Only 16,965 people in Australia are legally allowed to lodge your BAS for a fee, and you can confirm whether yours is one of them in under a minute, for free (TPB Annual Report 2024-25). Most business owners take "I'm a registered BAS agent" on trust. But the title "bookkeeper" is completely unregulated, so that claim is unverifiable without checking the register yourself.
This guide gives you the exact click-path on the TPB public register, explains every status label you might see, covers the entity-mismatch trap that causes the most false negatives, and tells you what to do if your bookkeeper doesn't appear. It's a 60-second check that can save you thousands. For the full picture on hiring, see the complete guide to hiring a bookkeeper in Australia.
TL;DR: Anyone lodging your BAS for a fee must be a TPB-registered BAS agent, one of 16,965 in Australia at 30 June 2025 (TPB Annual Report 2024-25). Verify them free at tpb.gov.au/public-register: search their name or registration number, confirm the status reads "Registered", and check for conditions or sanctions. It takes under 60 seconds and the register updates daily.
How do I check if a bookkeeper is TPB-registered?
The TPB public register is free, requires no login, and updates daily: go to tpb.gov.au/public-register, enter the bookkeeper's legal name or registration number, and confirm the status reads "Registered" (TPB Public Register, 2025). The search accepts three inputs: the practitioner's legal name, the name of their company or trust, or their TPB registration number.
Here's the five-step click-path:
- Go to tpb.gov.au/public-register. No account or login required. The page loads a simple search form.
- Enter the bookkeeper's legal name, their ASIC business name, or their TPB registration number if they've given it to you. You can also filter by practitioner type, state, or suburb to narrow results.
- Hit "Find". Results appear in a table with summary information for each matching entry.
- Click the information icon next to the name to open the full detail panel, which shows registration number, status, expiry date, practitioner type, and any conditions or sanctions.
- Confirm all four things in the detail panel: status reads "Registered", practitioner type is "BAS agent" or "tax agent", the registration hasn't expired, and there are no conditions or sanctions that concern you.
The TPB public register is the definitive source for verifying a bookkeeper's BAS agent status in Australia. It is free to search, requires no login, and is updated daily to reflect current registration status, including conditions, suspensions, and sanctions (TPB Public Register, 2025). Search inputs include legal name, ASIC business name, or registration number.
What should you look for in the search result?
A valid result must show four things: status reads "Registered", a registration number is present, practitioner type is "BAS agent" or "tax agent", and the registration is current, not expired (TPB Help Using the Register, 2025). Missing any one of them is a reason to ask questions before handing over BAS work.
At 30 June 2025 there were 63,865 registered tax practitioners in Australia: 16,965 registered BAS agents and 46,900 registered tax agents (TPB Annual Report 2024-25). Both types can provide BAS services. Only tax agents can also lodge income tax returns. If your provider holds tax agent registration, that covers all BAS work and more.
The results table shows a summary row for each match. The detail panel (click the info icon) shows the full picture: registration number, registration type, status, registration period, conditions, and whether any sanctions are recorded. Don't stop at the summary. Always click through to the detail.
One important distinction: a bookkeeper registered as a tax agent has broader scope than a BAS agent alone. They can do income tax returns in addition to all BAS work. If your provider shows up as a tax agent, their registration fully covers your BAS needs. For more on what each registration type covers, see the difference between a registered BAS agent and a bookkeeper.
What do "conditions", "suspended" and "sanctioned" mean?
A registration can read "Registered" and still carry conditions that limit what services the practitioner can provide, or flags like Suspended, Sanction, or Under ART review that change what they're allowed to do for you. Check the full detail panel, not just the headline status (TPB Help Using the Register, 2025). Sanctions other than a written caution stay on the register for at least five years, with the reasons shown.
Conditions are separate from status. A "Registered" practitioner can still have conditions attached, for example, a restriction on the types of BAS provisions they can advise on. Conditions appear only in the detail panel, not the summary table. Always click through.
What each status label means in plain English:
- Registered: Full registration, active. You're good to proceed.
- Registered – Suspended: Registration is paused. They can't legally do BAS work during the suspension. Don't let them lodge or advise.
- Registered – Sanction: Still registered, but a formal sanction has been imposed. Read the sanction type and reasons before deciding whether to engage.
- Terminated: Registration cancelled. Hard stop.
- Under ART review: Administrative Review Tribunal is reviewing their registration. Wait for the outcome before engaging them for BAS work.
- Renewal application lodged: Normal transition; current registration remains valid while the renewal processes.
What is the registered tax practitioner symbol?
The TPB symbol is a trademark registered practitioners can display alongside their registration number, but the symbol alone proves nothing (TPB – About the registered tax practitioner symbol, 2025). Use it as a prompt to check, not confirmation in itself. Always verify the registration number on the public register.
The Tax Practitioners Board's "Find a BAS agent you can trust" awareness campaign ran through 2025-2026, encouraging small business owners to verify their provider on the public register (TPB – Promoting registered BAS agents, 2025). The TPB explicitly states that the registered tax practitioner symbol does not certify service quality, only registration status, and only as verified by a live register check.
