Deadlines can shift slightly if a date falls on a weekend or holiday, or if IRS disaster relief applies to your area, we'll confirm anything specific to your return. An extension moves your filing deadline, not your payment deadline: any tax owed is still due by the original April date.

Don't wait for the deadline rush.
