Offshore Investments Held Through SA Platforms, Explained Honestly

Every tax season, some version of the same misconception does the rounds among South Africans planning a move — one worth getting explained properly: offshore investments held through SA platforms are already offshore, so surely they won’t be touched when I emigrate. It feels logical — the underlying assets sit in New York or London funds, not on the JSE. It’s also not how South African tax law treats the moment you actually leave.

It comes down to one distinction that matters more than where the underlying assets sit: whether you are still a South African tax resident, rather than where the fund manager’s offices are.

The rule that overrides the platform

When you cease to be a South African tax resident, Section 9H of the Income Tax Act triggers a deemed disposal of your worldwide assets at market value, valued the day before residency ends. It’s a notional sale — no cash actually changes hands — which is exactly why it catches people out. There’s a tax bill on a transaction that didn’t happen, and the only asset class excluded from this is South African immovable property. An offshore-fund investment sitting inside a South African-domiciled investment platform is not immovable property. It’s caught, same as a JSE share or a local bank balance.

What that deemed disposal actually costs

The mechanics, for individuals: gains are included at 40%, taxed at your marginal rate up to 45%, which works out to a maximum effective rate of roughly 18%. There’s an annual exclusion too — R40,000 was the figure for the 2025 tax year; treat that as the reference point rather than a confirmed 2026 number, and check the current figure with a tax practitioner before you rely on it for planning.

Getting the value out afterwards

Once residency has genuinely ceased — through the ordinarily-resident test, 330 continuous days physically outside South Africa, or a tie-breaker clause in the Canada–South Africa tax treaty — moving the resulting money out runs through the ordinary exchange control channels. The single discretionary allowance now sits at R2 million a year, doubled from R1 million in 2026, and doesn’t need a tax clearance PIN. The foreign capital allowance goes further, up to R10 million per person per calendar year, but requires a SARS Tax Compliance Status PIN — and it’s a per-year allowance rather than a lifetime one, which trips people up in the other direction.

Where our research runs out

What we can’t responsibly give you here is the layer below that — the detail inside the layered structure many SA investors already hold: how a specific feeder-fund structure compares to holding offshore assets directly, or the exact residency and reporting rules a particular platform applies to a departing client’s account. Those details are product-specific and change by provider, and naming them without a confirmed source would be a guess dressed up as advice. A platform account manager or a registered tax practitioner who’s actually looked at your holdings is the right source for that layer.

The one question worth asking before the next tax season

Not “is my money offshore already” — it almost certainly is, in the sense you mean. The real question is whether your tax residency has actually ceased under one of the tests above, because that’s the switch that turns a live portfolio into a deemed disposal. Get that answer from a registered tax practitioner before assuming the platform has already done the work for you.
