Westport’s October 2025 revaluation raised residential values about 60 percent on average and set the assessments that will drive tax bills until the next revaluation, scheduled under state law for 2030. If you think your assessment is wrong, or you qualify for relief, here is how the process works.
The Board of Assessment Appeals
Connecticut assessments are 70 percent of the fair market value the town assigned as of the revaluation date. If you believe the town’s value is too high, you can appeal to the Board of Assessment Appeals. For the 2025 grand list, the filing deadline was Feb. 20, 2026. Connecticut sets that Feb. 20 deadline each year for appeals of the most recent grand list. An owner who disagrees with the board’s decision can take the case to Superior Court.
The strongest appeals rest on evidence, typically recent sales of comparable houses, an independent appraisal, or factual errors in the town’s record such as wrong square footage, bedroom counts or lot size. Check the town’s property record card for your house first. Errors there are the easiest thing to fix.
Relief for older and disabled owners
Westport runs a tax relief program for owners who are 65 or older or totally disabled, have owned and lived in the house for at least a year, and meet income limits. Applications are taken in person at the Assessor’s office from Feb. 1 to May 15.
The state’s Circuit Breaker program offers credits of up to $1,250 for married couples and $1,000 for single filers, with applications in the same Feb. 1 to May 15 window, according to the state Office of Policy and Management. Confirm the current income limits with the Assessor before applying.
For buyers
A buyer inherits the seller’s assessment. It does not change because the house sold, so a house bought well above its revaluation figure carries a bill based on the lower number until the next revaluation, and a house bought below it carries the higher one. Before you bid, look up the assessment, multiply by 13.2 and divide by 1,000. That is the bill. Our revaluation story explains why the typical bill rose this year even though the rate fell, and our ownership cost guide covers the installments.
