You can record income and expenses in the ATO app.

The ATO app is a simple and easy way you can access and manage your tax on the go. The ATO app is free to download and use. You can download it from Google Play or the Apple App Store. 

Through the app you can enter your ride-sourcing income and record how much GST is included. The app lets you take photos of invoices and receipts, and indicate (apportion) any private use.

You can also export that data to a spreadsheet, to help you calculate your GST obligations and complete your tax return.
