U.S. Tariff Revenues Fall $100B Short Despite High Hopes

U.S. tariff revenues are underperforming sharply, generating roughly $100 billion less than the White House had expected, according to an analysis by Pantheon Macroeconomics. While Treasury Secretary Scott Bessent predicted earlier this year that tariffs could raise “well over half a trillion, maybe toward a trillion-dollar number,” recent data suggests annualized customs and excise taxes will reach only $400 billion.

The gap stems from an average effective tariff rate (AETR) far below projections. Current estimates place the AETR at just 12%, well below the nearly 20% expected in spring. Even the Congressional Budget Office revised its forecast down to 16.5% from 20.5% last month. Economists identify three key reasons behind the lower-than-expected tariff collection.

1. Plunge in Imports from China and Trade Rerouting

U.S. imports from China have fallen by 30%, dropping China’s share of total imports to 9% from 13% in 2024. Companies are rerouting goods through Vietnam, whose share of imports has risen from 4% to 6%, driven by game consoles, TVs, and clothing. These goods carry a 20% tariff, below the nearly 50% applied to Chinese imports, contributing to the revenue shortfall.

2. Stronger-than-Expected USMCA Compliance

Goods from Canada and Mexico are entering the U.S. under the USMCA trade agreement at higher rates than initially projected. While the White House estimated 38% of Canadian and 50% of Mexican imports would be tariff-free, realized AETRs in August were only 5% for both countries. Businesses are increasingly proving the origin of their products to claim tariff exemptions, skewing White House revenue calculations.

3. Surge in Tariff-Exempt AI and High-Tech Imports

Imports of advanced computing and AI equipment, categorized as “automatic data processing machines,” now account for 9% of total imports, up from 4% last year. This surge in tariff-exempt high-tech goods masks a 10% drop in other imports, further lowering the overall effective tariff rate.

Economists note that this could be a temporary factor, with firms delaying imports to deplete inventories ahead of potential legal changes. Should tariffs remain, import volumes subject to tariffs may recover next year, slightly increasing revenues—but likely still below initial expectations.

Impact on Consumers and the Economy

While tariff revenues fall short, American consumers are bearing the cost. Tariffs act as a hidden tax on imports, with estimates suggesting they will cost U.S. shoppers around $29 billion this holiday season. High tariffs also contribute to inflation, potentially adding 0.8 percentage points to core inflation in 2026, partially offsetting a year’s worth of disinflation gains.

The combination of lower-than-expected revenues and higher consumer costs highlights the complex trade-offs of the U.S. tariff regime.
