They say death and taxes are life’s only certainties — but according to President Donald Trump, a significant part of the latter could be on the chopping block.
Speaking to U.S. military service members in November, Trump floated the idea of eliminating income taxes entirely, funded by what he described as massive new tariff revenues (1).
Trump noted that tariffs have pulled in “hundreds of billions” in duties, and went on to claim, “Next year it’ll be a trillion dollars or more.” It was unclear whether this prediction refers solely to tariff revenue, or if it would also include money generated from the relocation of manufacturing operations — like cars — to U.S. soil.
Regardless, the president seemed convinced that tariffs would be a big win for the American people in the next few years.
“I think we’ll substantially be cutting and maybe cutting out completely, but we’ll be cutting income tax,” he said. “Could be almost completely cutting it because the money we’re taking in is going to be so large.”
It’s a bold proposal, especially given that income tax is the federal government’s single largest source of revenue.
In fiscal year 2025, the federal government collected $2.656 trillion in individual income taxes — about 50.7% of Uncle Sam’s total $5.235 trillion in receipts. By comparison, corporate income taxes brought in $452 billion and tariff revenue from custom duties totaled just $195 billion (2). That’s still a far cry from Trump’s trillion dollar claim.
Critics quickly pointed out the gap.
Economist Erica York of the Tax Foundation said the math simply doesn’t work — nor would Trump’s vision be easy to implement.
“Mathematically impossible, plus any income tax cuts would require Congress,” York wrote on X (3).
“To replace the roughly $2 trillion of revenue raised by the individual income tax with tariffs would require astronomically high tariff rates. And those rates would shrink imports, making it impossible to generate enough revenue to replace the income tax (4).”
It’s also worth noting that even with income tax revenue, the federal government still spent far more than it brought in: $5.235 trillion in total receipts versus $7.010 trillion in outlays, leaving a $1.775 trillion deficit in fiscal 2025.
