Washington Tax Records
From Ancestry.com Wiki

Washington’s only tax records are for real and personal property, which were both levied at the county level. The records are held by the county assessors and the county treasurers. In some cases, the Washington State Archives’ regional branches have acquired older records. These branches are excellent places to begin searching for county tax records. Not all county tax records have survived. Inheritance tax records are on microfilm at the Washington State Archives from 1901 until the tax was discontinued in 1981.
