As we covered in our previous guide, [How to Complete Your Centrelink Profit and Loss Form and Avoid a Debt](https://www.allsorted.au/centrelink-profit-and-loss?hsLang=en), honest maths mistakes and unverified estimations are the leading causes of Centrelink debts. But there is one specific area that trips up almost everyone: **Goods and S[![Centrelink Profit and Loss Statement and GST](https://knowledge-base.allsorted.au/hs-fs/hubfs/Centrelink%20form%20and%20GST.jpg?width=305&height=758&name=Centrelink%20form%20and%20GST.jpg)](https://knowledge-base.allsorted.au/hubfs/Centrelink%20form%20and%20GST.jpg?hsLang=en)ervices Tax (GST)**. Should you include GST in your income and expenses when reporting to Services Australia? The answer is not a simple yes or no—it depends entirely on your business's ATO registration status. When to EXCLUDE GST **If your business is registered for GST**, you must **exclude** GST from both your reported income and your allowable business expenses on the Centrelink Profit and Loss form. - **Income:** The GST you collect from customers is not your money; it is collected on behalf of the ATO. Centrelink does not assess this 10% as part of your personal income. - **Expenses:** Because you claim GST credits back from the ATO for your business purchases on your BAS, Centrelink does not allow you to double-dip and claim the GST portion as a business expense against your income support. When to INCLUDE GST **If your business is NOT registered for GST**, you must **include** GST in your reported figures. - **Expenses:** When you buy supplies and pay GST at the register, you cannot claim that GST back from the ATO. Therefore, the total out-of-pocket cost (including the GST) is considered your true allowable business expense by Centrelink. - **Income:** You should not be charging GST to your customers in the first place, so your gross income reported is exactly the total amount they paid you. The Debt Trap Getting this classification wrong has immediate consequences for your payment rate: 1. **Reporting GST in expenses when registered:** You will artificially inflate your deductions. Centrelink will calculate your net income as lower than it actually is, overpay your fortnightly rate, and potentially issue a debt notice when they eventually data-match your income tax return. 2. **Reporting GST in income when registered:** Your net profit will look artificially high, and your income support payments will be unfairly reduced.
