Could Proposition 40 Accelerate UHNW Migration to Florida?
The Question Isn’t Just About Taxes Anymore
As a real estate professional working in Southwest Florida’s luxury coastal market, I have watched relocation decisions become increasingly sophisticated.
For high-net-worth individuals, entrepreneurs, investors and families with significant assets, the question is rarely simply:
“Where can I pay less in taxes?”
It is increasingly:
“Where do I want my family, lifestyle, business interests and real estate positioned for the next decade?”
California’s Proposition 40 has added another important variable to that conversation.
⸻
What Is California Proposition 40?
First, let’s separate fact from speculation.
Proposition 40 is officially scheduled for the November 3, 2026 California General Election. According to California’s nonpartisan Legislative Analyst’s Office (“LAO”), the measure would impose a one-time state tax equal to 5% of the net worth of individuals who were California residents on January 1, 2026 and meet the billionaire threshold.
The official California Secretary of State summary describes the measure as applying to certain individuals and trusts with covered assets valued above $1 billion. Covered assets apparently include businesses, securities, art, collectibles and intellectual property held as of December 31, 2026, while some real property and certain pensions and retirement accounts are excluded.
The proposed tax would be due in 2027, with taxpayers permitted to spread payments over five years under specified terms. The LAO estimates that the state could collect tens of billions of dollars over several years, although the exact amount is difficult to predict.
This is not simply another discussion about California’s income-tax rates.
It is a one-time tax based on wealth, including unrealized gains.
⸻
Does Proposition 40 Mean Billionaires Will Leave California?
This is where I believe we need to be careful.
We don’t know yet.
The California Legislative Analyst’s Office specifically notes that some billionaires could respond to the measure by leaving California, potentially reducing the state’s ongoing income-tax revenue. But the magnitude of that response is uncertain.
So I would not necessarily suggest that Proposition 40 will definitely cause a mass migration to Florida.
What I would say is this:
Major changes in tax policy can become part of a much larger conversation about long-term domicile, wealth planning and lifestyle.
And those conversations do invariably influence real estate decisions.

Why Florida Continues to Attract High-Net-Worth Buyers
Florida has one significant structural advantage that is easy to verify:
Florida does not impose a personal state income tax. The Florida Department of Revenue confirms that individuals do not have a Florida personal income-tax filing requirement.
But in my experience, sophisticated buyers rarely make a relocation decision based on one tax consideration alone.
They are evaluating an entire ecosystem.
For UHNW families, entrepreneurs and investors, that can include:
- Tax and regulatory environment
- Business climate
- Estate, wealth-planning and asset protection considerations
- Privacy and security
- Healthcare
- Education
- Private aviation infrastructure
- Recreation and wellness
- Quality of life
- Luxury real estate
- Long-term family objectives
That is why I believe Florida’s appeal is broader than taxation alone.

Florida Isn’t One Luxury Market
One of the most important things I explain to relocating buyers is that Florida’s luxury markets are not interchangeable.
Miami
Miami can be compelling for buyers who prioritize international connectivity, finance, entrepreneurship, private aviation and a highly cosmopolitan lifestyle.
Palm Beach
Palm Beach offers a very different environment, with an established luxury market, privacy, and legacy properties, yet with proximity to major financial and business centers.
Naples
For buyers seeking quiet luxury, privacy, wellness and a lower-density coastal lifestyle with a small town vibe, Naples offers a distinctly different proposition.
This is particularly relevant to successful entrepreneurs after a liquidity event, multi-generational families and individuals who have reached a stage where lifestyle quality is more important than business access.
⸻
Why I Believe Naples Deserves a Closer Look
The Naples, Florida market is especially interesting to me because luxury here is often less about visibility and more about privacy, space, security, wellness and lifestyle.
Within the broader Naples–Bonita Beach market, buyers can choose among very different environments—from waterfront estates and private communities to resort-style luxury condominiums featuring lock-and-leave convenience.
For example, communities such as Barefoot Beach, Port Royal, Bay Colony and Mediterra each offer a different interpretation of Southwest Florida luxury.
That is why I don’t believe the question should simply be:
“Should I move to Florida?”
The better question is:
“Which Florida community fits the way I want to live?”
⸻
What Should UHNW Buyers Do Before Relocating?
If California tax policy is prompting you to investigate Florida, I recommend taking a measured approach.
1. Start with domicile—not the house
Purchasing Florida real estate does not automatically establish Florida domicile.
Residency and domicile involve legal and factual considerations that should be evaluated with qualified tax and legal counsel.
2. Define your lifestyle first
Ask yourself:
- Do I want a primary residence or second home?
- How important is privacy?
- Do I want waterfront living?
- How often will I travel internationally?
- Do I need private aviation access?
- Is golf or wellness important?
- Do I want lock-and-leave convenience?
- In what type of environment do I want my children or grandchildren to grow up?
These answers can dramatically change which Florida market makes sense.
3. Evaluate the real estate strategically
For UHNW buyers, real estate can be both a lifestyle decision and a substantial capital allocation.
That makes location, community structure, insurance, taxes, carrying costs, liquidity and long-term appreciation important considerations.
4. Build the professional team early
A major relocation may involve:
- CPA
- Tax counsel
- Local estate-planning and real estate attorney
- Family Office advisor
- Insurance professional
- Real estate professional
- Business in-house counsel
The real estate strategy should complement the broader financial and estate strategy—not operate independently.

My Perspective
I don’t believe Proposition 40 should be viewed as a guaranteed catalyst for a mass exodus from California.
But I do believe it is another reason for UHNW families to take a fresh look at where they live, how they structure their affairs and what they want their next chapter to look like.
The IRS continues to publish interstate migration data based on address changes reported on individual income-tax returns, providing a factual framework for studying movement between states. The most recent published dataset covers 2022–2023.
That means we can measure migration—but we should be careful not to attribute every move to taxation.
People move for many reasons. Taxes can be one factor. Lifestyle can be another.
Family, business, weather, healthcare, privacy, security and real estate can all matter.
In the luxury market, I believe the most interesting relocation decisions happen where those factors intersect.

The Bottom Line
California Proposition 40 is now a real ballot measure—not simply a theoretical discussion. If approved, it would create a significant wealth tax for qualifying California billionaires.
But whether it ultimately changes migration patterns remains to be seen.
For Florida, the larger story is already broader than tax proposals in any one state.
Florida offers no personal state income tax, while markets such as Miami, Palm Beach and Naples provide very different lifestyle and investment environments.
For the right buyer, Naples in particular offers something increasingly valuable: the ability to live exceptionally well, without living in the limelight.
And perhaps that is the real story behind today’s UHNW relocation conversation.
It isn’t simply about where wealth is taxed. It’s about where wealth, family and lifestyle come together.
If you’re considering relocating to Naples, Bonita Springs, Barefoot Beach or another community along Florida’s Paradise Coast, I would welcome the opportunity to help you evaluate the market from a lifestyle and real estate perspective.
