Abstracts of Assessment, 1869-2015

Also included are valuations placed on miles of railroad, telegraph and telephone lines and other property by the Colorado Tax Commission. The “Dollar Wheel” shows how tax dollars were allocated. Later abstracts show the mill levies, valuations, and revenue for State, County, City and Town, School District, and Fire, Water and Sanitation District taxes.

Agricultural Statistics, 1882-1899
Series 102 (1 Volume + 1 Envelope)
In accordance with an act of the Fourth General Assembly in 1883 to collect and publish agricultural and other statistics, crop data was collected during the months of May and June each year by the County Assessor. The County's totals were then compiled and reported to the State by the County Clerk.
In the ledger book, each farmer is listed with his acreage and production of various crops, number of animals by type, and production of cheese, butter, oleomargarine, glucose, honey, and wool. Entries are chronological by year and then alphabetical by name of farmer (does not include location of land). This book was indexed by the Foothills Genealogical Society, index available in reading room.
In the report sent to the State, the County's totals of irrigated land, pasture land, acres and bushels of crops, orchard fruits, small fruits, number of animals, etc. are listed.
Also contains a draft of an 1874 report to the Secretary of the Board of Immigration on the Agricultural, Mining, and Manufacturing Advantages of Jefferson County.

Tax Levies, 1872-1970
Series 189 (3 Boxes)
Mill levy documentation for the various taxing districts in Jefferson County. The Assessor establishes the value of all property for tax purposes and taxing authorities use the assessed value to determine their mill levies. A mill levy is the number of dollars collectible for each $1,000 of assessed valuation. A mill is 1/10 of one cent, or $1 of revenue for each $1,000 of assessed valuation.
State taxes were levied by the State Board of Equalization. County taxes are set by the Board of County Commissioners. City and town taxes are set by city and town officials. Special school district levies were determined by school boards and voters of school districts while the current R-1 School tax is set by the school board. Fire, water and sanitation district taxes are set by their boards of directors.
Collection contains state and county orders of tax levy; state auditor’s report of taxes charged to the county; city and town certificates of levy; school district tax levy reports; tax levy resolutions for special districts; and other supporting documents such as budget reports, operating expenses, etc.
