Real Estate, Personal Property & Motor Vehicle Tax Bills

  • Supplemental Motor Vehicle tax bills, which are issued for any vehicles newly registered between October 2 and July 31 and are due and payable on January 1 – with February 1 being the last day to pay without penalty.

State Statutes & Delinquent Tax Bills

  • The Lyme Tax office is governed by Connecticut General Statutes. Two of the most important of these state that:
    • a resident’s failure to receive a tax bill or the Tax Office’s failure to send a tax bill does not invalidate a tax; and
    • a Tax Collector does not have the authority to waive interest on a delinquent tax.
  • Under state statute, delinquent tax bills are charged interest at the rate of 1.5% per month (18% per year) from the original due date of the tax bill – with a minimum penalty of $2.00 per delinquent tax bill.
