The proposed 2026 California Billionaire Tax Act — a one-time 5% tax on net worth exceeding $1 billion for individuals who were California residents as of January 1, 2026 — has generated significant concern among high-net-worth families. Even if your net worth is below this threshold, the initiative may lead to heightened FTB residency audits and underscores the importance of proactive planning. For Ontario and Inland Empire families, integrated strategies around residency, trusts, gifting, and asset protection may be highly beneficial to evaluate under both the proposed wealth tax and broader California tax environment.
What Is the Proposed 2026 California Billionaire Tax?
The One-Time Wealth Tax for State-Funded Health Care, Education, and Food Assistance Programs Initiative (commonly called the Billionaire Tax Act) would impose a one-time 5% tax on worldwide net worth for California residents with $1 billion+ in assets as of December 31, 2026.
Key Details:
- Applies to individuals (married couples treated as one) who were California residents on January 1, 2026.
- Tax calculated on net worth (stocks, bonds, business interests, certain real estate held in entities, etc.).
- Payable in installments over five years with deferral charges.
- Projected to affect roughly the top 200 wealthiest Californians and raise substantial revenue if passed in November 2026.
While framed as a “one-time” tax on billionaires, some estate and tax planners believe it could increase scrutiny on all high-net-worth residents and those considering relocation.
How the Proposed Wealth Tax Increases Residency Risks
California’s Franchise Tax Board (FTB) is known for aggressive residency audits, especially for high-net-worth individuals moving to no-income-tax states. The wealth tax proposal may heighten this risk because:
- Residency status as of January 1, 2026, determines applicability.
- FTB uses a facts-and-circumstances test focusing on domicile, time spent in California, family ties, property, and more.
- Partial-year moves or incomplete severance of ties can trigger multi-year audits with back taxes, penalties, and interest.
Even families well below $1 billion could face increased regulatory scrutiny due to heightened awareness and enforcement focus.
Proactive Strategies to Manage Your Assets in 2026
1. Residency Planning
Consider documenting a clear intent to change domicile if relocating. This may include updating a driver’s license, voter registration, primary residence, and financial accounts, As well as minimizing California days and ties. Work with professionals to help build an audit-resistant record.
2. Estate and Gift Planning Under OBBBA
Leverage the higher federal estate/gift tax exemption (~$15 million per person in 2026) for gifting, SLATs, GRATs, or irrevocable trusts before any potential wealth tax valuation date.
3. Asset Protection and Structuring
- Review business entities and real estate holdings.
- Consider irrevocable trusts and family limited partnerships.
- Evaluate charitable strategies and Qualified Charitable Distributions.
4. Tax-Loss Harvesting and Income Management
Offset gains and manage MAGI to maintain flexibility.
5. Comprehensive Modeling
Run multi-year scenarios comparing stay-in-CA vs. strategic relocation, factoring in Prop 13 benefits, capital gains, and Medicare IRMAA.

California-Specific Considerations for Inland Empire Families
Many Ontario-area families hold significant real estate protected by Prop 13. Relocation or restructuring decisions must balance potential wealth tax exposure against property tax resets and lifestyle factors. Proximity to Nevada offers options, but clean execution is critical to support your position under FTB review.
