Assessor's Office

Any questions with a tax bill, please contact the Revenue Collector's Office at 860-465-3029.

Windham is performing a revaluation for the Grand List of October 1, 2023.  This revaluation will impact the tax bills due beginning in July 2024.  The Town of Windham 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, and using the prior mill rate will not correctly calculate your July 2024 tax bill.  The new mill rate will be determined by the Board of Finance with the adoption of the 2024/2025 budget.

If you are a Windham property owner, and you do not have your 2023 revaluation assessment notice, you may look up the new assessment for your property using this online database. 

In conjunction with the 2023 revaluation assessment notices, you may review your new assessment with a representative of Vision Government Solutions by scheduling an informal hearing. Informal hearings will be held by appointment only.  

To schedule an informal hearing, you may go to and follow the instructions to schedule an informal hearing.  You will need the Parcel ID number (PID#), which can be found at the top of the 2023 revaluation assessment notice or on the online database.  If you wish to schedule an informal hearing for two or more properties, please do not schedule your hearings online, please call Vision Government Solutions at 1-888-844-4300.   If you do not have access to a computer, or prefer to call for an appointment time instead of scheduling your informal hearing online, you may call 1-888-844-4300 between the hours of 9:00 AM and 4:00 PM, Monday through Friday, excluding state holidays. 

Please DO NOT contact the Town of Windham Office of Assessment to schedule your informal hearing with Vision Government Solutions.  The Town’s staff does not have access to create, change, or cancel hearing appointments. 

If you wish to appeal your assessment after the informal hearing, or if you are not able to attend an informal hearing, you may file an appeal with the Town of Windham’s Board of Assessment Appeals. Appeals to the Board of Assessment Appeals must be filed on or before February 20, 2024. You do not have to attend an informal hearing to apply for a hearing with the Board of Assessment Appeals, but please bear in mind that the Board of Assessment Appeals process is more involved and more formal. You may obtain an appeal application at the Town of Windham website located at

Office Purpose & Function

The purpose of the Assessor's office is to discover, list, value, and defend in court, all real estate (7,000 parcels), business personal property (900+ accounts), and motor vehicles (Supplemental and Regular Grand Lists totaling over 19,000 accounts) in a uniform, equitable manner, conforming to State and Federal standards and mandates.

The established tax base provides for approximately one-half of the total Town budget; payments in lieu of taxes (PILOT) provide for additional funding. PILOT fund applications are provided largely by the Assessor's office, i.e. values generated and reported for properties owned by the State, Housing Authority, private colleges and hospitals, manufacturing facilities, as well as elderly, veterans and disabled homeowners.

The Assessor's office conducts monthly sales ratio analysis reports for the State Office of Policy and Management, while maintaining and updating ownership and mapping records. Assessment information and technical assistance are provided to property owners, attorneys, developers, realtors, other departments and the Board of Assessment Appeals on a frequent and regular basis.

Additionally, this office administers several exemption/or tax relief programs, including Elderly/Totally Disabled Homeowners; Veterans and Active Duty Service members; Blind and Totally Disabled property owners; "Freight for Hire" motor vehicles; Farm and Forest Land classifications; Farming Equipment exemptions; Ambulatory Motor Vehicle exemptions; Newly Acquired Manufacturing Equipment; Manufacturing Facility exemptions; Enterprise and Entertainment District exemptions.

This office also conducts revaluation projects in accordance with statutory standards and schedules, largely in-house, as opposed to a full contract with a vendor, at very significant savings to the Town.

Inspection Program

State law now requires revaluations to be conducted every five years, which must comply with CT Standard Performance Regulations and meet several statistical tests of compliance. A ten-year plan of inspections is continually conducted, so that an inventory of the bulk of Town properties will have been physically listed by the next revaluation.

Field personnel carry identification and have been registered with the Local Police Department.

Elderly & Disabled Homeowners

Tax payers who are 65 years of age or older or retired from regular gainful employment by reason of disability or a veteran of the armed forces of the United States entitled to and receiving compensation from the United States Department of Veteran Affairs at a total disability rating for a service-connected disability. Applicant who fit the requirements may receive a reduction on the amount of property taxes due. The reduction will be based on the applicant's income, the value of the residence and the local levy rates.

Business Personal Property

Property owned by a business which is movable and not affixed or associated with the land. Personal property would include: inventory, furniture, cars/trucks, etc. that was purchased and used by a business that is not classified as real property. The filing requirements for business personal property must be filed every year by November 1st.

Motor Vehicles

Motor vehicles are subject to a local property tax under Connecticut State law. Assessments are based upon 70% of the average retail value which is determined by your local assessor. Supplemental motor vehicles are defined as vehicles which are registered "between October 2nd and July 31st". Taxes are prorated from the month the motor vehicle has been registered through September at the following percentages of assessed value.
