WASHINGTON -- Here's a look at the annual income tax filing deadline in the United States.

April 18, 2022, is the deadline to file 2021 income tax returns.

Why is it not April 15?

The IRS says: "By law, Washington, D.C., holidays impact tax deadlines for everyone in the same way federal holidays do. The due date is April 18, instead of April 15, because of the Emancipation Day holiday in the District of Columbia for everyone except taxpayers who live in Maine or Massachusetts. Taxpayers in Maine or Massachusetts have until April 19, 2022, to file their returns due to the Patriots' Day holiday in those states. Taxpayers requesting an extension will have until Monday, October 17, 2022, to file."
