Chapter 70.32(1) Wisconsin Statutes
(1) Real property shall be valued by the assessor in the manner specified in the Wisconsin property assessment manual provided under s. 73.03(2a) from actual view or from the best information that the assessor can practicably obtain, at the full value which could ordinarily be obtained therefore at a private sale. In determining the value, the assessor shall consider recent arm's-length sales of the property to be assessed if according to professionally acceptable appraisal practices those sales conform to recent arm's-length sales of reasonable comparable property; recent arm's-length sales of reasonably comparable property; and shall all factors that, according to professionally acceptable appraisal practices, affect the value of the property to be assessed.
The mission of the Assessor’s Department is to prepare the annual assessment roll (the official record of taxable and exempt property within the City of Marshfield), while providing the best possible service. Assessed values determine the amount of general property tax charged to each property owner, while the information gathered provides a historical record and reference base for municipal operations. The primary departmental goal is to reconcile fair and equitable assessments, emphasizing objective, defendable and effective, mass appraisal techniques.
Wisconsin Statutes, Chapter 39 (1975) define State certification requirements for assessment personnel to legally perform prescribed duties for the 1,897 jurisdictions in Wisconsin. The City of Marshfield requires an Assessor II certification to sign the tax roll. Continuing accredited education in appraisal, property tax law, and supervisory management, along with mandatory attendance at annual Department of Revenue training sessions, will satisfy re-certification requirements while assuring avenues for proficiency and professionalism.
The Assessor works pro-actively in conjunction with professional organizations and the Wisconsin Department of Revenue (on behalf of City of Marshfield property owners) regarding proposed legislation or procedural changes affecting the taxation process. Work programs and services are subject to review by the Department of Revenue and must comply with the "Wisconsin Property Assessment Manual", Wisconsin Laws, and the "Uniform Standards of Professionally Acceptable Appraisal Practices".
The Assessor’s Staff observes the Code of Ethics of the International Association of Assessing Officers, and the Codes of Ethical Behavior defined by Wisconsin Statute, Section 19.59. The codes establish clear and precise ethical and professional guidelines for assessing officers to discharge their duties to the public, while providing standards to judge professional conduct.
