The Otter Tail County Assessor’s Office values and classifies all types of real and personal property in Otter Tail County. The market values and classifications of taxable property are primary factors in the calculation of property taxes. The Office operates under Minnesota State Statutes, Minnesota Department of Revenue directives and County Board directives.

The use classification for each property is determined by the assessor. Applications for various use classifications, including homestead, agriculture, and exempt are processed by the assessor’s office. Please see the Property Tax Fact Sheets to see if you qualify for certain classifications.


  • Valuation notices are sent each spring showing the value assessed for taxes payable the following year. If the value is believed to be incorrect, please visit the Appeals Process.
  • Property tax statements are mailed to all property owners by March 31 of each year. This statement is the final property tax amount owed for the current year.
  • Truth in Taxation notices are sent to all property owners each November, before local governments finalize their budgets for the coming year.


The Appeals Process takes place every spring and public meetings are held to discuss valuation and classification for those who believe that your Estimated Market Value or Classification is incorrect based on their valuation notice received in the spring. You may search the dates, times and location of each meeting here once available or visit our News & Meetings tab at the top of the page.
