The Assessor's office is primarily responsible for preparing the Town's Grand List. The Grand List is generated each year in January or February and is a record of all taxable and tax-exempt property as of Oct 1st. Taxable property includes real estate and personal property, including motor vehicles. The office is also responsible for maintaining the assessor maps and data about all properties, and for applying tax exemptions or reduction programs such as the veterans, disabled, elderly, blind, and PA 490 programs. Please call or email the Assessor for information about these programs.
Please email or call to make arrangements in advance if you require access to the assessor's records or an appointment for a tax reduction program application.

For boundary line or acreage issues, please refer to this document for our policy and procedures to remedy discrepancies: Policy on boundary and acreage discrepancies
Additional mapping data is available through the Northeast Council of Governments site: GIS | Online Mapping | Northeastern CT | NECCOG and is updated to correspond to Canterbury parcel data periodically.
The parcel data available online does include Survey Map numbers from the Town Clerk's office when a survey has been filed for that parcel. Please refer to these numbers when requesting survey maps from the Town Clerk.

Public Act 24-46, An Act Establishing a Property Tax Exemption for Veterans Who Have a Service-Connected Permanent and Total Disability Rating took effect October 1, 2024 impacting the real estate bills issued in July 2025.
The CT legislature made changes to the law in the Spring of 2025 in an effort to provide clarification. The impact of those changes were finalized with the 2024 Grand List. Any additional changes to eligibility requirements or provisions of the law will impact upcoming Grand List years via local ordinance upon town approval. Widowed spouses may now be considered eligible for the 2025 Grand List - please contact the Assessor for qualification requirements.
If you feel you may be eligible for an upcoming tax year, please be sure your DD214 is on file with the Town Clerk and your most recent Disability Rating letter from the VA is filed with the Assessor as soon as possible.
There is an annual application required which you will find by clicking the link below. The deadline to file annually is Jan 1st but due to the holiday, it is advised you file on or before the workday prior to New Year's Eve to be sure your application is on time.
