The City Assessor’s Office is responsible for the valuation of all real and personal property located within the City of Green Bay for tax purposes. It is our responsibility to ensure fair and equitable assessments throughout the City. It is our intention to use the most advanced assessment software to achieve uniformity on a regular basis.

The assessment procedure is governed by Chapter 70 of the Wisconsin state statutes and the Wisconsin Property Assessment Manual. The laws are very specific as to how the work is carried out. According to statute, the overall level of assessment must be within 10% of market value at least once in any 5 year period. Failure to comply with this requirement would result in a state-ordered City-wide reassessment paid for by the local government.


The Assessor’s Office neither sets the tax rate nor raises taxes to cover municipal budgets. Our valuation process operates independently of the budget and tax process.
