Amending an Australian Tax Return — Complete Resource
Lodged something wrong? You have 2 years from your Notice of Assessment to fix it via myTax.
Realising you missed a deduction or under-reported income after lodging is more common than you'd think — and the ATO actually wants you to self-correct. You have 2 years from your Notice of Assessment date to amend through myTax, and 4 years for some specific items. Self-amendments rarely attract penalties; the ATO charges only General Interest Charge (GIC) on any additional tax owed, calculated from the original due date. This hub covers the amendment process, when to use a formal Objection instead, and the most common situations where amendments make sense.
