70.85(4)(b) (b) The department of revenue may revalue the property and adjust the assessment of the property to the assessment ratio of other property within the taxation district, if the department of revenue determines that:

70.85(4)(b)2. 2. The revaluation of the property can be satisfactorily completed without a reassessment of all property within the taxation district.

70.85(4)(b)3. 3. The revaluation can be accomplished before November 1 of the year in which the assessment is made or within 60 days of the receipt of the written complaint, whichever is later.

70.85(5) (5) Other property. In determining whether to revalue property under sub. (4), the department of revenue may examine the valuation of other property in the taxation district which is owned by the person filing the complaint.

70.85(6) (6) Tax computed on revalued amount. The valuation fixed by the department of revenue under this section shall be substituted for the assessed value of the property shown on the tax roll, and the tax shall be computed on the amount of the valuation determined by the department of revenue.

70.85(7)(a) (a) If the department of revenue has not completed the revaluation prior to the time established by a taxation district for fixing its tax rate, the taxation district shall base its tax rate on the total value of property contained in the assessment roll, including property whose valuation is contested under this section.

70.85(7)(b) (b) If the department of revenue has not completed the revaluation prior to the time of the tax levy, the tax upon property with respect to which the revaluation has not been completed shall be computed on the basis of the contested value of the property.

70.85(8) (8) Costs.

70.99(1) (1) A county assessor system may be established for any county by passage of a resolution or ordinance adopting such a system by an approving vote of 60 percent of the entire membership of the county board. After passage of this enabling resolution or ordinance by the county board, the county executive, or the county administrator, or the chairperson of the county board with the approval of the county board, shall appoint a county assessor from a list of candidates provided by the department of revenue who have passed an examination and have been certified by the department of revenue as qualified for performing the functions of the office. Certification shall be granted to all persons demonstrating proficiency by passing an examination administered by the department. The persons selected for listing shall first have been given a comprehensive examination, approved by the department of revenue, relating to the work of county assessor. A person appointed as county assessor shall thereafter have permanent tenure, after successfully serving the probationary period in effect in the county, and may be removed or suspended only for the reasons named in s. 17.14 (1) or for such cause as would sustain the suspension or removal of a state employee under state civil service rules. If employees of a county are under a county civil service program, the county assessor may, and any person appointed as a member of his or her staff shall, be incorporated into the county civil service program but tenure is dependent on the foregoing provision.

70.99(1m) (1m) Upon request of a county that is considering the creation of an assessment system under this section, the department of revenue may study the feasibility of that creation. The county shall reimburse the department for the costs of the study.

70.99(3) (3) 

70.99(3)(a) (a) The division of personnel management in the department of administration shall recommend a reasonable salary range for the county assessor for each county based upon pay for comparable work or qualifications in that county.

70.99(9) (9) In making the first assessment of any city, town or village the county assessor shall equalize the assessment of property within each taxation district. Thereafter, the county assessor shall revalue each year as many taxation districts under the county assessor’s jurisdiction within the county as the county assessor’s available staff will permit so as to bring and maintain each such taxation district at a full value assessment. The county assessor shall proceed with such work so as to complete the revaluation of all taxation districts under the county assessor’s jurisdiction within 4 years.

70.99(10)(b) (b) Two members of the board of review may hold the hearing of the evidence but a majority of the board members must be present to constitute a quorum at the meeting at which the determination of the issue is made. A majority vote of the quorum shall constitute the determination. In the event there is a tie vote, the assessor’s valuation shall be sustained.

70.99(10)(c) (c) A board member may not be counted in determining a quorum and may not vote concerning any determination unless, concerning such determination, such member:

If so established the county board of assessors shall investigate any objection referred to it by direction of the county board of review. The county board of assessors shall, after having made the investigation notify the person assessed or that person’s agent of its determination by first class mail, and a copy of such determination shall be transmitted to the county board of review. The person assessed having been notified of the determination of the county board of assessors shall be deemed to have accepted such determination unless that person notifies the county assessor in writing, within 10 days, of that person’s desire to present testimony before the county board of review.

70.99(10p) (10p) In counties that enter into a compact for a county assessor system, the board of review shall consist of 2 members appointed by each county with one additional member appointed by the county having the greatest full value.
