The Treasury just posted a number that turned heads. In June 2025, the federal government collected $26.6 billion in tariff revenue. That’s up from $22.2 billion in May and more than quadruple the $6.3 billion recorded in June 2024. The spike helped deliver a $27 billion budget surplus for the month, the first surplus since 2017. The fiscal year-to-date deficit still sits at $1.34 trillion, but the June print shows what happens when trade policy turns into a revenue engine.
The tariff haul came from across-the-board 10% duties imposed in April, plus a menu of reciprocal tariffs ranging from 25% to 50% on countries with trade barriers against the U.S. Those rates are set to climb again on August 1. Canada will face 35%. Brazil gets 50%. Japan, South Korea, and Thailand are on the list. The letters went out. The clock is ticking.
Tariffs now account for roughly 5% of total federal revenue. That’s up from 2% historically. Customs duties have become the fourth-largest revenue source behind individual income taxes, corporate taxes, and payroll taxes. Treasury Secretary Scott Bessent told the Cabinet last week that tariff collections could hit $300 billion by year-end. The Congressional Budget Office projects $2.8 trillion in tariff revenue over the next decade.
The surplus wasn’t just receipts. Spending dropped by $187 billion in June. That came from cuts to federal workforce, agency budgets, and discretionary outlays under the Department of Government Efficiency. Interest payments on the $36 trillion national debt still hit $84 billion for the month. That’s the second-largest line item behind Social Security.
The tariff model is now baked into the budget. The Big Beautiful Bill passed in early July includes tax cuts funded by projected tariff revenue. The administration is betting that trade duties can offset spending and reduce the deficit. The numbers from June suggest that bet is starting to pay out.
