Overview LLCs Incorporating Business Licenses DBA Filings

Get an Illinois DBA

If your business operates under an alternate name, it must register its "Doing Business As" (DBA) name with the appropriate state, county, city, or town government. For example, John Smith might register "Smith Plumbing" as a DBA. Likewise, "Helen's Bakery, Inc." might register the DBA, "Helen's Catering." Corporations and LLCs often file DBAs to market a separate product or service.

Some government offices refer to a DBA as a "trade name," "assumed name," or "fictitious name." In any case, a DBA name allows your business to operate under a name other than its legal name.

Get the Facts About Illinois DBAs:

  • Corporations and LLCs file DBAs with the Illinois Secretary of State.
  • Corporate and LLC DBA names expire on the first day of the anniversary of filing in the next year evenly divisible by 5.
