Do you need a registered tax agent to lodge your tax return?

Nothing in Australian tax law requires you to use a tax agent to lodge your own income tax return. You are free to prepare and lodge it yourself, commonly through the ATO's online myTax service, at no cost beyond your own time. The requirement only kicks in on the other side of that transaction: anyone who charges a fee to prepare or lodge a tax return on someone else's behalf must be registered with the Tax Practitioners Board as a tax agent. So the real question is not whether you are allowed to self-lodge, but whether doing so, versus paying a registered agent, suits your situation.

Deadlines are one of the more practical reasons people choose to use a registered tax agent. For a self-lodged individual return, the standard deadline is 31 October each year; for the 2025-26 financial year specifically, 31 October 2026 falls on a Saturday, so the practical deadline shifts to Monday 2 November 2026. Miss that date without lodging or making other arrangements, and penalties can start to apply.

Engaging a registered tax agent can extend that deadline considerably, but only under specific conditions. You generally need to be formally added to the agent's client list with the ATO before 31 October, and you must not have any prior-year returns still outstanding as at 30 June of that year — if you never lodged an earlier return, the extension does not apply. Meet those conditions, and many individual lodgments can be pushed out as late as 15 May of the following year, with a further concession to early June if any tax owed is paid by then. This is a genuine practical advantage for people who are busy, disorganised, or simply want more time, though it depends on engaging the agent well before the standard deadline rather than at the last minute.

Beyond deadlines, a registered tax agent brings professional accountability that self-lodging does not. Registration with the Tax Practitioners Board requires meeting qualification and experience standards, holding professional indemnity insurance, and being a fit and proper person under the Board's rules. Registered agents are also subject to a code of conduct and can face disciplinary action, including deregistration, for serious breaches — a layer of accountability that simply does not exist when you lodge your own return or use someone who is not registered.

That accountability cuts both ways: it also means you can check it. The Tax Practitioners Board maintains a public register that lets you search for a practitioner by name and confirm they are currently registered, and for what scope of services. This is a reasonable step to take before engaging anyone you are paying to lodge a return on your behalf, since using an unregistered preparer who charges a fee is not something either of you is legally permitted to do, and it removes the accountability that registration is meant to provide.

Whether self-lodging or using a registered agent suits you better depends on how complex your return is, how much time you have, and how confident you are navigating myTax on your own. Straightforward returns with standard employment income are often manageable to self-lodge; anything involving business income, multiple income streams, rental property or capital gains is where a registered agent's experience commonly earns back more than their fee, simply by getting things right the first time.

For anything specific to your own return, checking directly with a registered tax agent or the ATO is the reliable path.
