Municipal Tax Relief Deferral Program Information:

1/5/2021 - Municipal Tax Relief Deferral Program


On April 20, 2020 the City’s Board of Aldermen elected to implement a Deferment Program as set forth in the Governor’s Executive Order7S, §6, allowing eligible City residents, businesses and landlords an extended grace period to defer the interest on their payment of property taxes, and water & sewer user fees until 90 days from the initial due date, instead of the usual 30 days. As set forth in Governor’s Executive Order 9R signed on December 16, 2020, the City will implement the same Deferment Program applied to the tax deadlines and collection efforts for tax bills that become due and payable on January 1, 2021. Deferment is not automatic. You must submit an Application to the Tax Department by February 1st, 2021 and be deemed eligible. Please note: If you previously applied and were approved for the July 2020 Deferral Program, you do not need to reapply for the January 2021 Deferral Program. Real estate escrow agents and leasing companies are ineligible for the Deferment Program. Said election shall apply to any property tax, water and/or sewer charge that becomes due and payable on January 1st, 2021.

New applications MUST be received by the Tax Office by February 1st, 2021.
Late applications cannot be considered.

Eligible Resident:
Household has suffered a reduction in income of at least 20% due to COVID 19.

Eligible Business / Non-Profit:

Eligible Landlords:

Please note that interest will accrue back to the initial due date at 1.5% per month on any unpaid balance as of the end of the 90 day grace period

Failure to receive a tax bill does not invalidate the tax or interest due. As owners of property, taxpayers are responsible to know when their taxes are due. Failure to have received a bill does not exempt the taxpayer from payment of all taxes and all interest charges and collection cost, per Conn. Gen. Stat. 12-130 and 12- 146. Interest is charged to all late payments. There are no exceptions to this policy.

Tax Bills are mailed in Late June (for October 1st Grand List) and Late December (for Supplemental Grand List), installment due dates of July 1st and January 1st. Taxes must be paid within a month of the due date; if not, there is an interest charge of 1.5 % per month (18 % annually), from the due date with a minimum interest charge of $ 2.00 per bill.

Real Estate Taxes: 1st half due July 1st each year, 2nd half due January 1 each year. No bill will be sent for 2nd installment.

Motor Vehicle & Personal Property Taxes: First half due July 1st each year, second half due January 1st each year. No bill will be sent for the second installment.

Supplemental Motor Vehicle Taxes: Due January 1 each year for vehicles registered after that years' assessment date October 1st & before July 31st.
