Everything Australian tradies need to know about the $20,000 instant asset write-off before it drops to $1,000 on 1 July 2026 — what qualifies, the trap most articles bury, and the records the ATO actually wants to see.
The $20,000 instant asset write-off (IAWO) lets eligible Australian small businesses immediately deduct the full cost of business assets costing under $20,000 each. From 1 July 2026, the threshold is legislated to drop to $1,000 — a 95% cut — unless the government extends it again. To qualify, your business must have aggregated turnover under $10 million, and each asset must be first used or installed ready for use between 1 July 2025 and 30 June 2026. The $20,000 limit applies to the total cost of the asset, not just the business-use portion — a critical trap many tradies don't realise until tax time. Both new and second-hand assets qualify. This article covers what tradies can actually claim, the one-tonne rule for utes and vans, the records the ATO requires you to keep for five years, and the most common mistakes that cost tradies thousands.
Most tradies hear about the instant asset write-off, nod, and assume their accountant will sort it out at tax time. That's fair enough — until you realise the difference between getting it right and getting it wrong is somewhere between $5,000 and $20,000 in deductions, and the deadline that decides which side you land on is 30 June 2026.
After that, the threshold drops from $20,000 to $1,000 per asset. That's a 95% cut. Until then, every tool, ute, trailer, and piece of plant you buy under $20,000 can be deducted in full this financial year — but only if you get a few details right that most articles don't bother to spell out properly.
Here's what's actually true, what's actually changing, and the trap that catches more tradies than any other.
Normally when you buy a business asset — a compressor, a trailer, a ute — you can't deduct the full cost in the year you buy it. You have to spread the deduction across the asset's "effective life" through depreciation. A $15,000 compressor might give you a $3,000 deduction in year one, then a smaller amount each year after that.
The instant asset write-off changes that. If your business is eligible and the asset costs less than $20,000, you can deduct the entire cost in the year you first use it. That's the whole pitch: a bigger deduction, sooner, with less paperwork at tax time.
For a tradie running a small business, this typically translates to a real cash-flow win: lower taxable income this year, lower tax bill, more money in the business account when you actually need it.
The $20,000 threshold isn't permanent. Parliament passed the Treasury Laws Amendment (Strengthening Financial Systems and Other Measures) Act in November 2025, which extended the $20,000 limit through to 30 June 2026. Without that legislation, the threshold would have already reverted to the ongoing legislated amount of $1,000.
From 1 July 2026, unless the government legislates another extension, the threshold drops back to $1,000 per asset. There has been no public commitment to extending it again.
In practical terms, that means a $15,000 compressor bought and operational by 30 June 2026 gives you the full $15,000 as an immediate deduction. The same compressor bought a week later gives you $1,000 as an immediate deduction, with the rest depreciated through the small business pool over multiple years.
It's the same compressor either way. The difference is timing.
To use the instant asset write-off, your business needs to tick three boxes:
Sole traders, partnerships, trusts, and small companies are all eligible if they meet these conditions. There's no requirement to be GST-registered, though the GST treatment of the $20,000 limit changes depending on whether you are or aren't (more on that below).
The eligible asset list is broad. For tradies, the following all qualify provided each individual item costs under $20,000 and is used in the business:
Both new and second-hand assets qualify on the same basis. A $14,000 used trailer from another tradie counts the same as a $14,000 trailer from a dealer. This is one of the most underused parts of the rule — second-hand kit can stretch your $20,000 a long way.
This is the single most expensive misunderstanding tradies have about the instant asset write-off, and it comes straight from an example the ATO publishes on its own website.
Here's the scenario the ATO uses (paraphrased, with names changed):
Daryl runs a small electrical business with turnover under $10 million. He buys a ute for $40,000. He estimates he'll use the ute 40% of the time for business and 60% for private use.
The business-use portion of the cost is $40,000 × 40% = $16,000. That's under the $20,000 threshold. So you might assume Daryl can claim the full $16,000 immediately under the instant asset write-off.
He can't. The $20,000 threshold applies to the total cost of the asset ($40,000), not the business-use portion. Because the total cost exceeds $20,000, the IAWO is not available at all. Daryl has to add the $16,000 business portion to the small business depreciation pool and claim it gradually over multiple years.
Read that twice. The implication is huge.
If you're considering a part-business, part-private asset — the most common example being a ute — and the total purchase price is over $20,000, you do not get the instant asset write-off. The fact that your business-use portion is under $20,000 doesn't matter. The asset is over the limit.
The fix is straightforward but easy to miss: if you want the IAWO benefit on a mixed-use asset, the total cost (not just your business-use portion) needs to come in under $20,000.
For a vehicle, this often means looking at the second-hand market or a dedicated work vehicle that you're confident is overwhelmingly business-use. For tools and equipment, it's rarely an issue because most tradie kit is either fully business or comfortably under the limit.
This is the second most common trap, and it's a timing one.
The ATO requires the asset to be "first used or installed ready for use for a taxable purpose" between 1 July 2025 and 30 June 2026 to qualify under the current $20,000 threshold.
Buying the asset isn't enough. Paying for it isn't enough. Even taking delivery isn't enough on its own. The asset needs to be operational and either in use or sitting ready for use in your business by 30 June.
A few practical examples:
The practical takeaway: if you're financing the purchase, finance industry guidance suggests a chattel mortgage typically takes three to five weeks from first broker call to settlement. To be confident the asset is operational by 30 June, most tradies need to start the process by mid-to-late May at the latest. Settling on the last business day of June carries real risk — system delays, missing documents, or used-asset valuations can push the deal into July and cost you the deduction entirely.
The $20,000 limit applies to each individual asset, not your total spending for the year. There's no cap on how many separate assets you can claim under the IAWO.
