Reports, as specified below, are required from all U.S. persons coming within the reporting requirements, whether or not they are contacted by BEA. In addition, any person BEA contacts by sending them report forms must respond in writing. The response must be made by the due date of the report, either by filing the properly completed report form or by certifying in writing on the form that the person has no international services transactions within the purview of the Act or the regulations contained herein. The latter requirement is necessary to ensure compliance with reporting requirements and efficient administration of the Act.
