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

The last day to send in your federal income tax forms is April 15th. This date is established by the Internal Revenue Service (IRS) and applies to most individual taxpayers. If April 15 falls on a weekend or a holiday, the deadline may be extended to the next business day, but under normal circumstances, April 15 is the definitive deadline for filing annual tax returns. Meeting this deadline is crucial to avoid penalties and interest on any taxes owed. Understanding the significance of this date helps individuals stay compliant with tax regulations and avoid potential issues with the IRS.
