Every year, the Australian Taxation Office (ATO) sets strict deadlines for lodging tax returns. Missing these deadlines can result in penalties and interest charges. Here’s everything you need to know about the 2025 tax return deadline in Australia.
1. Standard Lodgment Deadline
For most individuals lodging their own tax return (without an agent), the deadline is:
31 October 2026
This applies if you use the myTax system via MyGov or submit a paper return.
2. Using a Registered Tax Agent
If you use a registered tax agent like TaxVisory, you may be eligible for extended lodgment dates beyond 31 October. To qualify, you must:
- Be registered with your tax agent before 31 October.
- Provide your documents and information on time for them to lodge on your behalf.
3. Business Activity Statement (BAS) Deadlines
If you’re running a business, you may also need to lodge Business Activity Statements (BAS) quarterly. For the July–September quarter, the BAS is due by 28 October 2026.
4. Penalties for Missing Deadlines
The ATO can issue a Failure to Lodge (FTL) penalty, starting at $313 and increasing every 28 days you are late, up to a maximum of $1,565 for small businesses.
Late lodgment may also delay your refund and attract extra scrutiny from the ATO.
5. Tips to Stay Ahead
- Gather your documents early (income statements, receipts, deductions).
- Use a tax agent if you’re not confident in lodging yourself.
- Don’t wait until the last week of October—ATO systems can get overloaded.
