The deadline for filing the 2020 federal income tax return in the United States was automatically extended from April 15, 2021, to May 17, 2021. Taxpayers who needed more time after that could request an extension to file until October 15, 2021, but tax payments were due by May 17, 2021, to avoid penalties and interest.
Additionally, for claiming 2020 tax refunds, the IRS reminded taxpayers that the deadline to file 2020 returns and claim refunds was May 17, 2024, as the three-year window for claiming refunds was extended due to the pandemic.
