Tax Agent
A registered professional authorised by the Tax Practitioners Board to prepare and lodge tax returns on behalf of clients.
A registered tax agent is a professional who is authorised by the Tax Practitioners Board (TPB) to provide tax advice, prepare tax returns, and deal with the ATO on your behalf. Using a registered tax agent gives you an extended lodgement deadline — typically until 15 May the following year, compared to 31 October for self-lodgers. Their fees are also tax-deductible in the year you pay them.
Tax agents must meet qualifications requirements (typically a degree in accounting or tax law), pass a fit-and-proper-person test, maintain professional indemnity insurance, and complete ongoing continuing professional education. You can verify whether someone is a registered tax agent on the TPB website (tpb.gov.au).
Using a tax agent is advisable if you have complex tax affairs such as rental properties, capital gains events, business income, foreign income, or if you want to maximise your deductions. Be wary of unregistered preparers who may offer cheap services — they are not legally allowed to charge a fee for preparing your return, and you have no consumer protections if something goes wrong.
How it works
A registered tax agent is a professional authorised by the Tax Practitioners Board to prepare tax returns, give tax advice, and deal with the ATO on your behalf. Registration isn't automatic — agents must meet qualification requirements, pass a fit-and-proper-person test, hold professional indemnity insurance, and keep up ongoing professional education, all of which you can verify by looking them up on the TPB's public register before engaging them.
The most visible practical benefit is the lodgement deadline: self-lodgers must submit by 31 October, but if you're registered with a tax agent by that date, your effective deadline typically extends well into the following year, usually around 15 May. Their fees are also fully tax-deductible in the year you pay them, which softens the cost of using one, and they act as your point of contact if the ATO has questions about your return.
The risk to watch for is unregistered preparers who aren't legally allowed to charge a fee for preparing returns and who offer no consumer protections if they get something wrong — if someone charges you for tax help but isn't on the TPB register, you have far less recourse than with a registered agent. A tax agent is generally worth the cost once your affairs go beyond a straightforward salary return: rental properties, capital gains events, business income, or foreign income are the classic triggers.
Example: the deadline difference a tax agent buys you
If you lodge your own tax return, it's due by 31 October following the end of the financial year. If instead you register with a tax agent before that date, your effective deadline for that year's return typically moves out to around 15 May the following year.
That's a gap of roughly six and a half months — from 31 October to 15 May — giving you far more breathing room to gather documents, especially if your income sources are more complicated than a single employer. The catch is that the extension only applies if you're on the agent's books before the normal 31 October deadline passes.
