Best Tax Lawyers in Australia
Updated 22 September 2026
Compare tax lawyers in Australia by city, and check your deadline first: under section 14ZW of the Taxation Administration Act 1953 (Cth), most individuals and small businesses have 2 years from the notice of assessment to object to the ATO, and other taxpayers have 4 years. Tax lawyers run ATO audits and objections, appeal objection decisions to the Administrative Review Tribunal (ART) and the Federal Court, and advise on tax structuring.
Before you contact a tax lawyer, collect the notice of assessment or ATO decision, any audit or position paper, your returns and the working papers behind them. Note the date each ATO notice was given, because every stage of a tax dispute runs from service of the previous decision. The lists below are ordered using the method explained in how we rank law firms.
What does a tax lawyer do?
A tax lawyer (or tax dispute lawyer) is a solicitor who advises on tax law and represents taxpayers against the ATO or state revenue offices. Typical tasks are:
- Respond to ATO audits, reviews and information notices.
- Draft objections to assessments and private rulings.
- Apply for review of objection decisions in the ART.
- File and run tax appeals in the Federal Court of Australia.
- Negotiate settlements with the ATO.
- Advise on voluntary disclosures before the ATO starts an audit.
- Structure transactions, trusts and business sales for tax purposes.
- Advise on state taxes such as payroll tax, land tax and duty.
- Represent clients in tax fraud investigations and prosecutions.
When do you need a tax lawyer?
You need one when the ATO has started a formal process, when large amounts are at stake, or when you want advice to stay privileged.
When the ATO starts an audit or review
Early advice shapes what you tell the ATO and how you frame the facts. Legal advice obtained at this stage can be protected by privilege, while an accountant's advice generally cannot.
When you disagree with an assessment
An objection must be lodged within the section 14ZW time limit. The objection sets the grounds, and under Part IVC you are generally limited to those grounds in any later review or appeal unless the ART or court allows otherwise. You also bear the burden of proving that the assessment is excessive or otherwise incorrect, and what it should have been (s 14ZZK).
When the objection is disallowed
You can apply to the ART or appeal to the Federal Court, each within 60 days after the objection decision is served.
When the ATO alleges fraud or evasion
Serious matters can lead to extended amendment periods, penalties and criminal referral. A lawyer can advise before any interview with investigators.
How does an ATO tax dispute work?
An ATO tax dispute follows a fixed sequence of objection, review and appeal under Part IVC of the Taxation Administration Act 1953 (Cth).
| Stage | Time limit | Where | Cost (as at September 2026) |
|---|---|---|---|
| Objection | 2 years from the notice of assessment for most individuals and small or medium business entities; 4 years for others (s 14ZW) | ATO | No fee |
| Late objection | Lodge with a request for an extension of time; a refusal can be reviewed by the ART (s 14ZX) | ATO, then ART | No ATO fee |
| Review of objection decision | 60 days after the decision is served (s 14ZZC) | Administrative Review Tribunal | $1,195 standard fee; $119 if the tax in dispute is under $5,000 or for certain refusals |
| Appeal of objection decision | 60 days after the decision is served (s 14ZZN) | Federal Court of Australia | Court filing fees apply |
The ART replaced the Administrative Appeals Tribunal on 14 October 2024, so older guidance that refers to the AAT now applies to the ART. The ART hears tax cases in private if the applicant asks (s 14ZZE). Lodging an objection or appeal does not stop the ATO from collecting the tax while the dispute runs.
Tax lawyer vs tax agent or accountant: what is the difference?
A tax lawyer gives legal advice and represents clients in disputes, while a registered tax agent prepares returns and gives tax agent services for a fee.
| Point | Tax lawyer | Tax agent or accountant |
|---|---|---|
| Regulator | State legal profession regulator; practising certificate | Tax Practitioners Board register |
| Main work | Disputes, objections, litigation, structuring advice | Returns, BAS, bookkeeping, compliance |
| Client legal privilege | Yes, for confidential legal advice (Evidence Act 1995 s 118) | Generally no |
| Represents you in the Federal Court | Yes | No |
Many disputes use both. The accountant supplies the figures and the lawyer runs the dispute, so the privileged advice stays with the lawyer.
How much does a tax lawyer cost?
Tax lawyers in Australia typically charge between $400 and $1,000 or more per hour plus GST, and senior tax partners and counsel charge more. These are market estimates, not official rates, and they vary by firm and matter.
| Matter | Typical fee model | Typical range (estimate) |
|---|---|---|
| Initial advice | Fixed fee or hourly | $500–$3,000 |
| Objection | Fixed fee or hourly | $3,000–$20,000 |
| ART review | Hourly | $15,000–$80,000+ |
| Federal Court appeal | Hourly | $80,000+ |
In NSW, Victoria and Western Australia, section 174 of the Legal Profession Uniform Law requires your lawyer to disclose the basis of costs and an estimate of total costs at the start. The guide How Much Does a Lawyer Cost in Australia? compares fee models across practice areas.
How to choose a tax lawyer
Use checks you can verify:
- Practising certificate. Confirm a current certificate on the state law society or regulator register.
- Specialist accreditation. Accreditation areas differ by state, so check the law society's register. What Is an Accredited Specialist Lawyer? explains the schemes.
- Dispute experience. Ask how many objections, ART reviews and Federal Court appeals the lawyer has run, and for which taxes.
- Advisory or controversy focus. Structuring lawyers and dispute lawyers are often different people in the same firm. Ask who will run your matter.
- Written costs disclosure. Expect an estimate of total costs, including counsel's fees for any hearing.

Frequently asked questions
How long do I have to object to an ATO assessment?
Most individuals and small or medium business entities have 2 years from the notice of assessment, and other taxpayers have 4 years, under section 14ZW of the Taxation Administration Act 1953 (Cth). Some other decisions have a 60-day limit.
What happened to the AAT for tax disputes?
The Administrative Review Tribunal (ART) replaced the Administrative Appeals Tribunal on 14 October 2024. Tax objection decisions are now reviewed by the ART.
Do I have to pay the disputed tax while I object?
Generally yes. Part IVC of the Taxation Administration Act 1953 provides that a pending review or appeal does not stop the tax decision from being implemented, so the ATO can still collect the debt. A lawyer can advise on payment arrangements while the dispute runs.
Can I lodge an objection late?
Yes, by lodging the objection with a request for an extension of time. If the Commissioner refuses, that refusal can be reviewed by the ART, and the lower ART fee applies.
Is advice from my accountant privileged?
Generally no. Client legal privilege under section 118 of the Evidence Act 1995 protects confidential communications with a lawyer made for the dominant purpose of legal advice, so advice from a tax agent or accountant acting as such is not covered.
