SA Unit Trusts After You Emigrate: What Generally Happens

“I’ll just leave my unit trusts where they are and deal with it later” is one of the more common things said about investment accounts in SA emigration circles — and it’s fair enough, except that “later” arrives faster than people expect. What happens to SA unit trusts after you emigrate usually starts the day before your South African tax residency officially ends.

Does emigrating trigger a tax event on unit trusts?

Generally, yes. South Africa’s exit tax creates a deemed disposal of your worldwide assets at market value on the day before your tax residency ceases — a notional sale, not an actual one, which is exactly why it catches people off guard: there’s no real cash proceeds sitting there to pay the resulting tax from. South African immovable property is excluded from this and stays in the SA tax net regardless, but a unit trust holding, as a financial asset rather than property, generally isn’t excluded. The capital gains mechanics for individuals work out to a 40% inclusion rate against your marginal rate (up to 45%), giving a maximum effective rate around 18%, with an annual exclusion reported at R40,000 for 2025 — that figure isn’t confirmed for 2026, so check the current amount before you calculate anything.

What tax applies once you’re no longer resident?

This is genuinely unclear from what’s confirmed here. Dividends withholding tax and interest withholding tax on SA-sourced income you keep receiving after ceasing residency are flagged in the source material as areas needing dedicated, separate attention rather than something fully worked through in general emigration guidance. Don’t assume either that everything is exempt once you’ve left, or that nothing changes — get the specific mechanics confirmed for your holdings.

Will your platform still hold you?

Not something general research can answer, because it varies platform to platform. Some investment platforms restrict certain products to South African residents only; others don’t, or apply extra reporting once your registered address changes to Canada. Whether continuing to hold SA funds from Canada is even an option for your specific unit trusts is a question for that platform directly, in writing, before you leave rather than after — a five-minute call now is cheaper than an unwind you didn’t plan for later.

And what does Canada want to know?

That’s a Canadian tax question sitting on the other side of this whole process, and it’s outside what South Africa-focused research can responsibly answer. Canada generally expects tax residents to report foreign holdings above certain thresholds, but the specific form, threshold and mechanics for a South African unit trust are a conversation for a Canadian accountant with cross-border experience rather than something a general immigration blog should guess at.

None of this is a reason to panic about your investments — it’s a reason to get the exit-tax mechanics and the platform’s own policy confirmed properly before you go, rather than finding out on the way out. Cape2Canada’s guides cover the immigration side of the move; this is squarely where a cross-border tax adviser earns their fee.
