BAS agent for small business: how to choose one

Choose a BAS agent for your small business by matching their registration, experience and service scope to the work you need. Check who will do the work, what it will cost and how you'll know the BAS has been lodged. Those details matter more than a package name.

If you're comparing a bookkeeper, BAS agent and accountant, start by listing the jobs you want to hand over. Entering invoices, deciding GST treatment, running payroll and preparing an income tax return aren't interchangeable tasks.

Use the BAS-agent directory to search names and suburbs, filter by state and open the official registration record for contact details. The listings use the Tax Practitioners Board's public dataset. Check the current record before engaging someone; a directory entry doesn't tell you their availability or service quality.

Is there a government list of BAS agents?

Yes. The Tax Practitioners Board (TPB) maintains the public register of tax and BAS agents. You can search a name or registration number, or use its nearby search. The register includes some unregistered and suspended practitioners as well as current registrations, so read the status and full details.

Our directory makes a shortlist easier to browse. Each listing links back to the TPB for the current record and published contact details. It includes the source date and pauses listings if the snapshot becomes too old. We haven't ranked providers or accepted payment for their position.

For the next step, use the enquiry checklist and email template. It helps an agent understand the work before quoting, whether you need quarterly help, regular bookkeeping or a file cleanup.

Work out what you need help with

Write a short brief before requesting quotes. Include your business structure, software, approximate transaction volume, number of employees and how current your records are. Mention unusual transactions or overdue work rather than asking providers to price an apparently tidy file.

Your situation	Service to ask about
Records are up to date but GST questions remain	Review of the specific transactions and BAS preparation
Bank feeds contain months of unmatched items	Initial cleanup, reconciliation and an ongoing routine
You employ staff	Payroll scope, review, reporting and exception handling
BAS is handled but the annual return isn't	A separate tax agent engagement
You want to keep doing the entries yourself	A defined review and escalation arrangement

If you're still sorting out the roles, read BAS agent vs tax agent. You may need one provider or a combination, depending on the work and their capabilities.

Check the responsible entity

The TPB's registration guidance explains the requirement for paid BAS services and the exemptions. Routine data entry isn't automatically tax advice, but deciding GST treatment can cross that boundary. An employee working on behalf of a registered practice may not need a separate individual registration.

Ask for the registration details of the entity accepting your engagement. Then check the TPB record yourself, including status and conditions. A software badge or professional association logo doesn't replace this check.

If you deal with a company, ask who supervises the file. You should know where technical questions go even if a different staff member handles everyday entries.

Compare scope before comparing price

Give every shortlisted provider the same brief. Ask them to separate:

Initial review or cleanup of existing records.
Regular bookkeeping and reconciliation.
BAS preparation, your approval and lodgement.
Payroll work, if needed.
Reports and scheduled review of unresolved items.
Work charged separately, including historical corrections or additional advice.

There isn't a reliable universal price for this mixture of work. A monthly package can be good value or poor value depending on what it includes and the condition of your records. An hourly quote also needs an estimate of time and a rule for approving extra work.

Ask whether the amount includes GST and who pays for the accounting software. If a provider includes the software in its fee, clarify how the subscription and data move if you leave.

The BAS-agent fees comparison shows how two differently structured quotes add up over a year. Its fictional example separates the monthly fee, quarterly BAS charge and one-off cleanup so you can repeat the calculation with your own quotes.

Test how the provider handles a problem

A useful question is: what happens when you find a transaction you can't confidently code?

Look for a clear process for asking you for documents, referring technical questions and recording the final treatment. A promise to make every question disappear may conceal work being guessed or deferred.

You can also ask for an example of the monthly output you'll receive. A report full of totals isn't especially helpful if nobody tells you which records are incomplete. Expect the provider to distinguish finished work from items still awaiting evidence.

For the records you can prepare yourself, use our MYOB month-end checklist.

Agree on deadlines and approvals

Build a simple timetable around the BAS period. Specify when you provide records, when questions come back, when you approve the statement and how you receive confirmation of lodgement.

Check the actual deadline that applies to you. Agent lodgement arrangements depend on eligibility and circumstances; don't assume appointing an agent immediately extends an overdue obligation. Keep payment responsibility clear too. A lodged BAS can still have an unpaid amount.

Our BAS due date guide explains the calendar. Ask your agent to confirm the date and payment arrangements for your business in writing.

Give access deliberately

Agree which records and software permissions are necessary. Use supported user invitations and appropriate access levels, with separate accounts for people doing the work. Keep control of the business's recovery details.

Don't send your personal banking password or myID credentials as a shortcut. If the provider needs you to authorise access, ask for the official process and complete your part through the relevant service.

Discuss where documents are stored, who else can access them and how you retrieve them. These questions remain useful whether the team works locally, remotely or across several locations.

Plan the first month and the eventual handover

Before starting, write down the opening state of the file: last reconciled date, last lodged BAS, outstanding notices and unresolved transactions. This makes it easier to distinguish earlier problems from new work.

If you're changing providers, arrange a specific cutover date. Confirm which person handles the current period and whether any adjustments are pending. Avoid having two people make conflicting changes to the same records.

Use the checklist for switching BAS agents to record the last reconciliation, lodged periods, outstanding questions and access changes in one place.

The engagement should also explain notice, outstanding fees, export formats, access removal and the handover of work in progress. You shouldn't discover these terms only when you decide to leave.

Review whether the arrangement works

After the first agreed cycle, check the basics. Did the file reach the expected state? Were questions clear? Did you receive the promised reports and lodgement evidence? Were extra charges approved first?

A useful provider leaves you better informed about the business, even when they do most of the administrative work. If you still can't tell what's complete, ask for a clearer status report before adding more services.

Key takeaways

Describe your actual records and workload before asking for quotes.
Check the registration of the entity accepting responsibility.
Compare cleanup, recurring work and extras separately.
Agree on access, deadlines, approval, payment and handover.
