What is the final date for sending in federal income tax forms?

The final date for sending in federal income tax forms is April 15. This date is significant because it marks the deadline set by the Internal Revenue Service (IRS) for individuals to file their federal income tax returns for the previous year. April 15 is chosen to provide taxpayers with the necessary time following the end of the tax year, which concludes on December 31.

In situations where this date falls on a weekend or a holiday, the deadline may be extended to the next business day, but typically, taxpayers can expect to submit their returns by April 15 each year. The importance of this date is underscored by its common recognition among taxpayers in the United States, often referred to as "Tax Day." Understanding this deadline is crucial for individuals to avoid penalties and ensure compliance with tax laws.
