Neb. Rev. Stat. § 77-801

(1) All public service entities shall, on or before April 15 of each year, furnish a statement specifying such information as may be required by the Property Tax Administrator on forms prescribed by the Tax Commissioner to determine and distribute the entity's total taxable value including the franchise value. All information reported by the public service entities, not available from any other public source, and any memorandum thereof shall be confidential and available to taxing officials only. For good cause shown, the Property Tax Administrator may allow an extension of time in which to file such statement. Such extension shall not exceed fifteen days after April 15. (2) The returns of public service entities shall not be held to be conclusive as to the taxable value of the property, but the Property Tax Administrator shall, from all the information which he or she is able to obtain, find the taxable value of all such property, including tangible property and franchises, and shall assess such property on the same basis as other property is required to be assessed. (3) The county assessor shall assess all nonoperating property of any public service entity. A public service entity operating within the State of Nebraska shall, on or before January 1 of each year, report to the county assessor of each county in which it has situs all nonoperating property belonging to such entity which is not subject to assessment and assessed by the Property Tax Administrator under section 77-802 . (4) For tax years prior to tax year 2020, the Property Tax Administrator shall multiply the value of the tangible personal property of each public service entity by the compensating exemption factor calculated in section 77-1238 .
