If a passenger requests a tax invoice (not just an invoice) for a fare over $82.50 (including GST), you must provide one within 28 days of their request.
The platform might do this on your behalf if they have your GST registration details. However, if they don't, you need to provide a tax invoice that includes your ABN (such as using a tax invoice book with your ABN on it).
The tax invoice must contain certain information including your ABN. If the platform will issue tax invoices on your behalf, you should advise them of your GST registration details.
Any fares under $82.50 (including GST) do not require a tax invoice so you can just issue an invoice.
