As the year winds down, a lot of WA business owners start weighing up a familiar question: should we buy that ute, trailer or machine now, or wait? Done right, an end-of-year purchase can bring forward a tax deduction and get productive equipment working sooner. The key is understanding the instant asset write-off and getting the timing and the finance right.
What the instant asset write-off does
In simple terms, it lets an eligible small business immediately deduct the business-use portion of an eligible asset's cost — up to a threshold — in the year the asset is first used or installed ready for use, instead of claiming smaller depreciation amounts over several years. The headline threshold has been $20,000 for small businesses with aggregated turnover under $10 million, applied on a per-asset basis, so you can potentially write off several qualifying assets in the same year.
Timing is everything
To claim the deduction in a given financial year, the asset generally needs to be first used or installed ready for use by the cut-off date — typically 30 June. That sounds like plenty of time, but equipment with delivery lead times, fit-outs or commissioning can slip past the line. A machine sitting on a truck or waiting on an install isn't "ready for use." If you're eyeing a purchase, starting the finance conversation early means you're ready to move the moment the right asset appears — not scrambling in late June.
Where finance fits in
Here's the part business owners often miss: you can finance the asset and still claim the write-off. Because a chattel mortgage means you own the asset from day one, you can claim the eligible deduction while keeping your cash in the business rather than paying the full price up front. That's the best of both worlds — the tax benefit now, the equipment now, and your working capital intact.
- Finance the purchase with a chattel mortgage and keep your cash free for wages, stock and the quiet January period.
- Claim the eligible write-off in the year the asset is installed and ready.
- Spread the repayments over the asset's working life so it pays for itself as it earns.
Why financing can beat paying cash
It feels counter-intuitive, but draining your bank account to buy an asset outright — just to claim a deduction — can leave you short when you need cash most. Financing lets you capture the same deduction while your cash stays available for the day-to-day. For many businesses, the repayments are comfortably covered by the extra work the new asset brings in. It's the difference between a purchase that strains the business and one that grows it.
Common mistakes to avoid
- Leaving it too late. Order early enough that the asset is installed and ready by the cut-off, not just paid for.
- Assuming every vehicle qualifies in full. Passenger vehicles are subject to a car limit that caps the claim; genuine work utes and machinery are treated differently. Check before you buy.
- Forgetting business-use apportionment. If an asset is used partly privately, your claim is reduced accordingly — keep records.
- Buying something you don't need just for the deduction. A write-off reduces tax; it doesn't make an unnecessary purchase free. Buy what the business actually needs.
What if the asset costs more than the threshold?
Bigger-ticket gear above the write-off threshold doesn't miss out entirely — it's generally depreciated under the normal small-business rules over time, often through a simplified depreciation pool, and it's just as financeable. The deduction is spread rather than immediate. For a fuller picture of structures and what you can fund, see our guide to equipment finance in WA.
A simple end-of-year checklist
- Confirm your eligibility and the current threshold with your accountant.
- Decide what the business genuinely needs — a work ute, an excavator, a fit-out.
- Get finance pre-approved so you can buy the moment you find the right asset.
- Make sure it's delivered, installed and ready for use before the cut-off.
- Keep your invoices and usage records for your accountant.
The bottom line
The instant asset write-off can be a genuine win for a WA small business — but only if the asset is eligible, installed in time, and financed in a way that protects your cash flow. Confirm the current rules with your accountant, line up your finance early, and you can head into the new year with the right equipment and a healthier tax position. Whether it's a work ute, an excavator or a full fit-out, talk to PTR Finance Group and we'll get you sorted before the hammer falls on 30 June.
Frequently Asked Questions
What is the instant asset write-off?
It lets eligible small businesses immediately deduct the business-use portion of an eligible asset's cost, up to a threshold, in the year the asset is first used or installed ready for use — rather than depreciating it over several years. The $20,000 threshold has applied for small businesses with turnover under $10 million; thresholds and dates change, so confirm the current rules with your accountant or the ATO.
Who can claim it?
Generally small businesses with an aggregated turnover under the relevant threshold (commonly $10 million) that use the simplified depreciation rules. Eligibility, thresholds and timing are set by the ATO and can change year to year, so check your position before you buy.
Can I still claim it if I finance the asset?
Yes — financing the purchase with a chattel mortgage doesn't stop you claiming the write-off, because you own the asset. In fact, financing lets you get the deduction and the equipment now while keeping your cash in the business. Confirm the detail with your accountant.
Does the asset have to be installed by a certain date?
Yes. To claim in a given year the asset generally must be first used or installed ready for use by the cut-off date (typically 30 June for the financial year). Ordering early matters when there are delivery lead times — leave enough runway.
What if my asset costs more than the threshold?
Assets above the threshold don't get the full immediate write-off but are generally depreciated under the normal rules (often via a small business pool). The asset is still financeable and still deductible over time — it's just the timing of the deduction that differs.
