December 31, 2025 for homestead classification affecting 2026 payable taxes; for 2027 payable taxes, own and occupy the property and apply by December 31, 2026; notify the assessor promptly after a change in homestead status.
Senior relief
Minnesota Property Tax Deferral for Senior Citizens: applicant must be 65 or older (if married, one spouse 65+ and the other at least 62), household income $96,000 or less, and have owned, lived in, and homesteaded the home for 5 years; property tax paid is limited to 3% of prior-year household income, with the state lending the remainder; apply by November 1, 2026 for 2027 taxes. This is a deferral loan, not forgiveness.
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.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
