Tax rulings

If you have a tax-related question specific to your business, you may request more specific help. You can email the department at rulings@dor.wa.gov and we will send you a binding tax ruling, which is a letter that describes your tax obligation in greater detail. You must include the business name and other business details you find important. Tax rulings are binding on both the taxpayer and the Department of Revenue.
