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.

State Level
The Archives has a useful research tool from the state treasurer entitled. "Reports of Estates 1903-1913," which contains the date of death and the names of heirs of those who died testate. This record is arranged by county then by year.

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 taxes were instituted on them.
