Top 10 NZ GST Registration Mistakes (and How to Avoid Them)
From compulsory $60k turnover thresholds to claiming second-hand goods and zero-rated exports, avoid costly IRD audits with this checklist.
Key Takeaways Summary
- ✓Monitor rolling 12-month turnover continually, not just at year-end.
- ✓Payments basis protects cashflow by paying GST only after receiving funds.
- ✓Tax invoices with IRD number and GST breakdown required for claims over $50.
Goods and Services Tax (GST) is one of the most strictly policed areas by Inland Revenue. Mistakes in registration timing or input tax credits can attract automatic shortfall penalties.
The Mandatory $60,000 Threshold
Businesses in New Zealand must register for GST when turnover exceeds $60,000 in any rolling 12-month period, or is expected to exceed $60,000 in the next 12 months.
Waiting until annual accounts are prepared months later is too late—registration must be backdated, leaving the business liable for 15% GST on historical income without having collected it from customers.
Invoice Basis vs Payments Basis
Most small businesses and property investors should opt for the Payments (Cash) basis to avoid paying GST on unpaid client invoices.
Ensure valid tax invoices are held for all business expense claims over $50 NZD. Bank statements alone are insufficient for IRD input tax verification.