The symbol typically appears in a bookkeeper's website footer, email signature, or engagement letter, often next to a seven-digit registration number. If you see the number, search it. Looking up a registration number directly is the fastest possible check. If you see the symbol without a number, ask for it.
One firm caveat the TPB makes clearly: the symbol does not certify service quality. A registered BAS agent can display the symbol and still do poor work. Registration is the legal floor, not a quality rating. For a full list of questions that do assess quality, see the questions to ask before you hire a bookkeeper.
Why does TPB registration matter? (What you lose without it)
Using an unregistered preparer strips two core protections: you lose safe-harbour relief from ATO penalties when a lodgement is wrong, and they likely carry no professional indemnity insurance to cover their mistakes (TPB – Risks of using unregistered preparers, 2025). The provider faces the civil penalties; you wear the tax debt with no insured recourse.
Under section 50-5 of the Tax Agent Services Act 2009, providing BAS services without TPB registration carries civil penalties of up to $82,500 per breach for individuals and $412,500 for companies, imposed by the Federal Court on application by the TPB (TPB sanctions guidance, 2025). The provider wears those penalties; the client loses the safe-harbour protection that registered agents pass to their clients.
The real client exposure isn't the penalty on the provider, it's the combination of an unpaid tax debt you didn't know about, no recourse against the person who caused it, and no registered agent to deal with the ATO when things go wrong. Safe harbour is the key protection registered agents pass on to clients. Without it, you're fully exposed.

What if your bookkeeper isn't on the register?
Before concluding they're unregistered, check the entity: registration is often held by the company or trust rather than the individual practitioner's personal name, or vice versa (TPB – Help using the register, 2025). This entity-mismatch trap is the most common source of false negatives, and almost no competing guide covers it.
The entity-mismatch trap: A bookkeeper who operates through a company or trust holds the registration in the entity's name, not their personal name. If you search "Jane Smith" and nothing appears, try "Smith Bookkeeping Pty Ltd" or their ABN. Most directory profiles list the entity name; that's the one to search. We see this constantly with sole traders who've recently incorporated, and it's the #1 reason owners wrongly panic about an unregistered bookkeeper.
If you've searched both the individual name and the entity name and still can't find a result, you have four options:
- Ask directly for their registration number. A registered BAS agent knows their number immediately. Hesitation here is a genuine red flag.
- Request supervision details. An unregistered bookkeeper can legally prepare BAS data under the supervision of a registered agent. Ask who the supervising registered agent is and verify that person's registration instead.
- Lodge a complaint with the TPB. If you believe they're providing BAS services without registration, you can report it at tpb.gov.au. The TPB actively investigates; in 2022, 133 of 2,661 TPB allegations involved unregistered practitioners providing tax or BAS services (TPB / Austaxpolicy.com, 2022).
- Switch providers. Search our directory of Australian bookkeepers by suburb and service.
One legitimate scenario worth knowing: an unregistered bookkeeper doing pure data entry and reconciliation under a registered agent's supervision doesn't need their own registration. The registered agent takes responsibility for the BAS work. This is common in bookkeeping firms, and it's legal, as long as someone in the chain is actually registered and supervising the work.
Frequently Asked Questions
Is checking the TPB register free?
Yes. The TPB public register is completely free, requires no login, and is open to anyone. Search by name, ABN, or registration number at tpb.gov.au/public-register. The register is updated daily, so the status you see reflects the bookkeeper's current standing with the TPB (TPB, 2025).
How long does a TPB register check take?
Under 60 seconds with a name or registration number. Go to tpb.gov.au/public-register, type the bookkeeper's legal name or registration number, hit Find, and confirm the status reads Registered. The whole process costs nothing and takes less than a minute (TPB, 2025).
My bookkeeper isn't on the register, is that illegal?
Only if they're providing BAS services for a fee: lodging your BAS, advising on GST or PAYG liabilities, or dealing with the ATO on your behalf. Pure bookkeeping (data entry, reconciliation, payroll runs) needs no registration. If they're doing BAS work for money and aren't registered, that breaches section 50-5 TASA (TPB, 2025). Learn more about what counts as a BAS service and what doesn't.
How often is the TPB register updated?
Daily. From 1 July 2024, BAS agent registration renews annually rather than every three years, so the register reflects current standing far more frequently than before. A search today shows today's status, not last year's (TPB, 2024).
What's the difference between a registration number and the TPB symbol?
The registration number is the unique identifier you can search on the TPB register to verify current status; it's the definitive proof. The TPB symbol is a trademark practitioners can display with their registration number, but it's a marketing asset. The symbol doesn't prove current registration; the number does (TPB – About the symbol, 2025).
Do the 60-second check, every time
Verifying your bookkeeper's TPB registration is one of those five-minute jobs most owners skip and occasionally regret. The register is free, public, and updated daily. There's no reason not to run it before any engagement.
Key takeaways:
- Verify before you sign: run the check before any engagement, not after a problem surfaces.
- Check status + number + type + currency: all four must be present in the full detail panel.
- Read conditions and sanctions: "Registered" isn't always a clean result.
- Check the entity, not just the person: registration may sit with their company or trust.
- Unregistered = no safe harbour, no PI cover: the protection gap is real and expensive.
