Most business owners treat expenses as something that happens to them. Invoices arrive, money leaves the account, and at some point in October the accountant sorts it out. The businesses that pay less tax do something different: they decide what they buy, and when they buy it, with the tax outcome already in view. The instant asset write off is the clearest example of how that works, because it lets an eligible small business deduct the full cost of an asset in the year it is first used rather than clawing it back a slice at a time over several years.

That single timing difference is worth real money to cash flow. It is also widely misunderstood, which is why plenty of businesses either miss claims they were entitled to or buy things they never needed. Here is how to use it deliberately.

Why Expense Timing Beats Expense Volume

Every dollar a business legitimately spends on running itself reduces taxable income. What separates a tax strategy from a shopping list is control over when the deduction lands and how much of it lands at once.

Buy a $9,000 piece of equipment without the concession and you depreciate it across its effective life, collecting the deduction in fragments over several years. Buy the same equipment as an eligible small business and you claim the lot this year. The total deduction is identical. The cash flow is not. Getting the money back now, while you are still paying off the asset, is the entire point.

Step 1: Understand What a Deduction Actually Saves You

This misunderstanding costs businesses the most, and it runs in both directions.

A deduction reduces your taxable income, not your tax bill. A company taxed at the 25% base rate entity company tax rate that claims $20,000 does not save $20,000. It saves roughly $5,000, and it has parted with $20,000 to get there. Anyone who tells you an asset is “basically free at tax time” is either confused or selling something.

Run it the other direction as well. If you genuinely need the equipment, the concession makes a purchase you were always going to make materially cheaper in the year you make it. The test is never “does it reduce my tax”. The test is “do I need this, and is now the right year to buy it”.

Step 2: Confirm You Qualify for the Instant Asset Write Off

Eligibility rests on three things, and all three have to hold.

• Aggregated turnover under $10 million. Aggregated turnover includes connected entities and affiliates, not just the trading company. Groups with multiple entities most often get this wrong.
• You apply the simplified depreciation rules. The write off sits inside that regime, so it is not available to a business using general depreciation.
• The asset costs less than the threshold, tested per asset. Not per invoice, not per supplier, and not in total for the year.

The threshold is $20,000. As part of the 2026-27 federal Budget handed down on 12 May 2026, the government moved to make that limit permanent from 1 July 2026 rather than extending it year by year, and the ATO’s new legislation guidance confirms the measure is now law. That is a meaningful change. For years this concession expired every 30 June and was renewed late, which made planning a guessing game. Permanence means you can build asset purchases into a multi-year plan instead of reacting to a Budget night announcement.

One caution worth keeping: “permanent” in tax means “until a future government changes it”. Check the current position before committing to a large purchase, and treat the review date at the top of this page as what it is.

Step 3: Check the Asset, Not Just the Price Tag

An asset under $20,000 is not automatically claimable. The ATO excludes several categories from the simplified depreciation rules entirely, including:

• Assets leased out, or expected to be leased out, for more than 50% of the time
• Assets used in research and development activities
• Capital works, including buildings and structural improvements
• Horticultural plants, including grapevines
• Software allocated to a software development pool

Two further points catch people out. If you are registered for GST, the $20,000 is measured GST exclusive, which quietly lifts your effective ceiling to about $22,000 on the shelf price. And second-hand assets are eligible, which matters a great deal for trades and construction businesses buying used plant and vehicles.

Vehicles have their own ceiling. For a passenger car first used or leased in the 2026-27 income year, depreciation is capped at the car limit of $69,883, regardless of what you paid. A one tonne ute or a van not designed principally to carry passengers generally falls outside the car limit, which is why the work ute and the company sedan are treated very differently.

Step 4: Get the Timing Right

The deduction is triggered when the asset is first used or installed ready for use, not when you order it, pay the deposit, or receive the invoice.

This is where good intentions fall over. A machine ordered on 20 June that arrives in the second week of July belongs to the following income year. If you are buying near the end of a financial year specifically to bring a deduction forward, the delivery and commissioning date is the date that counts, so confirm it in writing with the supplier before you sign.

The flip side is just as useful. If this year has been lean and next year looks stronger, deliberately landing an asset in the stronger year puts the deduction where it offsets more income. That is the difference between claiming an expense and planning one.

Step 5: Use the Small Business Pool for Anything Over the Line

An asset costing $20,000 or more is not lost. It goes into the small business pool, where you deduct 15% of its cost in the year it is allocated and 30% of the opening pool balance every year after that. Slower than an immediate write off, but considerably faster than the effective life method most businesses would otherwise use.

