Can You Claim Depreciation on Business Vehicles?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you can claim depreciation on motor vehicles used for business purposes in Australia. Under **Division 40 of ITAA 1997**, vehicles are considered depreciating assets. The depreciation deduction is calculated based on the effective life of the vehicle and the percentage of business use. Consult with your accountant to ensure you apply the correct method.

Claiming depreciation on motor vehicles used for business is a common tax deduction available to Australian business owners. Under Division 40 of ITAA 1997, motor vehicles are classified as depreciating assets, which means you can claim a depreciation deduction based on the decline in value over time. The key is to determine the proportion of business use and apply the correct depreciation method, such as the diminishing value or prime cost method.

To see how this plays out, consider a small business owner who purchases a new delivery van for $40,000. If the van is used 80% for business, you can claim depreciation on that percentage. Using the diminishing value method, assuming an effective life of 8 years, the first-year depreciation might be around $5,000. At a 30% corporate tax rate, this could reduce your tax liability by $1,500 in the first year.

In our experience reviewing thousands of properties across Australia, many business owners overlook the importance of keeping accurate logbooks to substantiate their claims. Another frequent issue is not updating the effective life of vehicles, often leading to incorrect depreciation rates. Additionally, some assume any vehicle expense is deductible without considering the business-use percentage.

The answer can differ depending on your situation. For instance, if your vehicle is used for both personal and business purposes, only the business-use portion is deductible. Vehicles acquired second-hand may have different effective lives, impacting depreciation. If you're a sole trader, the rules may vary compared to a company structure. Furthermore, luxury car limits can affect the depreciation claim for high-value vehicles.

Getting professional advice is crucial because the specifics of your situation—such as the method of purchase, business structure, and vehicle use—can significantly impact your tax outcome. A Chartered Quantity Surveyor and a tax accountant can ensure you're claiming the maximum allowable deduction without falling foul of ATO regulations.

  • Frequently Asked Questions

    Can I claim depreciation on a leased vehicle?

    No, if you lease a vehicle, you typically cannot claim depreciation. Instead, lease payments are deductible as an expense, based on the business-use percentage.

    How do I determine the business-use percentage?

    You must maintain a logbook for at least 12 continuous weeks, detailing business and personal use. This percentage is used to calculate your deductible expenses.

    What if I use the vehicle for both personal and business purposes?

    You can only claim depreciation on the business-use portion. Personal use must be excluded from your deduction calculations.

    Are there state-specific rules for vehicle depreciation?

    While most rules are federal, check for any state-specific incentives or requirements that might apply, especially if your vehicle is used for interstate business.

    How does vehicle depreciation affect my tax return?

    Depreciation reduces your taxable income, thus lowering your tax liability. Ensure your claim is accurate to avoid adjustments during the ATO review.
