GST registration questions

What is the GST registration threshold in Australia?

The standard GST turnover threshold is $75,000 for a business or enterprise and $150,000 for a non-profit organisation. Some activities, including taxi and ride-sourcing services, have compulsory registration rules regardless of turnover.

How does the current GST turnover test work?

Current GST turnover generally covers the current month and the previous 11 months. Even when that total reaches the threshold, ATO guidance says registration may not be required if projected GST turnover is below the threshold.

How does the projected GST turnover test work?

Projected GST turnover generally covers the current month and the next 11 months. It should be based on a reasonable estimate of sales made or likely to be made during that period.

Should Etsy, Shopify, marketplace, and offline sales be combined?

Yes. GST turnover is based on the enterprise rather than one platform payout, so applicable sales across every channel and business activity should be combined. Use turnover before platform fees, not profit.

How soon do I need to register after meeting the threshold?

The ATO says you generally need to register within 21 days of becoming required to register. Confirm the effective date and any special circumstances with the ATO or a registered tax or BAS agent.
