The Australian Taxation Office (ATO) generally has a 2-year amendment period for individuals with simple tax affairs and small business entities, starting from the date of the notice of assessment. For more complex affairs (e.g., trusts, companies, or higher-income individuals), this period is typically 4 years. However, the ATO can go back indefinitely in cases of fraud or tax evasion.

For most people, keeping records for 3-7 years covers standard audits, but if those returns are from a time you bought/sold property or have complex investments (like worthless securities), you might need them longer, so consider shredding or securely disposing of anything older than 7 years unless it's for property records.
