Preparing and lodging an individual tax return in Australia can seem daunting—but the online service myTax, provided by the Australian Taxation Office (ATO), is designed to make the process more streamlined, accessible and efficient. In 2026, with many taxpayers juggling work, study or side‑gigs, knowing how to use myTax effectively means avoiding mistakes, getting refunds faster and staying on the right side of your tax obligations.
This article walks through a clear, step‑by‑step guide to lodging your tax return using myTax—from linking your account, checking pre‑filled data, entering income and deductions, to submitting and tracking your assessment. Along the way it offers practical tips, common pitfalls, and how to make this year’s return smoother and more effective.
Why Use myTax in 2026?
Using myTax offers several advantages. The ATO notes that the service is available 24 hours a day, 7 days a week, and most refunds lodged online arrive within two weeks.
Key benefits include:
Pre‑filled data from employers, banks and government agencies is automatically imported when available, reducing manual input.
You can lodge from most devices—computer, tablet or smartphone—once you link your myGov account.
It’s free to use for most individuals, and you receive an electronic lodgment receipt instantly.
Given these advantages, self‑lodging via myTax is an increasingly appealing option—especially for individuals with straightforward income and deductions. Of course, more complex affairs may still warrant a tax agent.
Step‑by‑Step Guide to Lodging with myTax
1. Prepare Before You Begin
Before logging into myTax:
Ensure your myGov account is active and linked to the ATO. You’ll need to link the ATO service within myGov to use myTax.
Collect necessary information: your Tax File Number (TFN), bank account details, income statements (PAYG), interest/dividends statements, private health insurance details, and receipts for deductions (e.g., work‑related, charitable donations, self‑education).
Review changes for the 2026 tax year (income thresholds, deduction rules, offsets) so you’re aware of new rules.
2. Access myTax
Log in to myGov, select the ATO service and choose “Lodge your tax return” via myTax.
You will be prompted to choose the income year (e.g., 2025‑26) and confirm your personal details.
3. Review Pre‑filled Data
One of myTax’s strengths is its pre‑fill capability. The ATO states that most information from employers, financial institutions, and government agencies will be available to pre‑fill your return.
What to check:
Your name, address, TFN and myGov account details.
Pre‑filled income: wages (PAYG), bank interest, dividends, government benefits.
Private health insurance or help‑loan (HECS/HELP) debt details.
If any pre‑filled item is incorrect, you can edit it—just keep your records in case the ATO reviews it later.
4. Enter Additional Income
Even with pre‑fill, you may need to add extra income such as:
Cash income, side gigs or gig‑economy earnings.
Foreign income or overseas investment income.
Business, rental or trust income (if applicable).
Navigate to the “Income” section and follow prompts to “Add/Edit” each income type. If you fail to declare all taxable income, you may receive a data‑matching letter from the ATO.

5. Claim Deductions & Offsets
The “Deductions” section is where you can reduce taxable income legitimately. Key points:
Only claim work‑related expenses if you incurred them yourself, not reimbursed, and kept valid records (receipts, logs).
Common claims: work‑from‑home expenses (fixed rate or actual cost), car/travel if used for work, uniforms/protective clothing, self‑education.
Tax offsets may include: low‑income tax offset, private health insurance rebate, seniors and pensioners tax offset.
Use the “Review” screens to ensure everything is entered correctly before moving on.
6. Review & Submit
Before lodging:
Use the “Review” stage to check for any errors or missing data.
Confirm your bank account details for your refund or tax‑owed amount.
Submit the return; you will receive an electronic lodgment receipt with a number.
7. Track Lodgement & Refund
Once lodged, most online returns are processed within about two weeks.
You can track status via the ATO’s online services or the ATO app. Make sure you keep documents for at least five years in case of audit.
8. Correcting or Amending Returns
If you realize you made a mistake:
Use myTax to amend your return online if eligible.
Alternatively, contact the ATO for instructions on lodging a variation or objection if you disagree with an assessment.
Common Mistakes & How to Avoid Them
Not linking myGov to the ATO – Without linking, you cannot access myTax.
Ignoring pre‑filled data – Failing to review leads to incorrect returns.
Claiming invalid deductions – The ATO emphasizes you must have spent the money yourself and kept records.
Missing income from side gigs/foreign sources – Even small amounts must be declared.
Using outdated information or rates – Always verify the year you’re lodging and any rule changes.
Filing late – The due date for individuals who lodge themselves is 31 October each year.
By avoiding these mistakes, taxpayers can reduce the risk of audits, delays or amendments.
Tips to Maximize Your Return in 2026
Keep records year‑round – Use tools like the ATO’s myDeductions feature in the ATO app to store receipts and logs.
Review tax offsets and rebates – If you had private health cover, lived rurally, or paid student loans (HELP/VSL), ensure they’re included.
If you’re an international resident or student, check the rules around residency status and allowable deductions.
Consider using a tax agent if your affairs are complex—some studies show agents may find more deductions than those going solo.
Lodge early – Faster lodgment helps refund timing and reduces stress.
