For the 2025 tax season in Australia, most individual tax returns (for the 2024–25 financial year) need to be lodged by 31 October 2025 if you lodge them yourself.

Key 2025 tax dates

  • The 2024–25 financial year runs from 1 July 2024 to 30 June 2025.
  • You can start lodging your tax return from 1 July 2025 via myTax, a tax agent, or paper.
  • The standard deadline for self-lodged individual returns is 31 October 2025.

If you use a tax agent

  • If you lodge through a registered tax agent and are on their client list by 31 October 2025, you may get an extension to around 15 May 2026, depending on your circumstances and their lodgement program.
  • These extended dates can also affect when your payment is actually due, with staggered payment deadlines into March–June 2026.

Late lodgement and penalties

  • Missing the 31 October 2025 deadline when you are required to lodge can lead to ATO failure-to-lodge penalties that increase the longer you delay.
  • Penalties are calculated in units and can quickly add up if you are several weeks or months overdue, especially if you have multiple outstanding years.

Forum / “latest news” style notes

  • Around October each year, Australian news outlets and forums tend to run reminders that “time is running out” for self-lodged returns as 31 October approaches.
  • For 2025, that same pattern applies: expect a lot of online discussion and reminders in October 2025 about the looming 31 October deadline for DIY lodgers.
