Tax and Population Data

This page contains data on city and county populations, assessed valuations, property tax levies, sales tax distributions, and sales tax components/rates in Washington State, compiled from information provided by the state Department of Revenue (DOR), Office of Financial Management (OFM), and Office of the State Treasurer (OST).

Have you used our tax and population data?

If so, we'd love to hear how you used it! Please take a minute to answer five brief survey questions.

Population, Property Tax, and Sales Tax Distribution Data

This data is updated several times per year as new data is provided by DOR, OFM, and OST. These files include the following information on a calendar year basis:

  • Population estimates – for counties, includes both unincorporated and total population.
  • Locally assessed values – for counties, includes both countywide (current expense) and unincorporated (road fund) assessed valuation.
  • Levy amounts, rates, and statutory maximum rates – you can filter this data by "levy type" to get information on different levies including current expense/general fund levies, EMS levies (RCW 84.52.069), road levy diversions, conservation futures levies (RCW 84.34.230), affordable housing levies (RCW 84.52.105), excess levies (RCW 84.52.052), and G.O. bond repayment levies (RCW 84.52.056).
  • Sales tax distributions for regular (also known as the "basic" or "first half") and optional ("second half") sales taxes – note that this only addresses unrestricted (general fund) sales tax revenues (dollar amounts) under RCW 82.14.030(1) and (2) and does not include additional restricted sales taxes that the jurisdiction may have imposed. However, we do provide the local sales tax percentage rates for each jurisdiction in the Local Sales Tax Rates & Components section below.

For more details on the various property tax levies and other local revenue options, refer to MRSC's City Revenue Guide and County Revenue Guide.

Please note: There is rarely an "apples to apples" comparison between jurisdictions. For instance, some cities provide their own fire and library services. Other cities are annexed to fire districts and/or library districts, which shifts some taxing authority from the city to the fire/library district. This can result in a significantly lower levy rate for the city, even though the total tax burden on property owners might be similar.

Likewise, some jurisdictions have imposed emergency medical services (EMS) levies, while many others are precluded from doing so due to EMS levies imposed by other taxing jurisdictions (such as fire districts, EMS districts, counties, and public hospital districts).

Some cities and counties have rapidly increasing property values, which can result in steadily decreasing levy rates due to the 1% levy limit (unless the jurisdiction submits a levy lid lift to voters), while other jurisdictions have relatively stable or even decreasing property values.

Local Sales Tax Rates & Components

Below is a current breakdown of the sales tax rates and components for each city, town, and county in Washington. This includes the 6.5% state sales tax rate, as well as the many voted and non-voted sales taxes applied by cities, counties, public facilities districts, and transit districts.

For more details on these various local sales tax options, see our page Sales and Use Taxes in Washington State or refer to MRSC's City Revenue Guide and County Revenue Guide.

Tax Reliance Map for Cities

Some cities rely more heavily on sales taxes, while others rely more on property taxes. See MRSC's tax reliance map to explore how your city's sales and property tax revenues compare to other jurisdictions across the state.
