Legislative resources
The Department of Revenue provides nonpartisan tax assistance to executive and legislative entities. We are committed to delivering clear, objective recommendations and analysis to inform statewide tax policies. Please explore our comprehensive reports and tailored legislative resources below.
The work of the legislative liaisons includes:
- Assisting legislative offices with constituent casework.
- Monitoring and reviewing state legislation.
- Providing fiscal notes and estimates.
- Assisting in drafting bill language and technical reviews of amendments.
- Proposing agency request legislation that improves how DOR administers tax laws and public service programs.
The Department of Revenue is the state’s primary tax agency. We collect and administer 93% of tax revenue for the state and oversee about 60 categories of taxes that help fund education, social services, health care, public safety, natural resource conservation and other services counted on by Washington residents. Our mission is to efficiently administer tax laws and public service programs with integrity. The department does this by providing tax education to individuals and businesses, processing business license applications. The department also administers programs such as the Working Families Tax Credit and Unclaimed Property.

DOR develops agency request legislation that improves the administration of the state’s tax code and ensures a positive and fair environment for businesses and taxpayers. If approved by the governor’s office, DOR may seek to have agency request legislation introduced by a lawmaker on the department’s behalf.
