Office of the Assessor of Real Estate
King William County Assessor's Department conducts assessments of all real property based on fair market value. Mass appraisal procedures are utilized to determine assessed values. Mass appraisal is defined by the International Association of Assessing Officers (IAAO) as "the process of valuing a group of properties as of a given date, using standard methods, employing common data, and allowing for statistical testing." The mass appraisal method is the industry standard for tax assessment purposes and is necessary to accomplish the valuation of the thousands of parcels located in the County.
Review & appeals process
The Assessor's Department will send a notice to each property owner upon completion of a reassessment. The following are general guidelines for the appeals process:
- Administrative Review: If after you receive and review your Notice of Real Estate Assessment Change you note any errors or corrections or wish to request a review, reconsideration or explanation of your determined reassessed value, the property owner or an Authorized Agent may do so by scheduling an appeal with the assessor by the deadline.
Second Assessment Notices for results in appeals held between October 19, 2020 through November 13, 2020 were mailed on December 23, 2020. If you had an appeal and did not receive a second notice please contact us.
