If you use the services of a registered agent to prepare your income tax return or other required forms, your agent will advise you when these are to be lodged. Contact your agent to establish when they require your information to lodge your return and forms on time. You remain responsible for ensuring that the necessary information is with your agent in time.
If you don't have a registered agent, you should lodge according to the dates listed in this document. If you cannot lodge by that date, phone 13 28 66 as soon as possible (before the date which is shown on the form) to find out if you can lodge at a later date.
Where a due date falls on a day that is not a business day (that is, the due date is a Saturday, a Sunday or a public holiday), lodgment or payment may be made on the first business day after the due date without incurring a penalty or general interest charge.
A business day means a day other than a Saturday or a Sunday, or a day that is a public holiday. A public holiday is a day that is a public holiday for the whole of any state or territory in Australia.
Lodgment and/or payment will be due on the next business day for all taxpayers regardless of where the taxpayer is located.
If the due date falls on a public holiday which is a public holiday for the whole of a state or territory, taxpayers in all states and territories may lodge and/or pay on the first business day regardless of whether they celebrate that public holiday in their own state or territory.
