Complaints of overvaluation or excessive valuation by reason of undervaluation or nonassessment of other property

1. Any person, firm, company, association or corporation, claiming overvaluation or excessive valuation of its real or secured personal property in the State, whether assessed by the Nevada Tax Commission or by the county assessor or assessors, by reason of undervaluation for taxation purposes of the property of any other person, firm, company, association or corporation within any county of the State or by reason of any such property not being so assessed, shall appear before the county board of equalization of the county or counties where the undervalued or nonassessed property is located and make complaint concerning it and submit proof thereon. The complaint and proof must show the name of the owner or owners, the location, the description, and the taxable value of the property claimed to be undervalued or nonassessed. 2. Any person, firm, company, association or corporation wishing to protest the valuation of real or personal property placed on the unsecured tax roll which is assessed between May 1 and December 15 may appeal the assessment on or before the following January 15, or the first business day following January 15 if it falls on a Saturday, Sunday or holiday, to the county board of equalization. 3. The county board of equalization forthwith shall examine the proof and all data and evidence submitted by the complainant, together with any evidence submitted thereon by the county assessor or any other person. If the county board of equalization determines that the complainant has just cause for making the complaint it shall immediately make such increase in valuation of the property complained of as conforms to its taxable value, or cause the property to be placed on the assessment roll at its taxable value, as the case may be, and make proper equalization thereof. 4. Except as provided in subsection 5 and NRS 361.403, any such person, firm, company, association or corporation who fails to make a complaint and submit proof to the county board of equalization of each county wherein it is claimed property is undervalued or nonassessed as provided in this section, is not entitled to file a complaint with, or offer proof concerning that undervalued or nonassessed property to, the State Board of Equalization. 5. If the fact that there is such undervalued or nonassessed property in any county has become known to the complainant after the final adjournment of the county board of equalization of that county for that year, the complainant may file the complaint on or before March 10 with the State Board of Equalization and submit his or her proof as provided in this section at a session of the State Board of Equalization, upon complainant proving to the satisfaction of the State Board of Equalization he or she had no knowledge of the undervalued or nonassessed property before the final adjournment of the county board of equalization. If March 10 falls on a Saturday, Sunday or legal holiday, the complaint may be filed on the next business day. The State Board of Equalization shall proceed in the matter in the same manner as provided in this section for a county board of equalization in such a case, and cause its order thereon to be certified to the county auditor with direction therein to change the assessment roll accordingly.
