 1. Introduction 

 1.1. Purpose of This Document 

 The purpose of this document is to provide a general description of the FATCA Notification Schema V2.5 that 
 will be the basis for all electronic notifications from the Internal Revenue Service (IRS) to FATCA filers – 
 Foreign Financial Institutions (FFIs), direct reporting non-financial foreign entities (direct reporting NFFEs), 
 sponsoring entities, trustees of trustee-documented trusts, non-GIIN filers1, and Host Country Tax Authorities 
 (HCTAs) -- using the International Data Exchange Service (IDES). Throughout this user guide, the term “FFI” 
 is used to refer to FFIs, sponsoring entities, trustees of trustee-documented trusts, and non-GIIN filers. FATCA 
 XML files based on the FATCA Notification Schema V2.5 will only be generated by the IRS; FFIs, direct 
 reporting NFFEs, and HCTAs can use this guide to interpret notifications received from the IRS, and to 
 program their systems to receive and manage these files. [Note: HCTAs receiving reciprocal data from the IRS 
 are free to use the FATCA Notification Schema to format their notifications. However, this guide only 
 addresses the use of the notification schema from the IRS’s perspective.] 

 1.2. FATCA Notification Overview 

 A FATCA Notification is a message from the IRS to a sender of a FATCA Report file concerning the outcome 
 of processing the file as received by the IRS. A FATCA Notification is contained in a “transmission” file archive 
 through IDES to an international partner, either an FFI, direct reporting NFFE, or HCTA, in response to the 
 transmission and processing of a FATCA Report from that partner. 
 Transmissions containing notifications are prepared using the same process and components used to prepare 
 the FATCA Report transmission. When the IRS sends a notification, IDES will send an email to the FFI, direct 
 reporting NFFE, or HCTA that a file is ready for download. The email correspondence will reference the 
 “TransmissionID” of the original transmission from the FFI, direct reporting NFFE, or HCTA and the recipient 
 must access IDES to download the notification package. The FATCA IDES User Guide, Publication 5190, 
 provides detailed instructions on how to download notifications. 
 There are two types of notifications that the IRS will send in response to FATCA Report transmissions: 
   •  File Error Notification – If there is an error encountered in attempting to access file contents, the 
      notification email provides a summary of the transmission, the error code, and the instructions to correct 
      the error and resubmit the file. 
   •  Valid File Notification – This notification confirms that your file was received and processed successfully 
      and will document any record-level errors identified within the file. 
 
 File-level error conditions prevent the IRS from accessing and prpocessing the XML data within the FATCA 
 Report submission, and will trigger FATCA File Error Notifications. File level errors include the following: 
   •  Failed download, due to a file transfer interruption or other fault condition preventing file access on 
      IDES; 
   •  Decryption failure involving the encrypted payload file; 
   •  Decryption failure involving the sender’s encrypted AES key; 
   •  Failed decompression of decrypted payload files; 
   •  Invalid digital signature; 
   •  Invalid sender digital certificate; 
   •  Detection of one or more virus or non-virus security threats at any stage of processing of received 
 
 1 A non-GIIN filer is an entity that is required to file Form 8966 but is not required to get a GIIN. A non-GIIN filer, 
 such as a withholding agent, territory financial institution, third party preparer, or commercial software vendor, 
 will be issued a FATCA Identification Number (FIN) to enroll in IDES and submit FATCA reports. 

                                                                                                                  2

      transmission from IDES in which a file’s state is changed (initial download, unzipping the transmission 
      archive, decryption of AES key and payload files, payload decompression); 
 •  Detection of restricted characters or character combinations 
      (https://www.irs.gov/businesses/corporations/fatca-xml-schema-best-practices-for-form-8966) ; 
 •  FATCA Report payload file that cannot be validated against the FATCA XML Schema; 
 •  MessageRefId value consisting solely of one or more blank characters; 
 •  DocRefId value consisting solely of one or more blank characters; 
 •  Duplicate MessageRefId value (MessageRefId value received on a prior valid file). 
 
 Error Notifications will provide the FATCA Filer a 3-character code for the type of error; pre-defined text 
 describing the error, recovery actions, and due dates; and a hyperlink the sender can use to find additional 
 information and resources to resolve the error. 
 A Valid File Notification informs the filer of the following: 
 •  The specified FATCA Report file has been received; 
 •  No file errors were found; 
 •  Individual account, pooled, and nil reports contained with the specified file have been processed; 
 •  The number of total account, pooled, and nil reports received, and the number of FFIs including reports 
      (as Reporting FIs) in the file; 
 •  Error codes and descriptions of record-level errors detected in the file, including data elements and error 
      descriptions for field-level errors. 
 
