Business Valuation for ATO Purposes: When You Need One and What Makes It Defensible

A business valuation for ATO purposes establishes the market value of a business or business asset for tax reporting. Not all valuations meet the standard the ATO expects. The difference between a defensible valuation and one that fails on review usually comes down to methodology, evidence and the qualifications of the valuer.

A business valuation for ATO purposes is required whenever the market value of a business or business asset must be substantiated for tax. The ATO assesses valuations on a risk basis. A defensible valuation uses more than one methodology, applies the ordinary meaning of market value, follows recognised professional standards, documents evidence and assumptions clearly, and is signed by a qualified independent valuer. Reports that fall short on any of these are at the highest risk of challenge.

When You Need a Business Valuation for ATO Purposes

The ATO requires a market valuation in a wide range of circumstances. The common triggers include:

• Capital gains tax events. Sale of business assets, transfer of shares, change in beneficial ownership, or any other CGT event where the market value of the underlying asset must be established.

• Non-arm's-length transactions. Transferring property, shares or business interests between related parties, including family members, related companies, or related trusts. The ATO requires the transaction to be at market value regardless of what consideration is actually paid.

• Small business CGT concessions. Where eligibility depends on meeting the $6 million net asset value threshold, the values of the relevant assets must be supportable.

• Employee share schemes. When a company offers shares or options to employees, the market value of those securities at grant must be defensibly established for income tax and CGT purposes.

• Restructures and rollovers. Genuine restructures, scrip-for-scrip rollovers, and similar transactions require supporting valuations of the assets being transferred.

• Self-managed superannuation funds. SMSFs that hold business or unlisted assets must report those assets at market value annually.

• Tax consolidation. Corporate groups consolidating for income tax purposes require valuations of the assets entering or leaving the consolidated group.

In each of these cases, the value reported on a tax return is not simply a number the taxpayer chose. It is a position that may be reviewed by the ATO, and the taxpayer needs to be able to substantiate it.

What "Market Value" Means in This Context

The starting point for any valuation for ATO purposes is the ordinary meaning of market value, as established by the High Court of Australia in Spencer v Commonwealth (1907). The Spencer test defines market value as:

"The amount a willing but not anxious buyer would pay to a willing but not anxious seller, both being fully informed about the asset and acting at arm's length."

This sounds straightforward in principle. In practice, applying the Spencer test to a private business or unlisted asset is the substance of the valuation work. There is no observable market price for a private company. The market value must be established by analysis: by examining comparable transactions, by valuing the future earnings the business is expected to generate, by considering the assets and liabilities of the entity, and by combining those approaches in a way that reflects how a real buyer and seller would think about the asset.

This is why the choice of valuation methodology matters so much. A valuation that uses a single, narrow approach risks producing a number that does not reflect what an informed market participant would actually pay.

What the ATO Looks For

The ATO does not certify valuations in advance. It assesses them on review, using a risk-based approach. Lower-risk valuations are accepted; higher-risk ones are challenged. The factors that move a valuation from higher to lower risk are well understood:

Use of more than one valuation methodology

This is one of the most important factors. The ATO expects a credible valuation to consider more than one approach where the asset and the data allow. Common methodologies include:

• Capitalisation of future maintainable earnings (often the primary method for established profitable businesses)

• Discounted cash flow analysis (where forecasts of future cash flows are reliable)

• Comparable transaction analysis (using observed sale prices of similar businesses)

• Comparable trading analysis (using market multiples of comparable listed companies)

• Net asset backing (for businesses where asset value is the primary driver, or as a cross-check)

A valuation that uses two or more of these methods, with the results cross-checked and reconciled, is materially more defensible than one that uses a single method without supporting analysis. Valuations relying on a single quick-rule-of-thumb ("three times EBITDA" or similar) without supporting methodologies are the most likely to fail on ATO review.

Adherence to recognised professional standards

The ATO weighs whether a valuation has been prepared in accordance with recognised professional standards. Two are particularly relevant in Australia:

• APES 225 (Valuation Services). Issued by the Accounting Professional and Ethical Standards Board. APES 225 sets standards for scope definition, independence, methodology, documentation and reporting.

