Our Other Divisions

The IRS depends on an extensive network of business units to keep our overall operation working. From the Chief Financial Officer organization to the Criminal Investigation unit, to Research, Analysis, and Statistics, to the Taxpayer Advocate Service, we provide services across the board that support both our internal and external operations. Each division employs a number of full- and part-time employees, and some employ seasonal and temporary workers, as well.

Learn about our top four divisions.

Our operational divisions include:

Agency-Wide Shared Services (AWSS)
AWSS provides a very broad array of complex administrative support services to every IRS employee. These comprehensive services include real estate, facilities management, occupational safety, records and files management, career learning centers, travel services, contracts and procurement, and the administration of Equal Employment Opportunity programs and processes.


Appeals
Independent by statute and staffed by highly trained professionals, our Appeals division provides alternative dispute resolution for any taxpayer contesting IRS compliance actions. Appeals represents the last opportunity for the IRS and a taxpayer to resolve disputes prior to litigation, and ensures that all taxpayers can receive an impartial review of their tax case. This impartial review is essential to the integrity of the American tax system.


Chief Counsel
As the principal legal advisor to the IRS Commissioner, the Chief Counsel is concerned with the interpretation, administration and enforcement of the Internal Revenue laws. This division provides legal guidance and interpretative advice to the IRS, the Treasury Department and to taxpayers. Separate Division Counsels report to the Chief Counsel and provide similar advice to each of the major IRS technical Divisions.


Chief Financial Officer (CFO)
The IRS Chief Financial Officer (CFO) organization is responsible for the custodial accounting of more than $2 trillion in taxpayer payments, and manages the IRS' $10 billion annual operating budget. The CFO also advises the IRS Commissioner and other top executives on issues dealing with financial management and systems, strategic planning, performance management, budget formulation, budget execution and internal controls.


Communications & Liaison (C&L)
C&L touches every aspect of the IRS mission through its information-sharing activities — from communicating internally with employees to communicating with taxpayers, Congress and state and local agencies. Thousands of media contacts and information requests are managed by this vital division, which also assists taxpayers in understanding and meeting their tax responsibilities.


Criminal Investigation (CI)
The American system of voluntary tax compliance relies heavily on self-assessments of what tax is owed. When individuals or corporations deliberately don't comply with the tax laws, Criminal Investigation — the investigative and law enforcement arm of the IRS — performs financial investigations and prepares potential criminal prosecutions in order to promote compliance and confidence in the fairness of the tax system.


Equal Employment Opportunity & Diversity (EEO&D)
EEO&D is located in IRS Headquarters, and reports directly to the IRS Commissioner. This division provides expert guidance and recommendations to senior management to help ensure that IRS employees support diversity goals and understand their EEO rights and responsibilities. It also provides guidance on applying civil rights laws with integrity and fairness to all.


Human Capital Office (HCO)
The HCO mission is to make the IRS an employer of choice and a leader in human capital planning and management. It develops strategies and tools for recruiting, hiring, developing and retaining a highly skilled and high-performing workforce. HCO also develops and implements technology-enabled systems to improve human capital planning and management, and to empower employees to achieve their potential.

Mission Assurance & Security Services (MA&SS)
The MA&SS division delivers an integrated approach to assist all IRS operating units in maintaining secure facilities, technology and data. It is organized into four core areas of work: Information Technology Security, Physical Security, Personnel Security and Emergency Management — providing critical protection to people and systems.


Modernization & Information Technology Services (MITS)
Our MITS division provides IT solutions that anticipate and meet current IRS-wide needs, while focusing on modernizing our systems. Responsible for strategic technology planning, data administration, technology standards, privacy assurance and telecommunications, MITS empowers employees with customer-centered products, services and support.


Office of Professional Responsibility (OPR)
IRS' Office of Professional Responsibility establishes, communicates and enforces Tax Practitioner standards of competence, integrity and conduct. These practitioners include attorneys, CPAs, enrolled agents and others who represent taxpayers before the IRS. They are unrestricted as to which taxpayers they may represent, what types of tax matters they may handle, and before which IRS offices they may practice.


Research, Analysis & Statistics (RAS)
This division provides a wide range of complex analytical research for both IRS and other federal agencies. Staffed by analysts, economists, statisticians and researchers, RAS includes offices devoted to Program Evaluation and Risk Analysis, Statistics of Income and the National Research Program aimed at reducing taxpayer burden through analyses of tax compliance data.


Taxpayer Advocate Service (TAS)
The Taxpayer Advocate Service (TAS) is an independent organization within the IRS, led by the National Taxpayer Advocate. The Taxpayer Advocate Service helps individual and business taxpayers resolve problems with the IRS by:

  • Ensuring that taxpayer problems not resolved through normal IRS channels are promptly and impartially handled
  • Assisting taxpayers who are facing hardships
  • Identifying issues that impact taxpayer rights, increase taxpayer burden, or create other problems for taxpayers, and then bringing these issues to the attention of IRS management
  • Recommending administrative and legislative changes through the National Taxpayer Advocate’s Annual Report to Congress

Each state, the District of Columbia, and Puerto Rico has at least one Local Taxpayer Advocate, who is independent of the local IRS office and reports directly to the National Taxpayer Advocate.
