Search results often use "net operating loss" or "NOL deduction." Australian legislation uses the term tax loss. This article covers eligibility, carry-forward rules, ownership tests, calculation, records and claiming for Australian companies.
Key Takeaways
- An accounting loss is not automatically a tax loss; tax rules decide the result.
- Carried-forward losses stay available only if ownership or business continuity tests are met.
- Losses usually reduce future taxable income, though the new carry-back regime can produce a refundable offset.
- Ownership changes, acquisitions, consolidation and thin records can all put losses at risk.
What Is a Net Operating Loss for a Corporation?
Tax loss versus accounting loss
In plain terms, a net operating loss arises when allowable deductions exceed assessable income for an income year. Under ITAA 1997 s 36-10, you total the year's deductions (excluding deductions for earlier tax losses), subtract assessable income, and subtract net exempt income where it applies. A positive remainder is the tax loss.
That differs from the book loss in your financial statements. The company tax return reconciles accounting profit or loss to taxable income or loss, and the common adjustments include:
- Accounting depreciation versus the tax decline in value
- Non-deductible expenditure
- Exempt and non-assessable income
- Provision movements
- Other timing differences
Why corporate tax losses matter
Loss rules align a company's tax burden with its actual profitability across years. Here is a simple example.
| Income year | Taxable result | Tax loss recorded |
|---|---|---|
| Year 1 | Loss of $200,000 | $200,000 |
| Year 2 | Profit of $300,000 before loss | Loss deducted: $200,000 |
| Year 2 taxable income | $100,000 | Balance: nil |
The Year 1 loss does not trigger a refund. It reduces Year 2 taxable income, provided the company meets the loss tests.
Corporation-level treatment
The loss belongs to the company, a separate legal entity. Shareholders cannot claim it as a personal deduction; the loss stays with the company.
How Corporate Tax Loss Deductions Work in Australia
Current Australian framework
Division 36 of the ITAA 1997 governs tax losses. The ATO confirms that company losses carry forward indefinitely, subject to the company loss requirements.
Key mechanics:
- A company can choose how much loss to deduct, including nil.
- Net exempt income absorbs losses first.
- Where there are several losses, the oldest is used first.
US concepts such as the TCJA 80% limit, CARES Act carrybacks or Section 172 do not apply to an Australian company.
Carry-back: old and new
The temporary pandemic scheme (former Division 160) covered losses from 2019-20 to 2022-23, with offsets claimed in the 2020-21, 2021-22 or 2022-23 returns. It is closed.
A new regime has since been enacted. Treasury Laws Amendment (Tax Reform No. 2) Act 2026 replaces Division 160 for income years starting on or after 1 July 2026.
Eligible corporate entities can carry losses back to either or both of the two preceding income years and claim a refundable tax offset. Significant global entities are excluded, and a franking-account cap applies. Carry-back is available again under these rules, not simply expired.
Applying losses to future income
Eligibility is tested across the period from the start of the loss year to the end of the deduction year. A carried-forward loss reduces taxable income, but tax remains payable on whatever income is left.
Unrelated obligations such as GST or PAYG are unaffected.
Consolidated groups and acquisitions
Within a tax-consolidated group, subsidiaries are treated as part of the head company. When a company joins, s 707-120 transfers its loss only to the extent it could have used it under a hypothetical test. Transferred losses are also limited by an available fraction (ss 707-305 to 707-320).
Acquisitions do not automatically carry losses to a new owner. Foreign ownership through interposed companies triggers the alternative ownership tests.
Eligibility Tests and Limitations for Carrying Losses Forward
Continuity of ownership
Under s 165-12, the same persons must hold more than 50% of voting power, dividend rights and capital distribution rights at all times from the start of the loss year to the end of the deduction year. Counting shares alone is not enough.
Problems can arise even when trading continues, for instance:
- Changes in direct or indirect ownership
- Changes to share classes or rights
- Intermediate holding companies in the chain
Same business and similar business tests
A company failing the ownership test may still rely on a business test.
The same business test (s 165-210) is explained in TR 1999/9. The similar business test (s 165-211) applies to losses from income years beginning on or after 1 July 2015.
The ATO's LCR 2019/1 gives two examples involving a courier business, ToUrDoor Pty Ltd:
- Adding food delivery with existing staff, branding and app, with parcels still central: similar business test satisfied.
- Food delivery becoming the dominant activity: test not satisfied.
