Estate duty is a tax that SARS levies on the value of your estate when you die. At 20% on dutiable amounts above R3.5 million — and 25% on amounts above R30 million — it represents a significant potential cost that, with proper planning, can be substantially reduced.
The key word is planning. Estate duty reduction strategies must be put in place during your lifetime. By the time you have passed away, the opportunities to act are gone. This guide explains the most effective, legally recognised strategies available to South African residents.
Understanding the Basics First
Before exploring reduction strategies, it helps to understand how estate duty is calculated.
Step 1: Determine the gross estate Add up the value of all assets owned by the deceased at date of death — property, investments, cash, retirement funds (if they fall into the estate), business interests, and any assets deemed to be part of the estate.
Step 2: Subtract allowable deductions Deduct liabilities (debts), funeral costs, and other allowable deductions under the Estate Duty Act 45 of 1955.
Step 3: Apply the abatement Every person is entitled to a R3.5 million abatement — the first R3.5 million of their dutiable estate is tax-free.
Step 4: Apply the spousal rollover Assets left to a surviving spouse are exempt from estate duty in the hands of the deceased spouse. The surviving spouse can also “inherit” any unused portion of the deceased spouse’s abatement, potentially allowing the combined estate to shelter R7 million from estate duty.
Step 5: Calculate the duty – 20% on the dutiable amount above the abatement, up to R30 million – 25% on the dutiable amount above R30 million.
For an estate of R10 million (single person, no special planning): – Dutiable estate: R10,000,000 − R3,500,000 = R6,500,000 – Estate duty: R6,500,000 × 20% = R1,300,000
That is R1.3 million that reduces what your heirs receive. The strategies below are designed to legally minimise that number.
Strategy 1: Leave Assets to Your Surviving Spouse
The most powerful estate duty exemption in South African law is the Section 4(q) deduction — a full deduction for any asset left to a surviving spouse. There is no limit on the amount.
This does not eliminate the estate duty problem — it defers it. The assets sheltered by the Section 4(q) deduction are included in the surviving spouse’s estate when they die. However, they also benefit from the surviving spouse’s own abatement, and if the surviving spouse’s estate grows more slowly (or is distributed to the next generation), the combined saving can be significant.
Practical implication: Your will should be structured to maximise the spousal bequest in a way that makes tax-efficient sense, while ensuring the surviving spouse has adequate resources. This requires balancing estate duty planning with the practical needs of the survivor.
Strategy 2: Maximise the Abatement Rollover for Married Couples
When the first spouse dies, their R3.5 million abatement is applied to their dutiable estate. If their entire estate is bequeathed to the surviving spouse (via Section 4(q)), the dutiable estate may be zero — meaning none of the first spouse’s abatement is “used up.”
The surviving spouse can then claim the unused abatement of the deceased spouse when they eventually die. This doubles the effective abatement to R7 million for the combined estate — a significant saving.
This rollover mechanism must be applied for when the surviving spouse’s estate is wound up. Ensure your executor is aware of it and your will is structured to support it.
Strategy 3: Donations During Your Lifetime
The Estate Duty Act and the Income Tax Act work together on this strategy. Reducing your estate before you die — by giving assets away — directly reduces the estate duty base.
Donations tax applies at 20% on the value of donations above R100,000 per year (per donor). So you pay 20% now, rather than up to 25% estate duty later. The R100,000 annual exemption allows you to give R100,000 per year, tax-free.
Over time, a disciplined donation programme — R100,000 per year, every year, for 20 years — removes R2 million from your estate without any donations tax.
Important: Donations to spouses and certain qualifying entities are also exempt from donations tax and can be used strategically.
Strategy 4: The Inter Vivos Trust
An inter vivos (living) trust is one of the most powerful — and most discussed — estate duty planning tools. The principle is simple: assets transferred to a trust no longer belong to you, so they do not form part of your estate when you die.
More powerfully, assets that appreciate in value after being transferred to the trust accumulate in the trust, not in your estate. For a high-growth asset (a business, a residential portfolio), the estate duty saving over 20 years can be enormous.
