Tax Day in the United States for the 2025 tax year (the return you file in 2026) is April 15, 2026.

Quick Scoop: When is “Tax Day”?

In the U.S., “Tax Day” is the deadline for most individual federal income tax returns to be filed with the IRS. Since the 1950s, that day is typically April 15 , unless it falls on a weekend or a holiday, in which case it shifts to the next business day.

For the current cycle:

  • Tax Day 2026 (for your 2025 income) is April 15, 2026.
  • That’s also the deadline to pay any tax you owe to avoid interest and most penalties, even if you file an extension.
  • If you request an extension, you generally have until October 15, 2026 to file , but you still must pay by April 15.

A Bit of Background

Historically, Tax Day has moved a few times:

  • The modern federal income tax began after the Sixteenth Amendment was ratified in 1913, which introduced the concept of a national income tax and a filing deadline.
  • Since 1955 , the standard deadline has been around April 15 , with occasional shifts due to weekends, Emancipation Day (D.C. holiday), or special circumstances.
  • When April 15 lands on a Friday or Saturday and aligns with Emancipation Day or Patriots’ Day, the due date can move to April 17 or 18.

Some useful waypoints around Tax Day 2026:

  • Late January–early February 2026 : Employers and many payers must send out W‑2s and key 1099s , typically by around Jan 31 / early Feb , so you can start filing accurately.
  • January 13–26, 2026 (approx.) : IRS begins accepting 2025 e‑filed returns in mid‑ to late January; exact dates like Jan 13 and Jan 26, 2026, are cited by major tax services.
  • April 15, 2026 :
    • Tax Day – deadline to file your 2025 federal return if you don’t extend.
* Deadline to **pay** any 2025 balance due to avoid extra charges.

* Deadline to file **Form 4868** to request an automatic extension to file.
  • October 15, 2026 : Deadline to file if you obtained an extension for your 2025 individual return.

Simple Example

Imagine you worked a regular job all through 2025.

  • You should receive your W‑2 by early February 2026.
  • You can file your 2025 tax return any time after the IRS opens e‑filing (mid‑ to late January 2026).
  • If you wait, the last day to get it in without an extension is April 15, 2026.

If you’re reading this and that date is close, it’s generally a good idea to file as early as you reasonably can rather than waiting until the final day.
