Sold your home under South Africa's new R3 million CGT exclusion? Here's what to do with the proceeds
Capital Gains Tax (CGT) — the tax on profit when you sell an asset like property — just became more forgiving. That relief is real and worth understanding properly, but it's the smaller question. The larger one is what happens to the money it frees up.
The R3 million exclusion, in plain terms
Effective 1 March 2026, the capital gains tax exclusion on a primary residence increased from R2 million to R3 million. This is not R3 million of the selling price — it's R3 million of the profit (the capital gain) made on the sale. If your home sold for R4 million and you originally paid R2 million for it, the gain is R2 million, and the entire amount now falls within the exclusion — no capital gains tax at all, where the old R2 million threshold would have left it fully covered too. The real difference shows up on larger gains: a R2.5 million profit, for example, previously had R500,000 taxable under the old threshold; under the new one, the entire gain is exempt.
The date that actually matters
The R3 million exclusion applies based on when your sale agreement became legally binding — not when the transfer registers at the deeds office, and not when you receive the proceeds. If the agreement was signed and binding before 1 March 2026, the previous R2 million exclusion still applies, even if transfer only goes through months later. Sellers who signed just before the cutoff and are still waiting on transfer are a genuine edge case worth checking carefully rather than assuming the higher figure applies by default.
What the change is actually worth
At the top effective capital gains rate of 18%, the extra R1 million of exclusion is worth up to R180,000 in saved tax for a seller whose gain is large enough to use the full amount. On a R2.5 million gain specifically, the old threshold left R500,000 taxable — roughly R86,800 in tax at the top rate — while the new threshold exempts the entire gain. The relief scales with the size of the gain, so it matters most for sellers in strong-performing suburbs where long-term appreciation had pushed profits above the old R2 million line.
Once the tax bill is smaller — what to actually do with the extra capital
The tax relief is genuinely useful, but it's still the smaller question. The larger one is what the total proceeds — not just the tax saved — should actually do once the sale closes. For most sellers, that's the point where a chunk of capital that used to be illiquid, tied up in a property, suddenly needs a real decision: how much stays liquid for the next purchase or as a reserve, and how much can be deployed for growth rather than parked.
This is exactly where a large property-sale windfall is most often under-used — treated purely as "money to keep safe" rather than capital that, once the immediate housing need is settled, can genuinely be put to work. The right split depends on what else the seller has and what they need the money for next, but the default of leaving all of it in a low-yield holding account while the decision gets postponed is the one outcome worth actively avoiding.
Where Caban fits
We work with individuals deploying meaningful capital — from a property sale, a retirement payout, or a business exit — who want a genuine conversation about where that capital should actually go, not a generic savings-account pitch. If a property sale under the new exclusion has left you with proceeds worth putting to real work, that's exactly the conversation we have.
Questions, answered
What is the capital gains tax exclusion on selling a house in 2026?
R3 million, for any sale where the agreement became legally binding on or after 1 March 2026 — up from the previous R2 million. It's the date of the binding sale agreement that matters, not the date transfer registers. The exclusion applies to a primary residence only, once.
How much tax do I actually save under the new R3 million exclusion?
At the top effective capital gains rate of 18%, the extra R1 million of exclusion is worth up to R180,000 in saved tax, for sellers whose gain is large enough to use the full amount. Smaller gains save proportionally less.
Does the R3 million exclusion apply if my sale agreement was signed before 1 March 2026?
No. If the sale agreement became legally binding before 1 March 2026, the previous R2 million exclusion still applies, even if the transfer only registers later. It's the binding date of the agreement that decides it, not the transfer date.
What should I do with the proceeds once the tax bill is smaller?
The question changes from how much tax you owe to how the money should actually be put to work. For proceeds large enough to matter, the useful split is between what needs to stay liquid and accessible, and what can be deployed for real growth — the same decision that applies to any significant capital event.
