US Tax Policy in 2026: A Realistic Outlook on Legislative Gridlock

Watch on YouTube

The US tax landscape is marked by significant legislative paralysis, and meaningful tax reform is unlikely before 2028. The upcoming elections, while potentially shifting political power, will not alter this fundamental reality due to the structural design of the US governance system.

The US Governance Reality

To understand US tax policy, one must first understand the US system of governance, which is fundamentally designed to make change difficult. The US is not a parliamentary system; it has three independent branches of government: executive, legislative, and judicial. Legislation, including tax laws, must pass both the House of Representatives and the Senate in identical form before reaching the President, who can veto it. This system of “checks and balances” intentionally requires broad consensus to enact change. The executive branch, including the President, has surprisingly little direct influence on tax legislation, which is primarily driven by Congress.

A Stalled Legislative Agenda

Currently, the Republican Party holds a trifecta with the presidency and slim majorities in both houses. However, these majorities are fragile, and the upcoming midterm elections are likely to shift the balance of power significantly, with the House widely expected to flip to Democratic control. Regardless of the outcome, meaningful tax reform is unlikely before 2028. Even if both houses were to pass legislation, the President would retain veto power, and overriding a veto requires a two-thirds supermajority—a nearly impossible threshold.

Looking Ahead to 2028 and Beyond

Looking further ahead, a potential Democratic trifecta in 2028 could reignite tax policy debates. If that scenario unfolds, corporate and individual tax rates would very much be on the agenda. The United States, as one of the few countries without one, may eventually have to consider implementing a value-added tax (VAT). However, any such changes remain speculative and contingent on a significant political realignment after the next presidential election.

The Broader Gridlock on International Tax Agreements

The paralysis extends beyond domestic legislation. The US treaty program has been in serious trouble for years, long before the current administration. A single senator has effectively blocked the approval of nearly all tax treaties since 2010 due to opposition to information exchange provisions. This individual holds significant power to stall the entire treaty approval process, and there is no immediate prospect of this changing. The business community has only managed to push through a few protocols with significant effort, a level of mobilization unlikely to be repeated for all pending agreements.

Conclusion

The US tax environment is in a state of legislative and treaty gridlock. Companies and tax professionals should plan for the status quo to persist for the next several years. The structural hurdles of the US governance system, combined with political dynamics, mean that major changes are unlikely before 2028. The path to meaningful tax reform requires a level of political consensus and legislative cooperation that appears out of reach in the current environment.
