US 'Tax The Rich' Initiatives on Ballot in California and Washington in November 2026

Critical tax policy decisions are poised to be made by voters in California and Washington states in the November 2026 elections. These ballot initiatives highlight the ongoing national debate surrounding taxation of the wealthy and their potential fiscal implications for state budgets across the United States.

In California, Proposition 40, known as the "Billionaire Tax Act," proposes a one-time 5% wealth tax on the accumulated net worth of individuals and trusts residing in the state as of January 1, 2026, with assets exceeding $1 billion. Proponents aim to generate an estimated $100 billion from this tax, earmarked for state-funded healthcare, education, and food assistance programs. The initiative is largely backed by labor unions. Conversely, Washington state voters will consider Initiative 645 (I-645), which seeks to repeal a recently enacted 9.9% income tax on household incomes exceeding $1 million, and generally prohibit income taxes. This income tax, established by Senate Bill 6346 (SB 6346), was signed into law on March 30, 2026, with collections slated to begin in 2029. The "Let's Go Washington" group is sponsoring I-645, advocating for the repeal of the tax and the re-establishment of a broader income tax ban within the state.

Concerns about the economic ramifications of such tax measures are significant. Critics of California's proposed wealth tax, including Governor Gavin Newsom, argue it could trigger capital flight from the state and may not generate the projected revenue, potentially even leading to a net reduction in overall state revenue. Some analyses suggest that the actual effective tax rate could be substantially higher than 5% due to aggressive valuation methodologies. Globally, many developed countries have repealed wealth taxes due to challenges such as low revenue generation, high administrative costs, and the outflow of wealthy individuals and their capital. S&P Global Ratings emphasizes that a state's creditworthiness is influenced by its ability to manage revenue volatility following tax changes.

These developments are set against a broader US economic and political backdrop. Growing public sentiment across the nation advocating for policies to narrow wealth disparities and increase taxation on the rich has fueled renewed interest in such fiscal measures. However, state tax policies are diverging, with some states prioritizing tax relief while others pursue new taxes on high-income individuals.

Analysts and market observers suggest that the outcomes of these November 2026 votes will serve as a crucial test for the "tax the rich" movement in progressive states. Even some Democratic leaders, like California Governor Gavin Newsom, have expressed opposition to the wealth tax, citing concerns about its potential to harm the state's competitiveness and fail to meet revenue expectations. In Washington, the governor's office argues that repealing the income tax would result in cuts to essential funding for education and childcare. These referendums will demonstrate how effectively states can balance budgetary needs with potential reactions from investors and high-net-worth individuals. Experts warn that even "one-time" taxes could have lasting impacts on future tax policies and complicate states' fiscal stability.
