Blue Earth County Overview
How Blue Earth County Property Taxes Work
Blue Earth County covers Mankato and North Mankato along with surrounding agricultural townships in southern Minnesota. The county manages a wide range of property types: commercial buildings in downtown Mankato, suburban residential neighborhoods, and farmland in the outer townships. All real and taxable personal property is assessed as of January 2 each year under Minnesota Statutes Chapter 273.
Tax statements are mailed by March 31. The first half of your property tax is due May 15. The second half is due October 15. If the full bill is under $100, you can pay it in one installment by May 15. Payments past the due dates accrue interest under Chapter 279. Properties with long-term unpaid taxes can enter a forfeiture process, with the county eventually offering tax-forfeited land for sale under Chapter 282.
Each fall, Blue Earth County and all local taxing districts set their levies through the Truth in Taxation process under Chapter 275. This process requires public notice before levies are finalized in December. The Minnesota DOR publishes levy and assessment data for all counties including Blue Earth at revenue.state.mn.us.

Blue Earth County Assessor
The Blue Earth County Assessor values all real property annually and maintains the records that feed into the tax calculation. The office is at 204 S 5th Street in Mankato. Phone is (507) 304-4255. The assessor page at blueearthcountymn.gov/departments/assessor covers valuation methodology, homestead applications, and how to start an appeal.
Assessors in Blue Earth County inspect properties on a regular cycle to confirm condition, size, and any improvements or changes. Under Chapter 273, all property must be valued at estimated market value unless a special classification applies. For commercial properties in Mankato, the assessor may use an income approach to value. For residential homes, comparable sales from the local market drive the valuation. Agricultural land in the outer townships uses a productivity value approach for some classifications.
If you have made major improvements to your property or believe neighboring comparables are valued lower than yours, contact the assessor. Bringing in a recent appraisal or sales of similar properties strengthens your case for an adjustment.

Homestead Classification in Blue Earth County
Homestead status reduces your property tax by applying a lower class rate to your primary residence. To qualify in Blue Earth County, you must own the property, occupy it as your main home by December 1, and apply with the assessor by December 31. You submit your Social Security number or ITIN, which is used to verify the property is truly your primary residence and not a rental or second home.
Once your homestead is approved, it stays until you sell, move out, or convert the property to another use. Mankato has an active real estate market, and the assessor processes a significant number of homestead applications each year. If you bought a home in Blue Earth County and have not yet applied, do so as soon as possible to get the lower rate for the next tax year. The classification under Chapter 273 can make a real difference in your annual bill.
The Minnesota Property Tax Refund through Form M1PR may also help qualifying households in Blue Earth County. The program is run by the Minnesota Department of Revenue and provides relief for low-to-moderate income homeowners and renters whose property tax burden is high relative to their income.
Note: Relative homestead, which applies when a qualifying relative of the owner lives in the home, has additional eligibility rules under Chapter 273 and requires its own application.
