Your organisation must register for GST if your GST turnover is greater than $150,000 per year.
If your GST turnover is less than $150,000 your organisation can voluntarily register for GST. That decision will depend on the administrative needs of your organisation.
An organisation's GST turnover is its gross income, minus:
- GST included in sales,
- input taxed sales,
- sales not connected with an enterprise that your organisation carries on, and
- sales not connected with Australia.
Even if your organisation is not registered for GST, you should regularly check your GST turnover. If you expect that your turnover will reach $150,000 in the next year you may need to register for GST.
- see the GST registration page on the Australian Tax Office (ATO) website for more information about GST registration.
Hint: Seek advice from your accountant or tax agent if you're not sure.
