New Zealand GST returns

Once registered for Goods and Services Tax (GST) in New Zealand, businesses must declare all taxable transactions and remit any GST due to the Inland Revenue Department (IRD).

New Zealand GST returns are typically filed on one of the following bases, depending on annual turnover and business preference:

• Six-monthly: For businesses with turnover under NZD 500,000
• Two-monthly: Standard filing frequency for most businesses
• Monthly: Required for businesses with turnover over NZD 24 million or those who elect monthly filing

The filing frequency is selected at registration and can be changed later with IRD approval.

GST returns must generally be submitted by the 28th day of the month following the end of the taxable period.

For example, a two-month return for January–February is due by 28 March.

If the due date falls on a weekend or public holiday, the deadline is moved to the next working day.

GST-registered businesses must maintain adequate GST records, including:

• Sales and purchase invoices
• Import and export documentation
• Accounting records supporting GST entries
• Electronic or paper records in English or Māori

Records must be retained for seven years and must be accessible for inspection by Inland Revenue upon request. 

GST payments are due on the same date that the GST return is due — typically the 28th of the month following the end of the return period.

Late payments may attract interest and late payment penalties under New Zealand tax law. 

Input GST may be reclaimed on goods and services used for taxable business activities, including:

• Goods purchased for resale
• Business equipment and capital assets
• Professional services and overheads
• Import GST paid on goods brought into New Zealand
• Pro rata deductions for mixed-use items (e.g., telecoms, vehicles)
   

GST is not deductible on private or exempt expenses, and fringe benefit tax (FBT) rules may apply for certain items.

All GST returns must be submitted electronically via Inland Revenue’s myIR portal.

GST payments can be made via online banking, direct debit, or other methods provided by IRD.

Penalties may apply for GST noncompliance, including:

• Late filing penalties for overdue returns
• Interest on late GST payments
• Shortfall penalties for underreporting or incorrect returns
• Additional penalties for fraud or gross carelessness
