How this usually works
The fastest way to answer when to hire a small business accountant is to work backwards from the trigger:
- What changed? (GST registration, payroll starting, software migration, growth or funding)
- What deadline or risk sits behind it? (ATO lodgement, penalties, ASIC, payroll fines)
- What outcome do you need? (clean up, lodge, automate, report, plan)
That turns a vague search into a brief you can send to the right provider. If you know your trigger, you can act now.
Australian context to keep in view
- Registrations drive your obligations: ABN, GST, PAYG withholding, STP payroll, and state payroll tax if applicable.
- Compliance roles are regulated:
- Tax advice/lodgement must be done by a registered tax agent.
- BAS/GST advice/lodgement must be done by a registered BAS agent or tax agent.
- Fit matters: CA/CPA/IPA qualifications, relevant industry experience, scope clarity, and communication rhythm during peak periods (BAS/EOFY).
Signs it’s time to hire a small business accountant
- You crossed the $75k GST threshold or voluntarily registered and now have quarterly BAS.
- You hired staff or contractors and must run payroll with STP, super and PAYG withholding.
- EOFY is approaching and you need tax planning, asset write-offs, or director loan/trust distribution guidance.
- You received an ATO notice, data-matching query, late-lodgement penalty, or audit request.
- Your books are behind, bank feeds aren’t reconciling, or your P&L and BAS don’t align.
- You are changing structure (sole trader to company/trust) or need help with ASIC obligations.
- You are switching or setting up software (Xero, MYOB, QuickBooks) and want a clean implementation.
- Growth decisions require cash flow forecasting, budgeting, or scenario planning.
Who to hire and when
Bookkeeper
Best for day-to-day coding, reconciliations, bills, receipts, and getting your file clean and current. Pairs well with accountants for tax.
BAS agent
Best for GST/BAS, PAYG and payroll-related lodgements. Must be TPB-registered to advise/lodge. Ideal when BAS is the immediate pressure.
Tax accountant
Best for income tax returns, tax planning, structures, ATO reviews and complex issues. Must be a registered tax agent to advise/lodge.
Small business accountant
Best when you want an end-to-end view: bookkeeping oversight, BAS, payroll, tax, reporting and advice aligned to your growth stage.
By business stage: when to hire
- Starting out: get structure, registrations, and software right from day one. A setup hour saves months of cleanup later. New business accountant
- Hiring and scaling: bring in payroll and BAS support first, then add tax planning and reporting cadence. Payroll services
- Established: move to monthly/quarterly close, cash flow forecasts, and proactive tax planning before EOFY.
What to compare before you commit
Scope
Confirm the scope covers setup, cleanup, payroll, BAS, tax, ASIC, reporting and advisory as needed. Ask what’s included, excluded and how out-of-scope work is priced.
Software fit
Check Xero/MYOB/QuickBooks competence, add-ons (Hubdoc/Dext, Receipt Bank, project/job costing), and how they document workflows.
Turnaround and communication
Ask about SLA for emails and lodgements, who your day-to-day contact is, and how they handle urgent ATO deadlines during BAS/EOFY peaks.
Commercial fit
Compare fixed-fee vs hourly, billing cadence, included meetings, and whether you need compliance-only support or broader advisory.
Costs and engagement models
Pricing reflects complexity, volume and turnaround. Common models in Australia include:
- Fixed-fee packages for monthly/quarterly compliance (bookkeeping close, BAS, payroll, management reports).
- Hourly or project fees for catch-ups, file cleanups, or software migrations.
- Retainers for advisory, cash flow forecasting, board packs or regular strategy sessions.
Always request an itemised proposal with deliverables, frequency, deadlines and escalation paths.
Best next steps
Write down the exact outcome you want first. For example, that might be cleaner books, a lodged BAS, reliable payroll, better reporting, a software migration or a more strategic finance view.
Then shortlist providers against that outcome rather than titles alone. The right fit can explain the process clearly, set expectations early and connect the work to the wider needs of the business.
