Downloadable tax charts for the state of Washington can be found on the state's Department of Revenue website. Tax rate charts are available in a variety of easy-to-read PDF, Excel and QuickBooks file formats.
To aid in finding the Washington state tax rate for the precise area that the user is looking for, the site provides the information grouped by city and county. The rate information is also presented quarterly by year. In 2015, tax rate information was available from the year 2009 and later.
The tax charts arranged by city and county include the location code for each city, local tax rate for that city, the state tax rate and the combined rate for the two. The charts also include effective dates for the implementation of new tax rates for the areas. The county-only tax-rate charts include the same information as the city tax charts plus information on new taxes and boundary changes that may affect the locations of cities.
Along with the tax-rate charts, the Department of Revenue site also contains any tax forms necessary to file the taxes as well as detailed payment instructions. There is also the option provided to file a resident's state taxes online.
