Payment Methods

Checks returned by the bank are subject to a twenty dollar ($20.00) processing fee.

Taxpayers who have not received a bill should contact the Collector of Revenue's Office for a duplicate. Failure to receive a tax bill does not invalidate the tax or penalties should the account become delinquent.

Unpaid taxes will be considered delinquent after August 1st and February 1st. On that date interest will be charged from the original due date of July 1st and January 1st.  Sewer bills will be considered delinquent after November 1st.  Interest is calculated at 1.5% per month from the original due date with a minimum charge of $2.00 in accordance with the provisions of C.G.S. Sec. 12-146. 

Collection Enforcement

The goal of enforcement procedures is the maximization of revenue to the Town. Penalties, interest charges and legal fees are intended to deter delinquency.

Connecticut General Statutes dictate interest of 1.5% per month retroactive to the due date or 18% per annum charged on all delinquent bills. There is a $2.00 minimum interest charge.

By Statute, failure to receive a tax bill does not invalidate the tax or the interest (S. 12-130).

Liens are filed annually on all accounts having outstanding taxes. Liens remain in effect until all taxes, interest and fees are paid in full.
