Property tax in Sullivan County: county, state and US

Census ACS 2020–2024 estimates for owner-occupied homes. The median annual tax paid is a historical survey estimate, not a quote for this year’s bill.

AreaMedian annual tax paidMedian home valueEffective rate estimate
Sullivan County$5,756$268,7002.14%
New Hampshire$6,667$402,5001.66%
United States$3,119$332,7000.94%

Sullivan County’s effective-rate point estimate is 0.49 percentage points above New Hampshire’s and 1.20 percentage points above the US estimate.

Effective rate = median annual real estate taxes paid (B25103) ÷ median owner-occupied home value (B25077). State and US figures use their own Census medians, not averages of counties. These ratios are not statutory rates or medians of individual tax rates. Differences are not tests of statistical significance. Bounded or missing estimates stay unavailable.
