How Much Does a Tax Return Cost in Australia 2026

Last updated: September 2026

How much does a tax return cost in Australia? Lodging it yourself through myTax is free. A registered tax agent charges roughly $100–$300 for a straightforward salary-and-wage return, $150–$800 for a sole trader, and $1,300–$3,600 for a company once financial statements are included. The spread is enormous because "a tax return" covers everything from a one-page PAYG summary to a trust distribution minute.

Tax time is the one bill most Australians pay without ever asking what it's for. You hand over your payment summaries, you get a number back, and somewhere in the middle a fee appears that you can't really interrogate — because you have no idea what the job involved.

This guide fixes that. It breaks down what tax agent fees actually buy, how the price changes between an individual, a sole trader, a company and a trust, what pushes a quote up, and whether the fee is deductible. Prices are AUD and we've flagged GST throughout, because accounting fees carry it and plenty of published "from $X" pricing quietly doesn't include it.

Key takeaways

• Lodging your own return through myTax costs nothing, and the ATO's Tax Help volunteers will do it free for people earning $70,000 or less.
• A registered tax agent typically charges $100–$300 for a simple individual return; high-street chains advertise from about $109 for a basic return with deductions under $300.
• Sole trader tax return cost runs $150–$300 at the budget end and $300–$800 through a full-service accounting firm in Sydney or Melbourne.
• Across the accounting firms that price work through Leadkit's fee calculator, the base annual tax return fee sits at $990 ex GST, scaled down for individuals and sole traders and up for companies and trusts.
• Yes, a tax agent fee is tax deductible — you claim it at D10, cost of managing tax affairs, in the year you incur it. A fee paid in October 2026 lands on your 2026–27 return, not this one.
• Engage an agent before 31 October 2026 and most individuals move from the 31 October deadline to 15 May 2027 under the agent lodgement program. Leave it later and you've already missed the window.
• The $1,000 instant work-related deduction does not apply to the return you're lodging now — it starts in the 2026–27 income year and covers employment income only.

How much does a tax return cost in Australia?

A tax return costs $0 if you lodge it yourself, $100–$300 for a simple individual return through a registered tax agent, and $400–$2,100 ex GST for a business return depending on your entity type and how messy the year was.

The table below is the annual tax return line item from the rate card inside Leadkit's accounting services fee calculator — the tool accounting firms embed on their own websites to quote this work. It starts from a base annual return fee of $990 ex GST and applies two multipliers: your entity type, and how complex your industry is.

All figures are ex GST — add 10% for the invoice total. A $990 return is $1,089 including GST.

Disclaimer: This is a price indication only. Your accountant or tax agent will confirm the final price after reviewing your situation. Figures are general estimates as at September 2026 and will vary by firm, city and the state of your records.

Methodology and Leadkit's relationship to this data: these figures come from the default rate card inside Leadkit's own accounting services fee calculator, cross-checked against published Australian tax agent pricing current as at September 2026. Leadkit builds and operates that calculator, so this is first-party data from a tool we own — not independent third-party research. We've said so plainly rather than dressing it up as a survey.

One thing worth naming: this card reflects full-service accounting practices — the kind that also do your bookkeeping, BAS and financial statements. A high-street tax agent doing a single walk-in return sits well below it. If you want the broader picture across bookkeeping, BAS and advisory work, our Australian accounting fees guide covers the whole engagement rather than just the return.

What are tax agent fees actually paying for?

Tax agent fees pay for three things: data collection, judgement calls, and the professional indemnity that sits behind the signature. The typing is the cheap part.

Data collection is the grind. Your agent pulls prefill from the ATO, chases the income streams prefill misses — a share sale, a rental statement, a crypto disposal, a foreign pension — and reconciles it against what you've handed over. On a simple return this takes twenty minutes. On a messy one it takes three phone calls and a fortnight.

Judgement is where the fee earns itself. Is that laptop a full deduction or a depreciating asset? Does the home office qualify under the fixed rate or actual cost method? Is the rental repair a repair or a capital improvement? Each of those is a defensible position an agent has to be willing to stand behind if the ATO asks.

Then there's the registration itself. Only a registered tax agent can charge a fee to prepare and lodge your return, and registration means checked qualifications, professional indemnity insurance and a code of conduct enforced by the Tax Practitioners Board. Search the TPB register before you pay anyone — it takes thirty seconds and the number should be on their invoice.

A term worth knowing: a BAS agent is not the same as a tax agent. A BAS agent can prepare and lodge your activity statements and handle payroll and GST obligations, but cannot prepare your income tax return. Plenty of small businesses use a BAS agent through the year and a tax agent once a year, and that split is usually cheaper than putting everything with one firm.

How much does a sole trader tax return cost?

