Mini FAQ

What if April 15 is a weekend or holiday?

In years when April 15 falls on a weekend or legal holiday, the deadline typically moves to the next business day. For 2026, April 15 is a Wednesday, so the standard date applies.

What if I file an extension?

  • You can request an automatic extension to file until October 15, 2026.
  • The extension only gives you more time to file , not to pay ; unpaid balances after April 15 can incur interest and penalties.
