Notice Regarding July 2018 Tax Prepayments

As a consequence of recent changes in the way state and local property taxes may be allowable as deductions in the federal tax code, taxpayers have approached Town officials about ‘prepaying’ taxes during calendar year 2017 for tax obligations that will come due in calendar year 2018 or beyond.


The state statutes in Connecticut relative to taxation are strictly interpreted, meaning, unless the authority is specifically granted it CANNOT be assumed that such authority exists.  The town cannot infer powers and cannot ‘read into’ the statutes to find authorities that are not there.


Tax collectors have authority to collect when they have been issued a tax warrant and a rate bill.  Unless and until they have these documents, they have no authority to collect.  That means tax collectors do not have the authority to collect ‘prepayments’ of taxes that will come due in July 2018 and beyond. 


The Town of Windsor bills in one annual installment which was due in July 2017.  Some towns bill in more than one installment and therefore they have the authority to collect the January 1, 2018 installment during December 2017.   Taxpayers in those towns are welcome to make those payments now.  By law, that entire tax came due on July 1, 2017, and the installments are merely a convenience for the taxpayer.  (Some towns, such as Westport, bill quarterly, and are accepting January 2018 and April 2018 installment payments for that reason.) 


Town and City officials have performed due diligence and consulted with the Connecticut Tax Collectors’ Association, the Connecticut Association of Municipal Attorneys, the Government Finance Officers’ Association,  Connecticut Tax Collectors’ Association Certification program instructors, and other public officials with knowledge of state law.  The Connecticut Tax Collectors’ Association has an opinion from its corporation counsel advising that there is no state statute that exists which authorizes tax collectors to accept prepayment of July 2018 tax installments at this time, and that doing so would conflict with state law.  This opinion further advised that municipalities need to evaluate the risk of accepting such prepayments when doing so could be considered an effort to evade federal income tax liability.  Accordingly, accepting these prepayments is not only contrary to state law and improper not only from a tax collecting perspective, but also contrary to generally accepted cash management and internal control procedures.


For these reasons, the Town of Windsor Tax Collector’s Office will not be accepting ‘prepayments’ toward July 2018 and future tax installments until a rate bill is signed after the referendum in May 2018.


Notice - Town of Windsor Taxpayers

The Tax Collector is reminding taxpayers that supplemental motor vehicle taxes on the Grand List of October 1, 2016 are due in full January 1, 2018 and payable by February 1, 2018.  Unpaid taxes will be considered delinquent on February 2, 2018.  On that date interest will be charged from the original due date of January 1, 2018.  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 18, 2017.  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, 2016.  Vehicles are assessed based on the month they were first registered through September 30, 2017.  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, or money order 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.  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.
