The countdown is on! The 31st October 2025 tax deadline is just around the corner, and if you haven’t lodged your tax return yet, it’s time to act fast.
Missing the deadline matters. The ATO can apply Failure to Lodge (FTL) penalties that start at one penalty unit (currently $330) and increase every 28 days, up to a maximum.
The key is simple: stay organised, know the rules, and get help from a trusted Melbourne tax accountant before the ATO clock runs out.
Here’s everything you need to know to stay compliant, stress-free, and on track this tax season.
Why 31 October Tax Deadline Matters?
Each year, the Australian Taxation Office (ATO) sets 31 October as the due date for individuals lodging their own tax returns. If you’re handling your own return, this deadline applies directly to you.
However, if you plan to use a Melbourne tax accountant, you may qualify for extra time, but only if your accountant has you registered with the ATO by 31 October. Missing that enrolment date means you must still lodge by the standard deadline.
If you miss it, here’s what could happen:
- Late lodgement penalties (starting from hundreds of dollars)
- Interest on unpaid tax
- Delays in processing refunds
So don’t wait, 31 October is closer than you think.
Why hire a Melbourne tax accountant now?
Working with a local Melbourne tax accountant or business advisor brings immediate benefits at this time of year:
- They can identify overlooked deductions for small business owners and sole traders that reduce taxable income.
- They understand Victorian business rules, payroll nuances, and how to treat capital gains for property sales.
- Registered agents can provide lodgment program extensions only if you’re onboarded on time.
If you’re weighing options, look for accountants who advertise clear services like Business Tax Returns, BAS lodgment Melbourne, and integrated bookkeeping services that combine to reduce last-minute surprises and make the 31 October rush manageable.
What Happens If You Miss the Tax Return Deadline?
Life happens, maybe you were travelling overseas, going through an illness, or just lost track of time. Whatever the reason, missing the ATO deadline can lead to late lodgement penalties.
ATO Late Lodgement Penalties
If your return isn’t lodged by 31 October, the ATO may issue a Failure to Lodge (FTL) penalty.
Here’s how it works:
- $330 fine for every 28 days (or part thereof) that your return is overdue
- Maximum penalty of $1,650 for individuals and small entities
- Higher penalties may apply for medium and large entities
These penalties can add up quickly, especially if you delay for several months. The ATO can also apply general interest charges (GIC) on any unpaid tax, compounding daily until you settle your balance.
How to Fix a Late Tax Return
If you’ve missed the 31 October 2025 tax deadline, don’t panic. The most important thing is to act quickly. Here’s what to do next:
1. Lodge as Soon as Possible
Even if the deadline has passed, lodging promptly reduces your potential penalties. The longer you wait, the higher the fine.
2. Contact the ATO
Let the ATO know if you have a genuine reason for lodging late such as medical issues, family emergencies, or being overseas. You can request remission or reduction of penalties if you have supporting documents like a doctor’s certificate or travel records.
3. Seek Help from a Registered Tax Agent
If you’re unsure how to proceed or are missing documents, a registered tax agent can help retrieve income and deduction information from the ATO’s records. Agents can also ensure you claim every eligible deduction while keeping your return compliant.
4. Lodge Any Outstanding Returns
If you still have prior-year tax returns outstanding, it’s important to complete them before lodging your current year’s return. The ATO often blocks extended agent lodgement programs if you have older, unlodged returns.
BAS & lodgment timing — a quick note
If your business reports quarterly, key BAS lodgment dates sit around the end of October for the July–September quarter; monthly BAS is due on the 21st of the month following the reporting period. If your business qualifies for agent concessions, check with a BAS lodgment service or registered BAS agent.

Frequently Asked Questions
Is 31 October the deadline for using a tax agent?
You can get lodgment extensions if you use a registered tax agent — but you must be added to their client list by 31 October and have prior-year returns lodged. Check with your agent.
Can I still use a tax agent after 31 October?
Yes, but you won’t get the extended due dates unless you are registered with the agent before 31 October. The sooner you sign up, the better your chances of avoiding penalties.
What if I can’t pay my tax bill?
Lodge your return anyway, then contact the ATO to arrange a payment plan. The ATO often helps taxpayers who communicate early and are willing to pay.
