CDX Smart

File Country-by-Country reports with confidence

Tax authorities require that Country-by-Country data be converted into XML, based on local specifications. This may include message and document referencing for audit purposes, header messaging containing metadata relating to the reporting entity, data conversion into specific codes, and submission encryption. These complexities mean software is required.
