U.S. Tariff Revenue Falls $100 Billion Short of Expectations

U.S. tariff revenues are significantly lagging, falling about $100 billion short of the anticipated figures set by the White House, according to a report from Pantheon Macroeconomics. Earlier this year, Treasury Secretary Scott Bessent forecasted that tariffs could generate “well over half a trillion, possibly nearing a trillion-dollar figure,” yet current projections indicate customs and excise taxes will total only about $400 billion.

The shortfall is largely due to an average effective tariff rate (AETR) substantially lower than predicted. Present estimates place the AETR at merely 12%, compared to nearly 20% anticipated in spring forecasts. Recently, even the Congressional Budget Office adjusted its estimates downwards from 20.5% to 16.5%. Economists are pointing to three primary reasons for this decline in tariff collections.

1. Decrease in Imports from China and Shift in Trade Routes

Imports from China have seen a decline of 30%, reducing the Chinese share of total imports from 13% to 9% this year. Companies are increasingly routing goods through Vietnam, which has increased its share of imports from 4% to 6%, especially in sectors such as game consoles, televisions, and apparel. These items incur a 20% tariff, significantly lower than the nearly 50% levied on Chinese imports, further contributing to the revenue deficit.

2. Enhanced Compliance with USMCA

Goods from Canada and Mexico are entering the U.S. under the USMCA trade agreement at rates surpassing initial expectations. While the White House had estimated that 38% of Canadian and 50% of Mexican imports would remain tariff-free, the actual AETRs in August stood at only 5% for both nations. More businesses are demonstrating the origins of their products to obtain tariff exemptions, which skews the revenue projections from the White House.

3. Increased Imports of Tariff-Exempt AI and High-Tech Goods

Imports of advanced computing and AI equipment—classified as “automatic data processing machines”—account for 9% of total imports, a significant rise from 4% last year. This increase in tariff-exempt high-tech products hides a 10% drop in other imports, which contributes to lowering the overall effective tariff rate.

Economists suggest that the current scenario may be temporary, with firms potentially delaying imports to reduce inventory ahead of expected legal changes. If tariffs persist, volumes of imported goods subject to tariffs may bounce back next year, leading to a slight increase in revenue, though likely still underwhelming compared to initial forecasts.

Consumer and Economic Impact

While tariff revenues fall short, the burden is falling on American consumers. Tariffs act as an indirect tax on imports, with estimates indicating they will cost U.S. consumers approximately $29 billion this holiday season. High tariffs are also adding to inflation, potentially increasing core inflation by 0.8 percentage points by 2026, partially reversing a year’s worth of disinflation benefits.

The combination of disappointing revenues and rising consumer costs underscores the intricate trade-offs inherent in the U.S. tariff system.
