The last day to file federal income tax forms for the 2025 tax year is April 15, 2026. This applies to most individual filers submitting Form 1040, with payments due the same day even if you get an extension.

Standard Deadline Details

April 15 marks the standard cutoff since it doesn't fall on a weekend or holiday in 2026. Postmarking your mailed return by this date counts as on-time filing. E-filers must submit by midnight.

If you're due a refund, filing early speeds up processing—IRS opened the 2026 filing season on January 26. Owe taxes? Pay by April 15 to dodge failure-to- pay penalties up to 0.5% monthly.

Extensions and Exceptions

  • Automatic 6-month extension: File Form 4868 by April 15 for an October 15, 2026 deadline—but pay any owed taxes upfront.
  • Disaster relief: Check IRS.gov for possible shifts if your area qualifies.
  • Fiscal year filers: Due 15th day of the 4th month after year-end.
