Property Tax Guide for Prospect, CT

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

Overview

Prospect's current mill rate is 25.57 mills for the 2024 Grand List (FY 2025–2026). Real estate and personal property taxes over $100 are payable in two installments, with a four-installment option available for qualifying real estate. The town sends reminder notices for unpaid second installments in January, but you should not rely on receiving one.

Important: Prospect does not mail a separate second-installment bill. Your July bill includes payment stubs for both installments. The town sends reminder notices the third week of January for unpaid second installments, but failure to receive one does not excuse late payment. Missing the deadline triggers 1.5% monthly interest.
