When is Tax Return 2025? Key Australian Deadlines You Need to Know
- Jul 24
- 10 min read
When it comes to Aussie tax time, there's one date that looms large in everyone's mind: 31 October 2025. Let's get straight to it – this is the absolute deadline set by the Australian Taxation Office (ATO) for most people to lodge their own tax return for the financial year ending 30 June 2025.
This covers all the income you earned between 1 July 2024 and 30 June 2025.
Your Guide to Australian Tax Return Deadlines
Think of the period from 1 July to 31 October as the standard window for millions of Australians who handle their own tax affairs, usually through the ATO's myTax portal. Getting your head around this timeframe is the first step to a stress-free tax season.
But that date isn't the end of the story. There's a crucial alternative that gives you a lot more breathing room: using a registered tax agent like us.
By engaging a professional service like Baron Tax & Accounting before the 31 October deadline, you can often get a lodgement extension. It’s not uncommon for these extensions to push the deadline as far out as May of the following year, a standard arrangement the ATO provides to its registered agents.
Who the 31 October Deadline Affects
So, who needs to circle 31 October on their calendar? This is your deadline if you're lodging your tax return yourself, without a tax agent's help. It’s a good idea to start gathering your documents—like income statements, bank interest details, and receipts for any deductions—well in advance to avoid that last-minute scramble.
This typically applies to income from:
Salary and wages
Bank interest
Government payments
Dividends from investments
If you're dealing with investments, having a solid understanding of Australian investment taxes for stocks is vital, especially if you have a diverse portfolio. Reporting everything correctly is the key to staying compliant and avoiding headaches later.
To give you a clearer picture, here’s a quick summary of the key dates.
Key 2025 Tax Lodgement Dates at a Glance
This table breaks down the most important deadlines for individual taxpayers based on how they choose to lodge.
Lodgement Method | Applies To | Key Deadline |
|---|---|---|
Self-Lodgement | Individuals lodging their own tax return via myTax or by paper. | 31 October 2025 |
Registered Tax Agent | Individuals using a tax agent like Baron Tax & Accounting. | Varies (often extended to 15 May 2026) |
New Tax Agent Registrations | You must engage a tax agent before 31 October 2025 to qualify for extensions. | 31 October 2025 |
Remember, these dates are your guide to staying on the right side of the ATO. Knowing these deadlines is the first step, but proactive planning is what really makes a difference.
Getting an early idea of your potential refund can be a great motivator, too. Why not use our quick tax refund calculator to see where you might stand? It's a simple way to get a preview of your tax outcome.
Securing a Tax Lodgement Extension
Is the 31 October deadline feeling a bit tight? There’s a smart, built-in solution that savvy taxpayers use every year. The most reliable way to get an extension isn’t by begging the ATO for special consideration; it’s by partnering with a registered tax agent before the deadline hits.
This isn’t some secret loophole. It's a structured program the ATO has in place. When you engage a professional like Baron Tax & Accounting, you become part of our lodgement program, which automatically gives you access to a completely different set of deadlines.
How Tax Agent Extensions Work
The process is surprisingly simple. Once you sign on with a registered tax agent before 31 October 2025, we notify the ATO that we’re handling your return. That single action moves you onto our extended schedule, which can push your final due date all the way out to 15 May 2026.
Of course, it’s not a free pass for absolutely everyone. Your eligibility generally hinges on a few key things:
A Good Lodgement History: You need a solid track record of filing previous tax returns and activity statements on time.
No Outstanding Tax Debts: The ATO expects you to have paid any previous tax liabilities or have a formal payment plan in place.
Timely Engagement: This is the big one. You must be on the tax agent's client list before 31 October. If you wait until after that date, you’ve missed the window for the standard extension.
Engaging a tax agent turns the deadline from a hard stop into a strategic checkpoint. It gives you the breathing room you need to gather all your documents, meticulously check for every last deduction, and make sure your return is as accurate as possible to maximise your potential refund.
By understanding how this system works, you can turn anxiety about the 'when is tax return 2025' deadline into a well-managed plan. It’s all about working smarter, not harder, to meet your obligations without that last-minute panic.
What Happens If You Miss the Tax Deadline
Let's be honest, that 31 October deadline can sneak up on anyone. But simply ignoring it and hoping your tax obligations will vanish isn't a strategy. Facing a missed deadline is stressful, but understanding what the Australian Taxation Office (ATO) does next is the key to managing the situation and keeping the financial fallout to a minimum.
When you don’t lodge your 2025 tax return on time and you have a tax bill to pay, the consequences are very real. The ATO often applies penalties and interest charges that can quickly grow. As you can explore further in this tax deadline guide, these penalties are designed to get worse the longer you wait, which makes taking action—even late action—so important.
Understanding Penalties and Interest
If you lodge late, the ATO can hit you with two different charges.
First up is the Failure to Lodge (FTL) penalty. This is a fine calculated based on how late your return is. The ATO applies one penalty unit—currently valued at $330 as of 1 July 2025—for every 28-day period (or part of one) that your return is overdue. This can stack up to a maximum of five penalty units.
The second charge is the General Interest Charge (GIC). Think of this like a taxi meter running on any unpaid tax you owe. The interest adds up daily on your outstanding balance until you've paid it off completely. It’s how a small tax debt can balloon into a much bigger headache.
The bottom line is this: these penalties are there to encourage everyone to lodge on time. The longer you put it off, the more it's likely to cost you. Being proactive, even after you've missed the date, is always the best way to keep those costs in check.
What to Do If You're Behind
If you've found yourself on the other side of the deadline, the worst thing you can do is bury your head in the sand. Don't panic. The ATO is usually far more understanding with people who voluntarily come forward to sort things out. Your best move is to get that overdue return lodged as quickly as possible.
