It is always important to carefully review your tax bill and/or notices of assessments, but even more so in the year in which your city or town conducts a revaluation.
Each assessment should be carefully reviewed, even if your assessment has not increased substantially, as an appeal immediately after a revaluation maximizes a property owner’s potential tax savings.
Connecticut law requires each municipality to conduct a general revaluation of the real estate within its borders at least once every five years. Given the passage of Connecticut Public Act 22-74, the State’s Revaluation Schedule has shifted slightly with the creation of five new Revaluation Zones which purportedly allows for the coordination of revaluation services and provides a mechanism to create efficiency and municipal cost savings. This new law does not change the fact municipalities must conduct revaluations in Connecticut every five years, however the result is that some municipal revaluations are a year shorter or longer to transition into the new schedule.
The purpose of a revaluation is for a municipality to determine the market value of real estate to be used to calculate property taxes. Once a property’s value is set in a general revaluation, it remains constant over the entire five-year cycle, absent appeal, demolition, improvements or expansion. Of course, the annual taxes usually increase, as a municipality’s mill rate increases incrementally from year to year.

Revaluation Schedule – 2025
If your municipality is conducting a general revaluation for the Oct. 1, 2025, Grand List, you will soon receive a notice of tax assessment change.
Once the notices are issued, there may be a chance to meet informally with the assessor to discuss the new assessment, which should represent 70 percent of the fair market value of your real estate. However, if a property owner wishes to challenge the assessment formally, a written appeal must be filed with the local Board of Assessment Appeals by the Feb. 20, 2026, statutory deadline.
It is in your best interests to be proactive in monitoring the revaluation process and your new assessment so all necessary steps to ensure the assessment is equitable.
