- A Chartered Tax Adviser is a designation, not a licence to charge for tax work
- Only registered tax and BAS agents can charge a fee for tax agent services
- Check any adviser on the free TPB public register before you sign
- The ATO only allows a deduction for fees paid to a recognised tax adviser
If you are comparing quotes and trying to work out whether a chartered tax adviser australia businesses recommend is worth the money, start here. A Chartered Tax Adviser (CTA) is a designation awarded by The Tax Institute to tax professionals who pass its CTA3 Advisory exam and keep up ongoing tax CPD. It is not the same thing as being a registered tax agent, and in Australia only registered tax and BAS agents can legally charge a fee for tax agent services, which is the fact that should actually shape who you hire and whether you need a tax accountant service or something more specialised.

What is a chartered tax adviser?
A Chartered Tax Adviser is a member of The Tax Institute who has passed the CTA3 Advisory exam and met the Institute’s Fellow-level membership criteria. Holders use the post-nominal CTA.
The requirements behind it are real. To sit CTA3 Advisory you need 36 months of relevant Australian tax or tax law experience, and CTA3 sits at the end of a four-subject program (CTA1 Foundations, CTA2A Advanced, CTA2B Advanced, then CTA3 Advisory). Once you hold it, Chartered Tax Advisers must complete a minimum of 30 hours of structured tax-related CPD each year.
So the CTA designation Australia tax professionals pursue is a genuine specialist credential, and it is the closest thing the market has to a signal that someone does advisory work rather than compliance. What it is not is permission to do anything. That comes from somewhere else entirely.
Chartered tax adviser vs registered tax agent: what is the difference that matters?
One is a professional designation. The other is a legal licence. Almost nothing else on the first page of Google leads with this distinction, and it is the one that protects you.
The Tax Practitioners Board is the independent national body that registers and regulates tax agents and BAS agents under the Tax Agent Services Act 2009. The TPB states plainly that generally only registered tax and BAS agents can charge or receive a fee or other reward for providing tax agent, BAS or tax (financial) advice services. Section 50-5 of the TASA sets out that requirement; section 90-5 defines what counts as a tax agent service.
A CTA who is not TPB-registered cannot charge you to prepare and lodge your company tax return. A registered tax agent with no CTA after their name can. Our comparison of a tax accountant vs registered tax agent goes further into where those two roles sit.
Who can legally charge you for tax advice in Australia?
Only a registered tax agent or, within a narrower scope, a registered BAS agent. The TPB warns that there are severe penalties for anyone who provides tax agent services for a fee, advertises tax agent services, or represents themselves as a registered tax agent while unregistered.
There is a second consequence that hits your pocket rather than theirs. The ATO allows a deduction for fees paid to a recognised tax adviser in the year you incur them, and defines a recognised tax adviser as a registered tax agent, BAS agent, qualified tax relevant provider or legal practitioner. It also states you cannot claim for the cost of tax advice given by a person who is not a recognised tax adviser. Pay an unregistered adviser and you lose the deduction as well as the protection.
How do you check if someone is a registered tax agent?
Search the TPB public register, which is free and takes about 30 seconds. It is the single most useful thing in this article.
- Go to the TPB public register and search the individual’s name, or the practice’s name if you are being invoiced by a company.
- Confirm they appear as registered, and check the registration type: tax agent, BAS agent, or tax (financial) advice services.
- Read any conditions. The TPB can impose a condition limiting the scope of services someone may provide, or limiting them to a particular area of tax law, and the register displays it.
- Check the disciplinary record. The register also records Code of Professional Conduct breaches and sanctions.
Two practical notes. A company or partnership providing tax agent services must itself be registered, and must have a registered individual tax agent providing services on its behalf under supervisory arrangements, so check the entity on your invoice and not just the person you email. Separately, you will need to nominate your agent in ATO online services before they can act for you, a step that catches out most new clients. Our walkthrough on how to nominate your tax agent covers the sequence.

CA, CPA, IPA, CTA: what does each set of letters mean?
Here is the whole landscape in one table, with the only column that carries legal weight sitting in the middle.
| Credential | Issued or regulated by | What it legally permits | What it signals |
|---|---|---|---|
| Registered tax agent | Tax Practitioners Board, under TASA 2009 and TASR 2022 | Charging a fee for tax agent services, including preparing and lodging returns | Met statutory qualification, experience, fit-and-proper and PI insurance tests |
| Registered BAS agent | Tax Practitioners Board | Charging a fee for BAS services only, a subset of what tax agents may do | Bookkeeping and activity-statement competence |
| CTA (Chartered Tax Adviser) | The Tax Institute | Nothing by itself | Passed CTA3 Advisory, 36 months tax experience, 30 hours tax CPD a year |
| CA (Chartered Accountant) | Chartered Accountants ANZ | Nothing by itself | CA ANZ membership; principals in practice must also hold a Certificate of Public Practice |
| CPA | CPA Australia | Nothing by itself | CPA Australia membership; public practitioners need a public practice certificate |
| MIPA / FIPA | Institute of Public Accountants | Nothing by itself | IPA membership, SME focus; practitioners need an IPA Professional Practice Certificate |
Read that middle column again. Four of the six credentials permit nothing on their own, and they are the ones quoted hardest in a sales meeting. We cover CA vs CPA and public accountant vs chartered accountant separately.
Prefer a tax agent who answers the phone?

