Hartford County, CT follows the Connecticut statutory schedule. This page shows that schedule, the county's own website, and the late penalty — the county can still set its own dates, so confirm before you pay.
| Instalment | Due date | Notes |
|---|---|---|
| Second installment | January 2, 2027 | Second installment in towns that bill semiannually. |
| First installment | July 2, 2027 | First installment under the July 1 statutory default; towns may bill annually, semiannually or quarterly. |
An installment unpaid after the first day of the following month is delinquent and bears 18% annual interest from its due date.
Towns mail rate bills for the July 1 installment, with the second half due January 1 where semiannual billing is used.
Not yet. Hartford County is on the queue: we publish a county's own published dates once they have been checked against the county website. Ask for it and it moves up. Until then, the Connecticut statutory schedule above is the reliable starting point.
