Connecticut Real Estate Tax Authority Guide

Connecticut’s real estate tax structure is one of the most localized and complex in the United States, defined by a decentralized framework where carrying costs and closing liabilities differ sharply across its 169 independent municipalities. Rather than a uniform county or state-level property tax, residential carrying costs are determined by applying individual municipal mill rates to a statutory assessment ratio of exactly 70% of fair market value, revalued on a strict five-year cycle. On the transaction side, sellers must navigate a multi-tiered State Real Estate Conveyance Tax alongside local transfer fees and federal capital gains implications. This comprehensive Connecticut Real Estate Tax Authority Guide provides buyers, homeowners, and sellers with the statutory formulas, localized rate mechanics, municipal tax collector contacts, and vetted professional resources needed to accurately forecast property liabilities and safeguard financial equity.
