While the XML schema has been primarily designed to facilitate the exchanges of CRS information between taxadministrations, the XML schema can also be used for domestic reporting of CRS information by ReportingFinancial Institutions, to the extent permitted under domestic law of the relevant jurisdiction.

Part of the technical solution to support this common standard is a schema and related instructions. A schema is a data structure for holding and transmitting informationelectronically and in bulk. XML “extensiblemarkup language” is commonly used for this purpose. This User Guide explains the information required to be included in each CRS data element to be reported in theCRSXMLSchemav3.0. Italso contains guidance onhowto make correctionsofdata items within a file that canbe processed automatically. How the CRS User Guide links to the CRS Schema This User Guide is divided into logical sections based on the schema and provides information on specific dataelements and any attributes that describe that data element. The CRS Schema Information sections are: I.Message Header with the sender, recipient, messagetype,reportingperiodII.Controlling Person or Account Holder details if anindividualIII.Account Holder if anentityIV.CRS Body; Reporting FI and Reporting Group and Account details The numbers of the sections are reflected in the numbering of the diagrams in Appendix A. The CRSXMLSchema is designed to be used for the automatic exchangeoffinancial account informationbetween Competent Authorities(“CAs”).In addition, the CRS could also be used for domestic reporting byFinancial Institutions (“FIs”) to domestictaxauthorities under the CRS. Items relevant for domestic reporting onlyare shown in[brackets]. The CRS schema is re-using the FATCA schema and elements of STF, so there are some elements in the CRSschema that ar
