Gathering Information

  • The Weston County Assessor is charged with the responsibility of identifying, valuing and assessing all personal property not specifically exempt by statutes. To meet this end procedures have been established and outlined as follows:
  • Identification of Businesses: Commercial and industrial operations are identified through various means such as sales tax lists, telephone books, advertisements, observations or word of mouth. New businesses are added to a historical listing of businesses in the Computer Assisted Mass Appraisal (CAMA) sub-system developed by the state. The information contained in this file is used to generate letters and forms sent to the businesses each year requesting updated reports/renditions of personal property. The timetable for the mailing of the forms is in December of each year and they must be completed and returned by the following March 1st.
  • Taxable Personal Property: All tangible personal property used in a business is taxable and must be listed. This will include (but not limited to) all furniture, fixtures, machines, computers, software, equipment, telephone systems, tools, manuals, unlicensed vehicles, mobile machinery, along with any small items used in a business. Leasehold improvements must be reported, but listed separately and clearly identified. Leased equipment must be listed in detail along with the name and address of the lease company. Inventory held for resale and licensed vehicles should not be reported.  Inventory items do not generate income.
  • Information Needed: To insure that a proper value is placed on each item of personal property, it is in the interest of the owner to list as much information as possible. The forms provided have columns for Description, Make, Model, Year Built, Serial Number, Installed Cost, Date Acquired and New/Used. If you paid separately for freight, installation, taxes or other fees, the cost must be either added to the item or listed separately and identified. The three most important columns are the Description, Installed Cost and Date Acquired. These will establish the category, trending and depreciation tables used in arriving at a value for tax purposes.
  • Property Location: This field on the personal property form must be completed to insure that the property is assessed in the appropriate tax district. A separate form should be completed for each location.
  • Update Reporting: After the first years reporting this office will generate and mail a personal property listing reflecting the information provided the previous year. Corrections, deletions and additions must be made to the forms and returned to this office by the March 1st deadline.


  • All property owners subject to taxation will be notified by the 4th Monday in April of each year with the mailing of Assessment Schedules. These schedules will have the estimated market value and assessed value of the property reported and as with all assessments must be appealed within 30 days of the date if the owner objects to the value.
  • If a business subject to personal property assessment fails to report or respond to inquiries An Estimate of Value will be placed on the property based on the best available information. All reports are subject to on-site review or audit for accuracy of reporting.

Owner Participation

  • Proper reporting of property is a responsibility and part of doing business. It aids in the fair and equal assessment intended by the constitution and supporting statutes.
