Key takeaways
Recurring fees matter when they transfer and remain profitable.
Annual tax, BAS, financial statement and bookkeeping work is valued for its reliability. The analysis must test whether clients are likely to stay after the principal who serves them leaves.
Client relationships often sit with a person, not the firm.
Where a retiring partner holds the key relationships and performs final review, value depends on a credible handover and on replacement capacity being costed into earnings.
Fee quality matters as much as fee volume.
Recoverability, write-offs, aged debtors, work in progress, pricing discipline and the mix of compliance and advisory work show how much of the gross fee base produces sustainable profit.
Retention and clawback terms change what the price really is.
Separate underlying business value from retention-adjusted price, deferred consideration and clawback effects. Where instructed, assess their financial effect on expected seller proceeds separately.
Registration, records and privacy obligations shape the transfer.
Tax/BAS registration can belong to an individual, company or partnership; share and asset sales differ. Plan required client permission, five-year record retention and applicable designated-service AML/CTF costs.
Why accounting practices need a specialist approach
Accounting and bookkeeping practices look simple to value from the outside: a block of recurring fees, a loyal client base and predictable seasonal workflow. In practice, the value of a firm depends on how much of that fee base will genuinely transfer to a new owner, what it costs to keep serving those clients and how the sale terms share the risk of clients leaving.
Practices change hands for many reasons—a principal retiring, partners merging, a key employee buying in, a practice acquiring a client book, or a partner leaving. Each situation raises a slightly different valuation question, but all of them turn on the same evidence: the quality of the fees, the strength of client relationships and the people needed to deliver the work.
Understanding the fee base
The starting point is a clear analysis of fees. That means more than the total on the profit and loss statement. A useful fee analysis separates:
Recurring compliance fees are an important value driver because they repeat, but they are not necessarily the dominant revenue source for every firm. Advisory fees can be valuable, but their predictability depends on the service model, repeat demand and the expertise and relationships of particular people.
Recurring compliance work: annual tax returns, BAS and IAS lodgements, financial statements, payroll and bookkeeping.
Advisory and project work: structuring, transaction support, business advisory and one-off engagements.
Fees by client and client group: showing concentration and the share of revenue from the largest relationships.
Fees by service line and staff member: showing who delivers the work and where capacity sits.
Fee quality, recoverability and work in progress
Gross fees can overstate the economic base. Examine billing rates against recorded time, write-offs and write-ups, aged debtors and the age of work in progress. Persistent write-offs on certain clients or services suggest pricing that does not reflect the effort required. Long debtor days may mean cash is tied up or some fees will never be collected.
Work in progress and debtors also need a clear position in the valuation. Are they included in the price, settled separately or retained by the vendor? Whatever the answer, the valuation should state it, because it changes the amount attributable to the interest being valued. Work in progress, debtors and other working-capital balances must be reconciled consistently with the adopted enterprise or equity valuation to avoid double counting where normal working capital is already included in enterprise value.
Signed
A clear valuation conclusion starts with an agreed purpose, relevant evidence and disclosed assumptions. The report identifies the interest valued and explains the reasoning behind its conclusion.
Partner and principal dependency
In many small firms, the principal holds the key client relationships, signs off technical work and brings in new clients. When that person leaves, some clients may follow them, retire with them or use the change as a reason to review their adviser.
The valuation tests that dependency directly. Who manages each significant client? Who performs final technical review? Is there a qualified successor with available capacity? Will the departing principal remain for a handover period? Earnings should include a realistic cost for replacement review capacity, rather than assuming existing staff will absorb the work without extra remuneration.
Client retention and transfer
Retention is the heart of accounting practice value. Evidence can include client tenure, historical attrition, the proportion of clients on recurring engagements, communication with clients about the change, and the experience of comparable transitions.
Practice sales commonly include retention or clawback arrangements, under which the price is adjusted by reference to fees retained over an agreed period. A valuation should distinguish the underlying business value from any transaction price subject to client-retention adjustments, deferred consideration or clawback provisions. Where those terms form part of the instructed analysis, their financial effect should be assessed separately and explained. Conditional payments can affect the present value of the seller’s expected proceeds without changing the underlying business value by the same amount.
Staff, capacity and technology
The people who deliver the work are part of the value. Consider staff tenure, qualifications, remuneration relative to market, workloads at peak periods and the likelihood of key staff staying after a change. Recruitment in accounting can be slow and costly, so the risk of losing experienced staff is real.
