In order to ensure accurate property assessments, the Pennington County Director of Equalization office conducts regular reappraisal and data review projects. If, at any point, you discover incorrect property data on a residential property you own, please contact the Equalization office by phone or use the form below to update your property information. The online property data update form is available from May 1st to December 31st each year to ensure that any corrections can be applied for the subsequent annual assessment.
To best aid with the property data update, please provide your Neighborhood and Tax ID numbers. These can be found using the Pennington County Property Search. Simply enter your name or property address and select your property from the displayed list. The selected Neighborhood and Tax ID number for the property can be found here under General information.
If any questions should arise from your provided property data update, an appraiser working that area will be in contact.
