The Instant Asset Write-Off Rule Most Business Owners Miss

What qualifies for the write-off (and what doesn't)

The instant asset write-off lets eligible small businesses claim the full cost of an asset as a deduction straight away, instead of depreciating it over several years. For the 2025-26 income year, three things needed to line up.

• Your business needed an aggregated annual turnover under $10 million.
• The asset had to cost less than $20,000 (excluding GST if you're registered).
• And, it could be brand new or second-hand, with no limit on how many assets you claim, as long as each one sat under the threshold on its own.

That last point is easy to miss when you're going back through the year's purchases. Three utes at $18,000 each can all be written off in full, because the limit applies per asset, not as a combined cap across everything you bought.

If something you bought cost $20,000 or more, it doesn't qualify for the instant write-off. It goes into your small business pool instead, and depreciates at 15% in the first year and 30% each year after.

You can check the ATO's full eligibility criteria to confirm whether a purchase actually qualifies before you finalise your return.

The single date that could cost you the deduction

This is where the scheme catches people out, and it's worth revisiting now if you bought anything close to the end of the financial year. The ATO required the asset to be first used, or installed ready for use, for a taxable purpose between 1 July 2025 and 30 June 2026. Paying for it, having it delivered, or even having it sitting in your workshop wasn't enough on its own.

If you ordered equipment in mid-June and your supplier couldn't deliver and set it up until after 30 June, it doesn't count on your 2025-26 return, even though you paid the invoice before the deadline. That deduction moves to your 2026-27 return instead.

A few checks are worth doing before you lodge:

• Confirm the actual delivery and installation date for anything bought close to 30 June, not just the invoice date.
• Check your paperwork. Invoices, delivery dockets, and installation records are what prove when an asset was ready for use.
• If a purchase landed just after 30 June, don't force it into this year's return. It belongs in 2026-27 instead.
• For anything you're planning to buy before the next 30 June, apply the same rule early. Order with enough buffer that delivery and setup happen well before the deadline, not on the day.

Why you can finally stop guessing year to year

For years, this scheme has been a moving target. The Government has extended, adjusted, and re-announced the threshold almost every Federal Budget since it began, leaving business owners unsure from one year to the next whether it would still apply.

The 2026-27 Federal Budget changed that. The Government announced the $20,000 threshold will become a permanent part of the tax system from 1 July 2026, rather than something renewed year by year. If you're planning purchases for this financial year, that's genuinely useful to know.

One thing worth flagging: as of mid-August 2026, this change still isn't law. The enabling legislation remains before the Senate, so the standing $1,000 threshold technically applies to assets first used or installed from 1 July 2026 until it passes. None of that affects your 2025-26 return, though. You can rely on the $20,000 threshold for any asset first used or installed by 30 June 2026 without needing to wait on Parliament.

Why this is worth a second set of eyes

Most mistakes with this scheme come down to timing and paperwork, not the purchase itself, and that's exactly the kind of detail that's easy to miss when you're running a business rather than chasing tax rules for a living.

Our team at Clarity Taxation looks at claims like this every EOFY, so we know which delivery dates and installation records the ATO wants to see, and where business owners typically slip up. We also keep track of what's confirmed law versus what's only been announced in the Budget, so you're never caught out either way.

It's the kind of check that takes us a few minutes and can save you from having to amend a return later.
