Unicomer (St Vincent) Ltd v Appeal Commissioners: Privy Council remits insurance tax assessments but upholds hire purchase ruling

The Judicial Committee of the Privy Council has delivered a split decision in a significant Caribbean tax appeal, remitting two of three contested assessments for reconsideration whilst dismissing the third ground of appeal outright.

In Unicomer (St Vincent) Ltd v Appeal Commissioners and another [2026] UKPC 24, the Board considered whether the Revenue of Saint Vincent and the Grenadines had lawfully assessed the appellant, a "Courts"-branded furniture and appliance retailer, to additional corporation tax and withholding tax in respect of credit protection insurance ("CPI") premiums, and to income tax on the full sale value of hire purchase transactions at the point of contract rather than upon receipt of instalments.

The insurance premium assessments

The appellant had offered CPI to hire purchase customers through Massy United Insurance Limited ("United"), a Barbados-based insurer. United reinsured the risk with Canterbury Insurance Company Limited, a Bermuda-incorporated entity within the same Unicomer group, which ultimately received over 95% of the net premiums. When calculating its corporate income tax for 2007 to 2011, the appellant sought to deduct the CPI premiums of EC$4,450,000 as a legitimate business overhead. The Revenue disallowed the deduction under section 23 of the Income Tax Act, treating United as a mere conduit, and simultaneously levied withholding tax of EC$890,000 on the same sum under section 66.

The Revenue conceded before the Board that, given the High Court's unchallenged finding that United was not a sham or conduit, the assessments as framed were inconsistent with those findings and potentially excessive. Lady Simler, delivering the judgement of the Board, accepted that the Revenue was right to make that concession.

The appellant pressed for the assessments to be quashed entirely. The Board declined. Despite the rejection of the conduit case, it identified features of the evidence capable of engaging section 23 independently. Most significantly, the appellant's audited financial statements, prepared by KPMG, consistently recorded CPI premium payments as flowing directly to Canterbury rather than to United for a period spanning at least seven years. The appellant attributed this to an accounting error, but the High Court judge had found that explanation "wholly incredulous", a conclusion the Board found was plainly open to her. The appellant's own finance director had also admitted to the Revenue that United acted as Canterbury's local agent.

The Board further noted that United paid out only 12.2% of net premiums in claims, with the remaining 87.8% flowing to the related reinsurer, raising questions as to whether the arrangement was commercially normal absent the intra-group connection. These factors, taken together, were sufficient to keep open the possibility of a valid assessment under section 23. The matter was remitted to the Appeal Commissioners, rather than the High Court, on the basis that the Commissioners are the specialist body with appropriate statutory powers under sections 104 and 105 of the Income Tax Act.

The deferred hire purchase payments

The third issue concerned whether income from hire purchase sales accrued for tax purposes at the point the agreement was signed or only as instalments were received. The Revenue had assessed the appellant on the former basis, relying on section 9(1)(b) of the Income Tax Act, which provides that where a commercially recognised accounting system other than the cash basis is regularly followed, income accrues when credited in the taxpayer's books.

The appellant argued that prevailing commercial accounting standards, including the distinction between finance and operating leases under IFRS 16, should govern the analysis and required the Revenue to adduce expert evidence to establish its case.

The Board rejected both arguments. Section 9(1)(b) does not mandate the use of external accounting standards to determine the timing of accrual; it simply identifies the point at which income enters the books as the taxable moment. The appellant's own evidence, including affidavit evidence from its Regional Tax Manager and KPMG partner, confirmed that the full hire purchase price was credited to the books at inception. No distinction was drawn between the books of account and the audited financial statements. The Revenue was therefore plainly entitled to apply section 9(1)(b) without expert evidence.

The appeal on this issue was dismissed. The Board advised His Majesty that the appeal on issues one and two should be allowed only to the extent of remitting those assessments to the Appeal Commissioners, with the third issue dismissed outright.
