Following recent enquiries from FIs, we have obtained permission from the OECD to distribute the CRS schema XSD files via the Igor Forum, as these are not yet available from the OECD directly.
You can download the files packaged in the following ZIP file:
The structure of CRS XML is virtually the same as FATCA XML, and the Igor implementation of CRS is analogous to the implementation of FATCA in all relevant respects, so the transition from FATCA to CRS XML should be straightforward.
The CRS XSD files should be used in conjunction with OECD’s CRS user guide, which is annex 3 of the OECD Standard for Automatic Exchange of Financial Information in Tax Matters, and the Igor Schema Guide also applies equally for CRS as it does for FATCA.
