What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Unicoi County, TN

Unicoi County’s effective property tax rate of 0.524% sits above Tennessee’s statewide median of 0.467%, placing it 26th among the state’s 95 counties. That ranking signals a county taxing somewhat more heavily than the state as a whole. Against the national median of 0.794%, however, Unicoi County looks considerably lighter. A median home value of $189,600 produces a median annual real-estate tax bill of $994. With median household income at $52,218 and per-capita income at $30,307, that bill amounts to a noticeable but not overwhelming share of household earnings. Erwin, the county’s largest town, along with Flag Pond and Unicoi, falls under this rate. The picture is a county that leans above its own state’s norm yet remains below what many American homeowners pay.

Frequently asked questions

What is the property tax rate in Unicoi County, TN?
The effective rate is 0.52% — meaning the median tax bill equals about 0.52% of the median home value.
How much are property taxes on a median home?
On the median home ($189,600), the estimated annual bill is about $994.
Is Unicoi County's rate high or low?

How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Unicoi County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Unicoi County assessor within the local deadline, typically with comparable sales as evidence.
