Instant Asset Write-Off 2026: The Complete Guide for Australian Small Business

What Is the Instant Asset Write-Off

The instant asset write-off lets eligible small businesses immediately deduct the full cost of a qualifying business asset in the year it is first used or installed ready for use, rather than depreciating it over several years. For a profitable small business, this can deliver a same-year tax saving worth thousands of dollars on capital purchases that would otherwise reduce taxable income only gradually.

The concession has been around in some form since 2015, but the threshold and eligibility rules have changed almost every year. The federal government uses it as a small business stimulus lever, raising the cap during downturns and lowering it during budget repair phases. That instability is precisely why so many small business owners are confused about what they can claim, when, and on what.

This guide covers the rules as they apply in the 2025-26 financial year, with a clear view of how they intersect with Xero, your BAS, and your year-end tax return.

The Current Threshold for FY26

For the 2025-26 financial year, the instant asset write-off threshold is $20,000 per asset for eligible small businesses with aggregated annual turnover under $10 million.

This is the same threshold that applied in FY25, after the FY26 extension was confirmed in the federal budget. It applies to assets first used or installed ready for use between 1 July 2025 and 30 June 2026.

Key points to lock in:

• The $20,000 cap is per asset, not total spend. You can write off multiple assets in the same year provided each one is under the cap.
• The cap applies GST-exclusive if you are registered for GST.
• An asset costing more than $20,000 cannot be partially written off under this concession. It moves into the general small business depreciation pool and depreciates at 15% in year one and 30% thereafter.
• The asset must be first used or installed ready for use by 30 June 2026 to be claimed in the FY26 return. Ordered and unpaid does not count. Paid and not yet delivered does not count.

Who Is Eligible

To claim the instant asset write-off in FY26 you must:

1. Be carrying on a business (so you have an active ABN and trading activity, not just an investment portfolio)
2. Have aggregated turnover under $10 million for the income year
3. Choose to use the simplified depreciation rules in Subdivision 328-D of the ITAA 1997
4. Use the asset for taxable business purposes (private use is excluded proportionally)

Aggregated turnover includes connected entities and affiliates, not just your own ABN. If you operate through several related companies or trusts, you need to add them up to test eligibility. This catches a lot of growing small businesses by surprise.

Sole traders, partnerships, companies, and trusts can all qualify, provided the turnover and trading tests are met.

What You Can and Cannot Claim

Assets That Qualify

Almost any depreciating business asset under $20,000 GST-exclusive qualifies, including:

• Tools and trade equipment
• Office furniture, fit-out, and partitioning
• Computers, monitors, printers, and tablets
• Phones and mobile devices
• Point of sale terminals and kitchen equipment
• Tradie utes and light commercial vehicles (subject to the car limit for passenger vehicles)
• Workshop machinery, compressors, generators
• Coffee machines, refrigeration, ovens
• Salon chairs, treatment beds, dental equipment
• Photography and video equipment
• Inventory racking, shelving, and forklifts under the cap

Assets That Do Not Qualify

• Capital works such as building extensions, renovations, structural improvements, and most fit-out elements that become part of the building fabric (these fall under Division 43 building write-off rules)
• Trading stock and inventory (these are deducted as cost of goods sold, not depreciated)
• Software developed in-house (different rules apply)
• Horticultural plants and certain primary production assets (separate concessions exist)
• Assets that have been previously held by you or an associate (anti-avoidance rules)

The Car Limit Trap

If you buy a passenger vehicle (designed to carry fewer than nine passengers and less than one tonne payload), the depreciable cost is capped at the car limit, which for FY26 is $69,674. This cap exists separately from the instant asset write-off threshold.

In practice, since the car limit is well above the $20,000 instant write-off cap, any passenger car you buy will be over the threshold and will go into the small business pool rather than being instantly written off. Most utes used by trades qualify as one-tonne commercial vehicles and avoid the car limit, but always check the GVM of the specific model before buying.

How to Plan Around the Threshold

The instant asset write-off is most powerful when you plan your capital spending around the financial year. Three practical strategies:

Strategy 1: Bring Forward Necessary Purchases Before 30 June

If you were going to buy a new laptop, a piece of trade equipment, or a workshop tool anyway, and your business is profitable this year, buying before 30 June 2026 accelerates the deduction by twelve months. The asset must be installed ready for use by 30 June, not just paid for.

Strategy 2: Stay Under the Cap Where Possible

If you are looking at a $22,000 item, ask whether a $19,500 equivalent meets the need. The full instant deduction often outweighs the modest spec upgrade.

Strategy 3: Sequence Purchases Across Financial Years

If you have multiple capital purchases planned and your cash flow allows flexibility, consider whether spreading them across two financial years gives you a better marginal tax outcome. A loss in one year is not as valuable as offsetting profit, so the goal is to land the deduction where it offsets the most income at the highest marginal rate.

How to Handle the Instant Asset Write-Off in Xero

Xero does not have a specific instant asset write-off button. The mechanics live in your fixed asset register and your tax return preparation. Here is the clean workflow:

Step 1: Code the Purchase Correctly

When you receive the bill or process the bank feed transaction, code the asset to your Fixed Asset account in the chart of accounts, not to a P&L expense account. This keeps the balance sheet clean and makes year-end reconciliation easier.

Step 2: Register the Asset

In Xero, go to Accounting > Fixed Assets. Click New Asset and enter the purchase price, purchase date, asset type, and depreciation method. For instant asset write-off candidates, set the depreciation method to Full Depreciation at Purchase.

Step 3: Run the Depreciation

Once your accountant or BAS agent confirms the asset qualifies for the instant write-off, run depreciation in Xero. The asset will be fully depreciated in the period of purchase, reducing the net book value to zero.

Step 4: Document for the Tax Return

Your tax agent will use the Xero fixed asset register to prepare your tax return. The instant asset write-off appears in the small business depreciation labels on the return, not as a separate line. Make sure the asset register reconciles to your balance sheet before tax time.

Step 5: Keep Supporting Records

Keep the supplier invoice, proof of payment, and evidence the asset was installed ready for use by 30 June. The ATO does audit small business depreciation claims, particularly large clusters of write-offs in the final weeks of June.

Common Mistakes to Avoid

• Confusing the threshold with previous years: The cap has been $1,000, $20,000, $25,000, $30,000, $150,000, and unlimited (under temporary full expensing) at various points. Always work to the current year rules.
• Forgetting the GST treatment: The $20,000 cap is GST-exclusive if you are registered. A $21,500 invoice that is $19,545 GST-exclusive still qualifies.
• Claiming on assets not installed ready for use: Paid and waiting on delivery is not enough. The asset must be in your business and capable of being used by 30 June.
• Mixing up private use: A laptop used 70% for business and 30% personally has only 70% of its cost eligible for the write-off.
• Forgetting the aggregated turnover test: Connected entities count, so growing groups can fall out of eligibility without realising.
• Buying for the sake of the deduction: A $20,000 deduction at 25% company tax saves you $5,000 in tax. You still spent $15,000 of real cash. Only buy what you actually need.
