Yes, you can do bookkeeping without a BAS agent in Australia, but know the limits and rules to stay compliant and avoid costly mistakes. It’s important to know the difference between general bookkeeping tasks and the specific work that requires a BAS agent registration.
Bookkeepers manage daily financial records like bank reconciliations, accounts payable and receivable, and payroll data entry using popular cloud accounting software such as Xero, MYOB, or QuickBooks.
However, when it comes to lodging Business Activity Statements (BAS), Instalment Activity Statements (IAS), or handling GST, PAYG, and superannuation reporting, only registered BAS agents who meet strict requirements set by the Tax Practitioners Board (TPB) are legally allowed to perform these tasks.
Understanding these limits will help you stay compliant with Australian Taxation Office (ATO) rules and avoid penalties. This guide explains what bookkeeping tasks you can do without BAS registration, what work requires a BAS agent, the differences between bookkeepers and BAS agents, and important legal qualifications you should be aware of.
What Bookkeeping Tasks Can You Do Without Being a BAS Agent?

As a bookkeeper in Australia, you can perform many everyday bookkeeping tasks without needing to be a registered BAS agent.
These include:
- Managing accounts payable and receivable: Handling invoices and payments to ensure your business keeps track of money owed and incoming funds.
- Performing bank reconciliations: Matching your accounting records with bank statements to ensure everything balances correctly.
- Entering payroll data: Recording employee hours and wages, but not processing payroll payments or reporting to tax authorities.
- Using cloud accounting software: Utilising programs like Xero, MYOB, or QuickBooks to organise and maintain your financial data accurately.
Being aware of the boundaries of your work is important. Although you can undertake these general bookkeeping services with confidence, in order to comply with Australian tax rules, only registered BAS agents are permitted to complete tax reporting responsibilities, such as filing Business Activity Statements (BAS).
Who is registered Tax Agent?
A Registered Tax Agent is a certified expert who is permitted to provide more tax services than merely bookkeeping and BAS filing. Registered Tax Agents, as opposed to BAS agents, can help with income tax return preparation and filing, handling complicated tax issues, offering tax advice, and defending clients in interactions with the Australian Taxation Office (ATO). They can assist both people and corporations with all of their tax-related concerns because they usually have more qualifications and adhere to tougher regulations.
What Tasks Require a Registered BAS Agent?
Certain tasks require registration with the Tax Practitioners Board (TPB) as a BAS agent. These include:
- Lodging Business Activity Statements (BAS)
- Lodging Instalment Activity Statements (IAS)
- Reporting and advising on GST (Goods and Services Tax), PAYG (Pay As You Go) withholding, and superannuation obligations
- Ensuring compliance with ATO (Australian Taxation Office) rules for BAS-related matters
Performing these activities without being a registered BAS agent can lead to serious penalties, including fines and legal action from the ATO and TPB.

Legal Requirements and Qualifications in Australia to be a BAS Agent

To become a BAS agent, you must register with the Tax Practitioners Board (TPB). The main requirements include:
- Holding at least a Certificate IV in Accounting and Bookkeeping or equivalent qualification
- Having relevant work experience in bookkeeping or accounting
- Agreeing to uphold the Code of Professional Conduct set by the TPB
- Completing ongoing professional education to maintain skills and knowledge
These steps ensure registered BAS agents have the qualifications and ethical standards needed to support business compliance. If you’re considering becoming a BAS agent or need a registered agent, contact ISM Accountants in Perth, WA, for expert assistance.
Risks of Doing BAS Work Without Registration
Providing BAS services without being properly registered as a BAS agent comes with serious risks, including:
- Penalties and fines imposed by the Australian Taxation Office (ATO) and the Tax Practitioners Board (TPB), which can be costly and damaging.
- Legal liability not only for the unregistered bookkeeper but also for business owners who hire unregistered individuals to perform BAS work.
- Damage to professional credibility and trust, as clients and authorities expect compliance with the law, and failure to do so can harm your reputation.
Alternatives if You’re Not a BAS Agent
If you are not a registered BAS agent, you can still:
- Work as a general bookkeeper within the allowed scope of tasks
- Collaborate with or outsource BAS lodgement and related tax tasks to a registered BAS agent or tax agent
- Use cloud accounting software to maintain accurate records while ensuring BAS submissions are handled by a registered professional
- Employ a registered BAS agent specifically for BAS and IAS lodgements

Do Business Owners Need a BAS Agent?
Business owners in Australia can lodge their own BAS and IAS without being registered agents, as long as they do it themselves. However, if they want to engage a third party to lodge or manage BAS, that third party must be a registered BAS agent.
While some owners manage their BAS lodgements on their own, it is best practice to hire a qualified BAS agent to avoid compliance issues and penalties.