Technology matters too. Practice management, tax and ledger software subscriptions, data-hosting arrangements and file completeness affect handover cost and buyer confidence. A buyer will want to know whether client data is organised, complete and transferable within the relevant obligations.
Registration, records and privacy
Tax practitioner registration and business transfers
Individuals, partnerships and companies may be registered as tax or BAS agents with the Tax Practitioners Board. Registration belongs to the registered practitioner or entity and cannot simply be assigned to another person or legal entity. A company or partnership providing services requiring registration must hold its own registration and maintain appropriately registered individual practitioners and supervisory arrangements.
In a share sale, a registered company remains the same legal entity, although changes to ownership, directors, registered individual practitioners or supervisory arrangements may affect its ongoing eligibility and notification obligations. In an asset or client-book sale, the acquiring practitioner or entity must hold the registration required to provide the relevant services.
The transaction should also address ongoing registration eligibility, client authorities, confidentiality, record retention and professional obligations. Legal and professional advisers should confirm the requirements for the proposed structure rather than assuming a sale transfers every authority needed to operate.
Client confidentiality and record retention
Client records contain confidential tax, financial and personal information. Disclosure to a prospective purchaser or another practice must comply with applicable professional confidentiality obligations, including obtaining client permission where required under the TPB Code of Professional Conduct, unless a legal duty requires disclosure. Notification alone is not a substitute for required permission.
Applicable privacy and tax-file-number requirements must also be considered. Privacy Act obligations depend on whether the business is covered and the nature of the information being transferred. Client communications, engagement authorities, access arrangements and secure transfer procedures should be planned before completion. This does not mean every share sale automatically requires individual client consent.
The TPB’s expanded recordkeeping requirements under section 30 of the Tax Agent Services (Code of Professional Conduct) Determination 2024 require registered tax practitioners to retain specified records of tax and BAS services for at least five years after the relevant service is completed. The requirements commenced on 1 January 2025 for practices with more than 100 employees and 1 July 2025 for practices with 100 or fewer employees. A practice sale should address which entity retains historic records, how lawful access is maintained and how both parties will meet their continuing obligations. Buying access to client records does not automatically transfer the seller’s historic professional responsibilities.
Anti-money laundering obligations
From 1 July 2026, Australia’s expanded AML/CTF framework applies to accounting practices providing certain designated services, including specified company, trust and transaction-related services. It does not automatically apply to every accounting or bookkeeping activity. Affected newly regulated businesses were required to enrol with AUSTRAC by 29 July 2026.
Where applicable, the valuation should consider compliance costs, customer due-diligence requirements, staff training, recordkeeping, reporting and any unresolved regulatory exposure. These costs should be reflected in maintainable earnings rather than assuming historical compliance expenses remain representative. Confirm which services are covered before projecting a compliance cost or assuming the practice is outside the regime.
Choosing a valuation method
Practices are often discussed in terms of a multiple of recurring fees. That shorthand can be a useful cross-check, but it hides differences in profitability, retention, pricing and staffing between firms. Two practices with the same fees can have very different values if one is profitable, well staffed and diversified and the other depends on a single principal and discounted pricing.
The appropriate valuation method depends on earnings quality, client retention, business structure and available market evidence. Capitalisation of maintainable earnings is often useful, with comparable practice transactions and discounted cash-flow analysis considered where appropriate and supported by the available evidence and agreed scope. Maintainable earnings should include commercial remuneration for the principal's role and realistic staffing costs. Our guide to business valuation methods explains each approach.
Hypothetical example: a sole-principal practice
This illustration is not a client matter. A sole principal runs a suburban practice with steady annual fees, mostly individual and small business compliance work, two experienced staff and a part-time bookkeeper. The principal plans to sell to a larger firm within two years.
The valuation would analyse fees by client and service, test recoverability and debtor age, and assess how many relationships depend on the principal personally. Earnings would include a commercial cost for the principal's technical and management work. The report would distinguish underlying business value from the financial effect of proposed retention terms, where instructed, and explain how work in progress and debtors are treated without double counting working capital. Scenarios could test the effect of a major client leaving or a key staff member resigning during the transition.
