Filing Company Tax Returns in Australia: What Every Business Owner Needs to Know

Running a business in Australia comes with great opportunities but it also comes with responsibilities, especially when it comes to taxation. One of the most important annual tasks for any company is filing a company tax return with the Australian Taxation Office (ATO).

Filing accurately and on time ensures compliance, avoids penalties, and keeps your company in good standing. Whether you’re a startup founder, a growing business owner, or an international entrepreneur operating in Australia, here’s what you need to know about company tax returns.

1. Who Needs to File a Company Tax Return in Australia?

Every company that carries on a business or earns income in Australia is required to lodge a company tax return annually. This includes:

• Private limited companies (Pty Ltd)
• Public companies
• Foreign companies with an Australian presence
• Subsidiaries of international firms

Even if the company has made a loss or hasn’t earned income during the financial year, a tax return still needs to be submitted.

2. Key Filing Deadlines

The standard financial year in Australia runs from 1 July to 30 June. The due date for lodging a company tax return depends on how and when you lodge:

• If lodging through a registered tax agent – The deadline may be extended (typically between 15 January to 15 May of the following year).
• If lodging independently – The deadline is generally 31 October.

Late lodgment may result in penalties and interest, so it's essential to file on time.

3. Current Corporate Tax Rates

Understanding your applicable tax rate is crucial. For the financial year 2023–24:

• Base rate entities (BREs) – 25%
• (Companies with aggregated turnover less than $50 million and 80% or less of their income from passive sources.)
• Other companies – 30%

These rates apply to taxable income, not total revenue.

4. What’s Included in a Company Tax Return?

A company tax return includes:

• Company details (ABN, TFN, contact info)
• Financial statements summary
• Income details – Gross income, sales, other revenue
• Expense deductions – Salaries, rent, business expenses
• Tax offsets and rebates
• Calculation of taxable income and payable tax
• Franking account details (if applicable)

It’s submitted using the form Company tax return 2024, available through the ATO or via registered tax agents and accounting software platforms.

5. Preparing to File: What You Need

To file a tax return accurately, businesses need to maintain proper records throughout the year. Key documents and data include:

• Profit and Loss Statement
• Balance Sheet
• PAYG installment summaries
• BAS (Business Activity Statements)
• Depreciation schedules
• Employee payment summaries (STP data)

Using cloud-based accounting platforms like Xero, QuickBooks, or MYOB makes it easier to generate reports and stay audit-ready.

6. Lodging Your Tax Return

1. Through a Registered Tax Agent – Recommended for expert advice and lodgment extensions.
2. Online using Standard Business Reporting (SBR) enabled software – Ideal for digitally-savvy companies.