A sole trader tax return costs $150–$300 through a budget or online tax agent, and $555–$970 ex GST through a full-service accounting firm — because a sole trader return isn't one return, it's an individual return with a business schedule bolted on.

That business schedule is the whole story. Your agent has to produce a profit and loss for the ABN, apply the right depreciation treatment to tools and vehicles, sort personal use out of every shared expense, and check whether the personal services income rules catch you. A courier with one van and a spreadsheet is a $300 job. A contractor with three income streams, a ute on finance and eighteen months of unreconciled bank feeds is not.

The single biggest lever on your own fee is the state of your records. Agents price the mess, not the revenue. A sole trader who hands over a reconciled set of accounts pays the simple-affairs rate; one who hands over a shoebox pays for the bookkeeping first and the return second — and bookkeeping on that same rate card starts at $300 a month ex GST before any complexity loading.

If you're registered for GST, the quarterly activity statement is a separate line again: $165 per quarter ex GST at the base rate, or about $660 a year. Worth modelling your GST position before you commit — the GST calculator will tell you what you're actually holding on behalf of the ATO.

Want to know what you'll get back before you pay anyone? Run the numbers through the free income tax calculator first — it takes about a minute, and knowing the refund makes the fee much easier to judge. Results are an indication only.

What does a company, trust or partnership return cost?

A company tax return costs $1,030–$1,800 ex GST on its own, but almost no company gets away with just the return — add financial statements and the realistic annual compliance bill is $2,500–$3,800 ex GST.

Here's why. A Pty Ltd company has to prepare financial statements — a balance sheet, a profit and loss, and the notes that reconcile them — before anyone can prepare the return. On the same Leadkit rate card, financial statements carry a base fee of $1,500 ex GST, scaled by the same entity and complexity multipliers. A moderate-complexity company therefore runs roughly $1,285 for the return plus $1,950 for the statements: about $3,235 ex GST, or $3,560 including GST, for the annual compliance package.

Trusts cost more again because of the distribution minute. A family trust has to resolve how income is distributed to beneficiaries before 30 June, and the return then has to match that resolution across every beneficiary's individual return. Getting it wrong is expensive in a way a late lodgement never is.

Partnerships sit in the middle — one partnership return plus an individual return for each partner, which is why two-partner structures often surprise people with the total.

And if you run a self-managed super fund, that's a separate engagement entirely: $2,500 a year ex GST for SMSF administration on the base card, before the mandatory independent audit, which is a different firm and a different invoice.

These are the base rates before entity type, industry complexity and transaction volume multipliers are applied. This is a price indication only — your accountant will confirm the final price after reviewing your situation.

Capital gains are the other line that blows a business return out. If you've sold property, shares or a business asset during the year, model the position before your appointment with the capital gains tax calculator — walking in with a cost base already assembled saves real money.

What pushes an accountant tax return cost up?

Six things move an accountant tax return cost, and only one of them is your income. In rough order of impact:

• Entity type. Moving from an individual to a company roughly doubles the fee; a trust more than doubles it. The structure is the price, not the profit.
• Industry complexity. Multiple revenue streams, intercompany transactions or specialist reporting — mining, agriculture, property development — carry a loading of up to 1.8x on the same base fee.
• Transaction volume. Under 500 transactions a month is one price band; over 5,000 a month carries an 1.8x loading on bookkeeping and BAS work.
• Number of entities. A company plus a trust plus two individuals is four returns, not one engagement with a discount.
• Record quality. Reconciled accounts versus a folder of photographed receipts is the difference between the low and high end of every band above.
• Timing. Walking in during the last week of October costs more at plenty of firms than walking in during August, and it removes your agent's ability to negotiate a deferral if something goes wrong.

Two of those — record quality and timing — are entirely within your control, and between them they're worth several hundred dollars on a typical small business engagement.

A note on how fees get presented. Across the 90 quote-style calculators in Leadkit's library, 89 display a price range rather than a single number, with an average variance of about ±15% — and the accounting fee calculator uses ±12%. That's not vendors hedging. It reflects a real truth about professional services pricing: until someone has seen your records, the honest answer is a band, not a figure. Treat any accountant who quotes a precise number sight-unseen with mild suspicion.

Can you do it free? myTax and Tax Help

Yes. myTax is free, available 24 hours a day through myGov, and for a straightforward salary-and-wage return with prefilled data it takes about twenty minutes. Most refunds land within two weeks.

myTax is genuinely good for a specific profile: one or two employers, bank interest, private health cover, and work deductions you can substantiate. The ATO prefills your income, your health insurance and often your bank interest, so a large share of the return is already done when you open it.

It stops being the right tool the moment you have a rental property, a capital gain, a business schedule, foreign income, or a deduction you're not certain about. That's not a technology limit — it's that myTax will happily let you lodge a wrong position, and the penalty for an incorrect claim lands on you, not on the software.

