How Property Tax Works

Grundy County, Missouri operates under a property tax system that funds essential local services including schools, roads, law enforcement, and county operations. Property taxes are the primary revenue source for these services, with rates determined by various taxing jurisdictions within the county. The effective tax rate in Grundy County is relatively low compared to many Missouri counties, with the base county rate at 0.35% for levy year 2025.

Actual property tax rates vary significantly by location within Grundy County due to overlapping special taxing districts, including school districts, fire protection districts, ambulance districts, and road districts. Property owners may pay different rates depending on which combination of these districts serve their specific address. The county also maintains a Special Road and Bridge fund that receives additional property tax revenue to support transportation infrastructure throughout the county.

Supplemental Tax Bills

Supplemental property taxes in Grundy County are additional assessments that occur when there are changes to property ownership, value, or use outside the regular assessment cycle. Common triggers include new construction completion, property improvements, ownership transfers that remove exemptions, or discovery of previously unassessed property improvements.

Supplemental taxes are calculated by applying the current tax rate to the difference between the old and new assessed values, prorated for the portion of the tax year remaining. For example, if a $50,000 home addition is completed in January and assessed at $10,000, with a total tax rate of 0.8%, the supplemental tax would be approximately $80 for the full year. The Special Road and Bridge fund also receives 5% of property tax collections, which may affect supplemental tax calculations for road district properties.

Escrow & Property Taxes

Most mortgage lenders in Grundy County require property tax escrow accounts to ensure timely payment of property taxes. Lenders collect monthly escrow payments equal to 1/12th of your annual property tax bill, plus a small cushion amount. These funds are held in a separate escrow account and used to pay your property taxes when they become due on June 13th and September 5th each year.

Lenders are required to provide annual escrow statements showing collections, payments, and account balances. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment will be adjusted accordingly. Property owners can verify their tax payments through the Grundy County Treasurer's office and should review their escrow statements annually to ensure accuracy. Overpayments are typically refunded or credited to the following year's escrow account.
