Every Australian business owner asks the same question at EOFY: is my accountant charging too much? The answer depends on your entity type, the complexity of your affairs, and, more than anything else, the state of your books when they reach your accountant's desk. A clean Xero file with weekly reconciliation might cost $750 to prepare a sole trader return. The same business with nine months of un-reconciled transactions could easily cost $2,200 or more, because your accountant is doing bookkeeping work at $180 per hour before they even start the return.
This guide breaks down what business tax returns actually cost in Australia in 2026, what drives the price up, and how to reduce your EOFY bill without cutting corners on quality.
When your accountant quotes for a "tax return," they are typically quoting for a package that includes several distinct deliverables. Understanding what is in that package helps you evaluate whether the price is reasonable.
For most businesses, the annual compliance package includes: financial statements (profit and loss, balance sheet, and in some cases a cash flow statement), income tax return preparation and lodgement with the ATO, STP finalisation and reconciliation, and a basic review of the prior year's tax position. For companies, add ASIC annual review and compliance. For trusts, add trustee resolutions and distribution minutes. If you have director loans, add Division 7A compliance review. If you have sold assets during the year, capital gains calculations.
Each of these components adds time and cost. A simple sole trader with no employees and a clean set of books is a fundamentally different job from a family group with a trading company, a discretionary trust, and a property holding entity. See our chart of accounts guide for how a well-structured chart of accounts makes the accountant's job faster and cheaper.
A sole trader return is the simplest business return the ATO processes. It includes the business schedule attached to your personal return, plus any applicable deductions for motor vehicle, home office, depreciation, and superannuation.
Worked example (clean books): Sarah runs a graphic design business in Brisbane earning $180,000. Her bookkeeper maintains clean Xero records and lodges BAS quarterly. Her tax return costs $750 including the business schedule, motor vehicle claim calculations, and home office deductions. Total time for the accountant: approximately 3 hours.
Worked example (messy books): James runs a plumbing business in Sydney earning $320,000. He has not reconciled Xero since March. His accountant quotes $2,200: $750 for the return itself and $1,450 for 8 hours of cleanup at $180 per hour. The same return, more than double the cost, because the bookkeeping was not maintained.
A company return requires full financial statements (not just a business schedule), the company tax return, ASIC annual review ($310 in 2026), and potentially Division 7A analysis if the director has a loan account.
Worked example (clean): A Sydney-based IT consultancy turning over $2.5 million with 8 employees. Clean Xero file, monthly BAS lodged on time, payroll finalised via STP. Annual financial statements and company tax return: $2,800. The accountant can move quickly because the data is reliable and current.
Worked example (messy): Same business, but books have not been reconciled since December, three BAS quarters are estimated, and the director loan account has not been tracked. The quote comes back at $6,500, more than double. The accountant needs to reconstruct 6 months of data before they can even begin the return.
Trust returns are more complex because of distribution decisions. The accountant needs to prepare distribution minutes, advise on streaming of capital gains and franked dividends, and consider the tax position of each beneficiary. A discretionary trust distributing to four family members requires four separate calculations to optimise the overall family tax position.
Worked example: A discretionary trust in Melbourne operating a consulting business at $600,000 profit, distributing to the primary beneficiary (the operator), their spouse, and two adult children. The accountant prepares trust financial statements ($1,800), the trust tax return ($600), distribution minutes with streaming advice ($500), and reviews the beneficiaries' individual returns ($400). Total: $3,300.
Partnership returns require a partnership income tax return plus a schedule for each partner showing their share of income and deductions. Complexity increases with the number of partners and any changes in profit-sharing ratios during the year.
Worked example: A family business in Melbourne operates through a trading company ($1.8 million revenue), a family trust holding shares in the company, and a property trust holding the business premises. Package pricing from their accountant: $12,500 covering all three returns, financial statements, distribution minutes, and inter-entity loan reconciliation. This includes approximately 50 hours of work across two staff members and a reviewing partner.
The single biggest variable in your tax return cost is the state of your books. A clean, weekly-reconciled Xero file means your accountant can start the return immediately. A messy file means they spend hours (at $150 to $400 per hour) doing bookkeeping work before the tax work even begins.
Other cost drivers include overdue lodgements (each year behind roughly doubles the work), complexity factors such as international income, R&D tax incentive claims, Division 7A director loan accounts, employee share schemes, or cryptocurrency holdings. Late engagement is another factor: accountants who receive files in September or October (peak season) often apply surcharges of 10 to 20 per cent. Location also matters, with Sydney and Melbourne accountants charging 15 to 25 per cent more than regional practices.

The headline tax return fee is rarely the total annual cost. Here is what else you are likely paying for.
