Chapter 103. 3 Compliance Data Environment (CDE)
Section 1. CDE Application and Use
May 17, 2011
(1) This transmits new IRM 4.103.1, Compliance Data Environment (CDE), CDE Application and Use.
(1) Compliance Data Environment (CDE) is a new system that replaced the Midwest Automated Compliance System (MACS). It is a workload identification, planning, and delivery system that operates in a web-based environment, and it is used to filter, order, classify and deliver returns.
Director, Operations Support
Small Business/Self Employed Division
Compliance Data Environment (CDE) is a workload identification, planning, and delivery system that operates in a web-based environment. It is used to filter, order, classify and deliver returns.
CDE utilizes the Infrastructure Shared Services (ISS) and Modernization & Information Technology Services (MITS)-18 General Support System (GSS) infrastructure to provide secured web-enabled access to its users through the Employee User Portal (EUP). The system architecture for CDE includes the use of a Business Logic server and Database servers (MITS-30) that physically reside at an Enterprise Computing Center.
CDE is a secure, centralized database supplementing the current Planning and Special Programs (PSP) return ordering and classification process through the campus. CDE replaced the Midwest Automated Compliance System (MACS).
CDE automates the classification process and provides a single source for all information required for workload management. CDE provides the information required to classify a return including a three-year return facsimile, entity data, related tax returns, and related information from external sources. Updates are automatically sent to AIMS. This on-line system incorporates an Electronic Classification Checksheet (ECC).
Returns are identified and delivered in Discriminant Function (DIF) descending order.
Some of the benefits of CDE are:
Streamlines the audit workflow, supports workload identification and delivery for both DIF and strategic initiatives
Provides a 3 year return facsimile, entity information, preliminary T-Account and related returns
Obtains information from outside sources - Integrated Data Retrieval System (IDRS), Currency and Banking Retrieval System (CBRS), and Third Party Data
Allows for on-line classification and review of returns reducing travel for classification details
Provides "just-in-time" inventory delivery (returns can be delivered in days instead of months)
Provides for faster input of returns into the audit stream
Allows users to create a Workload Set or Strategy Set from a Filter Result Set
Allows a Campus User to create a TC424 Request File or Tickler File from a Filter Result Set
Provides a paperless process
Allows for printing of case files to designated network printers
Data is available for the most current year and prior three years.
The following return types are available:
The CDE database contains tax return data from the return posted to Master File using Transaction Code (TC) 150. Subsequent amendments, duplicates, claims, etc., are not included in the database.
Tax return data refers to those lines that are transcribed at the Campus during processing (located in the Returns Transaction File (RTF)), as well as certain information from the Master File such as Post of Duty (POD), date of birth, audit history, and DIF score.
The following roles are found in CDE:
Virtual Inventory Administrator
User Administrator (CDE staff only)
System Administrator (CDE staff only)
Information and duties for each role can be found in IRM 126.96.36.199, CDE Roles.
CDE can be used for the following:
Classification of Returns
Delivery of Returns
CDE Research Requests
CDE Extract Requests
Case building provides additional information related to a tax return. The following information is available to order in CDE:
CDE facsimile (The CDE facsimiles resemble original tax returns in a 1 year format or 3 year comparative format.)
Third Party Data
A profile is a summary of one or more significant filing characteristics of a population of returns. It is limited to the information contained in the CDE database.
CDE can profile actual return filings of areas and analyze the makeup of their populations. Understanding the characteristics of a filing population can improve the processes of allocating resources, developing outreach activities, and identifying filing trends.
National Users can profile on a multi-area or national level.
Some examples of profiling are:
Return Type Analysis by Post of Duty (POD). For example, a profile can identify the number of 1040, 1120, 1065, 1120S and 1041 returns filed by POD and Activity Code. A profile indicating a large increase in the number of 1120S filings could indicate a change from 1120 to 1120S returns and a need to reallocate resources to 1120S audits.
Market Segment Analysis. For example, knowing how many taxpayers fall within a particular market segment is useful in developing educational efforts structured toward that market segment.
Trend Analysis. For example, the number of returns with Schedule A’s, Earned Income Credit, Foreign Earned Income, businesses with losses, etc. can be identified through this type of population analysis.
