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).

New in January 2018: Sales Tax Rates & Components

Based on DOR data, MRSC has compiled the local sales tax rates and components for each city and county. See below.

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
  • Locally assessed values
  • Levy amounts, rates, and statutory maximum rates
  • 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 and does not include additional restricted sales taxes that the jurisdiction may have imposed.

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.

Cities and Towns

Last updated August 2018 to include EMS and affordable housing levies. Next update (2018 property taxes) anticipated in fall 2018.


For counties, this data distinguishes between total and unincorporated population, as well as general fund levies, road levies including diverted road funds and road levy shifts, and conservation futures levies.

Last updated July 2018. Next update (2018 property taxes) anticipated in fall 2018.

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.

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.
