California’s proposed 2026 “Billionaire Tax Act” has become a case study in how wealth taxes can trigger relocation, legal planning, political countermeasures, and interest in second citizenship or alternative tax jurisdictions.
The proposal was backed by SEIU United Healthcare Workers West, which delivered more than 1.5 million voter signatures on April 27 to qualify the measure for the November 2026 ballot. That total was described as almost double the required number, giving the campaign a buffer against duplicate or ineligible signatures.
If approved, the measure would apply a one-time wealth tax to California residents based on their net worth as of January 1, 2026.
The proposed structure is:
- California residents with net worth above $1.5 billion would owe 5% of that wealth one time.
- A smaller rate would apply to those between $1 billion and $1.1 billion.
- Relocation after January 1, 2026 would not erase the obligation.
- The tax would be payable in installments over five years.
- A resident worth $20 billion on the assessment date would owe $1 billion.
- SEIU projects $100 billion in revenue over the full window.
- The money is earmarked for hospital preservation, public education, and food assistance.
The most important detail is the assessment date. The proposal is designed to reach backward to January 1, 2026, meaning people who were California residents on that date could still face liability even if they later leave the state.
Wealth relocation before the cutoff
California was described as having roughly 214 billionaires. Six reportedly left before the January 1 cutoff, including Google co-founders Larry Page and Sergey Brin, and former Uber CEO Travis Kalanick.
By SEIU’s own calculation, those departures removed $26.8 billion in taxable wealth from the proposal’s base. That was described as more than a quarter of the projected take.
The transcript also cites a February estimate from tech investor Chamath Palihapitiya that $700 billion had already moved out of California since the initiative was first announced. Forbes was cited as tracing a quiet buying spree on the Nevada side of Lake Tahoe to billionaire tax planning.
The broader point is that large taxpayers may move before formal tax changes take effect, especially when the law includes a clear assessment date.
Opposition campaign and countermeasures
Sergey Brin and former Google CEO Eric Schmidt co-founded Building a Better California to oppose the measure. The group reportedly raised more than $80 million in the first quarter and is advancing three counter-ballot initiatives.
The three countermeasures are described as follows:
- A constitutional amendment banning retroactive taxation, which would directly attack the wealth tax’s enforcement mechanism.
- A measure targeting education spending allocation rules that any new tax would need to follow.
- A measure adding audits and spending restrictions to revenue from any new levy.
Other contributors mentioned include Palantir co-founder Peter Thiel, Ripple chairman Chris Larsen, and Stripe CEO Patrick Collison. Total spending by ultra-wealthy donors on California’s 2026 election cycle was cited at more than $270 million, according to Fortune.
Governor Gavin Newsom was also described as opposing the measure, warning that driving out top earners could damage the state budget. The transcript says the top 1% of California filers supply nearly half of the state’s personal income tax revenue.
Why this matters beyond California
The California proposal is framed as part of a wider risk for high-net-worth Americans. The concern is that a successful state-level wealth tax campaign could encourage federal progressive Democratic politicians to push similar wealth tax proposals nationally.
According to the transcript, high-net-worth individuals starting at around $50 million in net worth are already taking steps such as:
- engaging lobbyists
- reorganizing finances
- reviewing ways to leave the U.S. tax system
- preparing for possible political changes in 2026 and 2028
The political timeline highlighted is a roughly 30-month window, based on the possibility of Democrats taking both houses of Congress in 2026 and the White House in 2028.
The people moving fastest are described not only as headline billionaires, but also founders, early-stage executives, and family office principals.
Three strategies being used
The transcript identifies three strategies being used at the same time by high-net-worth individuals.
First is political action. This includes locating and funding lobbyists or campaigns to oppose wealth tax legislation. The $80 million California counteroffensive is presented as the clearest example.
Second is structural tax planning. Tools mentioned include:
- the gift and estate tax exemption
- grantor retained annuity trusts, or GRATs
- Puerto Rico’s Act 60
The stated goal is to use currently legal structures before rules are tightened, capped, phased out, or scrutinized more heavily.
Third is investment migration. This means acquiring a second citizenship or residency as part of broader planning around exit tax, inheritance tax, and long-term exposure to the U.S. tax system.
Programs and regions drawing interest from Americans include:
- Caribbean citizenship-by-investment programs
- Turkish citizenship-by-investment
- African citizenship-by-investment programs
- European golden visa residency pathways
- Gulf state alternatives with territorial tax systems
The transcript does not specify which individual programs are most suitable or provide eligibility details.
Migration risk and legal uncertainty
The transcript cites research from Sweden and Denmark finding that each percentage-point increase in wealth taxation correlated with a 2% outward migration among wealthy taxpayers. California’s proposed rate is described as five times that threshold.
Legal challenges are expected if the measure passes. The main issue identified is the retroactive provision, which some legal scholars argue could violate state due process protections.
However, the transcript states that a simple majority of voters in November 2026 would be enough for the initiative to become law.
Practical implications
The California proposal shows how tax planning, relocation, and investment migration can become linked when a tax measure includes a clear cutoff date and retroactive features.
For people exposed to wealth, exit, estate, or inheritance tax risk, the key planning questions are:
- Where is tax residency established on the assessment date?
- Which assets are exposed under current law?
- Which structures are available before rule changes?
- Is relocation alone enough, or is broader restructuring needed?
- Would a second citizenship or alternative residency create useful flexibility?
- Are territorial tax jurisdictions relevant?
- What legal challenges could affect enforcement?
The main caveat is that the proposal has not yet become law. It still faces a ballot vote and likely constitutional litigation if approved. But the transcript argues that planning is already happening before the vote, because waiting until after a measure passes may leave fewer options.
