Yes, it is possible to change the structure of an LLC after formation. Depending on the state in which the LLC was formed, this can be done through filing a certificate of amendment with the appropriate state agency or by updating the Operating Agreement that governs how the LLC operates. In some states, changing certain elements of an LLC’s structure may also require approval from all members. It is important to note that changes made to an LLC’s structure may have tax implications and should be discussed with a qualified accountant before proceeding.
