For the 2025 tax year (the return you file in 2026), federal Tax Day in the U.S. is Wednesday, April 15, 2026 for most individual filers.

Quick Scoop: What Day Are Taxes Due?

  • Standard deadline to file your 2025 federal individual income tax return (Form 1040) :
    April 15, 2026.
  • If you file an extension (Form 4868) , you can delay filing the paperwork until October 15, 2026 , but you still must pay any tax owed by April 15 to avoid interest and late-payment penalties.
  • If April 15 ever falls on a weekend or federal holiday , the deadline usually shifts to the next business day (not the case in 2026, since April 15 is a Wednesday).

Simple example

If you work a regular W‑2 job in 2025 and don’t request an extension, you should plan to file and pay any remaining 2025 federal taxes by April 15, 2026.

If you request an extension, you could send in your full return as late as October 15, 2026 , but any unpaid balance from 2025 would start racking up interest after April 15.
