15EBCommissioner’s approval for changes in end dates of taxable periods
Despite section 15E(1), the Commissioner may give approval under subsection (2) for a change in end date of a registered person’s taxable period in order to reduce the compliance costs that would arise if the person’s taxable period was required to end on the last day of a month. For example, they may have accounting systems that are not aligned with the cycle of calendar months, or they may intend to become a member of a GST group or leave a group during a taxable period.
On application by the person, the Commissioner may approve a change in the end date of their taxable period to a day that is not the last day of a month if the Commissioner is satisfied that—
- the person has good commercial reasons for the change of end date; and
- making the change is consistent with the purpose set out in subsection (1).
The Commissioner may withdraw an approval of change of end date given under subsection (2) at any time if the Commissioner considers a requirement set out in subsection (2)(a) or (b) is not met.
Subsection (5) applies—
- to a registered person other than—
- a person whose taxable period is a 6-month period under section 15(1)(a):
- a non-resident supplier whose taxable period is a 3-month period under section 15(6); and
- a person whose taxable period is a 6-month period under section 15(1)(a):
- when the person—
- has an accounting cycle that consists of 13 periods in a 12-month period that are each 4 weeks, or approximately 4 weeks, in length; and
- in relation to the accounting cycle, has a change of end date approved under subsection (2).
- has an accounting cycle that consists of 13 periods in a 12-month period that are each 4 weeks, or approximately 4 weeks, in length; and
For the purposes of subsections (1) and (2), the Commissioner may prescribe a method that the person may use to determine an approved taxable period end date for their circumstances. The method must provide—
- a system of deciding the end dates for the person’s taxable periods; and
- a way to enable the person to determine the corresponding due dates for the person’s filing and payment obligations under this Act.