CDE has the ability to identify returns containing specific issues. For example, all returns in a specific market segment with a net profit percentage of less than 5%.
CDE can statistically stratify a Filter Result Set as well as generate a random sample of returns for testing. The Filter Result Set can be used to create a Workload Set, a Strategy Set, or a TC424 Request File or Tickler File for campus use.
A Compliance Initiative Project (CIP) is required for all CDE identified projects. The exception is for returns identified only by the same elements as a DIF order (Activity Code, POD) and which are above the locally defined DIF cutoff score. See IRM 4.17Compliance Initiative Projects for CIP procedures and information.
CDE is used for the online classification of returns. It contains the current processing year and 3 prior years data. It allows for a 3-year comparison of the taxpayer's return information (if it is available and ordered for classification). The multi-year comparison gives the classifier a better financial overview of the taxpayer, improving the selection process.
Through the CDE system, returns are identified and classified for various programs including, but not limited to the following:
Return Preparer Program (RPP)
When classifying individual returns, CDE can be used to view the K-1's received by that individual and also the related business returns of the K-1 payer, if ordered for classification.
When classifying business returns, CDE can be used to view the K-1's issued by the business, and the related shareholders’ or partners’ (payee) returns, if ordered for classification.
CDE is used to deliver returns from the CDE Virtual Inventory. A user can:
Deliver an entire Workload Set.
Deliver Case Files by Criteria Search.
Deliver a single Case File.
Reprint a Delivery Set.
Reprint a Delivery Set 3210.
Filters allow CDE Filter Creators to run queries against tax returns (individuals, business or trust) in the CDE database, then further refine the results of the queries by eliminating tax returns from the results with additional queries. A Filter is a set of conditions against which all returns in the filing population are compared. CDE allows users to design Filters to identify groups of returns containing particular issues or characteristics. For example, Filtering may be used:
To identify returns with potential for specific issues.
To identify returns by a preparer for a RPP.
To identify returns for a CIP.
CDE has the following thresholds when Filtering:
Four Filters can be run concurrently. If 4 Filters are already in process, the 5th Filter will go into a queue until 1 of the 4 is finished.
The maximum number of returns identified by a Filter is 500,000.
The maximum time a Filter will run is 24 hours.
The following Filters can be created in CDE:
Execution Filter - An Execution Filter is used to query the CDE database, which contains the current processing year and prior three years Return Transaction File (RTF) data plus related Master File data. When the Filter is executed it creates a Filter Result Set with all tax returns that meet the criteria of the Execution Filter definition.
Test Filter - A Test Filter is an Execution Filter with the Filter Result Set being limited to the first 25 returns that meet the Filter criteria.
Taxpayer Identification Number (TIN) Upload - A TIN Upload Filter is used to identify a set of tax returns by uploading a TIN List. A Filter Result Set is created by matching the TIN List against the tax returns in the CDE database. Instructions discussing the required TIN List format can be found in the CDE website "Job Aids" folder at http://mysbse.web.irs.gov/exam/tip/cde/jobaids/default.aspx.
Elimination Filter - An Elimination Filter is applied to a Filter Result Set (Execution Filter or TIN Upload) to remove specified returns from the Filter Result Set. More than one Elimination Filter can be applied to a Filter Result Set. Elimination Filters can be saved and reused and also be applied to other Filter Result Sets.
A Filter Result Set can then be used to create a:
Filter Summary Report - See IRM 188.8.131.52.5Filter Summary Report.
Filter Stratification Report - See IRM 184.108.40.206.6Filter Stratification Report.
Filter Sample Utility Report - See IRM 220.127.116.11.7Filter Sample Utility Report.
After the Filter results and reports have been analyzed, the User can create a Workload Set or Strategy Set from the Filter Result Set. Campus Users can also create a TC424 Request File or Tickler File.
Filter Results Sets are maintained on the system for two weeks and are automatically deleted if not accessed within this time. If the Filter Result Set is deleted, the Filter can be re-executed to create a new Filter Result Set.
There are two different files created specifically for Campus Filter Creators:
TC424 Request File
Campus Filter Creators can create a TC424 Request File for tax returns identified in a Filter Result Set or sampled Filter Result Set.
