Tax Assessor

In Trumbull, as required by Connecticut law, assessments are done based on 70% of the fair market value of all real estate, motor vehicles and business personal property.

Motor vehicle values are annually determined through the use of the NADA Guide and business personal property is valued through the use of annual declarations verified by independent audit.

The Office is open regular business hours Monday – Friday from 9am to 5pm. We are closed for legal holidays.
