  • Due dates for lodging and paying

    Keep up with key dates for small businesses

    Our due dates by month and due dates by topic give you key dates to help you lodge and pay on time.

    Due date falling on a weekend or public holiday

    When a due date falls on a Saturday, Sunday or public holiday, you can lodge or pay on the first business day after without incurring a penalty or general interest charge.

    Substituted accounting periods

    The income tax due dates are for entities that balance on 30 June – that is, at the end of the Australian financial year. They don't apply to entities that use a substituted accounting period.

    If you need more time to lodge

    If you prepare and lodge your own return and need additional time, phone us before the due date on 13 28 66 during available hours.
