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

April 15 is the standard deadline for filing federal income tax forms in the United States. This date typically marks the end of the tax season for individuals, meaning that all individual income tax returns must be postmarked by this date or filed electronically by the same deadline.

In years where April 15 falls on a weekend or holiday, the deadline might be adjusted to the next business day; however, April 15 remains the general rule for most years. The other dates mentioned are not relevant for the federal income tax deadline. For instance, March 15 is typically the deadline for certain business tax returns, and April 1 and May 1 do not correspond to significant tax deadlines for individual income tax filings. Understanding this context is essential for managing tax obligations accurately and timely.
