Instant Asset Write-Off for Vehicles: How It Works in 2026

The instant asset write-off lets small businesses immediately deduct assets costing less than $20,000 each, rather than depreciating them over several years. For vehicles, the ute or car itself usually exceeds this threshold. But accessories, fit-outs, and attachments can each qualify as separate assets. The concession runs until 30 June 2026 for businesses with aggregated turnover under $10 million.

Why vehicle buyers need to understand this before 30 June

The $20,000 instant asset write-off has been extended year by year since 2023, most recently confirmed in the 2025-26 federal budget. There is no guarantee it will be extended again after 30 June 2026. For anyone buying a work vehicle this financial year, the structure of the purchase directly affects how much you can deduct immediately versus over several years.

A mid-spec 4x4 dual cab ute costs between $55,000 and $70,000 before on-road costs. That is well above the $20,000 threshold. But a vehicle purchase often includes thousands of dollars in accessories and fit-outs that, if structured correctly, can each be written off immediately as separate assets.

How the instant asset write-off works

The rules are straightforward but the detail matters.

Eligibility: Your business must have an aggregated turnover of less than $10 million for the income year. This covers sole traders, partnerships, companies, and trusts that meet the threshold.

Per-asset threshold: Each asset must cost less than $20,000. If you are registered for GST, you use the GST-exclusive cost. If you are not registered for GST, you use the GST-inclusive cost. A $19,800 asset (before GST) qualifies. A $20,100 asset does not.

Timing: The asset must be first used or installed ready for use between 1 July 2025 and 30 June 2026. Ordering is not enough. The asset must be delivered, installed, and ready to go before the deadline. A canopy ordered on 25 June but fitted on 3 July does not qualify for the 2025-26 year.

What qualifies: Any depreciable asset used for business purposes. This includes vehicles, tools, equipment, technology, furniture, and fittings. The asset does not need to be new.

Vehicles and the $20,000 threshold

Most work vehicles exceed $20,000, which means the vehicle itself goes into the simplified depreciation pool rather than being written off immediately. Here is how common business vehicles compare against the threshold.

The only vehicles that typically qualify are older used vehicles purchased for under $20,000 (GST-exclusive if registered). A 2018 HiLux with 180,000 km might come in under the threshold. Everything else goes into the depreciation pool.

Accessories that qualify as separate assets

This is where the instant asset write-off becomes valuable for vehicle buyers. Accessories and fit-outs purchased separately from the vehicle are treated as individual assets. If each one costs less than $20,000, each one qualifies for immediate write-off.

A typical fit-out on a new work ute might include a canopy ($4,000), toolbox ($1,500), bull bar ($2,200), tow bar ($900), and ladder rack ($800). That is $9,400 in accessories, each written off immediately in the year of purchase. On a 25% marginal tax rate, that is roughly $2,350 back at tax time that you would otherwise recover over several years through depreciation.

How to structure the purchase

The way you buy matters as much as what you buy. The ATO treats accessories as separate assets only if they are genuinely separate from the vehicle purchase.

Get separate invoices. If you buy a ute and a canopy from the same dealer in one transaction with one invoice, the ATO may treat the canopy as part of the vehicle's cost. Ask the dealer to invoice the vehicle and each accessory separately. Most dealers will do this without issue.

Buy accessories after settlement. The safest approach is to purchase the vehicle first, take delivery, and then buy and install accessories separately. This creates a clear paper trail showing they are distinct assets.

Do not bundle into the finance amount. If you are financing the ute through a chattel mortgage or hire purchase, keep accessories off the vehicle finance contract where possible. Finance the ute, pay for accessories separately (or finance them on a separate facility).

Keep records. For each accessory, keep the tax invoice showing the item, the cost (GST-exclusive if registered), the date of purchase, and the date it was installed and ready for use.

What happens to the vehicle itself

Assets costing $20,000 or more go into the simplified depreciation pool (for businesses under $10 million turnover). The pool works like this:

• First income year: Deduct 15% of the asset's cost
• Each year after: Deduct 30% of the pool's opening balance

On a $65,000 ute, that gives you a $9,750 deduction in the first year and $16,575 in the second year. The deduction continues at 30% of the remaining balance each year until the pool is below $20,000, at which point the entire remaining balance can be written off.

The car cost limit

For vehicles the ATO classifies as "cars" (carrying capacity under 1 tonne), the car cost limit of $69,674 for 2025-26 caps the amount you can depreciate. Most popular dual cab utes exceed 1 tonne carrying capacity and are classified as "other vehicles", meaning the full purchase price is depreciable with no cap. We explain the distinction in detail in our ute tax deductions guide.

Before 30 June 2026: a checklist

If you are buying a work vehicle and want to maximise your deductions this financial year, here is what to do before the deadline.

• Confirm your turnover is under $10 million for 2025-26
• Order the vehicle now to allow for delivery lead times (some models have 8-12 week waits)
• Plan accessories separately and get quotes with separate invoicing
• Ensure delivery and installation of all assets before 30 June. "Installed ready for use" is the test, not "ordered" or "paid for"
• Keep all tax invoices with dates, amounts, and GST breakdowns
• Talk to your accountant about whether the simplified depreciation pool or general depreciation rules are better for your situation

The 30 June deadline is firm. If the write-off is not extended for 2026-27, the threshold may revert to $1,000 per asset, which would eliminate the accessory strategy entirely.
