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

The last day to send in federal income tax forms is April 15. This date is significant because it marks the deadline for individual taxpayers to file their annual income tax returns with the Internal Revenue Service (IRS). Taxpayers are typically expected to report their income and any tax liabilities for the previous calendar year by this date. If April 15 falls on a weekend or a holiday, the deadline may extend to the next business day, but under normal circumstances, April 15 is the crucial date. This timeline for tax filing is part of the annual financial obligations of U.S. citizens and residents, ensuring that everyone pays their fair share of taxes by the established deadline.
