News Summary

California is advancing a proposal for a one-time, 5% tax on residents with net worths surpassing $1 billion, aiming to fill a projected $30 billion annual healthcare funding shortfall. The 2026 Billionaire Tax Act requires nearly 875,000 signatures to qualify for the November 2026 ballot and proposes allocating 90% of the tax revenue to healthcare and 10% to K-12 education. This initiative is seen as a response to growing economic inequality and seeks to impose taxes on the wealthy without burdening middle-class residents.

California is moving forward with a new proposal aiming to impose a one-time, 5% tax on residents with a net worth exceeding $1 billion. This proposed initiative, known as the “2026 Billionaire Tax Act,” has been submitted to the California Attorney General’s office. The objective of the tax is to address an anticipated $30 billion annual health care funding shortfall in the state.

If approved, the initiative could potentially appear on the November 2026 ballot. To qualify, it will require nearly 875,000 signatures from voters. The proposal is structured as an emergency measure to prevent severe cuts to health care funding that would result from projected federal funding shortfalls.

Under the proposed measure, roughly 90% of the revenue generated from the tax would be allocated to health care, while the remaining 10% would benefit K-12 public education. The total revenue from the tax is capped at $25 billion per year and would be deposited into a separate “Billionaire Tax Reserve Account.”

The proposal argues that the wealth of billionaires has “largely escaped fair taxation,” contributing to rising economic inequality in California. For compliance, all residential billionaires would have to declare their total net worth, taking into account assets such as private companies, real estate, and art. Tax payments can be settled either in full or over five years with interest, and those who underreport their wealth would face steep penalties.

Estimates suggest that about 180 billionaires currently reside in California, collectively holding approximately $2 trillion in wealth. Economists from UC Berkeley contributed to drafting the bill, which is backed by the Service Employees International Union (SEIU).

While proponents hail the tax as a modest and fair response to significant asset growth among billionaires, opponents voice concerns that it might drive these wealthy individuals to relocate to states with lower taxes. Critics believe this could adversely impact investment in California, potentially harming the state’s entrepreneurial ecosystem and capital investment landscape.

The initiative aims to bolster state revenue without imposing higher taxes on working and middle-class residents. Notably, the tax targets unrealized gains and asset valuations, which may present compliance challenges for financial advisors managing affected individuals.

The Attorney General’s office is expected to produce a title and summary of the initiative in the coming weeks. Should the proposal succeed, California could become the first state in the U.S. to implement a direct wealth tax on billionaires. This proposal is in line with a broader trend that seeks to address extreme wealth through taxation at both state and potentially federal levels.

Additional data reveals that non-billionaire Californians pay an average of 6% more of their economic income in taxes compared to the wealthiest residents. As discussions around wealth taxation continue, the proposed billionaire tax serves as a significant turning point in the ongoing debate about fiscal responsibility and equity in taxation.
