The thesis examined the current system of the taxation of wealth in South Africa with an emphasis on the taxes that apply upon the death of the taxpayer. The focus of the research was on the problems associated with estate duty, namely the issue of double taxation; the alleged cumbersome administration of the tax and the limited revenue that it brings in; it’s questionable efficacy due to extensive estate planning on the part of taxpayers while they are still alive and its lack of uniformity with other wealth taxes. An interpretative research approach was followed which involved analysing documentary data. The conclusions that were reached were that estate duty as a wealth tax in South Africa has been rendered ineffective due to the inherent problems associated with its application, namely the fact that double taxation exists, not only in the context of capital gains tax, but also in that taxpayers resent being taxed upon death after having paid income tax during their lives. The perceived unfairness that is associated with estate duty has caused the creation of a secondary industry of estate planning, with the aim of minimising estate duty, which industry has resulted in the ineffectiveness of estate duty and its limited revenue. No evidence could be found regarding the Treasury’s assertion that estate duty is a cumbersome tax to administer. The final conclusion reached was that the current estate duty regime needs to be overhauled preferably by extending the current system of capital gains tax and abolishing estate duty, with due consideration being given to the consequences associated therewith.
