Thank you for your post. GST-Free (or FRE) is generally used to record sales that are GST-free sales other than export sales, such as fresh food purchases, medical services and products, and educational courses.
No-Tax (or N-T) is generally used to record sales that carry no GST, such as depreciation and cash transfers.
However, we always recommend that you consult your accountant or the ATO regarding the best code to use to ensure you are meeting all your tax obligations in your specific situation.
