You confirm that you, and any other person you nominate in writing from time to time (provided we have acknowledged such nomination), are authorised to give us instructions and information on behalf of all persons we are acting for and to receive our advice and documents on their behalf.
If we are acting for a business, and we receive conflicting advice, information or instructions from different persons, we may refer the matter to the board of directors, partners or proprietors (as applicable) and act only as requested by them.
We will advise you and your spouse or partner on the basis that you are a family unit with shared interests. We may deal with either of you and may discuss with either of you the affairs of the other. If you wish to change these arrangements, please let us know.
We may be required to verify your identity for the purposes of the anti-money laundering laws. We may request from you such information as we require for these purposes and make searches of appropriate databases.
You must provide us with all information necessary for dealing with your affairs including information which we reasonably request, in sufficient time to enable our services to be completed before any applicable deadline. We will rely on such information being true, correct and complete and will not audit the information except to the extent we are specifically engaged to provide audit-related services.
You authorise us to approach such third parties as may be appropriate for information that we consider necessary to deal with your affairs.
You must keep us informed on a timely basis of changes in your circumstances that may affect our services.
You are further responsible for retaining paperwork for as long as legally required. You have obligations under self-assessment to keep full and proper records in order to facilitate the preparation of accurate returns.
Accordingly, any advice given to you is only an opinion based on our knowledge of your particular circumstances.
You must retain paperwork for a period of five years after the assessment as you may be subject to an Australian Tax Office review.
You are responsible for checking the assessment before submission to ensure accuracy.
To the extent our services involve the performance of services established by law, nothing in the engagement letter or these terms reduce our obligations under such law.
You must not act on advice given by us on an earlier occasion without first confirming with us that the advice is still valid.
Our services are limited exclusively to those you have engaged us to perform. Unless otherwise specified in the engagement letter, our services cannot be relied upon to disclose irregularities and errors, including fraud and other illegal acts, in your affairs. Neither an audit nor a review will be conducted and, accordingly, no assurance will be expressed.
Where our engagement is recurring, we may amend our engagement letter and these terms where we consider it is necessary or appropriate to do so. If you do not accept such amendments, you must notify us promptly in which case you may terminate our engagement in accordance with section 18 below and those amendments will not apply prior to such termination.
We will endeavour to record all advice on important matters in writing. Advice given verbally is not intended to be relied upon unless confirmed in writing. If we provide verbal advice (for example during a meeting or telephone conversation) that you wish to rely on, you must ask us to confirm the advice in writing.
We will not provide you with investment or financial advice regulated under the Corporations Act 2001 (Cth) unless we have expressly agreed to do so in writing, specifying an applicable Australian Financial Services Licence number.
We are obliged to consider whether our clients create any threats to compliance with our Fundamental Principles and where we cannot reduce the risk to an acceptable level we are obliged to cease the engagement under the Code (section 320) to decline or cease the client engagement.
We have a duty to act in your best interests, unless this duty is inconsistent with our duty to act in the public interest.
We will comply with the professional and ethical standards of the Accounting Professional and Ethical Standards Board, available at apesb.org.au. This includes APES 110 Code of Ethics for Professional Accountants (including Independence Standards), which among other things contains provisions that apply if we become aware of any actual or potential non-compliance with governing laws or regulations (NOCLAR). Where any such non-compliance poses substantial harm (such as serious adverse consequences to investors, creditors, employees, auditor, group auditor or the public), we may be required to disclose the matter to an appropriate authority.
We will inform you of your rights and obligations available under taxation law, including any rights that may be available to seek a private ruling and the lodging of objections and appeals against adverse positions adopted by revenue authorities. We will also inform you of any possible penalties and other legal tax consequences to enable you to make an informed decision.
We are responsible for maintaining records for a period of at least five years unless otherwise required by legislation.
We will inform you if we become aware of any conflict of interest in our relationship with you (including between the various persons this engagement letter covers) or in our relationship with you and another client. Where conflicts are identified which cannot be managed in a way that protects your interests then we will be unable to provide further services to some or all of the persons to whom this engagement applies. If this arises, we will inform you promptly.
