Assessment and Tax Rolls
Series documents the assessment of real and personal property, the determination of tax liability, and the collection of county taxes. Assessment, tax, and delinquent tax records are variously labeled as rolls, lists, or summaries. Records show property owner; description and value of urban and agricultural land, personal property, and livestock; assessments, equalizations, and taxes due; and notations on payment and delinquency in payment of taxes. Beginning with 1900, counties have only been required to retain permanently those assessment and tax rolls for years ending in "0" and "5."
