Do you pay estate duty on money left to a spouse in South Africa?

No. Under Section 4(q) of the Estate Duty Act, any assets (including cash, property, and investments) left to a surviving spouse are 100% exempt from Estate Duty. There is no monetary limit to this exemption.

Who qualifies as a spouse for estate duty purposes?

The definition is broad and includes legally married spouses, civil union partners, customary marriages, religious marriages, and permanent life partners (both same-sex and heterosexual), provided you can prove the permanence of the relationship.

Does my spouse still have to pay executor fees if the inheritance is tax-free?

Yes. This is a massive trap. While SARS does not charge the 20% estate duty on spousal inheritances, the Executor is still legally entitled to charge up to 3.5% (plus VAT) on the gross value of those assets to administer the estate.

The Section 4(q) Spousal Exemption

Last Updated for the 2026/2027 Tax Year

Key Takeaways: Inheriting as a Spouse

Unlimited Exemption: Any assets left to your surviving spouse are 100% exempt from the 20% Estate Duty tax. There is no limit on the value.
Broad Definition: You do not need a formal marriage certificate. Permanent life partners also qualify for the deduction.
The Catch: "Tax-Free" does not mean "Fee-Free". Your surviving spouse may still face crippling Executor's Fees and liquidity shortfalls.

In South African tax law, the government does not want to penalize a surviving spouse when their partner dies. To protect families from being forced to sell their homes to pay tax, the Estate Duty Act includes the ultimate tax break: The Section 4(q) Deduction.

The Golden Rule of SA Estate Tax

Section 4(q) is very simple: Whatever you leave to your spouse is completely exempt from Estate Duty.

If you have an estate worth R50 Million and you leave 100% of it to your spouse, your dutiable estate is R0.00. SARS takes nothing. Furthermore, because you didn't use your R3.5 million basic abatement, it rolls over to your spouse, giving them a massive R7 million abatement when they eventually pass away.

Who Qualifies as a "Spouse"?

South African law recognizes that modern families look different. The Estate Duty Act has a very broad definition of a "spouse". To claim the Section 4(q) deduction, you must fall into one of these categories:

💍

Civil Marriages & Unions Marriages concluded under the Marriage Act or civil partnerships under the Civil Union Act.

🌍

Customary Marriages Marriages recognized in terms of the Recognition of Customary Marriages Act.

🕌

Religious Marriages Unions recognized as marriages under the tenets of any religion (e.g., Islamic or Hindu marriages).

🤝

Permanent Life Partners Same-sex or heterosexual couples living in a permanent relationship. (Note: You must provide an affidavit to the Master of the High Court proving the relationship was permanent and analogous to a marriage).

The Trap: Executor Fees Still Apply

This is the most dangerous misconception in estate planning: Husbands and wives assume that because they leave everything to each other, there will be zero costs when they die.

While SARS waves the 20% tax, the Executor of the Estate does not wave their fee. The Executor is legally entitled to charge up to 3.5% (plus 15% VAT, totaling 4.025%) on the Gross Value of the assets they administer, regardless of who inherits them.

Bonus: The CGT "Step-in-the-Shoes" Rule

The spousal exemption doesn't just apply to Estate Duty; it also applies to Capital Gains Tax (CGT).

Normally, death triggers a "deemed disposal," meaning SARS taxes the capital growth of your assets on the day you die. However, if an asset is left to a spouse, the Income Tax Act dictates that the CGT event is deferred. The surviving spouse "steps into the shoes" of the deceased. They inherit the asset at its original base cost, and the CGT will only be triggered when the surviving spouse eventually sells the asset or passes away.

Scenario: The "Tax-Free" R10m Estate

The Situation: David and Sarah are married. David owns a business and a house in his own name, totally valued at R10,000,000. David dies unexpectedly. In his will, he leaves 100% of his assets to Sarah. He has no life insurance.

Step 1: The Estate Duty Calculation

Gross Estate: R10,000,000
Section 4(q) Deduction (To Spouse): -R10,000,000
Dutiable Estate: R0.00
Estate Duty Payable: R0.00

Step 2: The Executor's Fee Calculation

The Executor must transfer the house and the business shares to Sarah. They charge their legal maximum fee on the Gross Estate.

4.025% (incl. VAT) of R10,000,000 = R402,500.

The Reality: Sarah pays zero tax to SARS, but she still has a massive cash shortfall. If she doesn't have R402,500 in her personal bank account to pay the Executor, the Executor will be forced to auction the family home to raise the cash.

Pro Tip: Solving the Spousal Shortfall
If you intend to leave your entire estate to your spouse, you must ensure there is enough liquid cash to cover the Executor's fees. The most efficient way to do this is to take out a small life insurance policy that pays out directly to your Estate to cover administration costs, or negotiate a reduced Executor's fee with your attorney *before* you finalize your Will.
