A Guide to Claiming Your Car Tax Deduction in Australia

By Panbo Ye, CFP^®, FCPA, SMSF Specialist Advisor · Founder of Everglow · Updated 13 October 2026

If you use your car as part of your work, you may have wondered whether you can claim a car tax deduction. In Australia, the answer is often yes—however, it is important to understand that this deduction is not typically available for your daily commute. The deduction is generally designed for specific travel you undertake to earn your income, such as driving between different work locations or visiting clients.

Navigating this area of tax with confidence begins with understanding who may be eligible. This is a foundational step in the sound management of your financial affairs.

Who May Be Able to Claim a Car Tax Deduction in Australia?

The rules for claiming a car tax deduction can depend significantly on your employment structure. The Australian Taxation Office (ATO) makes a clear distinction between employees and business owners, and each follows a different set of guidelines.

A fundamental principle to understand is that travel between your home and your regular place of work is almost always considered a private expense. This means the daily drive to and from the office is not usually deductible.

The Core Principle of Deductible Travel

The opportunity to claim a deduction may arise when your travel extends beyond a standard commute and is directly connected to earning your income. Depending on your role or business operations, this could include:

• Travel Between Workplaces: Driving from one job site directly to another during your workday.
• Client or Supplier Visits: Travelling from your office to meet with clients, patients, or suppliers.
• Income-Producing Activities: Using your car for tasks essential to your role, such as a real estate agent driving to property viewings or a tradesperson picking up materials.

Employees vs Business Owners

How you earn your income may shape how you can make a claim. An employee could be able to claim work-related car expenses on their individual tax return, provided the travel meets the ATO’s specific criteria. This is a common consideration for professionals who are required to be mobile throughout their day.

For business owners, including those operating as a sole trader, the vehicle is often treated as a business asset. You can explore this structure in our educational resource about what is a sole trader. Under these circumstances, you may be able to claim the business-use portion of your car’s running costs. This approach requires careful and consistent records to distinguish business journeys from private travel—a discipline that is the bedrock of good financial stewardship.

A core responsibility for anyone considering a car tax deduction is diligent record-keeping. The ATO requires you to substantiate your claims, and maintaining clear, current records is not only about compliance—it also reflects prudent financial management.

Choosing Your Method: Cents Per Kilometre or Logbook

When considering a tax deduction for your car, the Australian Taxation Office (ATO) provides two distinct pathways: the cents per kilometre method and the logbook method. It may be helpful to think of this as a choice between a straightforward, inclusive approach and a more detailed, itemised one.

Neither method is inherently superior—the most appropriate choice for your circumstances will likely depend on how much you drive for work and your discipline with record-keeping. A clear-eyed assessment of your own habits and travel patterns is a sensible first step.

This infographic offers a visual guide on how your work situation might influence your choice of method.

As illustrated, both employees and business owners may use either method. The best fit depends on your unique travel patterns and your capacity for keeping detailed records.

The Cents Per Kilometre Method

The cents per kilometre method is a refreshingly simple approach, often suitable for those who use their car for work occasionally. It allows you to claim a set rate for every business kilometre you travel, which may save you the task of collecting receipts for every running cost like fuel, insurance, or servicing.

For example, a busy medical professional in Sydney might drive between their main clinic and several hospitals. For the 2024-25 financial year, the ATO allows a claim of 88 cents per kilometre. This single rate is designed to cover fuel, registration, insurance, and depreciation, without the need to retain a shoebox full of receipts.

There is, however, a limit. You can only claim a maximum of 5,000 business kilometres per car, per year. This places a ceiling on your potential deduction, capping it at $4,400 for the 2024-25 income year.

Even with this simpler method, you cannot simply estimate your usage. The ATO will expect you to show how you calculated your total business kilometres, which could be done with diary notes or a simple log.

The Logbook Method

For those who use their car extensively for work, the logbook method is often a more suitable path. It is more detailed, but it may result in a larger tax deduction because it is based on your actual costs.

Here is how it generally works:

• Keep a Logbook: You will need to meticulously record all your car trips for a continuous 12-week period. The good news is that if your travel patterns remain consistent, this logbook can stay valid for up to five years.
• Calculate Your Business-Use Percentage: The logbook helps you determine what portion of your car travel is work-related. If you drove 1,000 kilometres in those 12 weeks and 700 of them were for business, your business-use percentage is 70%.
• Claim Your Actual Costs: You can then claim that percentage—70% in this example—of all your car's running costs. This may include fuel, oil, registration, insurance, loan interest, servicing, and depreciation. This can be particularly relevant for business owners, who might find our overview of small business tax deductions a helpful read.

