Despite record-breaking tariff revenue in July 2025, the U.S. budget deficit still climbed 20% compared to last year, according to Treasury Department data.
While customs revenue surged 273% (or $21 billion) due to President Trump’s import taxes, federal spending continues to outpace government revenues. The deficit increase is driven by rising interest payments on the $37 trillion national debt and cost-of-living adjustments to Social Security.
Although the Congressional Budget Office estimates tariffs could reduce deficits by $2.8 trillion over 10 years, economists warn this comes with trade-offs including slower economic growth and higher inflation.
