Are you wondering if you can deduct car loan interest on your taxes? With the myriad of expenses Australians face, finding ways to save on taxes is a common goal. As the cost of living continues to rise, understanding where you can legitimately reduce your tax burden is crucial. This is particularly pertinent when dealing with car loans, which are a significant financial commitment. Let's explore whether your car loan interest can offer you some tax relief.
Understanding Car Loan Interest and Tax Deductions
In Australia, the rules surrounding tax deductions for car loan interest can be complex. Generally, the Australian Taxation Office (ATO) allows deductions on car expenses if the vehicle is used for business purposes. The key consideration is whether the car is used to generate income. If so, a portion of the car loan interest might be deductible.
It’s important to distinguish between personal and business use. If the vehicle is used solely for personal purposes, such as commuting to and from work, the interest on the car loan is not deductible. However, if you're self-employed or use your vehicle for work-related tasks, you might qualify for deductions.
Current Market Information and Eligibility
As of 2026, car loan interest rates in Australia generally range from 6.49% to 12% depending on your credit score, the lender, and the type of vehicle. With Esteb and Co, we have access to 83+ lenders, providing you with competitive options tailored to your needs.
To be eligible for a car loan interest deduction, you must keep detailed records of your car's business use. This includes logbooks, receipts, and a clear demarcation of personal versus business use. The ATO requires a logbook to be maintained for a minimum of 12 continuous weeks to substantiate claims.
| Lender | Interest Rate Range | Eligibility Requirements |
|---|---|---|
| Lender A | 6.49% - 9.5% | Good credit score, steady income |
| Lender B | 7% - 10% | Self-employed, business use |
| Lender C | 8% - 12% | Flexible credit criteria, higher risk |
Steps to Deduct Car Loan Interest on Taxes
- Determine Business Use: Calculate the percentage of business use by maintaining a logbook for at least 12 weeks. This will help you identify the portion of car expenses that are deductible.
- Keep Detailed Records: Maintain records of all expenses related to the car, including fuel, maintenance, and interest payments. This will be crucial at tax time.
- Calculate Deductible Amount: Use the business use percentage to calculate the deductible portion of your car loan interest.
