Most Australian business owners cannot clearly explain the difference between their bookkeeper, their BAS agent, and their accountant. Many are paying their accountant to do bookkeeping work. Some have a bookkeeper who is lodging BAS without the legal authority to do so. And a surprising number have no idea that a BAS agent is a separate, registered profession with its own legal scope.
The confusion costs money. A $2 million revenue business paying its accountant $25,000 per year might be spending $15,000 of that on bookkeeping tasks that should cost $6,000. Understanding who does what, what each one legally can and cannot do, and what each costs in 2026 is the first step to getting your finance function right without overpaying. Not sure what your business actually needs? Take our free bookkeeper assessment to find out.
A bookkeeper maintains your financial records. They reconcile bank accounts, code transactions to the correct accounts in your chart of accounts, process payroll, manage accounts payable and receivable, and prepare BAS for review. A competent bookkeeper keeps the financial engine running day to day.
What they cannot legally do (unless also a registered BAS agent): lodge BAS or IAS with the ATO, provide advice on GST treatment of transactions, or represent you in dealings with the ATO on BAS-related matters. What they cannot do at all: prepare income tax returns, provide tax advice, advise on entity structures, or represent you to the ATO on income tax matters.
A BAS agent is registered with the Tax Practitioners Board (TPB) under the Tax Agent Services Act 2009. Registration requires supervised experience and passing the TPB exam. A registered BAS agent can prepare and lodge BAS and IAS, advise on GST obligations and treatment, represent you to the ATO on BAS-related matters, and advise on superannuation guarantee obligations.
What they cannot do: prepare income tax returns, provide income tax advice, advise on entity structures or Division 7A, prepare financial statements for tax lodgement purposes, or represent you to the ATO on income tax matters.
A registered tax agent can do everything the bookkeeper and BAS agent can do, plus prepare and lodge income tax returns, provide tax planning and structuring advice, advise on entity structures (company, trust, sole trader), manage Division 7A compliance, handle FBT returns, represent you to the ATO on all tax matters, and prepare financial statements for lodgement. See our guide on how much accountants cost for a full breakdown.
Entry-level bookkeepers (data entry, basic reconciliation): $40 to $50 per hour. Experienced bookkeepers (full reconciliation, payroll, BAS preparation): $50 to $70 per hour. Senior or specialist bookkeepers (complex awards, multi-entity, inventory): $70 to $80 per hour.
On a monthly retainer basis, bookkeeping services range from $300 to $2,500 per month depending on transaction volume and scope. A typical small business with 50 to 100 transactions per month pays $800 to $1,200. A business with 300 or more transactions per month pays $1,500 to $2,500. See our cost of bookkeeping guide for a detailed breakdown by business size and our bookkeeping cost estimator to model your specific situation.
Standard quarterly BAS preparation and lodgement: $150 to $300 per quarter. Complex BAS (multiple GST methods, adjustments, large transaction volumes): $300 to $500 per quarter. Monthly IAS lodgement: $100 to $200 per month.
Many bookkeepers are also registered BAS agents, which means you get both services from one provider. This is generally the most cost-effective arrangement for businesses up to $5 million in revenue.
Graduate or junior accountant: $150 to $200 per hour. Manager level: $200 to $300 per hour. Partner or director: $300 to $500 per hour. Big 4 partner: $500 to $800 per hour.
On an annual compliance basis: sole trader return $500 to $1,500, company return $1,500 to $4,000, trust return $1,500 to $4,500, multi-entity group $5,000 to $20,000 or more. These fees cover the tax return and financial statements only. Advisory, tax planning, and ATO correspondence are typically billed separately.
This is the key insight most business owners miss. The three roles overlap significantly in day-to-day practice, and most SMEs are paying the wrong person for the wrong work.
Worked example: A $2 million revenue business paying its accountant $25,000 per year. When you break down the time allocation, approximately 80 per cent ($20,000) is spent on bookkeeping tasks: reconciliation, transaction coding, BAS preparation, payroll queries. Only 20 per cent ($5,000) is actual accountant work: tax return, financial statements, tax planning. The effective hourly rate for bookkeeping at this firm: approximately $300 per hour. Market rate for that same work from a bookkeeper: $50 to $70 per hour. The annual overpayment: roughly $12,000 to $15,000.
Worked example: A professional services firm paying $35,000 per year to their accountant. Of that, $28,000 is data entry, reconciliation, and BAS preparation. Only $7,000 is tax planning and compliance. An outsourced bookkeeper at $1,500 per month ($18,000 per year) plus the accountant doing only compliance ($7,000 to $10,000) equals $25,000 to $28,000 total. Same outcome, $7,000 to $10,000 cheaper per year. Model this for your own business with our hire vs outsource calculator.
Under $500,000 revenue: a bookkeeper is usually sufficient for the day-to-day work. Engage an accountant annually for the tax return. Total annual cost: $3,000 to $8,000.
$500,000 to $2 million: you need a bookkeeper keeping records weekly, a registered BAS agent lodging BAS (ideally the same person as your bookkeeper), and an accountant annually for the return and basic tax planning. Total annual cost: $8,000 to $18,000.
