Property tax bills in Sullivan County are based on the assessed value of a home, not its market price alone. Local taxing authorities apply the county’s tax rate to that assessed value to determine the annual bill, so two homes with similar market values can still owe different amounts if their assessments differ.

With a median home price of $120,300, homeowners can see a wide range in what they owe. The 25th percentile tax bill is $437, while the 75th percentile is $1,131 and the 90th percentile reaches $1,722.
That variation means property taxes can have a meaningful effect on household budgets, especially for homeowners whose assessments rise over time. Even within the county, median tax bills differ by city, from $455 in Rogersville to $1,096 in Piney Flats, showing how local conditions can influence what homeowners ultimately pay.
