Commentary on determination

All legislative references in this commentary are to the Income Tax Act 2007 unless otherwise stated.

This commentary does not form part of this Determination. It is intended to aid in the understanding and application of the Determination.

Section 91AAS of the Tax Administration Act 1994 provides the Commissioner the power to issue a determination declaring an event to be an emergency event for the purposes of s MB 13(2)(r)(i). In setting this determination, the Commissioner must set a period relating to the event for the purposes of s MB 13(2)(r)(ii).

Section MB 13(1)(b) includes in the family scheme income of a person (which is used in the calculation of a person's Working for Families Tax Credit entitlement) the value of payments paid to the person used to replace lost or diminished income or used to meet usual living expenses. Section MB 13(1)(c) excludes certain payments from being included in family scheme income if it is listed in s MB 13(2).

Section MB 13(2)(r)(i) excludes from family scheme income a payment made to relieve the adverse effects of an event declared an emergency event by the Commissioner. This declaration must be made by way of determination under s 91AAS of the Tax Administration Act 1994. The payment must also be made within the time-period set by the Commissioner in the determination.

This determination declares the severe weather event to be such an emergency event and sets a time-period for the purposes of s MB 13(2)(r)(ii) to apply to payments received for the period from 15 January 2026 to 31 July 2026.

Beginning on 15 January 2026, this severe weather event delivered extremely heavy rain, high winds, landslides and widespread flooding to the following regions and districts:

Northland and Tairāwhiti regions
Thames-Coromandel, Hauraki and Western Bay of Plenty districts

Because the Commissioner has made the required declaration that this severe weather event is an emergency event, a payment made between 15 January 2026 to 31 July 2026 (inclusive of both dates) to relieve the adverse effects of this severe weather event will not be included in a person's family scheme income.
