For most individual taxpayers the tax filing and payment deadline is Monday, April 18, 2022. Those who need more time to file can request an extension to file. Taxpayers must request an extension to file by April 18, or they may face a failure to file penalty. This extension gives them until October 17 to file their tax return. An extension to file is not an extension to pay.

Most taxpayers must pay taxes by April 18 to avoid penalties and interest on the amount owed after that date. Taxpayers in Maine and Massachusetts have until April 19 to pay to file their returns due to the Patriots’ Day holiday in those states.
