Key Takeaways
- The GST turnover threshold is **$75,000** for most businesses and **$150,000** for non-profit organizations.

- Registration is a simple process that can be done online via the ATO or through a registered agent.
In 2026, many Australian sole traders and small business owners are confused by when and how to register for Goods and Services Tax (GST). With the ATO’s increasing use of bank-feed data matching, missing the registration threshold can lead to severe back-taxes and penalties. Here is the ultimate step-by-step guide to GST registration.
Who Must Register?
You MUST register for GST if:
- Your business has a current or projected GST turnover of **$75,000 or more.**
- You provide taxi or limousine travel (including ridesharing like Uber), regardless of your turnover.
- You want to claim fuel tax credits for your business.
- You are a non-profit organization with a GST turnover of **$150,000 or more.**
Step-by-Step Registration Process
- Get an ABN: You cannot register for GST without an Australian Business Number. If you don't have one, apply for an ABN first.
- Choose Your Accounting Method: You can choose between **Cash** (simplest for small biz) or **Accruals** accounting for your GST reporting.
- Select Your Reporting Frequency: Most small businesses choose to lodge their Business Activity Statement (BAS) quarterly.
- Apply Online: You can register via the **ATO's Business Portal** (using myGovID) or through your registered tax agent (like PrepMyBook).
- Once Registered: You must start including GST (10%) in your prices and issuing **Tax Invoices.**
💡 Tip: You can also choose to **voluntarily register** for GST even if your turnover is below $75,000. This allows you to claim back the GST you pay on your business expenses, but you'll have to lodge quarterly BAS.
