The general federal deadline to file your 2025 U.S. individual income tax return (the return you file in 2026) is April 15, 2026.

If you file an extension, you’ll typically have until October 15, 2026 to file, but any taxes you owe are still due by April 15, 2026 to avoid interest and penalties.

Always double‑check the IRS site or a tax professional in case the date is adjusted for weekends, holidays, or special disaster‑area relief in your area.
