The instant asset write-off allows eligible Australian businesses to immediately deduct the cost of qualifying assets in the income year the asset is first used or installed ready for use, rather than depreciating it over several years. Eligibility rules, thresholds, and the assets covered can change with each Federal Budget and legislative update, so speaking with a registered tax practitioner before lodging is strongly recommended.

What is the instant asset write-off?
The instant asset write-off (IAWO) is a federal tax concession that lets eligible businesses claim an immediate deduction for the cost of a depreciable asset, rather than spreading that deduction across the asset's effective life under normal depreciation rules. The policy intent is to encourage capital investment and improve cash flow for businesses.
The concession is administered by the Australian Taxation Office (ATO) and sits within Australia's broader simplified depreciation rules. It is distinct from temporary full expensing, which applied for earlier income years, and from standard small business depreciation pooling. Each of these mechanisms has different conditions, so it is important not to conflate them when planning.
For the 2025–26 income year, the operative rules are set out in the *Income Tax Assessment Act 1997* and any applicable legislative amendments. You can review the consolidated legislation at AustLII. Because thresholds and eligibility criteria are subject to ongoing legislative change, always cross-reference the ATO's current guidance rather than relying on figures published in prior years.

Who is eligible?
Eligibility for the instant asset write-off depends primarily on your business's aggregated annual turnover and whether you are operating as a business entity for tax purposes. The ATO sets out the specific turnover thresholds and entity types that qualify for each income year on its website — visit the ATO's page on small business tax concessions for the current criteria.
Generally speaking, sole traders, partnerships, companies, and trusts operating a business may be eligible, provided their aggregated turnover falls within the relevant threshold. "Aggregated turnover" includes not just your own business's annual turnover but also the turnover of any associated or connected entities, which can be a surprise for business owners who assumed they qualified because their own revenue was modest.
It is also worth noting that the write-off applies per asset, not as an unlimited total deduction. If an asset's cost exceeds the applicable threshold for your turnover category, the excess amount cannot be immediately deducted and must instead be depreciated through the small business pool or under standard depreciation rules. A qualified accountant can help you model which approach is most advantageous given your particular circumstances.

What assets qualify?
Not every purchase your business makes will qualify for the instant asset write-off. To be eligible, the asset generally must be:
- A depreciable asset (also called a "depreciating asset" under tax law) - Used or installed ready for use in the relevant income year - Used for a taxable purpose -- that is, for producing assessable income - Under the applicable cost threshold for your turnover category
Common examples of qualifying assets include machinery, vehicles, tools, office equipment, and certain fit-out costs. However, some assets are specifically excluded by legislation, including assets that are not used in Australia, trading stock, and assets leased to another party under certain arrangements. Land and certain intangible assets are also generally outside the scope of the write-off.
If an asset is used partly for private purposes, only the business-use proportion of the cost is deductible. Keeping accurate records of usage is therefore essential, particularly for vehicles and home-based equipment. The ATO has detailed guidance on record-keeping obligations at ato.gov.au.

How do thresholds work in practice?
The threshold that applies to your business depends on the income year in question, your aggregated annual turnover, and the legislative settings in place at the time of purchase and first use. Because these settings can be amended by Parliament, the threshold applicable for 2025–26 may differ from what applied in earlier years.
Rather than stating a specific dollar figure here without an attached authoritative source for the 2026 period, we strongly encourage you to consult the ATO's dedicated instant asset write-off resource at ato.gov.au and any relevant Treasury announcements at treasury.gov.au. These sources are updated when legislative changes pass and provide the most reliable figures for planning purposes.
Your accountant can also help you determine whether a proposed asset purchase falls inside or outside the current threshold -- and whether there are timing strategies, such as purchasing before or after 30 June, that could affect which rules apply.

Common mistakes to avoid
Several recurring errors arise when businesses attempt to claim the instant asset write-off without professional guidance.
Misidentifying the income year. The write-off applies to the year the asset is first used or installed ready for use -- not necessarily the year of purchase or the year the invoice is paid. Ordering equipment in May but not receiving it until July, for example, moves the deduction into the following income year. Overlooking aggregated turnover. As noted above, connected entities count towards your aggregated turnover. Business owners who operate multiple entities or have associates with businesses may inadvertently exceed a threshold they believed they were well under. Assuming all business purchases qualify. Repairs, consumables, and certain software licences may not be depreciating assets at all, meaning the write-off simply does not apply to them. Always confirm the tax treatment of each item separately. Not retaining supporting records. The ATO can request evidence that an asset was purchased, used for a business purpose, and within the eligible threshold. Invoices, delivery records, and asset registers are the foundation of a defensible claim.---
How an accountant can help
Navigating the interaction between the instant asset write-off, small business pooling, and standard depreciation rules is genuinely complex. A registered tax agent or BAS agent can help you:
- Confirm your eligibility based on current aggregated turnover calculations - Identify which of your planned or recent purchases qualify - Time asset purchases strategically around the end of the financial year - Prepare and lodge accurate tax returns and schedules - Respond to any ATO queries about depreciation claims
To verify that any practitioner you engage is registered, use the Tax Practitioners Board public register. Registration is a legal requirement for anyone charging a fee to prepare or lodge tax returns in Australia.

Interaction with other tax concessions
The instant asset write-off does not operate in isolation. Depending on your circumstances, it may interact with:
- Small business pooling, where assets below the threshold are immediately deducted but assets above it enter a pool depreciated at a set rate - Research and development (R&D) tax incentives, which have their own cost-allocation rules that may affect whether an asset's full cost is available for the write-off - GST input tax credits, where the relevant cost of an asset for depreciation purposes may be the GST-exclusive amount if you are registered for GST
Company and trust structures may also have different considerations compared with sole traders, particularly where the asset is used across multiple entities. For businesses with more complex structures, advice from both a registered tax agent and, where relevant, a professional familiar with corporate law or SMSF rules (see ASIC's guidance) is advisable.

FAQ
Q: Can I claim the instant asset write-off for a second-hand asset? A: Whether second-hand assets qualify depends on the specific rules in place for the relevant income year and your business's turnover category. The ATO's current guidance should be your first reference point, and a registered tax agent can advise based on your specific situation. Q: Does the write-off apply to assets purchased on finance? A: Assets acquired under certain finance arrangements may still be eligible, but the treatment depends on how the arrangement is structured -- for example, whether it is a chattel mortgage, finance lease, or hire purchase. The tax and accounting treatment differs across these structures, making professional advice particularly important. Q: What happens if my asset cost exceeds the threshold? A: The excess amount that cannot be immediately deducted must generally be allocated to a small business depreciation pool or depreciated under standard rules over the asset's effective life. Your accountant can help you understand the most tax-effective approach. Q: I operate multiple businesses -- how does that affect my eligibility? A: Aggregated turnover includes the turnover of connected and affiliated entities, meaning you may have a higher aggregated turnover than any single business suggests. This is one of the most commonly misunderstood aspects of the concession and is a strong reason to seek professional advice before assuming eligibility.---
