Best Connecticut Property Tax Appeal Services in 2026 (Compared)
Last updated: June 26, 2026
Connecticut property tax appeals are filed with the local Board of Assessment Appeals (BAA). Connecticut is a town-based property tax state, meaning appeals go to the board of your municipality rather than a county office. The appeal period is typically February 1 through February 20 for most Connecticut municipalities. Connecticut has some of the highest property tax burdens in New England, particularly in Fairfield County (which includes Greenwich, Stamford, and Westport). On a $600,000 home at a 1.8% effective rate, a 10% reduction saves $1,080 per year.