 Additional information around interpretation of FATCA notification contents can be found on the FATCA Report 
 Notifications website at http://www.irs.gov/Businesses/Corporations/IRS-FATCA-Report-Notifications. 

 1.3. Notification Schema Files Covered in this Document 

 The FATCA Error and Valid File Notification types each have their own schema structure and data elements, 
 which are described in this guide. All schema files used for FATCA data exchange are available at 
 http://www.irs.gov/Businesses/Corporations/FATCA-XML-Schemas-and-Business-Rules-for-Form-8966. 
 The FATCA Notification Schema consists of three schema (.xsd) files: 
 •  BASE-FATCA-NOTIFICATION-2.5 – Base schema for common data elements and data types related to 
      FATCA notifications. Referenced by all main notifications schemas. 
 •  FATCA-FILE-ERROR-NOTIFICATION-2.5 (3 KB) – Main schema describing file level error notifications. 
 •  FATCA -VALID-FILE-NOTIFICATION-2.5 (8 KB) – Main schema for the valid file notifications. 
 
 The structure and data elements for FATCA Filer Error and Valid File Notification schemas are discussed in 
 this document. 

                                                                                                              3

 1.4.  Schema Element Descriptions 

 Each schema element is presented in terms of the characteristics in Table 1 below. 
                                    Table 1: Element Description 
 
       Characteristic                                   Description 
       Element                     The name of the schema element. Elements not described in 
                                    the guide are not supported. 
       Size                        The minimum and/or maximum size in characters of the 
                                    element value. 
       Cardinality                 The number of times an element occurs in an XML file. 
                                   If cardinality is not defined, then one and only one instance 
                                    should be included (minOccurs=1 and maxOccurs=1). 
                                   Where a data element is not used, then the associated 
                                    attribute(s) are not used. 
       Data type                   The data type for a data element value, such as numeric, string, 
                                    Boolean, date, time, etc. 
                                   XML supports custom data types and inheritance. 
       Requirement                 The requirement field for each data element and its attribute 
                                    indicates whether the element must be included in the XML 
                                    document. 
                                    Required: The data element is required for schema 
                                    validation and must be included in the Notification. 
                                    Optional: The data element is not always needed in the 
                                    Notification. Refer to the user guide to determine when it 
                                    should be included. 

       Description                 This contains the business definition for the element. 
 
 1.5.  How to Use this Guide 

 The notification schema files define how valid FATCA Notification XML files will be structured. This guide 
 contains additional information on how the IRS will use the notification schema to generate FATCA 
 notifications. This guide explains how the IRS will augment valid XML notification files to convey error and 
 valid file processing outcomes. 
 Each data element described in the FATCA XML Schema supports metadata, notifications and the FATCA 
 Report (Form 8966). The schema definition files provide the framework for discussion of data elements 
 presented within the guide. The FATCA XML schema definition files or .xsd files may be downloaded from the 
 IDES site on IRS.gov. 
 The diagrams included in this document illustrate the message structure and hierarchy relationship of 
 notification schema elements. These diagrams were developed using XMLSpy®, but the schema and sample 
 files can be viewed with other XML tools, such as XML Notepad. The table in Figure 1 describes the XMLSpy® 
 legend to interpret the diagrams in the text. If you are using a different XML tool, the icons and images may 
 vary. 
 Other organizations, such as HCTAs, receiving data from the IRS through IDES using the FATCA XML 
 Schema are free to use the FATCA Notification Schema to format their notifications to the IRS. However, the 
 perspective within this guide is restricted to IRS usage of this notification schema when responding to FATCA 
 XML files received through IDES. 

                                                                                                               4

                                  Box with full-line is a required report element. 
                   
                                  Box with dotted line is an optional report element. 
                    
                                  The child elements must appear in the sequence mentioned. 
                 
                                  Only one of the possible child elements may be present. 
                  
 Element descriptions are annotated with graphics generated using XML Spy ® which is provided by Altova 
 (www.altova.com). A tutorial for XMLSpy can be found here. 

 1.6. Restrictions on Text in FATCA String Characters 

 The UTF-8 encoding standard must be used in all FATCA XML reports. In addition, there are important 
 restrictions on the use of certain characters and character combinations in FATCA Report files to which filers 
 should adhere to in order to avoid a File-Level Error. 

