Individual Income Tax Return Due Date
October 31
Individual Income Tax Returns — FY 2024–25
If you’re lodging your own tax return for the year ending 30 June 2025 (without a tax agent), you must submit it by 31 October 2025.
To lodge, you’ll need income details (e.g. PAYG income, bank interest, dividends) and any relevant deductions.
Missing the deadline may result in penalties, plus interest if tax is payable. You can avoid this by lodging early or registering with a tax agent before 31 October to access extended deadlines.
