Treasury opens tariff‑refund claims portal May 11 for $166B in refunds

Tariff refunds are finally moving from court theory to actual cash. But the key agency here is U.S. Customs and Border Protection, not Treasury. CBP opened the first phase of its electronic claims tool on April 20, 2026, and the first refunds are expected to start going out on or after May 11. The stakes are huge — roughly $166 billion in duties may need to be returned after the Supreme Court knocked out a set of Trump-era tariffs imposed under the International Emergency Economic Powers Act. (cbp.gov) ### What actually opened on April 20? CBP launched the first phase of a tool called CAPE inside the ACE Portal — basically the government’s trade filing system. This is the electronic path importers and customs brokers use to submit refund requests for IEEPA duties. The point is to move claims through one standardized channel instead of a patchwork of manual fixes. (cbp.gov) ### Why are refunds happening at all? Because the legal foundation for those tariffs broke. The duties at issue were imposed under IEEPA, an emergency-powers law. The Supreme Court ruled in February that the administration could not use that authority for these tariffs, which turned previously collected duties into money the government now has to unwind and return through the customs system. (cbsnews.com) ### So is May 11 the portal date? Not quite. That is the big correction to the headline. The portal itself did not wait until May 11. CBP said phase one of CAPE went live on April 20. May 11 is the earliest date for the first refund payments, and Reuters said CBP later estimated some electronic refunds could start as soon as May 12. In other words — portal first, money second. (cbp.gov) ### Who can actually get paid? The eligible party is generally the importer of record — or a broker acting through the proper account setup. CBP’s fact sheet says importers and brokers need an active ACE Portal account and separate bank information for refunds. That detail matters more than it sounds. If the refund banking setup is missing, CBP says the refund will not be processed. (cbp.gov) ### Why is this taking so much plumbing? Because customs refunds happen entry by entry, not with one giant “send money back” button. Importers need to identify which entries paid IEEPA duties, match those records, and submit valid declarations through the portal. Think of it less like a stimulus check and more like reconciling millions of line items in a tax au(cbp.gov)routing this through a normal Treasury consumer-payment page. (cbp.gov) ### How big is the queue? Very big. Public reporting has pegged the refundable pool at about $166 billion, with more than 330,000 importers potentially affected. Some reports also describe tens of millions of customs entries sitting behind the process. Even if the legal issue is settled, the operational backlog is still the real bottleneck. (cbsnews.co([cbp.gov)s now? Speed and clean filings. Companies that already have ACE access, refund banking instructions, and organized entry records should be in better shape. Everyone else may discover that “refund approved in principle” and “cash actually arrives” are two different milestones. (cbp.gov)is not Treasury opening a fresh portal on May 11. It is CBP’s refund machinery, already partly live, finally starting to turn a Supreme Court ruling into payments. (cbp.gov)
