal exemption – before also leaving. This effectively reduced the combined exit tax liability by shifting assets before the deemed disposal was triggered.
The 2026 Budget killed this strategy overnight. The spousal donations tax exemption now only applies where the receiving spouse is a South African tax resident. If your spouse has already ceased residency, donations to them may trigger a 20% donations tax on top of any exit tax implications.
For couples who were part-way through a staggered emigration – one spouse already out, the other preparing to follow – the rules changed under their feet. What was a legitimate and widely used planning tool became a potential tax trap with a single Budget announcement.
This is not ancient history. This happened on 25 February 2026. If your emigration planning is based on advice that predates that date, it may already be dangerously out of date.
Timing Is Not a Detail – It Is the Whole Game
The date you cease tax residency determines the valuation date for the deemed disposal. That single date dictates the market value of every asset in scope, which dictates the capital gain, which dictates the tax bill. If your assets happen to be at a peak on that date, you pay more. If markets have pulled back, you pay less.
The timing also starts the three-year clock for accessing your retirement annuity – a completely separate but equally important consideration that interacts with your exit tax planning in ways most people do not anticipate until it is too late.
And since the 2026 Budget, timing matters even more for couples. The sequence in which you and your spouse cease residency, and the timing of any asset transfers between you, now has direct tax consequences that did not exist a month ago.
Getting the timing right – or wrong – can mean a difference of hundreds of thousands of rands. This is not an exaggeration. We have seen it happen. A few weeks of poor timing on a cessation date should not cost someone a fortune, but it does when the planning is not done properly.
Why This Is Not a DIY Exercise
Exit tax sits at the intersection of South African tax law, exchange control regulations, international tax treaties, and the tax laws of your destination country. Each of these domains is complex on its own. Where they overlap is where the expensive mistakes happen.
We regularly speak to South Africans who attempted to manage their cessation of residency based on information they found online – blog posts, forum discussions, advice from friends who went through the process years ago. The information was not necessarily wrong when it was written. But the rules change constantly, and the 2026 Budget alone introduced multiple changes that invalidated strategies people had been relying on.
The other problem with the DIY approach is that exit tax does not exist in isolation. It interacts with your retirement fund access timeline, your exchange control position, your ongoing tax obligations in your new country, and potential double taxation issues. Getting one element wrong can create a cascade of consequences across all the others.
This is specialist territory. It requires current knowledge, cross-border expertise, and an understanding of how the South African system interacts with the tax regime in your destination country. It is not something you can piece together from Google searches and WhatsApp groups.
The Cost of Waiting
Every month you delay formalising your tax position is a month of uncertainty. It is a month where your asset values could change – for better or worse – without you having any control over the timing of your deemed disposal. It is a month where the regulatory environment could shift again, as it did dramatically on 25 February 2026. And it is a month where you are not using your SDA allowance to strategically position funds offshore before cessation.
The people who come through the exit tax process in the best shape are the ones who planned six to twelve months ahead. They had time to review their asset positions, optimise their timing, coordinate with tax professionals in their destination country, and ensure their SARS profile was completely clean before triggering the cessation.
The people who come through it worst are the ones who left it until the last minute – or worse, tried to sort it out after the fact.
