How Property Tax Works

Benton County, Minnesota operates under a property tax system that funds essential local services including schools, roads, public safety, and county operations. Property taxes are the primary funding source for these services, with tax rates determined annually based on approved budgets from various local government entities including the county, school districts, cities, and special taxing districts.

The effective property tax rate in Benton County varies significantly by location within the county due to different combinations of special taxing districts, school districts, and municipal boundaries. For the 2025 tax year, the estimated county portion of the tax rate is approximately 4.188%, though your total effective rate will be higher when combined with school district, municipal, and special district levies. Property owners should expect total effective rates typically ranging from 1.0% to 1.5% of market value, depending on their specific location and applicable districts. Tax statements are mailed annually by March 31st, and failure to receive a statement does not exempt property owners from timely payment obligations.

Supplemental Tax Bills

Supplemental taxes in Benton County are triggered when property changes ownership, undergoes new construction, or experiences significant improvements that increase the assessed value mid-year. These supplemental assessments ensure that tax obligations reflect current property values and ownership throughout the tax year.

When a supplemental assessment occurs, the additional tax is calculated by taking the difference between the new assessed value and the previous assessed value, then applying the current tax rate to that difference. The supplemental tax is prorated based on the number of months remaining in the tax year from the date of change. For example, if a $100,000 home improvement is completed in July (6 months into the tax year), and the total effective tax rate is 1.2%, the supplemental tax would be approximately ($100,000 × 1.2% × 6/12 months) = $600 for the remainder of that tax year.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for borrowers, collecting monthly tax payments along with principal and interest payments. Lenders typically collect 1/12th of the annual property tax amount each month and hold these funds in an escrow account until tax payments are due. In Benton County, this means lenders will make payments on your behalf by May 15th for the first half and by October 15th for the second half.

Property owners with escrowed taxes should verify that their lender has received the annual tax statement and confirm the correct payment amounts. When property values or tax rates change significantly, escrow payments may require adjustment, potentially resulting in escrow shortages or surpluses. Lenders are required to provide annual escrow analysis statements showing account activity and any necessary payment adjustments. If you receive a supplemental tax bill, notify your lender immediately as these may not be automatically included in your escrow calculations and could require separate payment.
