(a) Except as otherwise provided in this paragraph (a), no later than April 1 of each year, each public utility doing business in this state shall file with the administrator, on a form provided by the administrator, a statement, signed by an officer of such public utility under the penalties of perjury in the second degree, containing such information concerning itself and all of its property, wherever situated, as the administrator may reasonably require for the purpose of determining the actual value of such public utility in this state and for apportioning the valuation for assessment of such public utility among the several counties of this state. Upon good cause shown, the administrator may grant an extension for filing such statement to any public utility. Any extension granted pursuant to this paragraph (a) shall be for a reasonable amount of time as determined by the administrator.

(b) Such statement shall include a specific identification of each and every item of property owned, leased, or used which is not included in the rendition of the operating property and plant and the county in which each item is located.

(1.5)

(a) If a public utility fails to complete a statement of property and legally postmark it for return by April 1, the administrator shall impose on such public utility a late filing penalty in the amount of one hundred dollars for each calendar day the statement of property remains delinquent; except that the late filing penalty shall not exceed three thousand dollars. If, by June 1, the public utility continues to be delinquent in filing a statement of property, the administrator shall, in addition to imposing a late filing penalty, determine the actual value of such utility on the basis of the best information available. All late filing penalties shall be credited to the general fund.

(b) If any public utility fails to file a completed statement of property, or includes in a filed statement of property any information concerning the public utility property which is false, erroneous, or misleading, or fails to include in the statement of property any taxable property owned by the public utility, then the administrator may determine the actual value of such taxable property on the basis of the best information available.

(c) If a public utility fails to file a statement of property and does not file a petition or complaint pursuant to section 39-4-108 regarding the actual value of its taxable property as determined on the basis of the best information available pursuant to this subsection (1.5), the public utility shall be deemed to have waived any right to file an abatement or refund petition regarding such actual value pursuant to section 39-10-114.

(2) All such statements filed with the administrator shall be considered private documents and shall be available only to the administrator and the employees of the division of property taxation and to assessors.
