Pennington County Assessor's Office

The County Assessor's Office is responsible for estimating the market value and determining the legislative classification of all property in Pennington County for real estate tax purposes. Valuations must meet the standards established by Minnesota Statutes and the Minnesota Department of Revenue.


The estimated market value and classification are based on the condition and use of the property as of January 2nd of each year. Notices of values and classes are mailed to the property owners in the spring of the year. If they disagree with the value or classification or have a question on the notice they received they should contact this office. If they feel they need to appeal the value or class further, there is information on the Notice as to the process. After the appeal process, the values and classifications are set and used for property tax for the following year.

Homestead Classification

Properties which are occupied as a primary residence by the owner or a qualified relative of the owner may qualify for homestead. Occupants should contact the County Assessor's Office and fill out a homestead application or a relative homestead application. Homestead is a property tax reduction intended to keep taxes lower on owner/qualified relative occupied homes.


For your convenience, please find a blank copy of the Homestead Application below. In order to receive Homestead classification a homeowner must fully complete a Homestead Application and return to the Pennington County Assessor's office. Owners are not required to file a new application each proceeding year.  However, the Pennington County Assessor's Office may require a new application or other information to verify the homestead status. Owner's are "required" to inform the Assessor's Office within 30 days when vacating the property, or penalties may be incurred. New homeowners have until December 31st of the following year to file for homestead, provided they occupy the property by December 31 of the following year. Please contact the Pennington County Assessor's Office with any questions, (218) 683-7029.