There is a quiet win here that gets missed: if the pool balance at the end of an income year is below the current threshold, before applying the 30% deduction, you can write off the entire remaining balance. Businesses that have run a pool for several years often find it has wound down far enough to clear out completely.

A worked example

Take a Gold Coast building company with turnover of $2.8 million. During the year it buys a laser level for $2,400, a site trailer for $8,900, a compressor for $4,600, three laptops at $2,100 each, and a second-hand work ute for $34,000.

Every item except the ute sits under $20,000 on its own, so each is written off immediately. That is $22,200 deducted this year, even though the combined figure is over the threshold, because the test applies asset by asset. The ute goes into the pool at 15%, adding a $5,100 deduction in year one and 30% of the declining balance after that.

At a 25% company tax rate, the $22,200 of immediate deductions reduces tax by roughly $5,550 this year. Useful, and worth planning for. Not, however, a reason to buy a compressor the business does not need. Figures are illustrative only and are used to show how the rules interact.

Step 6: Plan It, Do Not Panic at 30 June

The businesses that get the most out of this decide in February what they intend to buy by June, and check that decision against forecast profit rather than the bank balance. That means knowing roughly where your taxable income is landing before the year closes, which means your bookkeeping needs to be current rather than reconstructed in September.

A simple rhythm works: review asset replacement needs at the half year, model the tax effect against your forecast position, confirm delivery dates for anything you intend to claim this year, and keep the paperwork as you go. Purchase invoices, first use dates, business use percentages and payment evidence are what turn an intended claim into a defensible one. If your cash flow forecast shows the purchase is affordable and the numbers support the timing, you are making a business decision with a tax benefit attached. That is the right order.

Common Mistakes to Avoid

• Buying for the deduction. Spending a dollar to save 25 cents is a loss unless you needed the thing anyway.
• Adding up invoices instead of assets. The threshold is per asset. A $30,000 fit out made of eight separate assets may qualify in full, while one $21,000 machine does not.
• Forgetting aggregated turnover. Connected entities and affiliates count. Group structures are where eligibility quietly disappears.
• Assuming an ordered asset is a claimed asset. First used or installed ready for use is the only date that matters.
• Ignoring business use percentage. An asset used 60% for business gives you 60% of the deduction, not all of it.
• Overlooking the pool. Missing the threshold is not a dead end, and an unclaimed pool balance under the threshold is money left sitting.

Frequently Asked Questions

What is the instant asset write off threshold right now?

$20,000 per asset, for businesses with aggregated turnover under $10 million that use the simplified depreciation rules. The 2026-27 Budget moved to make the $20,000 limit permanent from 1 July 2026, and the ATO confirms the measure is now law. Because this threshold has changed frequently in the past, confirm the current figure on the ATO instant asset write off page before a major purchase.

How many assets can I claim in one year?

There is no cap. The threshold applies to each asset individually, so a business can write off many qualifying assets in the same income year provided each costs less than $20,000 and is first used or installed ready for use in that year.

Do second-hand assets qualify?

Yes. Used assets are treated the same way as new ones, subject to the same threshold, exclusions and business use rules. For trades, construction and manufacturing businesses buying used plant, this is often where the concession does the most work.

Is the $20,000 threshold GST inclusive or exclusive?

If you are registered for GST and can claim the GST credit, the threshold is measured on the GST exclusive cost. If you are not registered for GST, you measure it on the full amount you paid.

What happens if an asset costs more than $20,000?

It goes into the small business pool rather than being written off immediately. You deduct 15% of the cost in the first year and 30% of the opening balance each year after that. If the pool balance later falls below the threshold at year end, you can write off the whole remaining balance in that year.

Can I claim an asset I bought but have not started using?

No. The deduction depends on the asset being first used or installed ready for use within the income year. A purchase sitting in a supplier’s warehouse on 30 June belongs to the following year.

Next Steps

The instant asset write off is one concession among many, and on its own it is a tactic rather than a strategy. Used properly it sits inside a wider plan covering your business structure, how profits are drawn, when major purchases land, and what your forecast tax position looks like before the year ends.

Our business accountants work with owners across the Gold Coast and South East Queensland to plan asset purchases and tax positions ahead of time rather than reporting on them afterwards, including specialist support for building and construction businesses where plant and vehicle decisions move real money. If your company tax return is the first time each year you find out what you owe, there is a better way to run it.
