Senior relief
Minnesota Property Tax Deferral for Senior Citizens: applicant must be 65 or older (or one spouse 65+ and the other at least 62+), household income $96,000 or less, and must have owned, lived in, and homesteaded the home for five years; the homeowner pays up to 3% of household income and the state lends the remainder; apply by November 1, 2026 for 2027 taxes. This is a deferral loan, not forgiveness. Other relief may include the Homestead Credit Refund and qualifying disabled-veteran or blind/disabled programs.
Valuation limits
No general countywide annual valuation cap was verified in Minnesota. The county assessor establishes estimated market value under Minnesota law; homestead market-value exclusion and program-specific agricultural, forest, veteran, disaster, and deferral programs can reduce taxable market value. For 2026, the agricultural homestead first-tier valuation limit is $3,840,000; the homestead market-value exclusion is up to $38,000 and phases out at $517,200.
