Normally a change in name of a nonprofit corporation requires an amendment to the Articles or Certificate of Incorporation filed with the state. There is usually a modest filing fee involved. 

 

You will also have to notify the IRS when the change has been effected. A name change alone will not affect your tax-exempt status and will cause the IRS to associate your existing Tax ID number with your organization under its new name. You will also need to notify state taxing authorities and any state with which you are registered to solicit charitable contributions. There is normally no charge for these notifications.