BAS preparation and lodgement (if not bundled separately): $150 to $500 per quarter, or $600 to $2,000 per year. Tax planning advice, often charged as a separate engagement: $500 to $2,000. ATO correspondence and amendment requests if issues arise: $200 to $500 per item. Bookkeeping cleanup before EOFY if your books are not current: $1,000 to $5,000. Payroll finalisation for STP: $200 to $500. ASIC annual review fee for companies: $310 in 2026.
Worked example of the real annual cost: A company with a $2,800 tax return fee, $1,500 in quarterly BAS preparation, $1,200 for a tax planning session, $310 for ASIC, and $500 for STP finalisation. Total annual compliance cost: $6,310. The "tax return" is less than half of it.
For a broader picture of what accountants actually cost, our guide covers everything from hourly rates to annual packages.
A $500 tax return that misses $15,000 in legitimate deductions costs you $4,500 in unnecessary tax at the 25 per cent company rate (or up to $7,050 at the 47 per cent individual marginal rate). Common deductions that cheap or time-poor accountants miss include the instant asset write-off, prepaid expenses brought forward, superannuation contribution timing opportunities, motor vehicle claims using the logbook method, and home office deductions for directors.
The ATO processes roughly 11 million individual tax returns per year. Their own data shows that amendment requests and audit activity increase significantly for returns prepared by the cheapest providers. A few hundred dollars saved on the fee can easily result in thousands lost in missed deductions or, worse, penalties from errors that trigger ATO scrutiny.
Businesses with weekly reconciled books typically pay 30 to 50 per cent less at EOFY than businesses with messy or outdated records. The reason is straightforward: the accountant spends their time on strategy and planning (which saves you money) rather than data entry and cleanup (which costs you money but adds no value).
When your books are clean and current, the tax return process takes weeks instead of months. Your accountant has reliable data to model scenarios: should you make additional super contributions before 30 June? Is it worth bringing forward an equipment purchase? Would restructuring the director's remuneration mix save tax? These questions can only be answered with accurate, up-to-date numbers.
This is exactly what an embedded finance team delivers: clean books year-round so your accountant can focus on the work that actually saves you money.

Accountant hourly rates vary meaningfully across Australian capital cities. Sydney senior accountants typically charge $200 to $400 per hour. Melbourne: $180 to $350. Brisbane: $150 to $300. Perth: $160 to $320. Regional practices generally charge $120 to $250 per hour. These differences flow through to the overall cost of a return, with the same scope of work costing 15 to 25 per cent more in Sydney than in a regional town.
A straightforward company tax return with clean books, a single entity, and no unusual complexity costs $1,500 to $2,500 in 2026. This includes financial statements, the company income tax return, and ASIC compliance. Add $500 to $1,500 for each layer of complexity: director loan accounts requiring Division 7A review, multiple shareholders, international transactions, or R&D claims.
Yes. Tax return preparation fees are tax deductible in the year they are paid. This includes the cost of your accountant preparing and lodging your return, any tax planning advice, and fees for managing ATO correspondence related to your tax affairs. Keep the invoice as your record.
Because they are doing bookkeeping work at accountant rates. When your Xero file has un-reconciled transactions, miscoded entries, or months of missing data, the accountant (or their staff) must clean it up before they can prepare the return. At $150 to $300 per hour, 10 hours of cleanup adds $1,500 to $3,000 to your bill. A bookkeeper does the same work at $50 to $80 per hour. The maths is clear: keep your books clean year-round and save the difference.
Generally, no. Accountants charge $150 to $400 per hour. Bookkeepers charge $40 to $80 per hour. If your accountant is reconciling bank feeds and coding transactions, you are paying three to five times the market rate for that work. The most cost-effective setup is a dedicated bookkeeper or outsourced finance team handling the operational work, with your accountant focused exclusively on tax compliance and advisory. See our accountant vs bookkeeper comparison for more detail on where the line should sit.
Three things will reduce your bill more than anything else. First, keep your books reconciled weekly, not monthly or quarterly. Second, lodge BAS on time every quarter so there are no arrears to sort out at year-end. Third, engage your accountant before 30 June, not after, so they can provide proactive tax planning advice while there is still time to act on it. The combination of clean books plus early engagement typically reduces the total annual compliance cost by 30 to 50 per cent.
The ATO applies a failure-to-lodge penalty of $313 per 28-day period (as at 2026), up to a maximum of $1,565 for small entities. Interest charges (the General Interest Charge) also apply to any unpaid tax from the due date. More importantly, late lodgement puts you on the ATO's radar for compliance activity, which creates additional costs in time and professional fees.
You can lodge your own tax return, but for business returns, using a registered tax agent is almost always worth it. Tax agents get extended lodgement deadlines (up to May of the following year), they are trained to identify deductions you would miss, and they provide a layer of professional protection if the ATO queries anything. For a company, trust, or partnership return, the complexity makes self-lodgement risky. Understand what a BAS agent can and cannot do compared with a registered tax agent.
