Four Myths About the $20,000 Instant Asset Write-Off, and What the Law Actually Says

The $20,000 instant asset write-off is one of the most misreported numbers in Australian small business tax right now. Half the sites calling it permanent are wrong. As at July 2026 it is not law: it was announced in the 2026-27 Budget, the enabling Bill (Treasury Laws Amendment (Tax Reform No. 2) Bill 2026, Schedule 2) is still before Parliament, and the legislated default threshold from 1 July 2026 is $1,000. The $20,000 figure was law for the 2025-26 year only. Here are the 4 misconceptions we see most, and what the law actually says.

Myth 1: the $20,000 write-off is permanent and locked in

It is not law yet, and treating it as settled is the expensive version of this mistake. The government announced in the 2026-27 Budget that it would make the $20,000 threshold permanent from 1 July 2026. Announced is not enacted. The measure sits in the Treasury Laws Amendment (Tax Reform No. 2) Bill 2026, which was still moving through Parliament as at July 2026. Until it passes, the threshold actually in the law from 1 July 2026 is $1,000, the figure it reverts to each year absent an extension. The $20,000 threshold you may have used last year was real, but it was legislated for 2025-26 only. If you are planning a 2026-27 purchase around $20,000, the honest position is likely but not guaranteed, so check the ATO’s page before you commit.

Four common misconceptions about the instant asset write-off, set against what the law says.

Myth 2: the new $1,000 instant deduction is the same thing

Two different rules got jammed together in a lot of the coverage, and they are not the same. The 2026-27 Budget also introduced a $1,000 instant work-related deduction. That one is law, under the Tax Reform No. 1 Act 2026, and it lets employees and sole traders claim up to $1,000 of work-related expenses without receipts from 2026-27. The instant asset write-off is a different animal: a business deduction for the cost of a depreciating asset, under the simplified depreciation rules, for businesses with aggregated turnover under $10 million. Different taxpayers, different mechanism, different cap. If a source is using the confirmed $1,000 work-related deduction to argue the $20,000 asset write-off is now law, it has merged two measures that live in separate Bills.

Myth 3: buy it before 30 June and you have the deduction

Buying is not the test. Using is. To claim the write-off in an income year the asset has to be first used, or installed ready for use, in that year. Paying the invoice, placing the order, or having the thing sitting in a box on the loading dock at 30 June does not get you there. The classic example is the coffee machine delivered and running on 28 June, which qualifies, against the same machine still boxed on 30 June, which does not. If you are timing an end of year purchase, work backwards from delivery and install lead times, not from the payment date, and keep the records that prove the install date.

Myth 4: if it costs more than the threshold, you get nothing

You do not lose the deduction, you spread it. An asset that costs at or above the threshold goes into the small business pool, where it depreciates at 15% in the first year and 30% each year after (sections 328-185 and 328-190 of the ITAA 1997). Better still, if the whole pool balance falls under the threshold at the end of a year, you can write the entire balance off then (section 328-210). And the 5 year lockout that normally stops you re-entering the simplified rules after opting out is suspended until 30 June 2027. So a $25,000 machine is not a dead loss for deductions, it is a pooled one. Whether to pool it or handle it another way is the real write it off now or depreciate it question.

So where does that leave you

The through line is simple. The $20,000 figure is genuinely useful, and it may well become permanent, but as at July 2026 the number locked in the law from 1 July is $1,000. Plan on what is enacted, treat the permanent extension as likely, and confirm the status on the ATO’s page before you make a call that depends on it. While you are at it, the write-off is only one of the small business deductions worth getting right. If you would rather have the thresholds, the timing rules and the pool maths handled as you go, that is what Tax Assistant is built for.

The detail (current as at July 2026)

Instant asset write-off threshold: legislated default $1,000 from 1 July 2026. The $20,000 threshold for 2025-26 is law under the Treasury Laws Amendment (Strengthening Financial Systems and Other Measures) Act 2025. The permanent $20,000 measure from 1 July 2026 is in the Treasury Laws Amendment (Tax Reform No. 2) Bill 2026 (Schedule 2), not yet law as at July 2026. Confirm current status on the ATO instant asset write-off page.

Eligibility: a small business with aggregated turnover under $10 million using the simplified depreciation rules; the asset first used or installed ready for use in the income year; the threshold applies per asset, on the GST-exclusive cost if registered for GST. Cars are subject to the car limit ($69,883 for 2026-27).

Assets at or above the threshold: added to the small business pool, depreciated at 15% in the first year and 30% thereafter (ITAA 1997 ss 328-185, 328-190). A pool balance under the threshold at year end may be written off in full (s 328-210). The 5 year lockout on re-entering simplified depreciation (s 328-175) is suspended to 30 June 2027.

$1,000 instant work-related deduction: a separate measure, law under the Tax Reform No. 1 Act 2026 (Schedule 4), for employees and sole traders from 2026-27, claimable without receipts. It is not the instant asset write-off.

Company loss carry-back for entities under $1 billion: also in the Tax Reform No. 2 Bill 2026, from 1 July 2026, not yet law.