Scope, timing and how to start
IBV offers a Limited Scope Conclusion of Value for an accounting practice at a Fixed Professional Fee of $4,950 + GST, where suitable for the valuation purpose and circumstances. Suitability depends on the intended reliance, available evidence and agreed scope restrictions, not simply the size of the practice. Under APES 225, which IBV voluntarily aligns with, a Limited Scope Valuation Engagement involves material restrictions on the scope of work. Larger or more complex practices, or instructions requiring more extensive procedures, may require a separately quoted Full Conclusion of Value.
Standard delivery for a Calculated Value or Limited Scope Conclusion of Value is approximately 5–7 business days once the required information, clarifications, signed engagement documents and payment have been received. Complex engagements may take longer; Full Conclusion timing is confirmed for the engagement. Timing and suitability are confirmed before work begins.

Frequently asked questions
How are accounting practices valued?
The method depends on earnings quality, client retention, business structure and market evidence. Capitalisation of maintainable earnings is often useful; comparable practice transactions and discounted cash-flow analysis can also be considered where appropriate and supported by evidence and the agreed scope. Fee multiples are a cross-check, not a substitute for analysing profitability and replacement staffing costs.
Is a multiple of fees a reliable way to value a practice?
It is a useful cross-check but rarely sufficient alone. Two practices with the same fees can differ significantly in profitability, retention, pricing and staffing, which a single multiple does not capture.
How do retention or clawback clauses affect value?
They shift client-loss risk between buyer and seller. Distinguish underlying business value from a transaction price subject to retention adjustments, deferred consideration or clawback provisions. Where instructed, assess those terms separately: their effect on the present value of the seller’s expected proceeds need not equal their effect on business value.
Does my tax agent registration transfer with the practice?
Individuals, partnerships and companies may be registered tax or BAS agents. Registration cannot simply be assigned to another person or entity. In a share sale, a registered company remains the same legal entity, subject to continuing eligibility and notification obligations. In an asset or client-book sale, the buyer must hold the registration required for the services it will provide, with appropriate registered individuals and supervisory arrangements.
What happens to client files when a practice is sold?
Disclosure to a purchaser or another practice requires client permission where required under the TPB Code, unless a legal duty requires disclosure; notification alone is not a substitute. Consider applicable privacy and tax-file-number requirements, client authorities and secure transfer arrangements. This does not mean every share sale automatically requires individual client consent.
How does principal dependency affect value?
Where the principal holds key relationships and performs final review, some clients may not transfer. The valuation costs replacement capacity into earnings and assesses retention risk, which can affect the multiple.
Are work in progress and debtors included in the value?
They may be included, settled separately or retained by the vendor. Reconcile WIP, debtors and other working capital consistently with the adopted enterprise or equity value to avoid double counting where normal working capital is already included in enterprise value.
What records are needed to value an accounting practice?
Fee analyses by client and service, time and billing records, write-offs, aged debtors and WIP, staff details and remuneration, financial statements and tax returns, engagement terms and software arrangements.

Can you value a bookkeeping business as well?
Yes. Bookkeeping and BAS agent businesses raise similar questions about recurring fees, client retention, registration and staff capacity, and are valued using the same evidence-based approach.
Which IBV™ engagement suits an accounting practice valuation?
IBV offers a Limited Scope Conclusion of Value at a Fixed Professional Fee of $4,950 + GST where suitable for the purpose, intended reliance, evidence and agreed scope restrictions. It is not automatically suitable for every accounting practice. Instructions requiring more extensive procedures may need a separately quoted Full Conclusion of Value. Suitability and timing are confirmed before work begins.
How long must historic tax and BAS service records be retained?
Specified tax and BAS service records must be retained for at least five years after the relevant service is completed under section 30 of the TPB Code Determination 2024. The requirements commenced on 1 January 2025 for practices with more than 100 employees and 1 July 2025 for practices with 100 or fewer employees. Agree who retains historic records and how lawful access and continuing obligations will be met.
Do the July 2026 AML/CTF reforms apply to every accounting practice?
No. From 1 July 2026, the expanded framework covers practices providing certain designated services, including specified company, trust and transaction-related services, not every accounting or bookkeeping activity. Affected newly regulated businesses had to enrol with AUSTRAC by 29 July 2026. Include applicable due diligence, training, compliance, reporting and recordkeeping costs in maintainable earnings.
