Inquire About or Appeal an Assessment
If you have questions or disagree with your property classification or current year's estimated market value, please contact the Assessor's Office to discuss your concerns.
Informal appeal options
According to state law, Assessing Services cannot review or change the 2026 estimated market value of a property after the Special County Board of Appeal and Equalization meeting was adjourned. The county held this meeting on June 8, 2026. Assessing Services can no longer consider informal appeals of the 2026 valuations.
Assessing Services is still available to answer questions and review property characteristics, but changes can only be made relating to the 2027 assessment (for taxes payable in 2028).

The County Attorney's Office has outlined alternative services for 2026 property tax petitions.
Dakota County alternative service methods
The followng procedures will apply until further notice.
Minnesota Statute 278.01 requires personal service of one copy of a property tax petition upon the County Auditor/Treasurer. For all counties, each petitioner must file a copy of the petition with proof of service, in the office of the court administrator of the district court, on or before April 30 of the year in which the taxes become payable.
Acceptable alternative service of tax petitions on Dakota County entities
The Dakota County Auditor/Treasurer's Office is currently accepting email service of property tax petitions. The county has set up a special email address for service of tax petitions. A scanned copy of a complete property tax petition (including the front, back and any additional pages) received by the county at this designated email address will satisfy the service requirement on the County Auditor/Treasurer.
Service instructions
1. Email service of property tax petitions for Dakota County properties can be accomplished by emailing the petition to taxpetitions@co.dakota.mn.us.

Acknowledgement of service
Upon receipt of a property tax petition by the email service described above, the county will issue the petitioner an acknowledgment of service by email. This shows the required county departments have been served. This acknowledgment must be filed in district court with the property tax petition.
Petitioners are advised to serve property tax petitions in advance of the April 30 filing deadline each year to allow time for return of the acknowledgment of service.
