Australia’s 2025–26 Tax Return Deadline Is Approaching
The deadline for Australians who prepare and lodge their own 2025–26 individual income tax returns is approaching, with the final date falling on Monday, 2 November 2026.
The usual deadline is 31 October. However, because that date falls on a Saturday in 2026, the deadline moves to the next business day.
According to reporting by news.com.au, approximately nine million tax returns had been received by the ATO at the time of publication, while around two million were still outstanding. The ATO has encouraged taxpayers not to leave lodgement until the final days, when rushing can increase the risk of errors and missing information.
For individuals who have not yet lodged, the priority should be to establish what information is needed, confirm the applicable deadline, and submit an accurate return as soon as practical.
Taxpayers should also remember that not everyone has the same lodgement arrangements. People using a registered tax agent may qualify for a later date under the agent’s lodgement program, subject to the relevant conditions.
What Is the ATO Failure-to-Lodge Penalty?
The ATO can impose a failure-to-lodge penalty when a required tax return or other document is not submitted by its due date.
For individuals, the penalty is generally calculated using penalty units for each 28-day period, or part of a period, that the return remains overdue. At the current penalty-unit value of $364, the amount can reach $1,820 after five penalty units.
The penalty structure is designed to encourage taxpayers to meet their reporting obligations. The amount and application of a penalty can depend on the taxpayer’s circumstances and the applicable rules.
Importantly, the maximum penalty is not automatically charged to every person who lodges late. The ATO may consider factors such as the length of the delay, the taxpayer’s lodgement history, and the circumstances surrounding the failure.
However, taxpayers should not assume that a short delay or an expected refund means they are exempt from their lodgement obligations. The safest approach is to lodge on time or contact the ATO if they anticipate difficulty meeting the deadline.
What If You Are Due a Tax Refund?
Some taxpayers delay lodging because they believe there is little urgency if they expect a refund rather than a tax bill.
However, whether a person needs to lodge a return depends on their individual circumstances and tax obligations. An expected refund should not be treated as automatic permission to lodge late.
If you believe you are entitled to a refund, submitting an accurate return promptly can help bring your tax affairs up to date and allow the ATO to assess the result.
Can You Get More Time to Lodge Your Tax Return?
Some taxpayers may qualify for a later lodgement date if they use a registered tax agent who participates in the ATO’s lodgement program.
For the 2025–26 tax return, eligible taxpayers may be able to access a later deadline, potentially as late as 15 May 2027, depending on the agent’s lodgement schedule and the taxpayer’s circumstances.
Taxpayers who want to use this option should contact a registered tax agent before 31 October 2026 and confirm that they have been added to the agent’s client list in time. Eligibility may also depend on whether previous tax returns are up to date. Simply booking an appointment or assuming an extension applies is not enough.
Before relying on a later deadline, ask the agent to confirm the applicable date for your circumstances.
If you are already overdue, do not assume that engaging an agent will automatically resolve the issue or remove any existing penalties. Discuss your position with the agent or contact the ATO directly.
Common Tax Return Mistakes the ATO Is Watching
Meeting the deadline is important, but taxpayers should not sacrifice accuracy to submit their returns quickly.
The ATO has highlighted areas where mistakes can occur, including work-related deductions and income that may not be fully reported. Taxpayers should take the time to check their information and retain evidence for their claims.
Claiming Work-Related Expenses Without Adequate Evidence
Work-related deductions can reduce taxable income when the expenses meet the relevant requirements. However, not every purchase made by someone who is employed is deductible.
Generally, a taxpayer must have incurred the expense, have a sufficient connection between the expense and earning their income, and meet the applicable substantiation requirements. Reimbursements and private-use portions may affect whether a deduction is available.
Examples of expenses that may require careful review include:
- Working from home expenses.
- Mobile phones and internet costs.
- Professional subscriptions and union fees.
- Work-related travel.
- Equipment and other items used partly for work and partly for private purposes.
If an item is used for both work and private purposes, only the eligible work-related portion may be deductible. Taxpayers should not automatically claim the full cost simply because the item is sometimes used for work.
For working-from-home claims, check the current ATO rules, the method being used, and the records required to support the calculation.
Assuming Every Purchase Is Tax-Deductible
A common misconception is that buying something before the end of the financial year automatically creates a tax deduction.
In reality, the expense must meet the applicable requirements. The tax treatment may also depend on whether the item is a current expense, an asset, a private purchase, or something that needs to be depreciated over time.
For example, a laptop used for both employment and personal activities may require apportionment. A business asset may be subject to specific depreciation or other deduction rules rather than being immediately deductible in full.
Before claiming an expense, establish its purpose, the relevant tax treatment and the evidence required.
