Yes, you can.
You may need to amend your tax return if you have a mistake that needs to be corrected. This can include forgetting to include some income or forgetting to claim a deduction.
However, there are time limits within which you need to do this. Individuals, sole traders and small to medium businesses generally have two years to submit an amendment to their tax return. The time starts from the day after your notice of assessment is sent to you.
All other taxpayers have four years in which to submit an amendment.
Get in touch with our support team if you believe that an amendment is necessary and we will take care of this for you.
