What is GST in plain English?
GST is a tax added to the price of most goods and services, including imports. Inland Revenue explains it is a tax for people who buy and sell goods and services, that you might need to register if you supply goods or services, and that GST is charged at a rate of fifteen percent (Inland Revenue, GST (goods and services tax), accessed 2026).
- Fifteen percent is the standard rate Inland Revenue publishes on its GST hub
- Applies across most domestic supplies unless a specific exemption or zero rate applies
- Imports remain within the GST story Inland Revenue outlines on the same hub page
- Registration is driven by taxable activity and turnover tests, not by picking a label on a template alone
Example
You sell furniture in Christchurch and show GST-inclusive prices on the shop floor. At month end you reconcile taxable sales in your ledger with the GST collected before you copy figures into myIR.
