Middletown, CT Property Tax: Due Dates, Mill Rate, Payment Options & Deadlines

Due dates, payment options, and what Middletown residents need to know to avoid late fees

Overview

Middletown's base city mill rate is 31.70 mills for the 2024 Grand List (FY 2025–2026), but your total rate depends on which fire district you're in. Taxes are due in two installments for bills over $100, and the city follows standard Connecticut practices for late payment interest.

Important: Middletown does not typically mail a second-installment bill. Your second payment is due January 1 — even if you don't receive a reminder. Missing this deadline triggers 1.5% monthly interest (18% annually) backdated to the original due date.

Mill Rate & What You'll Pay

Current mill rates (2024 Grand List / FY 2025–2026):

District	RE/PP Mill Rate	MV Mill Rate
City Fire District	38.90 (city 31.70 + fire 7.20)	32.46
South Fire District	37.011 (city 31.70 + fire 5.311)	31.70
Westfield Fire District	33.687 (city 31.70 + fire 1.987)	31.70

The maximum combined motor vehicle mill rate is 32.46 per CT General Statutes §12-71e.

A home assessed at $200,000 in the City Fire District would owe approximately $7,780 per year.