Comparing Car Deduction Methods

To assist with your decision, this table breaks down the key differences between the two methods at a glance. It provides a useful way to see which approach might better suit your needs and record-keeping style.

Ultimately, choosing a method is a trade-off. The cents per kilometre method offers convenience, while the logbook method demands more effort but can deliver a significantly better financial result, particularly for high-mileage drivers.

Whichever path you take, knowing how to properly track business mileage is a key responsibility. The strength of your claim, regardless of the method, will always depend on the quality of your records.

Mastering the Logbook Method and Depreciation

If your work keeps you on the road regularly, the cents-per-kilometre method might feel restrictive. For those who travel extensively, the logbook method offers a pathway to a potentially more substantial car tax deduction. It demands more discipline, but the financial outcome can make the effort worthwhile.

This approach allows you to move beyond a simple flat rate and claim the actual business portion of your car’s total running costs. The entire method hinges on one key element: calculating an accurate business-use percentage. This figure determines what portion of your costs you may be able to claim.

Creating an ATO-Compliant Logbook

The heart of this method is the logbook itself. The Australian Taxation Office (ATO) requires you to keep a detailed log of your car's usage for a continuous 12-week period. This serves as a representative snapshot of your work-related travel.

To meet ATO requirements, each entry in your logbook generally needs to capture these details:

• The date the journey began and ended.
• The odometer readings at the start and finish of each trip.
• The total kilometres you travelled.
• A clear, specific reason for the trip (e.g., "Visit client ABC Pty Ltd for project meeting" or "Travel from main office to supplier warehouse").

Once you complete this 12-week log, you can calculate your business-use percentage. A well-kept logbook may remain valid for up to five years, but only if your driving patterns do not change significantly. If you change jobs, your role is altered, or you begin driving more or less for work, you will likely need to start a new logbook to reflect your new circumstances.

Understanding Car Depreciation as a Deduction

One of the significant components of the logbook method is the ability to claim depreciation—the decline in your vehicle’s value over time. It is an expense that accounts for the wear and tear on your car as a business-use asset.

The ATO has specific rules for this. You can generally start claiming depreciation on a car from the moment you begin using it for work purposes. The amount you can claim each year is based on the car’s cost and its "effective life," which is the ATO’s estimate of how long it can be reasonably used.

For example, if a car has an effective life of eight years, you could potentially claim 12.5% of its value each year using the straight-line method. The principle is similar to claiming the decline in value of other business tools, a topic you can read more about in our guide to the laptop depreciation rate.

It is important to be mindful of the car cost limit set by the ATO, which caps the value you can claim depreciation on. For the 2024–25 income year, this limit is $69,674. If you purchase a vehicle that costs more than this, your depreciation claim is based on this capped amount, not the total price you paid.

Instant Asset Write-Off for Businesses

For eligible businesses, the instant asset write-off scheme can provide a powerful, immediate deduction. Depending on the rules for a specific income year, a business might be able to claim the entire business-use portion of a vehicle's cost in the same year it was purchased and first used.

For instance, a small construction business purchases a new ute for $55,000. If their logbook shows 80% business use, they could potentially claim an immediate deduction of $44,000 ($55,000 x 80%), provided they meet the eligibility criteria for that year. This may have a significant impact on cash flow and reduce the year’s tax liability.

This concession has changed frequently over the years, so it is vital to check the specific thresholds and rules that apply in the financial year you acquire the vehicle. It represents a significant opportunity but requires careful planning.

Navigating the logbook method and depreciation requires a steady hand and an eye for detail. For many Australian professionals and business owners, however, it’s a worthwhile endeavour that aligns sound financial management with the reality of using a vehicle to earn an income.

Practical Examples for Australian Professionals

The rules are one thing, but seeing how they might apply in the real world can provide valuable context. Let's walk through a few scenarios to see how these car expense claims could play out for different Australian professionals.

Each situation is unique, which underscores the point that an appropriate tax strategy is always a personal one, tailored to individual circumstances.

These examples are simplified to illustrate the mechanics, not to serve as financial advice. They simply show how the two methods might be applied in different day-to-day working lives.

Example 1: The Medical Professional

Dr. Anya is a specialist with a private practice in Brisbane. Her work requires her to use her personal car to travel between her main clinic, the local hospital for patient rounds, and professional development seminars across the city. Over the year, her work-related travel totals 6,200 kilometres.

Let's look at her two options for claiming a car tax deduction.

• Cents Per Kilometre Method: This method is simple, but it’s capped at 5,000 kilometres. Even though Anya drove more, her claim is limited. At the 2024-25 rate of 88 cents per kilometre, her maximum deduction would be $4,400 (5,000 km x $0.88).

