Your New Property Assessment Arrives in November — Here's What to Know

Brookfield is in the final stretch of its town-wide property revaluation, the reassessment of every taxable property in town that sets the values behind next year's tax bills. According to the town's revaluation page, notices showing each property's new assessment — alongside its prior assessed value — will be mailed in November 2026.

A revaluation does not set your tax bill by itself. It resets the assessed value of your property, which under Connecticut law represents 70 percent of its fair market value. Your actual tax bill still depends on the town's budget and the mill rate the town sets. A higher assessment does not automatically mean a proportionally higher bill, and a lower one does not guarantee a lower bill — what matters is how your property's value moved relative to the town as a whole.

If the number in your notice looks wrong, the town's process gives you a step before anything becomes final. The revaluation page says property owners will have a chance to meet with a member of the revaluation firm's staff to talk through their property's data and valuation. That informal meeting is the moment to raise factual errors — a wrong square footage, a finished basement that does not exist, a comparable sale that does not fit — because corrections made there are far easier than a formal appeal later.

For owners who still disagree after the informal step, Connecticut law provides a formal appeal to the Board of Assessment Appeals, with applications due by February 20, 2027. That deadline is set by statute and cannot be extended, so it is worth marking now even though the notices have not arrived yet.

A few practical steps for November: when the notice arrives, compare the new assessment with the prior one shown on the same notice, check the property details behind it for errors, and keep the notice somewhere you can find it in January, when formal appeal applications become available. The town's revaluation page carries the background on each phase of the process, from data collection through field review, for anyone who wants the full picture.

Brookfield is one of more than 30 Connecticut towns conducting a revaluation for the October 1, 2026 grand list, a cycle the state staggers so towns revalue every five years. Once set, a property's value generally holds for the full five-year cycle unless it is appealed, improved, or expanded.
