Filing your company tax return can feel overwhelming, but it doesn’t have to be. We’re here to walk you through the process step-by-step, making it as simple and stress-free as possible. Whether you’re running a small business, managing a charity, or working in healthcare or trades, understanding how to lodge your company tax return correctly is essential. Let’s dive in and make this task manageable together.
Understanding Company Tax Lodgement
When we talk about company tax lodgement, we’re referring to the process of submitting your company’s annual tax return to the Australian Taxation Office (ATO). This return reports your company’s income, expenses, and tax payable for the financial year. Lodging your tax return on time and accurately is crucial to stay compliant and avoid penalties.
Companies are taxed differently from individuals, so it’s important to know the specific requirements. For example, companies pay a flat tax rate on their taxable income, which varies depending on their size and turnover. Keeping good records throughout the year makes this process much easier.
Here are some key points to keep in mind:
Your company must lodge a tax return every year, even if it didn’t make a profit.
You’ll need to report all income, including sales, investments, and any other earnings.
Deductible expenses like wages, rent, and business-related costs can reduce your taxable income.
If your company has employees, you’ll also need to report PAYG withholding amounts.

What is the due date for filing a corporate tax return?
Knowing the due date for your company tax return is vital to avoid late fees and penalties. Generally, the due date depends on whether you lodge your return yourself or use a registered tax agent.
If you lodge yourself: The due date is usually 15 July following the end of the financial year (which ends 30 June).
If you use a registered tax agent: You may get an extended deadline, often until March of the following year, but you must register with the agent before 31 October.
It’s important to plan ahead and gather all necessary documents early. This includes financial statements, bank records, and any other relevant paperwork. If you miss the deadline, the ATO can impose penalties, so staying organised is key.
If your company has a substituted accounting period (SAP), the due date may differ, so check with your accountant or the ATO for specific details.
How to Prepare for Company Tax Return Lodgement
Preparation is the foundation of a smooth tax return process. Here’s how we recommend getting ready:
Organise your financial records: Collect all invoices, receipts, bank statements, and payroll records.
Reconcile your accounts: Make sure your accounting software or ledger matches your bank statements.
Review your expenses: Identify which costs are deductible and ensure you have supporting documentation.
Calculate your income: Total all revenue streams, including sales, interest, and other income.
Check for tax offsets and credits: Some companies may be eligible for tax incentives or rebates.
Consult your accountant: If your financial situation is complex, professional advice can save you time and money.
Using accounting software can simplify this process by automating calculations and generating reports. Many small to medium enterprises find this especially helpful.

Common Mistakes to Avoid When Lodging Your Company Tax Return
We’ve seen many companies make avoidable errors that cause delays or trigger audits. Here are some common pitfalls to watch out for:
Missing the deadline: Late lodgement can lead to penalties and interest charges.
Incorrect or incomplete information: Double-check all figures and details before submitting.
Not reporting all income: Even small amounts must be declared.
Claiming non-deductible expenses: Only legitimate business expenses can be deducted.
Failing to keep records: The ATO requires you to keep records for at least five years.
Ignoring changes in tax law: Stay updated on any new rules that might affect your return.
Taking the time to review your return carefully can save you headaches later. If you’re unsure about anything, don’t hesitate to ask a tax professional.
