If you realize you didn’t claim the correct filing status, or entered incorrect income, deductions, or tax credits, you can file an amended return up to three years after the date you filed the original return — or within two years of paying the taxes owed, whichever is later.

Since the deadline to file your 2021 taxes this year is April 18, 2022, you have until April 18, 2025 to file an amended return if you realize you made an error. You can file amended returns for taxes filed in 2019 or later this year.