We may act for other clients whose interests are not the same as or are adverse to yours, subject to the obligations of conflicts of interest and confidentiality referred to above.
Our fees will be charged on the basis set out in the engagement letter and have been set based on the level of skill, responsibility, importance and value of the advice, as well as the level of risk.
If we have provided you with an estimate of our fees for any specific work, this is an estimate only and our actual fees may vary.
We may provide a fixed fee for the provision of specific services. If it becomes apparent to us, due to unforeseen circumstances, that a fixed fee is inadequate, we may notify you of a revised figure and seek your agreement to it.
In some cases, you may be entitled to assistance with your professional fees, particularly in relation to any investigation into your tax affairs by the ATO. Assistance may be provided through insurance policies you hold or via membership of a professional or trade body. Other than where such insurance was arranged through us, you will need to advise us of any such insurance cover that you have. You will remain liable for our fees regardless of whether all or part are to be paid by someone else.
We will bill monthly and our invoices are due for payment within 7 days of issue. Our fees set out in our engagement letter are exclusive of GST which will be added to our invoice where it is chargeable. Any disbursements and expenses we incur in the course of performing our services will be added to our invoices where appropriate.
Unless otherwise agreed to the contrary, our fees do not include the costs of any counsel, or other professionals or third parties engaged with your approval.
We may charge interest on late paid invoices at the rate of 10% above the RBA cash rate. We may also suspend our services or to cease to act for you on giving written notice if payment of any fees is unduly delayed. We reserve the right to use a debt collection agency or other legal means to recover outstanding fees. If we incur any debt collection / fee recovery costs such as commissions, disbursements, and/or legal fees, such costs are payable by you.
We intend to exercise these rights only where it is fair and reasonable to do so.
If permitted by law or professional guidelines, we may exercise a lien over all materials or records in our possession relating to all engagements for you until all outstanding fees and disbursements are paid in full.
We will take all reasonable steps to keep your information confidential, except where:
We may retain your information during and after our engagement to comply with our legal requirements or as part of our regular IT back-up and archiving practices. We will continue to hold such information confidentially.
We may mention that you are a client for promotional purposes.
You must make all necessary notifications and obtain any necessary consents for us to process personal information you provide to us. We collect and use that personal information for the purposes of providing the services described in the engagement letter to you and we will comply with the Privacy Act 1988 (Cth) when processing that personal information. Our privacy policy provides further details of our privacy practices.
We own the copyright and all other intellectual property rights in everything we create in connection with this engagement. Unless we agree otherwise, anything we create in connection with this agreement may be used by you only for the purpose for which you have engaged us.
Our liability is limited by a scheme approved under Professional Standards Legislation. The scheme facilitates the improvement of professional standards to protect consumers and may limit our liability to you in cause of action.
The scheme applies to professional accounting services including accounting, bookkeeping, taxation, audit and assurance, insolvency and corporate reconstruction, management accounting, management consulting, forensic accounting, and valuation services.
You agree not to bring any claim against any of our principals, shareholders or employees in their personal capacity.
To the maximum extent permitted by law, we are not liable to you for:
Our advice and information is for your sole use, and we accept no responsibility to any third party, unless we have expressly agreed in the engagement letter that a specified third party may rely on our work.
Each of us may terminate this agreement by giving not less than 21 days’ notice in writing to the other party except where a conflict of interest has arisen, you fail to cooperate with us or we have reason to believe that you have provided us or any other person with misleading or factually inaccurate information, in which case we may terminate this agreement immediately. Termination will not affect any accrued rights.
You must advise of any changes to your contact details. We may send any communications to the last contact details you have provided. Unless you instruct us otherwise we may, where appropriate, communicate with you and with third parties via email or by other electronic means. The recipient is responsible for virus checking emails and any attachments. There is a risk of non-receipt, delayed receipt, inadvertent misdirection or interception by third parties in any form of communication, whether electronic, postal or otherwise. We are not responsible for any such matters beyond our control.
