The non-partisan Congressional Budget Office said President Donald Trump’s recently enacted tax-and-spending package—the so-called Big Ugly Law—will reduce annual resources for the poorest 10 percent of U.S. households by roughly $1,200 while boosting those of the wealthiest 10 percent by about $13,600. CBO’s distribution tables show the measure cutting the bottom decile’s resources by 3.1 percent and lifting the top decile’s by 2.7 percent, an imbalance the agency called unprecedented for major budget legislation in the past four decades. Middle-income households are forecast to gain between $800 and $1,200 a year. The shift stems from a combination of extended and expanded tax breaks—including broader 2017 income-tax cuts, a higher cap on state-and-local deductions and a larger child credit—and substantial trims to safety-net programs. New work requirements are expected to drop average monthly participation in the Supplemental Nutrition Assistance Program by 2.4 million people, while changes to Medicaid could leave about 10 million Americans without health coverage by 2034. CBO estimates the law will widen federal deficits by $3.4 trillion over the next decade. Republican leaders argue the tax relief will spur growth and question the agency’s methodology, while Democratic lawmakers point to the report as evidence that the legislation shifts wealth upward and erodes the social safety net ahead of the 2026 midterm elections.
