This section does not mandate that January 1 is the date for determining tax exempt status for property owned by a charitable organization and does not address when the tax exempt status is to be determined. Family Tree Found. v. Prop. Tax Adm'r, 119 P.3d 581 (Colo. App. 2005).

City acquired an interest in the personal property prior to the date of the chapter 11 bankruptcy since the statute provides that a lien for ad valorem personal property taxes arises at 12 noon on the assessment date for the current year and such lien is a perpetual lien. Although the interest was an inchoate lien, the city was allowed to perfect it after the assessment date and thus have the lien relate back to the assessment date. Therefore the personal property taxes were a prepetition secured claim. In re W. States Distribs., Inc., 179 B.R. 666 (Bankr. D. Colo. 1995 ).
