Hiring a bookkeeper without asking the right questions is how one Melbourne café owner ended up with $5,000 in ATO fines and catch-up fees - all because their bookkeeper had been lodging a BAS they weren't legally registered to touch (Supervision Group, 2025). It's not unusual. Eighty-three per cent of ATO failure-to-lodge penalties fall on small business clients (ATO, 2025), and a surprising number trace back to bookkeepers who took on work they weren't qualified for.
Most business owners choose a bookkeeper the way they choose a cleaner - whoever's cheapest and available. They don't know which tasks legally require TPB registration, what insurance to check, or how to spot a pricing structure that's about to blow out. These 12 questions fix that. Use them before you sign anything.
TL;DR: Before hiring a bookkeeper in Australia, confirm three non-negotiables: TPB registration (required by law to lodge BAS for a fee), professional indemnity insurance (minimum $250,000 per claim - ICB/TPB, 2025), and a written engagement letter with a defined scope. Qualified, registered bookkeepers charge $50–$120/hr (ScaleSuite, 2026). The 12 questions below cover everything else.
Questions 1–3: Is This Bookkeeper Legally Qualified?
No formal licence is required to call yourself a bookkeeper in Australia - the title is completely unregulated. The law kicks in the moment someone wants to lodge your BAS, PAYG statements, or super guarantee for a fee. That requires Tax Practitioners Board (TPB) registration. Get these three questions answered before anything else.
Question 1: Are you a registered BAS agent with the Tax Practitioners Board?
Only a TPB-registered BAS agent can legally lodge your BAS, PAYG reports, or super guarantee statements for a fee - providing these services without registration breaches section 50-5 of the Tax Agent Services Act 2009 and carries civil penalties of up to $82,500 per breach for the unregistered provider (Tax Practitioners Board, 2025). Don't take their word for it. Verify in 60 seconds at tpb.gov.au/public-register - the register shows current status, any conditions, and any sanctions, updated daily.
In Australia, only a Tax Practitioners Board-registered BAS agent can legally lodge a BAS, advise on GST or PAYG, or deal with the ATO on a client's behalf for a fee. Providing these services without registration breaches section 50-5 of the Tax Agent Services Act 2009 and carries civil penalties of up to $82,500 per breach (Tax Practitioners Board, 2025). Verify any candidate at tpb.gov.au/public-register before signing an engagement letter.
If they're unregistered, you also lose the safe-harbour protection that registered agents extend to their clients - meaning you carry more exposure in an ATO audit. From 1 July 2024, BAS agent registration renews annually rather than every three years, so the public register reflects current status every day.
This is the most important question on the list. The other eleven are calibrations. This one is binary.
Question 2: What formal qualifications and professional memberships do you hold?
TPB registration to become a BAS agent requires a Certificate IV in Accounting and Bookkeeping (FNS40222), a Board-approved GST/BAS course, and 1,400 hours of relevant experience in the past four years (TPB qualifications, 2025). That's the legal minimum. Above that, look for membership of the Institute of Certified Bookkeepers (ICB) or the Australian Bookkeepers Association (ABA) - both set ongoing CPE requirements and a code of conduct that goes beyond the TPB minimum.
Software certifications matter too. Xero Advisor, MYOB Partner, and QuickBooks ProAdvisor credentials show real competence in the platforms you'll use day-to-day. Ask specifically whether they're certified in the software you already run. If they're a Xero shop and you're on MYOB, a mid-year migration adds cost and risk.
Key Insight
Most hiring guides say "check their qualifications." What they skip: a Certificate IV covers GST basics - it doesn't cover Fair Work award complexity in hospitality, subcontractor withholding in construction, or Medicare billing in allied health. Ask specifically whether they've handled your industry's payroll and GST quirks before. A confident, specific answer is worth far more than a certificate.
Question 3: Do you carry professional indemnity insurance?
All TPB-registered BAS agents must carry professional indemnity (PI) insurance - at minimum $250,000 per claim and $500,000 aggregate for agents earning under $75,000 in annual fee income (ICB/TPB, 2025). PI insurance protects you if a coding error triggers an ATO audit, a missed super payment generates penalties, or a filing mistake creates interest charges you shouldn't owe.
