    'Relevant period' label from Company tax return 2010

    An entity's income year for the purposes of tax law is usually the period of 12 months ending on 30 June each year.

    If you do not write any dates in this field, then your organisation will be treated as having a 1 July to 30 June income year.

    Common errors: dates shown incorrectly

    There are two main errors:

    • writing a period other than ending 30 June, without having an approved substituted accounting period (SAP)
    • having an approved SAP, but not writing any dates.

    Consequence of these errors

    We may return your tax return as incomplete and ask you to lodge it with the approved SAP balance date, that is, the date on which your income year ends. We will consider that you have not lodged a tax return until you lodge your corrected tax return.

    We may approve a SAP retrospectively, but this can result in:

    • pay as you go instalments incorrectly allocated to a wrong year
    • incorrect lodgment due dates
    • delays in the processing of refunds
    • possible application of penalties in appropriate circumstances.



    An entity that wishes to adopt a SAP can only do so by obtaining leave of the Commissioner of Taxation.

    End of attention

    An entity with an approved SAP should use the company tax return for the correct income year. For example, if an organisation has an approved SAP with a balance date between:

    • 1 July 2009 and 30 November 2009 inclusive, it should use the 2009 company tax return
    • 1 December 2009 and 30 June 2010 inclusive, it should use the 2010 company tax return.

    How do you know whether your organisation has an approved SAP?

    We would have sent you a letter confirming your approved SAP.

    You can also check whether your organisation has an approved SAP by phoning us on 1300 130 248.

    Do your organisation's circumstances warrant the granting of a SAP?

    A SAP may be approved if your organisation can demonstrate that its circumstances are out of the 'ordinary run'.

    Circumstances which are out of the 'ordinary run' include:

    • an ongoing event, industry practice, business driver or other ongoing circumstance which makes 30 June either inappropriate or impractical as a balance date
    • alignment of balance dates within a group.

    While it is not possible to set out all the circumstances in which a SAP may be granted, Law Administration Practice Statement PS LA 2007/21 - Substituted accounting periods contains examples of facts and circumstances that may be considered relevant in deciding if a SAP should be granted.
