The deadline to file individual federal income tax returns in the United States for the 2024 tax year (filed in 2025) is April 15, 2025. If April 15 falls on a weekend or holiday, the deadline shifts to the next business day. Taxpayers can request an extension to file until October 15, 2025, by filing Form 4868 before the April deadline. However, any taxes owed must still be paid by April 15 to avoid penalties and interest. Key deadlines for the 2024 tax year in the US:

• April 15, 2025: Regular tax filing deadline and payment due date.
• October 15, 2025: Extended filing deadline if Form 4868 is filed by April 15.
• December 15, 2025: Final extension deadline for special circumstances.

For expats, there is an automatic extension until June 15, 2025, and they can also file Form 4868 for an October 15 extension. In Canada, the deadline to file taxes for the 2024 tax year is April 30, 2025, with an extended deadline of June 15, 2025, for self-employed individuals (payment due by April 30).
