Estate Duty on Private Business Shares

Key Takeaways for Business Owners

Quick Links

For many South African entrepreneurs, their most valuable asset is their business. However, unlike cash in the bank or listed shares on the JSE, shares in a private company present a unique and dangerous estate planning challenge.

The Valuation Trap: Navigating SARS Rules

When you pass away, the shares you own in a private company (or your interest in a Close Corporation) are considered "property" under the Estate Duty Act and must be included in your gross estate.

The trap is valuation. You cannot simply list your shares at their original par value (e.g., 100 shares at R1 each). SARS requires the Executor to determine the fair market value of the business at the exact date of your death.

๐Ÿ“Š
Independent Audit Required The Executor must appoint an independent auditor or accountant to perform a valuation. They will typically look at Net Asset Value (NAV), earnings multiples, or discounted cash flows.
๐Ÿ“‰
Deemed Disposal (CGT) Death triggers Capital Gains Tax. If you started the business with R1,000 and it is now valued at R10,000,000, your estate must pay CGT on the massive capital growth before the shares can be transferred to your heirs.

The Liquidity Crisis

Private business shares are notoriously illiquid. Consider a scenario where your business is independently valued at R20 million, and you own 50% (R10 million). Your estate now owes 20% Estate Duty and a massive CGT bill on that R10 million asset.

Where does the Executor get the cash? The business shares cannot easily be sold to a stranger. If there is no cash in your estate, the Executor may be forced to demand the surviving business partners buy the shares, or worse, force the liquidation of the company to pay SARS.

Surviving partner pays the estate R 10m cash. Taxes are easily settled, and your heirs inherit the remaining millions in liquid cash.

*Taxes estimated at 24.025% (20% Estate Duty + 3.5% Exec Fee + VAT). Excludes standard R3.5m abatement for simplicity.

The Solution: Buy-and-Sell Agreements

The standard way to protect both your family and your business partners is to execute a Buy-and-Sell Agreement, funded by life insurance.

Here is how it works:

  1. You and your partners sign an agreement stating that if one of you dies, the surviving partners must buy the deceased's shares, and the deceased's estate must sell them.
  2. To fund this, Partner A takes out a life insurance policy on Partner B, and Partner B takes out a policy on Partner A.
  3. When Partner A dies, the insurance pays out millions in cash directly to Partner B. Partner B uses that cash to buy the shares from Partner A's estate.

Scenario: The R20m Agency Rescue

The Situation: Sarah and John own a digital agency 50/50. The business is valued at R20 million. They have a Buy-and-Sell agreement funded by R10m life policies on each other. John passes away.

Step 1: The Cash Injection

The insurance company pays R10,000,000 in cash directly to Sarah (the surviving partner). Sarah immediately pays that R10m to John's Executor to buy his 50% shareholding.

Step 2: The Tax Exemption

Normally, life insurance is added to the estate as "deemed property". However, under the Section 3(3)(a) proviso of the Estate Duty Act, Buy-and-Sell policies are 100% exempt from Estate Duty.

John's estate is taxed on the R10m cash he received for the shares, but the actual insurance policy itself does not inflate his estate further.

The Verdict: A Perfect Transition.
Sarah now owns 100% of the business debt-free. John's family receives R10m in liquid cash, easily paying their Estate Duty and Executor fees while remaining financially secure.

Keyperson Insurance vs. Buy-and-Sell

Many business owners confuse these two policies, but they serve completely different purposes and have drastically different tax implications upon death.

Feature Buy-and-Sell Policy Keyperson Policy
The Purpose To buy out a deceased partner's shares. To inject cash into the business to replace lost revenue when a crucial employee dies.
Who owns the policy? The Business Partners (in their personal capacity). The Company (The Pty Ltd or CC).
Who gets the cash? The surviving partners. The Company's bank account.
Estate Duty Impact? 100% Exempt from Estate Duty. Increases the Value of the Shares. The cash payout increases the company's Net Asset Value, thereby increasing the Estate Duty the deceased owner must pay.

Warning: The Premium Payer Trap

To qualify for the Section 3(3)(a) estate duty exemption on a Buy-and-Sell life insurance policy, the Estate Duty Act is incredibly strict about one rule:

The Deceased Cannot Have Paid the Premiums!

A massive mistake business owners make is having the company pay the life insurance premiums to save on personal admin. If the company pays the premiums, SARS argues that the deceased (as a shareholder of the company) indirectly paid the premiums. This voids the exemption, and the entire multi-million Rand policy will be slapped with a 20% Estate Duty tax bill.

Always ensure partners pay the Buy-and-Sell premiums out of their personal, after-tax bank accounts.

Pro Tip: Regular Valuations A Buy-and-Sell agreement is useless if your business grows to R50m but your insurance policies are still stuck at R5m. You must review your business valuation and update your life cover annually.
