Bookkeeper, BAS Agent or Accountant: Who Does What in Australia, and What Each Can Legally Do

Last updated: 27 September 2026. Written by the FreeMyCloud team.

In Australia the bookkeeper vs accountant question is settled by law, not by job title. A bookkeeper records and reconciles what happened in the business. A registered BAS agent can also prepare, confirm and lodge activity statements, run payroll that involves interpreting tax law, and deal with the ATO on GST, PAYG and superannuation guarantee matters. A registered tax agent, which is what most accountants who do tax work are, can prepare and lodge income tax returns and advise on any taxation law. The dividing line is the Tax Agent Services Act 2009: anyone who provides a BAS service or a tax agent service for a fee must be registered with the Tax Practitioners Board (TPB), unless a narrow exemption applies. The word “accountant” is not what the law regulates. The service is.

This article is for Australian business owners and office managers deciding who should keep the books, who should lodge the BAS, and who should do the tax return. It does not cover financial advice licensing or company audit.

What can a bookkeeper legally do without being registered?

Quite a lot, provided the work does not involve interpreting or applying a tax law for a client who will rely on it. The TPB’s BAS services page lists services that are not BAS services and need no registration: data entry that does not require interpreting a tax law; coding tax invoices under the instruction and supervision of a registered tax or BAS agent; installing accounting software without setting the client’s default GST codes; transmitting Single Touch Payroll data where the transmission itself involves no interpretation; general software training; and non-tax advice on salary packaging.

So in the bookkeeper vs accountant split, an unregistered bookkeeper can reconcile bank accounts, chase debtors, pay creditors, process pay runs from rates the employer or the employer’s agent has set, and produce management reports. The work becomes agent work the moment the bookkeeper decides which GST code applies, confirms the figures on the activity statement, or tells the ATO anything on the client’s behalf.

What is a BAS agent, and what can a registered BAS agent do?

A BAS agent is a person, company or partnership registered with the TPB to provide BAS services for a fee. Under section 90-10 of the Tax Agent Services Act, a BAS service means working out or advising about a client’s liabilities, obligations or entitlements under a BAS provision, or representing the client to the Commissioner of Taxation on one, where the client can reasonably be expected to rely on that work. The BAS provisions are the GST law, wine equalisation tax, luxury car tax, fuel tax credits, the PAYG withholding and instalment system, and the collection parts of fringe benefits tax.

Since 2020 the TPB has also declared further services to be BAS services, so a registered BAS agent’s lawful scope, per the TPB list, includes: preparing, confirming and lodging activity statements; payroll that involves interpreting a tax law, including setting up Single Touch Payroll; superannuation guarantee shortfalls, charge statements and clearing house payments; the Taxable payments annual report (TPAR); tax file number declarations and ABN applications; GST, PAYG withholding and FBT registrations; and acting as the client’s authorised ATO contact on activity statement and superannuation guarantee debts.

What a BAS agent cannot do for a fee is anything outside those provisions: an income tax return, an FBT return, or advice on deductions, capital gains, Division 7A or trust distributions. Those are tax agent services.

What does an accountant do, and is “accountant” a regulated title?

“Accountant” describes a profession, not a licence. Management accountants, auditors and tax accountants are all accountants, and the Tax Agent Services Act says nothing about the word. It regulates tax agent services: working out or advising about a client’s position under any taxation law, or representing the client to the Commissioner, where the client will rely on it. Section 50-5 makes it unlawful to charge a fee for such a service without being a registered tax agent. So the accountant who prepares your tax return, lodges your FBT return or negotiates an income tax debt with the ATO is, or works under, a registered tax agent.

Membership of CPA Australia, Chartered Accountants ANZ or the Institute of Public Accountants is a separate credential, not a TPB registration. A CPA who has never registered as a tax agent can prepare management accounts for a fee but cannot lodge your tax return. The useful fact in the bookkeeper vs accountant comparison is that a registered tax agent can do everything a registered BAS agent can, because the TPB treats BAS services as a subset of tax agent services.

Bookkeeper vs accountant vs BAS agent: who can do which job?

“Bookkeeper” in the table means a bookkeeper not registered with the TPB. Each “Yes” in the registered columns comes from the TPB’s published service lists; the bookkeeper column comes from the “not a BAS service” examples on the same page.

