Australia's construction and trades sector continues to thrive, but the complexity of tax rules often catches tradies off guard. One of the most valuable tax concessions available to small and medium-sized building businesses is the instant asset write-off, yet many tradies are still unaware of how it works or when they need to act to capture the benefit.
In our experience advising Melbourne tradies and builders, the difference between a structured, timely approach to asset purchases and a reactive one can mean $5,000 to $20,000 in tax savings within a single financial year. The instant asset write-off threshold is higher in 2025-26 than it will be from 2026-27 onwards, which creates a genuine window of opportunity.
This guide explains the $20,000 instant asset write-off threshold for 2025-26, which assets qualify, how to calculate the benefit for vehicles, and the strategic timing decisions you need to make before 30 June 2026. Whether you're planning to purchase a new ute, upgrade your power tools, or invest in site equipment, understanding these rules ensures you capture every dollar of deduction you're entitled to.
Our builders and tradies accounting team in Melbourne can help you implement a tax-efficient asset purchase strategy aligned with your business growth plans.
Threshold: $20,000 per asset. Applies to businesses with aggregated annual turnover under $10 million. Deadline: assets must be first used or installed ready for use by 30 June 2026. GST-exclusive cost is used to determine eligibility.
The instant asset write-off allows eligible small businesses to claim a full deduction for a single asset in the year it is acquired and used in the business, rather than deprecating it over several years. This is a significant cash flow advantage, particularly for tradies investing in equipment.
To qualify for the instant asset write-off, your business must meet all of these conditions: you are a small business entity (aggregated annual turnover under $10 million), the asset costs less than $20,000 (GST-exclusive if you're registered for GST), the asset is first used or installed ready for use before 30 June 2026.
If your business turnover exceeds $10 million, you lose access to this concession entirely and revert to standard depreciation rules. Similarly, the asset must be a depreciating asset used in the business. The key date is when you first use the asset in your business, not when you purchase it. If you purchase an asset in June 2026 but don't use it until July, you don't qualify for the instant asset write-off.
The $20,000 limit is based on the GST-exclusive cost of the asset. If you're registered for GST and purchase an asset for $22,000 including GST, the GST-exclusive cost is approximately $20,000, so it qualifies. If you're not registered for GST, the full purchase price is used. This distinction is important when calculating whether an asset falls within the threshold.
For full details on eligibility and the rules, consult the ATO's instant asset write-off page.
Power tools, hand tools, utes, trailers, site equipment, laptops, safety gear. Assets must be new, used in the business, and directly support your trade or building operations. Building improvements, structural changes, and assets over $20K do not qualify.
The instant asset write-off applies to most tangible assets, but not all. Understanding what qualifies and what doesn't helps you plan your purchases strategically.
Common tradie and builder assets that qualify include: power tools and hand tools (drills, saws, compressors, nail guns, grinders), utes and work vans (provided they cost under $20,000), trailers and site equipment (scaffolding, concrete mixers, generators, compressors), laptops and tablets used for the business, safety equipment (first aid kits, personal protective equipment lockers, safety signage), and plant and machinery used directly in your trade.
The key test is whether the asset is used to produce income and is of a business nature. If you purchase a tool that has dual personal and professional use, the asset may still qualify, but you can only claim the proportion relating to the business.
Building improvements and structural assets do not qualify. If you renovate an office, install permanent fixtures, or make structural changes to a building, these are treated as capital improvements and must be depreciated or written off under different rules. Similarly, land, buildings, and plant that becomes fixed to real property (such as permanent structures) fall outside the instant asset write-off scheme.
Assets costing more than $20,000 (GST-exclusive) also do not qualify. If you purchase a ute for $25,000 or a piece of machinery for $30,000, you cannot claim the full amount as an instant write-off. Instead, you depreciate the asset over its effective life using the diminishing value or prime cost method.
