Hennepin County's regular 2026 open-book and board season is closed, but Minnesota's separate Tax Court route remains available for the January 2, 2026 assessment until April 30, 2027. That assessment determines taxes payable in 2027. The $249 FairPath owner-guided evidence packet is available now for every Hennepin County property. It can organize the valuation notice, parcel record, owner-verified facts, comparable sales, photographs, condition records, classification evidence, board materials, and Tax Court source documents. FairPath does not serve the County Auditor, file a court petition, pay filing or library fees, select a court division, choose an asserted value, or represent the owner.
Assessment context: Minnesota values and classifies property on January 2 for taxes payable the following year. Hennepin explains that use, condition, improvements, and classification affect the assessment; income-producing property may also be analyzed through rents, vacancy, and capitalization rates. The valuation notice identifies both the value and the appeal route. Some Hennepin cities maintain their own assessment offices, including Minneapolis, Bloomington, Brooklyn Park, Eden Prairie, Edina, Maple Grove, Minnetonka, and St. Louis Park. Other properties are assessed through Hennepin County. Start with the office and process printed on the notice rather than assuming one countywide informal filing method.
Filing process: Hennepin's informal review occurs in April and May by calling the assessor or attending an open-book discussion where offered. A formal board route ordinarily begins with the local board; if a city has transferred its board authority or does not hold a local meeting, the owner may proceed to the County Board of Appeal and Equalization. Hennepin's county meeting occurs in mid-June, and 2026 participating-city notices used May 20 as the county-board appointment deadline. Minnesota also provides a direct Tax Court route without requiring prior local or county board participation. The current Tax Court instructions require a real-property petition, property identification, service on the County Auditor, proof of service, filing with the district court, and a filing fee by April 30 of the payable year.
Evidence to review: Anchor evidence to January 2, 2026 and distinguish estimated market value, unequal assessment, classification, and exemption issues. Review the parcel record for land area, building size, age, quality, condition, use, improvements, and classification. Select arm's-length sales from the relevant Hennepin market and document sale date and price, parcel number, location, size, age, construction, condition, and material adjustments. Use dated photographs, inspections, repair scopes, permits, surveys, leases, rent rolls, and owner records to establish facts the mass appraisal may not capture. Preserve the valuation notice and any assessor or board correspondence. Tax Court instructions require property identification with the petition but specifically say not to attach an appraisal report to the initial petition.
Current deadline guidance: Tax Court deadline for the 2026 assessment: April 30, 2027. Hennepin County's informal discussions occur in April and May and its board process concludes in June. Published 2026 local materials used May 20 as the appointment deadline for the County Board of Appeal and Equalization, so the regular board season is closed. Minnesota separately permits a property-tax petition from May 1 of the assessment year through April 30 of the year taxes are payable. The January 2, 2026 assessment is payable in 2027, making the ordinary Tax Court petition deadline April 30, 2027.
The January 2, 2026 assessment affects taxes payable in 2027.
Hennepin routes some properties to city assessment offices and assesses the remaining jurisdictions through the county.
The regular local and county board activity occurs from April through mid-June and is closed for 2026.
Minnesota's separate Tax Court route remains available through April 30, 2027 and does not require a prior board appeal.
