What the site does
The homepage calculator compares two or three Connecticut towns on one fair-market-value price. Each town page shows that town’s FY2026 municipal mill rate, effective rate, example taxes at several prices, and a quick compare against nearby towns. Fairfield County compare pages fix a $1.6M house so the spread between a pair is easy to read.
Supporting pages explain how CT property tax works, summarize the FY2026 mill-rate dataset, and outline a high-level assessment appeal path. None of those pages replace the assessor, tax collector, or a licensed professional.
Data source (FY2026)
Municipal real-property and motor-vehicle mill rates come from the Connecticut Office of Policy and Management’s published mill-rate tables for fiscal year 2026 (grand list dated October 1, 2024). The public OPM mill-rate page is here: CT OPM mill rates. This site filters to the 169 primary municipalities and applies the statutory formula:
annual tax = (price × 0.70 × mill rate) ÷ 1,000
Fire-district and other special-district mills are not merged into the municipal rate on this site. Motor-vehicle rates are available via a separate toggle and are subject to the statewide cap of 32.46 mills.
