Same Business Test for Company Tax Losses

The same business test can preserve a company’s carried-forward tax losses after continuity of ownership fails. Compare its business before the relevant test time with the whole claim year. Eligible loss years also have a separate similar business alternative.

When the Same Business Test Matters

An ownership change can move a company’s earlier tax losses into the business continuity rules before you claim a deduction. Start with the loss-year history and ownership evidence. A balance carried forward in the previous return does not establish that the company can deduct it now.

Keep the loss categories separate. An accounting loss comes from the financial statements and can differ from the tax loss after tax adjustments. A net capital loss belongs in the capital gains calculation and cannot reduce ordinary business income. Company ownership and business continuity rules can also restrict capital losses, but they need a separate schedule.

A sole trader’s deferred non-commercial loss is another category. The ATO’s company loss guidance confirms that the non-commercial loss rules do not apply to companies.

For each carried-forward tax loss, establish which test permits its use before calculating the deduction. Then place the result into the wider company tax compliance review.

Check Continuity of Ownership First

Continuity of ownership generally requires the same persons to retain more than 50% of each relevant right throughout the ownership test period. Test voting power, dividend rights and capital distribution rights separately. The period runs from the start of the loss year to the end of the income year claiming the deduction.

Build an ownership timeline for each loss year. Collect the share register and historical transfers, share issues and cancellations, the constitution and class rights. Obtain shareholder agreements and records for interposed entities where they affect the rights being traced. A company’s name or continuing directors do not establish who holds those rights.

Use the ownership chart behind the client’s group structure to trace direct and indirect interests under the applicable statutory tests. Avoid substituting a percentage of registered shares for an assessment of beneficial ownership and the actual rights attached. Special tracing rules and concessions can change the analysis.

Consider this fictional company with ordinary shares carrying equal rights. The original majority shareholder holds 60% and the other original shareholder holds 40%. The majority shareholder sells 20 percentage points to an outside buyer, leaving the original holders with 80% between them. That transfer alone does not break their majority continuity.

Later, the other original shareholder sells the entire 40% holding to that buyer. The original holders now retain only 40%, while the buyer holds 60%. On these assumptions, continuity fails at the later transfer. Record that event and its effective time, with the documents proving the positions on both sides.

Section 165-13 also applies when establishing continuity is impracticable. Its test-time table deals with the period you can substantiate, so missing history does not justify assuming the acquisition date. Check the separate change-of-control rule where relevant, even when the ownership percentages appear to pass.

Compare the Business Before and After the Change

The same business test compares the whole business immediately before the statutory test time with the business throughout the claim income year. For a documented ownership failure, the comparison normally starts immediately before that failure. A year-end description alone cannot establish continuity throughout the year.

Prepare a comparison from contracts, sales records and management accounts, supported by asset and staff records. Describe what generated income before the change and during the claim year. Identify customer markets, products or services, operating methods and the assets used, including goodwill. Explain closures or disposals of operations as well as additions.

Under section 165-210, separately assess income from a new kind of business and a new kind of transaction. An overall resemblance cannot overcome those restrictions. The legislation also prevents introducing activities before the test time for a purpose of manufacturing compliance with the test.

The ATO’s TR 1999/9 recognises that ordinary growth or contraction can preserve business identity. Expansion can also change its character enough to fail. Assess the facts and each statutory condition separately.

Fictional Business Histories

History	Ownership event	Business comparison	Assessment to record
Continuing repair business	An outside buyer acquires 70% of equal-right ordinary shares	The same workshop repairs the same equipment types throughout the claim year. Existing contracts continue, with replacement tools and some new customers.	These facts support continued business identity. Confirm the new-business and new-transaction restrictions before concluding that the same business test passes.
Replaced wholesale business	A buyer acquires 80% of equal-right ordinary shares	The company closes its wholesale operation, sells its stock and starts holiday accommodation using newly acquired assets.	The former income-producing operation has ended. Keeping the company name and directors does not preserve the same business.

For the repair company, a new customer is not automatically a new kind of business or transaction. Examine what the customer buys and how that activity fits the previous operations. For the former wholesaler, management’s intention to remain commercially active does not establish continuity of the discontinued business.

Identify When the Similar Business Test Applies

The similar business test is a separate route for losses from qualifying income years. It applies only where the loss year starts on or after the statutory commencement boundary. Match each loss year’s actual commencement to the eligibility rule in section 165-211.

Earlier loss years cannot use that alternative. If ownership continuity fails, assess those earlier losses under the same business test. A company with losses from several years can therefore need different business continuity conclusions for different balances.

The similar business test requires a comparison throughout the test period against the former business immediately before the test time. Take account of each statutory factor.

• How far the income-producing assets continue, including goodwill.
• How far the income-producing activities and operations continue.
• Whether the current business retains the former business’s identity.
• How far changes arise from development or commercialisation of the former business’s assets, products, processes, services or methods.

The factors require an overall assessment. The ATO’s LCR 2019/1 explains that operating in the same industry is insufficient. New activities that grow from the previous business can support similarity, while unrelated additions can undermine it.

For a third fictional history, an investor acquires 60% of a parts manufacturer with an eligible loss year. The company develops a compatible replacement component using its existing designs, machinery and production skills. It sells through its established distribution arrangements while continuing the earlier product line.

Those facts support similarity through continuing assets and operations, with development arising from the former business. Record the contribution of the new component to income and the continuing role of existing goodwill. A larger customer base alone neither proves nor defeats similarity. Test the business throughout the claim year and address the pre-test-time anti-avoidance condition before reaching a conclusion.

Complete the Loss Recoupment Record

Reconcile every loss year’s opening balance to earlier returns and adjustments, then record the applicable test, amount deducted and remaining balance. Keep tax losses separate from capital losses and accounting balances. Explain any reduction or correction before carrying a number into the return.

Fictional Loss Reconciliation

Assume the continuing repair company supports the same business test for both loss years. It has $30,000 of taxable income before prior-year tax losses. There is no net exempt income or other adjustment affecting the example.

Loss year	Opening tax loss	Amount deducted	Closing tax loss	Eligibility record
First loss year	$90,000	$30,000	$60,000	Ownership failure and same business conclusion documented
Later loss year	$35,000	$0	$35,000	Separate loss-year test documented; unused this year
Total	$125,000	$30,000	$95,000	Deduction agrees to the return

The $95,000 closing balance preserves each loss year separately. It does not certify eligibility for a later claim year, which extends the relevant testing period.

The preparer’s conclusion must identify the loss year, ownership test period and evidence for any failure or unproven interval. State the statutory test time and claim-year comparison period. Explain the deciding business facts, address the applicable restrictions and cross-reference the records supporting the conclusion. Record the deduction and closing balance, then give the reviewer a named sign-off field and review date.

If the business comparison remains materially uncertain, obtain specialist advice or consider an ATO private ruling before relying on the deduction. Provide the ownership timeline, loss schedule and evidence of the business on both sides of the change. A ruling request needs the actual facts, including discontinued operations and new income sources.

If the company joins a tax consolidated group, assess loss transfer and later utilisation under the additional tax consolidation rules. Ordinary company recoupment eligibility alone does not transfer a loss to the head company or establish how much it can use. Complete those group-entry checks before treating the loss as available in the group’s return.
