DBAs for Sole Proprietors
Sole proprietors often file DBAs in order to do business under a name other than their personal names. For example, John Smith might register "Smith Plumbing" as a DBA.
If you operate your business under a name other than your personal name, you will need to register your DBA with the appropriate state, county, city, or town office.
The Company Corporation can help sole proprietors file DBAs with some state and local government offices.
