The short version
$20,000 per asset, for businesses with aggregated turnover under $10 million.
How the $20,000 instant asset write-off works from 1 July 2026, whether financed assets qualify, the installed-ready-for-use rule and how to time a purchase.
Every May and June, the same conversation happens in workshops and offices around the country: "should we buy that before 30 June for the tax?". The instant asset write-off is a genuinely useful tool for small businesses, and from 1 July 2026 its $20,000 threshold is permanent. But it's also widely misunderstood, especially when finance is involved. Here's what owners need to know.
This is general information, not tax advice. Your accountant should confirm how the rules apply to you.

The points that decide whether this suits your business.
$20,000 per asset, for businesses with aggregated turnover under $10 million.
Permanent from 1 July 2026.
The asset must be first used or installed ready for use in the income year.
According to the ATO:
Assets costing $20,000 or more go into the small business depreciation pool: 15 per cent in the first income year, 30 per cent each year after. If the pool balance is under $20,000 at the end of an income year, it can be written off too.
The deduction follows ownership, not how you paid.
Cash: Who owns it The business; Write-off generally available? Yes, if eligible
Business loan (unsecured or property-backed): Who owns it The business; Write-off generally available? Yes, if eligible
Chattel mortgage: Who owns it The business; Write-off generally available? Yes, if eligible
Finance lease or rental: Who owns it The financier; Write-off generally available? No: lease payments are treated differently
Hire purchase: Who owns it Depends on the arrangement; Write-off generally available? Ask your accountant
So a business can finance a $17,000 asset, own it from day one, and still claim the full write-off in that year, while also generally deducting interest on the loan as it's paid. For more on the different structures, see asset finance explained.

This is where June purchases go wrong. The write-off applies in the year the asset is first used or installed ready for use, not the year you ordered or paid for it.
If you're buying close to 30 June, check lead times and installation dates with the supplier before relying on the deduction.
Less than many people think. A deduction reduces taxable income; it doesn't refund the purchase.
Illustrative example. A Toowoomba farm contracting business buys a $16,000 slasher for its tractor in May. If its marginal tax rate is 25 per cent, writing the slasher off in full reduces tax by around $4,000 in that year. The business is still $12,000 out of pocket. If the slasher earns its keep through extra paddock work, that's a good purchase with a timing bonus. If it was only bought for the deduction, the business has spent $12,000 on something it didn't need.
The real question is always whether the purchase pays for itself. The tax timing is a bonus on top. Our purchase payback calculator shows how quickly a purchase earns back its cost.
For the right purchase, they combine well:
That can leave a business with better cash flow in year one than paying cash. But don't stretch the finance longer than the asset's useful life just to keep repayments down. Our guide to buying outright or financing covers that balance.
Larger items, like most new utes, trucks, heavy machinery and fit-outs, usually exceed the threshold and are depreciated.
A short conversation in April or May can save a lot of June stress. Questions worth asking:
Your accountant can also tell you whether the simplified depreciation rules are the best choice for your business overall. It's general guidance from us; the specifics belong with them.
Whatever you buy, keep the tax invoice, proof of delivery and a note of the date the asset was first used or installed ready for use. For installed equipment, the installer's completion certificate or job sheet is useful evidence. If you finance the purchase, keep the loan contract too, since your accountant will need it to separate interest from principal. Good records make tax time faster and give you a clear answer if the ATO ever asks about the timing of a claim.
If the purchase makes sense on its own, finance can let you get it working and keep your cash for the new financial year. Asking us won't put anything on your credit file; a check is only discussed once you decide to go ahead. We don't fire your enquiry off to a list of lenders. A real person looks at the purchase and the timing, and calls you with options.
Please be accurate about what you're buying, the cost and when you need it installed, so we can work to your deadline. Start your enquiry.
Loanster keeps the enquiry process straightforward: no credit check to enquire, a real person looks at your situation, and your details are not sprayed out to a pile of lenders.
Personal details are submitted through a secure form and are not sent through URL query strings.
Enquiries can include ABN, BAS, ATO, bank statement and asset details where relevant.
Approval, pricing, loan amounts and funding times depend on lender assessment.
Loanster helps identify what information may be needed before a lender can make a decision.
Generally yes, if the business owns the asset, such as through a business loan or a chattel mortgage, and it meets the other conditions. Under a lease or rental, the financier owns the asset, so the treatment is different. Confirm with your accountant.
Per asset. A business can write off several eligible assets in a year as long as each one costs less than $20,000. Be careful with items that are really one asset split across invoices.
Only if the asset is first used or installed ready for use by 30 June. An order placed but not delivered, or delivered but not installed, generally doesn't count for that year.
For small businesses using simplified depreciation, they go into the small business pool, which is depreciated at 15 per cent in the first income year and 30 per cent in later years. If the pool balance falls below $20,000 at year end, it can be written off.
No. A deduction reduces tax on money you've spent; it doesn't give the money back. A $15,000 purchase might save a few thousand dollars in tax, but you're still out the rest. Only buy what earns its keep.
