Planned system outage - 12 September 2026 | Our online services including myIR, self service phone lines and gateway services will be unavailable on Saturday 12 September, 2026 from 1pm to approximately 10.30pm while we complete a planned system update. We apologise for any inconvenience this may cause.

We’ve noticed that some tax agents have not linked themselves or their associated entities to their client list.

To receive an extension of time, you must be linked to the tax agency.

Income tax returns must be filed by 7 July if no extension of time is granted.

If a return has not been filed by the due date, late filing penalties will apply.

Please review your tax agency list to ensure eligible returns receive the correct extension of time. This will help to avoid unnecessary penalties.
