How often do I need to file GST returns in New Zealand (monthly, two-monthly, or six-monthly)?
Once registered for GST, you must file returns at one of three frequencies: monthly, two-monthly, or six-monthly. The frequency depends on your business turnover and can be changed if your circumstances change.
Filing frequencies:
| Frequency | Turnover Requirement | Due Date |
|---|---|---|
| Monthly | Over NZ$24 million (compulsory) or voluntary | 28th of the following month |
| Two-monthly | Default for most businesses | 28th of the month after the period ends |
| Six-monthly | Under NZ$500,000 turnover (on application) | 28th of the month after the period ends |
Two-monthly filing is the standard default frequency for most businesses. The six two-month periods run: Jan-Feb, Mar-Apr, May-Jun, Jul-Aug, Sep-Oct, Nov-Dec.
Six-monthly filing is available if your annual turnover is under NZ$500,000. You must apply to IRD for approval. The two six-month periods are typically April to September and October to March.
Monthly filing is compulsory if your turnover exceeds NZ$24 million, but any GST-registered business can choose to file monthly.
Key points:
- If the due date falls on a weekend or public holiday, the deadline moves to the next working day
- Returns and payments can be filed online through your myIR account
- Late filing or payment may incur penalties and use-of-money interest
- You can request a change to your filing frequency through myIR if your business circumstances change
The payments basis allows you to account for GST when you actually receive or make payments, which can be helpful for cash flow management in small businesses.
