If you lodge your own 2025–26 tax return, it's due Monday 2 November 2026. (31 October falls on a Saturday, so the ATO moves the date to the next business day.) Registering with a tax agent before 31 October 2026 can extend your deadline to 15 May 2027.
Doing your Australian tax return can feel confusing. There are dates to remember, rules to follow, and money you might be able to claim back. This 2026 Australian tax return guide explains it all in plain, simple words. No confusing terms. Just what you need to know before you lodge. This guide is general information only and doesn’t take into account your personal circumstances. For advice tailored to your situation, speak with a registered tax agent.
Key Dates for Your 2026 Australian Tax Return
| Milestone | Date |
|---|---|
| Income year ends | 30 June 2026 |
| Lodgment opens (myGov) | 1 July 2026 |
| Self-lodged deadline | 2 November 2026 |
| Deadline via registered tax agent* | 15 May 2027 |
Most accountants suggest you wait until late July to lodge. This gives your employer, bank and health fund time to send your details to the ATO.Lodging too early can mean your return is missing information.
Do You Need to Lodge a Tax Return?
Most people who earned money between July 2025 and June 2026 need to lodge a tax return. This includes employees, sole traders, freelancers and landlords.
Even if you earned less than the tax-free threshold, you may still need to lodge. If any tax was taken out of your pay, lodging is the only way to get that money back. You can check your own situation with the ATO’s Do I need to lodge a tax return?
If you truly had no income at all, you still need to tell the ATO. You do this by lodging a non-lodgment advice instead.
What You'll Need Before You Lodge
Getting your paperwork ready first makes lodging much faster. According to the ATO’s Preparing Your Tax Return page, you’ll generally need:
- Your bank account details (BSB and account number), so any refund can be paid to you.
- Your income statement or payment summaries from every employer — wait until it’s marked “tax ready” before you lodge.
- Receipts or statements for any expenses you plan to claim as deductions.
- Your spouse’s income (if you have one), and your private health insurance details if you have cover.
If you lodge online through myTax, the ATO confirms most of this information is pre-filled for you, so you’re less likely to miss something.
Tax-Free Threshold and 2025–26 Tax Rates
The tax-free threshold for Australian residents is $18,200. This means the first $18,200 you earn each year is not taxed at all. Above that, the ATO’s resident tax rates for 2025–26 are:
| Taxable Income | Tax Rate |
|---|---|
| $0 – $18,200 | Nil |
| $18,201 – $45,000 | 16c for each $1 over $18,200 |
| $45,001 – $135,000 | 30c for each $1 over $45,000 |
| $135,001 – $190,000 | 37c for each $1 over $135,000 |
| $190,001 and above | 45c for each $1 over $190,000 |
These rates come from the ATO’s tax rates for Australian residents page. On top of these rates, most people also pay a Medicare levy of 2% of their taxable income. Some low-income earners pay a smaller levy, or none at all, you can check your own amount with the ATO’s Medicare levy reduction page.
Non-residents don’t get the tax-free threshold. They pay tax from their very first dollar earned. One more thing to note: the ATO confirms the 16% rate is set to drop to 15% from 1 July 2026. That change applies to next year’s return, not the one you’re doing now.

Deductions You Might Be Missing
A deduction is money you spent for work that you can subtract from your income before tax is worked out. Here are some common ones people forget:
- Work-related expenses – tools, uniforms, union fees, and the work part of your phone and internet bills.
- Working from home costs – the ATO’s fixed rate method lets you claim 70 cents for every hour you worked from home in 2025–26. This covers power, phone, internet and stationery. You need a record of your actual hours, kept as you go — the ATO does not accept guesses.
- Self-education – courses that are directly linked to your current job.
- Income protection insurance premiums paid outside your super fund.
- Investment property costs – loan interest, agent fees, and repairs.
Every deduction needs a record or a receipt. If you can’t show proof, it’s safer to leave it out and speak to a registered tax agent about it instead.
What Happens If You Lodge Late
If you miss your lodgment date, the ATO can charge a Failure to Lodge penalty. This works out to one penalty unit for every 28 days you’re overdue, up to a maximum of five units.
One penalty unit is now $364, so the biggest fine you could face is $1,820. You can check this figure yourself on the ATO’s penalty units page. If you owe tax and don’t pay it on time, interest also builds up daily on the amount you owe. You can read more on the ATO’s Failure to lodge on time penalty page.
The good news: the ATO usually doesn’t fine people whose late return leads to a refund or a nil result. The pressure falls mainly on people who owe money and keep putting it off.
What Happens If You Lodge Late
Lodging your own return through myTax works well if your tax affairs are simple. This means one job, no investments, and standard work deductions.
Once you add rental income, shares, several jobs, or overdue past returns, things get more complex. A registered tax agent can help make sure everything is claimed correctly and give you until 15 May 2027 to lodge, rather than November.
The Bottom Line
Your 2025–26 tax return is due on 2 November 2026 if you lodge it yourself, or 15 May 2027 through a registered tax agent. The tax-free threshold is $18,200, and the Medicare levy adds 2% for most people. Lodging late now risks a penalty of up to $1,820, plus daily interest on anything you owe.
Getting your Australian tax return right doesn’t need to be stressful. Keep good records, claim only what you can prove, and lodge before your deadline. If you’d rather have a professional check everything for you, the team at AAD Taxation can help you lodge your 2026 tax return correctly and on time.
Frequently Asked Questions

When do I need to lodge my 2026 tax return?
Monday 2 November 2026 if you lodge it yourself, since 31 October falls on a Saturday this year. A registered tax agent can extend this to 15 May 2027 if you’re on their books before 31 October 2026.

The ATO can charge a Failure to Lodge penalty of one penalty unit ($364) for every 28 days it’s overdue, up to a maximum of five units ($1,820). Daily interest also applies on any tax you owe.
How much can I claim for working from home?
For 2025–26, the ATO’s fixed rate method lets you claim 70 cents for every hour you worked from home. This covers power, phone, internet and stationery in one simple rate, but you need a genuine record of your hours for the whole year.
Should I lodge myself or use a registered tax agent?
Lodging yourself through myTax suits simple returns with one job and no investments. If you have rental income, capital gains, several income streams, or overdue returns, a registered tax agent can help you claim correctly. They can also give you until 15 May 2027 to lodge.
