How Sumner County Assesses Property

25%of market value

Assessed by: Sumner County Assessor of Property

Assessment cycle: 5-year

Notices typically mailed: April

The ASSESSMENT RATIO for the different classes of property is established by state law (residential and farm @ 25% of appraised value, commercial/industrial @ 40% of appraised value). The ASSESSED VALUE is calculated by multiplying the appraised value by the assessment ratio. If your home's market value is $246,900, at Tennessee's 25% assessment ratio your assessed value would be $61,725, resulting in approximately $1,876 in annual taxes at the county's effective rate of 0.76%.

The Appeal Process

Appeals are heard by the County Board of Equalization. The county board can review and change assessments on its own but generally it acts only after receiving a complaint from taxpayers who believe their assessments are too high. Board duties include examining and equalizing county assessments, hearing complaints of aggrieved taxpayers, decreasing over-assessed property, and correcting clerical mistakes.