• International Valuation Standards (IVS). The global standard issued by the International Valuation Standards Council. IVS sets out the principles of valuation practice that are recognised internationally and adopted by professional valuers in Australia.

A valuation prepared in accordance with the principles of these standards is structurally more defensible than one prepared without reference to any framework. The standards govern not just the analysis but the way it is documented and reported, which is where many valuations fall down.

Qualifications and independence of the valuer

The ATO weighs who prepared the valuation. A valuer with relevant experience, formal certification from a recognised professional body, and demonstrable independence from the transaction is given significantly more weight than an internal estimate or a valuation prepared by a party with a commercial interest in the outcome.

The relevant professional body for valuers in Australia is the Australian Valuers Institute (AVI), founded in 1938. AVI's Certified Business Valuer designation indicates formal certification in business valuation and ongoing professional development requirements.

For valuations of equity in a company (share valuations, related-party share transfers, employee share schemes), there is an additional regulatory layer. ASIC classifies equity valuation as a financial service under the Corporations Act, meaning equity valuations are required to be provided under an Australian Financial Services Licence. Many firms offering business valuations do not hold an AFSL, which is a structural risk for any taxpayer relying on those valuations for ATO purposes where equity is in scope.

Integrity of the valuation process

The ATO looks at how the valuation was conducted. Was the valuer given full access to the business's financial records, contracts, and operating data? Were assumptions tested rather than accepted at face value? Was the engagement scope clear and documented? A valuation prepared on incomplete or biased information will not stand up to scrutiny, regardless of how carefully the methodology is applied.

Documentation and reporting

Finally, the report itself must contain enough detail for the ATO to assess it. A defensible valuation report includes:

• A clear statement of the scope and purpose of the valuation

• A description of the asset being valued and the entity within which it sits

• The valuation date and the basis of valuation (typically market value as defined under Spencer)

• Details of the methodologies applied and why they were chosen

• The data and information relied upon, including financial statements, forecasts and market comparables

• All material assumptions, with explanations of how they were tested

• The identity and qualifications of the valuer, and a statement of independence

• The conclusion of value, with reconciliation between methods if more than one was used

Reports that simply state a number, without showing the working, are the most exposed to challenge. A defensible report enables the ATO to understand exactly how the value was reached and to test each step of the analysis.

Common Reasons Valuations Fail on ATO Review

From observation across the industry, the recurring reasons a valuation is challenged include:

• Use of a single methodology where multiple were appropriate

• Reliance on rule-of-thumb multiples without supporting analysis

• Valuer with insufficient experience or relevant qualifications

• Absence of certification from a recognised professional body

• Lack of independence (valuation prepared by a party with an interest in the outcome)

• No reference to recognised valuation standards

• Material assumptions stated but not tested or supported

• Documentation that does not allow the methodology and conclusions to be followed

• Valuation date not aligned with the relevant tax event

• For equity valuations, absence of an AFSL covering the work

Most of these are avoidable with proper engagement design at the outset. A defensible valuation is not necessarily expensive or slow, but it does require the right scope, the right valuer, and the right level of evidence.

Sherwood Australia is a corporate finance advisory firm specialising in business valuations. Our approach is designed to produce reports that meet the standards the ATO expects:

• Multiple methodologies as standard. We apply at least two valuation approaches on every engagement, with cross-checks and reconciliation between methods. Single-method valuations are reserved only for cases where the asset or available data genuinely supports nothing else.

• Prepared in accordance with recognised professional standards. Sherwood's valuations follow the principles of APES 225 and the International Valuation Standards. These standards govern scope definition, independence, methodology, documentation and reporting.

• Senior-led, with relevant credentials. Engagements are led by Anthony Vago, Managing Director, AVI Certified Business Valuer (AVI 20281), with over 30 years of combined experience in corporate finance advisory and business ownership.

