How Big Stone County Property Taxes Work

Big Stone County is one of Minnesota's smallest counties by population. It sits in the far west of the state along the South Dakota border. Most of the land in the county is agricultural, with cropland, pasture, and some wetland making up a large share of total acreage. Ortonville is the county seat and the largest community. The county assessor values all real and personal property each year as of January 2 under Minnesota Statutes Chapter 273.

Tax statements go out to property owners by March 31 each year. Taxes are split into two equal halves. The first half is due May 15. The second half is due October 15. If the full tax owed is less than $100, you can pay it all at once by May 15. Late payments accrue interest under Chapter 279. Parcels with unpaid taxes for several years can eventually move into forfeiture and be managed under Chapter 282 for tax-forfeited lands.

The county, along with cities, townships, school districts, and special districts, sets its levy each fall. The Truth in Taxation process under Chapter 275 provides public notice before the levies are finalized in December.

Note: Agricultural land in Big Stone County is classified and taxed differently than residential or commercial property, with class rates tied to the productivity value of the land.

Big Stone County Assessor

The Big Stone County Assessor values all real property in the county annually. The office is in Ortonville at 20 2nd Street SE. The main county phone line is (320) 839-3478. The assessor handles homestead applications, agricultural classifications, and valuation disputes before they reach a formal board hearing.

Given the county's agricultural character, the assessor spends much of the work year dealing with farmland valuations. Agricultural land in Minnesota has its own classification under Chapter 273, using a productivity-based value rather than market value for some classes of farmland. Understanding your land's classification is important. If your cropland is classified as agricultural homestead versus non-homestead, the tax difference can be meaningful.

The assessor also handles green acres elections and other agricultural deferral programs. If you use your land for farming and want to know if any deferral programs apply, talk to the assessor directly. These programs can reduce current-year taxes on qualifying land while allowing for future recapture when land use changes.

Tax Payments and the Big Stone County Treasurer

The Big Stone County Treasurer collects property taxes and manages the billing cycle. The treasurer's office is at 20 2nd Street SE in Ortonville, the same building as the assessor. Tax statements are out by March 31 each year. You can pay in person, by mail, or through any online payment option the county makes available. The treasurer's page at bigstonecounty.gov/treasurer has current payment details.

If you have a mortgage with an escrow account, your lender typically pays the taxes directly. You should still check the county's records each year to confirm the payment was made and posted correctly. Errors in escrow payments do happen, and you are ultimately responsible for your taxes regardless of your lender's actions.

The Minnesota Department of Revenue publishes statewide property tax data and statistics at revenue.state.mn.us/property-tax-data-and-statistics. This includes Big Stone County levy and assessment data going back several years.

Homestead and Agricultural Classifications

Homestead classification is available for your primary residence in Big Stone County. Contact the assessor to apply. You need to own the home, live in it as your main residence by December 1, and submit the application by December 31. The homestead class rate under Chapter 273 is lower than the non-homestead rate, which reduces your tax bill each year you qualify.

For agricultural land, the agricultural homestead classification applies when the farm operator lives on or very near the property. Big Stone County has a large amount of cropland, and most qualifying farmers should already have agricultural homestead status. If you are not sure, check with the assessor. It is worth verifying your classification is correct, especially if you recently acquired the property or changed how it is operated.

The Minnesota Property Tax Refund through Form M1PR is also available to Big Stone County residents who meet the income requirements. This state credit is handled by the Minnesota Department of Revenue. Both homeowners and renters can qualify depending on their income and property tax burden.

Big Stone County Recorder and Land Records

The Big Stone County Recorder files deeds, mortgages, and other documents that affect property ownership. The recorder's page is at bigstonecounty.gov/recorder. When a property sale occurs and a deed is recorded, the recorder's office captures the transaction. That sale data then flows to the assessor for use in the annual sales ratio study that drives area-wide value adjustments.

The deed tax paid at recording in Big Stone County follows MN Statutes Chapter 272. Recorded land records in the county are useful for verifying ownership, researching liens, and understanding the history of a specific parcel.

From there you can appeal to the County Board, and ultimately to the Minnesota Tax Court under Chapter 278. The Tax Court's number is (651) 539-3260 and its website is mn.gov/tax-court.
