Chief Information Officer
-
The Partnership Control System (PCS) is used to create, monitor and update information related to Partnership and Investor examinations.
-
Purpose: This IRM provides instructions on how to use IDRS command code TSNOT.
-
Audience: Campus Revenue Agents (RAs), Tax Compliance Officers (TCOs), Tax Examiners (TEs) and Clerks working pass-through entities and/or their investors linked on the PCS.
-
Policy Owner: Chief Information Officer
-
Program Owner: Information Technology/Application Development
-
Primary Stakeholders: SB/SE, Large Business and Industry (LBI), and Appeals
-
Program Goals: PCS is a database used to create an electronic linkage between pass-through entities and their underlying partners. Linking in some instances is mandatory. Linkage allows for the proper control of statutes and ensures all relevant partners are processed.
-
PCS was created to monitor and control pass-through entity investors. Pass-through entities can have many partners and many levels of tiering. Tiering occurs when an investor in a pass-through entity is also a pass-through entity. This complexity can make it difficult to keep track of statutes and monitor all the investors.
-
PCS control is a policy that was established in response to the partnership provisions of the Tax Equity and Fiscal Responsibility Act (TEFRA) of 1982. It has been expanded to cover other pass-through entities that fall outside of TEFRA.
-
The Director, SB/SE, Headquarters, Examination Field and Campus Policy is responsible for:
-
Coordinating and Implementing PCS enhancements; and
-
Coordinating resolutions for PCS Systemic problems
-
-
The SB/SE Program Manager, Examination Field and Campus Policy, Campus Exam & Field Support is responsible for:
-
Ensuring that PCS procedural changes and computer program changes are implemented and coordinated with area office and campus examination personnel; and
-
Monitoring and evaluating area office and campus examination PCS quality control procedures
-
-
The campus PCS Coordinator is responsible for:
-
Identifying and resolving technical problems; and
-
Identifying and coordinating the resolution of PCS systemic problems
-
-
Program Reports: PCS generates a variety of reports used to monitor the inventory and related statutes. The data source for the reports is the Partnership Information Control File located in Martinsburg, WV.
-
Program Effectiveness: PCS is used to help identify the effectiveness of the Campus Pass-Through Function program. PCS shows the number of investors linked within a pass-through structure. Failing to link partner returns timely can result in barred statutes or the need to follow burdensome procedures such as manual assessments or untimely notice procedures.
-
IRS will implement access control measures that will provide protection from unauthorized alteration, loss, unavailability, or disclosure of information.
-
SACS controls all the IDRS user accesses and permissions.
-
