The Congressional Budget Office has determined that the Senate Republican tax bill would increase the national debt by about $3.3 trillion over the next ten years and leave an estimated 11.8 million more Americans without health insurance by 2034.
Under the proposal, roughly $3.8 trillion in tax cuts enacted during the Trump administration would be extended. The measure funds those extensions by reducing spending on programs such as Medicaid and certain food assistance initiatives. Republicans remain divided, however, over the size and scope of the spending reductions needed to pay for the tax changes.
Republican lawmakers and aides have pushed back against the CBO’s projection, presenting alternative analyses that they say show the legislation would shrink the deficit by about $500 billion over the same period. Democrats have criticized those alternative figures, accusing Republicans of using overly optimistic or selective assumptions to reach a more favorable result.
The bill cleared a procedural hurdle in a closely contested 51-49 vote after extensive negotiations, but the narrow margin highlights the political challenges ahead. Lawmakers face pressure from conservative members seeking deeper spending cuts and from moderates and Democrats warning about the potential impact on health coverage and safety-net programs.
Key points of contention include the timing and scale of cuts to Medicaid and nutrition programs, which proponents argue are necessary to offset the cost of extended tax provisions, and opponents say would harm vulnerable populations. The differing budget estimates reflect disagreements over economic growth assumptions, baseline calculations, and which policy changes to include in scoring.
As the legislative process continues, further amendments and negotiations are likely. Lawmakers will need to reconcile competing budget estimates and policy priorities before the bill can advance, while watchdogs and advocates on both sides of the issue continue to weigh in on the bill’s potential fiscal and social consequences.