 1.7. Compatibility with FATCA Notification Schema V2.2 

 The changes from FATCA Notification Schema V2.2 to 2.5 include: 
  •  New enumeration code "NIL_REPORT" for FATCAReportTypeCdType; 
  •  New enumeration codes (8013-8018) for nil report record level errors in RecordLevelErrorCdType; and 
  •  Updated enumerations in ISO3166Alpha2CountryCodeType according to CountryCode_Type in 
      isofatcatypes_v1.1.xsd in FATCA XML 2.0. 
 In addition, the “version” attribute on the “FATCAFileErrorNotification” schema element is now set to “2.5”.

 2. FATCAFileErrorNotification 

 This section discusses the data elements of FATCA-FILE-ERROR-NOTIFICATION-2.5.xsd schema file, which 
 will be used to transmit error notifications when the conditions outlined in Section 1.2 above are detected by 
 the IRS on FATCA Report files received through IDES. The structure of a FATCA error notification is shown in 
 Figure 2 below. 
                 Figure 2: FATCAFileErrorNotification Type Layout 
 
 An example FATCA File Error Notification in XML format for the “NDC” (failed decryption) case is shown in 
 Appendix B. 

 “FATCAFileErrorNotification” Attribute: The “FATCAFileErrorNotification” element is currently the only 
 element in the FATCA-FILE-ERROR-NOTIFICATION-2.5.xsd schema with an attribute. The Attribute name 
 is “version”, the type is “string”, and the value is fixed at “2.5”. 

                                                                                                                6

 Many of the sub-elements of the FATCAValidFileNotification element have considerable overlap with their 
 counterparts in the FATCAFileErrorNotification element documented in Section 2. The following 
 FATCAValidFileNotification subsections will build out the differences with the FATCAFileErrorNotification 
 and make reference to the corresponding subsections of Section 2 where needed. 

 An example Valid File Notification in XML format for the “NVF” case is shown in Appendix C. 
 
 3.1. FATCANotificationHeaderGrp 

 The valid file schema “FATCANotificationHeaderGrp” data element is similar in purpose and structure to its 
 counterpart in the error notification schema. All seven sub-elements for the FATCANotificationHeaderGrp 
 are documented in Sections 2.1.1 through 2.1.7. The only difference with the sub-elements here versus the 
 discussion for the FATCAFileErrorNotification occurrences is that the “FATCANotificationCd” sub-element 
 takes on only one value “NVF” for valid file notifications: 

 The FATCANotificationHeaderGrp is depicted in Figure 7. 

                                                                                                           18

 Appendix A:     Glossary 
 
      Terms                                Description 
 Record          A record is a subset of a file that is specific to an account, pooled, or nil 
                 report. A single account report or pool report is equivalent to one paper 
                 Form 8966. A record may contain only one account report or pooled 
                 report. 
 Report          A group of records assembled into a single XML instance. A FATCA 
                 report may contain zero, one, or many records from one of more FATCA 
                 Filers. 
 File            Records sent to the receiving tax jurisdiction. A file may contain one 
                 FATCA report that may consist of zero, one, or many reports. 
 Transmission    A set or group of files moved through IDES. All transmissions will share a 
                 similar structure consisting of multiple files with specific purposes. These 
                 files will be zipped into an uncompressed archive using common tools 
                 available with common user operating systems (Windows, MacOS, and 
                 Linux/Unix). The specific files within the transmission archive structure 
                 and their filename conventions sent to IDES are described below: 
                 1.  Encrypted FATCA Report (from FFI/NFFE/HCTA) or Notification 
                         (from IRS): filename has the form [SenderGIIN]_Payload, where 
                         SenderGIIN is the IRS-issued GIIN of the sender in full GIIN 
                         format. 
                 2.  Encrypted AES Key: AES key used to encrypt payload in 
                         [SenderGIIN]_Payload: filename has the form 
                         [ReceiverGIIN]_Key, where ReceiverGIIN is the GIIN of the 
                         recipient whose public key was used to encrypt the HCTA key. 
                 3.  Sender Metadata: contains the unencrypted metadata used by 
                         IDES to identify the sender and route to the recipient; the filename 
                         has the form [SenderGIIN]_Metadata.xml, where SenderGIIN is 
                         the GIIN of the sender in full GIIN format. 

 Payload         The electronic files that are packaged / encrypted / compressed in the 
                 format required by IDES and are transmitted to the receiving party by 
                 IDES. 
 Sender Metadata Sender metadata is the information provided to identify the Sender and to 
                 ensure that the recipient can correctly process FATCA Reports or 
                 Notifications. 
 Notification    A Notification is a message sent from the United States Internal Revenue 
                 Service (IRS) to an FFI, direct reporting non-financial foreign entity 
                 (NFFE), or Host Country Tax Authority (HCTA) in response to the 
                 transmission of a FATCA Report from that partner. 

                                                                                               37
