AQQ v Comptroller of Income Tax

Holding

Section 33 of the Income Tax Act is a general anti-avoidance rule that empowers the Comptroller to disregard or vary arrangements whose purpose or effect, directly or indirectly, is to alter the incidence of tax, subject to the statutory commercial-purpose exception; on the facts, the financing arrangement was a tax-avoidance scheme but the Comptroller's particular adjustment exceeded what section 33 permitted.

Facts

AQQ, part of a Malaysian-owned group, undertook a corporate restructuring funded by a complex financing arrangement involving notes and back-to-back funding. The arrangement generated substantial interest deductions in Singapore against intra-group dividend income, producing a tax credit refund under the imputation system.

Reasoning

The Court of Appeal set out a three-step framework for section 33: (1) identify whether the arrangement falls within section 33(1); (2) consider whether the section 33(3)(b) commercial-purpose exception applies; (3) determine whether the Comptroller's adjustment is authorised by section 33(1). The Court found stages (1) and (2) against the taxpayer but held that the Comptroller's reassessment, in the manner formulated, was not authorised by the statute.
