June 30, 2021

Extended deadline for filing and furnishing the Form 5498 series.


HEADS UP: No extension is provided for the filing of any other return other than the Form 1040 series and the Form 5498 series for the 2020 taxable year


On March 29, 2021, the Internal Revenue Service issued Notice 2021-21, which extends tax deadlines for filing Form 1040 series returns and other deadlines to May 17, 2021. The Notice, issued as a result of the ongoing COVID-19 pandemic, follows a prior IRS extension (also to May 17, 2021) of the federal income tax filing due date for individuals for the 2020 tax year.

The Form 1040 series includes Form 1040, Form 1040-SR, Form 1040-NR, Form 1040-PR, and Form 1040-SS. Businesses and other types of taxpayers that file federal income tax returns on forms outside of the Form 1040 series are not eligible for the extension. In addition, the Notice does not alter the April 15, 2021 deadline for estimated tax payments.


Contributions to IRAs and Other Accounts

  • Individuals will now have until May 17, 2021 to make 2020 contributions to their IRAs and Roth IRAs, HSAs, Archer medical savings accounts, and Coverdell education savings accounts.
  • Due date for Form 5498 series returns has been postponed to June 30, 2021. The period beginning on the original due date of those forms and ending June 30, 2021, will be disregarded in calculating any penalty for failure to file.

Other Extended Deadlines

The Notice also extends, to May 17, 2021, the time to claim refunds for 2017 federal income tax returns and the time to file an application to voluntarily participate in the Annual Filing Season Program for calendar year 2021.
