Vehicle Tax Deductions for Tradies: What Can You Claim?

For most tradies, a vehicle is one of the biggest expenses — and one of the most valuable potential tax deductions. But vehicle deductions are also one of the most commonly audited areas by the ATO, because the line between business and private use is often blurred.

This article explains how vehicle deductions work for Australian tradies, the two methods for claiming, and why accurate records are essential. For tailored advice, accountants for tradies in Burleigh Heads can help ensure you're claiming correctly.

Business vs Private Vehicle Use

The fundamental rule is simple: only the business-use portion of vehicle costs is deductible. Private use — driving to the shops, picking up the kids, weekend trips — is not claimable.

The challenge is that most tradies use the same vehicle for both. A ute that takes you to a job site in the morning, the hardware store at lunch, and home in the evening has mixed use throughout the day. Establishing the business-use percentage accurately is essential.

Travel between home and your regular workplace is generally considered private. Travel between job sites during the day is generally business. If your "regular workplace" is home — for example, if you're a subcontractor who starts each day from home and travels to different sites — the picture may be different. The rules are specific to your situation.

The Two Methods for Claiming Vehicle Expenses

Cents Per Kilometre Method

The simplest method. You claim a set rate (determined by the ATO) per business kilometre, up to a maximum of 5,000 km per vehicle per year. The rate covers all running costs — fuel, registration, insurance, servicing, and depreciation — so you can't claim these separately.

You don't need receipts for expenses, but you do need to be able to show how you calculated the business kilometres. A diary or log of business trips is the usual evidence.

This method is simple but may understate your deduction if business use is high or running costs are significant.

Logbook Method

More accurate, but requires more record-keeping. You keep a logbook for 12 continuous weeks, recording every trip — business and private — with odometer readings. The logbook establishes the business-use percentage, which is then applied to all actual vehicle costs for the year.

Claimable costs include:

• Fuel (calculated from receipts or odometer readings and fuel efficiency)
• Registration and CTP
• Insurance
• Servicing, repairs, and tyres
• Depreciation (or interest and lease costs if financed)

A logbook is valid for five years, provided your business use doesn't change significantly. If your work patterns change — different routes, different clients, significantly more or less private use — you'll need a new logbook.

Which Method Is Better?

It depends on your circumstances. For a tradie who does 15,000 business kilometres a year with high running costs, the logbook method usually produces a larger deduction. For a tradie who does 3,000 business kilometres a year, cents per kilometre may be simpler and sufficient.

An accountant can help you compare the two methods based on your actual usage and costs — and may recommend keeping a logbook even if you use the cents-per-kilometre method, so you have the option to switch if it becomes more advantageous.

Record Keeping: Why It Matters

Vehicle deductions are a focus area for the ATO because records are often incomplete. Without a logbook or a record of business kilometres, claims can be disallowed — even if the business use was genuine.

Essential records include:

• A logbook (if using the logbook method) or a diary of business trips (if using cents per kilometre)
• Fuel receipts or a record of odometer readings and fuel purchases
• Receipts for registration, insurance, servicing, tyres, and repairs
• Odometer readings at the start and end of the financial year

Vehicle logbook apps make this easier — they track trips automatically using GPS and can generate the reports you need at tax time.

Different Vehicle Arrangements

How you claim also depends on how the vehicle is owned and used:

• Vehicle owned personally: you claim the deduction on your individual tax return for the business-use portion.
• Vehicle owned by a company or trust: the entity claims the costs, but private use may create a fringe benefits tax (FBT) obligation. This is more complex — seek advice.
• Vehicle leased: lease payments are deductible, but the treatment differs from ownership. Understand the implications before choosing to lease or buy.

Why Professional Tax Advice Is Useful

Vehicle deductions are one of the areas where professional advice pays off. An accountant who understands trades businesses can:

• Help you choose the most appropriate method
• Ensure your logbook meets ATO requirements
• Calculate the deduction accurately
• Advise on vehicle ownership and FBT implications
• Identify related deductions — tool storage in the vehicle, for example

For tradies on the Gold Coast, accounting services in Burleigh Heads can handle your vehicle deductions as part of a broader tax return service.
