Supreme Court of the United Kingdom

Unicomer (St Vincent) Ltd v Appeal Commissioners and Another (St Vincent and the Grenadines)

The hearing centered on Unicomer (St Vincent) Ltd’s challenge to a tax assessment, focusing on the appropriate accounting methodology under section 91B and the treatment of IFRS 16 operating‑lease versus finance‑lease accounting. The counsel argued that the Commissioner had not met the evidential burden to justify the tax position, insisting that raw transactional data—not merely published financial statements—must be examined. Key arguments referenced landmark cases such as the Odian decision and Odon Theatres, where courts required factual accounting evidence to ascertain a taxpayer’s true profit. The speaker highlighted the ambiguity between accrued and deferred tax, noting that the Commissioner offered no expert testimony on the commercial accounting system used, and therefore could not justify applying a specific IFRS interpretation. Notable excerpts included the court’s phrasing that “the court must determine the correct principle of commercial accountancy” and the description of “deferred profits” in Unicomer’s internal reports. A 2015 tax computation sheet was presented, showing a split between current tax (installments paid) and deferred tax (future‑due amounts), underscoring the dispute over what constitutes taxable profit for the year. If the court accepts these arguments, the tax assessment may be revised, compelling revenue authorities to adopt more rigorous, fact‑based accounting analyses. The ruling would set a precedent for future Caribbean tax disputes involving IFRS compliance and the interpretation of section 91B, potentially affecting multinational retailers’ tax liabilities region‑wide.