• AFSL coverage where equity is in scope. Sherwood holds Australian Financial Services Licence 563351. For share valuations, related-party transfers, and other equity work, the valuation is provided under that licence.

• Independent and demonstrably impartial. We have no interest in the transaction or its tax outcome. Engagement terms, scope and methodology are documented at the outset.

• Reports built for review. Our reports include the methodology, assumptions, evidence and reconciliation needed for an ATO reviewer to follow the analysis from inputs to conclusion.

• Coordinated with your tax advisor. We work alongside accountants and tax specialists, not in place of them. Where tax advice is needed, that comes from your tax advisor; we provide the supporting valuation.

Frequently Asked Questions

When do I need a business valuation for ATO purposes?

Whenever the market value of a business or business asset must be substantiated for tax reporting. Common situations include CGT events, non-arm's-length transactions between related parties, employee share schemes, small business CGT concession threshold tests, restructures and rollovers, SMSF asset reporting, and tax consolidation. If a tax position depends on a market value figure, that figure should be supportable.

What does the ATO consider a defensible business valuation?

A valuation that uses more than one valuation methodology where appropriate, applies the ordinary meaning of market value as defined in Spencer v Commonwealth, is prepared in accordance with recognised professional standards (such as APES 225 and the International Valuation Standards), documents all assumptions and evidence, and is signed by a qualified independent valuer. The ATO assesses valuations on a risk basis, weighing methodology, qualifications of the valuer, integrity of the process, and the quality of documentation.

What credentials should I look for in a business valuer for ATO purposes?

Look for independence from the transaction, demonstrable experience in business valuation specifically (not general accounting or audit), formal certification from a recognised professional body, and adherence to recognised valuation standards. In Australia, the Australian Valuers Institute (AVI) is the national professional body for valuers; an AVI Certified Business Valuer designation indicates formal certification in business valuation. Valuations prepared in accordance with the principles of APES 225 and the International Valuation Standards apply the standards of practice the ATO and other reviewers expect. For equity valuations specifically, the valuer should be working under an AFSL.

Can my accountant prepare a valuation for ATO purposes?

Some accountants are qualified to prepare business valuations and do so routinely. Others recommend a specialist valuer for valuations that need to withstand ATO scrutiny, particularly where the amounts are significant, where multiple methodologies are required, or where equity in a company is involved. Working with an independent specialist valuer alongside your accountant is often the most defensible approach.

Why does the AFSL matter for some valuations?

ASIC classifies equity valuation as a financial service under the Corporations Act. Valuations of shares, units or other equity interests are therefore required to be provided under an Australian Financial Services Licence. Sherwood Australia holds AFSL 563351. The AFSL is not required for all business valuation work, but where equity is being valued (for example in related-party share transfers, ESOPs, or CGT events on shares) it is a structural requirement.

How long does a business valuation for ATO purposes take?

A standard business valuation takes up to 10 business days from receiving all required documents to the final report, depending on the complexity of the business, the availability of financial records, and the scope of the methodologies required. Time-critical situations can sometimes be accommodated; the trade-off is on the depth of supporting analysis.

What does a business valuation for ATO purposes cost?

Fees depend on the scope of the engagement, the complexity of the business, the methodologies required, and the level of supporting analysis. Sherwood provides a fixed-fee proposal after an initial scoping discussion. As a general guide, a defensible business valuation for ATO purposes is a meaningful piece of work and the fee reflects that. The cost should be considered in the context of the tax exposure and the consequences of a valuation failing on review.

What happens if the ATO challenges a valuation?

The ATO may seek additional information, request a revised valuation, or in some cases substitute its own value. The taxpayer carries the burden of supporting the value reported. A well-prepared valuation that documents methodology, evidence and assumptions is significantly less likely to be challenged in the first place, and significantly easier to defend if it is.

Does Sherwood Australia provide tax advice?

No. Sherwood Australia is a corporate finance advisory firm providing valuations, IP valuations, licensing and business sales services. We work alongside our clients' tax advisors, who provide tax advice. For tax advice you should consult a qualified tax advisor.