For example, in the same financial year you could claim:
That's a total of $39,500 in immediate deductions in one financial year — provided each asset is individually under $20,000, each is used in the business, and each is operational by 30 June.
What you can't do is split a single $25,000 asset into "$13,000 of frame" and "$12,000 of attachments" to bring it under the threshold. The asset is what it is. If it costs $25,000 as a working unit, it goes into the depreciation pool.
Vehicles are where things get a bit technical, but it's worth understanding because the rules favour tradies more than they favour most other small businesses.
The ATO splits vehicles into two categories for tax purposes:
A "car" is a vehicle designed mainly to carry passengers, with a load capacity under one tonne and fewer than nine passenger seats. Most sedans, SUVs, and dual-cab utes with smaller payload ratings fall into this category.
Cars are subject to the car limit, which for 2025–26 is $69,674. The car limit caps the cost you can depreciate. Critically, a car costing $30,000 is over the $20,000 IAWO threshold — so the IAWO doesn't apply, and the business-use portion goes into the small business pool.
Vehicles designed primarily to carry goods, with a load capacity of one tonne or more, are not subject to the car limit. Many tradie utes, vans, and light trucks fall into this category — Toyota HiAce vans, Toyota HiLux 4x4 single-cab utes, Ford Transit vans, and similar commercial-spec vehicles.
For these vehicles, the only limit that applies is the IAWO threshold itself: under $20,000 (total cost, see the trap above), and you can claim the full business-use portion in the year of first use.
To check whether your vehicle qualifies as a commercial vehicle, look at the gross vehicle mass (GVM) and basic kerb weight on the compliance plate. Payload capacity = GVM minus basic kerb weight. If that figure is one tonne (1,000kg) or more, you're outside the car limit. Always check the specific build of your vehicle — payload can vary between trims of the same model.
How you measure whether an asset is "under $20,000" depends on whether your business is registered for GST.
This single detail can shift an asset from "no claim" to "eligible" or vice versa, especially for items priced just on either side of the threshold. It's worth asking your supplier for a GST-exclusive figure before assuming an asset is too expensive.
Claiming the IAWO is one thing. Substantiating it if the ATO asks is another. The general rule is that you need to keep records for five years from the later of either when you first claimed the deduction or when the asset was disposed of.
For each asset claimed under the IAWO, the ATO will expect to see:
Recent ATO Administrative Review Tribunal decisions have repeatedly thrown out tradie deduction claims not because the deductions were illegitimate, but because the records weren't contemporaneous — meaning they weren't created at the time the events happened, but reconstructed later. Logbook entries written months after the fact, estimates without supporting documents, and diary entries that contradict service records or invoices have all been disallowed.
The pattern is clear: the deduction is only as strong as the records behind it.
The "evidence the asset was first used in the business by 30 June" requirement sounds simple, but it's where a lot of tradies come unstuck. Six months later, when your accountant asks for proof, "I'm pretty sure I used it on the Henderson job" isn't documentation. A photo with a timestamp is.
Most tradies who keep good records use one of three approaches:
Whichever way you go, the point is the same: get into the habit of recording the date an asset is first used in your business, while it's happening, not after the fact.
A few categories of asset are specifically excluded:
Assets costing $20,000 or more aren't useless from a tax perspective — they're allocated to the small business depreciation pool and depreciated at 15% in the first year, then 30% each year after that.
If you previously claimed an asset's full cost under the IAWO in an earlier year and then later spend money improving it (a "second element" cost in ATO language), that improvement cost can also be claimed immediately — as long as:
A practical tradie example: you wrote off a $14,000 compressor in the 2024–25 financial year. In April 2026 you spend $4,500 upgrading it with a new motor and pressure tank. That $4,500 improvement is eligible to be claimed immediately under the IAWO in the 2025–26 year.
No. The $20,000 limit applies to the total cost of the asset, not the business-use portion. Even if you only use the ute 40% for business, the total cost ($40,000) exceeds the threshold and the IAWO doesn't apply. The business-use portion goes into the small business depreciation pool instead.
Yes. Both new and second-hand assets qualify on the same basis, provided they meet all other eligibility conditions. A $14,000 second-hand trailer purchased from another tradie qualifies the same as a $14,000 new trailer from a dealer.
No, but only the business-use percentage is deductible. If you use a $15,000 piece of equipment 80% for business and 20% for private use, you can claim $12,000 under the IAWO (the business-use portion). You'll need records to support your business-use percentage.
No claim for the 2025–26 year. The asset must be first used or installed ready for use by 30 June 2026 to qualify under the $20,000 threshold. Asset first used from 1 July 2026 onwards falls under the new $1,000 threshold (unless legislation changes).
You need to be carrying on a business, which generally requires an ABN. The IAWO is available to small business entities — sole traders, partnerships, trusts, and companies — that meet the eligibility criteria.
There's no cap on the number of separate assets. The $20,000 limit applies per asset. You could claim ten assets at $19,000 each in the same year if they all qualify and are operational by 30 June.
It goes into the small business depreciation pool. The business-use portion is depreciated at 15% in the first year and 30% each year after that. You still get the deduction, just spread over multiple years.
Unknown. Industry bodies have called for certainty without success, and as of April 2026 there is no government commitment to extending it. The legislated threshold from 1 July 2026 is $1,000. Most accountants and finance brokers are advising clients to plan as if 30 June 2026 is a hard deadline.
Only if your business genuinely needs the equipment. The general principle is that buying assets you don't actually need, purely to generate a tax deduction, rarely makes commercial sense — you're spending real money to save a percentage of it in tax. The IAWO is a timing benefit on purchases you were going to make anyway. If the equipment is on your list and the cash flow works, then yes, getting it operational before 30 June secures the deduction at the higher threshold.
