Melton Hill Lake Property Tax by County

Why Oak Ridge Alone Has Two Different Rates

Oak Ridge is unusual among Tennessee cities in that it sits inside two separate counties at once: Anderson and Roane. Roughly 16% of the city's taxable real parcels fall within the Roane County section, with the remainder in Anderson County. Because Tennessee property tax rates are set at the county level and then blended with any municipal levy, a single city government in Oak Ridge effectively operates under two different combined tax rates simultaneously, depending purely on which county a given parcel's underlying land falls in. Both the Anderson County and Roane County sections of Oak Ridge were reappraised in fiscal years 2016 and 2021, according to the city's own tax rate documentation, and Anderson County underwent a further reappraisal effective for the 2025 tax year specifically.

The Current Rates, Side by Side

Following Anderson County's 2025 reappraisal, the county commission approved combined rates for fiscal year 2026 of $1.4065 per $100 of assessed value for the Oak Ridge, Anderson County section; $1.4889 per $100 inside the city of Clinton; and $1.5037 per $100 for Oliver Springs, Rocky Top, Norris, and the remaining unincorporated rural areas of the county. The Roane County section of Oak Ridge, by contrast, carries a combined rate of $2.4526 per $100 of assessed value, according to the Oak Ridge Economic Development Initiative's published property tax figures. This is a substantial gap: $2.4526 versus $1.4065 per $100 is nearly 75% higher in the Roane County section of the same city.

Tennessee assesses residential property at 25% of appraised market value, with the county rate applied to that assessed figure. A $500,000 home in the Anderson County section of Oak Ridge, assessed at $125,000, would owe roughly $1,758 per year at the combined rate of $1.4065 per $100. The identical home, if it happened to sit in the Roane County section instead, would owe roughly $3,066 per year at $2.4526 per $100 — a difference of over $1,300 annually on a mid-priced home, growing proportionally larger as home values rise.

Confirming Which County a Parcel Sits In

Because the county line running through Oak Ridge is not always obvious from a street address or a listing photo, any buyer seriously considering a specific property should confirm directly with the Anderson County or Roane County Assessor's office which jurisdiction applies before making an offer, rather than assuming based on the general area of the city. This is a five-minute phone call that can identify a four-figure annual difference in carrying cost, and it is the single most important tax-related due diligence step specific to buying in Oak Ridge on this lake.

Loudon and Knox County Rates

The Lenoir City side of Melton Hill Lake sits in Loudon County, which is regionally regarded as carrying a moderate tax burden relative to Knox County's more urban core, while the small Knox County stretch near Hardin Valley falls under one of the lower effective property tax rates among Tennessee's more populous counties. Buyers considering either area should request current millage figures directly from the respective county trustee's office, since Anderson and Roane County, where the bulk of this lake's Oak Ridge-adjacent shoreline sits, were the primary focus of the rate research on this page.

For context, Knox County's effective property tax rate runs among the lower rates of Tennessee's populous counties, well below the combined rate in Oak Ridge's Roane County section discussed above. A buyer specifically prioritizing lower ongoing property tax above all other considerations, and willing to accept the tradeoffs of the Hardin Valley area discussed on this site's neighborhoods page, may find the Knox County stretch of this lake the most tax-efficient option among the four counties covered here, though this should always be confirmed against a specific parcel's actual current bill rather than a general county-level average.

Reappraisal Cycles Worth Tracking

Anderson County operates on a five-year reappraisal cycle, with 2025 marking its most recent reappraisal and the next one due five years later. Buyers holding property through a future reappraisal cycle should expect another rate reset at that time, following the same revenue-neutral recertification process described above, and should not assume the current $1.4065, $1.4889, or $1.5037 figures will remain fixed indefinitely.

Roane County follows its own separate reappraisal schedule, distinct from Anderson County's cycle, meaning the two sections of Oak Ridge will not necessarily reappraise in the same year going forward. This can, over time, either widen or narrow the current gap between the two sections' rates, and buyers holding property for the long term should treat both counties' reappraisal calendars as a factor worth tracking rather than a fixed, one-time consideration handled entirely at the point of purchase.

Homestead and Senior Relief

Tennessee offers standard statewide property tax relief for qualifying elderly, disabled, and disabled veteran homeowners, administered through each county trustee's office rather than through the state directly. Anderson, Roane, Loudon, and Knox counties all participate in these standard state programs, though income eligibility thresholds and application deadlines are set at the state level and should be confirmed directly with the relevant county trustee for any buyer who expects to qualify, since the process and paperwork are handled at the county level even though the underlying program is statewide.

Buyers should also ask each county assessor directly about any active appeal or reassessment process affecting a specific property, since Anderson County's 2025 reappraisal, discussed above, generated a documented wave of appeals activity, particularly among commercial and industrial property owners, though residential owners retain the same appeal rights through the county Board of Equalization if they believe a specific assessment is inaccurate.

Given the genuine complexity of Melton Hill Lake's four-county tax picture, buyers are well served by requesting a written, itemized current tax bill for any specific property under serious consideration, rather than relying on a general county-level rate. This is a standard request any seller or listing agent should be able to fulfill quickly, and it removes any ambiguity about which combination of county and municipal rates actually applies.

The overarching lesson for this lake's tax picture is simple: never assume, always confirm in writing, and treat the county line running through Oak Ridge as seriously as any other major factor in a purchase decision.
