Hello


I was hoping someone could please help with a few questions:


  1. Is it possible to buy a car (for example in April 2026) and use it solely for personal use (for approximately 7 months), but then start a sole trading business (eg November 2026) and use the car for the business (in a ratio of approx 80% business: 20% personal) and claim a tax deduction on the car for the 2026-2027 financial year?
  2. If so and using the 'cents per km method' ... if I used the car for at least 5000 kms from November to June, could I claim the full 5000kms at 88c rate?
  3. If using the 'logbook method', would I have to work out the amount of days the car was used and then divide that by the total costs ie approx 240 instead of 365 days?
  4. Would I use the purchase price (April 2026) or the book value (November 2026) as the purchase price when working out the 'logbook method'?
  5. Would the purchase price even be a factor if using the 'cents per km method'?

Thanks heaps and all the best

Yes. A sole trader is an individual operating a business. Expenses on a car you own if you use for business purposes can be claimed,

Q2. Yes. Although what the cents/km rate will be in 2026-2027 is unknown.

Use a motor vehicle worksheet. Some expenses will need to be apportioned if incurred before car used for business but expense is for full year - registration and insurance for example. Apportion before adding to worksheet. Other expenses are those incurred after the business use has started - fuel, services, repairs, depreciation, etc. Add full expense to worksheet

Use purchase price as purchase price when calculating depreciation. Apportion depreciation to period car first used for business before adding to worksheet. Use the ATO tool to calculate depreciation.

Depreciation and capital allowances tool | Australian Taxation Office

Once all expenses are listed on worksheet multiply by logbook percentage to obtain claimable deduction.

Under cents/km you only need to keep a record of km travelled. Should keep all records of car expenses and establish a logbook so you can choose which is the best method to claim car expenses for the year.

Sorry Taxduck … one more scenario if that’s okay …


If I purchased other assets (to test them) before opening the business, but then used them in the business, could I also claim them as business assets or expenses?


For example, using the same time frame as the car purchase, I would be looking at buying a sample of garden beds, various soil components and seedlings to see which system worked the best before opening the business. After opening the business, I would still use the systems or offer them for sale.


Could I deduct these assets (or expenses) once I open my Sole Trader business, even if they were bought 6 months prior to businesses commencement and in a different Financial Year?


Thanks again :)
