Car Loans Tax Deductible? Unlock Savings Fast (2026)

When it comes to managing your finances, understanding what expenses you can claim on your taxes is essential. One common question Australians have is whether car loans are tax deductible. With the right information, you can make informed decisions about your vehicle financing and potentially save money at tax time. Let's dive into the details of car loan tax deductibility in Australia and how to navigate this aspect of your financial planning.

Understanding Car Loan Tax Deductibility

Car loans themselves are not directly tax deductible in Australia. However, the interest you pay on a car loan can be deductible if the vehicle is used for business purposes. This means that if you use your vehicle for work-related activities, such as travelling between job sites or meeting with clients, you may be able to claim the interest as a deduction on your tax return.

It's important to note that only the portion of the interest related to the business use of the vehicle can be claimed. If your car is used for both personal and business purposes, you'll need to calculate the percentage of business use to determine the deductible amount.

Current Market Information and Options

As of 2026, car loan interest rates in Australia typically range from 6.49% to 12%, depending on factors such as your credit score, the loan term, and the lender. With Esteb and Co's access to a panel of 83+ lenders, you have the opportunity to find competitive rates that suit your financial situation.

Eligibility criteria for car loans generally include having a stable income, a good credit history, and the ability to provide proof of employment or business income. Lenders will assess your financial situation to ensure you can meet the repayment commitments.

How to Determine Your Deductible Amount

To accurately determine the deductible amount of your car loan interest, follow these steps:

1. Track Your Usage: Keep a detailed log of your vehicle's business and personal use. This can include odometer readings, travel logs, and any other relevant documentation.
2. Calculate Business Use Percentage: Calculate the percentage of total kilometres driven for business purposes. For example, if you drove 10,000 km total and 4,000 km were for business, your business use percentage is 40%.
3. Determine Deductible Interest: Multiply the total interest paid for the year by the business use percentage. If your total interest was $2,000, your deductible amount would be $800 (40% of $2,000).
4. Document and Claim: Keep all documentation and records to support your claim, and include the deductible interest on your tax return.

Tips and Considerations

Here are some expert tips to consider when claiming car loan interest as a tax deduction:

• Consult a Tax Professional: Tax laws can be complex, and it's always advisable to consult with a tax professional to ensure you're making accurate claims.
• Keep Accurate Records: Keeping detailed records of your vehicle's use and expenses will make it easier to substantiate your claims if needed.
• Review Your Loan Terms: Understand the terms of your car loan, including interest rate and repayment schedule, to better manage your finances.
