What’s the Difference Between a Tax Agent and a BAS Agent?

Not sure whether you need a tax agent or a BAS agent to help with your business finances? Here’s how to pick the right support (and stay compliant).

SHARE TO

If you run a small business, you’ve probably worked with both tax agents and BAS agents. While both help with tax and compliance, their roles can be more different than you might expect.

Here’s how to tell them apart, what each can actually do, and how to work out which one your business needs.

What Is a BAS Agent?

A registered BAS agent is authorised by the Tax Practitioners Board (TPB) to prepare and lodge:

Business Activity Statements (BAS)
Instalment Activity Statements (IAS)
PAYG withholding
Goods and services tax (GST) reporting and claims
Superannuation guarantee obligations

Most BAS agents also handle bookkeeping, payroll, and software support for small businesses without an in-house finance team.

What Is a Tax Agent?

Tax agents cover everything BAS agents do, plus:

Lodge your income tax return (business or personal)
Provide advice on capital gains tax (CGT)
Prepare fringe benefits tax (FBT) returns
Advise on tax planning, structure, and deductions
Handle trust and company tax compliance
Represent you in dealings with the Australian Taxation Office (ATO)

Before a tax agent can offer these services, they must be registered with the TPB.

Tax Agent vs BAS Agent

Do Sole Traders Need a BAS Agent or a Tax Agent?

If you’re a sole trader registered for GST, a BAS agent can handle:

Your quarterly BAS lodgements
Super and payroll
Business-related GST claims

For your individual tax return or advice on deductions and structure, you’ll need a registered tax agent.

If you’re a sole trader registered for GST, a BAS agent can handle:

Your quarterly BAS lodgements
Super and payroll
Business-related GST claims

For your individual tax return or advice on deductions and structure, you’ll need a registered tax agent.

How About Companies and Trusts?

If you run a company or trust, you’ll usually need both:

A BAS agent to manage your bookkeeping, payroll, and BAS lodgements
A tax agent to handle your year-end tax returns and provide tax planning

Having both a BAS agent and a tax agent helps make sure nothing gets missed.

So, Who Should You Work With?

For day-to-day bookkeeping, payroll, GST, and BAS services, stick with a registered BAS agent.

How to Check if Your Agent Is Registered

Check the Tax Practitioners Board (TPB) Register to confirm your agent is qualified. Search by name or business here: https://myprofile.tpb.gov.au/public-register/

The TPB registers and regulates tax practitioners, ensuring they follow the Tax Agent Services Act 2009, including the Code of Professional Conduct.

Manage Expense Categories and Stay Compliant

In short, BAS agents handle GST, BAS, payroll, super, and bookkeeping. Tax agents look after income tax, tax advice, business structure, and ATO issues.

Both matter for compliance, but you can’t swap one for the other.

Not sure where to start? Use a BAS agent for your regular obligations. At Simplify, we’ll keep your books sorted and your BAS accurate, and we’ll work with your tax agent if and when needed.
