When Accountants Need an Independent Business Valuer

Two professionals reviewing a financial report in an office, representing an accountant engaging an independent business valuer

A practical referral framework for accountants advising private business owners.

UPDATED JULY 2026

The accountant is often the most important source of information in a business valuation. Accountants understand the financial history, tax structure, owner remuneration, working capital and commercial context behind the numbers.

The question is not whether an accountant can calculate a value. Many can. The more useful question is whether the engagement requires an independent valuation conclusion that a third party may rely on, challenge or review.

KEY TAKEAWAY

Accountants should remain central to the valuation process. An independent valuer becomes particularly valuable when the purpose, reliance, complexity or perceived conflict requires a separate conclusion.

The accountant and valuer perform different but complementary roles

Accountant contribution	Independent valuer contribution
Reconciles historical accounts, tax returns and management reporting.	Defines the valuation purpose, date, interest and basis of value.
Explains owner remuneration, related-party entries and one-off events.	Tests normalisations and estimates maintainable earnings on a commercial basis.
Provides tax, structure and transaction context.	Selects and applies appropriate valuation approaches and cross-checks.
Supports forecasts and working capital analysis.	Assesses risk, transferability, market evidence and the conclusion of value.
Coordinates client records and responds to factual queries.	Documents assumptions, limitations and professional judgement in the report.

When an internal estimate may be sufficient

Not every question requires a formal independent valuation. A clearly labelled internal estimate or high-level calculation may be appropriate for early planning, management discussion or a low-stakes decision where no external party will rely on the result.

The scope and limitations should still be clear. A rule-of-thumb estimate should not later be repurposed for a tax event, dispute, financing application or shareholder transaction without reconsidering the engagement.

Seven referral triggers

A third party will rely on the conclusion. This may include the ATO, a court, a lender, an auditor, a trustee, a counterparty or an incoming shareholder.
The valuation supports a tax or related-party transaction. CGT events, restructures, employee equity, trust transactions and transfers between related parties can require market value evidence that is capable of review.
A dispute or relationship breakdown is possible. Family law, shareholder disputes, partnership exits and contested estates create a higher likelihood that methodology, assumptions and independence will be challenged.
The client is considering a sale or has received an offer. A commercially grounded valuation can separate enterprise value from equity proceeds, normalise earnings and identify the risks a buyer is likely to price.
The business or interest is complex. Multiple entities, unusual rights, minority interests, intellectual property, software, pre-revenue assets and specialised plant may require a dedicated valuation workstream.
The accounting firm faces a real or perceived conflict. Where the firm designed the transaction, advocates a tax position or has a close ongoing relationship, a separate valuer may strengthen independence in appearance as well as in fact.
The evidence is incomplete or the valuation date is historical. Retrospective matters and poor records require explicit assumptions, careful source selection and disciplined documentation.

Engagement scope should match the decision

The commercial label used by a provider is less important than the actual scope described in the engagement letter. APES 225 recognises valuation engagements, limited scope valuation engagements and calculation engagements for members providing valuation services. Each involves different freedom, evidence and reporting obligations.

Common service level	Typical purpose	Important limitation
Basic or indicative appraisal	Early planning, preliminary benchmarking or a low-complexity internal discussion.	Not designed for significant external reliance or a contested matter.
Estimate of Value or limited-scope analysis	Sale planning, internal shareholder discussions or commercial decision support.	The report should state the restrictions, information limits and intended users.
Formal valuation engagement	Tax, financing, legal, dispute or other third-party reliance purposes.	Requires a scope, evidence base and report appropriate to the purpose and scrutiny.
Special or complex valuation	IP, pre-revenue ventures, multi-entity groups, unusual rights or specialist assets.	May require additional experts, modelling and longer timeframes.

A formal report is not automatically the right answer for every client. Equally, a narrow calculation should not be presented as if it offers the same assurance and independence as a fully scoped valuation engagement.

A clean referral workflow

Clarify purpose and users. Ask why the valuation is required, who will rely on it and what decision or event it supports.
Confirm the valuation date and interest. Identify the entity, shares, business or asset being valued and the relevant point in time.
Share the available information. Provide financial statements, tax returns, current management accounts, forecasts, structure charts and key agreements.
Agree professional responsibilities. The accountant provides tax and factual input; the valuer owns the valuation analysis; the lawyer addresses legal interpretation where required.
Keep the accountant involved. The most efficient valuations are collaborative. The accountant can resolve reconciliations quickly and help the client understand the financial information requested.

Independence can protect the client relationship

Referring the valuation conclusion does not mean giving away the client. It can reduce the accounting firm’s self-review and advocacy risk while allowing the firm to continue providing the tax, accounting and commercial advice the client already values.

The client receives a clearer division of responsibility, and any third party can see how the financial inputs, tax advice and independent valuation conclusion fit together.
