Assessment Rolls and Tax Lists, 1866-1948

Identifier: Series-100

Scope and Contents

Assessment rolls and tax lists generally indicate a property owner's name, legal description of land or town lot owned, assessed value of the land, assessed value of improvements on the land (but no indication of what the improvements were), total tax assessed and the amount of taxes apportioned to state, county, town and school district. Books for later years list tax levy and revenue information.

The assessment rolls dated 1871-1893 show the number and assessed value of personal property the person may have owned such as animals, clocks and watches, musical instruments, carriages, etc.

From 1928 to 1936, taxes on automobiles were recorded in special volumes. These books include the person's name, address, year and make of the automobile owned, its valuation, and the amount of tax and date it was paid.

Taxes levied for the Moffat Tunnel are recorded in separate volumes from 1928 to 1941. These books include property owner's name, address, legal description of land owned, assessed value and the amount of the specific tax levied for the Moffat Tunnel district.

Assessment rolls and tax lists can be used to trace when an individual was in Jefferson County and where their property was located, how much property they owned, what kind of car they drove, approximate date a school district was created, dates a business was operating, and much more.
