In 1982, the respondent (Woulidge) established two trusts for his minor children, Laura and Douglas, who were income and capital beneficiaries. Shortly after creating the trusts, the respondent sold shares in four companies to the trusts. The trusts had no assets to purchase the shares, so the respondent financed the purchase by granting interest-free credit. Although the sale agreement entitled him to charge interest, he never did. From 1982 to 1987, the companies declared no dividends and the trusts received no income. In 1988, a restructuring occurred when CTP Ltd became interested in the business. A holding company was formed and each trust acquired 50% of shares in it. Each trust then sold half of its shareholding to CTP for R1,642,500, enabling the trusts to pay for the shares and generate income. SARS issued revised assessments for 1989, 1990, and 1991, taxing this income in the respondent's hands under section 7(3) of the Income Tax Act 58 of 1962. The respondent objected, and the matter proceeded through the Special Court and Full Court before reaching the Supreme Court of Appeal.
The appeal succeeded only to the extent that the in duplum rule did not apply. The order of the Cape High Court was set aside and replaced with an order directing the Commissioner to revise the assessments for the 1990 and 1991 tax years on the basis that the in duplum rule does not apply. No order was made as to costs in either the High Court or the Supreme Court of Appeal.
The binding legal principles established are: (1) Where a disposition under section 7(3) of the Income Tax Act contains both appreciable elements of gratuitousness and proper consideration, an apportionment may be made between the two elements, with the taxpayer bearing the burden of proof to show such apportionment is possible and how it should be effected. (2) The forbearance of interest on a loan or credit advanced represents a continuing donation for purposes of section 7(3), and the notional interest that should have been charged may constitute the extent of income deemed to be that of the parent. (3) The in duplum rule does not apply to limit notional interest calculations for tax purposes under section 7(3) where no actual interest was charged or accumulated. The rule operates in real commercial contexts to protect borrowers from lender exploitation; it cannot be triggered by the very element of gratuitousness that constitutes the disposition under the tax provision. (4) Where issues for determination in tax appeals have been delineated through constitutional information rights and pre-hearing correspondence, new substantive issues cannot be raised on appeal without denying the opposing party a fair opportunity to address them.
The Court observed that the passage in Joss v Secretary for Inland Revenue 1980(1) SA 674 (T) suggesting that apportionment is a logical necessity must be read in context of the facts of that particular case. In each case, the possibility and extent of apportionment under section 7(3) is a matter of fact, with the burden of proof resting on the taxpayer. Joss is merely a particular illustration of this general principle, not a statement of universal application. The Court also commented on the proper role of section 82 of the Income Tax Act regarding onus, noting that while it places the onus on the taxpayer, this only arises upon proper identification of the issues to be adjudicated - it cannot be used to circumvent procedural fairness requirements.
This case clarifies important principles regarding section 7(3) of the Income Tax Act, particularly: (1) the possibility of apportionment between gratuitous and non-gratuitous elements in transactions involving minor children's trusts; (2) the taxpayer's burden of proof in establishing such apportionment; (3) the treatment of interest-free loans as continuing donations under section 7(3); and (4) the inapplicability of the in duplum rule to notional interest calculations for tax purposes where the very absence of a commercial arrangement constitutes the gratuitous disposition. The judgment also reinforces procedural fairness principles regarding the raising of new issues on appeal, particularly in the context of tax litigation where constitutional rights to information apply.
