Due dates, payment options, and what Durham residents need to know to avoid late fees
Overview
Durham's current mill rate is 37.39 mills for real estate and personal property, and 32.46 mills for motor vehicles (2024 Grand List / FY 2025–2026). Property taxes are due in two installments, and the town does not mail a second-installment bill.
Important: Durham does not mail a second-installment bill. If you paid your first installment in July, your second payment is still due January 1 — even if you don't receive a bill. Missing this deadline by even one day triggers 3% interest (covering both January and February).
