Getting Ready to Lodge Your 2026 Tax Return

After 30 June, your priority should be gathering documentation to lodge or provide to your accountant.

Have ready: investment income summaries, rental property statements, CGT records, and all receipts for deductions.

Frequently Asked Questions

What is the tax return deadline for 2026?

The individual income tax return for the 2025-26 year is due by 31 October 2026 for self-lodgers. If you engage a registered tax agent before this date, you may have until 15 May 2027. Businesses have different lodgement dates based on their entity type and tax agent relationship.

Can I still contribute to super after 30 June for a 2026 deduction?

No. Concessional super contributions must be received by your fund by 30 June 2026 to be deductible in the 2025-26 year. Contributions made on or after 1 July 2026 apply to the 2026-27 year. Initiate transfers early — bank transfers to super can take 1-3 business days.
