California billionaire wealth tax prompts corporate moves and home sales as Page, Ellison reshape ties to state
California’s proposed 2026 Billionaire Tax Act would impose a one‑time 5% levy on residents with at least $1 billion of worldwide net worth measured Dec. 31, 2026, with payment due in 2027 and payable over five years.
- One‑time 5% levy: applies to worldwide net worth over $1 billion for California residents on Jan. 1, 2026; see the Official initiative text.
- Payment mechanics: tax due in 2027, may be paid over five years with a nondeductible 7.5% annual charge on unpaid balances; read the Berkeley analysis.
- Residency matters: domicile on Jan. 1, 2026, is the key trigger; moving entities or homes may not fully remove assets from the base (Baker Botts analysis).
- High‑profile responses: reports note shifts by Larry Page and a San Francisco home sale by Larry Ellison amid the debate (Fox Business report).
Overview: what the measure would do
The 2026 Billionaire Tax Act is framed as a constitutional amendment proposing a one‑time 5% tax on worldwide net worth for individuals who are California residents on Jan. 1, 2026, with the tax base measured on Dec. 31, 2026. Proponents, led by SEIU‑UHW, say revenue would support Medi‑Cal, K‑14 education and food assistance.
What counts toward the tax
The base includes businesses, securities, art and other intangible property. Some items—such as directly held California real estate—are treated specially or excluded, while real estate held through business entities can be included in an entity’s value. Valuation of illiquid assets is a major source of uncertainty; see the Berkeley economists report for detail.
How the tax would be paid and apportioned
If the measure is approved, the levy would be due in 2027 and may be paid over five years. Unpaid balances would incur an extra nondeductible 7.5% annual charge. The initiative includes an alternative apportionment method for people with multistate ties, but it generally cannot allocate less than 25% of the base to California in most cases (Baker Botts analysis).
“Because the base is global wealth, simply moving a corporate entity’s legal home does not automatically remove assets from the tax base.”
Why billionaires’ moves matter
News coverage has highlighted changes among the state’s wealthiest individuals and firms as the proposal gained attention. Reported actions include corporate re‑domiciling, property sales and shifts of personal residence — steps often taken to build a factual record of non‑residency or to change taxable apportionment.
Reported moves by Larry Page, Larry Ellison and others
- Larry Page: media reports say Page has moved certain companies or corporate entities to Delaware and Florida. Delaware is a common corporate domicile; Florida has no state income tax. These reports were framed by outlets covering the proposed tax but Page has not publicly tied the moves to the initiative (Fox Business report).
- Larry Ellison: reports note Ellison sold a San Francisco home for about $45 million. While directly held homes are generally excluded from the proposed tax base, property sales can affect residency claims and public perception (reporting).
- Other billionaires: some have re‑domiciled to Texas, Florida or Nevada in recent years for long‑standing tax and business reasons; those moves are now discussed as potential responses to the proposal (CBS explainer).
Legal and economic debate
Because the initiative takes the form of a constitutional amendment, legal challenges are widely anticipated if it reaches the ballot and voters approve it. Potential claims include arguments that the measure is a forbidden bill of attainder or that taxing worldwide wealth of certain individuals violates constitutional protections. See the Baker Botts analysis for legal considerations.
Revenue estimates vary: economists supportive of the plan project large sums—one study by Emmanuel Saez and colleagues estimates roughly $100 billion over five years under certain assumptions—while the Legislative Analyst’s Office characterizes revenue as “tens of billions” and highlights substantial uncertainty (Berkeley study).
Strategic logic behind leasing, selling and re‑domiciling
From a planning perspective, moves such as incorporating in Delaware, re‑domiciling entities, selling property or establishing primary residence in a zero‑income‑tax state can help support a legal claim of non‑residency before Jan. 1, 2026. However, because the initiative measures worldwide net worth and includes apportionment limits, such steps are not guaranteed to avoid the levy; they can, though, help build the factual record of non‑residency (Baker Botts analysis).
Implications for San Diego
Economic impact: San Diego’s economy — driven by defense, tourism, biotech and tech startups — could see changes in high‑end real estate demand, local philanthropy and certain investment activity if wealthy residents or firms leave. Yet the tax targets a small number of people (roughly 200–255 statewide), so short‑run direct job effects are likely limited (revenue study).
Political and social effects: locally, the measure could sharpen debates over funding for health services, schools and housing. If the tax passes and funds materialize for Medi‑Cal, K–14 education and food programs, San Diego could see more stable support for safety‑net services; conversely, reduced philanthropic giving or relocation of wealthy donors could create shortfalls for community groups (CBS explainer).

Note: the measure has not yet qualified for the November 2026 ballot and needs roughly 875,000 valid signatures to appear; signature and legal challenges will shape whether the measure reaches voters and how courts interpret its provisions (explainer).