The ATO also runs the Tax Help program, where trained volunteers help eligible people lodge online for free. Eligibility is broadly an income of $70,000 or less with simple affairs, and it runs from July through October at community centres and libraries around the country. Details are on the ATO's help and support page. ASIC's Moneysmart lodging a tax return guide is the other free resource worth ten minutes before you decide.

The honest test: if a tax agent will find you more than their fee in deductions you'd have missed, they're free. If your return is two payment summaries and a union fee, they're an expense.

Is a tax agent fee tax deductible?

Yes — a tax agent fee is tax deductible, and you claim it at question D10, "cost of managing tax affairs", on your individual return. The ATO's D10 guidance for the 2026 return sets out exactly what's in scope.

The timing catches people out. The fee is deductible in the year you incur it, not the year the return relates to. So the fee you pay in October 2026 to lodge your 2025–26 return is a deduction on your 2026–27 return, lodged the following year. Colloquially people say "you claim it next year" — that's what they mean.

What's in scope at D10 is broader than just the preparation fee:

• Preparing and lodging your tax return and activity statements
• Tax advice from a recognised tax adviser — and only from a recognised adviser; advice from an unregistered person isn't claimable
• Tax return software, apportioned if you also use it for other purposes
• Travel to get tax advice
• Litigation costs, including court and Administrative Review Tribunal fees

What's not deductible: the cost of preparing a return for anyone else, general financial advice that isn't tax advice, and ATO interest and penalties themselves.

On the $1,000 instant deduction everyone's asking about. The $1,000 standard work-related expense deduction was legislated in 2026 but applies from the 2026–27 income year, lodged from 1 July 2027 — not to the return you're lodging now. It also covers employment income only, so sole trader and business deductions continue under the normal substantiation rules regardless. Treasury's consultation material on the instant deduction sets out the mechanics if you want the detail.

What are the 2026 deadlines — and what does being late cost?

If you lodge your own 2025–26 return, it's due 31 October 2026 — and because that falls on a Saturday, you have until Monday 2 November 2026. If you engage a registered tax agent before 31 October, most individuals move to 15 May 2027 under the agent lodgement program.

The lodgement program is a concession the ATO extends to registered agents so the work doesn't all land in one week. Three conditions matter:

1. You must be on the agent's client list before 31 October. Engaging an agent on 5 November doesn't backdate anything — you're already late.
2. Your prior years must be lodged. Any outstanding return removes the concession and pulls you back to 31 October.
3. A large prior-year liability can bring your date forward. Agents will tell you if that applies to you.

There's also a further concession to 5 June 2027 for most individuals, provided any tax owing is paid by that date.

Miss it and the failure-to-lodge penalty applies at one penalty unit for each 28 days (or part) the return is overdue, up to a maximum of five units — the current value of a penalty unit is published by the ATO and rises periodically. Worse than the penalty is the interest, which accrues on unpaid tax from the due date regardless of when you lodge.

The practical advice: if you know you'll owe money, lodge on time and arrange a payment plan. Lodgement and payment are separate obligations, and the ATO treats a late lodgement far more harshly than a late payment you've talked to them about.

How to compare tax agent quotes without getting burnt

Get two written quotes, insist both are quoted on the same scope, and check whether the number includes GST. Most fee disputes are scope disputes wearing a price costume.

Ask these five questions of anyone quoting you:

• What's in the fee and what's extra? Amended returns, rental schedules, capital gains calculations and ATO correspondence are commonly charged separately.
• Is that ex or inc GST? Accounting fees attract GST. Across Leadkit's 90 quote calculators, 66 display GST as a separate line rather than folding it into a headline — if a quote doesn't break it out, ask.
• What's your TPB registration number? Verify it on the register yourself.
• What happens if the ATO queries the return? Some firms include a set amount of correspondence; some bill hourly from the first phone call.
• Do you offer fee from refund? "Fee from refund" means the agent takes their fee out of your refund before passing it on, so you pay nothing upfront. It's convenient, but many providers charge an extra administration fee for the service — it is not free simply because you didn't hand over a card.

A word on monthly retainers, which are now common for small business compliance. Bundling the return, BAS, bookkeeping and a quarterly catch-up into one monthly figure — typically $300–$1,200 a month in the Australian market, depending on size — smooths cash flow and usually costs less than buying the same services piecemeal. Ask for both the bundled and unbundled price so you can see what you're actually paying for the return.

Operator note from our side of the fence: of the 202 calculators in Leadkit's library, 112 are enquiry-only — form-based tools that collect the job details and let the professional quote manually, with no price shown. Accounting is one of the fields where firms most often choose that route, because they genuinely can't price a return until they've seen the records. If an accountant asks you questions before quoting, that's the job being done properly, not stalling.

