Delta Corporation Ltd v Zimbabwe Revenue Authority

In May 1996, the accounting firm Deloitte and Touche wrote to the Commissioner of Taxes (COT) enquiring whether shareholders who elect to receive shares instead of cash dividends receive "bonus shares" under the Income Tax Act. The COT responded in July 1996 stating that shares received in lieu of dividends constitute bonus shares and do not attract withholding tax. Delta Corporation, relying on this letter, did not pay withholding tax on scrip dividends issued after 1996. In November 2006, the Commissioner-General (COG) of the Zimbabwe Revenue Authority demanded that Delta deduct and account for withholding tax for the three years prior to that date on scrip dividends issued. Delta objected, arguing that the 1996 letter constituted a binding advance tax ruling. The COG disallowed the objection, maintaining that scrip dividends are dividends subject to withholding tax, not bonus shares. Delta appealed to the High Court.

• Whether the 1996 letter from the COT to Deloitte and Touche constituted a binding advance tax ruling
• Whether Delta Corporation could rely on a letter addressed to Deloitte and Touche when it was not privy to that communication
• Whether scrip dividends (shares received in lieu of cash dividends) constitute 'bonus shares' exempt from withholding tax under the 9th and 15th Schedules to the Income Tax Act
• Whether the Zimbabwe Revenue Authority could retrospectively assess withholding tax based on a corrected interpretation of the law
• Whether the doctrine of estoppel prevents the revenue authority from correcting a prior mistaken view of the law

The appeal was dismissed with costs. Delta Corporation was required to pay withholding tax on scrip dividends for the three years prior to November 2006.

The binding legal principles established are: (1) A letter from a tax authority does not constitute a binding advance tax ruling unless it complies with all the statutory requirements prescribed in the relevant revenue legislation; (2) Scrip dividends (shares received in lieu of cash dividends after a dividend has been declared) are not the same as bonus shares - scrip dividends are still dividends subject to withholding tax because tax liability arises at the point of dividend declaration, before any shareholder election; (3) Bonus shares arise only when a company capitalizes undistributed reserve profits without first declaring a dividend - they are company-driven, whereas scrip dividends are shareholder-driven; (4) A revenue authority is entitled to retrospectively correct mistakes of law in the application of tax law, even where a taxpayer has relied to their detriment on the authority's prior mistaken view; (5) The doctrine of estoppel does not prevent a revenue authority from correcting an unlawful position and reverting to acting in accordance with the law - a revenue authority cannot be estopped from acting lawfully; (6) Tax law is strict liability law and ignorance or reliance on incorrect advice does not absolve a taxpayer from liability.

The court made several obiter observations: (1) The court noted that the appellant's continued insistence on its position despite clear statutory provisions was frivolous, which justified an order of costs; (2) The court emphasized that implicit in lawfulness is fairness - a revenue authority acting lawfully cannot simultaneously be acting unfairly; (3) The court observed that there is nothing preventing a shareholder from accepting part of a dividend in cash and part in shares, which further demonstrates the shareholder-driven nature of scrip dividends; (4) The court commented that the revenue authority is not entitled at law to give unlawful tax breaks that would prejudice the fiscus; (5) The court referenced the principle from United States jurisprudence that "Congress, not the Commissioner, prescribes tax law" - adapted to the local context, this means the legislature, not the revenue authority, determines what is taxable.

This case is significant in Zimbabwean tax law (with persuasive value in South African jurisprudence given similarities in tax systems) for establishing important principles regarding: (1) the strict statutory requirements for advance tax rulings and the consequences when informal opinions are given; (2) the distinction between scrip dividends and bonus shares for tax purposes; (3) the point at which tax liability arises on dividends (at declaration, not at the point of payment or shareholder election); (4) the authority's power to retrospectively correct erroneous interpretations of tax law; and (5) the inapplicability of estoppel to prevent a revenue authority from acting lawfully, even where taxpayers have relied on prior incorrect advice. The case reinforces the principle that tax law is strict liability law and that revenue authorities cannot be bound by unlawful concessions or mistakes.
