The word “accountant” is not a protected title in Australia. It is used by a wide range of people, and the title on its own tells a reader very little about who is regulated and who is not. What the law regulates is not the title but the work. Under the Tax Agent Services Act 2009, a person who provides tax agent services for a fee or other reward must be registered with the Tax Practitioners Board, unless an exemption applies.
That distinction is the foundation for everything that follows in this guide. A reader who begins with registration is checking the one thing the law actually controls, rather than the impressions a website, an office or a warm referral can create. Registration is also the easiest filter to apply, because it does not call for judgement. The register is public, the search takes minutes, and the answer is a matter of record rather than opinion. It is the first check in the order this guide sets out, and every later check assumes it has been passed.
No title should be accepted in place of it. A person may describe themselves as an accountant and still not be registered to carry out the work being offered, and where that work is the provision of tax agent services for a fee, the absence of registration is a decisive problem, not a detail. A title on its own is only a claim. Registration is a verifiable fact, and it is the first check a reader should run, ahead of qualifications, reputation and price.
A registered tax agent may provide the full range of tax agent services. That range includes preparing and lodging income tax returns, giving tax advice and dealing with the Commissioner on a client's behalf. For most readers this is the person who prepares the annual return and who answers for it if the Australian Taxation Office queries what has been lodged.
A BAS agent's registration is narrower. It covers BAS services only: business activity statements, instalment activity statements and the tax obligations those forms address, together with advice about them. The scope of a BAS agent's registration does not extend to preparing and lodging income tax returns, so a reader who needs a return lodged requires a tax agent, not a BAS agent. A business whose needs are confined to activity statements and the obligations those forms deal with may be served by a registered BAS agent.
The title “accountant” sits alongside these two categories but is not one of them. An individual or a business may use the title without holding tax agent registration, and may lawfully carry out work that does not require registration, such as bookkeeping, management reporting and some advisory work. The line is drawn by the work rather than the name. If the work includes preparing and lodging a tax return for a fee, the person doing it must be a registered tax agent, whatever they choose to call themselves.
Registration itself is not a formality. An applicant must satisfy qualification and experience requirements and pass a fit-and-proper-person test before registration is granted. Once registered, an agent must comply with a code of professional conduct and meet ongoing requirements, including continuing professional education and, for those in public practice, professional indemnity insurance. These conditions are enforced and are conditions of remaining registered, which is why registration carries a weight that a claimed skill cannot.
The Tax Practitioners Board maintains a public register of tax agents and BAS agents. The register of tax practitioners on the Tax Practitioners Board website is the authoritative place to confirm that an agent is currently registered, and the check belongs before the first meeting rather than after it.
The search is straightforward. The reader searches the name, notes the registration type recorded, tax agent or BAS agent, and confirms that the record is current. Where a firm is being engaged, the same check is run against the firm itself, because a company or partnership that provides tax agent services must itself be registered with the Board.
Two findings end the process here. A name that cannot be found on the register is not explained away by a busy practice or a recent change of name, and a registration type that does not match the work offered, such as a BAS agent offering to lodge an income tax return, is a mismatch that no fee structure or recommendation can repair. When either finding appears, the reader has the answer they came for, and no further check is needed. The check takes minutes, and it is worth running even when the agent has been recommended by someone the reader trusts.
Many tax agents also hold membership of a professional accounting body. The bodies most commonly encountered in Australia are Chartered Accountants Australia and New Zealand, CPA Australia and the Institute of Public Accountants. Membership is voluntary, and that is the first thing to understand about it.
The signal membership sends is genuine. A member has met that body's entry standards, follows its code of ethics and meets its continuing professional development requirements, and is subject to the body's complaints and discipline processes. For a reader weighing two otherwise similar candidates, these are meaningful points of difference, and they are worth noting on a shortlist.
Membership does not, however, take the place of registration. The two answer different questions. Registration answers whether the person may lawfully provide tax agent services; membership answers whether the person also belongs to a voluntary body with its own standards. A reader should never accept the answer “I am a CPA” in response to the question “are you a registered tax agent”. The register, not the letterhead, is the document that settles the matter.
This guide does not rank the professional bodies, and the reader does not need to. Each body sets its own entry and ongoing requirements, and a membership held in good standing is a supporting signal whichever body issued it. The registration check comes first, and the membership is weighed after that check has passed, never before it.
Fee structures vary from one practice to another, and the terms of an engagement are a matter for agreement rather than assumption. Before engaging, a reader should ask how the annual return is charged. Some practices quote a fixed fee for the job; others charge by the hour. The point is not that one model is better than the other, but that the reader knows which model applies before the work begins.
