Need to submit your GST return but unsure where to start? Understanding how to file an IRD GST return can help you manage your tax obligations, maintain accurate business records and avoid preventable filing mistakes. Whether you are a sole trader or operate a growing business, preparing the right information before you file can make the process more straightforward.
To file an IRD GST return in New Zealand, sign in to myIR, open your GST account, select the relevant return period, prepare your sales, income, purchases and expenses, enter the required figures, review the assessment and submit your return. You can also file through compatible accounting software or use a paper return where applicable. You must file for every taxable period, even if no GST is payable.
What Is an IRD GST Return?
A GST return reports the goods and services tax collected on your sales and the GST you may be entitled to claim on eligible business purchases and expenses. Inland Revenue uses the information to determine whether your business needs to pay GST or is entitled to a refund.
Businesses registered for GST must submit returns according to their assigned taxable periods. Filing a return is required even when there has been no business activity or no GST is due. This is commonly called a nil return.
How to File an IRD GST Return: Step-by-Step
Gather Your Business Records
Before you start filing your GST return, collect your sales invoices, purchase receipts, expense records, bank statements and any relevant GST adjustments. Make sure your figures cover the correct taxable period and agree with your accounting records.
Having organised records makes it easier to calculate your GST accurately and identify missing transactions.
Log In to Your myIR Account
Visit Inland Revenue’s official myIR portal and sign in securely. Select your GST account and open the returns or returns and transactions section.
Find the return for the taxable period you need to file. Check that you have selected the correct period before entering any figures.
Calculate Your GST
Work out your total sales and income, purchases and expenses, zero-rated supplies where applicable, and any credit or debit adjustments. Your GST accounting basis affects which transactions belong in the return.
If you use the invoice basis, some sales may need to be included before your customer pays. Under the payments basis, sales are generally accounted for when payment is received. Follow the rules for your registered accounting basis.
For guidance, refer to Inland Revenue’s GST calculation guidance.
Complete the GST Return in myIR
Select the appropriate filing option in myIR. Depending on the return, you may be able to enter GST amounts directly or provide total sales and purchases. Complete the requested fields, including any relevant adjustments.
Check whether you need to file a nil return if there were no transactions for the period. Do not leave a required return unfiled simply because your business was inactive.
Review Your GST Figures
Review the return carefully before submission. Check your sales, expenses, GST collected, eligible GST credits and adjustments against your accounting records. Make sure you have not included transactions in the wrong taxable period or claimed GST on ineligible expenses.
myIR calculates the resulting assessment based on the information entered. Review whether it shows GST payable, a refund or a nil result.
Submit Your Return and Arrange Payment
Submit the completed return and retain the filing confirmation. If GST is payable, arrange payment by the applicable due date. If your return results in a refund, check that Inland Revenue has your correct bank account details.
Filing and payment are separate responsibilities. Make sure both are completed where required.
When Is an IRD GST Return Due in NZ?
GST filing frequency depends on your registration and taxable period. The standard GST return and payment deadline is the 28th of the month following the end of the taxable period. There are exceptions for taxable periods ending on 31 March and 30 November.
- For a taxable period ending 31 March, the standard deadline is 7 May.
- For a taxable period ending 30 November, the standard deadline is 15 January of the following year.
- For most other taxable periods, the standard deadline is the 28th of the following month.
If a deadline falls on a weekend or public holiday, different next-working-day rules may apply. Always check your myIR account and Inland Revenue’s official tax calendar for your specific return and payment date.
What Happens If You File Your GST Return Late?
Missing a GST filing or payment deadline may result in late filing penalties, late payment penalties or interest, depending on the circumstances. Inland Revenue does not generally allow an extension of time to file a GST return, so it is important to prepare your records before the due date.
Common GST Filing Mistakes to Avoid
- Using the wrong taxable period: Check the return dates before entering transactions.
- Missing sales or expenses: Reconcile invoices, receipts and bank transactions.
- Claiming ineligible GST: Confirm that purchases qualify and that you hold the required records.
- Using the wrong accounting basis: Apply the invoice, payments or hybrid basis registered for your business.
- Forgetting a nil return: Submit every required return, even when no GST is payable.
- Submitting without checking: Review the assessment and retain confirmation after filing.
- Forgetting payment: Check whether an amount is payable and arrange payment by the relevant deadline.
