On March 17, 2021, The Treasury Department and Internal Revenue Service announced today that the federal income tax filing due date for individuals for the 2020 tax year will be automatically extended from April 15, 2021, to May 17, 2021. The IRS will be providing formal guidance in the coming days.

State Tax Returns

The federal tax filing deadline postponement to May 17, 2021, only applies to individual federal income returns and tax (including a tax on self-employment income) payments otherwise due April 15, 2021, not state tax payments or deposits or payments of any other type of federal tax. Taxpayers also will need to file income tax returns in 42 states plus the District of Columbia. State filing and payment deadlines vary and are not always the same as the federal filing deadline.
