Systems

7.22.1.2 (02-04-2026) Systems Letter Information Network User-fee System (LINUS) is the user fee system for EO Determinations. Campus Support inputs the initial data to control the user fee for all paper determination letter applications. The information automatically transmits to the Modified EO-EP Determination System (MEDS). See IRM 3.45.1, Processing Employee Plan and Exempt Organization Determination Applications and User Fees. Pay.gov transmits user fee information from Forms 1023-EZ, 1023, 1024, and 1024-A to LINUS. The EP/EO Determinations Processing Adjustments Unit inputs data in LINUS for dishonored checks and refunds. See IRM 7.21.2, Processing User Fees. MEDS is the web-based information system for electronic case and inventory management that EO Determinations uses to process determination letter requests. See IRM 7.22.4, Modified EO-EP Determination System (MEDS) User Manual, for detailed MEDS system information. Employee Plans/Exempt Organizations Determination System (EDS) is EO's determination system of record. See IRM 7.22.8, EP/EO Determination System (EDS) User Manual, for detailed EDS system information. Employee Plans/Exempt Organizations Applications Control System (EACS) links EDS and the EO Business Master File (Master File). See IRM 7.21.8, EDS Unpostables, for information on data transfer from EDS to EACS. A case opening establishes a new entity on Master File (Transaction Code 000) or updates the existing entity (Transaction Code 016) if the applicant's EIN is included on the National Account Profile. EO can also execute name changes (Transaction Code 013) and/or address changes (Transaction Code 014) for existing entities. A case closing transmits information from EDS to Master File for cases closed with closing code 01, 02, 06, 09, or 11. Business Objects (BOBJ) is the management information system EO uses to gather, access, analyze, share, and correlate data from EDS and MEDS. Integrated Data Retrieval System (IDRS) is the system EO uses to access Master File for research and to update or correct unrestricted fields on Master File, when necessary. Enterprise Case Management (ECM) is the electronic system used by the Correspondence Unit to process and respond to correspondence received from taxpayers relating to their tax exempt status.
