Property Tax on Kentucky Lake — Tennessee Side

Tennessee Has No State Income Tax

This is the most important tax fact for any Kentucky Lake buyer comparing the Tennessee and Kentucky sides of the lake. Tennessee has zero state income tax on any form of income — no tax on Social Security, pension distributions, 401(k) withdrawals, IRA income, investment dividends, or capital gains distributions. The state repealed its Hall Income Tax on dividends and interest effective January 1, 2021. Kentucky imposes a flat 4% income tax rate on most income including retirement distributions. At $120,000 in annual retirement income, the difference is $4,800 per year in state income tax — Tennessee pays zero, Kentucky pays $4,800. Over a 20-year retirement, that gap exceeds $96,000 in cumulative state income tax savings on the Tennessee side. No property tax rate comparison between the two states approaches this difference in magnitude for income-drawing retirees.

Benton County — Paris Landing Area

Benton County is the primary Tennessee-side county for Kentucky Lake real estate, anchored by Paris Landing State Park and its marina, inn, and golf course. The Benton County property tax rate should be verified with the Benton County Trustee before closing — verify at the Benton County Courthouse in Camden, Tennessee. Tennessee assesses residential property at 25% of appraised market value statewide, so the effective tax rate is one-quarter of the per-$100 statutory rate applied to market value. On a $500,000 home in Benton County: assessed value is $125,000 (25% of $500,000). Divide by 100 to get 1,250. Multiply by the applicable county rate to get the annual tax bill. Benton County historically has carried effective tax rates well below the national median — confirm the current rate before purchase.

Henry County — Paris, Tennessee

Henry County borders Benton County to the east and includes the city of Paris, Tennessee — the largest town in the immediate Kentucky Lake Tennessee-side area, with approximately 10,000 residents, a hospital (Henry County Medical Center), and the commercial services base for the surrounding lake community. Paris Landing State Park is technically in Benton County but is accessible from both counties. Henry County property tax rates are set by the Henry County Commission annually. Verify the current rate with the Henry County Trustee in Paris, Tennessee before making purchase decisions that depend on specific tax estimates. Both Benton and Henry counties offer the Tennessee structural advantage — no state income tax — regardless of which county a specific property is in.

Stewart County and Other Tennessee Counties

Kentucky Lake on the Tennessee side runs through 11 counties in total, though Benton and Henry are where the majority of buyer-market activity concentrates. Stewart County, south of Benton County along the lake, has a rural character with limited commercial services — the primary appeal is lower land prices and lake access farther from the Paris Landing tourism hub. Humphreys and Houston counties carry even smaller lake real estate markets. For most buyers evaluating the Tennessee side of Kentucky Lake, the county choice effectively comes down to Benton (Paris Landing proximity, strongest recreational infrastructure) versus Henry (Paris TN services, hospital, more urban amenity base). Confirm applicable county tax rates with the respective county trustees before closing on any property in any county.

The Senior Property Tax Relief Program

Tennessee's Property Tax Relief program applies to all Tennessee-side Kentucky Lake counties. Homeowners age 65 or older with household income of $37,530 or less annually qualify for state-paid tax relief on the first $30,000 of market value. Disabled veterans with 100% service-connected disability and surviving spouses of those killed in action qualify for relief on the first $175,000 without an income test. Apply through the applicable county trustee annually by April 5 to apply to that year's tax bill. Neither Benton nor Henry county is particularly large — the county trustee offices are accessible and process these applications routinely. For qualifying retirees, the relief program meaningfully reduces the property tax burden on the Tennessee side.

Tennessee vs Kentucky: The Full Tax Comparison

Buyers who are considering property on both sides of the state line should do the full tax comparison before deciding. Tennessee offers zero state income tax. Kentucky offers a 4% flat income tax on most income. Tennessee property tax rates in Benton and Henry counties, while needing per-county verification, are typically moderate rural county rates applied at 25% assessment. Kentucky assessment ratios and local tax rates vary by county but Kentucky does not have the same 25% residential assessment ratio Tennessee uses — Kentucky generally assesses at 100% of fair cash value, so comparing statutory rates between the two states requires accounting for the different assessment bases. For most retirees drawing significant income from retirement accounts and Social Security, the income tax difference makes Tennessee the financially superior choice regardless of how property tax rates compare in any specific year. Run the math for your specific income level, your specific property budget, and the confirmed current rates in the counties you are evaluating — then decide.
