Section 70.75 - Reassessments(1) REASSESSMENTS, HOW MADE. (a)1. The owners of taxable property in any taxation district, other than an assessment district within the corporate limits of any 1st class city, whose property has an aggregate assessed valuation of not less than 5 percent of the assessed valuation of all of the property in the district according to the assessment sought to be corrected, may submit to the department of revenue a written petition concerning the assessed valuation of their property. Subject to subd. 2. and sub. (1m), if the department finds that the assessment of property in the taxation district is not in substantial compliance with the law and that the interest of the public will be promoted by a reassessment, the department may order a reassessment of all or of any part of the taxable property in the district to be made by one or more persons appointed for that purpose by the department.2. The department may dismiss any petition for reassessment if, prior to the entry of a reassessment order under subd. 1., the taxation district involved determines under s. 70.055 that employing expert help to aid in assessing property would be in the public interest and if, after receiving departmental approval, the taxation district does employ expert help for either of the 2 years following the assessment year complained of.3. If the department performs the reassessment or special supervision under sub. (3), the department shall designate the person responsible for the reassessment. If the department appoints a corporation for the reassessment or special supervision under sub. (3), the corporation shall designate the person responsible for the reassessment. The corporate or departmental designee shall file the official oath under s. 19.01.4. If a petition under subd. 1. is filed in the office of the department the department shall, under the powers conferred by s. 73.03(1), review the assessment complained of. If the department finds the assessment is not in substantial compliance with law and that public interest will be promoted by a reassessment, it shall correct such assessment by a reassessment as provided in this section. The department's duty to reassess is not impaired by any action, subsequent to such filing, of any taxpayer represented in the application.5. As a part of its investigation of the assessment complained of, the department shall hold a hearing at some convenient place within or near the taxation district which is sought to be reassessed. At such hearing testimony may be offered as to the inequality or equality of the assessment, whether or not the public interest will be promoted by a reassessment and as to such other matters as may be desired by the department. Notice of the hearing specifying the time and place of the hearing shall be mailed to the clerk of the taxation district and the first signer of the application for reassessment, not less than 8 days before the time fixed for the hearing.6. The department shall keep on file its order directing such reassessment and naming the persons appointed to make the reassessment. In addition, the department shall transmit a copy of the order to the clerk of the taxation district, to the supervisor of equalization of the county in which the district is located and to each of the persons appointed to make such reassessment and serve on the board for the review of the reassessment. Service of a copy of the order is legal notice to these people of their appointment. No person may be authorized by the department to make a reassessment or to provide special supervision instead of reassessment unless the person is willing and able to use the assessment manual.(b) All assessment personnel appointed under this section in 1974 and thereafter shall have passed an examination and have been certified by the department of revenue as qualified for performing the functions of the office to which appointed. Any person appointed under par. (a) or sub. (3) shall be certified as an expert appraiser as provided in s. 70.055(1).(1m) ADDITIONAL REQUIREMENTS. The department may not proceed under sub. (1) (a) with respect to a petition filed by a property owner who owns more than 5 percent of the assessed valuation of all the property in a taxation district if within the 3 years preceding the date of the petition that person petitioned for reassessment and the department of revenue did not order a reassessment under sub. (1) or special supervision under sub. (3) unless, in addition to that property owner, an owner or owners of an additional 5 percent of the assessed valuation of the taxation district join in the petition. If a petition is denied under this subsection, the property owner who petitioned twice within a 3-year period shall pay 75 percent of the department of revenue's costs in respect to that petition. Payments under this subsection shall be made to the department of revenue for deposit in the appropriation under s. 20.566(2) (h).(2) PERSONS APPOINTED TO REASSESS, POWERS AND DUTIES. The person or persons appointed under sub. (1) to make a reassessment, without delay, shall severally take and subscribe an oath or affirmation to support the constitution of the United States and of the state of Wisconsin and to faithfully perform the duties imposed upon that person in respect to the reassessment to the best of that person's ability, and shall file the same with the department of revenue. Thereupon the person or persons appointed to make the reassessment shall proceed with diligence to make a reassessment of all the taxable property in the affected district. For that purpose the person or persons appointed to make the reassessment shall have all the power and authority given by law to assessors in the district and shall perform all the duties and be subject to all restrictions and penalties imposed by law upon assessors in the district. The person or persons appointed to make the reassessment shall have access to all public records and files which may be necessary or useful in the performance of the reassessment, and while engaged therein shall be entitled to have custody and possession of the roll containing the original assessment in the district and all property and other statements and memoranda relating thereto. A blank assessment roll and all property statements and other blank forms necessary for the purposes of the reassessment shall be furnished by the county clerk at the expense of the county upon the application of the department of revenue.(3) SPECIAL SUPERVISION INSTEAD OF REASSESSMENT. Whenever the department determines, after the hearing provided for in sub. (1) or in the determination under s. 70.05(5) (d), that the assessment complained of was not made in substantial compliance with law but that the interests of all the taxpayers of such district will best be promoted by special supervision of succeeding assessments to the end that the assessment of such district shall thereafter be lawfully made, it may proceed as follows: It may designate one or more employees of the department or appoint one or more other qualified persons to assist the local assessor in making the assessments to be thereafter made in such district. Any person so appointed may give all or such part of that person's time to such supervision as, in the judgment of the department, is necessary to complete such assessment in substantial compliance with the law, and in performing such task shall have all the powers given by law to any person designated to make a reassessment and together with the assessor shall constitute an assessment board as defined in s. 70.055.(4) COSTS. Except as provided in sub. (1m), all costs of the department of revenue in connection with reassessment or special supervision under this section shall be borne by the taxation district. These receipts shall be credited to the appropriation under s. 20.566(2) (h). Past due accounts shall be certified on or before the 4th Monday of August of each year and included in the next apportionment of state special charges to local units of government.(5) DEFINITIONS.
