Buying a truck is a big investment, and the instant asset write-off is one of the reasons many operators time a purchase carefully. The rules shift year to year, so it pays to understand the basics before you sign anything. At Overdrive Truck Finance, our broker Simon Kendrick compares 80+ banks and non-bank lenders on one application so eligible operators can fund the right asset and get it working before the financial year closes.

Key highlights

  • Instant asset write-off thresholds and eligibility change year to year, so confirm current rules first
  • A truck can still be financed and potentially claimed under a write-off in the same year
  • The asset generally needs to be installed and ready for use, not just ordered
  • Chattel mortgage structures often suit operators wanting to claim depreciation
  • Always confirm your position with your accountant before you commit

What is the instant asset write-off for trucks?

The instant asset write-off lets eligible businesses claim an immediate deduction for the cost of an asset, rather than depreciating it slowly over many years. For truck operators, that can mean a prime mover, rigid, tipper, or trailer potentially qualifying, provided it sits under the threshold that applies at the time and your business meets the turnover test. The scheme has been extended, adjusted, and re-thresholded repeatedly by successive governments, so the figure that applied two years ago may not apply now. Because the rules genuinely change, the single most useful thing you can do is confirm the current threshold and eligibility with your accountant before you commit to a purchase. Getting that timing right can influence how you structure the buy.

Can you finance a truck and still claim the write-off?

Yes, in many cases. A common misconception is that you have to pay cash to claim an instant asset write-off. Under a chattel mortgage, your business generally takes ownership of the truck from day one while the lender holds security over it, which can mean the asset is treated as yours for depreciation and write-off purposes even though you are repaying it over time. That combination is part of why chattel mortgages are so popular with owner-drivers and fleets. It can let you preserve working capital, keep the truck earning, and still potentially access an immediate deduction in the relevant year. The exact tax treatment depends on your circumstances, the finance structure, and current legislation, so this is squarely a conversation to have with your accountant.

Timing: when does the truck need to be ready for use?

One detail trips a lot of operators up. To claim a write-off in a given financial year, the asset generally needs to be first used or installed ready for use within that year, not merely ordered or paid a deposit on. For trucks with long lead times, custom bodies, or trailers being built, that distinction matters enormously. If you place an order in June expecting a delivery in August, you may find the claim falls into the following year. Planning backwards from your delivery date, and lining up finance approval early, can make the difference. This is one reason operators start the finance conversation well before they need the keys, so approval is ready and settlement can happen when the truck is genuinely available.

Which finance structure suits a write-off claim?

For operators focused on depreciation and write-off, a chattel mortgage is often the go-to structure because ownership typically sits with your business. A commercial hire purchase can also work in similar ways for some borrowers. Rental or operating-lease style products, by contrast, usually mean the financier retains ownership, so the tax treatment differs and the write-off may not apply in the same way. None of this is one-size-fits-all. The right answer depends on whether you are on cash or accruals accounting, your GST position, your projected profit, and how long you plan to keep the truck. Because Overdrive compares a wide panel, the broker can match the structure your accountant recommends to a lender comfortable with it and your industry.

What lenders look at when funding the truck

The write-off is a tax question, but the finance still has to be approved on its own merits. Lenders assessing a truck loan generally look at your ABN and GST registration length, trading history, the age and type of vehicle, the loan amount, and whether you can show the truck will generate income. Owner-drivers with a clean record and a couple of years trading often have strong low-doc options. Newer businesses, or those buying older heavy vehicles with high kilometres, may face more questions or need supporting documents. Presenting a tidy application, contract of sale, and clear picture of your work helps. A broker who knows which lenders are comfortable with your asset age and industry can save you knock-backs on credit.

Common pitfalls to avoid

The biggest mistake is assuming the write-off will apply without checking the current rules, then structuring a purchase around an outdated threshold. A close second is leaving finance to the last minute, only to have delivery or approval slip past 30 June. Others over-focus on the tax benefit and buy more truck than the work supports, straining cash flow once the novelty of the deduction fades. Remember that a write-off reduces taxable income, it does not hand you free money, and you still repay the finance in full. Treat the deduction as a helpful bonus on a truck you genuinely need, confirm the numbers with your accountant, and make sure the repayment comfortably fits your monthly cash flow.

If a new or replacement truck is on your radar this year, it is worth getting your finance sorted early so timing never becomes the obstacle.
