• The White House challenges CBO's deficit projections for the "One Big Beautiful Bill," arguing it ignores tariff revenues and economic growth.
  • Navarro claims reciprocal tariffs could generate $2.3T-$3.3T over a decade, potentially turning the bill into a surplus.
  • Analyses diverge sharply, with Tax Foundation projecting $4.1T revenue loss while JCT shows double-digit tax cuts for middle earners.

Clashing Fiscal Projections

The White House escalated its criticism of the Congressional Budget Office's preliminary assessment of the Republican tax package, calling the nonpartisan scorekeeper's methodology "a shoddy assumption" that disregards two key revenue streams. Senior trade advisor Peter Navarro told reporters the CBO "refused to account" for an estimated $2.3 trillion to $3.3 trillion in projected tariff revenues from the administration's new 10% baseline global tariff structure.

"When you factor in the External Revenue Service collections and dynamic scoring from accelerated growth, this bill could actually produce a $2 trillion surplus under realistic assumptions," Navarro asserted. The comments came hours after the CBO indicated the legislation would substantially increase deficits, though it hasn't released complete distributional analysis.

The Numbers War

Discrepancies between analyses reveal starkly different premises. The Joint Committee on Taxation found middle-income households ($30K-$80K) would see tax bills drop ~15% by 2027, while millionaires' liabilities would fall 8.6%. But these projections don't incorporate spending cuts that could disproportionately affect lower earners.

The Tax Foundation's model, incorporating macroeconomic effects, still showed $4.1 trillion in conventional revenue losses through 2034 despite predicting 0.8% GDP growth. A White House official, speaking anonymously, countered that "static scoring is what got us $34 trillion in debt" and insisted tariff revenues would fundamentally alter the equation.

Legislative Clock Ticking

With the House already passing the amended bill on May 22, attention turns to Senate negotiations where the SALT deduction expansion remains contentious. Banking Committee staffers confirmed the CBO is expediting its final cost estimate ahead of a potential late-June vote. Meanwhile, Treasury has begun preliminary work on implementing the proposed External Revenue Service, though congressional appropriators haven't yet authorized funding.

One Senate Finance aide noted the unusual circumstance of debating a tax bill where "the pay-fors might literally come from another country" through tariffs. Whether those revenues materialize—and whether the CBO will ever score them—remains the central fault line as the bill advances.
