The State Department of Assessments and Taxation (SDAT) values all homes in Maryland, not the county. SDAT runs one local assessment office in each of the 23 counties and in Baltimore City, each led by a Supervisor of Assessments. Your county or city sets the tax rate and sends the bill. Find your county for contact details, local tax figures and a step-by-step guide.
