Connecticut has one of the highest property tax burdens in the country. Its statewide average effective property tax rate (taxes paid as a % of home value) is commonly cited around 1.5%–2.0%, with SmartAsset putting it at 1.66% and other trackers citing figures from 1.54% up to 1.92-2.0%, depending on methodology (owner-occupied housing value vs. assessed value vs. county blend). This is roughly double the ~0.99% national average cited in most current sources (note: some 2026 trackers peg the U.S. average slightly lower, around 0.89%-0.91%). Connecticut consistently ranks among the top 3-5 highest-tax states nationally, behind states like New Jersey and Illinois. There is enormous local variation because all 169 municipalities set their own mill rate independently: the statewide average mill rate for FY2025-26 is roughly 28-32 mills, but this ranges from under 11 mills in wealthy Fairfield County towns (Greenwich, Darien, Westport, New Canaan, Wilton) to nearly 69 mills in Hartford, one of the highest municipal rates in the entire U.S. Properties are assessed at 70% of fair market value before the mill rate is applied, which is a key structural driver of the higher effective rates.
Example: Connecticut's statewide median annual property tax bill is approximately $6,570-$6,670 (figures cluster around $6,573-$6,666 depending on the source/year), the 3rd-highest median tax bill of any state in the U.S. This masks wide regional variation: median bills reach roughly $8,867 in Fairfield County (the state's highest-cost area, home to Greenwich/Stamford-area towns) versus about $4,594 in Windham County (a lower-cost, more rural area in eastern CT) — nearly a 2x difference within the same state.
Be skeptical of several SEO-style sites (e.g., propertytaxrates.org, appealdesk.com, askdoss.com, ambrogiopletter.com, countrytaxcalc.com, shahrozesparacha.com) that surfaced in search results with suspiciously precise but inconsistent rate/dollar figures and aggressive headlines like "Save $500-$2,000" for a homestead exemption that doesn't broadly exist yet — their numbers were cross-checked against authoritative sources (portal.ct.gov, cga.ct.gov, jud.ct.gov, SmartAsset, Tax Foundation) before being included here, and any unverifiable figures from those sites were excluded. Practical tip: because Connecticut's 169 municipalities each set independent mill rates on property assessed at 70% of fair market value, the single most impactful "rate" a CT homeowner should check is their own town's current mill rate (ranging roughly 11-69 mills) rather than relying on any statewide average.
