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 the IRS address where you file your return. In some situations a name change may require a new Employer Identification Number (EIN) or a final return. See Publication 1635, Understanding Your EIN PDF, to make this determination.
