- GST applies to supplies of NZUs by registered persons
- NZUs are considered services for GST purposes
- Most NZU supplies are zero-rated under specific sections of the GSTA
- Zero-rated supplies include transfers and surrenders of NZUs, certain Crown services, and similar units related to greenhouse gas emissions
- Zero rating means supplies are subject to GST at 0 percent
- Deregistering from GST while holding NZUs results in a zero-rated supply at deregistration with no GST consequences
