For U.S. federal income taxes for the 2025 tax year (filed in 2026), most individual tax returns are due on or around April 15, 2026 , unless that date is moved because of a weekend, holiday, or special IRS announcement.

Core due dates (U.S., 2026)

  • Individual Form 1040 return: Generally April 15, 2026, for calendar‑year taxpayers.
  • Extension for individuals: If you file an extension (Form 4868), you typically get until mid‑October 2026 to file, but any tax owed is still due by the April deadline.
  • First 2026 estimated tax payment: Usually also due on the April filing deadline (the same mid‑April date in 2026).
  • Employer wage forms (what you need to file accurately):
    • W‑2s must be sent to employees by January 31, 2026.
* Most 1099 forms are due to recipients by January 31 or mid‑February 2026, depending on the type.

Business and other entity deadlines (U.S., 2026)

  • Calendar‑year C corporations (Form 1120): Due April 15, 2026; extension usually adds six months.
  • Calendar‑year exempt organizations (Form 990 series): Typically due May 15, 2026, with a possible six‑month extension.

Important note

  • Exact dates can shift slightly if April 15 falls on a weekend or legal holiday, or if the IRS grants broad extensions (for example, after major disasters).
  • State and non‑U.S. deadlines can be different. For example, India’s ITR due date for many individuals for FY 2025–26 is July 31, 2026, not April 15.
