Carroll personal-property declarations are a March 1 assessor job

January 1 is the date that starts Carroll County personal-property tax paperwork, not the day the bill shows up. That March 1 deadline comes early. By March 1, people and businesses declare taxable personal property to the Assessor. The list can include motor vehicles, boats, trailers, livestock, farm machinery, and business furniture or equipment.

This is assessor work, not collector work. The Assessor values property, transfers real-estate ownership records, shares property information, issues certificates of non-assessment, and points residents to Carroll County GIS maps. The Collector-Treasurer comes later for bills, payments, and receipts. If you sold a truck, bought equipment, moved into the county, or need a non-assessment certificate, start with the Assessor.
