From Cook County MN - March 30, 2020

On Saturday, March 28, Governor Walz signed legislation extending the time for filing property tax petitions for contesting 2019 value or classification to May 30, 2020. 

In another move to aid in following social distancing rules recommended by public health experts, Cook County will waive personal service of property tax petitions contesting 2019 value or classification so long as property owners meet certain conditions. 

Cook County will accept service of Tax Court petitions by email (preferred) or mail. Emailed petitions shall be directed to: [email protected] Mailed petitions shall be sent to:

Cook County Auditor
411 W 2nd Street
Grand Marais, MN 55604

Petitions must include an admissions of service page (already included as page 2 of Minnesota Tax Court Form 7). County staff in the Attorney’s or Auditor’s Office will acknowledge service by signing this page. After all signatures have been applied, the county will email the petition and proof of service to the petitioner. The county will work to return petitions with the completed proof of service the same day they are received. If no email is provided, the petition and proof of service will be returned by mail.

It is the responsibility of the petitioner to timely file the petition with proof of service with the district court. Updates on the status of the district court can be found on the Minnesota Judicial Branch website ( More information about the filing process may be found on the Minnesota Tax Court website (
