Windham County property tax appeals
The 2026 deadline was Friday, February 20 and has passed. The next window opens in 2027.
Reassessment schedules vary by locality in Connecticut. Your notice, when one arrives, states your deadline.
Appeals go to Your town or city Board of Assessment Appeals.
Connecticut towns and cities assess, not counties, and they assess at 70 percent of market value. Compare your assessment to 70 percent of what your home would sell for, and file with your local Board of Assessment Appeals on or before February 20.
- Your assessment is more than 70 percent of what your home would actually sell for.
- The record has an error in your home's size, condition, or features.
- Your town just revalued and your number jumped more than the market did.
- Your assessment already works out to about 70 percent of market value. That is the intended level, not an error.
- You are unhappy with the mill rate. The board reviews your assessment, not the tax rate your town sets.
Read the full explanation
In Connecticut your town or city assesses your home, not the county, and your appeal goes to your local Board of Assessment Appeals. Connecticut does not tax the full value of your home: it assesses at 70 percent of what the property is actually worth, so the number on your notice should be about seven tenths of what your home would sell for. That is the comparison that matters, and it is the one most people get wrong. You file a written appeal on or before February 20, and towns revalue on a five year cycle, so a revaluation year is the natural time to check. An appeal makes sense when your assessment works out to more than 70 percent of what your home would sell for, or when the record has an error. It will not help when your assessment already lines up with the market and you simply disagree with the mill rate. This is general information, not tax advice.
