U.S. to start refunding invalidated Trump‑era tariffs on May 11, tells federal court

Tariff refunds are finally about to become real money. After months of court fights and customs-system work, the U.S. told a federal trade court that the first refunds for invalidated Trump-era tariffs should start going out around May 11. That matters because a lot of companies paid the government first and argued about the cost later. Now the legal question is mostly settled, but the commercial question is just starting. ### Which tariffs are we talking about? These were the broad import duties Trump imposed under the International Emergency Economic Powers Act, or IEEPA. That law is built for emergencies, not for permanent economy-wide tariffs. In February, the Supreme Court said the administration had overreached, which blew up the legal basis for those duties and opened the door to mass refunds. A March order from the Court of International Trade then said businesses that paid them are entitled to get that money back. (bakertilly.com) ### What changed this week? The new piece is timing.
