When is the deadline to submit federal income tax forms?

The deadline to submit federal income tax forms is typically April 15th. This date is set by the Internal Revenue Service (IRS) and is the standard deadline for individuals to file their annual tax returns for the previous calendar year. If April 15th falls on a weekend or a holiday, the deadline may be extended to the next business day, but under normal circumstances, taxpayers should aim to have their forms submitted by this date.

Other dates listed do not align with the federal tax submission timeline. For instance, March 15th is significant for certain business entities and partnerships that operate on a calendar year, but it is not the deadline for individual tax returns. April 1st and May 1st also do not represent any commonly recognized deadlines for federal income tax submissions, making April 15th the accurate point of reference for individual taxpayers.
