GST credits based on business use percentage

You can only claim a GST credit to the extent that the purchases relate to your enterprise. Therefore you will need to work out the extent to which each expense was incurred for a business purpose, as opposed to personal use. Generally this is worked out by determining the extent to which an expense was used for a business purpose on a scale of 0-100.

Don’t worry about the tricky calculations of GST credits, our form will handle that. Just input the total amount spent (incl. GST) on each expense item for a period, and then assign a business use percentage next to it. You’ll notice our live GST calculator will change accordingly.

For car expenses, you will need to use a Logbook to more accurately determine this business use as a percentage.

Business use percentage examples:

Example 1 - let’s say you own a car which you use in the ride-sharing economy and also as a personal car. You use the car to travel 3,500 km for your ride-sharing activity out of a total of 5,000 kms in a quarter. On this basis, you use your car 70% for your ride-sharing enterprise and therefore could claim 70% of fuel costs relating to this car for the period.

Generally you will use the same business use percentage for fuel, car insurance, maintenance and cleaning expenses on your Airtax BAS form - as they all relate to the running of your car.

Example 2 - you’re a rideshare driver, and you have a phone internet bill of $99 for 3 months. You use your phone 60% of the time for the purposes of rideshare driving, and 40% for a personal use. Therefore the business use percentage for this phone internet bill will be 60%.