Do you need a chartered tax adviser, or is a registered tax agent enough?
For most businesses, a registered tax agent with relevant experience is enough. Asking do I need a tax adviser or an accountant is usually the wrong question, because the useful split is between compliance work and advisory work, not between job titles.
- Sole trader, one income stream, no employees. A registered tax agent or a BAS agent plus a tax agent at return time. CTA-level advice would be over-specified and you would be paying for it.
- Small Pty Ltd, straightforward structure. A registered tax agent who knows your industry. Ask about Division 7A if you draw money from the company, since that is where small companies most often go wrong.
- Company with a trust, or several entities. Worth having someone with genuine structuring depth in the room, whether or not they hold a CTA. Trust distributions and inter-entity loans are where cheap advice gets expensive.
- Cross-border ownership, restructures, an exit on the horizon. This is the situation where the CTA designation is a useful filter, because you want a specialist rather than a generalist.
Being blunt about it: the designation tells you about training, not about service. Whether someone answers the phone in November, explains a decision in plain English, or tells you about a problem before it becomes a lodgement is not something any set of letters predicts. TPB registration is the floor, not the ceiling.
What does tax advice cost, and what drives the price?
“How much do they charge to speak with them?” is one of the most common questions we hear on calls, and the honest answer is that the number depends far less on credentials than on how complicated your affairs are. The drivers, roughly in order of impact:
- How many entities you have. A company plus a trust plus a self-managed fund is three sets of accounts and three returns, not one.
- Whether there are trust distributions, and how many beneficiaries.
- Payroll and BAS frequency, since monthly reporting costs more than quarterly.
- Whether advisory work sits on top of compliance, or you only want the return lodged.
- Whether the engagement is fixed-fee or hourly. This is the one that determines whether you can predict the bill.
We have not put a price band in this article, because a range that covers a sole trader and a multi-entity group is useless to both. For actual figures see what a tax accountant costs in Australia.
When does specialist tax advice pay for itself?
When the amount at stake is bigger than the fee, which is a smaller threshold than most owners assume. Four situations recur:
- Division 7A. Money taken out of a company by a shareholder or associate without the right loan agreement becomes a deemed dividend. Getting this wrong is a tax bill on money you have already spent.
- Trust distributions. Resolutions have deadlines, and a defective one can push income back to the trustee at the top marginal rate.
- Restructures. Moving a business into a company or a trust can trigger CGT unless a rollover applies. Advice before the transaction is worth many times the same advice after it.
- Cross-border ownership. Residency, withholding and transfer pricing questions arrive together, and generalist compliance work will not surface them.
If you are the one becoming an agent rather than hiring one, the TPB aims to process complete applications within 30 days, though high volumes can push that to 60, and a newly registered agent must confirm how they meet the professional indemnity insurance requirements within 14 days of being notified.

FAQs on chartered tax adviser australia
Is a chartered tax adviser the same as a chartered accountant?
No, they come from different bodies and mean different things. A Chartered Tax Adviser holds a tax-specialist designation from The Tax Institute, while a Chartered Accountant is a member of Chartered Accountants ANZ, which is a general accounting body. Someone can hold both, one, or neither and still be a registered tax agent.
What is the difference between a tax agent and a BAS agent?
A registered tax agent can provide the full range of tax agent services, including preparing and lodging income tax returns and advising on tax positions. A registered BAS agent is limited to BAS services, which is a subset of what tax agents may do, covering activity statements and related GST and PAYG obligations. The TPB register shows which registration a person holds.
Is a bookkeeper allowed to lodge my BAS?
Only if they are a registered BAS agent or tax agent, or an exemption applies. Charging a fee for BAS services without registration is prohibited, so a bookkeeper who prepares your figures may need a registered agent to lodge. Ask for their TPB registration number and check it.
Do I need a CTA if I only have one company?
Almost certainly not. A single trading company with a simple share structure is well served by a registered tax agent who understands your industry, and the specialist premium is better spent when a trust, a restructure or cross-border income enters the picture. Revisit the question when your structure changes rather than at your next renewal.
What happens if my adviser isn't registered?
You lose two things: the legal protection that comes with a regulated practitioner, and your deduction for the fee, because the ATO only allows a claim for advice from a recognised tax adviser. You can report unregistered activity to the TPB, which investigates and can act on it. Checking the register first avoids the situation entirely.
