If you want to lodge tax return online in 2026, the fastest and easiest way is through myTax via your myGov account, linked to the Australian Taxation Office.
Most people can complete the entire process in under 30 minutes once their income statement is “tax ready,” and refunds for online lodgments typically arrive within about two weeks.
This guide walks you through exactly how to lodge your tax return online, what you need before you start, key 2025–26 deadlines, common deductions people miss, and when it’s worth getting help from a registered tax agent instead of doing it yourself.
Who Needs to Lodge a Tax Return in 2026?
Most Australian residents who earned income during the 2025–26 financial year need to lodge a tax return.
If you’re unsure, the ATO’s “Do I need to lodge?” tool can confirm your obligation in a couple of minutes. If you earned no income or were below the tax-free threshold, you may only need to submit a non-lodgment advice instead of a full return.
This applies slightly differently depending on your situation Australian residents, non-residents, first-time lodgers, students, sole traders, and expats lodging from overseas all have different rules. I
f your tax affairs are even slightly complex, it’s worth reviewing the taxation servicesavailable so you lodge correctly the first time rather than risk an amended return later.
Key ATO Dates and Deadlines for 2025–26
The lodgment period for self-lodgers runs from 1 July to 31 October 2026. If you’re lodging tax return online yourself (not through an agent), 31 October 2026 is your hard deadline to avoid late lodgment penalties and interest charges. If you register with a tax agent before this date, you generally get an extended deadline, often into May 2027.
Refund timing also depends on how you lodge. Online returns through myTax are usually processed within about two weeks, while paper tax returns can take up to 50 business days.
This timing difference alone is one of the strongest reasons people choose to lodge income tax return online rather than mail a paper form.
What You Need Before You Lodge Online
Before you lodge a tax return online, gather the following:
- A myGov account linked to ATO online services
- Your Tax File Number (TFN)
- Your income statement (wait until it shows “Tax ready” status, usually populated via Single Touch Payroll)
- PAYG withholding summaries, if applicable
- Private health insurance statement
- Records of work-related deductions receipts, invoices, and logs for things like working-from-home hours, travel, tools, and uniforms
- An Australian bank account for your refund
Having these ready before you start means you won’t be stuck mid-form chasing documents, which is the most common reason people abandon their return halfway through.
How to Lodge Your Tax Return Online with myTax (Step-by-Step)
Here’s exactly how to lodge tax return online using the ATO’s free myTax system:
1. Create or log in to your myGov account. If this is your first time, you’ll need to set up a myGov account and verify your identity.
2. Link myGov to the ATO. Go to the Services tab in myGov and link the Australian Taxation Office. You’ll need details like your TFN and previous notice of assessment to verify the link.
3. Open ATO online services. Once linked, click through to “Manage tax returns” from the ATO online services menu.
4. Start your individual tax return for the 2025–26 income year. Select myTax and begin a new return.
5. Review your pre-filled tax return data. The ATO automatically pulls in information from employers, banks, and health funds. Check this pre-fill information carefully it’s a great starting point, but it isn’t always complete or accurate.
6. Add and edit deductions. This is where most refund value is won or lost. Add any work-related expenses, donations, or self-education costs not already included.
7. Check offsets and levies. Confirm details like the low income tax offset, Medicare levy, and Medicare levy surcharge are applied correctly.
8. Sign and lodge. Once everything looks right, submit your return electronically.
9. Wait for your notice of assessment. You’ll receive this from the ATO confirming your refund or any amount owing, usually within about two weeks for online lodgments.
This process is the standard way the Australian Taxation Office lodge tax return online pathway works for most individuals, and it’s free to use directly through myTax.
Common Deductions and Offsets Most People Forget
When you lodge your tax return online, it’s easy to miss deductions that could boost your refund. Commonly overlooked items include:
- Work-from-home running expenses (electricity, internet, depreciation on equipment)
- Self-education costs directly related to your current role
- Personal superannuation contribution deductions
- Union fees and professional memberships
- Vehicle and travel expenses for work purposes
- HELP/HECS repayment thresholds, which affect your overall tax position
- Franking credits, if you hold Australian shares
Keeping proper records throughout the year not just at tax time makes claiming these far easier and reduces your audit risk. If you’re a small business owner or sole trader, it’s also worth looking at year-round tax planning strategies rather than only thinking about deductions in October.
When You Should Use a Registered Tax Agent Instead
While lodging tax return online yourself works well for simple returns (single employer, standard deductions), it’s worth using a registered tax agent if you have investment income, crypto transactions, rental properties, business income, or multiple income sources. Agents can also access an extended lodgment deadline beyond 31 October.

UBS Accountants also offers local support, including teams based inAdelaide and Sydney, for individuals and businesses who’d rather have a professional handle the process end to end.
