The federal tax filing deadline for the 2025 tax year (returns filed in 2026) is April 15, 2026 for most individual taxpayers in the United States.

Quick Scoop

  • For most individuals, your 2025 Form 1040 is due April 15, 2026.
  • This date is also the deadline to pay any tax owed and to file an extension request.
  • If you file a valid extension (Form 4868), you can typically extend your filing deadline to around October 15, 2026 , but you still must pay by April 15 to avoid interest and some penalties.
  • Some taxpayers living outside the U.S. may get an automatic extra two months to file, but the tax is still generally due by April 15.

Mini FAQ

Does the deadline ever move?
If April 15 falls on a weekend or federal holiday, the deadline may shift to the next business day; for 2026 it remains April 15 under current published calendars.

Is this the same as business deadlines?
No, businesses (like S-corps, partnerships, and corporations) have their own key dates, often in March and September, which are different from the individual April 15 date.

Always check the IRS website or a tax professional close to filing season in case of special relief (for example, natural disasters) that can change deadlines for certain areas.

TL;DR: The answer to “when is the tax deadline for 2025?” for U.S. individual federal income taxes is April 15, 2026 , with a possible extension to about October 15, 2026 for filing (but not for paying).
