Australia's tax deadline is almost here. If you lodge your own return, you must file by Monday, 2 November 2026. About 2 million returns are still unfiled, according to the ATO. A late return can cost up to $1,820 in fines.
Here is what the deadline means, and what to do now.
This is for the 2025-26 tax year. The tax year ended on 30 June 2026. Now the ATO wants every return in on time.
What happened
Most people who lodge their own return must file by 31 October. This year, 31 October is a Saturday. So the practical cut-off moves to Monday, 2 November.
That is the date in reports by YourLifeChoices and Particle.
The ATO says about 9 million returns are already in. Roughly 2 million are still to file. That is why "tax return" is trending in Australia this week.
If you use a tax agent, you may get more time. But you must be on that agent's books before 31 October. That rule comes from the ATO, via Particle and YourLifeChoices.
If you earned little or nothing, you still must tell the ATO. You can file a non-lodgement advice instead of a return. That advice says you did not need to lodge.

The fine is called a failure-to-lodge penalty. It applies when a return is late.
One penalty unit is now $364. That value started on 1 July 2026. It was $330 before that.
The fine grows in steps. If you are 1 to 28 days late, the fine is $364. If you are 29 to 56 days late, it is $728. If you are 57 to 84 days late, it is $1,092. If you are 85 to 112 days late, it is $1,456. If you are 113 days late or more, it hits the cap of $1,820.
The ATO does not always charge the fine. It often warns you first. It may skip the fine if your return gives a refund or a nil result.
But a refund does not guarantee you will avoid the fine. That is why eTax advises people to lodge as soon as they can.
Interest can add to the cost. If you owe tax and pay late, the ATO adds general interest. The rate is 11.51 per cent a year for October to December 2026. It compounds daily.
Since 1 July 2025, you can no longer claim that interest as a tax deduction.
You can also ask the ATO to drop the fine. You need a real reason and proof. Hardship, illness, or events outside your control can count.
Why it matters
The ATO is taking late lodgement more seriously. Successful prosecutions for not lodging rose by more than 80 per cent in one year. That is from 2024-25 to 2025-26, according to Kalkine, citing ATO figures.
Over two years, the ATO prosecuted more than 350 people and firms. Courts handed down more than 305 convictions. Fines topped $2.7 million.
But prosecution targets people who keep ignoring the ATO. It is not for one late return.
ATO Assistant Commissioner Tony Goding said: "Our message to the community is clear: deliberately ignoring your obligations comes at a significant cost."
Pre-filled data is another risk. The ATO pre-fills more than 100 million data items. The figures can be out of date or wrong.
Bank interest, investment income, and super details are the most common gaps. YourLifeChoices reports that the ATO warns people not to trust pre-filled data alone.
Research by H&R Block found a warning sign. YourLifeChoices cited the research. Nearly half of people got a shock.
They faced a lower refund, a tax bill, or contact from the ATO. Six in 10 doubted their return after they lodged it.
A late return can also delay a tax refund. The ATO cannot finalise your refund until your return is in. So late lodgement can cost you time as well as money.
The ATO also links non-lodgement to the shadow economy. It estimates that the shadow economy costs the community about $25 billion a year. Unlodged returns can hide income that never enters the system.
What to do now
Check your pre-filled data first. Compare each line with your own records. Look at your payslip and income statement, bank interest, and super.
Do not trust pre-filled figures alone.
Follow the ATO's three rules for deductions. You paid the cost. It relates to earning income.
You have proof. If one rule fails, do not claim the cost.
Lodge now, even if you cannot pay. You can ask for a payment plan later. Lodging stops the 28-day clock.
Waiting only grows the fine.
If you need more time, join a tax agent before 31 October. Ask the agent for their lodgement date. Get on their books in time, or the extra time will not apply.
If you missed an old return, catch up. The myTax system supports returns from 2016 onward, according to Kalkine. Old returns will not fix themselves.
If you had no income, file a non-lodgement advice. That tells the ATO you did not need to lodge. It takes a few minutes, and it closes the loop.
The deadline is two weeks away. Two million people still need to file. A short check now can save a fine later.
Lodge on time, or get on an agent's books before 31 October.