The second question is what the fee includes. Preparation and lodgement of the return may be covered, or they may be only part of the picture. The reader should ask whether dealing with an enquiry or an amendment from the Australian Taxation Office is included, whether advice given during the year is covered, and whether business activity statement and instalment activity statement work is priced separately where it applies. The reader should also ask what triggers additional work and a fresh quote, and whether GST is added on top of the quoted figure.
A fee quoted without its inclusions is not yet a fee the reader can compare, and the fee arrangement should be put in writing before the first engagement. A written arrangement records the scope alongside the price and becomes the reference point if a later invoice differs from the earlier conversation. A practitioner who is reluctant to set those terms out in writing has given the reader a reason to pause before any documents are handed over; an arrangement that names the inclusions, the exclusions and the point at which a fresh quote applies is the clearest protection the reader has.

Registration answers who may do the work. It does not answer who does it well, and that second question turns on whether the practice matches the reader's circumstances. Those circumstances vary widely: a salary or wage earner whose income is reported through pay as you go withholding, a sole trader, an investor with a rental property, a small business with employees, a trust or a company, income from overseas, income from crypto assets, or a prior-year problem such as an amendment or a notice from the Australian Taxation Office. Each of these places different demands on the person preparing the return.
Before engaging, ask how much of the agent's work sits in the reader's situation. The useful answer is specific, clients in the same kind of work, rather than a general assurance that the practice handles everything. Ask who actually prepares the return, because the person who takes the engagement is not always the person who does the work, and ask who reviews it before lodgement. Ask what software the practice uses and how records are exchanged.
Experience with the specific situation matters more than the age or the size of the firm. A large practice may carry deep experience in an area the reader does not need, while a small practice may do little else but the reader's kind of return. The test is the match, and the match is established by asking rather than assumed from the letterhead. The match does not require the reader to become a tax specialist; it requires the agent to speak to the reader's own circumstances in plain terms.
A first meeting is productive when the reader arrives prepared. The documents to bring are ordinary ones: payment summaries or income statements, bank and interest statements, receipts for the deductions the reader intends to claim, and the notice of assessment from the prior year where one exists. Where the reader's affairs involve a business, a trust or a company, the relevant documents belong in the folder as well, including any ABN record, trust deed or company documents.

The questions for the meeting are equally plain. Who prepares the return, and who reviews it before lodgement? How does the reader reach the agent during the year, and who responds when the usual contact is away? When will the return be lodged? What happens if the Australian Taxation Office reviews or audits the return? How are amendments to a lodged return handled? The manner of the answers carries weight as well. An agent who answers directly, without impatience, and who asks questions back about the reader's affairs is demonstrating how the engagement will work.
A clear first meeting ends with the reader knowing exactly what to send, what it will cost and when it will be done. If any of those three remains unclear when the meeting closes, that is the question to raise before leaving the room.
A practical way to begin is to build a shortlist first, and to run every check in this guide on whoever makes it. One sensible starting point is a local directory, where accountants and tax agents listed in a local directory appear with their services and contact details together, which makes the first pass of comparison straightforward.
From there the reader compares on the points that matter. Firms already listed in a local directory can be checked for the services they state, the registration they claim and whether they are close enough for the reader to deal with an accountant in person rather than over the phone alone. A shortlist built this way is only a starting point; none of the checks in this guide is skipped because a name came from a directory.
The register is the first test for every name on the list, including a chartered accountant or any other practitioner holding a professional designation. No designation changes the order of the checks, and no recommendation should shorten them.
The checks in this guide are brought together in the list below. A reader who can answer every line from the register, from the fee discussion and from the first meeting has completed the process this guide recommends. A line that cannot be answered is itself a finding, and it is better made before an engagement begins than after one.
The list is not a test of an agent's patience. It is the ordinary care that engaging a professional involves, and an agent who welcomes it is showing the reader how the working relationship will feel.
Choosing a tax accountant is an order of checks, and the order is deliberate. Registration with the Tax Practitioners Board is the gate, because it is the one requirement the law places on the work itself. Professional body membership is a supporting signal, worth noting and never sufficient on its own. The fee and the scope of the engagement are agreed in writing before the first return is prepared, so that the price and the inclusions are both on the record. And the agent's experience with the reader's own situation is confirmed before lodgement, so that the return is prepared by someone who has done that work before.
None of these checks guarantees a perfect outcome, because no engagement can. They are the protections a reader can actually control: the registration itself, the written fee arrangement and the fit with the reader's own affairs. Worked through in order, they are the whole process, and they are complete before the first return is ever lodged.
