Estate Duty in South Africa: A Plain-Language Guide for Families With Significant Assets
South Africa's estate duty rate is 20% on dutiable estates up to R30 million, and 25% above that. Combined with capital gains tax on deemed disposals at death, an estate that looks straightforward can lose 30–40% of its value. Here is how to manage it.

Estate duty is one of South Africa's most misunderstood taxes. Many families assume it applies only to the ultra-wealthy, or that a will alone is sufficient protection. Neither assumption is correct. Estate duty applies to any South African resident whose dutiable estate exceeds the R3.5 million abatement — a threshold that includes assets people do not typically think of as "wealth", including life insurance proceeds, retirement fund payouts (in certain circumstances), and primary residences.
How Estate Duty Is Calculated
Estate duty is levied on the dutiable amount of an estate. The starting point is the gross value of all property of the deceased — South African and foreign assets for residents — from which allowable deductions are subtracted. The primary deduction is the abatement of R3.5 million, which applies to every estate. If a surviving spouse inherits all assets, the unused portion of the abatement can be rolled to their estate (the so-called "portability" of the abatement), effectively doubling the threshold for couples to R7 million.
The rate structure: 20% on dutiable estates up to R30 million, and 25% on the portion above R30 million. This sounds manageable until you factor in capital gains tax (CGT) triggered at death.
The Double Hit: Estate Duty Plus Capital Gains Tax
At death, SARS deems every asset to have been disposed of at market value — triggering CGT on any accrued gain above the R300,000 death exclusion. The effective CGT rate for individuals is currently 18% on the gain (40% inclusion rate × maximum 45% marginal rate). This CGT liability is deductible from the estate for estate duty purposes, but the combined effect is still significant.
Consider a property purchased for R1.5 million that is now worth R6 million. The R4.5 million gain (less the R300,000 exclusion) produces a taxable gain of R4.2 million. At a 40% inclusion rate and 45% marginal rate, the CGT liability is approximately R756,000. That liability then reduces the dutiable estate for estate duty calculation — but the estate still faces both charges simultaneously. A family expecting to inherit a R10 million estate could face a combined tax bill exceeding R2 million, payable within 12 months of the date of death.
Structures That Legitimately Reduce Estate Duty
Retirement fund proceeds paid directly to a nominated beneficiary (not to the estate) are excluded from estate duty. This makes maximising retirement fund contributions one of the most efficient estate planning tools available to South Africans — the funds bypass estate duty entirely if correctly structured and nominated.
Life insurance proceeds are generally included in the estate for duty purposes, but policies owned by a trust or by the beneficiary directly are excluded. The structuring of life cover ownership is therefore an important estate planning decision.
Inter vivos trusts (set up during your lifetime) can remove asset growth from your personal estate. Assets sold to a trust at fair market value, with the purchase price left outstanding as a loan, freeze the estate duty exposure at the loan value — while future growth accumulates outside your personal estate. This technique has survived SARS scrutiny where implemented correctly, though it requires careful legal drafting and ongoing compliance.
Spousal bequests are exempt from estate duty. Assets left to a surviving spouse do not form part of the dutiable estate — but they do not escape estate duty permanently; they simply defer it to the surviving spouse's estate. Couples with significant assets need to plan both estates, not just the first to die.
Liquidity: The Practical Problem
Even where the structures are correct, estates frequently face a liquidity crisis. Assets like property and business interests cannot be sold quickly, but the executor needs cash to pay estate duty within 12 months. Life insurance planned specifically to cover the estate duty and executor's fees (typically 3.5% plus VAT of gross estate value) is the standard solution. Without it, the executor may be forced to sell assets below market value under time pressure.
Estate planning is not a once-off exercise. As your asset values grow, the structures that made sense at R5 million net worth may not be optimal at R15 million. A licensed financial adviser working with an estate attorney should review your estate plan every three to five years, or after any major asset acquisition or life event.
