As the 2025–26 financial year approaches its end on 30 June 2026, many Australian business owners ask the same question: which capital purchases still make sense operationally—and which might also qualify for the instant asset write-off under ATO rules?
This guide explains how the concession works for the 2025–26 income year, why timing matters more than EOFY marketing, and how portable power can be one practical category within a broader EOFY equipment plan. It is general information only and does not constitute tax, legal, or financial advice.

Key Takeaways
● The Australian Taxation Office (ATO) allows eligible small businesses with an aggregated annual turnover of less than $10 million to access the instant asset write-off under simplified depreciation rules—when all conditions for the 2025–26 income year are met.
● The $20,000 threshold applies on a per-asset basis for 2025–26. You may be able to claim multiple eligible items in the same financial year, but each asset must independently satisfy eligibility, cost, timing, and exclusion rules—not one combined spending cap.
● You must have the asset first used or installed ready for use in your business on or before 30 June 2026 to claim it in the 2025–26 income year (subject to ATO rules).
● If you use an asset for both business and private purposes, you can generally only claim the business-use percentage of the cost.
● Investing in scalable, portable energy hardware can give mobile businesses reliable off-grid power while potentially forming part of an eligible EOFY equipment purchase—confirm deductibility with a registered tax agent.
Decoding the Instant Asset Write-Off ATO 2026 Rules
For the 2025–26 income year, the instant asset write-off sits within the ATO's simplified depreciation system. Where conditions are met, it may allow an immediate deduction for the business portion of an eligible asset's cost in the year the asset is first used or installed and ready for use—instead of spreading depreciation over several years.
The turnover threshold
To access the small business instant asset write-off, your enterprise must be carrying on a business with an aggregated annual turnover below $10 million, as defined by the ATO. Aggregated turnover can include your business's annual turnover plus income from affiliates and connected entities—not just your main entity.
Confirm how this applies to your structure with a registered tax agent before EOFY spending.
The per-asset advantage
For 2025–26, the ATO states a $20,000 limit per eligible asset (excluding GST if your business is registered for GST and claims input tax credits). That means you may be able to purchase multiple separate items—commercial tools, technology, vehicles (subject to other limits), or portable power stations—and treat each qualifying asset on its own, provided no single item costs $20,000 or more (for the relevant threshold) and each meets all other ATO conditions for that income year.
Important: This is not a blanket rule that "any number of sub-$20k items always qualify". Each asset must still pass turnover tests, simplified depreciation election, asset-type rules, timing, and record-keeping requirements for 2025–26.
Handling assets over $20,000
If essential machinery exceeds the threshold, it is generally allocated to the small business simplified depreciation pool rather than written off instantly. ATO pool guidance commonly cites 15% depreciation in the first income year the asset is used (or installed and ready for use) and 30% in later years—subject to current ATO rules and your adviser's calculations.
Do not confuse the instant asset write-off with temporary full expensing—they are separate measures with different eligibility and time frames. Ask your tax agent which rule applies to each planned purchase.
The Crucial "Ready for Use" Deadline
EOFY is a timing checkpoint, not a separate tax scheme. For 2025–26, the decisive question is often whether the asset is physically in use in your business before the year ends.
Physical operation
The ATO requires that you first use the asset, or install it ready for use, by 30 June 2026 for it to fall within the 2025–26 income year (subject to all other conditions). "Ready for use" means the asset can operate in your business—not merely sit in a box.
Shipping delays
Paying an invoice in late June is not enough. If supply-chain delays push delivery or commissioning into July 2026, you may need to defer the deduction to the 2026–27 income year—even if you paid before 30 June.
Strategic timing
Plan EOFY equipment purchases early enough for freight, installation, vehicle fit-out (for example, alternator chargers), and commissioning. Portable power stations used on site should ideally be running tools or office loads in the business before the cut-off, not only ordered.
Maximising Your Small Business Tax Deduction with Portable Power
Tradespeople, mobile food vendors, construction teams, and regional service operators often need consistent electricity where mains power is limited. A portable power station can replace or supplement noisy petrol generators and—when used primarily for business—may be treated as eligible depreciating plant or equipment, subject to ATO rules and your business-use apportionment.
