Left a House in South Africa? Estate Duty Still Reaches It

A lot of South Africans abroad keep one asset at home: a house, a flat, a piece of land. Often it is the family home, kept for sentimental reasons or rented out, and mentally filed under "dealt with later".

Here is the sentence from SARS that makes it a live question:

Estate Duty is levied on the worldwide property and deemed property of a natural person who is ordinarily resident in South Africa and on South African property of non-residents.

Leaving South Africa does not take South African property out of scope. Your worldwide estate stops being South Africa's concern when you stop being ordinarily resident. The house does not.

The numbers

Two figures, both from SARS.

An abatement of R3.5 million is allowed against the net value of the estate to determine the dutiable value.

The rates are 20% on the first R30 million of dutiable value, and 25% above R30 million.

Applied to a South African estate, before any deductions:

Read that table as arithmetic, not as your liability. It ignores every deduction. SARS says "various deductions under section 4 of the Estate Duty Act, 1955 are allowed to determine the net value of the estate" — and we have not enumerated them, so the table shows what the rates do to a number, not what your estate would actually owe.

What it does show is the shape. The abatement means a modest property may attract nothing. Above it, duty climbs as a share of the estate — 6% at R5 million, 13% at R10 million — because the abatement is a fixed amount being spread thinner.

The two questions we could not answer, and why that matters

This is the part to read if you are married, because these are the provisions most likely to change your answer, and we could not verify either.

The spousal position. South African estate duty law contains deductions under section 4, and the treatment of property accruing to a surviving spouse is among the most consequential of them. SARS's page confirms section 4 deductions exist but does not set them out, and we could not surface the spousal wording.

Whether an unused abatement transfers. There is a widely-discussed mechanism by which an abatement not used in the first death may benefit the survivor's estate. We could not confirm it from the source, so we are not describing how it works.

We are flagging both loudly rather than quietly leaving them out, because a page that presented the table above without mentioning them would mislead by omission. If you are married, those two questions may matter more to your estate than everything else on this page. Take them to SARS or a fiduciary practitioner.

What "South African property" means is its own question

The rule is that South African property of non-residents is dutiable. What counts as South African property is a legal question we are not answering.

Immovable property in South Africa is the obvious case and the one most readers are asking about. Beyond that — shares in South African companies, money in South African accounts, a policy written here, an interest in a South African trust — the analysis gets more involved and "deemed property" is a defined concept with its own rules.

If your South African connection is anything other than a house, that is a question for a practitioner rather than a table.

What else we have not covered

A deliberately long list, because on estates the gaps are the risk:

• Capital gains tax on death. A separate mechanism from estate duty and not sourced here. It can be significant on a long-held property.
• Executor's remuneration, and how it is calculated.
• Master's fees and the cost of administering the estate.
• Whether a foreign will covers your South African assets, and whether a separate South African will is advisable. This is one of the most common practical questions and it has a real answer we did not source.
• Any double tax agreement dealing with estates or inheritance between South Africa and your country of residence.
• The section 4 deductions in full, as above.

For any of it: SARS and a fiduciary or estate practitioner in South Africa. This page reports two published figures and one published scope rule; it is not estate planning advice, and estate duty rates and the abatement are set by legislation that changes.

Why the abatement behaves the way it does

The R3.5 million is a fixed amount, not a percentage, and that single fact explains the shape of the table above.

A fixed abatement is proportionally enormous on a small estate and proportionally trivial on a large one. At R5 million it shelters 70% of the estate. At R40 million it shelters under 9%. So the effective rate climbs steadily toward the headline rate as the estate grows, without any band being crossed:

Two things follow.

Nobody pays the headline rate. The 20% is a marginal rate on dutiable value, and because the abatement always comes off first, the share of the estate actually paid is always lower — approaching 20% but never reaching it until the second band starts pulling it upward again.

A fixed abatement erodes. It is a rand amount, and rand amounts lose purchasing power. South African property values and the general price level have both risen over the decade — the rand lost 37.8% of its purchasing power between 2015 and 2025 — while an abatement that does not move keeps the same nominal value. An estate that was under the threshold ten years ago may not be now, without anybody buying anything.

That is worth knowing precisely because it happens invisibly. There is no letter telling you your estate crossed a line.

Why this is a "before" problem, not an "after" problem

Estate duty is unusual among taxes in that the person it applies to is not around to deal with it, and the people who are dealing with it are doing so at the worst possible time.

Three consequences worth thinking about while it is abstract.

Duty is payable in rand, on a South African asset, from an estate that may have no South African cash. An estate consisting of one house and no bank balance has a liability and no obvious liquidity. What happens next is usually a forced sale, on somebody else's timetable.

Distance makes administration slower and more expensive. An estate with assets in two countries, heirs in a third, and an executor who has to be appointed in South Africa is a longer and costlier process than a domestic one.

The questions are cheap to ask now and expensive to ask later. Whether your foreign will covers the South African house, whether a separate South African will would help, what the spousal deductions actually do — every one of those has an answer available today, from a practitioner, for a fee that is trivial against the numbers in the table above.

If you have kept property in South Africa and never looked at this, that is the thing to fix — not by reading further, but by asking somebody qualified once.

How does this affect YOUR Money OS?

An asset you are not thinking about can carry a liability that lands on people who did not choose it, at a moment when they can least deal with it. That is worth one conversation.

FAQ

Does South African estate duty apply if I live abroad? Yes, to South African property. SARS levies estate duty on the worldwide property of a person ordinarily resident in South Africa, and on the South African property of non-residents. Emigrating does not remove a South African house from scope.

What is the estate duty rate in South Africa? 20% on the first R30 million of dutiable value and 25% on dutiable value above R30 million.

What is the estate duty abatement? R3.5 million, allowed against the net value of the estate to determine the dutiable value.

How much estate duty on a R6 million property? Before any section 4 deductions, R6 million less the R3.5 million abatement leaves R2.5 million dutiable, and 20% of that is R500,000. That is arithmetic on the published rates, not a calculation of any real estate's liability.

Is there a spousal exemption from South African estate duty? Section 4 deductions exist and the spousal position is among the most significant of them, but we could not verify the wording from SARS's published page — so we are not describing it. If you are married, ask a fiduciary practitioner, because it may matter more than anything else here.

Does my foreign will cover my South African house? That is a real question with a real answer and we did not source it. It is one of the most common practical issues for South Africans abroad and worth asking a practitioner directly.

Is capital gains tax also payable on death? Capital gains tax on death is a separate mechanism from estate duty. We have not covered it here, and on a long-held property it can be significant.
