General¶
The Collection Due Process Tracking System (CDPTS) is a cross-functional inventory system to track CDP Inventory from time of receipt through resolution. It allows Compliance areas to research CDP cases utilizing an IDRS Command Code (CDPTR) or input and update CDP cases via the web based Intranet system.
A Collection Due Process Record is added to a module on IDRS when a Form 12153 or other adequate CDP request is determined to be valid.
CDP Cases may be researched using Command Code CDPTR(Definer T), which will display the most recent actions on active cases selected by primary TIN.
Using CDPTR Definer T¶
CDPTR Definer T is designed to be used by Customer Service Representatives speaking with Taxpayers about their COLLECTION DUE PROCESS requests. It provides them with a summary of the current status for the request(s) of the Primary Taxpayer.
CDPTR Definer T is activated by inputting the formatted TIN of the Primary Taxpayer. See Exhibit 2.4.57–1.
CDPTR with Definer T produces a formatted summary of the current status of the case. Included in the summary is the Tin, Filer-Code, Tax Period, Request Number, IRS Rcvd Date, Name Ctrl, MFT, Case Type, Location Code, Office Function, Secondary TIN and Reason Code in the information about the current stage of the case. See Exhibit 2.4.57–2.
