How trusts preserve generational wealth

The estate duty savings are compounded over several generations.

ARTICLES ON trusts are often aimed at settlors or donors to highlight the benefit of trusts and the role they play in estate planning at the ‘first-generation’ level.  In this article, the author aims to illustrate to second-generation beneficiaries the effect of the decisions their parents took on their behalf to establish a trust in which to grow their assets.

The scenario

Client X retired 10 years ago, withdrew the tax-free portion of his retirement fund, and added this to other funds he held.  He then placed the total amount on loan account into a family trust for the benefit of himself and his children.

The funds were invested on the JSE, the income from which was capitalised and used to repay Client X’s loan account.

Client X also made annual donations to the trust in the amount of the donations tax allowance.  The result was that when Client X passed away recently, there was no loan account due to him by the trust.

As beneficiaries of the trust, Client X’s children A and B are aware that the trust was established for ‘estate planning’ purposes, but would like to know what this means to them in real terms.

Spelling it out

The returns of the JSE All Share Index over the 10-year period 31 March 1998 to 31 March 2008 can be illustrated by the results below.

  • 10 year total return (expressed as a percentage increase on initial investment): +368%
  • 10 year annualised return (expressed as an annual percentage increase): +16.68% p.a.

The effect of estate duty

Estate duty, levied at 20% on any estate valued above R3.5 million*, is taxed on the net asset value (NAV) of a person at the time of their death.  For the example below, we assume that the individual’s primary residence and personal goods have a net asset value of R3.5 million, and that any investment portfolios held in the individual’s name are subject to estate duty.

  • 10 year total return (less estate duty): +274%
  • 10 year annualised return (less estate duty): +14.11% p.a.

Trust assets are not subject to estate duty

If we assume that an investment of R1 million was made on 31 March 1998 in the name of a trust, estate duty is not payable and the beneficiaries would enjoy a ‘saving’ of R936 000 as illustrated below:

  • Initial Investment on 31 March 1998: R1 000 000.
  • Value as at 31 March 2008: R4 680 000.
  • Estate Duty payable (if the assets had not been held in trust): R936 000.
  • Net value at 31 March 2008 had the assets been subject to estate duty: R3 744 000.

So much for the second generation.  But what about the third generation?  If, on the death of Client X, the trustees distribute the total assets of the trust to the individual beneficiaries A and B (R4 680 000), this amount plus any additional growth would once again be subject to estate duty of 20% on the death of either A or B.  In contrast, if these funds were retained in trust or distributed to trusts for the benefit of A and their family and B and their family, there would be a further saving of 20%.

Cumulative savings

The effect is compounded over several generations.  Assuming a continued growth rate of 368% per decade, an amount of R1 million placed in trust and invested in the stock market for a period of 30 years, representing three generations of beneficiaries, would result in a substantial saving of estate duty of around R16 million (20% of the portfolio total of approximately R81 million).