It's also worth checking if you even needed to lodge a return in the first place. If your income for the year was below the tax-free threshold, you can simply submit a 'Return Not Necessary' advice form to the ATO. This is a quick and easy way to let them know you don't need to file, which stops any automated reminders or penalties from being sent your way. This is a vital step when figuring out your obligations around the when is tax return 2025 deadlines.
Deadlines for Businesses and Other Entities
While the 31 October deadline is a big deal for individual taxpayers, it’s really just one piece of a much larger puzzle. For businesses, trusts, and other complex entities, the Australian tax calendar looks quite different. If you're a business owner asking "when is my tax return due in 2025?", you need to look well beyond the standard individual lodgement date.
The reality is that business finances are inherently more complex. Whether you’re operating as a sole trader, a partnership, or a company, the ATO has a different set of rules and timetables for you.
Key Business Tax Dates
Your tax obligations aren't a once-a-year event. Staying on the right side of the ATO means managing several key dates throughout the financial year. The most common ones you'll need to juggle are:
Business Activity Statements (BAS): Think of these as your quarterly check-in with the ATO. They cover things like GST and PAYG withholding. The due dates usually fall on the 28th of the month after the quarter ends (so, 28 October, 28 February, 28 April, and 28 July).
Pay As You Go (PAYG) Instalments: These are your regular prepayments towards your business's annual income tax bill. The deadlines for these generally follow the same quarterly cycle as your BAS.
Keeping on top of these regular lodgements is absolutely essential for managing your cash flow and meeting your compliance duties. To take the pressure off, many business owners turn to experts for their business tax and accounting needs.
Navigating business tax is like conducting an orchestra. The annual return is the final performance, but hitting every note correctly with your BAS and PAYG instalments along the way is what creates a harmonious financial picture.
Australia's financial year runs from 1 July to 30 June. But while individuals get until October to file, many companies operate on a completely different schedule. For lots of corporate entities, their tax returns are actually due by the 15th day of the seventh month after their financial year ends, which for many means a 15 January deadline. It’s a fundamental part of how corporate tax administration works in Australia.
A registered tax agent can help you manage this entire calendar, making sure you hit every single deadline without the stress.
Practical Steps to Prepare for Tax Time
Knowing the tax deadline is one thing, but being ready for it is a whole different ball game. Let’s break down what you need to do, turning that looming date into a simple, manageable plan. A smooth tax season always starts with good preparation, helping you avoid that last-minute panic when you realise the 31 October deadline is just around the corner.
By tackling the process in a few straightforward steps, you can approach your 2025 tax return feeling organised and confident. And it all begins with getting your paperwork in order.
Gather Your Essential Documents
Before you can even think about lodging, you need to pull together all your financial records from the last financial year (1 July 2024 to 30 June 2025). This is the absolute foundation of an accurate tax return.
Think of your document checklist like this:
Income Statements: This means your PAYG payment summary from any employers, details of government payments you've received, and statements for any bank interest earned.
Investment Records: Got shares? Sold some crypto or a property? You'll need the details on any dividends, capital gains, or losses.
Receipts for Deductions: This is where you can really make a difference to your return. Gather every receipt for work-related expenses—home office costs, car and travel expenses, uniforms, or self-education. Don't leave money on the table.
Think of preparing your tax return like baking a cake. Each document is a crucial ingredient. If you forget one, it could completely change the final result—and nobody wants a surprise tax bill instead of a refund.
DIY vs. Professional Help
Once all your documents are in a pile, you’re at a crossroads: do you lodge the return yourself or call in a professional?
Lodging on your own through myTax can work well if your financial situation is pretty simple. The risk, however, is that you might miss out on deductions you didn't know about or make a small mistake that catches the ATO's attention.
This is where engaging a tax professional gives you a serious advantage. An expert can spot deductions you’re entitled to, making sure your return is not only accurate but maximised. Plus, there’s the peace of mind that comes from having a professional double-check everything.
At Baron Tax & Accounting, we offer a range of expert tax preparation services to make your lodgement seamless and stress-free. Ultimately, the right path depends on your confidence, how complex your finances are, and what your time is worth.

Your Top Tax Deadline Questions Answered
When it comes to tax time, a few questions pop up again and again, especially when your situation isn't perfectly straightforward. Let's tackle some of the most common queries we hear about the 2025 tax return deadlines.
What If I’m Overseas When My Tax Is Due?
Jetting off overseas doesn't mean you can leave your tax obligations behind. If you're an Australian resident for tax purposes, the ATO still expects you to lodge on time.
The simplest way to handle this is to get organised before you go. By signing up with a registered tax agent like us before the 31 October deadline, we can lodge for you and secure an extension, giving you one less thing to worry about while you're away.
Can I Get An Extension If I’m Lodging Myself?
It’s very rare for the ATO to grant an extension directly to individuals lodging their own tax returns. Generally, they only consider this for truly serious and unexpected situations, like a severe illness or being impacted by a natural disaster.
For most people, the only reliable way to get more time is to appoint a tax agent before the deadline. This gives you access to their later lodgement dates.
I Haven’t Lodged a Tax Return for Several Years. What Should I Do?
Falling behind on your tax returns can feel like a huge weight on your shoulders, but it’s a problem that can definitely be solved. The most important thing is to take action now instead of putting it off any longer.
A tax professional can confidentially help you get everything in order. We’ll prepare and lodge all your overdue returns and communicate with the ATO on your behalf, often helping to get penalties reduced or even waived.
Getting professional help for overdue returns shows the ATO you’re serious about getting back on track. It's the best way to sort out the situation, minimise financial stress, and move forward.
