When Are Tax Returns Due in Australia? (Quick Scoop)

Key dates at a glance

For the 2024–25 income year (1 July 2024 – 30 June 2025):

• Self‑lodged individual returns (myGov/ATO online or paper):
  • Due 31 October 2025.

• Using a registered tax agent :
  • You can often lodge later, commonly up to 15 May 2026 , if you are on the agent’s lodgment program and usually signed up by 31 October.

If you miss 31 October and are not on a tax agent’s list, the ATO can apply late‑lodgment penalties, which increase the longer you delay.

Self‑lodged vs tax‑agent deadlines

Self‑lodged (DIY)

• Most individual taxpayers: deadline 31 October after the end of the tax year.

• This applies whether you’re an employee, sole trader, or freelancer, as long as you lodge yourself.

Via a registered tax agent

If you use a registered tax agent and they add you to their ATO client list in time:

• Many individuals and small trusts get until 15 May of the following calendar year to lodge (for 2024–25, that’s 15 May 2026).

• Some with large prior‑year tax bills or large/medium trusts have earlier staggered dates (for example 31 March 2026 or 28 February 2026 , depending on circumstances).

Example: How it works in practice

Imagine you worked in Australia from 1 July 2024 to 30 June 2025:

• If you lodge your tax return yourself through myGov:
  • You must lodge by 31 October 2025.

• If you sign up with a tax agent by 31 October 2025:
  • You’ll likely have until 15 May 2026 to lodge, unless you fall into a special earlier‑deadline category (like having a large prior‑year tax liability).

Other important ATO lodgment dates (high level)

These won’t apply to everyone but are part of the broader “when are tax returns due Australia” picture:

• 28 February 2026 – Some large and medium non‑taxable trusts and new registrant trusts.

• 31 March 2026 – Individuals and trusts whose last return showed a tax liability of 20,000 AUD or more (excluding large/medium trusts).

• 15 May 2026 – Remaining individuals and trusts on an agent’s program, not required earlier.

Mini FAQ (forum‑style)

Q: Is 31 October always the deadline in Australia?
For most individual self‑lodgers, yes: 31 October after the end of the tax year is the standard deadline.

Q: Can I get more time automatically?
Usually only if you are on a registered tax agent’s lodgment list; then your due date is determined by the ATO’s agent program (often up to 15 May).

Q: What if I’m late?
The ATO can charge a “failure to lodge on time” penalty, which grows with each 28‑day period you remain late, up to a maximum amount.
