Australia instant asset write-off calculator

Enter an ordinary business asset’s full tax cost and first-use date. Check the threshold before applying your business-use percentage.

Inputs
AUD
Use the correctly determined tax cost after applicable GST adjustments, before business-use apportionment. Include all relevant cost elements. This tool does not calculate GST adjustments.
%
Confirm acquisition and first-use years using the prior-year, estimated-current-year or actual-current-year route. Current turnover of AUD 10 million or more does not alone disqualify you. This tool relies on your verified status; it does not determine it.
Also confirm small-business status in both years. This checker covers ordinary equipment only; not excluded assets, special depreciation categories, pools or disposals.

  • A deduction reduces taxable income; it is not a cash refund or an estimate of tax saved.
  • An asset failing this threshold may qualify for depreciation under other rules. Pool deductions, GST, vehicles, improvements and prior use are not calculated.

This is a general estimate for information only, not tax, legal or financial advice. Real rules have more conditions than a calculator can show, so check the official source below or a qualified professional for your situation.

How it works

The ATO’s verified profiles use a cost strictly below AUD 20,000 for verified small-business entities. Simplified depreciation and asset eligibility must also apply. The 2026 amendment makes the threshold permanent from July 1, 2026; this checker currently covers only 2025–26 and 2026–27.

Confirm small-business status in the acquisition and first-use years under section 328-110. A continuing business can qualify through previous-year turnover below AUD 10 million even if current turnover is higher. Other routes use estimated or actual current-year turnover. The estimate is made at the start of the year (or business commencement) and is unavailable if both preceding business years had turnover of at least AUD 10 million. This calculator relies on your verified status.

if eligible: deduction = full tax cost × business-use percentage ÷ 100

Test the full cost first. Enter cost after applicable GST adjustments, before business-use apportionment. No intermediate rounding is applied; displayed amounts round to cents.

Worked examples

Equipment below the limit

An AUD 18,000 asset first ready on June 15, 2026, used 80% for business gives an AUD 14,400 deduction for an eligible business. A continuing business with AUD 9 million previous-year turnover and AUD 12 million current-year turnover can qualify through the prior-year route.

Business portion below the limit is not enough

An AUD 25,000 asset at 60% business use has an AUD 15,000 business portion. Its full cost exceeds the threshold, so this immediate write-off is AUD 0.

Frequently asked questions

Does an asset costing exactly AUD 20,000 qualify?
No. The full cost must be strictly below AUD 20,000.
Is buying before June 30 enough?
The relevant timing includes first use or installation ready for taxable use. A purchase date alone does not establish the deduction year.
Is the deduction a refund?
No. It reduces taxable income. The tax saving depends on your circumstances and is not calculated here.
Can I use this for employee tools or cars?
No. This release covers ordinary business equipment. Employee expenses, vehicles, leases, improvements, prior private use and other complex assets need separate assessment.
What if the asset is over the limit?
Other depreciation rules may apply. This tool does not calculate a pool deduction or write off the first AUD 20,000 of a larger asset.
