Can Billionaires Escape California's Billionaire Tax? The Russell Peters Precedent Suggests No

Wealthy residents are reportedly scrambling to relocate out of California before a critical deadline, hoping to dodge a landmark 5% one-time wealth tax proposal expected to reach voters in November 2026. But history—particularly the legal saga of comedian Russell Peters—suggests that leaving California isn’t as simple as packing up and claiming residency elsewhere.

The Tax That’s Making Billionaires Nervous

California’s proposed wealth tax represents one of the most aggressive attempts to raise revenue from the ultra-wealthy. The plan would impose a single 5% levy on net assets exceeding $1 billion, targeting over 200 of the state’s richest residents. Drafters estimate it would generate approximately $100 billion, funding California’s Medicaid gaps from 2027 through 2031. The scope is remarkably broad, covering publicly traded stocks, private company equity, personal assets exceeding $5 million, and retirement accounts over $10 million—with limited exemptions.

Governor Gavin Newsom and the broader business community have mounted fierce opposition, warning that such a tax could trigger an exodus of tech entrepreneurs and their enterprises, decimating the state’s long-term income tax base just as the artificial intelligence boom promises economic recovery. Proponents counter that billionaires currently bear a disproportionately light tax burden, exploiting loopholes that allow them to maintain lavish lifestyles through stock-pledge loans rather than triggering capital gains taxes.

The Cat-and-Mouse Game: Relocation Strategy vs. Tax Authority Determination

Tech billionaires have wasted no time testing the waters. Google co-founder Larry Page recently acquired two Miami properties for $173.5 million and relocated affiliated companies, positioning himself as a Florida resident before the crucial deadline. Other wealthy individuals are consulting with tax lawyers about similar moves.

Yet California’s tax authorities are not novices at this game. The state has a formidable history of aggressively contesting relocation claims, particularly when substantial wealth is at stake. The determination of tax residency, as San Francisco tax attorney Shail P. Shah explains, hinges on subjective factors that courts must weigh holistically: Where does the taxpayer maintain business and personal ties? How much time do they actually spend in California? Do they hold property there? What do financial records reveal about their actual lifestyle?

This is where the Russell Peters case becomes instructive.

The Russell Peters Precedent: When Relocation Claims Fail

In September 2025, the California Office of Tax Appeals issued a ruling that fundamentally shapes the relocation debate. The case involved Russell Peters, the Canadian-born comedian who attempted to sever California tax residency for years 2012-2014. On paper, Peters had done everything right: he owned a home and apartment in Nevada (a state without income tax), maintained three Nevada-registered companies, held a Nevada driver’s license, and filed California tax returns claiming non-resident status with a Canadian address.

None of it mattered.

California courts discovered that Peters still owned property in California, his daughter from a previous relationship lived in the state, and his credit card statements revealed he spent more days in California than anywhere else. Despite his careful restructuring, the court determined Peters was indeed a California resident throughout the disputed period—and owed back taxes plus penalties for all three years.

The Peters decision drew heavily from the 2021 Bracamonte precedent, where a couple attempting to relocate to Nevada to escape taxes on a business sale valued at over $17 million lost their case. That case established the broad standard now guiding courts: comprehensively evaluate all evidence, including state registrations, personal and professional affiliations, actual residence duration, and property holdings.

Why Tech Billionaires Face Particular Challenges

For Silicon Valley billionaires, the Peters ruling creates a formidable obstacle. Jon D. Feldhammer, head of the San Francisco office at Baker Botts LLP, has fielded consultations from multiple billionaires seriously contemplating relocation. Yet he acknowledges the practical difficulty: “If you’re a billionaire with a massive social network in California, regularly play golf at Pebble Beach, and grew up in Palo Alto, it’s extremely difficult to argue convincingly that you don’t intend to eventually return to California.”

The proposal’s drafters have anticipated relocation attempts by embedding specific anti-evasion measures. Tax residency is determined as of January 1, 2026, while the tax’s valuation date is December 31, 2026—creating a gap that some have exploited. However, the proposal explicitly prevents billionaires from circumventing taxes through relocation or asset undervaluation.

Enforcement Mechanisms: Making It Harder to Hide

The 2026 Billionaire Tax Act includes sophisticated asset valuation safeguards designed to prevent manipulation. For privately held companies, the default valuation uses “book value plus annual book profit multiplied by 7.5 times,” with a floor preventing valuations below recent financing rounds. Personal assets like artwork and jewelry cannot be valued below their insured amounts. Taxpayers dissatisfied with valuations can appeal with independent appraisals.

For those with predominantly illiquid assets, the proposal permits “selective tax deferral account” agreements, allowing billionaires to postpone payments until they sell equity or withdraw proceeds. However, those choosing installment payment over five years must pay interest.

Additionally, charitable donations are only deductible if formalized through binding agreements by October 15, 2025. Real estate purchased in 2026 cannot claim exemption if determined to be purchased for tax avoidance purposes.

