For CRS, entities can either upload an XML file that complies with the OECD CRS schema, or they can use the Manual Entry filings to input their data into web forms, which will then be converted to the correct XML format prior to transmission to Partner Jurisdictions.
For CbC (once reporting functionality is available), the only option for reporting entities will be to upload an XML file that complies with the OECD CbC schema. There will not be a Manual Entry option for CbC, and other file formats (e.g. Excel) will not be accepted.