Frequently asked questions

Q: How much does a tax return cost for a simple individual in Australia?

A: $0 if you lodge it yourself through myTax, and roughly $100–$300 through a registered tax agent for a straightforward salary-and-wage return. High-street chains advertise basic returns from about $109 where total work deductions are under $300, stepping up to around $174 once you claim more than that. A full-service accounting practice typically starts near $400–$495 ex GST for the same job, because the engagement includes a review and a conversation rather than a data-entry appointment. Work out your expected refund on the income tax calculator guide before you choose — if the refund is small and the return is simple, myTax is the rational answer.

Q: Is a tax agent fee tax deductible?

A: Yes. You claim it at D10, "cost of managing tax affairs", and it covers preparing and lodging your return and activity statements, plus tax advice from a recognised tax adviser. The catch is timing: the deduction falls in the year you incur the fee, so a fee paid in October 2026 goes on your 2026–27 return, not the one you're lodging now. Keep the invoice — the ATO expects substantiation for this like any other deduction, and it's one of the most commonly claimed items on the individual return.

Q: How much does a sole trader tax return cost?

A: $150–$300 through a budget or online tax agent, and $555–$970 ex GST through a full-service firm, depending on how complex your industry is and how clean your records are. The fee is higher than a plain individual return because your agent has to prepare a business schedule — profit and loss, depreciation, private-use apportionment — before the return itself. In Sydney and Melbourne the upper end stretches to about $800 at established practices. The cheapest thing you can do to reduce your own fee is reconcile your accounts before the appointment.

Q: Is it cheaper to do my own tax return?

A: In direct cost, always — myTax is free. Whether it's cheaper overall depends on what you'd miss. If your return is one employer and a few standard deductions, doing it yourself is the right call and the agent adds little. If you have a rental property, a capital gain, a business, or you genuinely aren't sure whether something is claimable, an agent who finds one deduction you'd have missed has usually paid for themselves — and the fee is deductible next year on top of that.

Q: What is the deadline for lodging a tax return in 2026?

A: 31 October 2026 if you lodge it yourself, which becomes Monday 2 November 2026 because 31 October is a Saturday. If you're on a registered tax agent's client list before 31 October, most individuals move to 15 May 2027, with a further concession to 5 June 2027 if any tax owing is paid by then. The extension is not automatic — it requires you to be registered with the agent before the October date and to have no outstanding prior-year returns.

Q: Why is a company tax return so much more expensive than an individual one?

A: Because a company return is the last step of a longer job. Financial statements — balance sheet, profit and loss and the notes reconciling them — have to exist before the return can be prepared, and they carry their own fee. On the rate card behind Leadkit's accounting fee calculator, the statements base fee is $1,500 ex GST against $990 for the return itself. Add ASIC annual review obligations and director loan account tracking, and the realistic annual bill for a small Pty Ltd sits around $2,500–$3,800 ex GST.

Q: Does the $1,000 instant deduction mean I don't need an accountant?

A: Not for the return you're lodging now. The $1,000 standard work-related deduction applies from the 2026–27 income year, lodged from 1 July 2027, and it only covers employment income — so it does nothing for sole trader or business deductions. Even from 2027–28 onwards it's a floor, not a cap: if your genuine substantiated work expenses exceed $1,000, you still itemise. It will simplify tax time for employees with modest expenses, and change very little for anyone with a business, a rental or an investment portfolio.

Q: Can I claim the cost of my accountant's advice on setting up a company?

A: Generally not as a D10 deduction — structuring advice is usually capital in nature, and the treatment differs from ordinary tax compliance advice. Some business establishment costs are deductible over time under specific provisions, and a company may be able to claim certain start-up expenses immediately. This is exactly the kind of judgement call worth paying for properly, and it's also why the advisory line on most firms' rate cards — around $200 a month ex GST — is billed separately from the compliance work.

Methodology and data sources

Fee figures in this guide come from the default rate card inside Leadkit's own accounting services fee calculator — the tool Australian accounting firms embed on their websites to quote this work — and from the library-wide statistics of how our 202 calculators present pricing. Leadkit builds and operates those calculators, so this is first-party data from a product we own rather than independent third-party research. Market comparison ranges (the $100–$300 individual band, the $109 chain pricing, the $300–$1,200 monthly retainer band) are drawn from published Australian tax agent pricing current as at September 2026 and are market observation, not our data.

All calculator-derived figures are quoted ex GST unless stated; add 10% for the invoice total. Ranges are general estimates for Australian capital cities and major regional centres — remote areas, specialist industries and multi-entity groups can fall well outside them. This is a price indication only; your accountant or tax agent will confirm the final price after reviewing your situation.
