State of Washington Business Income Tax Extensions

E-file an IRS business tax extension with TaxExtension.com

General Instructions

The State of Washington does not impose an income tax. This means that Washington taxpayers do not need to request a state tax extension for filing a business tax return. If you received email confirmation from TaxExtension.com that your Federal tax extension was approved by the IRS, there is nothing else you have to do.
