Town hall is open to masked visitors, and the Assessor's office is operating during normal business hours. Staff may be working in the field or remotely, so it is important for callers to leave messages. Walk-ins are welcome, but appointments are encouraged due to the nature of our work.

We are accessible best by email ( and ), and by phone 860-663-1765 Ext.506. 


In accordance with Connecticut General Statues §12-40, all persons liable to pay taxes on personal property as of October 1, 2021 are hereby notified that they must file a Declaration of Personal Property with the Assessor's Office no later than November 1, 2021 or be subject to an estimated assessment and the statutory twenty-five percent (25%) penalty.

The Assessor' Office, as a courtesy, mails Personal Property Declarations to anyone who (the office knows) is conducting business in the Town of Killingworth. Failure to receive a declaration does NOT nullify obligation to declare taxable personal property to the Assessor in the form and manner prescribed. If you have terminated, moved, or sold your business as of October 1, 2021, you must complete the Affidavit on the front page of the declaration and return it to the Assessor's office by November 1, 2021. Otherwise, the Assessor must assume that you still own taxable personal property and have only failed to declare it. Additional documentation, such as dissolution paperwork, may be required. If the business closed/moved/sold after October 1, 2021, you are still responsible for a full year of taxes, as Personal Property taxes are not pro-ratable.

We encourage complete and timely reporting and are available to assist taxpayers who have questions regarding the proper reporting for personal property.

2021 Revaluation is Underway!

UPDATE: Click Here to view a list of streets currently being inspected.

The Town of Killingworth has hired eQuality Valuation Services, L.L.C. of Waterbury Connecticut to assist the Assessor in conducting the October 1, 2021 revaluation of all Real Estate in Killingworth, as mandated by state law.

Under the Assessor's supervision, eQuality will collect and analyze information about all properties. An important part of the valuation process involves measuring the outside and listing interior features of each structure by a representative of eQuality. During the COVID-19 pandemic, the data collector will perform an exterior inspection only, which will involve the measurement and exterior review of all structures; the collector will also take a photo of the front of each building. At this time, there will be no interior inspections. If you are not home, we will leave a door hanger to let you know that we were there.

Fieldwork will begin January 2021.

All representatives will carry photo identification and the original letter of introduction signed by the Assessor. Homeowners are encouraged to ask for identification from the data collector. Their vehicles are registered with the Killingworth Resident State Trooper's Office.
The eQuality employee assigned to conduct the majority of inspections in the Town of Killingworth is Peter Hyde. Please click here for more information.

Data collection will occur in sections, and all property owners will be notified ahead of time. We will mail you a notification postcard several days before collection begins in your specific neighborhood, so you will be aware that a representative will soon be visiting your property.

Cooperate. After verifying the collector's identification, kindly allow him to do his work, which should be limited to: walking the exterior perimeter of your home, measuring the exterior of any structures/outbuildings, and taking a photo of the front of each building.

Participate. In the next few months, we will mail you a property data questionnaire. Carefully review your information and return the form in the pre-paid envelope. Please note it is still necessary to return the form even if there are no changes. A true and complete description of your property will result in an accurate assessment. All our efforts are made to be fair and equitable. Understand that taxes are driven by municipal spending, not by your assessment. Stay involved and informed by attending the Town meetings that will set the mill rate, which will determine the taxes you must pay.

If you have questions or concerns, please call the Town Hall at (860) 663-1765x506. Office staff may be working remotely due to COVID-19, so it is important to leave a message.

Michael Bekech and Shauna Ham
Assessor and Assistant Assessor, Town of Killingworth
The Assessor’s primary objective is to make sure that the property tax burden is distributed fairly among Killingworth property owners. The office assesses all taxable property located within the town according to state law and under state oversight. The assessor is also responsible for reviewing and approving various forms of property tax relief and exemptions, such as senior tax relief and veterans’ exemptions.

The assessor produces the annual Grand List, a record of all taxable and tax-exempt property in Killingworth. Under state law, the Grand List must be submitted by the end of January for all property ownership on October 1 of the previous year.
Frequently Asked Questions
Q. What is an assessment?
A. An assessment is the value placed on property appearing in the Grand List—the list of all taxable and tax-exempt property in the town. To determine the tax liability for a particular property, the property assessment is multiplied by the town’s mill rate. In Connecticut, an assessment is equal to 70 percent of the fair market value as established by the municipal assessor. For motor vehicles and business personal property, this assessment is recalculated annually as of October 1st. Real estate assessments are established during the town-wide revaluations, which are performed on a schedule established by state law.

Q. What is the fair market value, and who determines it?
A. Fair market value is a legal term defined by the courts and state statute as the purchase price that a property would bring on the open market, given prudent, knowledgeable, and willing buyers and sellers. Fair market value is the standard by which the fairness of all assessments is judged.

Buyers and sellers determine the fair market value of real estate. The appraiser or assessor analyzes real estate transactions that occur within a community and determines the factors that led to the final sale prices. These analyses are then used to estimate the market values of all properties in a community. Some of the typical factors used by an appraiser in estimating market values include location, condition, age, size, and quality of improvements.

Q. What guidelines must the assessor follow?
A. The assessor follows:
  • Connecticut General Statutes (primary Title 12)
  • relevant case law (which assists in interpreting these statutes)
  • regulations and administrative pronouncements from the State of Connecticut Office of Policy & Management, Intergovernmental Policy Division.
Q. How is the tax rate established?
A. The tax rate, or mill rate, is set annually by the elected Board of Finance members once the town’s budget has been approved in Town Meeting and the Regional School District 17 budget has been approved in a referendum. In simplest terms, the mill rate is the town’s levy—the amount of money the town needs to generate through the property tax in order to provide town and school district services—divided by the taxable grand list. In recent years, the education budget has accounted for about 80 percent of all tax dollars.

Q. How can I determine if my assessment is fair?
A. To judge the fairness of your assessment, two questions should be asked. First, does the assessment represent 70 percent of the probable selling price as of the revaluation date of October 1, 2016.

Second, is my assessment similar to that of comparable properties in town as of October 1, 2016. The assessor's office maintains information that will help you answer these questions, including a list of properties that have sold in town and the assessments of all properties in town.
