For the 2026 tax season in the United States, the federal tax filing deadline for individual 2025 returns is Wednesday, April 15, 2026.

Core date you need

  • Tax Day 2026 (individuals, Form 1040): April 15, 2026. This is the last day to file your 2025 federal income tax return and pay any remaining tax without late-filing and late-payment penalties, unless you qualify for special relief (for example, certain disaster areas).
  • The IRS is opening the 2026 filing season on January 26, 2026, which is when it starts accepting and processing 2025 returns.

Extensions and other key deadlines

  • You can request an automatic extension to file (typically via Form 4868) by April 15, 2026 ; this usually moves your filing deadline to October 15, 2026 , but any tax you owe is still due April 15.
  • For many entities (trusts and C‑corps) the regular filing deadline is also April 15, 2026, and extended returns are generally due October 15, 2026.
