US are at risk of being refunded if the U.S. Supreme Court rules against levies imposed under the International Emergency Economic Powers Act (IEEPA) by President Donald Trump. This estimate, which arrives as the court is expected to rule on the legality of the measures as early as this week, highlights a significant fiscal risk that could materially reduce federal tariff receipts and disrupt government cash management.The analysis, produced using a product- and country-level tariff forecasting model, indicates that the scale of potential refunds is large enough to exceed certain federal departmental outlays. Specifically, the at-risk amount of more than $175 billion surpasses the combined fiscal 2025 outlays of the Department of Transportation and the Department of Justice. The report also notes the figure is significant when compared to daily and monthly customs receipt measures. Such a massive outflow would have immediate operational implications for U.S. Customs and Border Protection and the U.S. Department of the Treasury, affecting both cash balances and federal borrowing plans.
