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
Most of the assessment or tax rolls for 1845 to 1900 are still located at the county courthouses. But some are deposited at the Oregon State Archives.

Oregon counties are required by law to keep their tax rolls through 1905 All subsequent records must be kept for fifty years before they are destroyed. The exception to this is for years ending in 0 or 5, which are kept for research samples.

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.