TC 424 Requests can not be created from a Test Execution Filter Result Set.
TC 424 Requests can not be created for business or trust Filter Result Sets.
The TC424 Request file is used by the Campus to further analyze the Filter Result Set data. CDE creates the file and transfers it to another Campus system for processing.
The following information is required when inputting a TC424 Request File:
Employee group code
Charge-out/label indicator (0 = Original return, charge-out label, 1 = Charge out and label only, 3 = No return, charge-out label)
Push code indicator
The following information is provided by CDE for each tax return in the Filter Result Set when CDE creates a TC424 Request File:
TIN type (0 = valid Social Security Number (SSN), 1 = invalid SSN)
Business Operating Division (BOD) code
Campus Filter Creators can create a Tickler File for tax returns identified in an Execution Filter Result Set.
Tickler Files can not be created by a Test Execution Filter Result Set.
Tickler Files can not be created for business or trust Filter Result Sets.
The Tickler File is used to further filter the returns through a process performed outside of CDE. CDE creates the file and transfers the file to another system from which the user can securely access it for processing.
The following information for each tax return in the Filter Result Set is provided when CDE creates a Tickler File:
Primary Social Security Number (PSSN) (9 digit primary TIN)
PSSN type (0 = valid SSN, 1 = invalid SSN)
Secondary Social Security Number (SSSN) (9 digit secondary TIN)
SSSN type (0 = valid SSN, 1 = invalid SSN)
Document Locator Number (DLN)
Preparer Employer Identification Number (EIN)
Preparer Tax Identification Number (PTIN)
PTIN - Indicator (PTIN - IND)
Electronic filing indicator (ELF- IND)
Total Positive Income (TPI)
Adjusted Gross Income (AGI)
Total deductions - Schedule A
Child Tax Credit
Additional Child Tax Credit
State Income/Sales Tax
State Income/Sales Tax Indicator
Other Income/Sales Tax Indicator
Other Income - Form 1040
Lifetime Learning Credit
Hope Learning Credit
When creating an Execution Filter, include "Common Favorite Fields" and only a few other lines of criteria to make the Filter process faster. Then create and apply an Elimination Filter to remove returns and further refine the Filter Result Set.
"Common Favorite Fields" are frequently used indexed fields that allow CDE to process Filters faster.
Each field in a Filter definition must be identified by the exact name used in the CDE data dictionary. Fields are classified as individual, business or trust in the Filter definition (e.g. the field AGI is only used in an individual Filter definition). To find the name for a field:
Click the "Find Criteria Field" icon to access a look up window containing form, fields and field definitions or
Start typing the field name and a list of options appears in a drop down list.
Use the following operators when creating Execution Filters and Elimination Filters:
= (equal to)
< (greater than)
> (less than)
<= (greater than or equal to)
>= (less than or equal to)
>< (not equal to)
The following values are used when creating Execution and Elimination Filters:
Numeric fields - e.g. AGI or number of dependents
Code fields - e.g. Activity Codes and North American Industry Classification System (NAICS) codes
Date fields (MM/DD/YYYY) - e.g. 06/04/2009
Cycle fields (YYYYWW) - e.g. 200949 for the 49th week of 2009
Tax periods (YYYYMM) - e.g. 200912 for December 2009
Year (YYYY) - e.g. 2009
Each line of an Execution Filter or Elimination Filter is connected to the next line with either an AND or an OR operator. If AND is used, a return must meet both criteria to be selected. If OR is used, a return must meet one of the criteria to be selected. When using AND and OR statements within a Filter, it is imperative that parenthesis be used to group each of those statements to ensure proper order. It is also recommended that the AND statements be entered at the top of the Filter and the OR statements at the bottom. The last line of the Filter is followed by an EXIT operator.
A "CDE Filtering Best Practices" document, which contains additional Filtering tips and Filter examples can be found in the CDE website "Job Aids" folder at http://mysbse.web.irs.gov/exam/tip/cde/jobaids/default.aspx.
A CDE Research Request is required for all Filtering requests.
See IRM 18.104.22.168, CDE Research Request Overview.
Access to CDE is a two step process:
Request access through the EUP
Then submit an Online 5081 for the requested user role(s).
See IRM 22.214.171.124, Access to CDE.