Powering the jobsite — BLUETTI Elite 300 + Charger 2
Best for: Heavy-duty mobile crews running high-draw tools across multiple sites in a day.
| AU spec | Detail |
| Elite 300 | 3,014.4 Wh · 2,400 W continuous (4,800 W surge) · 26.3 kg · 2 × 230 V AC outlets |
| Charger 2 | Up to 1,200 W combined input (800 W alternator + 600 W solar max) |
The Elite 300 handles demanding trade loads when used intermittently—battery chargers, lighting, and many corded tools. Paired with Charger 2, crews can recharge while driving between jobs instead of idling a generator at every stop.
Entry-level mobile power — BLUETTI Elite 100 V2 + Charger 1
Best for: Sole traders, consultants, and light mobile operators needing reliable power for laptops, lighting, routers, and small equipment without a large footprint.
| AU spec | Detail |
| Elite 100 V2 | 1,024 Wh · 1,800 W continuous · 11.5 kg |
| Charger 1 | Up to 560 W alternator charging |
This combination keeps weight and capital cost lower while still supporting everyday mobile workflows. Confirm whether each item is a separate depreciating asset for your entity.
The portable middle ground — BLUETTI Elite 200 V2
Best for: Professionals who need substantial output in a still-portable form factor—mobile workshops, event setups, or mixed tool-and-IT loads.
| AU spec | Detail |
| Elite 200 V2 | 2,073.6 Wh · 2,600 W continuous (3,900 W lifting power) · 24.2 kg |
Sits between the compact Elite 100 V2 and the higher-capacity Elite 300 for operators who want more runtime without moving to a full site-office stack.
Understanding the limitations
The ATO requires strict apportionment. If you buy a BLUETTI power station for weekday tool use but take it family camping on weekends, you can generally only claim the business-use percentage—not the full purchase price.
The write-off also reduces taxable income; it does not automatically refund the full capital cost at purchase. You still need cash flow to buy the asset upfront.
Purchase AU-certified units (RCM compliance, local warranty) from BLUETTI Australia or authorised retailers—not grey-import US (120 V) models.

Strategic Planning for Your EOFY Equipment Purchases
A smart EOFY equipment purchase strategy is more than rushing to spend before 30 June.
1. Review operational bottlenecks — What failures, outages, or delays cost you money every week?
2. Prioritise the business case first — Buy because the upgrade improves safety, uptime, or revenue—not only because EOFY sales are live.
3. Talk to your tax agent early — Confirm aggregated turnover tests, simplified depreciation election, GST treatment, and business-use apportionment.
4. Order with lead time — Essential hardware such as a BLUETTI portable power station or Charger 2 fit-out should arrive and power your operations before 30 June 2026 if you intend to claim in 2025–26.
5. Keep records — Invoices, delivery dates, commissioning notes, and logbooks support business-use claims.
By planning capital expenditure now, you improve the chance that equipment is working in your business before the deadline, while your adviser confirms whether the instant asset write-off applies to each asset in 2025–26.
FAQ
What is the instant asset write-off 2026 Australia limit?
For the 2025–26 income year (financial year ending 30 June 2026), the ATO states a $20,000 threshold per eligible asset for businesses that meet simplified depreciation conditions and have an aggregated turnover under $10 million. The limit applies to each asset individually—not as a single cap on total EOFY spending. Confirm your eligibility with a registered tax agent.
How does the instant asset write-off ATO 2026 rule handle private use?
If you use an asset for both business and personal purposes, the ATO generally requires you to apportion the cost. You claim only the percentage that relates to business use, supported by records such as logbooks, job schedules, or usage diaries. This applies to portable power stations used on weekdays for work and on weekends for leisure.
Does an EOFY equipment purchase have to be delivered by 30 June?
To claim in the 2025–26 income year, the asset must generally be first used or installed and ready for use in your business on or before 30 June 2026—not only ordered or paid for. If you order in June but commission the asset in July, you may need to claim in the following financial year. Plan deliveries and set up accordingly.
