What is a BAS agent?

Updated 23 July 2026 5 min read

A BAS agent is a professional registered with the Tax Practitioners Board (TPB) to charge a fee for BAS services — preparing and lodging Business Activity Statements and advising on GST, PAYG withholding and similar obligations. Many bookkeepers are registered BAS agents. Charging for BAS services without registration is not permitted.

This glossary article about bas agent provides general information about Australian employment law and workplace practices. It does not constitute legal, HR, or professional advice and should not be relied on as a substitute for advice specific to your business, workforce, or circumstances.

What a BAS agent does

A registered BAS agent can charge to provide BAS services, including:

  • Preparing and lodging your Business Activity Statement
  • Advising on GST and PAYG withholding obligations
  • Dealing with the ATO on BAS matters on your behalf
  • Running payroll and calculating PAYG and superannuation as part of BAS services

A BAS agent is often a bookkeeper who has met the TPB's registration requirements.

Registration requirements

Under the Tax Agent Services Act 2009, charging a fee for BAS services requires registration as a BAS agent with the Tax Practitioners Board (TPB). Registration requires set qualifications (typically a Certificate IV in Accounting and Bookkeeping plus a board-approved course), relevant experience, insurance and adherence to a Code of Professional Conduct. Verify registration on the TPB public register.

BAS agent vs tax agent

Both are TPB-registered, but a BAS agent's authorisation is narrower. A BAS agent handles BAS, GST and PAYG; a tax agent can additionally prepare income tax returns and give tax advice. If you need your tax return done, you need a tax agent, not just a BAS agent.

Key takeaways

A BAS agent is TPB-registered to charge for BAS services — BAS lodgement, GST and PAYG. Many bookkeepers hold this registration. It's narrower than a tax agent's, which also covers income tax returns. For accountants and bookkeepers, BAS agent registration is the gateway to charging for payroll and BAS work — see adding payroll to your services.
