Welcome to the Town of Groton, Connecticut

Pay or View Taxes Online

Oldest Obligation

Per Connecticut General Statute Sec. 12-144b, payments must first be applied to the taxpayer’s oldest outstanding obligation (by type of tax – real estate, personal property, or motor vehicle.)

DMV Clearances

Per Connecticut General Statute 14-33, if motor vehicle taxes are unpaid, you will not be able to newly register or renew any vehicle registration with the Connecticut Department of Motor Vehicles.  ALL outstanding vehicle taxes associated with your name and/or your registration marker number(s) must be paid in full in order for a release to be issued.

If you are making a payment online and a DMV release is required, payment must be made by debit or credit card.  Payments made by EFT check require a 10-business day hold.

DMV no longer takes paper clearances.  DMV will be electronically notified of your payment.  You should be cleared to register two business days after your payment (i.e., if your payment was made on Monday, you could register on Wednesday).  Please check first whether you have any compliance issues at ct.gov/dmv/online.  Once cleared, you may be able to renew online without the need to visit a DMV office.

Partial Payments

Partial payments can be made online.  Select the bill or bills you wish to pay and add them to the “shopping cart.”  During the checkout process, you will be allowed to change the amount of the payment from the full amount due to the amount you desire to pay.  Once you enter the amount you wish to pay, the service fee will also adjust.  You will have an opportunity to review the payment before proceeding.


You will receive an immediate receipt for your payment; however, due to processing time, it will take two to four business days for your payment to be reflected on the web site.
