In addition, please note that the principles and examples in this TPB(PN) do not constitute legal advice and do not create additional rights or legal obligations beyond those that are contained in the TASA or which may exist at law.
The TPB originally released this document as a draft practice note in the form of an exposure draft on 10 May 2019. The closing date for the submissions was 7 June 2019.
The TPB considered the comments and submissions received and now publishes the following TPB(PN) based on the TASA as at 15 March 2017. This practice note replaces TPB(I) 01/2011: Letters of engagement.

- This practice note has been prepared by the Tax Practitioners Board (TPB) to provide practical guidance and assistance to registered tax agents and BAS agents (collectively referred to as tax practitioners) to understand the TPB’s position in relation to the provision of letters of engagement to clients. For the purposes of this practice note, any reference to tax agent services includes BAS services and tax (financial) advice services, unless otherwise stipulated.
- In this practice note, you will find the following information:
- what is a letter of engagement and what can it cover? (paragraphs 3 to 6)
- are letters of engagement required by the Tax Agent Services Act 2009 (TASA)? (paragraphs 7 to 14)
- suggested matters to include in letters of engagement (paragraph 15 and 16)
- the TPB’s position in relation to recurring or ongoing engagements (paragraph 17)
- where to find further information (paragraph 18)
- the use of template or example letters of engagement (paragraph 19).
- The agreement between a service provider, such as a tax practitioner, and client which sets out the agreed terms and conditions of the engagement, when presented in the form of a letter, is sometimes referred to as a ‘letter of engagement’ or an ‘engagement letter’. This agreement may also include a variety of written communications, including a formal agreement, a standard form handout, brochure, leaflet or electronic communication.
- It is the TPB’s view that using letters of engagement can assist tax practitioners to establish a clear understanding of the elements of engagement between tax practitioners and their clients. Further, letters of engagement are a simple way to set out the business practices the tax practitioner has in place to assure clients that the tax practitioner complies with the requirements of the TASA and to assist in avoiding uncertainty and misunderstandings, especially in relation to disputes over fees and about the scope of the work to be completed. Given the nature and implications of letters of engagement (or similar agreements) tax practitioners should consider obtaining legal advice in relation to the letters of engagement provided to clients.
- In relation to tax (financial) advisers, the Corporations Act 2001 requires the provision of disclosure information at the commencement of a client engagement in certain circumstances, including the provision of a Financial Services Guide, general advice warning and Statements of Advice. Similarly, the TPB is of the view that all tax practitioners should provide and seek acceptance of relevant matters at the commencement of a client engagement, prior to the provision of tax agent services to the client. For tax (financial) advisers, this may be achieved in conjunction with the disclosure requirements of the Corporations Act 2001. In this regard the TPB does not expect tax (financial) advisers to provide disclosure information and documentation additional to what they are legally obliged to under the Corporations Act 2001 and by other regulators, in circumstances where this additional disclosure information and documentation adequately addresses the matters set out in this practice note.
- A letter of engagement is generally the starting point in the ongoing communication between a tax practitioner and client about:
- what is to be done
- who will do it
- how it will be done
- when it is to be done
- how much the work will cost.
- While letters of engagement are not a specific requirement of the Code of Professional Conduct (Code) in the TASA, the TPB is of the view that the provision of letters of engagement, covering the matters outlined in this practice note, is an important and effective mechanism to assist tax practitioners in ensuring that they comply with the requirements of the Code. Where relevant, it is for this reason that, when considering whether a tax practitioner has breached the Code, the TPB takes into account the existence and content of a letter of engagement between the tax practitioner and client/s. As such, the TPB strongly encourages the use of letters of engagement as a means of avoiding uncertainty and misunderstandings and to assist in compliance with the Code. However, each case will depend on its own facts and circumstances and the matters set out in this practice note are intended as guidance and are not prescriptive.
- The Explanatory Memorandum (EM) to the Tax Agent Services Bill 2008 makes a number of references to how letters of engagement can be used and how they are relevant in the business of tax practitioners.
- For example, the EM suggests that the taxation rights and obligations that are relevant to a tax practitioner could be outlined in the letter of engagement between the tax practitioner and client. Advising a client of their rights and obligations under the taxation laws that are materially related to the tax agent services that a tax practitioner provides is one of the requirements in Code item 12 in the TASA (see paragraph 11).
- Further, there are other legal and professional standards and regulatory requirements under which letters of engagement may be necessary. Examples include standards and requirements of ASIC (in relation to tax (financial) advisers), the Accounting Professional and Ethical Standards Board (APES 305 Terms of Engagement) and the Auditing and Assurance Standards Board. In circumstances where tax practitioners are required by other legal, professional and regulatory requirements to provide similar disclosure documents to clients, the TPB does not expect tax practitioners to provide separate and distinct letters of engagement to clients (unless the tax practitioners consider it appropriate to do so).
