Registered tax agents in Australia are licensed professionals who can legally charge a fee to prepare your tax returns, give you tax advice, and deal with the Australian Taxation Office on your behalf. They are licensed and policed by the Tax Practitioners Board (TPB) under the Tax Agent Services Act 2009, and anyone charging for tax work without that registration is breaking the law. For you as a client, the license is what unlocks a set of concrete protections: a code of conduct with real sanctions, mandatory professional indemnity insurance, extended lodgment deadlines, and a safe harbor if the agent makes a mistake.
What a Registered Tax Agent Can Do for You
Tax agents have the broadest scope of practice among tax practitioners. They can prepare and lodge income tax returns, fringe benefits tax returns, and other official statements for individuals, companies, trusts, and partnerships. They give advice on tax liabilities, help structure affairs to minimise tax within the law, and handle complex areas like capital gains tax and business restructuring.
They can also represent you directly in dealings with the Commissioner of Taxation. That covers responding to audits, negotiating payment plans for tax debts, and lodging formal objections to assessments you disagree with. When you are facing a dispute or compliance action, that advocacy role matters, because the agent knows how the ATO operates and can protect your rights during the process.
Tax Agents Versus BAS Agents
Tax agents are fully authorised to provide BAS (Business Activity Statement) services as well. BAS provisions include GST, wine tax, luxury car tax, fuel tax credits, pay-as-you-go withholding and instalments, and certain fringe benefits tax collection obligations.1Tax Practitioners Board. BAS Services Your tax agent can prepare and lodge your activity statements, set up accounting software with the correct GST codes, run payroll with Single Touch Payroll reporting, and deal with the ATO on any BAS-related matter.
A separately registered BAS agent can perform those same BAS services but cannot touch income tax. BAS agents cannot prepare income tax returns, give strategic tax advice, or handle capital gains tax matters. If a BAS agent starts advising you on income tax, they are operating outside their legal scope.1Tax Practitioners Board. BAS Services If your needs go beyond bookkeeping, payroll, and activity statements, you need a registered tax agent.
Extra Time to Lodge
One of the most tangible benefits of using a registered agent is extra time. If you prepare your own individual tax return, the deadline is 31 October each year. When you lodge through a registered agent, you gain access to the ATO’s registered agent lodgment program, which provides extended due dates that can push your deadline well into the following year depending on your circumstances.
The lodgment program sets specific due dates by entity type throughout the financial year. Taxable large and medium entities lodging through an agent have a 31 January deadline, and other entity types have their own scheduled dates spread across the year.2Australian Taxation Office. Registered Agent Lodgment Program 2025-26 – January 2026 The extensions only apply if you are genuinely engaged with a registered agent. Appointing one on the last day before the standard deadline without having provided your information will not protect you.
Safe Harbor if Your Agent Gets It Wrong
If your registered agent lodges something late or makes an error that triggers a penalty, you are not automatically on the hook. The safe harbor provisions shield you from certain administrative penalties when the fault lies with your agent rather than with you.
For a failure-to-lodge-on-time penalty, safe harbor applies if you can show two things: that you gave the agent all relevant tax information needed to lodge by the due date, and that the agent’s failure was not caused by their recklessness or intentional disregard of the law.3Australian Taxation Office. Failure to Lodge on Time Penalty The same logic applies to penalties for false or misleading statements made on or after 1 March 2010.4Australian Taxation Office. Safe Harbour
The burden of proof sits with you. “All relevant tax information” means everything needed to prepare and lodge on time in the approved form, including meeting any deadlines the agent set and providing signed documents when required. Keep records of when you handed documents over and any communications about deadlines. Without that evidence, safe harbor is just a theory.
Safe harbor does not cover every penalty. It does not apply to penalties involving tax avoidance schemes, and it does not apply to interest charges like the General Interest Charge or Shortfall Interest Charge. You can separately request remission of interest charges from the ATO, and they will consider factors like whether the delay was outside your control, your prior compliance history, and whether the situation was fair and reasonable.5Australian Taxation Office. Remission of Interest Charges Reliance on incorrect agent advice is not an automatic ground for remission, but the ATO treats it as a relevant circumstance when evaluating your request.
What the Registration Actually Guarantees
The TPB is the national regulator responsible for registering and overseeing tax agents, BAS agents, and tax (financial) advisers across Australia. It operates independently of the ATO, maintains a public register of all practitioners, and enforces the standards that agents must meet.6Tax Practitioners Board. Tax Agent Services Legislation Behind an agent’s registration number sit several concrete requirements.
