Estate Duty in South Africa: Rates, Exemptions, and How to Calculate What the Estate Owes

South Africa does not have an inheritance tax in the traditional sense — the state does not tax beneficiaries when they receive their inheritance. Instead, it taxes the estate itself before distribution. This mechanism is called estate duty, and it is governed by the Estate Duty Act of 1955. If you are the executor of an estate — or the surviving spouse trying to understand what the estate will owe before assets are distributed — this is what you need to know.

What Gets Taxed: The "Dutiable Estate"

Estate duty is not levied on the total market value of everything the deceased owned. It is levied on the dutiable estate, which is calculated as follows:

Total gross assets (everything the deceased owned at date of death, at market value) minus allowable deductions (funeral costs, debts owed by the deceased, bequests to public benefit organisations, and assets passing to a surviving spouse) equals the dutiable estate value

This distinction matters enormously in practice. A R5 million property owned jointly with a spouse, where 50% passes directly to the spouse, may produce a dutiable estate of R2.5 million — well below the exemption threshold.

The Section 4A Abatement: The R3.5 Million Exemption

The Estate Duty Act provides a Section 4A abatement of R3.5 million. The first R3.5 million of the dutiable estate is exempt from duty entirely.

For most middle-class South African estates — where the primary asset is a paid-off family home, a vehicle, and some retirement savings — this exemption means estate duty is either zero or a modest amount.

The Tax Rates

On the portion of the dutiable estate above R3.5 million:

• 20% on dutiable value from R3.5 million up to R30 million
• 25% on dutiable value exceeding R30 million

Practical example: Estate with a dutiable value of R5 million.

• First R3.5 million: exempt (zero duty)
• Remaining R1.5 million: taxed at 20% = R300,000 estate duty payable

Practical example for larger estate: Dutiable value of R35 million.

• First R3.5 million: exempt
• Next R26.5 million (from R3.5M to R30M): taxed at 20% = R5,300,000
• Remaining R5 million (above R30M): taxed at 25% = R1,250,000
• Total estate duty: R6,550,000

The Spousal Rollover: Potentially Doubling the Exemption

One of the most valuable estate planning mechanisms in South Africa is the spousal rollover provision. Assets bequeathed to a surviving spouse are:

1. Exempt from estate duty in the first spouse's estate (they count as an allowable deduction)
2. Transfer the unused portion of the deceased's R3.5 million abatement to the surviving spouse

If Spouse A dies and leaves everything to Spouse B, and Spouse A's dutiable estate (excluding assets going to the spouse) is zero, Spouse A's entire R3.5 million abatement rolls over to Spouse B. When Spouse B eventually dies, they have a potential abatement of R7 million — their own R3.5 million plus the rolled-over amount from Spouse A.

This mechanism allows a couple to shelter up to R7 million from estate duty through careful will drafting. It is one of the most powerful but least-understood aspects of South African estate planning.

How to Calculate Estate Duty: A Practical Approach

The executor — who acts as the Representative Taxpayer — must calculate estate duty as part of preparing the Liquidation and Distribution (L&D) account. Here is the basic framework:

Step 1: Value all assets at date of death. Immovable property requires a valuation by a sworn appraiser (typically R4,000 to R7,000). Listed shares are valued at the closing price on the date of death. Bank accounts use the balance at date of death.

Step 2: Add up all allowable deductions: the funeral account, all debts owed by the deceased as at date of death, and the value of all assets bequeathed to the surviving spouse (these are deducted in full).

Step 3: Subtract deductions from gross assets to get the dutiable estate value.

Step 4: Apply the Section 4A abatement of R3.5 million (adjusted for any rollover abatement from a predeceased spouse if applicable).

Step 5: Apply the 20%/25% rate structure to the remainder above R3.5 million.

Step 6: Check whether any deemed property applies — life insurance policies paid into the estate (rather than to a beneficiary directly) are included; retirement fund payouts (subject to Section 37C of the Pension Funds Act) are generally excluded.

Important Assets That Fall Outside the Estate Duty Calculation

Not all assets are included in the estate duty calculation. Retirement fund benefits — pension funds, provident funds, preservation funds — are excluded from the deceased estate under Section 37C of the Pension Funds Act. The fund's board of trustees distributes these benefits to dependants at their discretion, independently of the executor and the will.

Similarly, life insurance policies paid directly to a named beneficiary (rather than to the estate) are excluded. Life insurance paid to the estate itself, however, is included.

When Estate Duty Must Be Paid

The executor must pay estate duty to SARS when submitting the estate duty return. The estate duty return must be filed within one year of the date of death (or within three months of being appointed executor, if later). Interest accumulates on unpaid estate duty.

If the estate does not have sufficient liquid assets — for example, if the primary asset is a property and there is limited cash — the executor may need to sell estate assets to fund the duty payment. This is one of the reasons why well-structured life insurance policies, owned outside the estate, are a common estate planning tool for high-net-worth individuals.

SARS and the DEC Letter

After the executor has filed all tax returns, paid the estate duty, and settled any outstanding income tax for the years up to and including the date of death, SARS conducts a final compliance check and issues the Deceased Estate Compliance (DEC) letter. The Master of the High Court will not close the estate file without this letter.

In practice, delays in obtaining the DEC letter are one of the most common causes of an estate running past the 12-month mark. SARS processes can be slow, and any outstanding income tax returns — including those going back several years — must be filed and assessed before the DEC letter is issued.