Forgetting Income from Side Hustles
Income earned outside a person’s main job may still need to be reported.
Depending on the circumstances, this can include income from activities such as ridesharing, delivery of work, freelancing, online selling, short-term accommodation or other income-generating activities.
Tax treatment depends on the nature of the activity. A business, a hobby, occasional sales of personal possessions and investment income can have different consequences.
Taxpayers should review their records and information from relevant platforms to determine what must be included in their returns.
Failing to Report Investment or Asset Sales
Income and gains from investments or asset disposals may also need to be considered.
Depending on the transaction, this may include dividends, interest, rental income, capital gains from shares or cryptocurrency, and gains from selling property.
The tax treatment depends on the asset, the transaction, and the taxpayer’s circumstances. For example, selling an investment asset may create a capital gains tax event, while other transactions may be treated differently.
Review relevant transaction records and do not assume that the ATO will automatically include every item in your return.
Check Your Pre-Filled Tax Information Carefully
The ATO may pre-fill information in a tax return using data received from employers, financial institutions, government agencies, and other reporting entities.
This can make preparing a return easier, but pre-filled information should not be accepted without checking it.
Information may be incomplete, delayed, or incorrect. Taxpayers should compare it with their own records and ensure that all required income and deductions have been included.
Before lodging, check the following:
- Employment income and tax withheld.
- Interest and dividend income.
- Government payments, where applicable.
- Private health insurance details, if relevant.
- Information about investment income and asset disposals.
- Work-related expenses and supporting records.
- Any income earned through additional work or online platforms.
If information is missing, investigate whether it needs to be added. If something appears incorrect, seek clarification before submitting the return.
Taking time to review these details can help reduce the risk of an amended return, an ATO review, or an unexpected tax outcome.
What Should You Do If You Cannot Lodge on Time?
If you know that you will not be able to lodge the applicable deadline, act early rather than ignore the issue.
First, establish why you cannot lodge. You may be waiting for documents, dealing with an unusual tax situation or experiencing personal circumstances that make it difficult to complete the return.
Next, consider contacting a registered tax agent or the ATO to discuss the available options.
Depending on the circumstances, it may be possible to request additional time or obtain assistance with meeting your obligations. Any extension or deferral should be confirmed rather than assumed.
If you are already late, lodge as soon as you reasonably can and address any outstanding communication from the ATO. Delaying further may make the situation more difficult to resolve.
If you cannot afford to pay an amount of tax owing, remember that lodging and paying are separate issues. Do not automatically delay lodging because you are worried about the amount due. Contact the ATO to discuss payment options and your circumstances.
Be Careful When Choosing a Tax Return Preparer
Taxpayers who need help preparing their returns should check that the person providing tax agent services is appropriately registered.
The ATO has warned taxpayers about unregistered preparers who may encourage inflated deductions or make promises about guaranteed refunds. Reporting the current tax season indicated that more than 10,000 returns suspected of being prepared by unregistered preparers had been stopped, involving more than $170 million in deductions.
Be cautious if a preparer:
- Promises a guaranteed refund before reviewing your circumstances.
- Encourages you to claim expenses you did not incur.
- Suggests that records are unnecessary.
- Offers deductions that appear too good to be true.
- Claims they can guarantee faster ATO processing.
You can check a tax practitioner’s registration through the Tax Practitioners Board.
Using a registered tax agent can help you understand your obligations, identify eligible deductions, and prepare an accurate return. However, taxpayers should provide complete information and review their returns carefully before authorising lodgement.
A Practical Checklist Before Lodging Your 2025–26 Tax Return
Before submitting your return, take time to complete a final review.
Confirm your deadline. If you are lodging your own individual return, note the 2 November 2026 deadline. If you are using a tax agent, confirm your individual lodgement date.
Gather your records. Collect relevant income statements, receipts, invoices, investment records, and supporting documents.
Review pre-filled information. Check that the details supplied by the ATO are correct and complete.
Check the deductions carefully. Claim only expenses that meet the relevant requirements and retain the required evidence.
Include all relevant income. Consider employment, investments, side activities, and other sources that may need to be reported.
Review the final return. Check names, figures, bank details, and other information before lodging.
Keep copies of your records. Retain the information needed to support your return in accordance with the applicable record-keeping rules.
If your tax affairs are complex or you are unsure how an item should be treated, seek professional advice before lodging.

Final Thoughts
The approaching ATO tax return deadline is a reminder for Australians to review their tax obligations, organise their records and lodge accurately.

Taxpayers should also pay attention to the accuracy of their returns. Work-related expenses must meet the relevant requirements; all reportable income should be considered, and pre-filled information should be checked rather than accepted without review.
