The deadline to amend a tax return, if you need to amend a tax return, it must be filed by the later of:
- three years from the original due date of the return,
- three years from the date you actually file if after the deadline or
- within two years of paying tax for that year.
For a 2020 tax return filed in 2021, the deadline was automatically extended to May 15, 2021 and therefore 2021 amended returns have to be filed prior to May 15, 2024.
