Hi Team,


I have a question about the scenario as below : Can I please confirm if my calculations are right.

IAWO is $20,000


Scenario :

full time uber driver- sole trader purchased a car in FY2025 under finance and it is 100% business use.


Can I confirm if these case will go to the cost base for preparing depreciation ?


New Car costs : $50k ( capital cost and will be depreciated over 8 years )

Floor Mats : $200 ( capital cost and will be depreciated over 8 years )

Stamp Duty : $1130 ( capital cost and will be depreciated over 8 years )

Registration : $250 ( current expense )

CTP : $375 ( current expense )

Plate Fee : $33 ( current expense )


Finance Company Costs :

Repayments includes :

Principal cost : $150

Interest charge : $65 ( will be claimed for FY )

Account Fee :$5 ( will be claimed for FY)


Loan processing Costs :

Loan Establishment Fee : $450 ( is this a borrowing cost ? claimed over 5 years ? )

Origination Fee : $1500 ( is this a borrowing cost ? claimed over 5 years ?)

Registration of security :$10 ( is this a borrowing cost ? claimed over 5 years ? )


Questions :

1) Can he choose to claim car under small business pool 15% first year , instead of diminishing method and prime cost method.


2) or Can he chooses not to claim any depreciation method at all but only choose to claim principal repayments paid to the finance company for the car during FY.


3) Loan processing costs : do we treat them as borrowing costs to claim them over 5 years ? or we can add them to the value of car to depreciate along the car, or we can can immediately claim these costs.


4) a different scenario : What if car is second hand car and purchased for $30,000 in FY2025 , car built is 2018. what is useful life of this car, or can we choose business pool 15% now and 30% later ?


5) sorry last question : What if new car loan is under husband and wife name, wife has better credit score. but car is 100% used by husband for 100% business use (sole trader). registration and insurance everything is under husband's name and he pays all the other bills. can he claim cost of the car, interest on loan , rego and insurance etc under his sole trading business.


Thank You and really appreciate for your time.

Hey @Vand489 - I can definitely point you in the right direction, but as @YEP said you’re better off seeing a registered tax agent when it comes to checking your figures and making sure you can use certain methods within your business.


To be eligible for the Instant Asset Write-Off (IAWO):

  • Aggregated turnover must be under $10 million.
  • Asset cost must be under $20,000 (excluding GST).
  • Asset must be used or installed ready for use in the same financial year.

Q1: If you're eligible to use the simplified depreciation, you can use the small business pool instead of the prime cost or diminishing value method.


Q2 & Q3: You cannot claim principal repayments as a tax deduction. Only interest on the loan and depreciation of the car are deductible.


Q4: Second-hand cars can be used in small business pool as well. This means you shouldn't need to apply an expected life to the asset to your second-hand car.


If you're not using the small business pool method, there are two ways you can use to work out the assets effective life:


Q5: If the car is jointly owned or in the spouse’s name but used 100% for business and the sole trader pays all expenses, you can still claim deductions if there’s a clear private arrangement and proper records are kept.


As you mentioned your business is Uber driving, have a read through the info on our website about ride-sourcing.

You need to sit down with a tax agent or accountant so they can work through all your questions with you to ensure you get the right advice.
