The Internal Revenue Service, charged with implementing the biggest change in tax laws in 20 years due to Obamacare, has created eight offices and special "teams" to handle the chore, way more than initially revealed.

Besides the top office headed by the woman in the middle of the IRS-Tea Party scandal, there are seven others and a special enforcement team that make up an organization chart that mirrors the organization of the IRS itself, according to a Treasury Inspector General's report.

The June report focused on concerns that the IRS, which is filling the Obamacare offices with 2,137 agents and officials to make sure citizens and companies comply with the new health law or pay a fine, isn't clear on its new role and how many new workers it will actually need. For example, the IRS will be in charge of analyzing hospital "community benefit activities," which it has never done before.

But in that report was the organizational chart revealing the series of Obamacare offices. They are led by a steering committee that coordinates Obamacare implementation across the IRS. It is led by the agency's deputy commissioner for services and enforcement, the office linked to the IRS scandal. Ousted acting IRS Commissioner Steven T. Miller recently had that job.

Other branches include three program management offices, four services and enforcement offices, and services and enforcement exchange working teams.

From the IG report:

Appropriate Plans Have Been Developed to Implement Most Tax-Related Provisions of the Affordable Care Act.

To begin the major task of implementing the tax-related provisions of the ACA, the IRS created the following Executive Steering Committees, Offices, and Teams.

-- The ACA Executive Steering Committee (ESC) is responsible for overall program coordination and implementation of the ACA across the IRS. This committee is co-chaired by the Deputy Commissioner for Services and Enforcement and the Deputy Commissioner for Operations Support. It also includes the IRS Chief of Staff and other IRS executives, including the business operating division commissioners, et al.

-- Three program management offices (PMO): 1) Services and Enforcement; 2) Modernization and Information Technology Services (MITS);5 and 3) Health Care Council. These PMOs are accountable to the ESC for ACA implementation and work with the IRS business operating divisions to ensure efforts are successfully coordinated.

-- Four functional ESCs, each led by an executive chair, have responsibility for specific provisions in the ACA that directly affect the four business operating divisions (Wage and Investment, Small Business/Self-Employed, Large Business and International, and Tax Exempt/Government Entities).

-- The Services and Enforcement Exchange Working Teams are responsible for planning the implementation of the exchange provisions scheduled for 2014.
