About Business Personal Property
The Personal Property Section of the Assessor’s Office establishes values for business personal property (the assets owned by businesses) for ad valorem property tax purposes.
By April 15 of every year, businesses in Boulder with a total actual value of their personal property assets greater than $7,400 are required to send the Boulder County Personal Property Section a declaration listing all the assets they owned as of January 1, along with information regarding the original date and cost of acquisition for those assets. Even if assets were disposed of after January 1, they must be declared because current Colorado law does not provide for prorated assessments. The Assessors Personal Property staff takes the information provided by the taxpayer and calculates a value for each business; a Notice of Valuation is mailed by June 15.
If you have also filed a paper declaration, please note that on your online form.
The Assessor is located at 1325 Pearl St. Courthouse, Boulder on the Pearl Street Mall. The mailing address is: PO Box 471, Boulder, Colorado 80306.

Leasing Companies can also call this number.