- The TPB considers that an effective letter of engagement may assist tax practitioners in complying with the following principles of the Code, contained in section 30-10 of the TASA:
Code item 3 if you receive money or other property from or on behalf of a client and you hold the money or other property on trust, you must account to your client for the money or other property Code item 4 you must act lawfully in the best interests of your client Code item 5 you must have in place adequate arrangements for the management of conflicts of interest that may arise in relation to the activities that you undertake in the capacity of a registered tax agent, BAS agent or tax (financial) adviser Code item 6 unless you have a legal duty to do so, you must not disclose any information relating to a client’s affairs to a third party without your client’s permission Code item 7 you must ensure that a tax agent service that you provide, or that is provided on your behalf, is provided competently Code item 8 you must maintain knowledge and skills relevant to the tax agent services that you provide Code item 9 you must take reasonable care in ascertaining a client’s state of affairs, to the extent that ascertaining the state of those affairs is relevant to a statement you are making or a thing you are doing on behalf of the client Code item 10 you must take reasonable care to ensure that taxation laws are applied correctly to the circumstances in relation to which you are providing advice to a client Code item 12 you must advise your client of the client’s rights and obligations under the taxation laws that are materially related to the tax agent services you provide
- While the TPB considers that letters of engagement and similar agreements are an important step in ensuring compliance with these obligations, it is important to note that the existence of a letter of engagement of itself will not constitute compliance with any of the requirements or obligations under the Code and the TASA.
- For example, under Code items 9 and 10, tax practitioners are, in summary, required to take reasonable care in ascertaining a client’s state of affairs and to ensure that taxation laws are applied correctly. Whether or not a tax practitioner has taken reasonable care of any kind will be a question of fact to be answered by the circumstances of a particular situation. The existence of a letter of engagement will not on its own establish that reasonable care has been taken and these obligations cannot be transferred to the client.
- For further information on the Code, please refer to Explanatory paper TPB(EP) 01/2010 Code of Professional Conduct.
- The TPB considers that letters of engagement or similar agreements will be particularly beneficial in assisting tax practitioners to comply with the Code, when they cover the following matters (where relevant to the services being provided by the tax practitioner):
- the name and registration number of the tax practitioner that the client is appointing to perform the services. It is of advantage for the tax practitioner to identify the entity that, and/or the specific individuals who, will provide the tax agent service. This gives certainty to the client that the services will be performed by a person that is legally entitled to do so and is regulated under the TASA
- the identification of the client entities in relation to which the tax agent services are to be provided:
- tax agent services include ascertaining and advising on liabilities, obligations or entitlements of an entity in circumstances where the entity can reasonably be expected to rely on the services
- identification of the client entities for which services are to be provided clarifies the scope of the services as well as an understanding of the entities that may rely on the advice
- clarifying the client entities will also inform the tax practitioner about the entities to which information may be disclosed, having regard to the practitioner’s confidentiality and privacy obligations
- a description of the work that is to be performed, which may include a list of services and work that is expressly excluded from the engagement (including work completed by other parties/professionals not associated with the tax practitioner):
- a clear agreement as to the scope of the work to be performed limits the risk of misunderstandings between the client and the tax practitioner and assists in an understanding and agreement on the time frames, and respective responsibilities
- it also assists in an understanding that the scope of the work to be performed is within the practitioner’s competency and experience
- the tax practitioner’s and the client’s responsibilities under the engagement, for example:
- the client’s responsibility to make all relevant information available to the tax practitioner in a complete and timely manner
- the client’s responsibilities as a taxpayer under the taxation laws and the consequence of errors and omissions from the information given to the Australian Taxation Office (ATO)
- the tax practitioner’s responsibility to provide the services in a competent and timely manner
- the letter may provide that the tax practitioner may seek clarification of some matters where there is a need to do so, but that the tax practitioner will not audit the information provided by the client as the tax practitioner is satisfied that the client understands their record keeping obligations and is aware of the consequences of not keeping adequate records
the tax practitioner’s responsibility to take reasonable care to ensure that the taxation laws are complied with and that the tax practitioner may be liable for civil penalties for false and misleading statements made to the ATO
- the tax practitioner’s responsibility to lodge in a timely manner
- the form of any reports or other means of communication relevant to the tax agent services to be performed
- an explanation as to the extent to which the tax agent services can be relied upon and the limitation on other persons relying on the advice or on calculations contained in the report or advice
