The last day to file your individual federal income taxes for the 2024 tax year is April 15, 2025. If you need more time, you can request an extension by filing Form 4868, which extends the filing deadline to October 15, 2025. However, any taxes owed must still be paid by April 15, 2025, to avoid interest and penalties. Extensions only apply to filing, not payment. For specific exceptions, such as for U.S. expats, the automatic extension to file is until June 15, 2025, with a further extension possible until October 15, 2025, if Form 4868 is filed on time. In some cases, certain areas affected by natural disasters may have even later filing deadlines. So, in summary:

• Regular filing deadline: April 15, 2025
• Expat automatic extension: June 15, 2025
• Extended filing deadline with Form 4868: October 15, 2025

Any taxes owed must be paid by April 15, 2025, regardless of any filing extensions to avoid penalties.
