California Gubernatorial Candidates Divided on Billionaire Tax Proposal
California’s gubernatorial race is heating up as candidates face a defining issue: the Billionaire Tax Act, a proposed 5% one-time tax on the net worth of billionaires living in the state. The measure, championed by progressive lawmakers like Rep. Ro Khanna, has become a litmus test for candidates navigating the state’s deep political divisions—and a potential liability for Democrats seeking to balance progressive ideals with donor relations.
Who’s Leading the Debate?
The proposal has split the Democratic establishment, with outgoing Gov. Gavin Newsom—a likely 2028 presidential contender—vehemently opposing the tax. In a recent interview with the Modern York Times, Newsom declared, “This will be defeated—there’s no question in my mind. I’ll do what I have to do to protect the state.” His stance reflects concerns from business leaders and high-net-worth individuals who could face the tax’s financial impact.
Ro Khanna: The Progressive Backer
Rep. Ro Khanna, a vocal advocate for the wealth tax, has framed it as part of a broader “new tech social contract” aimed at rebalancing wealth in an era of rapid technological change. Khanna, who has his sights set on a potential 2028 primary challenge against Newsom, argues the tax is necessary to fund critical public services like education and healthcare. His support has energized progressive activists but also drawn skepticism from moderates wary of alienating Silicon Valley donors.
Katie Porter and Eric Swalwell: The Cautious Center
While candidates like Katie Porter and Eric Swalwell have avoided taking hardline positions, their past records suggest they may lean toward support. Porter, a consumer advocate, has historically backed progressive tax policies, while Swalwell’s votes in Congress align with wealth redistribution efforts. Both, although, have been careful not to endorse the proposal outright, likely to avoid donor backlash.
Why This Issue Could Reshape the Race
The wealth tax debate isn’t just about policy—it’s a proxy battle for the soul of California’s Democratic Party. Supporters argue it’s a moral imperative to address inequality, while opponents warn it could drive wealthy residents and businesses to leave the state, exacerbating budget shortfalls. The outcome could also influence the national Democratic Party’s approach to wealth taxation ahead of the 2028 election.
Economic Concerns
Critics, including Newsom, argue the tax could trigger a mass exodus of billionaires, leading to lost revenue and job opportunities. A 2025 study by the Tax Foundation estimated that a similar proposal in New York led to a net loss of $1.2 billion in annual tax revenue within two years due to outmigration.
Donor Relations
Candidates like Swalwell and Porter face a delicate balancing act: progressive voters expect bold stances on inequality, but major donors—many of whom stand to pay the tax—could punish candidates who endorse it. This tension has led to a strategic silence from several contenders, who are waiting to see how the debate plays out before committing.
National Implications
California’s outcome could set a precedent for other states and the federal government. If the wealth tax passes, it may embolden similar measures nationwide. Conversely, its defeat could signal the limits of progressive taxation in America’s most populous state.
What’s Next for the Billionaire Tax Act?
The proposal’s fate hinges on three key factors:
- Legislative Momentum: The California State Legislature must pass the bill before it reaches Newsom’s desk. Current polling shows mixed support, with urban Democrats largely in favor and suburban/rural districts skeptical.
- Gubernatorial Succession: The next governor’s stance will be decisive. If a candidate like Khanna wins, the tax’s chances improve significantly. If a moderate like Swalwell or Porter takes office, the proposal may stall.
- Legal Challenges: Wealthy individuals and business groups are already preparing lawsuits, arguing the tax violates constitutional protections against uncompensated takings.
