Goods and services tax is one of the first tax questions a growing business faces. The Australian Taxation Office (ATO) is clear that not every business needs to register, but penalties may apply if you fail to register when you are required to.
When you must register
According to the ATO, you must register for GST:
when your business has a GST turnover of $75,000 or more, which is the GST threshold
when you start a new business and expect turnover to reach the threshold in the first year
if you run a non-profit organisation with a GST turnover of $150,000 or more a year
if you provide taxi or limousine travel for passengers, including ride-sourcing, regardless of turnover.
GST turnover is gross income from all your businesses, minus GST. The ATO has a guide to working it out.
Timing
Once you are required to register, you need to do it within 21 days. You only register once, even if you run more than one business.
You need an ABN first
Before registering for GST, you need an Australian Business Number. You can get one when you register your business name or later.
Keep an eye on the threshold
If your business is growing, check your turnover regularly rather than once a year. That way you register on time instead of discovering the obligation after the fact. You can also cancel your registration if you are no longer required to be registered.
