Estate Duty, Minor Children & The Guardian's Fund

Last Updated for the 2026/2027 Tax Year

Key Takeaways for Parents

Quick Links

Parents naturally want to ensure their children are financially secure if the unthinkable happens. However, leaving assets to minors (children under the age of 18) in South Africa involves strict legal rules that, if ignored, can result in your children's inheritance being locked away in a bureaucratic government fund.

Do Children Get an Estate Duty Exemption?

A common misconception is that leaving assets to your children is tax-free. This is incorrect.

While the Estate Duty Act allows you to leave unlimited assets to a surviving spouse tax-free (the Section 4q exemption), there is no such exemption for children. Any property, cash, or investments bequeathed to your children form part of your dutiable estate. The estate will only benefit from your standard R3.5 million (Section 4A) primary abatement.

The Danger of the Guardian's Fund

Under South African law, a minor child lacks "contractual capacity." They cannot sign legal documents, own property unassisted, or manage large sums of cash.

If you leave cash or the proceeds of a life insurance policy directly to a minor child without creating a trust, Section 43 of the Administration of Estates Act compels the Executor to deposit that money into the Guardian's Fund.

Scenario: Leaving a R5m Estate to a 10-Year-Old

The Situation: Mark is a single father. He passes away and leaves his entire R5,000,000 cash estate directly to his 10-year-old son, without setting up a trust in his will.

Step 1: The Estate Duty Calculation

Because the money goes to a child, not a spouse, it is fully taxable above the R3.5m threshold.

R5,000,000 (Estate) - R3,500,000 (Abatement) = R1,500,000 Dutiable.
Estate Duty = 20% of R1.5m = R300,000.

Step 2: The Aftermath

After paying the R300,000 tax and the Executor's fees, there is roughly R4.5 million left for the son.

Because the son is 10 years old, the Executor is legally forbidden from giving the money to him (or even to his legal guardian). The Executor must deposit the entire R4.5 million into the government's Guardian's Fund. The son's guardian will now have to petition the Master of the High Court every time the child needs new school clothes.

The Solution: Testamentary Trusts

You can easily bypass the Guardian's Fund by setting up a Testamentary Trust in your will.

Instead of leaving the assets directly to your minor children, your will stipulates that the assets are bequeathed to a Trust. Upon your death, the Trust is automatically created. You nominate trusted family members or professionals as the Trustees.

Pro Tip: Trust Advantages
A Testamentary Trust ensures that your chosen Trustees (not a government official) control the purse strings. They can immediately release funds for your child's education and well-being. Furthermore, you can stipulate that the Trust only pays out the final capital when the child reaches a more mature age, such as 25, rather than the legal age of 18.
