How to get your financial records ready for the Australian Taxation Office

When it comes to EOFY preparation, your first step is ensuring your financial records are in order. This includes everything from employee payslips and super contributions to expense receipts and income statements.

Our EOFY checklist outlines every document and task you need to cover before the deadline.

When does the Australian financial year start and end?

The Australian financial year runs from 1 July to 30 June each year. Most business tax obligations, including goods and services tax (GST) and company income tax returns, align with this period.

To claim deductions and avoid penalties, you must ensure that all income and expenses are recorded accurately within this timeframe.

What financial records do I need to keep for tax time?

Keeping the right records is essential for EOFY. At a minimum, your business should retain:

Income and sales records
Expense receipts and invoices
Payroll and superannuation data
BAS (Business Activity Statement) lodgement summaries
Copies of lodged tax returns

These documents must be stored for at least five years, as required by the ATO.

What’s the difference between a tax return and a company income tax return?

A tax return refers broadly to the income declarations made by individuals, sole traders and other entities. A company income tax return is specific to incorporated businesses and includes different schedules, such as dividends, franking credits and losses.

Your obligations will vary depending on your business structure – which is why it’s important to prepare the correct documentation and lodge by the right deadlines.

Do I need a registered tax agent to lodge my tax return?

You’re not required to use a registered tax agent, but many small and medium businesses do. Tax agents can:

Ensure you meet key deadlines
Help you understand what business expenses are deductible
Lodge returns on your behalf
Minimise errors that could trigger an audit

Engaging a professional can reduce risk and give you peace of mind – especially during the busy EOFY season.

How does my business structure affect my tax obligations?

Your tax requirements depend heavily on your business structure:

Sole traders must lodge personal and business income together.
Partnerships and trusts must report income distributions correctly.
Companies must lodge separate company income tax returns.
Super funds have distinct lodgement rules and deadlines.

Your calendar should reflect the right dates for your structure – which is exactly what our downloadable calendar covers.

What business expenses can I claim at the end of the financial year?

The ATO allows businesses to claim deductions for eligible business expenses that relate directly to earning income. These may include:

Staff wages and superannuation
Rent and utility bills
Equipment and software
Business travel and training
Professional services, such as accounting or legal advice

To maximise your deductions, keep clear records and ensure payments are made before 30 June.