Task	Bookkeeper (unregistered)	Registered BAS agent	Registered tax agent
Bank reconciliation, debtors, creditors, data entry	Yes	Yes	Yes
Deciding which GST code applies to a transaction	Only under a registered agent’s supervision	Yes	Yes
Processing a pay run from rates already set	Yes	Yes	Yes
Working out PAYG withholding, setting up STP, tax on leave or termination payments	No	Yes	Yes
Preparing, confirming or lodging a BAS or IAS	No	Yes	Yes
Superannuation guarantee charge statement, TPAR, TFN declarations, ABN application	No	Yes	Yes
Dealing with the ATO on GST, PAYG or SGC debts and payment plans	No	Yes	Yes
Preparing and lodging an income tax return or FBT return	No	No	Yes
Division 7A, capital gains, trust distribution advice, objections	No	No	Yes
Client gets ATO safe harbour and agent lodgement due dates	No	Yes, on activity statements	Yes

The pay run row causes the most confusion. Pressing “process” on a pay run whose rates and withholding settings were set by the employer or a registered agent is not a BAS service. Setting up those rules is.

How do you become a registered BAS agent or tax agent?

The requirements sit in the Tax Agent Services Regulations 2022, and the two bars differ, which is the practical reason a tax agent usually charges more than a BAS agent, who in turn charges more than a bookkeeper.

Requirement	BAS agent (individual)	Tax agent (individual, main pathway)
Primary qualification	At least a Certificate IV in bookkeeping or accounting	A degree or postgraduate award in accounting (other pathways: a diploma, a law degree, or 8 years of experience)
Board-approved courses	Basic GST/BAS taxation principles, including the Act and the Code	Australian taxation law and commercial law
Relevant experience	1,400 hours in the past 4 years, or 1,000 hours for a voting member of a recognised association	12 months full-time equivalent in the past 5 years with an accounting degree; 2 years with a diploma; 8 years in the past 10 without one
Other conditions	At least 18, fit and proper, professional indemnity insurance that meets TPB requirements	Same
Application fee (indexed each 1 July, no GST)	$58 as listed by the TPB at 1 July 2026	$290 as listed by the TPB at 1 July 2026
Once registered	Bound by the Code of Professional Conduct, continuing professional education, renewal after at least one year	Same

Sources: TPB pages on BAS agent qualifications, tax agent qualifications, BAS agent registration and tax agent registration. The Code of Professional Conduct is the part that matters most to a client: the agent must act honestly, keep client information confidential, take reasonable care in working out the client’s affairs and applying the law, hold professional indemnity insurance, and account for client money held on trust.

What happens if an unregistered person prepares your BAS or tax return?

Two things, landing on different people. The preparer faces civil penalties under the Tax Agent Services Act. The business remains fully liable for whatever was lodged, without the protection a registered agent would have brought.

For the preparer, the Federal Court can impose a civil penalty of up to 250 penalty units for an individual and 1,250 for a body corporate for charging a fee for a BAS or tax agent service while unregistered, and up to 50 and 250 penalty units for advertising such services or claiming to be registered (TPB civil penalty provisions). The ATO’s penalty unit table sets one unit at $364 for infringements on or after 1 July 2026, which puts the maximum at $91,000 for an individual and $455,000 for a company.

The register is public. Anyone can search the TPB Register by name, business name or registration number. Checking takes a minute and is worth doing before handing over a file.

Why does registration matter to the business, not just the agent?

Safe harbour. Under the ATO’s safe harbour provisions, a business is not liable for a failure-to-lodge penalty, or a false or misleading statement penalty that produced a shortfall, if it gave its registered agent all the relevant information in time and the problem arose from the agent’s lack of reasonable care. The burden of proof sits with the taxpayer and it does not cover recklessness, but it exists only when a registered agent lodged.

Later due dates. The ATO’s registered agent lodgement program gives agents extra time on most quarterly activity statements, except the December quarter, which already includes a one-month extension, per the ATO’s due dates page. The 2026-27 dates are in our BAS due dates guide.

Accountability. A registered agent who fails to take reasonable care can be investigated by the TPB, sanctioned and struck off, and those outcomes appear on the public register.

Which does a growing Australian business actually need?

Most businesses need all three functions. The bookkeeper vs accountant decision is really about who performs each one and how the hand-offs work.

