Norris Lake Property Tax by County

How Tennessee Property Tax Works

Tennessee calculates property tax in three steps. First, the county assessor determines the appraised value — the estimated market value of the property. Second, that appraised value is multiplied by the state-mandated assessment ratio: 25% for residential and farm property. The result is the assessed value. Third, the assessed value is multiplied by the county's tax rate, expressed in dollars per $100 of assessed value. There is no state property tax in Tennessee; every dollar you pay goes to the county and, in some cases, a city if the property falls within incorporated limits.

For a $600,000 lakefront on Norris Lake, the assessed value is $150,000 (25% of $600,000). That $150,000 figure is what the county rate gets applied to — not the full $600,000 market value. This is why Tennessee's effective property tax burden is lower than most states even when nominal rates look similar to other places.

The Five-County Rate Table

Anderson County: The 2025 Reappraisal You Must Understand

Anderson County — which contains Norris Dam and the most accessible southern end of the lake — completed a countywide property reappraisal in 2025, the first in five years. This is critically important for any buyer looking at Anderson County lakefront right now. Before the reappraisal, the county rate was $2.6289 per $100 assessed value. After any reappraisal, Tennessee law requires the county commission to adopt a new "certified rate" — a lower nominal rate that keeps total tax revenue roughly the same despite higher assessed values.

What this means in practice: if Anderson County lakefront values rose significantly (which they did, given the 2020-2024 appreciation cycle), the new certified rate will be substantially lower than $2.6289. A county where values rose 40% might adopt a new rate around $1.88 to remain revenue-neutral. But until the Anderson County Commission formally adopts the new rate for fiscal year 2025-2026, no one can give you the confirmed number — not the listing agent, not Zillow, and not this page.

The practical advice: call the Anderson County Trustee's office directly at 865-457-6233 before making an offer on any Anderson County property. Ask for the current adopted rate for fiscal year 2025-2026 and confirm whether the specific parcel falls inside any city limits (Clinton, Norris, Oak Ridge, Oliver Springs, and Rocky Top all carry additional municipal rates on top of the county rate). A property inside the city limits of Oak Ridge, for example, carries both the county rate and a substantial city rate — the combined burden can be significantly higher than the county-only rate alone.

Campbell County: The Best Tax Story on the Lake

Campbell County holds the largest share of Norris Lake's total shoreline and contains the lake's mid-section and the Powell River arm. The county's fiscal year 2025-2026 combined property tax rate of $1.2156 per $100 assessed value was confirmed by the Campbell County Commission on June 26, 2025, with a 12-0 vote adopting the FY25-26 budget. The rate breaks down as county general ($0.6702), solid waste ($0.1195), ambulance service ($0.0676), industrial/economic development ($0.0151), highway/public works ($0.0470), general purpose school ($0.2135), general debt service ($0.0310), and general capital projects ($0.0517).

For a $500,000 lakefront in unincorporated Campbell County — typical for a three-bedroom dock-included property on the Powell River arm — the annual county property tax is approximately $1,519. That is among the lowest annual property tax burdens on any T1 lake market in the Southeast. The caveats: properties within the city limits of La Follette add a city rate on top ($1.29 per $100), and properties in Jellico add even more. The vast majority of Norris Lake waterfront in Campbell County is unincorporated, but verify the specific address with the Campbell County Assessor (423-562-9446) to confirm no city levy applies.

Union County and Claiborne County

Union County at $1.79 per $100 represents a middle ground — lower than most TN lake counties, higher than Campbell. Union County properties on Norris typically sit in the eastern arms and southeastern reaches of the lake. The trade-off for the lower rate is distance: Union County lakefront generally requires a 45-55 minute drive to Knoxville for daily needs, versus 25-35 minutes from Anderson County and 30-45 minutes from much of Campbell County. For buyers who work remotely or are fully retired, this trade-off often makes sense. For buyers who need regular Knoxville access, the commute math changes the calculus.

Claiborne County at $2.48 per $100 is the highest rate among the primary Norris counties, and Claiborne County sits farthest from Knoxville — with Tazewell and New Tazewell serving as the nearest commercial centers rather than Knoxville itself. That distance is reflected in lower home prices, which partially offsets the higher rate. A $400,000 Claiborne County lakefront carries approximately $2,480 per year in property taxes — still lower in absolute dollar terms than many comparable lake markets in the Midwest or Northeast, even at the higher rate.

Tennessee Senior Tax Relief Programs

Tennessee operates a state-funded property tax relief program for qualified elderly, disabled, and disabled-veteran homeowners. For homeowners 65 and older who meet the income threshold, the state reimburses a portion of the property tax bill directly to the county — meaning the homeowner's net tax burden can be substantially lower than the nominal rate suggests. Income limits adjust periodically; as of 2025-2026, the program applies to homeowners with total household income at or below $37,780 annually. The maximum reimbursement amount also varies by county and is set by the state annually.

To apply, contact the trustee in the county where the property is located. Anderson County Trustee: 865-457-6233. Campbell County Trustee: 423-562-3505. Union County Trustee: 865-992-8211. Claiborne County Trustee: 423-626-3275. Applications are typically due by April 5 for the prior year's taxes, though extensions are available for qualifying circumstances. If you are 65 or older and buying on Norris Lake as a primary residence, this program should be part of your total cost analysis from day one.

What the County Line Means at Closing

The Norris Lake shoreline crosses county lines in dozens of places. Some peninsulas have properties in different counties on either side. Some cove communities sit entirely in one county. County lines do not always correspond to visible landmarks on the water — two adjacent lots can be in different counties with materially different tax bills. The county of record is established in the deed and on the parcel record; it is not something you can determine by looking at a map of the shoreline. Before making any offer, confirm the county with the title company or by pulling the parcel record from the relevant county assessor.

For buyers comparing two lakefront options with similar list prices, county location should be a deliberate part of the analysis. A $200 per month difference in property taxes is $2,400 per year and $24,000 over ten years. That kind of difference compounds meaningfully over a typical hold period. A specialist who works the Norris Lake market routinely can tell you which coves and peninsulas fall in which county — another reason a local buyer's agent with Norris Lake experience is worth engaging early, before you fall in love with a specific property without knowing the tax picture.
