Republicans lay groundwork for ‘total tax cliff’ at end of Trump’s term

Congressional Republicans are considering a tax plan that would make the 2017 Trump tax cuts permanent while allowing additional tax breaks for working-class Americans, seniors, and families to expire at the end of 2028, creating a potential "tax cliff." Budget hawks and some senators have expressed concerns about the economic impact and political implications of this approach, particularly the potential for increased deficits and the temporary nature of certain tax cuts. While the Senate aims to make the 2017 tax cuts permanent, the fate of the expiring cuts remains uncertain, with some senators open to discussing their future.

Analysis

Congressional Republicans are structuring a tax plan to make the 2017 Tax Cuts and Jobs Act (TCJA) permanent, as most of its provisions are set to expire at the end of the current year, while new tax relief measures targeted at working-class Americans, seniors, and families are slated for expiration at the end of 2028. These expiring provisions include enhancements to the standard deduction, the deduction for seniors, the child tax credit, and the cancellation of taxes on tips, overtime pay, and car loan interest. This strategy is creating what budget hawks and some Republican members, such as Rep. Chip Roy, describe as a "total tax cliff" of approximately $1.5 trillion in expiring cuts, potentially becoming a significant issue in future presidential races and characterized by some as a fiscal "gimmick." The House-passed version of this plan has raised considerable fiscal alarms, with the Congressional Budget Office (CBO) projecting it would add $2.4 trillion to national deficits over the next decade, potentially increasing to $3.0 trillion when factoring in an estimated $551 billion in additional interest costs. Economic forecasts for the plan are modest; the Joint Committee on Taxation (JCT) estimates a marginal increase in long-term economic growth from 1.83% to 1.86%, while one JCT model indicates a 0.9% reduction in U.S. capital stock over the budget window, contributing to an average 0.1% decrease in overall economic output. These fiscal and economic projections have reportedly "rattled financial markets and spurred a sell-off in the bond market." Furthermore, distributional analyses from the JCT suggest the bill disproportionately benefits higher earners, with, for example, half of the passthrough deduction (worth over $200 billion in 2022) accruing to the top 1% of taxpayers. While the Senate may introduce substantial changes, leveraging a more accommodating budget baseline, key senators like Ron Johnson have expressed reservations about temporary tax policies, preferring permanence for measures deemed beneficial. The prevailing sentiment surrounding these legislative efforts is "strongly negative," reflecting the significant uncertainty and concerns about the plan's economic and fiscal sustainability.

Key Decisions for Investors

• Investors should closely monitor the legislative developments, particularly Senate modifications to the proposed tax plan, as the "strongly negative" sentiment and projected minimal net economic growth, including a potential 0.1% decrease in output according to one JCT model, could heighten market volatility and necessitate adjustments to sector allocations.
• The creation of a new "tax cliff" around 2028, involving an estimated $1.5 trillion in expiring tax provisions combined with a CBO-projected $3.0 trillion increase in the deficit over the next decade, introduces considerable medium-term fiscal uncertainty; this warrants careful assessment for portfolio positioning, especially in interest-rate sensitive assets and sectors affected by fiscal stability, particularly in light of reported bond market reactions.
• Given the internal Republican debate on the permanence of certain cuts and the plan's distributional consequences, which favor higher-income individuals and may fuel political contention, investors should anticipate ongoing policy uncertainty and evaluate the potential for future legislative reversals or economic instability leading up to the 2028 expiration and beyond.
