When is the last day you can send in federal income tax forms?

The last day to file federal income tax forms is typically April 15. This date marks the deadline for individuals to submit their tax returns for the previous calendar year or to request an extension if they cannot meet the deadline. April 15 has been the longstanding date by which taxpayers must either file their taxes or ensure that their payment is postmarked if sending a check.

Filing your federal income tax return by this date helps avoid penalties and interest on any amounts owed. If April 15 falls on a weekend or a holiday, the deadline may be extended, but it is crucial to be aware of the standard deadline to ensure compliance with tax regulations.
