Trump Has Served Up the Largest U.S. Tax Increase Since 1993

[Yo_Mama_Been_Loggin]

In 2025, President Donald Trump imposed the largest U.S. tax increase since 1993, measured as a share of GDP. It did not come through income brackets or payroll deductions. It came through tariffs — raising the effective tariff rate to its highest level since 1946 and costing the average household about $1,000 last year alone. The modeled long-run economic drag approaches $200 billion annually. The tariff regime is structural. The costs are no longer theoretical.

In the aftermath of World War II, the United States began dismantling the high-tariff regime that had defined the interwar period. The 1947 General Agreement on Tariffs and Trade marked the beginning of a multi-decade shift toward trade liberalization as a central pillar of American economic policy. Over the following decades, tariffs receded as a source of federal revenue and rarely shaped macroeconomic outcomes.

That posture has reversed.

As of early 2026, the average effective tariff rate on U.S. imports — measured as duties collected relative to total import value after behavioral adjustments — stands near 9.9 percent. The import-weighted applied rate — reflecting statutory tariff schedules across products and trading partners — is approximately 13.5 percent. By historical comparison, those levels are the highest observed in the postwar era.