- the confidential nature of the communications between the client and the tax practitioner and that the tax practitioner will not disclose information relating to the client’s affairs to a third party without the client’s permission (unless the tax practitioner has a legal duty to do so). The letter of engagement may also be utilised by tax practitioners to clearly inform clients of any disclosures to third parties and obtaining the client’s permission in relation to such disclosures (for example, by a return signed letter of engagement or consent from the client), in order to satisfy the requirements of Code item 6 in the Code. For further information in relation to the client confidentiality requirements in the Code, refer to TPB Information Sheets TPB(I) 21/2014 Code of Professional Conduct – Confidentiality of client information and TPB(I) 32/2017: Code of Professional Conduct - Confidentiality of client information for tax (financial) advisers
- any arrangements for retention of the client’s documents or of making copies of them for the purposes of providing the services under the agreement or to secure payment of fees. For further information in relation to the TPB’s position relating to claiming liens over client property, refer to TPB Information Sheet TPB(I) 02/2011 Claiming a lien over client property
- the duty (under the TASA) of the tax practitioner to act lawfully in the best interest of the client, and to act honestly and with integrity
- situations in which the law overrides the duty of the tax practitioner to the client, such as compliance with notices under section 353-10 in Schedule 1 to the Taxation Administration Act 1953 concerning taxation laws, withholding tax obligations and any other duties of the tax practitioner under the TASA (including the Code)
- adequate arrangements the tax practitioner has in place for the management of conflicts of interest that may arise in relation to the activities undertaken in the capacity of a tax practitioner
- the rights and obligations of the client under the taxation law. For example, if the agreement extends to the preparation and lodgement of taxation returns, the agreement could advise the client of the self-assessment system and of the rights of objection and appeals. The letter of engagement might also be useful to describe the nature of the rulings system and that the client will be advised where the returns have been prepared in reliance on binding rulings issued by the Commissioner of Taxation (note however this may not be appropriate in all situations when considering factors such as the client and the costs involved in producing the extra information)
- the basis on which fees are to be calculated and charged, the frequency of billings and the time frame for payment. As disputes about fees often arise, the letter of engagement can limit the capacity for misunderstandings and provide the client with clear expectations about the amount that the tax agent services are likely to cost
- in relation to tax agents, how the tax agent will deal with any tax refund the tax agent receives on behalf of the client and whether the client consents to fees being deducted from a refund
- how the tax practitioner will deal with funds or other property held on trust for the client
- the details of any limitation of liability of the tax practitioner for work performed under the engagement and the legal basis for the limitation if it is a feature of the law of the jurisdiction in which the tax practitioner practises
- the client’s responsibility to advise the tax practitioner of changes in any matter that is relevant to the services that are to be provided by the tax practitioner
- the professional indemnity insurance arrangements the tax practitioner has in place
- the requirements of both the tax practitioner and the client in relation to terminating the engagement, including notice periods, finalisation of payment and invoicing matters, and the return of documentation and other property to the client
- the mechanisms available for resolving any disputes that arise between the client and tax practitioner, including internal dispute resolution arrangements and making complaints to the TPB.
- Separate letters of engagement should be issued for each client in receipt of your services, unless it is agreed otherwise. For example, separate letters should be issued if you provide tax services to both:
- a husband and wife
- a partnership and the individual partners
- a company and its shareholders
- a company and its directors (if providing services to the directors separately from the company)
- the trustees of a trust and its beneficiaries.
- In relation to recurring or ongoing engagements, the TPB recommends that arrangements are reconfirmed or reviewed with clients regularly (preferably annually). Further, the TPB would generally expect that a new letter of engagement or similar agreement is provided to clients in certain circumstances, including but not limited to the following:
- there is reason to believe that the client has misunderstood the terms and scope of the engagement
- there has been a significant change to the client’s relevant personal circumstances
- there are changes in the terms or scope of the engagement
- there is a change to the management, ownership and or structure of the client (particularly relevant to corporate entities and clients that are part of a corporate group)
- there is a change in the nature or size of the client’s business
- there is a change in any relevant or applicable laws or regulations
- there has been a change to the third party recipients of client information (which requires prior client consent in accordance with Code item 6 of the Code).

- While the TPB does not consider it appropriate to provide template or example letters of engagement or similar agreements for tax practitioners, the TPB understands that many TPB recognised professional associations offer such templates or examples to their members. The TPB welcomes the use of examples and templates by tax practitioners, however, the TPB considers that it is important for tax practitioners to use their professional judgement in considering the matters that are addressed in their letters of engagement, beyond or in contrast to the matters set out in any examples or templates they are utilising, having regard to their practice and their engagement with each client.
