Capital Gains Tax at Death in South Africa: What the Estate Owes and How to Reduce It

Most South Africans understand that estate duty applies when someone dies with a substantial estate. Fewer realise that capital gains tax is also triggered on death — as a completely separate tax calculation, administered separately from estate duty, and handled differently from a living taxpayer's CGT obligations.

The two taxes interact but are distinct. Getting both wrong can significantly reduce the estate's value and leave heirs with less than expected.

Why Death Triggers Capital Gains Tax

South African tax law treats death as a deemed disposal of assets at market value. This means SARS treats the death as though the deceased sold all their assets on the day they died at fair market value — even though nothing was actually sold.

The difference between the base cost (what the deceased originally paid for each asset) and the market value at death constitutes a capital gain, and CGT applies to that gain at the inclusion rate applicable to the estate.

This deemed disposal applies to:

• Shares and securities portfolios
• Investment properties (not the primary residence, subject to limits described below)
• Business interests
• Cryptocurrency and digital assets
• Any other capital asset with a gain

The deemed disposal does not apply to assets that are excluded from CGT by law, or to assets where specific exemptions reduce the taxable gain to zero.

The R440,000 Death Exclusion

For the 2026/27 tax year, the specific "death exclusion" allows R440,000 of capital gains to be excluded from the CGT calculation. This is substantially higher than the annual exclusion available to living taxpayers (R40,000 per year).

This exclusion applies once, to the full value of gains across all assets at the date of death. After deducting the R440,000 exclusion, the remaining gain is included in the deceased's taxable income at the inclusion rate and taxed at the marginal tax rate that applies to the estate.

The Primary Residence Exclusion

The primary residence exclusion provides the most significant CGT protection at death. A gain of up to R3 million on the disposal of a primary residence is excluded from CGT entirely. For most South African families where the primary asset is the family home, this exclusion eliminates CGT on property gains up to R3 million.

The R3 million exclusion applies where:

• The property was the deceased's primary residence (where they actually lived, not an investment property)
• The property was owned partly or wholly by the deceased

If the gain exceeds R3 million (applicable to high-value properties in major metropolitan areas), only the gain above R3 million is subject to CGT after applying the death exclusion.

How CGT at Death Differs From Estate Duty

It is important to understand that CGT and estate duty are calculated separately:

Capital Gains Tax:

• Calculated based on the gain in value of assets since their acquisition
• Applied as a tax on the deceased's final income tax return
• The taxable portion is included in income and taxed at marginal rates through the deceased estate's income tax return (the estate is a separate taxpayer)
• Reduced by the R440,000 death exclusion and the primary residence exclusion

Estate Duty:

• Calculated on the net value of the estate (assets minus liabilities)
• Applied at 20% on amounts above the R3.5 million Section 4A abatement
• Entirely separate calculation from CGT
• Has its own set of deductions, including the spousal exemption under Section 4(q)

Both taxes can apply to the same estate. The executor must calculate both, file the relevant returns, and pay both before the estate can be finally distributed.

What the Executor Must File

The executor has several tax obligations after a death:

1. Final pre-death income tax return: A tax return covering the period from 1 March of the relevant tax year up to the date of death. This is filed on behalf of the deceased person and includes all income earned up to the date of death. The CGT calculations are incorporated here.

2. Estate income tax return: A separate return for the deceased estate as a taxpayer in its own right. Any income earned by the estate after the date of death — rental income on an estate property, interest on bank accounts, dividends from shares — must be reported on this estate income return for each tax year until the estate is finally wound up.

3. Estate duty return (REV267): The estate duty calculation submitted to SARS, showing the gross value of the estate, deductions (including the Section 4A abatement and Section 4(q) spousal exemption), and the resulting estate duty payable.

4. SARS tax clearance: Before the executor can distribute the estate to heirs, they must obtain a formal tax clearance from SARS confirming all tax obligations have been settled. No distribution is permitted without this clearance.

Practical Implications for Surviving Families

If the primary asset is the family home: In most cases, the primary residence exclusion of R3 million eliminates CGT on the family home. The estate's main tax burden will likely be estate duty (if the estate exceeds R3.5 million) rather than CGT.

If there is a significant investment portfolio: A large portfolio with significant unrealised gains will trigger CGT on death. The executor should work with a tax professional to calculate the liability before making any distributions, as the CGT liability reduces the estate's distributable value.

For investment properties: CGT applies to gains on investment properties (as opposed to the primary residence). These can produce significant CGT liabilities in areas where property values have appreciated substantially.

The spousal rollover: Assets inherited directly by a surviving spouse typically transfer at cost base rather than market value — meaning CGT is deferred until the surviving spouse eventually sells or dies. This rollover reduces the immediate CGT burden on the estate and is one of the most valuable tax planning mechanisms in the South African system.
