Plan the commercial need, delivery date, evidence and finance structure before modelling any tax result. A deduction should never be the reason to buy an asset the business does not need.
The Australian financial year runs from July 1 to June 30. Any tax deductions — depreciation, instant asset write-off, interest — must relate to assets that are installed ready for use or first used for a taxable purpose by June 30 to be claimed in that financial year.
Timing can affect when eligible depreciation, interest and GST credits are recognised, but settlement before 30 June does not by itself guarantee a deduction. Before ordering a truck, excavator, ute or equipment item:
The enacted $20,000 extension ended on 30 June 2026. A proposal to make a less-than-$20,000 setting permanent was still before Parliament when this page was checked on 9 August 2026. A proposal is not an entitlement.
Prepare the supplier quote, delivery evidence, financials and structure comparison early. Finance timing depends on lender, asset, seller and document checks.
Start an Enquiry →If an immediate write-off is unavailable, ordinary or simplified depreciation may still apply. The correct method depends on the entity, election, asset and current law.
An eligible small business using simplified depreciation may add qualifying assets to a general pool. Confirm the current rates, taxable-purpose percentage and pool treatment with the accountant before putting a benefit in the acquisition case.
Under ordinary depreciation, timing and effective life affect the first-year amount. A late purchase can produce only a small current-year deduction, so compare the operational value of buying now with the full cash and financing cost.
| Structure | Depreciation? | Why |
|---|---|---|
| Chattel Mortgage / CGL | May be claimable by the business | Business owns while lender takes security |
| Hire Purchase | May be claimable by the hirer | Tax treatment must be confirmed |
| Finance Lease | Lessor generally claims tax depreciation | Lessee payment and AASB 16 treatment is separate |
| Operating Lease | Lessor generally claims tax depreciation | Lessee payment and AASB 16 treatment is separate |
Use this transaction sequence; it does not guarantee approval or a tax outcome:
| When | Action |
|---|---|
| Business case | Identify the job, capacity gap, utilisation and downside case. Obtain comparable supplier quotes. |
| Evidence | Prepare financials, bank statements, asset details, seller identity and business-use records. |
| Finance comparison | Compare term, deposit, residual, fees, early-exit cost and total repayment — not only the headline rate. |
| Before June 30 | Ensure the asset is delivered, installed, and ready for use. Take photos with dates as evidence. |
| After June 30 | Give the accountant the contract, tax invoice, proof of payment/use and logbook or apportionment evidence. |
A construction business is considering a $150,000 ex-GST excavator. That cost is far above a proposed less-than-$20,000 write-off threshold, so the acquisition case must not assume an immediate $150,000 deduction.
| Input to Verify | Buyer Data | Decision Use |
|---|---|---|
| Utilisation and billing | Expected billable hours, rate and downtime | Tests whether operating margin covers repayments |
| Asset and delivery | Serial number, configuration, supplier and ready-for-use date | Supports valuation, lender and tax evidence |
| Finance structure | Deposit, term, residual, fees and total repayment | Exposes the end obligation and cash-flow downside |
| Tax and GST | To be calculated by the accountant under current law | Prevents a proposed or ineligible deduction entering the business case |
