Common Issues with Formal Business Valuation Reports
Accredited Business Valuation Specialists are required to adhere to professional standards and regulatory guidelines whilst preparing formal business valuation reports. The Australian Taxation Office (whom regularly audits business valuations) notes a wide range of common errors that it sees in tabled reports.

Everyday Errors and Issues
The Australian Taxation Office is increasingly conducting reviews of valuation reports to ensure compliance with applicable laws. As part of the ATO’s Market Valuation guidance published October 2022, the ATO reports the following common compliance issues:
- Inappropriate Methodology
Use of valuation methods that are unsuitable for the circumstances or not aligned with industry standards.
- Incorrect Application of Method
Errors in how methods (e.g. discounted cash flow, capitalisation of earnings) are applied, often inconsistent with accepted professional practice.
- Non-Compliance with Legal Frameworks
Valuations that do not reflect relevant tax law, superannuation rules, case law, or ATO guidance.
- Unreasonable Assumptions
Use of unrealistic inputs, historical data as a proxy without justification, or assumptions not grounded in evidence.
- Omission of Relevant Information
Failure to consider material facts available at the valuation date, including financial, operational, or legal information.
- Inconsistencies with Supporting Evidence
Discrepancies between the valuation and documentation such as contracts, shareholder agreements, or financial records.
- Use of Hindsight
Inappropriate reliance on post-valuation date events or forecasts not foreseeable at the valuation date.
- Incorrect Asset Apportionment
Errors in allocating value between tangible and intangible assets or across entities.
- Unsupported Adjustments
Lack of justification for risk adjustments, discount rates, or capitalisation multiples.

- Weak Base Analysis
Insufficient review of core financial and operational data used in the valuation.
- Averaging Errors
Inappropriate use of averages where more detailed analysis is required.
- Lack of Market Evidence
Inputs and assumptions not supported by independent market data.
- Failure to Verify Inputs
Use of subjective or unqualified assumptions without validation.
- Documentation Gaps
Missing critical assumptions, explanations, or working papers needed to support the valuation conclusions.
