You must file an amended tax return entering the corrected info and an explanation of why are you changing your report. Based on the three-year rule, you can file an amended tax return during the next three tax seasons. But it depends on what type of mistake you’ve found.
For example, if the correction states that you owe more taxes, it makes sense to file the amendment ASAP.
The IRS charges penalties and interest after the tax deadline.
