SELF-ASSESSMENT & PERIODS OF REVIEW
Our taxation system works by a process of self-assessment. In broad terms, this means that the ATO will generally accept the contents of a tax return and process it and issue and assessment without any alterations to the information submitted. However, the ATO can legally require you to provide the information and records used to prepare a return. Your return may be selected by the ATO for a review or an audit.
Where tax has been underpaid the ATO may amend a return if they do so within the amendment period, known as the “period of review”. The period of review is the timeframe within which the ATO has the power to amend a tax assessment and a taxpayer can request and amendment or object to a tax assessment.
The period of review for small business entity taxpayers and most individuals is 2 years from the date of issue (or deemed date of issue) of the relevant Notice of Assessment.
The period of review is 4 years from the date of issue (or deemed date of issue) of the relevant Notice of Assessment for:
- non-small business entity taxpayers;
- nil income and loss taxpayers;
- individuals receiving distributions from non-small business entity trusts or partnerships (other than public trading trusts and corporate unit trusts).
In cases where tax fraud or evasion is considered to exist the period of review is unlimited.
