How Property Tax Works

Miller County, Missouri operates under the state's property tax system to fund essential local services including schools, fire protection, road maintenance, and county operations. Property taxes in Miller County are calculated based on assessed values determined by the County Assessor, with tax rates set annually by various taxing jurisdictions including the county, school districts, fire protection districts, and other special districts.

The effective tax rate in Miller County typically ranges around Missouri's statewide average of approximately 1% of assessed value, though actual rates vary significantly depending on your specific location within the county. Properties within different fire protection districts, school districts, and municipal boundaries will have different total tax rates. The county uses a fractional assessment system where residential property is assessed at 19% of true value in money, while other property types have different assessment ratios.

Your total property tax bill represents the combination of levies from multiple taxing entities that serve your property. Due to the variety of special taxing districts throughout Miller County, two similar properties may have different tax rates depending on which fire district, school district, or other special service areas they fall within.

Section 4

Supplemental Tax Bills

Supplemental taxes in Miller County may be levied when there are changes to property ownership, new construction, or significant improvements that affect the assessed value during the tax year. The Missouri property tax system typically assesses properties on a biennial basis, but changes in ownership or substantial improvements can trigger reassessment.

Supplemental taxes are calculated based on the difference between the new assessed value and the previous assessed value, multiplied by the applicable tax rate, and prorated for the portion of the tax year remaining. For example, if you complete a major home addition mid-year that increases your assessed value by $20,000, you would owe supplemental taxes on that increase for the remaining months of the tax year.

The County Collector reviews additions and abatements entered into the property tax system throughout the year. Property owners are responsible for paying any supplemental taxes that result from these changes, even if a separate bill is not received, as taxes remain due by the December 31 deadline regardless of billing status.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Miller County require property tax escrow accounts for homeowners with less than 20% equity. Your lender collects monthly escrow payments along with your mortgage payment and pays your property taxes directly to the Miller County Collector when they become due on December 31st each year.

Lenders typically conduct annual escrow analyses to ensure adequate funds are collected. If property taxes increase due to reassessment or rate changes, your monthly escrow payment may be adjusted accordingly. You'll receive an escrow analysis statement showing any shortage or surplus, with payment adjustments spread over 12 months.

Property owners are encouraged to verify that their lender has paid property taxes on time, as the property owner remains ultimately responsible for tax payment regardless of escrow arrangements. You can verify payment status through the Miller County Collector's Office or online payment portal if available.
