For U.S. federal income taxes for the 2025 tax year (filed in 2026), Tax Day is Wednesday, April 15, 2026.

Key 2026 tax deadlines (U.S.)

  • April 15, 2026 – Regular deadline to file your 2025 individual federal return (Form 1040) and pay any tax due.
  • April 15, 2026 – First-quarter 2026 estimated tax payment due if you make quarterly payments.
  • June 15, 2026 – Second-quarter 2026 estimated tax payment due.

Quick notes and “what ifs”

  • If you file an extension: You must still pay your estimated 2025 tax by April 15, 2026; the extension only gives you more time to file paperwork, not to pay.
  • If you live in a federally declared disaster area: The IRS may postpone your due date, so check the latest relief notices on IRS.gov.
  • State taxes: Many states follow the federal April 15 date, but some have different deadlines—check your state’s revenue or tax agency site.

If you tell me your country or state, I can help narrow down the exact tax due date rules for your situation.

TL;DR: For most U.S. individuals, your 2025 taxes are due April 15, 2026; if you extend, you have until October 15, 2026, but payments are still due in April.
