The last day to file your 2025 federal income taxes (the return you file in 2026) is Wednesday, April 15, 2026 for most individual taxpayers in the U.S.

Quick Scoop

  • Standard deadline (no extension): April 15, 2026.
  • If you file an extension: You can file your return as late as October 15, 2026 , but you still must pay any tax owed by April 15, 2026 to avoid penalties and interest.
  • IRS wording: Taxpayers have until April 15, 2026, to file 2025 tax returns and pay any tax due.

Short example

If you e-file an extension on April 10, 2026 and owe 2,000 in tax, you must still pay that 2,000 by April 15, 2026; the extension only moves your paperwork deadline to October 15, 2026.
