Tax agent or DIY: what's right for your first Australian return

When DIY genuinely makes sense

If your situation is straightforward — one Australian employer for the full period, no overseas income, no ABN or contract work, standard work-related deductions you can substantiate, and no unusual events like selling an asset or receiving an inheritance — myTax through your linked myGov account is free, most of your income and bank interest pre-fills automatically, and the process typically takes well under an hour once your records are in order.

The ATO's own guidance and calculators are genuinely reasonably good for common, simple situations, and the system is built to be self-service for exactly this profile of taxpayer — it isn't a trap designed to catch people who should have used an agent.

DIY is also reasonable even in your first year specifically, contrary to the instinct that new arrivals should default to an agent purely because everything is unfamiliar — the mechanics of lodging a simple return are the same regardless of how long you've been here, and the ATO's guided myTax process explains most steps as you go.

When a registered tax agent earns their fee

Foreign income of any kind — even a small amount of overseas interest or a pension from a previous country — introduces the double-tax agreement and foreign income tax offset questions covered elsewhere in this series, which are genuinely easy to get wrong without specific knowledge of the relevant treaty.

Working holiday makers claiming DASP, or anyone with a mixed year across different visa-related tax rates (working holiday rate for part of the year, ordinary resident rate for the rest), benefit from an agent confirming the split is calculated correctly.

Any ABN or contract income alongside or instead of employee income changes the return meaningfully — you're managing your own withholding estimate, possibly GST, and different deduction rules apply.

Genuine uncertainty about your tax residency status — a borderline case where you're not sure whether you satisfy the resides test yet, or exactly when your residency started — is worth a professional read, since the date affects your tax-free threshold, Medicare levy position, and worldwide-income obligations all at once.

And simply feeling unsure, even about an apparently simple return, is a reasonable basis to use an agent in year one — the cost is modest relative to the value of confidence that you've done it correctly, and it's generally tax-deductible the following year regardless.

Checking an agent is actually registered before you engage them

Only individuals and firms registered with the Tax Practitioners Board (TPB) are legally permitted to charge a fee for preparing or lodging your tax return — using an unregistered preparer isn't just a quality risk, it can affect your legal protections if something goes wrong with the return.

The TPB maintains a free public register at tpb.gov.au — search by the practitioner's name, business name, or registration number to confirm they're currently registered (not suspended, not deregistered) before you hand over any personal or financial information. This takes about a minute and is worth doing even for an agent recommended by a friend or found through a migrant community group, since registration status can lapse or change.

A registered agent operating legitimately will have no issue with you checking — it's a completely normal and expected step, not an implied insult, and reputable agents often display their registration number on their own website or invoices for exactly this reason.

What a tax agent actually costs, as at 2026

For a straightforward individual return — salary and wage income, standard deductions, no business or investment complexity — typical fees sit roughly in the $100 to $280 range at the lower end, with many individual returns falling in a broader $100 to $400 band depending on complexity and location; fees in major cities can run somewhat higher, sometimes $250 to $500 for a straightforward return, reflecting local cost differences.

More complex returns — foreign income, ABN/contractor income, rental property, multiple income sources, DASP claims — cost more, and it's reasonable to ask for an estimate before engaging, since most registered agents will give one once they understand roughly what your return involves.

The fee itself is generally tax-deductible in the following year's return, which softens the net cost somewhat — worth remembering when comparing the headline fee against doing it yourself for free.

A practical way to decide

If you can honestly describe your year as 'one job, one country, straightforward pay' — DIY through myTax is a reasonable, free, and genuinely workable choice, and plenty of long-term Australian residents in exactly that situation do their own return every year without issue.

If any of the following apply, get a registered tax agent, at least for your first return so you have a confirmed baseline to work from in future years: income from more than one country, working holiday visa with a DASP claim on the horizon, ABN or contract income, uncertainty about your residency start date, or you simply want the peace of mind of a professional check in year one.

Either way, the record-keeping habits covered in the deductions article in this series — saving receipts as you go, keeping a simple log of work-related expenses — make the process faster and cheaper regardless of which path you choose, since a tax agent working from organised records charges less time (and often less money) than one reconstructing your year from scratch.

And a final reminder that applies across this whole series: this is general tax information, not advice on your specific return, and it isn't migration advice either. Personal tax questions belong with a registered tax agent you've verified on the TPB register; visa and migration questions belong with a MARA-registered migration agent — Migratio matches you with one for free.

Is it worth paying for a tax agent for a simple first Australian tax return?

Not necessarily — if your situation is one employer, no overseas income, and standard deductions, the free ATO myTax system is genuinely built for exactly that case. An agent becomes worth it once foreign income, ABN work, DASP claims, or residency uncertainty enter the picture.

How much does a registered tax agent cost for an individual return in Australia?

Commonly $100 to $280 at the lower end for a straightforward return, with a broader typical range of $100 to $400 depending on complexity and location, as at 2026. More complex returns (foreign income, contractor income, rental property) cost more. The fee is generally deductible the following year.

How do I check a tax agent is actually registered?

Search the free Tax Practitioners Board public register at tpb.gov.au by their name or registration number before engaging them. Only registered agents can legally charge a fee to prepare or lodge your return.

Can I do my own tax return even in my first year in Australia?

Yes, if your situation is straightforward — being new to the country doesn't itself require an agent. The ATO's myTax system guides you through common situations. Complexity in your specific circumstances, not how long you've been here, is what should drive the decision.

What situations specifically call for a tax agent over DIY?

Foreign income, working holiday DASP claims, ABN or contract income, genuine uncertainty about your tax residency start date, or simply wanting professional confirmation in your first year — all reasonable reasons to use a registered agent rather than lodge yourself.

Is this article telling me what to do with my specific return?

No. It's general guidance on how to decide between DIY and using an agent. Your specific return should be assessed by a registered tax agent if there's any complexity or uncertainty. For visa questions, Migratio matches you with a MARA-registered migration agent free.
