DBA, short for "doing business as," refers to a name that you use for business that's different than your actual name. In Minnesota, your DBA is called an assumed name. You must register your DBA unless your business name is both your first and last name. For example, if your name is Abby Mimms, you wouldn't have to register "Abby Mimms Grocery," but if you wanted to use just "Mimms Grocery," you have to register. You must renew your DBA annually in Minnesota.

Publish your new assumed name in a legal newspaper in the county in which you will do business for two consecutive issues.
