Why Use Tax Records
By studying several consecutive years of tax records you may determine when a young men came of age, when individuals moved in and out of a home, or when they died leaving heirs. Authorities determined wealth (real estate, or income) to be taxed. Taxes can be for polls, real and personal estate, or schools.

Tax record content varies and may include the name and residence of the taxpayer, description of the real estate, name of original purchaser, description of personal property, number of males over 21, number of school children, slaves, and farm animals. Tax records usually are arranged by date and locality and are not normally indexed. Tax records can be used in place of missing land and census records to locate a person’s residence.

County Level
Washington's only tax records are for real and personal property, which were both taken 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.

Tax Laws
Abraham Lincoln instituted the income tax in 1862, and on July 1, 1862, Congress passed the Internal Revenue Act, creating the Bureau of Internal Revenue (later renamed to the Internal Revenue Service). This act was intended to “provide Internal Revenue to support the Government and to pay interest on the Public Debt.” Instituted in the height of the Civil War, the “Public Debt” at the time primarily consisted of war expenses. For the Southern States that were part of the Confederate side of the Civil War, once Union troops took over parts of the Southern States, income tax were instituted on them.

What history has shown us is that while property taxes are locally levied, there is significant state involvement with the amount of tax local political subdivisions can levy, how property assessments are conducted, and what services local taxing subdivisions must provide for their residents. This comes at a cost to state taxpayers, because the state has obligations it must fund as well, with a limited amount of state tax dollars.
