How Property Tax Works

Fillmore County, Minnesota operates under the state's property tax system to fund essential local services including schools, roads, public safety, and county operations. Property taxes in Fillmore County are based on the estimated market value of your property, with tax rates varying depending on your specific location within the county due to different combinations of special taxing districts such as school districts, townships, and other local jurisdictions.

The effective tax rate in Fillmore County for 2025 ranges from approximately 0.33% for agricultural homestead properties to 1.01% for seasonal recreational residential properties, with residential homestead properties typically seeing an effective rate around 1.00%. However, your actual tax rate will depend on the specific taxing districts that serve your property location. Property owners should note that most tax credits and exemptions require formal application and are not automatically applied to your tax bill.

Supplemental Tax Bills

Supplemental taxes in Fillmore County are additional property tax assessments that occur when there are changes to your property after the regular assessment date. Common triggers include new construction, additions, renovations that increase property value, or changes in property ownership that affect classification or exemption status.

When supplemental taxes are levied, they are calculated based on the increased assessed value multiplied by the applicable tax rate for the remaining portion of the tax year. For example, if you complete a $50,000 home addition in July that increases your assessed value, you would owe supplemental taxes on that additional $50,000 value for the remaining months of the tax year. The Fillmore County Assessor's office will mail a supplemental tax statement separately from your regular property tax bill, and these amounts are typically due within 30 days of the statement date.

Escrow & Property Taxes

Most mortgage lenders in Fillmore County require property tax escrow accounts, where you pay 1/12 of your annual property tax bill with each monthly mortgage payment. Your lender collects these funds and pays your property taxes directly to Fillmore County on the due dates: May 15th for the first half and November 15th for the second half.

Lenders typically conduct annual escrow analyses to ensure adequate funds are collected, and may adjust your monthly payment if property taxes increase or decrease. You should receive an annual escrow statement showing all deposits and payments made on your behalf. If you pay your own property taxes, you can verify payments and balances through the Fillmore County Treasurer's office at 507-765-4701 or by visiting 101 Fillmore St., Preston, MN. Property owners are ultimately responsible for ensuring taxes are paid on time, even when using escrow services.
