All information stated by evee in this article is general advice provided by the ATO and we will do our best to keep it up to date, however it is your responsibility to ensure you are following the current guidelines. If you have any questions specific to your situation, please seek the professional advice of an accountant.
The Australian Taxation Office (ATO) has an important article about how peer-to-peer car sharing works, which we recommend you read here. Income earned from renting out your car on the evee platform must be declared in your tax return. You can claim expenses for income tax purposes if they are directly related to the sharing of your car (e.g. membership fees, availability fees, and car expenses) and if you keep records such as receipts to back up your claims.
If you wish to register your car sharing activities under a business, please consult with your accountant first. As with income tax, there’s no one-size-fits-all solution and your accountant will be able to provide professional advice for your individual situation. In some cases, GST may be applicable and the ATO has an article about ‘How GST applies when sharing assets’ if you need more information.
