CSUM 26/13 High Court holds s 19(3B) of the GST Act overrides s 19A(2); and whether registered person ceased to satisfy s 19A(1) requirements is determined at date of notification

09 Oct 2026 Case summaries / 2026

The plaintiff companies challenged the Commissioner’s decision not to direct them to account for GST on the invoice accounting basis under s 19A(2) of the Goods and Services Tax Act 1985 (GSTA).

The liquidator said he was required, under s 53(1)(cb) of the GSTA, to notify the Commissioner that the plaintiff companies had ceased to satisfy the requirements for payments basis and the Commissioner must therefore direct the companies to account for GST on an invoice basis.

The High Court held that s 19(3B) of the GSTA overrides or precludes the Commissioner frombeing required to give a direction under s 19A(2) and that the Commissioner must be satisfied at the time of notification that a registered person has ceased to satisfy the conditions in s 19A(1).

CSUM 26/12 Taxpayer required to pay GST on insurance sum

09 Oct 2026 Case summaries / 2026

Mainzeal [MZ} received funds from an insurer [QBE] for damage caused by four of MZ’s directors. The CIR considered the payment was subject to GST under s 5(13) GSTA because it was paid in relation “to a loss incurred in the course or furtherance of [MZ’s] taxable activity”. MZ argued it was not because the payment was not received “under a contract of insurance”.

The High Court considered the legislative history of s 5(13) GSTA to conclude MZ did receive the payment in relation “to a loss incurred in the course or furtherance of [MZ’s] taxable activity” and that it was subject to GST.