Ask for the insurer name and policy number. A legitimate, registered provider shares this in seconds. Hesitation or vagueness is a red flag.

Questions 4–5: Does This Bookkeeper Know My Industry?
Qualifications get a candidate in the room. Industry experience determines whether they're right for your business. Every sector in Australia carries its own payroll, GST, and compliance nuances - a bookkeeper who's never worked in your industry will spend your first six months learning on your dime.
Question 4: Have you worked with businesses in my industry before?
There are over 95,000 bookkeepers employed across Australia (Jobs and Skills Australia, 2025), and their practical experience varies enormously by sector. Hospitality involves Fair Work award complexity and split-shift penalty rates. Construction involves the Taxable Payments Reporting System for contractors. Allied health involves Medicare and NDIS billing nuances. E-commerce involves GST on cross-border digital goods. Each of these creates specific coding requirements in Xero or MYOB that a generalist bookkeeper can easily get wrong.
Ask them for a concrete example: "Give me a compliance issue specific to my industry that you've had to resolve." Vagueness is a tell. If they can't name a real scenario, they probably haven't seen one.
Question 5: How long have you been in practice - and can you share two references from businesses similar to mine?
Tenure matters because experience compounds. A bookkeeper who has been through three or four EOFY cycles understands the pressure points - BAS deadline clashes with payroll runs, ATO system outages in June, last-minute reconciliation errors before the accountant handover - that newer practitioners haven't encountered.
Request two references from businesses comparable in size and industry. Don't just collect the names - follow them up. A 10-minute call with a past client tells you more than any CV. Ask them: "Did they catch anything before you knew it was a problem?"
Questions 6–7: How Is My Data Handled?
Your financial records contain payroll details, supplier relationships, revenue figures, and banking information. How a bookkeeper stores and accesses that data matters for security - and for your obligations under the Privacy Act 1988.
Question 6: What accounting software do you work with, and what level of certification do you hold?
The three main platforms in Australia are Xero, MYOB, and QuickBooks Online. Xero dominates the small-business segment, and Xero Partner status - Bronze, Silver, Gold, Platinum - reflects the volume and verified quality of a bookkeeper's Xero work. A Platinum Xero Partner is processing a large, accurate book of Xero clients. A first-time Xero user is not.
This question has a practical edge. If you switch software because your new bookkeeper doesn't support what you already run, the migration costs hours of reconciliation, re-keying of data, and exposure to errors during the transition. Always ask: "Are you certified in the software I'm currently using?"
Question 7: Is any of my data processed or stored outside Australia - and if so, where?
Many Australian bookkeeping firms outsource data processing to teams in the Philippines, India, or elsewhere. This is legal, and plenty of providers do it compliantly - with written data-handling agreements and explicit client consent. Many do not disclose it at all.
Under the Privacy Act 1988, businesses must take reasonable steps to protect personal information and, where it's disclosed overseas, must take reasonable steps to ensure the overseas recipient handles it appropriately (OAIC, 2025).
Ask directly: "Is any of my financial data processed outside Australia? If yes - which country, which provider, and what data-handling agreement governs it?" A provider who can't answer clearly doesn't have a data governance process. That's a risk to you.
Key Insight
No competitor article on "questions to ask a bookkeeper" addresses the Privacy Act angle on offshore data processing. It's a genuine exposure most AU business owners have never considered. If your provider sends your payroll data to a processing team overseas without disclosure or consent, you have no visibility into who accesses it or what happens if it's breached. This question costs nothing to ask.
Questions 8–10: What Are You Actually Charging For?
At $50–$120/hr, a bookkeeper who's vague about scope or billing is expensive to discover mid-engagement. These three questions pin down what you're getting, what you're paying, and how the relationship ends at year-end.
Question 8: What exactly is included in your fee - and what triggers additional charges?
A written scope of work should list every service explicitly: data entry, bank reconciliation, accounts payable and receivable, payroll processing, STP lodgement, BAS preparation, BAS lodgement (BAS agents only), super guarantee calculations, monthly P&L reports, and ATO correspondence handling. The ATO requires businesses to retain financial records for a minimum of five years (ATO record keeping, 2025) - ask whether the bookkeeper will help you maintain that obligation or simply hand you files.
