President Trump's promise to send $5,000 checks to every adult citizen would carry a price tag of $1.25 trillion, a figure that dwarfs the revenue generated by his new tariffs, according to an analysis published by the Tax Foundation. The proposal, announced at the Republican National Convention in Dallas and contingent on Republicans keeping control of both chambers of Congress in the midterms, lacks specifics on income restrictions or eligibility limits. Vice President JD Vance defended the plan by pointing to tariff revenue as a funding source, but the numbers tell a different story.

Customs duties collected by the federal government jumped from $79 billion in calendar year 2024 to $264 billion in 2025 after the Trump administration rolled out multiple waves of new tariffs, the report notes. However, recent months have seen collections drop and even turn negative as Washington refunds tariffs that the Supreme Court struck down as illegal. Once those swings stabilize and assuming current policies remain unchanged, the Tax Foundation estimates Trump's tariffs will bring in roughly $125 billion in net revenue for 2027 and $1.4 trillion across the decade from 2026 through 2035. Net revenue falls short of gross collections for two key reasons: the tariffs suppress import volumes, which reduces income from pre-existing duties, and every dollar raised through tariffs shrinks the tax base for income and payroll levies, cutting into what those sources would otherwise generate. Sending a $5,000 payment to the 250 million voting-age adults would require the full amount upfront, and the federal government is already facing a projected budget shortfall of nearly $1.9 trillion in fiscal year 2027.

The analysis finds that tariff revenue in 2027 would cover only about one-tenth of what the dividend would cost, meaning it would take almost ten years of tariff collections to pay for a single round of checks. Even trimming the program by adding income caps or other restrictions wouldn't solve the fundamental mismatch, the report states, and spending upward of $1 trillion on a one-time payment program would push the deficit close to $3 trillion despite the new tariff income. Senior Economist Erica York, who authored the analysis, points out that such a program would be misguided when deficits are already massive and inflation is running above the Federal Reserve's 2 percent target.

The report argues that a deficit-funded dividend of this scale would send a signal to financial markets that the United States isn't serious about fixing its fiscal problems. It would risk pushing interest rates higher, add fuel to inflationary pressures, and make worse the very issues the proposal claims to address. The mechanisms are straightforward: pumping more than a trillion dollars into the economy when it's already running hot would increase demand without expanding supply, driving up prices and forcing the Fed to tighten monetary policy further. York concludes that Americans would benefit more if the administration scrapped the tariffs altogether, since they're placing a burden on businesses and workers across the country. The bottom line is clear: the math doesn't work, and the economic consequences could backfire.