Constitutional and Legal Minefields

The proposal faces serious legal challenges. Feldhammer’s team identified eight distinct avenues for constitutional attack—on both federal and state grounds. One centers on retroactivity: if voters approve the tax in November, it applies to anyone identified as a California resident on January 1, 2026. While the U.S. Supreme Court has permitted retroactive changes to federal income and estate taxes (such as provisions in the Trump Big and Beautiful Act passed in July 2025), the current Court’s position on state wealth taxes remains uncertain.

Feldhammer’s strategic advice to billionaires: relocate before the November vote to preserve defenses against retroactive application. “The earlier you move, the stronger your position,” he suggests—though the Russell Peters case casts doubt on whether such moves actually work.

The proposal’s academic drafters counter these concerns, arguing that states have historically wielded broad authority to tax residents’ property and wealth, provided due process protections apply. Three law professors and UC Berkeley economist Emmanuel Seth—director of the Stone Center for Wealth and Income Inequality—emphasize that only federal wealth taxes face constitutional prohibition, not state-level ones.

The Cost Calculus: Lost Revenue or Massive Gain?

Estimates diverge sharply on the proposal’s economic impact. Drafters anticipate $100 billion in revenue from over 200 billionaires, based on Forbes net worth valuations. However, California’s Legislative Analyst’s Office warns the state could lose hundreds of millions—potentially billions—in personal income tax revenue annually if billionaires successfully relocate their operations.

This concern carries weight given California’s existing tax structure. The state boasts a top individual income tax rate of 13.3%, including a 1% surtax on income exceeding $1 million (approved in 2004). Additional brackets for incomes above $250,000 (or $500,000 for married couples), approved in 2012 and extended through 2030, further escalate burdens.

Notably, nearly half of California’s personal income tax revenue originates from the wealthiest 2% of residents. Yet scholars argue billionaires currently contribute only about 2.5% of the state’s total personal income tax—far below their wealth share—because they structure income through mechanisms avoiding taxation (stock pledges for loans rather than sales).

The tax aims to correct this gap by directly taxing wealth regardless of whether it has been converted to taxable income. However, founders facing illiquidity dilemmas face a different problem: if forced to sell shares to pay wealth taxes, the proceeds trigger combined federal and California capital gains taxes of 37.1%, requiring even larger share sales to cover the tax liability itself—a cascading dilution of ownership stakes.

The National “Tax the Rich” Movement

California is not alone in aggressive wealth taxation. New York City maintains the nation’s highest combined state and city income tax rate. The state’s top individual rate stands at 10.9%, layered atop a 3.9% city-level rate. Newly elected Mayor Zohran Mamdani, who won office last November despite billionaire-funded opposition to his campaign, has promised to raise the city-level rate on incomes exceeding $1 million to 5.9%, bringing the combined rate to 16.8%.

The parallels are striking: both coastal wealth centers are simultaneously tightening the fiscal screws on billionaires, creating synchronized pressure for relocation—yet the Russell Peters precedent suggests tax authorities will pursue such relocations aggressively.

The Road Ahead: Hurdles Before Implementation

Before reaching voters, the proposal must clear significant procedural hurdles. The state must certify it and collect 875,000 valid voter signatures by the end of June 2026. Even if approved, fierce litigation from affected parties is inevitable. The proposal drafters have attempted to preempt legal challenges through strategic clause design and by offering constitutional amendments.

A PwC analysis notes that California voters have historically supported tax increases on the wealthy, though they also passed Proposition 13 in 1978, imposing strict property tax limitations—a contradiction that complicates predictions. Proposition 13’s 1% property tax cap, with annual assessed value increases capped at 2% unless property changes hands, has shaped California fiscal policy for decades. The current proposal notably exempts real estate held through revocable trusts to avoid Proposition 13 conflicts, though partnership-held real estate remains subject to the wealth tax.

The Lesson From Russell Peters: California Collects

What the Russell Peters case ultimately demonstrates is that California’s tax authorities possess formidable tools for enforcing residency determinations. Despite Peters’ careful Nevada restructuring, the state prevailed by examining the totality of circumstances—property ownership, time spent, family connections, financial patterns.

For billionaires contemplating relocation to escape the proposed wealth tax, this precedent offers an uncomfortable truth: leaving California requires more than purchasing out-of-state property and filing residency forms. Courts will examine whether you truly severed ties, whether your declared departure aligns with your actual behavior, whether your business interests and social networks actually detached from the state.

Google co-founder Larry Page’s Miami purchases may prove insufficient if challenged. The social and business networks of Silicon Valley billionaires—decades of connections, ongoing investments, family ties—create an evidentiary trail that Russell Peters ultimately could not overcome.

As California pushes forward with one of the nation’s most aggressive wealth tax proposals, the Russell Peters precedent whispers an uncomfortable warning to fleeing billionaires: the state tends to win these battles. Those hoping to escape the November 2026 tax through relocation may find, like Russell Peters did, that California’s tax authorities look deeper than residency claims suggest.
