There are time limits for amending your tax returns. For most people, the time limit for amending your tax returns is two years from the day we issue your notice of assessment for that year. For some people, the period is four years.
If the time limit for amending your tax return has passed, you may still be able to have your request to make a later election considered but you will need to lodge an objection against your assessment for the relevant year. You will need to request an extension of time when you lodge your objection.