Abandoning the original business or relying on wholly new assets typically fails both tests.
Loss categories and exclusions
- Net capital losses cannot be deducted from ordinary income. They reduce capital gains only.
- Net exempt income reduces the loss.
- Bad debt deductions face their own continuity conditions.
- Commercial debt forgiveness (Division 245) reduces prior tax losses first.
Anti-avoidance and due diligence
Buying a company just for its losses attracts scrutiny under Division 175 (income injection) and Part IVA.
Before any acquisition or restructure, run tax due diligence on:
- Loss schedules
- Ownership records
- Past returns
- Supporting calculations
How to Calculate, Track and Claim a Corporate Tax Loss
Step 1: Start with reliable accounting records
Begin with the profit and loss statement, trial balance, general ledger and source documents. Then reconcile accounting profit or loss (item 6 T) to taxable income or loss (item 7 T). Not every accounting expense is deductible.
Step 2: Determine the tax loss
Work through assessable income, allowable deductions, non-deductible items, capital items and depreciation. Hypothetical example:
| Item | Amount |
|---|---|
| Assessable income | $400,000 |
| Allowable deductions | $520,000 |
| Tax loss for the year | $120,000 |
| Used next year against $90,000 taxable profit | $90,000 |
| Balance carried forward | $30,000 |
Step 3: Check availability before using the loss
- Confirm the ownership test period and continuity
- Review business activities for changes
- Check consolidated-group status
- Reconcile prior utilisation
- Identify any special limits
Reassess after share transfers, restructures, acquisitions, disposals or a change in the business.
Step 4: Claim and report the loss
On the 2026 company tax return, item 7 R records tax losses deducted. Item 13 U records tax losses carried forward and item 13 V records net capital losses carried forward.
The Losses schedule 2026 is required where carried-forward tax and net capital losses exceed $100,000, among other triggers. Keep a schedule showing the loss year, original amount, amount used, balance and the tests supporting continued availability.
Records and audit readiness
Keep:
- Lodged returns and tax reconciliations
- Financial statements
- Ownership registers and share-transfer documents
- Group-structure charts
- Contracts, asset records and deduction calculations
Loss records may need to be held beyond five years, until the amendment period for the assessment in which the loss is used expires. Consistent tracking prevents omitted losses, double use and unsupported claims.
Planning Opportunities, Common Mistakes and Professional Support
Planning opportunities
Forecast taxable income and keep an up-to-date loss schedule. It helps directors time investments, asset sales and restructures. A loss is never a reason to enter an uneconomic deal. Test whether a planned transaction could restrict or wipe out the loss.
Common mistakes to avoid
- Confusing a book loss with a tax loss
- Assuming losses always transfer
- Applying US NOL rules
- Ignoring ownership changes
- Overlooking capital-loss treatment
- Failing to retain evidence
The ATO's revenue losses guidance flags losses used without meeting continuity requirements and deductions exceeding carried-forward balances. Check ATO guidance and legislation each year, as the 2026 carry-back change shows.

That includes maintaining ledgers, reconciling accounting and tax results, tracking carried-forward losses and organising documentation. Its tax due diligence work looks at compliance status and potential liabilities in transactions.
Treatment depends on structure and jurisdiction. Complex ownership changes, consolidated groups and legal conclusions should be reviewed by a qualified tax professional.
Frequently Asked Questions
What is a net operating loss?
It is a loss that arises when expenses or allowable deductions exceed income for a tax year. Australian legislation generally calls it a company tax loss.
Can a corporation carry forward a net operating loss in Australia?
Yes, indefinitely. The company must still satisfy the ownership, business continuity and other statutory conditions when it deducts the loss.
How do companies use tax losses to reduce future taxable income?
The loss is recorded and deducted against eligible future taxable income in the company tax return. The amount used depends on the current rules and the remaining balance.
What is the continuity of ownership test for company tax losses?
It checks whether the same persons kept more than 50% of voting, dividend and capital rights throughout the test period. Indirect ownership and changes to share rights can matter.
Can a company carry back tax losses in Australia?
Eligible companies can under the new Division 160, for income years starting on or after 1 July 2026, via a refundable offset. The earlier pandemic-era scheme has closed.
Is an accounting loss the same as a tax loss?
No. An accounting loss follows financial reporting standards, while a tax loss applies tax-specific deductions, exclusions, depreciation and timing adjustments.
