Office of the Assessor


It is the Assessor’s responsibility to establish fair and equitable values for all real-estate, taxable personal property, and taxable motor vehicles located within the city. The assessment year begins October 1st and continues to September 30th of each year. All assessment work must be completed for the finalization of the Grand List on January 31st.

Additional Information

2022 Revaluation update - Final assessment notices sent to property owners.

The City has completed its statutorily mandated property revaluation, and final assessment notices were mailed the first week of February 2023 and should be received by City property owners shortly thereafter.  

Property owners should not attempt to estimate their 2023-24 tax bill using the new assessment and current mill rate as they will over-estimate the taxes they owe.  The mill rate will be adjusted as part of the budget process beginning in March 2023. It is anticipated that the mill rate will be reduced as the Grand List increases.

All property assessments and record information is publicly available on the internet.  It can be accessed by following the “Housing & Property Information” link at the top of this page. 

Property owners who wish to contest their assessment must submit a written appeal to the Board of Assessment Appeals no later than 4:30 pm, Friday February 17, 2023.   The Board will schedule hearings to take place during the month of March.  Property owners, or their assigned representative, must appear before the Board, or a member of, to take an oath and provide testimony regarding the valuation of their property.

Appeal forms are available online or at the Assessor’s Office.

The revaluation project began in early 2022 and continued through this October.   Employees of MuniVal conducted field inspections of properties, and sent data verification letters to residential property owners, and verified sales data prior to determining the new assessments.

New market values were compiled for all 15,800 parcels in Middletown by considering sales that have taken place in the last two years. The new values reflect the estimated market value as of October 1, 2022. All property in Connecticut is assessed at 70% of value by statute.

The purpose of a revaluation is to establish the current market value of all property within the City as of the assessment date, thereby creating an equitable distribution of property taxes.  Not all properties have changed in value equally since the last revaluation in 2017. Some properties may have deteriorated, while others may have undergone renovations. Once the assessment value for a property has been determined it will remain in effect until the next revaluation in 2027 unless the property is physically altered.

Final assessment notices issued February 1st will also reflect any exemptions or use classifications for which the property owner has been approved. For greater clarity on potential exemptions, eligibility or the application process, residents should call the Assessor’s Office at 860-638-4930.
