Do I need to register for GST?

NZ registration is compulsory once turnover passes $60,000 in any rolling 12-month period.

$
$0$60,000 threshold
Turnover is your total taxable sales — not profit. Wages and salary, GST-exempt supplies (like residential rent and most financial services), and one-off capital asset sales don't count.
Indicative only — not financial or tax advice. GST is 15% in New Zealand on most goods and services, but some supplies are zero-rated or exempt. The registration threshold check is a guide based on the $60,000 rolling-12-month test. For your own situation, check IRD (ird.govt.nz) or talk to a registered tax agent or accountant.
