President Donald Trump's tariff policies are turning into a massive revenue generator for the federal government, but the economic trade-offs are becoming increasingly clear. According to a Tax Foundation report released last Friday, these tariffs are projected to bring in $2 trillion in revenue between 2026 and 2035 on a conventional basis—though that figure drops to $1.6 trillion when you account for their drag on economic growth.
Here's how the numbers break down: Section 232 tariffs are expected to raise $635 billion over the decade, while tariffs imposed under the International Emergency Economic Powers Act (IEEPA) could generate another $1.4 trillion. Collections in 2025 will be lower simply because the tariffs weren't in effect for the full year.
But when you factor in the economic damage—slower growth, reduced business activity, retaliatory measures from other countries—those revenue projections shrink considerably. On a dynamic basis, Section 232 tariffs are expected to raise $490 billion, and IEEPA tariffs about $1.1 trillion. Retaliatory tariffs from trading partners further reduce the 10-year haul by $136 billion.
The Household Tax Nobody Voted For
For 2026, the Tax Foundation projects Trump's tariffs will increase federal tax revenues by $171.1 billion, representing about 0.54% of GDP. That makes it the largest tax increase since 1993. If courts permanently block the IEEPA tariffs, though, the remaining measures would only generate $53.8 billion in revenue that year—roughly 0.17% of GDP.
And someone has to pay those tariffs. The average U.S. household is looking at a $1,000 tax increase in 2025 and $1,300 in 2026 as companies pass along higher import costs. If the IEEPA tariffs get blocked, that 2026 increase would drop to around $400.
Record Collections, But Momentum Is Slipping
In 2025, customs duties generated $264 billion in federal revenue, combining both new and existing tariffs. After accounting for reduced income and payroll tax collections caused by economic slowdown, the net gain from new tariffs is estimated at $132 billion.
Customs and Border Protection data shows the U.S. collected over $200 billion in tariff revenue between January 20 and December 15, 2025. But here's the concerning part: November saw the first month-over-month decline in tariff revenue since tariffs ramped up in April, according to Treasury Department data. That's raising questions about whether the revenue surge is sustainable.
Investment Claims and Legal Questions
Trump has repeatedly claimed his tariff policies have triggered an unprecedented wave of investment into the U.S. economy, with companies choosing to build domestically rather than face steep import duties. "Because of the tariffs, we've taken in more than $18 trillion," he said.
The president has framed his tariff strategy as essential to national security, which is why many of the measures were imposed under the IEEPA. Those particular tariffs are now under Supreme Court review, and Wall Street is watching the case closely.
Meanwhile, Supreme Court Justice Ketanji Brown Jackson recently expressed doubt about whether courts could actually force Trump to refund the recently imposed tariffs, pointing to the constitutional complexity and numerous intricate legal issues involved in such a scenario.
