Instant Asset Write-Off: Small Business Guide

The instant asset write-off is a valuable small business tax concession that lets eligible businesses claim an immediate deduction for the full cost of qualifying depreciating assets in the year they are first used or installed ready for use. This practical guide explains the rules, recordkeeping requirements, worked examples and next steps.

What is the instant asset write-off?

The instant asset write-off is an immediate deduction for eligible depreciating assets up to an applicable threshold in the income year the asset is first used or installed ready for use. Instead of depreciating an asset over multiple years, you may claim the full cost in one year if the asset and your entity meet the rules.

Key points:

• Applies to depreciating assets used in carrying on a business
• Claimed in the income year the asset is first used or installed ready for use for a taxable purpose
• Thresholds are generally tested on a GST-exclusive basis for GST-registered entities
• Exclusions include certain intangible assets, capital works and assets used predominantly for private purposes (which require apportionment)

For official guidance, see the ATO instant asset write-off page and the summary on business.gov.au.

Who can claim it?

Typical eligible entities include sole traders, partnerships, companies and trusts.

Primary eligibility tests:

• Aggregated turnover: your entity must meet the aggregated turnover threshold that applied for the relevant period. Thresholds have changed over time.
• Business use: the asset must be used in carrying on a business or be held ready for business use.
• Exclusions: assets held mainly for private use or certain capital or intangible items are not eligible without apportionment.

Aggregated turnover includes your business turnover and the turnover of connected or affiliated entities. For group structures, consult the ATO or your tax agent.

Special cases such as primary producers and some industry-specific assets may have different treatments — check ATO guidance. If you acquire an asset before the business starts, the timing of "first used or installed ready for use" needs careful consideration.

If unsure whether your entity meets the tests, see the Small business entity guide or seek professional advice.

How it works in practice

Timing is critical. An asset must be first used or installed ready for use in the income year to claim the write-off. "Installed ready for use" means the asset is physically ready to perform its business function.

Cost test: Compare the GST-exclusive cost to the threshold for the year the asset becomes ready for use.

GST treatment: If GST-registered you generally claim the GST credit on your BAS and test the threshold on the GST-exclusive price.

Assets above the threshold: If cost exceeds the threshold you cannot instant write-off that item. Options include small business simplified depreciation (small business pool) if eligible, or normal capital allowances (depreciation) over time.

Second-hand assets: May qualify if they meet timing, cost and business-use rules.

Assets acquired under finance or hire purchase: Deduction is based on the ready-for-use date, not payment dates. Consider asset finance or equipment finance options as part of your planning.

Private use apportionment: If the asset is partly private, apportion the deduction and keep usage records or logbooks.

Leases and classification: Treatment depends on whether the lease is a finance lease or operating lease. See Finance lease and Novated lease for detail.

Interaction with other concessions

Small business simplified depreciation (pool): If you cannot write-off an asset immediately, you may allocate it to the small business pool and claim a pool deduction each year. See Plant and equipment and Depreciation.

Temporary full expensing vs instant write-off: Temporary full expensing allowed many businesses to immediately deduct most depreciating assets during its effective period and often superseded the instant write-off where applicable. Compare which concession gives the better immediate tax outcome.

Low-value pooling, R&D and other rules: Low-value or low-cost asset rules and R&D concessions may change the outcome. Check the relevant concessions before deciding.

Claiming, recordkeeping and timing

Step-by-step claiming:

1. Confirm eligibility: entity type, aggregated turnover and business use for the relevant date.
2. Determine ready-for-use date: document installation, commissioning or training that made the asset ready.
3. Calculate GST-exclusive cost for threshold testing (if GST-registered).
4. Apportion private use if applicable; retain logbooks or usage records.
5. Choose the concession: instant write-off, temporary full expensing (if available) or small business pool.
6. Claim the deduction in the correct income year on your tax return schedules.

Essential records (retain for at least five years):

• Tax invoices and receipts showing purchase price (GST-exclusive and GST-inclusive)
• Bank statements or finance agreements proving payment or financing
• Installation or commissioning records (photos, emails, service reports) showing the ready-for-use date
• Logbooks or usage records to support private use apportionment
• Hire-purchase or finance contracts and repayment schedules if relevant
• Evidence of allocation for pooled assets

BAS/GST rules: If GST-registered, claim the input tax credit on the BAS period in which you are entitled to it (subject to BAS timing rules). Threshold testing is usually GST-exclusive.

Simplified accounting: If you claim an instant write-off, record the full deductible amount as an expense for the year and keep supporting invoices and installation evidence. If you finance the asset, record the finance liability separately. The timing of the tax deduction still follows the ready-for-use date. If you use bookkeeping software, attach scanned receipts and commissioning proof to each transaction for audit readiness.

Worked examples

Example 1 — Sole trader under threshold: You buy a new laptop on 15 May 2025 for $1,800 (GST-inclusive). GST = $180, GST-exclusive cost = $1,620. Threshold for your tax year is $10,000. Laptop was used on purchase date. Claim full instant write-off of $1,620 in 2025. If business use is 80%, claim $1,296 (80% × $1,620).

Example 2 — Company asset above threshold (pooled): Company acquires a $10,000 fridge, installed 10 March 2024. Threshold is $10,000 for that period. Cost exceeds threshold, so no instant write-off applies. Allocate to the small business pool (if eligible) and claim pool deductions each year. See Depreciation and Plant and machinery for detail.

Example 3 — Hire purchase / finance: You acquire a $15,000 van on finance, first used 1 Sept 2024. You may be able to claim the deduction for the year ended 30 June 2025 if the threshold allows. Deduction follows ready-for-use date (1 Sept 2024), not payment dates.

Example 4 — Part private use: $10,000 photographic kit used 70% for business: deductible portion is $1,000 if it meets the threshold and was ready for use in the income year.

These examples simplify outcomes. Reconcile final claims with your tax return and ATO schedules.

Common mistakes and audit triggers

Frequent errors include claiming in the wrong year by using invoice date instead of ready-for-use date; failing to apportion private use or lacking logbook evidence; testing thresholds on GST-inclusive amounts when GST-exclusive is required; misclassifying assets that are capital works or intangible; and providing inadequate installation or commissioning documentation.

Audit triggers often involve clusters of large write-offs near end of financial year without installation proof; repeated small business concession claims despite aggregated turnover exceeding thresholds; and missing or inconsistent invoices and bank records.

Practical tips to avoid errors: photograph assets in place on installation day and timestamp files; keep a short commissioning memo for each asset; and reconcile bookkeeping purchases to tax schedules annually.

FAQ

Key takeaways

The instant asset write-off can deliver an immediate tax benefit if an eligible entity purchases and first uses or installs an asset within the relevant income year and the asset cost is at or below the applicable threshold. Always test thresholds on GST-exclusive amounts (if GST-registered), document the ready-for-use date, apportion private use, and retain invoices and commissioning evidence for at least five years. Compare the instant write-off with temporary full expensing and small business pooling to choose the concession that best matches your tax and cashflow objectives.