Our engagement is governed by New South Wales law. The courts sitting in that State will have non-exclusive jurisdiction in relation to any dispute between us.
If any provision of the engagement letter or these terms is void, that provision will be severed and the remainder will continue to apply. If there is any conflict between the engagement letter and these terms, these terms prevail.
If you have any concerns about our costs or services, please speak to the person responsible for this engagement, who is identified in our engagement letter. To resolve your concerns we have policies and procedures in place to deal appropriately with complaints and will use best endeavours to resolve a complaint or dispute to the mutual satisfaction of the parties involved. We may require you to detail your complaint in writing to allow us to fully investigate any concerns that you raise.
We may utilise cloud computing service providers, including:
other third parties from time to time and as separately notified to you.
To perform the services, we may provide these third parties with access to your data to the extent this is required to perform the services.
Your data will be stored in accordance with the security practices of the third party service provider and our Privacy Policy.
You may consent for an Accredited Data Recipient under the Consumer Data Right (CDR) to disclose your CDR data to us. You may nominate us as your Trusted Adviser for this purpose. As your Trusted Adviser, we will only access the data necessary to provide the services in this engagement letter.
Chartered accountants and registered tax agents in Sydney CBD, advising individuals, families and businesses on tax, accounting and structure.
We work directly in your accounting file, in whichever package suits your business.
A sale, a restructure, an ATO letter, or a decision you want checked before you make it. A few lines in your own words is enough.
A little detail helps us quote accurately: the number of entities, any years outstanding, and the state of your records.
{{ p.t }}
We can quote separately for anything excluded. We won’t do or bill work outside the agreed scope without your approval.
Sending these at the start is the best way to get the work done quickly. The checklists set them out in full.
We quote a fixed fee in writing before work starts. Complex structures, catch-up years and multiple entities cost more, and we’ll tell you before we begin.
What to gather before your appointment.
Four free checklists, no sign-up needed. Sending everything together means your return can be finished in days rather than weeks.
Notes on common tax questions.

Every engagement is scoped and priced in writing. The fees below are starting points, and the estimator gives a closer figure for your situation. Advisory and structuring work varies too much to list, so we quote it per engagement.

A Sydney practice since 1974.
Tsia Partners is a Sydney chartered accounting and tax practice working with individuals and businesses across Australia. We handle the annual compliance work and advise on the decisions around it. We have kept the practice small so a principal stays responsible for your work.
Many clients have been with us for decades, through business sales, family changes and the occasional ATO review.
The practice began in 1974 as L K Tsia Chartered Accountants, founded by Loi Kah Tsia. Tsia Partners was formed in 2019 to continue that work, led by Jia Hao Tsia.
Tom was born in Sandakan, Sabah, in 1947. He grew up in Malaysia and came to Australia on his own to study. After qualifying as a Chartered Accountant he worked in other firms for several years, and in 1974, with the support of his wife, he opened his own practice, L K Tsia Chartered Accountants, in Sydney.
Over more than forty-five years he advised charities, unions and employer associations, manufacturers, family businesses and individuals. Many of those clients are still with the practice today.
He worked to three principles, and Tsia Partners still does:
The firm is now led by Jia Hao Tsia.
A small team who know your file.
The principles behind how we work.
Our office is in the Sydney CBD, with clients across NSW and interstate. We work the same way wherever you are.

We usually reply the same day.
A sale, a restructure, an ATO letter, or a decision you want checked before you make it. Write it in your own words.
A little detail helps us quote accurately: the number of entities, any years outstanding, and the state of your records.
Lodgement and payment deadlines for 2026–27.
Where a due date falls on a weekend it moves to the next business day, and we’ve shown the adjusted date. Clients on our tax agent list often have later due dates than those below.
These are general dates, not advice on your own obligations. Deadlines can differ for agent-lodged returns, new registrations and ATO concessions, so check with us before relying on one.
