Business Name Change

Business owners and other authorized individuals can submit a name change for their business. The specific action required may vary depending on the type of business. If the EIN was recently assigned and filing liability has yet to be determined, send Business Name Change requests to IRS-Stop 343G, Cincinnati, OH 45999.

In some situations a name change may require a new Employer Identification Number (EIN) or a final return. See Publication 1635, Understanding Your EIN, to make this determination.
