Washington State Individual Tax Extension Filing Instructions

The State of Washington does not have a state income tax. Therefore, individuals in Washington are not required to request a Washington personal income tax extension.

Even though the State of Washington does not require a personal income tax extension, the IRS still requires you to file Form 4868 by the regular due date of the return to get an additional 6-month automatic extension to file your 1040 personal income tax return.

For additional information, including other taxes that may apply to you, please visit the Washington State Comptroller's website
