Filing your GST return

Once you're registered for GST you need to file regular GST returns. Find out more about completing and submitting your GST returns, making GST payments and getting refunds.

Filing your GST return

You need to file a GST return at the end of every taxable period. You can do this:

If you're GST-registered and have a myIR account, you won't have paper returns mailed to you. We'll send you an email to let you know when your GST return is due.

You can't get an extension of time to file a GST return, so it's important to know when your GST returns are due.

Getting someone else to file your GST return

You can nominate someone else to file your GST return in myIR.

What a taxable period is

There are options to file your GST returns monthly, two monthly or six-monthly. The period you choose is known as your taxable period or filing frequency.

Completing your GST return

Our Working out your GST page explains what you need and how to complete your GST return. When you file your GST return in myIR or through accounting software many of your calculations are done for you.

If you've:

  • Paid out more GST than you've collected, you receive a GST refund.
  • Collected more GST then you paid, you need to pay the balance to us by the due date.

Filing through accounting sofware

You can file your GST return directly to us through accounting software. The benefits of filing through accounting software include:

  • your GST return data is already pre-populated from your sales and purchase figures
  • you don't need to transfer your figures into your myIR or paper GST return
  • you receive a real-time confirmation receipt of submission.
Note

If you have selected the ratio option to calculate your provisional tax, you can still prepare your GST return, but you can't submit through accounting software. You'll need to file your combined GST and provisional tax return (GST103) in myIR.

If you already use accounting software to manage your accounts, talk to your software provider about whether this filing feature is available as part of their software package.

Making a GST payment or getting a refund

GST payments

You make GST payments to us when you file your GST return by:

  • internet banking

  • direct debit.

Avoid interest and penalties by paying GST by the due date

GST refunds

GST refunds will be direct credited within 10 working days of us receiving your return unless we notify you we intend to:

  • withhold payment, or
  • investigate the return.
