Buying the clients, brand or shares of a tax or accounting practice does not give a buyer one blanket permission to continue every service. Before completion, map each service to the legal entity delivering it, the individuals responsible for it, and every statutory registration, licence, authorisation, membership certificate and insurance arrangement required on day one.

The transaction structure matters. In an asset purchase, the buyer’s entity will generally need its own regulatory position and cannot simply use the seller’s registration. In a share purchase, the registered entity may remain the same, but changes to directors, supervising practitioners, ownership, staff and services can still trigger notifications or undermine continuing eligibility. Treat continuity as a matter to prove with each regulator and professional body, not an assumption in the sale agreement.

Start with the services, not the firm’s label

“Accounting practice” can describe a mixed service business. Build a schedule from actual invoices, engagement letters and job codes covering tax returns, BAS work, bookkeeping, company secretarial work, management accounts, SMSF administration or advice, audits and any financial advice. Then identify for each line:

  • the contracting and invoicing entity before and after completion;
  • the person who prepares, supervises, signs or lodges the work;
  • the registration or authorisation relied on, including its conditions and expiry;
  • the professional membership and public-practice certificate relied on;
  • professional indemnity cover and any relevant territorial or service exclusions; and
  • the system, client appointment or regulator access needed to deliver the service.

Reconcile the schedule to revenue by service line. A registration issue affecting a small advisory service is different from one affecting most recurring fees. It may also reveal that the seller personally holds the credential supporting a material service while the employing entity, proposed buyer or remaining staff do not.

Test tax and BAS agent registration at both levels

The Tax Practitioners Board (TPB) says a person or entity providing tax agent services for a fee or reward must be registered unless an exemption applies. A company or partnership tax agent must have a sufficient number of registered individual tax agents to provide the services competently and supervise work; it must also meet requirements concerning directors or partners and professional indemnity insurance (TPB). BAS services have their own registration analysis.

Ask for current TPB register extracts for the seller entity and every registered individual, registration conditions, renewal dates, insurance evidence, supervision arrangements and any correspondence with the TPB. Compare that evidence with the post-completion organisation chart and realistic workload. Counting registration numbers is not enough if the only person with the relevant competence is departing.

For an asset deal, confirm whether the buyer entity needs a new registration number and when it can lawfully begin providing each service. For a share deal, test the continuing position after the buyer appoints directors or changes supervising personnel. The TPB says a change in business structure may require a new registration and registration number, and changes to company directors or partnership composition must be notified within 30 days (TPB). Obtain direct advice on the actual structure and completion sequence.

Identify separate ASIC permissions and service boundaries

Tax-agent registration and professional membership do not authorise every adjacent service. For example, ASIC explains that accountants giving financial product advice about acquiring or disposing of an interest in an SMSF must be covered by an Australian financial services licence, while some traditional or incidental accounting activities may fall outside the regime or within specific exemptions (ASIC). Review what staff actually recommend—not merely how the engagement is titled.

If the practice performs company audits, identify the registered company auditors, the audit appointments and who will remain responsible after completion. ASIC lists ongoing obligations for registered company auditors including maintaining details, independence, audit quality and compliance with registration conditions (ASIC). Other specialist services can have separate regimes. Ask a regulatory lawyer to prepare a complete perimeter analysis rather than treating tax, audit and advice permissions as interchangeable.

Check membership and firm-level professional obligations

Statutory registration is only one layer. A principal’s professional body may impose public-practice, ownership, branding, continuing professional development, insurance and practice-review requirements. CA ANZ states that an Australian resident member who is a principal providing accounting services to the public for reward must hold a Certificate of Public Practice, and that certificate holders are subject to quality and practice review (CA ANZ). CPA Australia requires public-practice certificate holders to report associated practice entities and use its update process for changes in role or practice structure (CPA Australia). Requirements differ by body and membership status, so seek written confirmation for every incoming principal.

For members within APESB’s scope, professional duties do not end with a valid certificate. APES 110 sets fundamental principles including integrity, objectivity, professional competence and due care, confidentiality and professional behaviour (APESB). APES 320 requires non-assurance practices to establish quality-management policies and procedures across areas including governance, client acceptance, resources, engagement performance, information and monitoring (APESB). A buyer should therefore assess whether the seller’s operating system is documented, effective and suitable for the buyer’s structure—not just whether a manual exists.

The TPB’s additional Code obligations address matters including proper client records, competence, quality-management systems and keeping clients informed (TPB). Review complaints, regulatory correspondence, internal incidents, file reviews, remediation and significant-breach assessments. Have advisers decide what must be disclosed, reported, remedied or reflected in transaction protections.

Evidence to request before commitment

Request a controlled registration pack containing:

  • regulator and professional-body register extracts, certificates, conditions and renewal calendars;
  • applications, annual declarations, review reports, undertakings and correspondence for at least the relevant diligence period;
  • service-line revenue mapped to responsible entities, individuals and permissions;
  • professional indemnity schedules, retroactive dates, exclusions, claims and notifications;
  • CPD records, competency matrices, supervision ratios and succession cover;
  • quality-management, client-acceptance, conflict, independence and complaint procedures, plus evidence they operate;
  • regulator portal, lodgement and client-authority transition plans; and
  • written regulator or professional-body guidance obtained for the proposed structure.

Independently search public registers and sample completed files. Verify who signed, lodged, advised and reviewed the work. Resolve discrepancies between the seller’s service descriptions, staff interviews, invoices and formal permissions.

Use a day-one readiness gate

Before signing an unconditional agreement—or before the relevant condition is satisfied—record a decision for each material service:

Question Satisfactory evidence Warning sign
Who may contract and invoice? Buyer entity’s required registration or documented confirmation of continuity Seller registration is assumed to transfer
Who may supervise and sign? Named eligible people with capacity, accepted roles and contingency cover Departing seller remains the only qualified person
Is the service within scope? Advice maps actual conduct to registration, licence or exemption Engagement title is used as the only test
Do professional obligations continue? Updated certificates, body notifications, insurance and review plan Membership logo is treated as firm-wide authority
Can operations begin at completion? Conditions, approvals, access and client steps have dated owners Applications or notifications are left until after settlement

Unresolved items may require a condition precedent, delayed service transfer, retained seller responsibility, narrower acquired scope, remediation, price protection or a decision not to proceed. Those are legal and commercial choices for the buyer and advisers; due diligence should expose the dependency rather than prescribe the contract.

When specialist advice is needed

Engage a lawyer experienced in professional-services acquisitions to advise on transaction structure, regulatory continuity, client appointments, disclosure and drafting. Tax and accounting advisers can test service classification and capability; the relevant regulators and professional bodies can clarify application and notification processes. Insurance, audit, SMSF and financial-services specialists should review areas within their remit. Obtain advice early enough that approval lead times can shape the proposed completion date.