How it works in practice:
| 1. You sell assets to the trust (rather than donating, to avoid donations tax) at fair market value. |
| 2. The trust owes you the purchase price — recorded as a loan account. |
| 3. The loan account is an asset of your estate. (it reduces the estate duty saving initially) |
| 4. You reduce the loan account over time through donations (using the R100,000 annual exemption) or by charging below-market interest and allowing the trust to repay the loan from trust income. |
| 5. Eventually the loan is extinguished — and the assets (plus all their growth) sit entirely in the trust. |
NOTE: SARS scrutinises trusts carefully. A trust that is not genuinely independent, properly funded, and correctly administered can be disregarded for tax purposes. Use a reputable attorney and ensure the trust is maintained properly.
NOTE: A key point, at the outset, is to note that if you have a family trust, being an inter vivos trust, or want to register one, placing your primary residence in this trust could be a mistake.
Your primary residence benefits from a R3million primary residence capital gains tax exclusion in terms of the Income Tax Act, but only if held in your personal name (not the name of a trust, company or related entity). This benefit remains for your spouse if you pass away before them.
Furthermore, the spousal rollover relief on the death of the first spouse which is available under the Estate Duty Act, is lost in circumstances where your primary residence is not held under your personal name.
Strategy 5: Life Insurance Held Outside the Estate
Life insurance can play two roles in estate planning: providing liquidity to pay estate duty, or, if structured correctly, reducing estate duty by ensuring the proceeds are not part of the dutiable estate.
If a life insurance policy is ceded to a trust, or if the beneficiary is a person (not the estate), the proceeds are paid directly to the beneficiary or trust and do not form part of the dutiable estate.
Conversely, if the policy is payable to the estate (or if the estate is named as beneficiary), the proceeds swell the dutiable estate and attract estate duty.
Also important: A life insurance policy held outside the estate provides liquidity to the estate — the estate duty bill must be paid within one year of death. An estate with illiquid assets (property, a business) and a large estate duty liability can face forced sales if there is no cash available.
Strategy 6: Charitable Bequests
Under the Estate Duty Act, bequests to qualifying public benefit organisations (as defined) are deductible from the dutiable estate. If philanthropy is part of your values, directing a portion of your estate to a qualifying charity in your will reduces the dutiable estate — and therefore the estate duty payable.
Strategy 7: Section 4(q) on Accrual Claims
In a marriage with the accrual system, when the first spouse dies, the surviving spouse may have an accrual claim against the estate. This claim — the amount the trust owes the surviving spouse to equalise accruals — is a deduction from the dutiable estate before estate duty is calculated.
This does not require any active planning — it is a function of the matrimonial property regime. However, understanding how it interacts with your estate plan allows you to structure the rest of your planning accordingly.
What Does Not Work
It is worth noting strategies that are not legitimate:
- Understating asset values — SARS values assets independently. Incorrect valuations attract penalties and interest.
- Sham trusts — a trust that is not genuinely independent of the founder will be disregarded. The courts and SARS are alert to this.
Transferring assets only on your deathbed — SARS has anti-avoidance provisions and can deem certain pre-death transfers back into the estate.
Frequently Asked Questions
At what estate value should I start planning for estate duty?
If your estate (including the surrender value of life insurance, your share of any property, and investments) is likely to exceed R3.5 million — or R7 million for a married couple — estate duty planning is worth considering. For estates under these thresholds, there is no current liability, though you should still have a valid will.
Does estate duty apply to retirement funds?
Usually not — retirement fund death benefits distributed directly to dependants under Section 37C of the Pension Funds Act do not form part of the deceased estate and are therefore not subject to estate duty. If the fund pays into the estate, estate duty does apply.
Can I use multiple strategies together?
Yes, and the most effective estate plans typically combine several approaches: a will structured to maximise Section 4(q) relief, a trust holding appreciating assets, annual donations, and life insurance outside the estate.
Is estate duty planning only for the very wealthy?
Estate duty becomes a consideration for many ordinary South Africans who own a home in a major city — property values mean that more estates than expected breach the R3.5 million threshold. It is worth reviewing your position regardless of whether you consider yourself “wealthy.”
Plan Now While You Still Can
Estate duty is a problem you can plan your way around — but only if you start early enough. Executor Law advises clients across South Africa on structuring their estates to protect what they have built. Speak to a specialist before the opportunity to act is no longer available.
