Welcome to the Town of South Windsor’s Assessor website! We hope you find it a useful resource for practical information about property values and the assessment process. Field card data and maps are also easily accessible.

The Assessor’s Office is responsible for discovering, listing, and valuing all real property, business personal property, and motor vehicles located within the Town of South Windsor as of October 1 of each year in accordance with Connecticut State Statutes. We also administer various state and local benefit programs for our Elderly and Disabled Homeowners, as well as our Veterans and Legally Blind residents. Feel free to browse through our links for more information.

The Assessor’s primary duty is to determine the value of all taxable and tax exempt Real and Personal Property for the purpose of equitable tax distribution throughout the Town of South Windsor. Real property is assessed at 70% of a base year of value established on the October 1, 2017 revaluation. Personal Property and Motor Vehicles are also assessed at 70% annually.

Our objectives are to provide South Windsor taxpayers with courteous and responsive service, and to maintain an equalized tax base according to State Statutes and professional standards.
