In 1998 Congress enacted the IRS Restructuring and Reform Act prompting a comprehensive reorganization and modernization of the IRS. The IRS reorganized itself to closely resemble the private sector model of organizing around customers with similar needs.

The IRS is divided into three commissioner-level organizations to support its structure and ensure accountability:
