Scope of the Position:

The Commissioner of the Internal Revenue Service (IRS) oversees the collection of approximately $3.1 trillion in tax revenue for the United States federal government every year. As of FY 2014, that consisted of nearly 240 million tax returns. The Commissioner works to ensure a balance between the responsibilities of providing taxpayer services and tax code enforcement, and he or she determines the overall direction of the Agency. The position works to promote equity and integrity throughout the collection process and serves for a five-year term. The Commissioner may be reappointed following the end of a term. 

Illustrative Management Challenges:

There are multiple management challenges that will warrant continued attention for the foreseeable future.

Alleged Political Bias in 501(c)4 Designation

There is continued effort from current Commissioner John Koskinen to address the ways in which the IRS has processed 501(c)4 applications.1 The Agency has been scrutinized by the U.S. House Oversight and Government Reform Committee for its alleged use of political bias toward various organizations applying for 501(c)4 designation. Conservative groups complained of delays, burdensome requests, and intimidation from interactions with the Internal Revenue Service during the application process for tax-exempt status.2 It should be noted that no formal ruling has been made regarding the alleged political bias of the IRS. However, this issue is still something that the future IRS Commissioner will likely have to address in the next administration. Remaining focused on carrying out the Agency's mission while implementing best management practices in the midst of such a political issue will undoubtedly pose a significant challenge for the future Commissioner.

Information Security

The Government Accountability Office has developed numerous reports over the years detailing the various informational control updates that would improve IRS systems.3 According to a 2016 report, the "IRS has not effectively implemented elements of its information security program," exposing the Agency to vulnerabilities. Without addressing unresolved and newly identified control deficiencies and updating policies, test and evaluation procedures, and remedial action procedures, the IRS's financial and taxpayer data will remain vulnerable to attack, use, or disclosure. In another report, GAO found that "weaknesses remained with identifying and authenticating users, authorizing users' level of rights and privileges, encrypting sensitive data, auditing and monitoring network activity, and physically securing its computing resources."4 The report indicates that until the IRS effectively implements adequate security practices, taxpayers will "continue to be exposed to unnecessary risk." These internal changes also seek to improve the Agency's security and customer service and streamline compliance programs.5
