Conn. Gen. Stat. § 12-494 (State Real Estate Conveyance Tax)

Connecticut Real Estate Conveyance Tax Calculator

Compute the two-layer Connecticut transfer-tax stack — the State Real Estate Conveyance Tax under Conn. Gen. Stat. § 12-494 (true progressive/marginal tiers on residential at 0.75% / 1.25% / 2.25%, flat 1.25% commercial, flat 0.75% unimproved land) plus the Municipal Real Estate Conveyance Tax under § 12-639 (0.25% standard, 0.50% in the eighteen designated 'target community' municipalities under § 12-639(b)). Isolates the PA 19-186 mansion-tier portion (the 2.25% rate on dollars above $2.5M) so sellers above the Gold Coast threshold can see exactly how much of their bill is attributable to the 2020 add. Unlike New Jersey's tier-based-flat structure, Connecticut's state residential tax is genuinely marginal.
