• Assessments and amendment periods

    The standard period in which we can amend an assessment is four years for most businesses in privately owned and wealthy groups. There is no time limit if we find fraud or evasion.

    We will work with you to clarify these timeframes when we engage with you, to limit potential uncertainty.

    This information may not apply to the current year. Check the content carefully to ensure it is applicable to your circumstances.

    End of attention

    Different rules relating to the amendment period can apply to some cases where transfer pricing, research and development and capital gains tax is involved.

    Generally, you will have the opportunity to present your case before we issue an amended assessment.

    Indirect taxes – GST, wine equalisation tax, fuel tax credits and luxury car tax

    If we make an adjustment to your activity statement as a result of compliance activity we have undertaken (whether to increase or decrease your liability), we will do it by making an amendment to your assessment and issue a notice of amended assessment. For tax periods commencing before 1 July 2012 this will usually be an assessment.

    Generally under our processes we need to provide you with details and reasons for any adjustment before we issue an amended assessment. You will have the opportunity to raise any concerns before the amended assessment is made.

    Excise (fuel, alcohol and tobacco)

    If we identify an adjustment to your excise liability, we will work with you to amend the appropriate excise return.

    Should you disagree with an identified adjustment in excise liability, generally you will be given every reasonable opportunity to present your case before we issue a demand for the amount of excise duty.

    The cleaner fuels grants scheme closed on 1 July 2015. For more information on outstanding claims and requesting amendments visit ato.gov.au
