As can be seen, on a countywide basis, charges for services make up the largest source of revenues for King County. These include revenues the county receives from providing services like wastewater treatment, solid waste disposal, airport facilities and transit. The next two categories are property and sales taxes which together make up over 40% of countywide revenues. These include all property tax levies in the county levy including the non-voted regular levy, the levy lid lifts and levies for transportation, marine, conservation futures, bond redemption, emergency medical services and the roads levy. Sales taxes are made up of the local option sales tax, the metro transit sales tax and those for mental health and criminal justice. Grants make up approximately 9.9% of revenues and include both capital and operating grants, Miscellaneous other taxes and interest revenue make up the remainder of county revenues.

Figure 1 indicates revenues for the county as a whole but King County also accounts for the goods and services it provides in two different sub-classifications; governmental activities and business activities. These sub-classifications are important since they highlight a very different revenue structure depending on the type of service.

Government activities are those that are recognized as basic government services like policing, courts, elections, and human services. Figure 2 indicates the revenue composition for King County’s governmental activities.

Service charges are the second largest source of revenues at 37.4%. If taxes are aggregated, they make up a largest share (47.5%) of general government revenues. Capital and operating grants make up about 11.7% of general government funding and interest payments represent about 0.6%.

Figure 3 indicates revenues for business type activities. As mentioned, business-type activities are those intended to recover all or a significant portion of their costs through user fees and charges to external users of goods and services. Included are the operation of the County’s public transportation system, wastewater treatment facilities, solid waste disposal, airport and other services. Also included is the operation of the King County Marine District.

As can be seen from Figure 3, 59.6% of revenues for business-type activities come from service charges and 30.4% from sales taxes. This sales tax revenue is the 0.9% tax levied countywide in support of metro transit. Transit also receives a small amount of property taxes which makes up about 1.5% overall. The remaining revenues are grants which total about 7.9%.
