How much do remaining tariffs cost consumers after emergency powers struck down?
Core argument: The Budget Lab estimates that without IEEPA tariffs, U.S. consumers face an average effective tariff rate of 9.1%, the highest since 1946 excluding 2025, versus 16.9% had IEEPA tariffs remained in effect.
The Budget Lab estimates the effects of all US tariffs and foreign retaliation implemented in 2025 after the decision by the Supreme Court of the United States that President Trump exceeded his authority to invoke the 1977 International Emergency Economic Powers Act (IEEPA) to impose reciprocal tariffs. Without IEEPA tariffs, consumers will face an overall average effective tariff rate of 9.1%, which remains the highest since 1946 excluding 2025. (If IEEPA tariffs had been allowed to stay in effect, this figure would have been 16.9%.) All tariffs to date as of February 2026 are projected to raise about $1.2 trillion over 2026-35, though slower economic growth reduces revenues and brings the net dynamic revenue to $1 trillion. (With IEEPA, these figures would be more than twice as large.) The economic implications of the SCOTUS decision are complicated by two major factors. First, in the short-term, firms will be aggressively seeking refunds on tariffs paid in 2025, which has large revenue effects and uncertain distributional effects. Second, the current Administration has stated its intent to replace IEEPA tariffs with tariffs using other authorities, but there remain timing and other questions regarding these steps.
