The deadline to file taxes for the 2024 tax year in the United States is April 15, 2025. If you need more time, you can file Form 4868 to request an extension, which extends the filing deadline to October 15, 2025. This extension applies to filing only; any taxes owed must still be paid by April 15 to avoid interest. There are further special extension deadlines under specific circumstances, but the standard deadline to file without extension is April 15, 2025.