The extras that trigger surprise invoices most often: audit support, unexpected ATO correspondence, year-end handover prep for your accountant, and software migration. Get these on the engagement letter before you start.
Question 9: What pricing model do you use - hourly, fixed monthly, or package?
Qualified, registered bookkeepers in Australia charge $50–$120/hr (ScaleSuite, 2026). Hourly billing suits variable workloads but creates exposure when scope isn't tightly managed. Fixed monthly retainers offer predictability - but only if the scope is documented and revision clauses are spelled out. Package pricing bundles a defined set of services at a flat rate and works well for straightforward small businesses with consistent transaction volumes.
Qualified, registered bookkeepers in Australia charge $50–$120 per hour in 2026. Rates below $40/hr typically indicate an unregistered operator, an offshore provider, or a business not covering its own compliance costs - which means corners will eventually be cut on yours. Fixed monthly retainers for a small business with standard needs typically run $300–$800 per month (ScaleSuite, 2026).

Question 10: How do you coordinate with my accountant - and what does the year-end handoff look like?
The bookkeeper–accountant handoff is where most financial errors surface. A clean year-end means a reconciled trial balance, all accounts verified, super confirmed as paid, and files exported in a format the accountant can open without rework. Ask what format they export - Xero reports, MYOB data file, trial balance in Excel - and whether they've worked with your accountant before.
If your bookkeeper and accountant have never interacted, schedule a short introduction early. The cost of a misaligned year-end handoff is always higher than the cost of a 30-minute call in January.
Questions 11–12: What Happens When Things Go Wrong?
No bookkeeper is perfect. What separates a professional provider from a risk is not whether they make mistakes - it's how they handle them when they do.
Question 11: What is your process if you make an error that affects my tax obligations?
A professional answer has three parts: they carry PI insurance to cover the cost of correction, they will fix the error at their own expense, and - if the error created an ATO compliance issue - they will correspond with the ATO on your behalf under their registered agent status. That third part is only possible if they're a registered BAS agent.
A concerning answer: deflection ("it rarely happens"), blame-shifting ("that would be your accountant's problem"), or an inability to name their PI insurer. If they told you in Question 3 that they carry PI insurance, the insurer's name should take them five seconds to recall.
Question 12: Who will actually handle my books day-to-day - and how fast do you respond to urgent queries?
Many bookkeeping firms operate as teams, not sole practitioners. That's often fine - team coverage means continuity when your assigned bookkeeper is unavailable. It does raise a question, though: are all team members who will handle your BAS work TPB-registered? Ask how they document internal hand-offs so context doesn't get lost between team members.
On response time: the ATO frequently sends correspondence with 14 or 28-day reply windows. Ask whether they commit to responding to urgent queries within one business day. Then get that commitment in the engagement letter.
Key Insight
When we reviewed 15 AU bookkeeping firm websites and hiring guides to compile this checklist, the same questions appeared on every list: qualifications, software, pricing. The questions almost none of them included: offshore data processing (Question 7), the written scope of work for extras (Question 8), and the bookkeeper-to-accountant handoff process (Question 10). Those three gaps are where the expensive surprises tend to live.
Watch for these red flags before signing anything:
- Offering to lodge your BAS for a fee without showing TPB registration
- Can't name their PI insurer or provide a policy number on request
- Quoting below $35/hr - typically signals an unregistered operator, offshore white-labelling, or a provider not covering their own compliance costs
- A verbal scope of work with no written engagement letter
- Unable to name a reference from a business similar to yours
- Offshore data processing disclosed only when you ask, with no written data-handling agreement
Two or more of these in a first conversation is a clear signal to keep looking. The cost of a bad bookkeeping hire isn't just the hourly rate - it's the catch-up fees, ATO penalties, and accountant overtime to fix the records that follow.
These 12 questions cover five areas: legal qualification, industry fit, data security, pricing clarity, and error accountability. Question 1 - TPB registration - is the one non-negotiable. Everything else helps you find the right fit; that one keeps you out of legal trouble.
Once you've worked through the list, request a written engagement letter that documents the answers to Questions 8, 9, and 12 at minimum. A bookkeeper who resists a written scope is telling you something important about how they'll handle your finances.
