If you want someone else to file your GST return you can either:
- set up a nominated person
- grant others access to your myIR account.
Create web logon access for a myIR account
How to file your GST return
You can file your GST return either:
- in myIR
- through accounting software
- by filing a paper return - we'll send you this if you do not have a myIR account.
If you use the ratio option to calculate your provisional tax, you can only file in myIR or by paper.
Filing in myIR
You can file GST returns in your myIR account. The benefits of filing in myIR include:
- instant confirmation you have filed your return
- faster processing.
Filing in accounting software
You can file GST returns with us through some accounting software. The benefits of filing through accounting software include:
- your GST return is pre-populated so you do not need to copy figures into your myIR or paper return
- instant confirmation you have filed your return.
Your software provider can confirm if this filing feature is available as part of their software package.
If you receive a letter saying you have not filed your GST return
If you've filed a return, check it has been received in myIR. If it's showing as received, you do not need to do anything. If it is not showing, you will need to file a new return.
Calculating your GST
Before you can work out your GST total, you need to calculate your sales and income and your purchases and expenses.
