Sole Proprietorship or General Partnership ID Number


Sole proprietorships or general partnerships require no legal document filings or other formalities except compliance with State and local licensing and taxation requirements.   One of these requirements is registering your business with our Department so that your business personal property can be properly assessed, and the business can obtain a State or local license (if required).  Please review our Business Personal Property Brochure for additional information.  To obtain the Application for Unincorporated ID Number, please click here.

Most businesses will also need to register with the Comptroller of the Treasury's Central Registration Unit. Their website is wwww.marylandtaxes.com.