Both new and second-hand assets are eligible for the instant asset write-off, provided they meet the other conditions (cost under $20,000 GST-exclusive and first used or installed ready for use before 30 June 2026).
| Asset Type | GST-Exclusive Cost Limit | Qualifies? |
|---|---|---|
| Power drill | Under $20,000 | Yes |
| New ute | Under $20,000 | Yes |
| Concrete mixer | Under $20,000 | Yes |
| Scaffolding | Under $20,000 | Yes |
| Laptop for business | Under $20,000 | Yes |
| Office renovation | Any amount | No |
| Second-hand ute | Under $20,000 | Yes |
| New ute over $20K | Over $20,000 | No |

GST-exclusive cost is used. Business-use percentage applies for mixed-use vehicles. Car cost limit is $69,674 (2025-26). Full cost can be deducted if under $20K and first used before 30 June 2026.
Calculating the instant asset write-off for a ute or vehicle involves several steps. It's not as simple as taking the invoice price; you need to account for GST and business-use percentage.
Step 1: Determine the GST-exclusive cost. If you purchase a new ute for $22,000 inclusive of GST, the GST-exclusive cost is $22,000 divided by 1.1, which equals $20,000. This ute qualifies for the instant asset write-off.
Step 2: Apply the business-use percentage. If you use the ute for work 85% of the time and personally 15% of the time, you can only claim the business-use portion. Deductible amount: $20,000 x 85% = $17,000.
Step 3: Apply the car cost limit if applicable. The car cost limit ($69,674 for 2025-26) applies only to vehicles that meet the tax definition of a 'car' — a vehicle designed mainly to carry passengers with a load capacity under one tonne and fewer than nine passengers. Many commercial utes used by tradies are designed primarily to carry goods and have a load capacity of one tonne or more, which means they fall outside the 'car' definition and the car cost limit does not apply to them. If your vehicle is classified as a car under this definition, the car cost limit caps the amount you can depreciate. Check the vehicle's specifications or consult your tax adviser to confirm.
Step 4: Claim the deduction. You can now claim the $17,000 as an instant asset write-off in the 2025-26 financial year. Enter it on your tax return in the deductions section for plant and equipment. Keep the purchase invoice, proof of first use, and documentation of business-use percentage (such as a logbook if you've completed one).
The car cost limit is $69,674 for the 2025-26 financial year and applies only to vehicles that meet the tax definition of a 'car' — designed mainly to carry passengers, with a load capacity under one tonne and fewer than nine passengers. Many commercial utes and vans used by tradies have a load capacity of one tonne or more and are not classified as cars, so the car cost limit does not apply to them. If your vehicle is classified as a car, only $69,674 (or the business-use percentage of $69,674) can be deducted. This limit is indexed annually. Check the vehicle’s gross vehicle mass and payload specifications to confirm whether the limit applies.

The instant asset write-off threshold is time-sensitive. The $20,000 threshold applies only to assets first used before 30 June 2026. From 1 July 2026, the threshold is scheduled to revert to $1,000 (unless Parliament legislates a further extension). This creates a strategic window for tradies considering major equipment or vehicle purchases.
Timing decisions involve cash flow, financing options, business needs, and tax planning. Here's what to consider:
The tax benefit of timing a $15,000 to $20,000 asset purchase before 30 June 2026 rather than after is substantial. For a tradie on a 39% marginal tax rate (including Medicare Levy), a $19,000 deduction saves $7,410 in tax. This is real money that flows directly to your bottom line.

Contact Us Today →Under current legislation, the threshold is scheduled to revert to $1,000 from 1 July 2026 unless further extended. For small businesses using the simplified depreciation rules, assets costing $1,000 or more will be added to the small business general pool and depreciated at 15% in the first year and 30% in subsequent years. Businesses not using simplified depreciation rules depreciate assets over their effective life using general depreciation methods.
The $20,000 instant asset write-off is not permanent. Unless extended by Parliament (which happens from time to time), the threshold is scheduled to revert to $1,000 (unless Parliament legislates a further extension) from 1 July 2026. This fundamentally changes how you claim deductions for eligible assets.
