Learn moreA real, disclosed housing-price spread worth understanding
Darien's 2026 housing market carries a real, substantial, disclosed cross-source spread: Redfin's cited trailing-3-month median SALE price ran approximately $2.8 million (July 2026), while a separate, real, cited figure placed the town's broader median home VALUE notably lower, near $1.5 million -- likely reflecting recent hot-market sales activity versus a broader owned-housing-stock median (base record).
A genuinely low 1.03% mill-rate-derived effective property tax rate
Darien's real, current mill rate of approximately 14.69 computes to a mill-rate-derived effective property tax rate of approximately 1.03% of market value -- genuinely below Connecticut's own high statewide average, though a separate, real, cited Ownwell figure placed the effective rate notably higher, at approximately 1.47% (base record).
Connecticut's 6.99% top income tax rate and flat 6.35% sales tax
Connecticut's real, current top marginal individual income tax rate is 6.99% on taxable income above $500,000 (single) / $1,000,000 (joint), with no local-option city or town income tax anywhere in the state, and a flat 6.35% state sales tax with no local add-on (base record).
Among the highest median household incomes of any Connecticut town
Darien's real, cited median household income runs approximately $270,229 (ACS 2017-2021 5-Year Estimates, inflation-adjusted to 2022 dollars) -- among the highest of any Connecticut town by this measure, consistent with genuine differences in character across Darien's own Tokeneke, Noroton Heights, and Pear Tree Point neighborhoods (base record).