$2 million to $5 million: bookkeeping becomes more complex (higher transaction volumes, payroll, multi-state operations). You need a more sophisticated bookkeeping arrangement, a registered BAS agent for lodgement, an accountant for compliance and advisory, and potentially some ad hoc financial analysis and reporting. Total annual cost: $18,000 to $40,000.
$5 million and above: this is where the blended team model makes sense. The volume and complexity justify a full finance function covering bookkeeping, BAS, payroll, management reporting, cashflow forecasting, and strategic oversight. Trying to piece this together from separate bookkeeper, BAS agent, and accountant relationships creates coordination overhead, communication gaps, and often higher total cost than an integrated solution. See our finance manager vs bookkeeper vs accountant vs CFO guide for a deeper comparison at each stage.
Understanding the qualification pathway helps you evaluate providers and understand what you are paying for.
Certificate IV in Accounting and Bookkeeping: the baseline qualification for bookkeeping. Covers double-entry accounting, BAS preparation, payroll, and use of accounting software. Does not authorise BAS lodgement.
BAS Agent registration: requires a relevant qualification plus 1,400 hours of supervised experience over a minimum of two years, passing the Tax Practitioners Board exam, ongoing continuing professional education, and professional indemnity insurance. This is the minimum required to lodge BAS on behalf of clients.
CPA (Certified Practising Accountant) or CA (Chartered Accountant): university degree in accounting plus completion of the CPA or CA program (typically 3 to 6 years of study and mentored experience post-degree). CPAs are recognised by CPA Australia. CAs are recognised by Chartered Accountants Australia and New Zealand (CA ANZ). Both are widely respected, and for most SME purposes, the practical difference is minimal.
Registered Tax Agent: requires a CPA, CA, or equivalent qualification, plus a minimum of two years of relevant experience, application to the TPB, and ongoing compliance with the Tax Agent Services Act 2009. Only registered tax agents can prepare and lodge income tax returns.
Accounting and bookkeeping rates vary across Australian cities, generally reflecting the cost of living and local market demand. Sydney commands the highest rates for all three roles, with bookkeepers at $50 to $80 per hour, BAS agents at $100 to $150, and accountants at $200 to $400. Melbourne sits slightly below at $45 to $75 for bookkeepers, $90 to $140 for BAS agents, and $180 to $350 for accountants. Brisbane and Perth are typically 10 to 20 per cent below Sydney rates. Regional and rural areas offer the most competitive pricing, with bookkeepers at $35 to $60 per hour and accountants at $120 to $250.
These differences can be significant over a year. A business paying $250 per hour for a Sydney accountant to do $50 per hour bookkeeping work is losing $200 per hour on that misallocation. See our bookkeeper pricing guide for detailed rate data by city and experience level.
Only if they are also a registered BAS agent with the Tax Practitioners Board. Many experienced bookkeepers hold BAS agent registration, but not all. If your bookkeeper is preparing and lodging your BAS without being registered, you both have a compliance problem. Ask to see their TPB registration number, or look them up on the Tax Practitioners Board register.
In most cases, yes. They serve different functions. Your bookkeeper handles the ongoing operational work: reconciliation, coding, payroll, BAS preparation. Your accountant handles the annual compliance and advisory work: tax return, financial statements, tax planning, entity structuring. Paying your accountant to do bookkeeping is like paying your surgeon to take your blood pressure. Technically they can do it, but it is an expensive use of their time. Our bookkeeping vs accounting guide covers where the line should sit.
Both are fully qualified professional accountants. CPA (Certified Practising Accountant) is the designation from CPA Australia. CA (Chartered Accountant) is the designation from Chartered Accountants Australia and New Zealand. The qualification pathways are slightly different, but both require a degree, a professional program, mentored experience, and ongoing professional development. For SME purposes, either qualification indicates a fully competent professional accountant.
Ask your accountant to break down their annual fee by task type. If more than 50 per cent of the fee is for bookkeeping-related work (reconciliation, transaction coding, BAS preparation, payroll queries), you are almost certainly overpaying. That work should be done by a bookkeeper at $40 to $80 per hour, not an accountant at $150 to $400. Use our employee cost calculator to see what an in-house bookkeeper would actually cost, or our bookkeeping cost estimator for outsourced pricing.
Only on GST and superannuation guarantee matters, which fall within the BAS agent scope under the Tax Agent Services Act 2009. A BAS agent cannot advise on income tax, entity structures, capital gains tax, Division 7A, FBT, or any other area outside the BAS services scope. For those matters, you need a registered tax agent (which is what most people mean when they say "accountant").
At minimum: BAS agent registration (so they can lodge your BAS), proficiency in your accounting software (Xero, MYOB, or QuickBooks), experience with businesses of similar size and complexity to yours, professional indemnity insurance, and references from current clients. Bonus: experience with your specific industry, which matters for correct coding and compliance. See our 2026 bookkeeper pricing guide for what to expect at each experience level.
