SECTION 12.1
THE INTERNAL REVENUE SERVICE
The tax laws of the United States are administered by the Internal Revenue Service (IRS).
In administering the tax law, the IRS has the responsibility for determining, assessing, and
collecting internal revenue taxes and enforcing other provisions of the tax law. The IRS is a
division of the Treasury Department.
The IRS organization currently consists of a national office in Washington, D.C., ten
service centers, and various oper ational offices throughout the USA. The national office
is the headquarters of the commissioner of internal revenue and various deputy and asso-
ciate commissioners. The commissioner of internal revenue is appointed by the president
of the United States with the advice and consent of the Senate. The responsibilities of the
commissioner are to establish policy, to supervise the activities of the organization, and to
act in an advisory capacity to the Treasury Department on legislative matters. In addition,
the commissioner is responsible for the collection of income tax, auditing of tax returns,
intelligence operations, and appellate procedures.
Service Centers
In addition to the various operational offices discu ssed below, the IRS currently maintains
ten service centers. At these service centers, the IRS computers process the information
from tax documents such as tax returns, payroll tax forms, Form 1099s, and withholding
forms. Service centers are located in the following cities:
Atlanta, GA Fresno, CA
Austin, TX Kansas City, MO
Andover, MA Memphis, TN
Holtsville, NY Ogden, UT
Cincinnati, OH Philadelphia, PA
The IRS also maintains a national computer center in Martinsburg, West Virginia,
where information from various service centers is matched with records from other service
centers. This cross-matching of records helps to assure that taxpayers report all their
income and do not file multiple refund claims.
The 1998 IRS Restructuring Act
1
The Service wa s completely reorganized under the 1998 IRS Restructuring Act (RRA 98)
which resulted in the new structure as shown in Figure 12. 1. During the years follow ing
RRA 98, the IRS was reorganized along functional lines, with district and regional offices
eliminated, and the entire operational structure significantly changed and decentralized.
Prior to RRA 98, the IRS organizational structure was primarily organized geographi-
cally with four regional offices headed by regio nal commissioners who were responsible
for collection of income taxes, audit of returns, intelligence operations, and appellate pro-
cedures. The regional commissioners also supervised the work of the district directors
within their regions. The IRS district offices were located in every major city in the United
States. Each office had a district director in charge of administering the func tions of the
office. District offices were the lowest level of the IRS and were responsible for the various
day-to-day operations such as providing information to taxpayers, auditing tax returns, and
collecting taxes.
