Welcome to the Town of Stonington, Connecticut, Assessor’s Online Assessment Database.

This database provides you with information on each residential parcel of real estate in Stonington, along with the ability to search for sales of properties that might be similar to your selected property. 

Stonington is performing a revaluation for the Grand List of October 1, 2022.  This revaluation will impact the tax bills due beginning in July 2023.  The Town of Stonington and Vision Government Solutions are working on this revaluation at this time.

Do not apply the current tax (mill) rate to your new assessment, as the mill rate will change. Using the prior mill rate will not estimate your July 2023 tax bill.  The Town will set a new mill rate in Spring 2023. 

If you wish to appeal your assessment after the informal hearing process is complete, you must file a written appeal to the Stonington Board of Assessment Appeals on or before March 20, 2023.
