Filing a firm tax return in Australia is a crucial responsibility for business owners. Whether you run a small enterprise or a large corporation, staying compliant with the Australian Taxation Office (ATO) rules ensures your business operates smoothly and avoids penalties. This guide walks you through the complete process of filing a Firm Tax Return in Australia, explains key tax obligations, highlights the role of accurate record-keeping, and breaks down essential steps to make your tax filing efficient and stress-free.
Understanding Firm Tax Return in Australia
What is a Firm Tax Return?
A firm tax return is a formal declaration of a business’s income, expenses, deductions, and tax liabilities submitted to the ATO. It determines how much income tax your firm owes based on its taxable income.
Who Needs to File?
Every registered business entity in Australia, including sole traders, partnerships, companies, and trusts, must lodge an annual tax return. Firms that operate as companies are subject to different rates and rules compared to sole traders.
Filing Deadlines
- Small businesses generally need to file by 31 October if lodging themselves.
- With a registered tax agent, the deadline may extend to May the following year.
Failing to file on time can result in penalties and interest.
Key Australian Firm Tax Rules to Know
1. Company Tax Rate
As of the 2024–25 financial year:
- Base rate entities (firms with aggregated turnover less than $50 million and 80% or less of passive income): 25%
- Other companies: 30%
2. Taxable Income
Your taxable income includes all assessable income minus deductions. Common deductions include business operating expenses, depreciation, and salaries.
3. GST Registration
If your firm earns over $75,000 annually, GST registration is mandatory. You must report and remit GST to the ATO regularly, often quarterly.
4. PAYG Instalments
Firms may need to make Pay-As-You-Go (PAYG) instalments throughout the year to pre-pay tax obligations.
5. Record-Keeping
Under Australian firm tax rules, businesses must retain financial records for at least five years. This includes:
- Invoices
- Receipts
- Bank statements
- BAS (Business Activity Statements)
Step-by-Step Guide to Filing a Firm Tax Return in Australia
Step 1: Organise Financial Records
Ensure all income, expenses, and other financial records are up-to-date and properly documented.
Step 2: Choose the Right Tax Return Form
- Company tax return (Form C): For firms registered as companies
- Partnership return: For partnerships
- Trust tax return: For firms structured as trusts
Download the latest form from the ATO website or lodge electronically via myGov or tax agent software.
Step 3: Calculate Your Taxable Income
Determine the net income after deducting allowable business expenses. Consider depreciation, rent, wages, utilities, and marketing costs.
Step 4: Apply the Correct Tax Rate
Use the appropriate company tax rate based on your firm’s eligibility under base rate entity rules.
Step 5: Lodge the Return
You can lodge your firm tax return:
- Online through myGov (linked to ATO)
- Using Standard Business Reporting (SBR) software
- Through a registered tax agent
The ATO recommends using registered agents to avoid errors and access extended deadlines.
Step 6: Pay Any Owed Tax
After assessment, pay any tax owed before the due date to avoid interest and penalties.

Avoiding Mistakes in Your Firm Tax Return
1. Incorrect Tax Rates
Using the wrong rate can trigger ATO audits. Ensure your firm falls under the right classification.
2. Omitting Income Streams
Declare all revenue sources, including overseas income.
3. Incomplete Expense Records
Inadequate documentation may lead to denied deductions.
4. Late Lodgement
Missing deadlines can lead to financial penalties. Use calendar reminders or work with a tax agent.
5. Not Reconciling Bank Accounts
Mismatches between reported income and bank statements raise red flags with the ATO.
Special Considerations for Different Firm Structures
Sole Trader Firms
Taxed at individual marginal rates. File using an individual tax return with business schedule.

The firm itself does not pay tax, but each partner reports their share of income on their personal return.
Companies

Trusts
