Do I have to register

GST is a self-assessed tax. Businesses are required to continually assess the need to be registered for GST.

In most cases, registering for GST is compulsory when:

• the turnover of your business is more than $1 million for the past 12 months; or
• you are currently making sales and you can reasonably expect the turnover of your business to be more than $1 million for the next 12 months.

Otherwise, you can choose to be voluntarily registered for GST. Please refer to the following links for more details.
