A 6-3 Supreme Court ruling on February 20, 2026, struck down the tariffs the Trump administration imposed under the International Emergency Economic Powers Act, and the Penn Wharton Budget Model puts the resulting refund liability at as much as $175 billion. That number lands squarely on federal finances rather than on the tens of millions of American shoppers who spent more than a year paying tariff-inflated prices on imported goods. Under Customs and Border Protection rules, only the importer that filed the paperwork and paid the duty can claim a refund, leaving the eventual size of any consumer benefit up to companies that have made no such commitment.
Why the Refund Money Goes to Importers, Not Shoppers
The distinction hinges on a specific legal status: importer of record. Retailers, manufacturers and other businesses that directly imported goods and paid the assessed IEEPA duty are the parties Customs and Border Protection recognizes as eligible to seek money back. A retailer that merely priced tariff costs into a shelf tag, without ever filing the customs paperwork itself, is not automatically entitled to anything, and a household that paid the marked-up price at checkout has no filing right at all, because no customs transaction was ever made in that household’s name.
Penn Wharton’s own account of the ruling notes that the decision did not order refunds outright; it simply removed the legal basis for the tariffs and opened the door to claims. Importers generally have 180 days after a shipment is “liquidated,” the point at which Customs and Border Protection finalizes the duty owed, to file a protest and request money back, and that window runs separately for each entry rather than on a single fixed date. That staggered structure is why the refund process is unfolding over months instead of arriving as one lump-sum correction.
Whether any of that money reaches a shopper is left entirely to the businesses that receive it. Customs and Border Protection can only issue a refund to the recognized importer of record, and once a company has the money, it can keep it as recovered cost, apply it to past losses, or lower future prices, with nothing in the ruling or the executive order that revoked the tariffs requiring any of the three. Because the case addressed only the legality of the tariff authority and not the commercial behavior of the companies that paid it, the $175 billion projection describes money moving from the federal government to businesses, not from businesses to households.

Customs Has Already Repaid $100 Billion of What It Owes
The refund process is no longer theoretical. A court filing made public in early August 2026 showed that the federal government had already returned more than $100 billion of the tariffs collected under the IEEPA authority, roughly 60% of what it owes importers on the record. That progress puts the Penn Wharton estimate well within range rather than a worst-case outlier, and it shows real money moving months before the final total is settled.
The scale of that repayment reflects how large the underlying revenue stream had become. Penn Wharton’s tracking shows cumulative IEEPA tariff collections reaching roughly $164.7 billion by January 2026, with IEEPA duties growing to represent just over half of all customs duties collected that month, up from essentially nothing at the start of 2025. A ruling that erased the legal basis for a revenue stream of that size was always going to force a refund fight measured in the tens of billions rather than one the Treasury could absorb quietly.
The duties now being refunded were not spread evenly across trading partners. IEEPA tariffs applied only to Chinese imports when they began in February 2025, expanded to cover goods from Canada and Mexico by March 2025, and broadened again in April 2025 into the administration’s “reciprocal” tariff structure covering imports from every trading partner. China’s earlier and longer exposure means Chinese-import specialists carry a disproportionate share of both the revenue already collected and the refund claims now moving through Customs and Border Protection.
For older Americans who financed everyday purchases at prices inflated by the tariffs, the $100 billion already refunded is a reminder of how the money is moving rather than a sign that any of it is returning to them personally. The duties were built into the price of imported groceries, appliances and other household goods for more than a year, and the businesses that imported those goods, not the households that ultimately paid the higher prices, are the accounts Customs and Border Protection is crediting.
The 180-Day Filing Window Now Shaping Who Gets Paid
Because the 180-day filing window is tied to each shipment’s own liquidation date rather than to the date of the Supreme Court’s ruling, the refund process will not close on a single deadline. Shipments that liquidated earliest during the roughly 14 months IEEPA tariffs were in effect carry the earliest filing deadlines, while importers still working through paperwork on later 2025 shipments have more time left before their own 180-day clock runs out.
The mechanics of that process have continued to be worked out case by case rather than settled by a single order, since the Supreme Court’s decision and the executive order that revoked the tariffs both left the refund procedure to the U.S. Court of International Trade. Government attorneys and importer groups have kept negotiating details such as how partial refunds are credited and how calculation disputes are resolved, which helps explain why, more than six months after the ruling, only a portion of the total owed has been repaid rather than the full amount moving at once.
The practical effect is that the $175 billion figure functions as a ceiling on what could eventually be returned, not a guarantee of what will be, since the final number depends on how many eligible importers file within their individual windows and how the Court of International Trade resolves the disputes still pending. Penn Wharton’s own analysis is explicit that the ruling did not order immediate refunds, which leaves both the ultimate size of the payout and any decision by importers to share it with customers unresolved even as the government works through the $100 billion already on the books.
