Instant Asset Write-Off: What Still Qualifies in 2026

The instant asset write-off lets eligible small businesses claim an immediate deduction for the full cost of a qualifying asset in the year it's first used or installed ready for use, rather than depreciating it gradually over several years. It's a genuinely useful cash-flow tool — but the rules around eligibility, thresholds, and timing shift regularly, so it's worth understanding how it works rather than assuming last year's settings still apply.

How the write-off actually works

Normally, when you buy an asset for your business, you can't deduct the whole cost at once. You claim depreciation — a portion of the cost each year across the asset's effective life — which spreads the tax benefit out. The instant asset write-off changes that for eligible assets under a threshold: you claim the entire cost as a deduction in the year the asset is first used or installed ready for use in the business.

The benefit is timing and cash flow, not free money. You're bringing forward a deduction you'd have received eventually anyway, which reduces your taxable income sooner and can meaningfully help in a year where you've invested in equipment. Because it's a deduction, its value depends on your tax position — it only helps to the extent you have income to offset.

The eligibility rules to check

Several conditions all have to be met, and each is worth confirming against the ATO's current guidance rather than memory, because the settings change from year to year:

• Your business has to qualify. Eligibility is tied to aggregated annual turnover being under a threshold that the ATO sets. "Aggregated" matters — it can include the turnover of connected or affiliated entities, so a group of related businesses needs to look at the combined figure.
• The asset has to be under the threshold. There's a per-asset cost limit, and it applies to each asset individually — so you can potentially write off several assets in a year, each under the cap. Both the turnover threshold and the per-asset limit are numbers the ATO publishes and revises, so check the current figures.
• Timing is critical. The asset must be first used, or installed ready for use, within the relevant income year — not merely ordered or paid for. An asset bought late in the year but not delivered and installed until the next year is claimed in that next year. The write-off has also operated with specific date windows in the past, so confirm the current dates apply to your purchase.
• It has to be a business asset. The deduction is for the business-use portion. If an asset is used partly for private purposes, you claim only the business-use share.

What typically qualifies — and what doesn't

Broadly, the write-off applies to depreciating assets: tools, machinery, equipment, computers and technology, office furniture, and vehicles (subject to a separate car limit that caps the deduction for passenger vehicles). Both new and second-hand assets can be eligible.

Some things fall outside it. Trading stock isn't a depreciating asset, so it doesn't apply. Certain assets have their own specific rules — capital works and buildings, for instance, are treated separately. Assets leased out to others, horticultural plants, and some other categories are excluded. And the car limit means a more expensive passenger vehicle can't be written off in full even if it otherwise qualifies. If an asset costs more than the threshold, it doesn't get a partial instant write-off — it goes into normal depreciation instead.

Practical points that trip people up

• Don't buy for the deduction alone. A write-off reduces your tax, but you're still spending real money on the asset. It only makes sense if you genuinely need the asset for the business; a deduction never returns more than the tax on the amount spent.
• Watch the installed-ready-for-use test near year-end. If you're timing a purchase to fall in a particular income year, the deadline is when it's ready to use, not when you pay. Supply delays can push the claim into the following year.
• Keep your records. You need the invoice, the date it was first used or installed, and evidence of the business-use proportion. Good record-keeping is what turns an eligible purchase into a defensible claim.
• GST interacts with the figure. If you're registered for GST, the cost you use for the threshold and the deduction is generally the amount excluding the GST you can claim back. If you're not registered, it's the GST-inclusive cost.

Confirm the current settings before you rely on it

The instant asset write-off has been extended, adjusted, and had its thresholds changed repeatedly over the years, and its future beyond any given income year often depends on legislation that isn't settled until close to the time. Because of that, the single most important step is to check the current threshold, turnover limit, and eligibility dates on the ATO website or with your accountant before you count on a claim. This is general information, not tax advice for your specific circumstances — your accountant can confirm how the rules apply to a particular purchase and your business structure.