• Logbook Method: Anya decides the extra effort may be worthwhile and keeps a detailed logbook for 12 weeks. She also retains receipts for all her car's running costs—fuel, insurance, registration, servicing, and depreciation—which total $15,000 for the year. Her logbook establishes that 75% of her car's use is for work. Her potential deduction is therefore $11,250 ($15,000 x 75%).

For Dr. Anya, the discipline of keeping a logbook and receipts could result in a much larger, more accurate deduction. For healthcare workers, understanding every possible claim is vital, as you can see in our guide on what a nurse can claim on tax.

Example 2: The Construction Business Owner

Leo runs a small construction business in Western Sydney as a sole trader. He uses his ute constantly—visiting work sites, meeting with clients for quotes, and picking up tools and materials.

His ute is almost entirely a work vehicle, with only minimal private use on weekends. His logbook confirms a business-use percentage of 90%. The ute’s total running costs for the year amount to $12,000.

Under the logbook method, Leo’s potential deduction is $10,800 ($12,000 x 90%). It is his responsibility to ensure the logbook accurately reflects the small amount of private use, as the ATO expects this level of diligence.

For business owners with high-use commercial vehicles, the logbook method is not just another option; it is often the cornerstone of a sound tax strategy. It allows the claim to reflect the vehicle’s true contribution to generating income.

Example 3: The New Migrant IT Consultant

Mei recently moved to Melbourne and has launched her own IT consulting business. She is determined to build good financial habits from the very beginning. She uses her car to travel to client offices for software installations and troubleshooting.

Recognising the importance of solid records, Mei starts a digital logbook on day one. She diligently records every client visit, noting the purpose, date, and odometer readings.

After 12 weeks, her logbook establishes a business-use percentage of 60%. Her total car expenses for the financial year are $9,000. This disciplined approach means she can confidently claim a deduction of $5,400 ($9,000 x 60%) in her first year of business.

Mei’s story highlights the power of foresight. By embedding good record-keeping into her business operations from the start, she builds a resilient financial foundation, ensuring every claim she makes is robust and can be substantiated.

Navigating FBT and Other Key Business Considerations

When a business provides a car for an employee's private use, it enters the realm of Fringe Benefits Tax (FBT). This is a crucial area of financial stewardship for any business owner or not-for-profit leader, one that requires a calm, measured approach to meet compliance obligations.

A car fringe benefit can arise whenever a vehicle owned or leased by the business is available for an employee’s private use. This may be as simple as an employee garaging the car at or near their home, even if they do not drive it for personal trips. Understanding your potential FBT liability is a key responsibility, and the ATO provides two methods for its calculation.

Calculating Your FBT Liability

As an employer, you have two pathways to determine the taxable value of a car fringe benefit. The path you choose can have a significant impact on your final FBT bill, so it is a decision that warrants careful thought.

• The Statutory Formula Method: This is the more straightforward approach. It applies a flat statutory rate of 20% to the car's base value, regardless of how many kilometres it actually travels for work. While simple, it may lead to a higher FBT liability, particularly if the car is used heavily for business.

• The Operating Cost Method: This method is based on the actual costs of running the car. It demands a valid logbook to determine the business-use percentage. Your total operating costs are then reduced by this percentage, and FBT is paid only on the remaining private-use portion. For vehicles with high business use, this method often results in a substantially lower FBT bill.

Opportunities for Prudent Management

With thoughtful planning, you may be able to manage your FBT obligations effectively. Keeping a detailed logbook to prove a high business-use percentage is the most common and powerful strategy to lower your FBT liability under the operating cost method.

For many organisations, the administrative effort of maintaining a logbook is a small price to pay for the potential FBT savings it can unlock. It provides clear, defensible evidence of a car's role in the business, reflecting good governance and financial discipline.

Relief may also be available for certain types of organisations. Many not-for-profit organisations, for example, could be eligible for FBT concessions or even exemptions, which can free up vital resources for their core mission. You can find more details on our business advisory services page.

The Role of GST Credits

For businesses registered for Goods and Services Tax (GST), there's another important layer to consider. You can generally claim GST credits on the vehicle's purchase price and on its running costs, such as fuel, insurance, and servicing.

However, these credits must align with the vehicle's business use. If your logbook shows the car is used 70% for business purposes, you can typically claim 70% of the GST paid on its expenses. This reinforces just how central good record-keeping is—it is not only for income tax and FBT, but for your GST position as well.

This area of tax sees consistent regulatory focus. The FBT rate has held steady at 47% since 2017, and compliance is critical as ATO data-matching on vehicle claims has become increasingly sophisticated. You can get more information about the historical rates directly from the ATO. Properly integrating these rules can make a material difference to your organisation's financial health.
