Local Tax Registration
Local taxes in Maryland require no additional registration.  Local taxes are usually collected as part of the various State tax systems.  Questions about local property taxes collected by the State should be directed to the County Supervisor’s Office of the State Department of Assessments and Taxation for the county where the business is or will be located.
