Assumed Business Name

Persons (sole proprietors) or General Partnerships conducting business in Indiana in a name other than the real name of the individual or general partnership [DBA] shall record an Assumed Business Name Certificate with the County Recorder (IC 23-0.5-3-4).
The Certificate of Assumed Business Name (State Form 30353 on the in.gov website) is generally required by most banks and lenders. It may be beneficial to have your financial institution review the form prior to recording the document. The cost to record this form is $25 via cash or check. 
Questions regarding business licenses and taxes should be directed to the Indiana Secretary of State website.