The Code of Professional Conduct
Every registered agent is bound by a statutory Code of Professional Conduct set out in the Tax Agent Services Act 2009. The code contains 17 specific obligations organised across five categories: honesty and integrity, independence, confidentiality, competence, and other responsibilities.7Tax Practitioners Board. Code of Professional Conduct Breaching any of them can lead to sanctions ranging from written cautions to permanent deregistration.
Honesty provisions require agents to act with integrity, comply with tax laws in their own personal affairs, and properly account for any client money or property held on trust. Independence obligations mean agents must act in your best interests and manage conflicts of interest. Confidentiality rules stop them from disclosing client information to third parties without permission unless required by law. Competence obligations require agents to keep their knowledge current, take reasonable care to understand your circumstances, and correctly apply the law to the advice they give.7Tax Practitioners Board. Code of Professional Conduct
From 1 August 2024, the Tax Agent Services (Code of Professional Conduct) Determination 2024 added eight further obligations covering matters like avoiding false or misleading statements, managing conflicts in government dealings, keeping proper client records, implementing quality management systems, and keeping clients informed.7Tax Practitioners Board. Code of Professional Conduct
Professional Indemnity Insurance
Every registered agent must hold professional indemnity insurance. Letting a policy lapse is itself a breach of the code and can result in termination of registration. Minimum aggregate cover starts at $250,000 for agents with turnover up to $75,000 and scales to $1,000,000 for turnover above $500,000, with much higher minimums for agents providing tax (financial) advice services.8Tax Practitioners Board. Professional Indemnity Insurance The insurance exists to protect you if your agent makes a costly error.
Ongoing Education and Fit and Proper Review
Standard tax agents must complete at least 120 hours of continuing professional education across each three-year period, with a minimum of 20 hours in any single year.9Tax Practitioners Board. Continuing Professional Education Since 1 July 2024, registration itself is renewed annually for agents whose registration was granted or renewed from that date.10Tax Practitioners Board. Annual Registration From 1 July 2024 At each renewal, the TPB reassesses whether the agent remains a fit and proper person, looking at character, financial integrity, criminal history, and any tax defaults. A bankruptcy, a fraud conviction, or a pattern of personal tax non-compliance can all end a career.11Tax Practitioners Board. Fit and Proper Requirements
How to Check an Agent and Raise a Complaint
Before you hand over your tax affairs to anyone, check that they are actually registered. The TPB maintains a public register you can search online. It shows an agent’s registration status, any breaches of the Code of Professional Conduct, and any sanctions on the public record.12Tax Practitioners Board. Public Register If someone cannot be found on the register, they are not legally permitted to charge you for tax services.
If you believe a registered agent has acted improperly, the TPB accepts formal complaints through an online form. Before filing, the TPB encourages you to try resolving the issue directly with the practitioner in writing so you have a documented record of the dispute. The complaint form requires the agent’s name, address, and registration number, a description of what they were engaged to do, what went wrong, what evidence you have, and what outcome you are seeking. The form cannot be saved partway through, so gather everything before you start.13Tax Practitioners Board. Complaints Anonymous complaints are technically permitted, but the TPB will not progress them unless sufficient information and evidence are provided.
Why Using an Unregistered Preparer Is a Bad Idea
Operating as an unregistered tax agent is a serious civil offence. Under section 50-5 of the Tax Agent Services Act 2009, anyone who charges a fee for tax agent services while unregistered faces civil penalties of up to 250 penalty units for an individual ($82,500 at the current penalty unit value of $330) or 1,250 penalty units for a body corporate ($412,500). Even advertising tax agent services without registration attracts penalties of up to 50 penalty units for an individual ($16,500) or 250 penalty units for a body corporate ($82,500).14Tax Practitioners Board. Civil Penalty Provisions
The penalties apply per contravention, so someone who lodges hundreds of returns illegally can face penalties running into the millions. A recent case saw an unregistered preparer fined $1.8 million for lodging more than 3,300 returns over four years. From your side, an unregistered preparer is not bound by the code, carries no mandatory insurance, cannot access the lodgment program’s extended deadlines, and leaves you with no safe harbor if things go wrong. The register check takes a minute and is the single most useful step you can take before signing an engagement.
