Best Minnesota Property Tax Appeal Services in 2026 (Compared)
Last updated: June 26, 2026
Minnesota property tax appeals are filed as petitions to the Minnesota Tax Court, or through the informal local appeal process (County Board of Appeal and Equalization) which meets in April-June. The Tax Court petition deadline is April 30 (for properties assessed January 2). Minnesota uses estimated market value as the assessment basis. Hennepin County (Minneapolis), Ramsey County (St. Paul), Dakota, Anoka, and Washington counties have high property values and significant appeal activity. On a $450,000 Twin Cities home at a 1.2% rate, a 10% reduction saves $540 per year.

How to Choose the Right Service
Minnesota has two appeal pathways: the informal County Board of Appeal (April-June) and the formal Tax Court (petition by April 30). AppealDesk evidence works for both. The Twin Cities metro has seen significant appreciation, making flat-fee services more economical than contingency for savings above $200/year.
