ACH Refund
US Customs and Border Protection (CBP) requires ACH enrollment to receive refunds resulting from corporate or individual overpayment of Customs duties, taxes, fees, and miscellaneous or invalid payments submitted to CBP, electronically through Automated Clearinghouse (ACH). After enrolling for ACH refunds, your refund will automatically be deposited directly into your bank account. ACH refunds replaces the process of depositing Treasury checks, as well as eliminating the delay and risk associated with fraud, undeliverable addresses, and lost mail when receiving Treasury checks through the mail.
Importers, brokers, filers, sureties, service providers, facility operators, foreign trade zone operators, and carriers are required to use their ACE Portal account to enroll in electronic refunds using the Federally assigned taxpayer identification number (TIN), Social Security number, or US Customs and Border Protection assigned number, and a U.S. bank account with U.S. bank routing number.
