Federal Judge Orders Massive Tariff Refunds Totaling Up to $182 Billion

A federal judge has directed the U.S. government to start issuing refunds for Trump's emergency tariffs that were ruled illegal by the Supreme Court. Economic analysts estimate these refunds could reach between $168 billion and $182 billion for importers nationwide.

WASHINGTON – Following a Supreme Court decision in late February that declared President Donald Trump’s emergency tariffs unlawful, a federal judge has mandated that the U.S. government commence refund payments that could total as much as $182 billion, according to budget experts.

Senior Judge Richard Eaton of the Court of International Trade issued the directive on Wednesday, requiring the Customs and Border Protection agency to present preliminary plans by Friday for a comprehensive refund system designed to prevent thousands of separate legal challenges.

During Wednesday’s court proceedings, Eaton emphasized the government’s obligation, stating: “I want to make it clear to the customs service that they have to refund any money that was unlawfully collected.”

However, the specific process for distributing these refunds remains uncertain at this time.

Research teams from major universities have provided varying calculations of the potential refund amounts based on tariff data and projections.

The Penn Wharton Budget Model at the University of Pennsylvania projects that CBP accumulated as much as $182 billion in total revenue from tariffs enacted under the International Emergency Economic Powers Act spanning from February 4, 2025, through February 23, 2026.

Their analysis, conducted specifically for Reuters, utilized a comprehensive forecasting system examining tariffs across approximately 11,000 product classifications from 233 nations worldwide.

Using an alternative calculation method, Penn-Wharton researchers arrived at a secondary estimate of roughly $177 billion in IEEPA tariff collections. This figure was determined by analyzing what percentage of overall U.S. Treasury customs income consisted of IEEPA tariffs through December 14, then projecting that same proportion to subsequent customs revenues.

According to the most recent CBP data from December 14, IEEPA tariff assessments totaled $133.5 billion.

Meanwhile, Yale University’s Budget Lab calculated IEEPA tariff collections at $168 billion through February 19, using forward estimates based on the December 14 CBP assessment figures, placing their projection somewhat below Penn-Wharton’s estimates.

Yale researchers also determined that by January 2026, all Trump-era tariffs implemented in 2025 increased average inflation-adjusted customs revenue by $194.8 billion compared to the 2022-2024 baseline. This encompasses a $174.7 billion increase throughout 2025 and an additional $20.1 billion in January 2026 alone.

The Yale team calculated that before the Supreme Court struck down the IEEPA tariffs, the effective U.S. tariff rate had reached 9.9%.

Following the high court’s decision, the Trump administration implemented an interim 10% worldwide tariff using Section 122 of the Trade Act of 1974, with plans to increase it to 15%.

The Committee for a Responsible Federal Budget projects the 10% tariff will produce approximately $35 billion in fresh net revenue during the 150-day period permitted under current law, potentially reaching $50 billion at the 15% level.

Any extension would require Congressional authorization, but if approved or replicated through alternative tariff mechanisms, CRFB estimates decade-long revenue could surpass $900 billion at 10% or reach $1.3 trillion at 15%.

According to CRFB analysis, the Section 122 tariffs would compensate for more than half the revenue loss from the Supreme Court ruling at 10%, and over three-quarters at 15%.

Penn Wharton’s projections for 10-year Section 122 revenue are slightly higher, estimating $1.51 trillion assuming a 15% rate, with potential 2026 revenue of $136 billion if maintained for a full year.