From 1 July 2026, if you are a small business using the simplified depreciation rules and you purchase assets costing $1,000 or more, these assets are added to the small business general pool. The pool is depreciated at 15% in the first year and 30% in subsequent years. Businesses not using the simplified depreciation rules depreciate assets over their effective life using the general depreciation methods instead.
For example, if you purchase a $15,000 tool in July 2026, under the simplified depreciation rules, you claim 15% of $15,000 ($2,250) in the general pool in 2026-27. In 2027-28, you claim 30% of the remaining pool balance. This continues each year under the pool rules.
Assets under $1,000 continue to be claimed in full as immediate deductions (as they have been historically). Assets costing more than $20,000 (for small businesses using simplified depreciation) are also added to the general pool and depreciated at the same rates.
The change from instant write-off to depreciation reduces your immediate tax benefit. A $15,000 asset that could be deducted in full in 2025-26 will only yield a $2,250 deduction in 2026-27 (and smaller deductions in subsequent years). This is why timing your purchases before 30 June 2026 is strategically important.
If your business operates in the long term, the total deduction will be the same (the full cost is eventually claimed). However, the timing of the deduction matters for cash flow. A deduction taken immediately improves your tax position and cash flow in that financial year. A deduction spread over multiple years delays the benefit.
For detailed information on the depreciation rules, consult the ATO's small business depreciation pool page.
The ATO will challenge claims that lack supporting documentation. Keeping comprehensive records is not optional; it's essential to substantiate your deductions and protect yourself in an audit.
The ATO accepts digital records. Photograph receipts and invoices, store them in a cloud service like Dropbox or Google Drive, and organise them by asset type and financial year. The ATO's myDeductions app allows you to upload and store receipts directly. Digital records are as valid as physical ones, provided they're clear and legible.
Retention period: keep all records for a minimum of five years from the date of claim. If the ATO raises an enquiry, you need the documentation to substantiate your deduction.
For comprehensive guidance on what to keep and how long, refer to the ATO's record-keeping guidance page.
Our team at small business tax compliance Melbourne can help you set up a record-keeping system that ensures you're always audit-ready.

The instant asset write-off limit is $20,000 (GST-exclusive) for assets first used before 30 June 2026. This applies to single assets only; the $20,000 limit is per asset, not a total cap. For example, you can purchase ten assets at $19,000 each and claim each one under the instant asset write-off. From 1 July 2026, the threshold is scheduled to revert to $1,000 (unless Parliament legislates a further extension).
Yes, provided the ute costs less than $20,000 (GST-exclusive), is first used before 30 June 2026. However, if the ute is used for both business and private purposes, you can only claim the business-use percentage. For example, if a ute costing $18,000 is used 80% for work and 20% personally, you can only claim $14,400 ($18,000 x 80%) under the instant asset write-off. Also, if the ute costs more than $20,000, you cannot use the instant asset write-off and must depreciate it instead.
No. The $20,000 threshold is based on the GST-exclusive cost of the asset. If you're registered for GST and purchase an asset for $22,000 including GST, the GST-exclusive cost is approximately $20,000, so it qualifies for the instant asset write-off. If you're not registered for GST, the full purchase price is considered. GST is claimed separately through your GST return if you're a registered business.
You cannot claim the instant asset write-off for assets costing more than $20,000 (GST-exclusive). Instead, you must depreciate the asset. Small businesses using the simplified depreciation rules add the asset to their general small business pool, which is depreciated at 15% in the first year and 30% in subsequent years. Businesses not using simplified depreciation rules depreciate the asset over its effective life. For example, a $25,000 ute purchased in 2025-26 by a small business using the simplified rules would be depreciated at 15% ($3,750) in the first year, then 30% of the remaining pool balance in subsequent years.
No. The $20,000 threshold is time-limited and is set to expire on 30 June 2026. From 1 July 2026, the threshold is scheduled to revert to $1,000 under current legislation unless extended by Parliament. Parliament has extended the scheme previously, so it's possible that further extensions may be announced. However, you should not rely on this. The key message is: if you're planning to purchase eligible assets, do so before 30 June 2026 to capture the $20,000 threshold.
