CO SB230

Prohibits the property tax administrator from considering certain percentages of telephone company intangible personal property in valuations, beginning with 20% exemption for tax year 2015 and increasing by 20% annually until complete exclusion in 2019.

Defines "intangible personal property" to include goodwill, software, customer lists, contracts, patents, trademarks, copyrights, trade secrets, franchises, and licenses (except federal communications commission licenses already excluded).

Requires the administrator to cap telephone company unit valuations at the net book value of tangible property, plant, and equipment as reflected in company records, adjusted for obsolescence, for all tax years after January 1, 2019.

Seeks to equalize property tax treatment between telephone companies (centrally valued) and cable companies offering telephone service (locally assessed with most intangible property exempt).

Takes effect 90 days after final adjournment of the 2015 general assembly, subject to voter approval if a referendum petition is filed.
