The end of the financial year (EOFY) in Australia ends on June 30, 2026 and marks a crucial deadline for submitting tax returns and finalising financial records. According to the Australian Taxation Office (ATO), this period is vital for meeting compliance obligations and maximising lawful deductions and refunds. Whether you’re an employee lodging an individual tax return in Australia or a business owner handling complex records, doing your preparation early can save time, reduce stress, and improve outcomes.
Why Early EOFY Preparation Matters
Preparing early for EOFY 2026 gives you time to organise documents, correct issues, and discover opportunities to maximise your refund.
Avoid stress and last‑minute errors
Rushing your tax return can lead to mistakes that trigger ATO reviews or adjustments. Systematic preparation helps you double‑check income sources, deductions, and records.
Maximise lawful deductions
Proper bookkeeping and record‑keeping help you claim every deduction you’re entitled to. This is often overlooked by individuals and small business owners who wait until the last minute. A clear EOFY bookkeeping checklist helps track receipts, invoices, and expense categories that can reduce taxable income.
Improve refund timing
Preparing early allows you to lodge as soon as the tax returns open, helping you receive a tax refund in Australia sooner if you’re eligible. Early lodgment may also prevent delays created by ATO processing backlogs.
The ATO offers many preparation resources, including an EOFY checklist and guidance for businesses on record‑keeping and deductions.

If you have earned income or operated a business during the 2025–26 financial year, you’ll likely have obligations at EOFY.

Employers
Employers need to finalise wages, report any fringe benefits, and make sure PAYG withholding and superannuation are lodged correctly.
Key Dates and Deadlines for EOFY 2026
Deadlines depend on how you lodge and what type of taxpayer you are. Missing deadlines can lead to penalties and interest on tax payable.
Individual Tax Return Deadlines
- Standard lodgment deadline: Usually October 31, 2026, if you lodge your individual tax return in Australia yourself.
- If you use a registered tax agent and you’re on their client list by October 31, you typically get extended time to lodge. Confirm due dates with your agent.
Small Businesses and Sole Traders
- Lodging may align with your tax agent’s schedule once you’re on their roster by October 31.
- Business Activity Statements must be filed quarterly or monthly, with final quarters often due by the same time as EOFY requirements.
PAYG Withholding
Employers must finalise and report employee tax statements and meet PAYG withholding 2026 lodgment and payment deadlines. The ATO sets specific due dates for annual reporting.
Consequences of Late Submission
Lodging late without an approved extension can result in failure‑to‑lodge penalties, interest charges on tax owed, and delays in refunds.
Preparing Your Individual Tax Return Australia
Filing an EOFY tax return can seem daunting, but breaking it into steps helps.
Step 1: Gather Income Records
Collect all sources of income from the financial year:
- Income statements reported by employers (available via myGov/AusKey).
- Bank interest and dividends
- Rental property income
- Business or freelance earnings
- Capital gains from investment sales
Having accurate records reduces errors and audit risk.
Step 2: Identify Eligible Deductions
You can claim deductions that are directly related to earning your income. Common deductible items include:
- Work‑related expenses (uniforms, tools, travel) if not reimbursed
- Self‑education expenses related to your current job
- Home office running costs (if you work from home)
The ATO provides detailed advice on allowable deductions and what records you need to keep. Too often, taxpayers miss eligible deductions. Organised records throughout the year make this easier.
Step 3: Use Tools or Software
You can lodge your return:
- Online through myGov, linked to the ATO
- Using tax preparation software approved by the ATO
- Through a registered tax agent
Each method has pros and cons. Online lodgment is free and direct, but a tax agent can help identify deductions and handle complexity.
Step 4: Check Records Before Lodgment
Review your figures. Common errors include transposed numbers, missed income sources, or incorrectly claimed deductions. Double‑checking reduces the chance of amendments later.
Make sure you know exactly which documents are required for your tax return to avoid mistakes and future corrections.

Tax Offsets and Credits

Use of a Registered Tax Agent
Many Australians engage a registered agent to ensure they claim all entitlements legally and avoid errors. If you choose this route, ensure you enrol with them early in the lodgment season so they can secure extended deadlines.
Lodging Tax Returns in 2026: Step‑by‑Step

FAQs
What are the benefits of lodging early, even if I don’t expect a refund?
Lodging early helps you avoid penalties if you owe tax, gives more time to organise payments, and reduces the chance of errors caused by rushed submission at the deadline.
Do I need to declare foreign income on my 2026 tax return?
Yes, all Australian residents for tax purposes must declare worldwide income, including foreign salary, interest, dividends, or property earnings. Certain tax treaties may provide relief from double taxation.
How do PAYG installments affect my tax return?
If you pay PAYG installments, these amounts are credited against your final tax liability. Accurate reporting ensures you neither underpay nor overpay, which can prevent interest charges or unnecessary refunds.
Can I amend my 2026 tax return after lodgment?
Yes, if you discover an error or omission after submitting your EOFY 2026 tax return, you can request an amendment through the ATO. Typically, individuals have up to two years to amend a return for most cases, but businesses may have different timeframes.
How does pre-filling information in myGov work?
myGov pre-fills your tax return with information the ATO already has, such as salary, bank interest, dividends, and some government payments. However, you are responsible for reviewing all entries, adding missing deductions, and verifying accuracy.