• An individual operator with no staff and simple GST. Bookkeeping is a few hours a month. Many owners keep the ledger themselves or use a bookkeeper for reconciliation, and have their registered tax agent review and lodge the BAS with the annual return.
• The first employee. Payroll brings PAYG withholding, Single Touch Payroll and superannuation guarantee into play, and setting those up is a BAS service. The business now needs a registered BAS agent, an accountant’s practice that covers payroll setup, or an employee who does it in-house.
• Quarterly BAS with real volume. Once there are hundreds of transactions a month, the reliable model is a bookkeeper who keeps the file reconciled every week and a registered agent who reviews and lodges each quarter. The review takes an hour instead of a day because the ledger is already clean.
• Multiple entities, a trust, directors’ loans, property. Income tax work becomes the bigger cost and a registered tax agent does most of the thinking. The bookkeeper’s job is to make year-end fast.
• Contractors in building, cleaning, courier, IT or security services. Add TPAR to the agent’s lodgements. Our TPAR guide covers who lodges and the 28 August deadline.

The common thread: bookkeeping and lodging are different jobs, usually best done by different people. The bookkeeper is in the file every day. The agent carries the registration, the insurance and the responsibility for what goes to the ATO.

Where does an outsourced bookkeeper fit in?

In the bookkeeper’s seat, not the agent’s. FreeMyCloud is not a registered tax or BAS agent and does not lodge on a client’s behalf. Since 2010 the firm has placed university-qualified graduate accountants, based in the Philippines, with Australian businesses as their dedicated bookkeeper. That person works inside the client’s own Xero, MYOB, QuickBooks or Reckon file during Australian business hours, keeps reconciliations current, processes pay runs, and prepares the quarterly BAS workpapers so the client’s registered BAS or tax agent reviews and lodges from a file that is already ATO-ready.

The registered agent keeps the legal responsibility, the safe harbour and the ATO relationship. The bookkeeping, which is most of the hours, is done by a dedicated person at typically 50 to 70% less than a local equivalent. The bookkeeping services for small business page sets out the weekly scope, and the savings calculator shows the cost against a local hire.

Frequently asked questions

Can a bookkeeper lodge a BAS in Australia?

Only if the bookkeeper is a registered BAS agent or tax agent, or is an employee lodging their own employer’s BAS. Preparing, confirming or lodging an activity statement for a fee is a BAS service under the Tax Agent Services Act 2009, and doing it unregistered carries a civil penalty of up to 250 penalty units ($91,000 at the $364 unit value from 1 July 2026). An unregistered bookkeeper can reconcile the file and prepare workpapers for a registered agent to review and lodge.

What is the difference between a BAS agent and a tax agent?

Scope. A registered BAS agent can work on the BAS provisions only: GST, PAYG withholding and instalments, fuel tax credits, wine and luxury car tax, plus the payroll, superannuation guarantee, TPAR and ABN services the TPB has declared to be BAS services. A registered tax agent can advise on and lodge under any taxation law, including income tax returns, FBT returns and objections. Every tax agent can provide BAS services; a BAS agent cannot provide tax agent services.

Do I need a BAS agent if I already have an accountant?

Not necessarily. If your accountant is a registered tax agent, they are already permitted to prepare and lodge your activity statements and handle payroll and superannuation guarantee matters. Many businesses split the work anyway, using a bookkeeper or BAS agent for the quarterly cycle and the tax agent for the annual return, because it is usually cheaper. Which arrangement suits your business is a question for your registered agent.

How do I check whether someone is a registered BAS agent or tax agent?

Search the TPB Register at tpb.gov.au/public-register by name, business name or registration number. The register shows the registration type, any conditions on it, and any sanctions on the public record. Registered practitioners can also display the Registered tax practitioner symbol. If a person says they are registered but does not appear on the register, the TPB accepts complaints about unregistered preparers.

Can our in-house bookkeeper prepare and lodge our BAS without being registered?

Yes, if they are an employee doing it for their own employer. The civil penalty provisions do not apply to an employee who provides a BAS or tax agent service to their employer for a salary or wage. The exemption does not extend to a contractor, a freelancer or a bookkeeping business, even one that has worked with you for years. It also does not give the business safe harbour, which is available only when a registered agent lodges.

Does a bookkeeper need to be registered to run payroll and Single Touch Payroll?

It depends on what part of payroll they do. Processing a pay run using rates and withholding settings already set up by the employer or a registered agent, and transmitting the STP file, is not a BAS service. Setting up STP, working out PAYG withholding, calculating the tax on leave or termination payments, or preparing a superannuation guarantee charge statement are BAS services and require registration unless the employee exemption applies.
