How much revenue would sector-specific tariffs raise, and at what output cost?
Core argument: The Budget Lab estimates a 25% tariff on all automotive, pharmaceutical, and semiconductor imports would raise the average effective tariff rate by 5.2 percentage points, to its highest level since 1965.
The Budget Lab modeled a 25% tariff on all automotive, pharmaceutical, and semiconductor imports. The illustrative proposal is the equivalent of a rise in the average effective tariff rate of 5.2pp, bringing it to its highest level since 1965. Were it to remain in place, the policy would raise $980 billion over 2026-35 conventionally-scored without retaliation (0.3% of GDP on average over 10 years), and $900 billion with retaliation (0.2% of GDP). The proposal reduces the short- and long-run level of US real GDP. In calendar year 2025, real GDP growth is 0.2pp lower without retaliation and 0.3 percentage point with. In the long-run, US output is still -0.8 to -0.12% lower without retaliation and almost twice as much with. That’s the equivalent of the US economy being permanently smaller by $23-$35 billion annually in 2024 dollars.
