BAS agent vs tax agent: who can do what?

A BAS agent helps with matters such as GST and PAYG withholding. A tax agent has a broader registration that also covers income tax services. Either may be useful to a small business, but their job titles alone won't tell you which tasks are included in a quote.

Start with your unfinished work. Is it a quarterly activity statement, a company tax return, or six months of transactions nobody has reconciled? Those are different jobs, even when one practice offers to do all three.

Compare the work, then the registration

The Tax Practitioners Board explains the scope of BAS services and tax agent services. The latter includes BAS services. Both registrations can carry conditions, and an agent should only take on work they can competently perform.

Work you need	Registration to look for when engaging paid tax help
Advice on GST treatment and preparing a BAS	BAS agent or tax agent
PAYG withholding advice associated with payroll	BAS agent or tax agent
Preparing your business's income tax return	Tax agent
Income tax advice about how to pay yourself	Tax agent
Recording transactions using instructions already supplied	Depends on the actual work; routine data entry isn't automatically a BAS service
A cash flow discussion	Ask what advice is involved; a spreadsheet review and tax advice are different services

This table describes registration scope, not a promise that every registered practitioner offers every service. A tax agent who mainly prepares individual returns may not be the right person to maintain a shop's inventory records.

For the broader definition, see what a BAS agent does. If you're ready to compare providers, use our BAS agent hiring guide.

Why a bookkeeper's work can cross the boundary

Consider two requests you might send to someone who helps with your accounts:

1. Enter these invoices using the coding instructions our registered agent supplied.
2. Decide which of these invoices include GST we can claim, then calculate our BAS figures.

The second request involves applying tax rules you intend to rely on. Calling the service bookkeeping doesn't remove the registration question.

The TPB's registration guidance explains the requirement for paid tax and BAS services and the exemptions. Staff working on behalf of a registered practice may not need individual registration where they aren't providing services in their own right. Don't assume the same answer applies to every independent contractor.

Ask the practice to name the entity responsible for your engagement. If a staff member prepares the work, ask who reviews it and whose registration covers the service.

Three workable ways to organise the jobs

One practice handles the accounts and tax

This can suit an owner who wants one place to send questions. Ask whether the monthly fee includes bookkeeping, payroll, BAS preparation and the annual return. Also ask whether different people handle these jobs internally and how information moves between them.

The main practical risk is assuming a service is included because the practice offers it. An annual tax engagement might leave you responsible for every quarterly activity statement.

A BAS agent and tax agent share the work

You might use a BAS agent for regular records and activity statements, with a tax agent handling income tax and structure questions. Agree on the handover before the first quarter ends.

For example, ask the BAS agent to maintain a list of transactions awaiting the tax agent's advice. Ask the tax agent to explain any year-end journals so the next BAS isn't prepared from records someone has changed without telling the other person.

You keep the records and engage help for review

This can work when you have time to keep records consistently and know when a transaction needs advice. Ask the reviewer what a usable file looks like. They may want reconciled accounts, supporting documents and an unresolved-items list before accepting it.

Our MYOB bookkeeping checklist gives you a practical monthly routine. The same questions about evidence and reconciliation matter whichever software you use.

Write down who owns each deadline

Here is a starting worksheet for a business using two advisers. Fill it in with names and dates before relying on it.

Task	Person preparing it	Person reviewing or approving it	Evidence of completion
Monthly records	Agreed preparer	Agreed reviewer	Reconciliation reports and open questions
BAS	Named agent or owner	Business's authorised approver	Lodgement receipt and payment instructions
Payroll reporting	Named payroll operator	Agreed reviewer	Submission status and exception notes
Annual income tax return	Named tax agent	Business's authorised approver	Signed declaration and lodgement receipt

Keep payment responsibility separate from lodgement responsibility. Someone submitting a form doesn't necessarily arrange payment from your bank account. Confirm the applicable BAS due date for your circumstances rather than assuming an agent extension applies.

When a question needs another professional

An accountant might identify a tax issue in a contract without being the person who should draft that contract. A BAS agent might notice a payroll discrepancy without being qualified to advise on a disputed employment classification.

Ask your adviser what they can resolve, what needs referral, and what documents the next professional will need. A useful handover states the question clearly enough that you don't pay someone else to reconstruct it.

Key takeaways

• Match registration and experience to the actual task.
• Tax agent registration includes BAS services, but a quote may not include BAS work.
• One practice or several can work if responsibility and handovers are clear.
• Keep a record of approvals, lodgements and payments as separate steps.
