Equalized tax rate — all 169 towns
Every town's total tax levy per $1,000 of the market value of all its taxable property, for —. Sorted lowest to highest; rank 1 is the lowest rate, which is a description of the rate, not a grade of the town. Bars are shaded by quarter of the ranking.
Source: computed as total tax levy (CT OPM he33-brru) divided by the equalized net grand list (CT OPM 8rr8-a322), both from data.ct.gov; payload ct_equalized_rates.json, which lists every screened or substituted levy cell in its metadata. This levy-based rate runs about 1% above OPM's own published equalized rate (which divides collections, not billings); every town gets the same method in the same year.
Posted (nominal) mill rate — all 169 towns
The rate each town actually posts for —, ranked the same way. This ordering mixes tax decisions with revaluation timing — it is shown because it is the number residents see on their bills, not because it compares towns fairly. The tooltip shows each town's equalized rank beside its nominal rank; a large gap between the two usually means the town is early or late in its revaluation cycle.
Source: CT OPM Mill Rates (emyx-j53e) via ct_mill_rates.json. Real-estate/personal-property rate; the motor-vehicle rate is capped by statute and differs in towns above the cap.
The full table
All 169 towns with both rates. “Nominal ÷ equalized” is a rough staleness signal: the higher it is, the further the town's assessments sit below current market value.
How this ranking is made
Equalized rate = (total tax levy for the fiscal year) ÷ (equalized net grand list) × 1,000. The equalized net grand list is OPM's estimate of the market value of all taxable property in the town, built from actual sales ratios by property class. The levy for a fiscal year is laid against the grand list dated October 1 two years earlier; the mapping was verified against OPM's audited indicators file, where it matches exactly.
What it is not: this divides billings, where OPM's own published equalized mill rate (audited series, ending FY 2022-23) divides collections — the two differ by roughly each town's collection rate, about 1% for most towns. A handful of consolidated cities file only part of their levy in the state's levy file; those cells were substituted from the adopted-budget summary and each substitution is listed, town by town, in the payload's metadata.
Direction: rank 1 is the lowest rate throughout this page. That is a sort order, not a verdict — a low rate can reflect a large tax base, heavy state aid, low service levels, or low costs, and this page does not distinguish among them.
