when is tax filing deadline

The tax filing deadline for individual federal income tax returns in the United States for the 2024 tax year is April 15, 2025. If an extension is needed, taxpayers can file Form 4868 to extend the deadline to October 15, 2025. This extension must be requested by the original April 15 deadline. For those who need even more time, a further extension to December 15, 2025, may be available, especially for U.S. expats under certain conditions.
