Supplemental Motor Vehicle Taxes

The Tax Collector is reminding taxpayers that supplemental motor vehicle taxes on the Grand List of October 1, 2017 are due in full January 1, 2019 and payable by February 1, 2019.  Unpaid taxes will be considered delinquent on February 2, 2019.  On that date interest will be charged from the original due date of January 1, 2019.  Interest is charged at a rate of 18% per year, with a minimum of $2.00, in accordance with the provisions of C.G.S. Sec. 12-146.

Supplemental motor vehicle tax bills are scheduled to be mailed on Monday, December 17, 2018.  Failure to receive a tax bill does not invalidate the tax or any interest on it should it become delinquent.  Taxpayers who do not receive their tax bill should contact the office at 860-285-1810 to obtain a copy.

Supplemental motor vehicle bills are for any newly registered vehicle after October 1, 2017.  Vehicles are assessed based on the month they were first registered through September 30, 2018.  If this vehicle replaces a vehicle on the regular October 1st Grand List, a credit for that vehicle will show on this bill.  If this vehicle has been sold, destroyed, stolen or registered in another state, please contact the Assessor’s Office.

If you have moved out of state, please pay your bill and provide a copy of your new registration to the Assessor’s office, or call 860-285-1817, or fax the copy to 860-285-1820.

If you have moved out of town but still live in the state, the bill is still due.  Please notify the town of your new address and also notify the state Department of Motor Vehicles’ registration office.

Cash, certified bank check, money order, or credit card will be required when paying past-due motor vehicle taxes.  Personal checks will not be accepted if a DMV clearance is needed for motor vehicle registration.  All motor vehicle taxes, including the new supplemental motor vehicle taxes, must be paid in full in order to receive a DMV clearance, regardless of whether the bills have been mailed as of yet.

Taxpayers also have the option of paying by credit card either online through the Town of Windsor website at or directly at or by calling 1-800-272-9829 using Jurisdiction Code 1771.  PLEASE NOTE:  CREDIT AND DEBIT CARDS ARE ALSO ACCEPTED AT THE TAX OFFICE for a convenience fee.  Payment of delinquent taxes must be paid directly to the Town of Windsor, Tax Office, 275 Broad St., Windsor, CT  06095.  If anyone receives a tax bill that says, “Back Taxes Due”, please contact the tax office for the total amount due.

Payments may be made by mail or in person at the Tax Collector’s office, located on the first floor of the Town Hall.  Office hours are Monday through Friday, from 8:00 a.m. to 5:00 p.m.  There is a drop-off box located in the center section of the Town Hall parking lot which is available year-round.  All payments should be accompanied by a bill.  Taxpayers, who wish to receive a paid receipt, must return the entire bill with a stamped, self-addressed envelope along with their payment.
