The 2026 Wealth Tax Wave: Why More High Earners Are Moving to Florida Than Ever

Something unusual is happening in state tax policy in 2026, and it has direct implications for where you choose to live.

Across the country, multiple high-tax states are simultaneously passing or advancing aggressive new levies on high-income and high-wealth individuals. Washington State — which had no income tax at all for 93 years — signed a 9.9% millionaire surtax into law in March 2026. California is pushing a wealth tax on billionaires while maintaining the highest marginal income tax rate in the country. New York is proposing additional surcharges while simultaneously expanding its already-aggressive residency audit program. Connecticut and New Jersey are both advancing millionaire surtax proposals. Illinois is facing pressure to abandon its constitutional flat tax requirement and add graduated rates targeting high earners.

This is not business as usual. This is a convergence — multiple major states moving in the same direction at the same time, in ways that compound each other’s effects on high-net-worth individuals with ties to more than one state.

The result is the largest acceleration of high-income migration to Florida in modern history. And the people who understand what is happening are moving now, before the window narrows further.

Washington’s Bombshell: The End of 93 Years Without an Income Tax

For nearly a century, Washington State’s identity as a no-income-tax state was one of its defining competitive advantages. That ended in March 2026.

The newly enacted Washington Capital Gains and High-Earner Surtax imposes a 9.9% rate on income above $1 million. Combined with the existing 7% capital gains excise tax on gains above $262,000 — which the state Supreme Court upheld in 2023 after years of legal challenges — Washington has fundamentally transformed its tax profile for wealthy residents in the span of a few years.

For a tech founder in Seattle with $3 million in income, the shift is jarring. Two years ago, that income was largely untaxed at the state level. Today, the effective marginal state tax burden on income above $1 million has jumped to the high single digits, with the expectation among tax professionals that rates will continue upward once the political and structural barriers have been broken.

Howard Schultz’s relocation from Seattle to Miami is now looking less like the idiosyncratic decision of one wealthy executive and more like the leading indicator it was. Washington’s transformation from a no-tax state into an aggressive taxer of high earners is precisely the kind of structural change that triggers mass migration — not because individuals are being cavalier about their civic obligations, but because the financial stakes are now simply too large to ignore.

California: Perpetual Escalation

California’s story is not new in 2026, but it keeps getting more extreme.

The state already imposes the highest marginal income tax rate in the country at 13.3%, reaching that rate at $1 million in income. The proposed California Wealth Tax — which has been introduced in various forms over recent legislative sessions — would impose a 1% to 1.5% annual levy on net worth above $50 million, a tax that applies to the stock of wealth rather than the flow of income. If enacted, it would follow California residents who leave for up to 10 years under the proposed “exit tax” provisions, attempting to tax unrealized appreciation on assets even after departure.

That exit tax provision is not law yet. But the direction of travel is clear, and sophisticated advisors are counseling clients not to wait for certainty. The window between “this is proposed” and “this is enacted” is narrow, and the consequences of being on the wrong side of the effective date can be severe.

California’s Franchise Tax Board has simultaneously been expanding its residency audit program. As more high earners attempt to relocate, California has increased its enforcement budget and its auditor headcount. The state is increasingly sophisticated about identifying nominally departed residents who maintain California ties — and the financial incentive to pursue them is larger with each passing year.

Ken Griffin’s move from Chicago to Miami received enormous coverage. Less discussed is the pattern it represented: Griffin was not alone, not exceptional, and not early. He was part of a wave of institutional investors, fund managers, and business owners who had been making the same calculus for years and who reached the same conclusion.

New York: The Audit State Gets More Aggressive

New York has the most developed residency audit infrastructure in the country, and it is getting bigger.

The Nonresident Audit Bureau — the dedicated unit within the Department of Taxation and Finance that does nothing but pursue high earners who claim to have left New York — has been growing. As departures accelerate, New York’s financial incentive to investigate those departures grows in parallel. The state has made public statements about expanding enforcement capacity, and tax practitioners who deal with the bureau regularly report increased activity over the past two years.

New York’s top marginal rate sits at 10.9% on income above $25 million, with the 9.65% rate kicking in at $2.155 million. New York City residents add another 3.876% on top of that. For a Manhattan resident earning $2 million annually, the combined city and state tax burden approaches $290,000 per year. Moving to Florida eliminates that entirely.

In Albany, proposals are circulating to impose additional surcharges on income above $5 million, to increase the estate tax, and to expand the reach of the statutory resident rule — the provision that allows New York to tax people as full residents even if their domicile is elsewhere, simply because they maintain a New York home and spend more than 183 days there. Proposals to lower that threshold, or to reduce the number of days that count toward the statutory resident test based on location of employment, have been floated in recent sessions.

Carl Icahn’s move from New York to Miami was followed by a widely reported audit dispute with New York over whether the relocation was complete enough. The case was eventually resolved, but it illustrated two things: first, that New York will pursue high-profile departures regardless of how complete they appear on the surface, and second, that the disputes are winnable — with documentation.

The lesson is not that New York is impossible to leave. The lesson is that leaving properly requires treating it as a serious, documented process, not an informal change of address.

The Multi-State Squeeze: NJ, CT, and Illinois

The wealth tax pressure in 2026 is not just a story about two or three states. It is a coordinated cultural and political moment across the high-tax belt.

New Jersey has proposed a millionaire surtax that would add 3% to 4% on income above $1 million, on top of its existing top rate of 10.75%. New Jersey already lost a significant portion of its high-income tax base when David Tepper relocated his hedge fund to Florida in 2015 — a move that reportedly cost New Jersey hundreds of millions in annual tax revenue — but the political response has been to propose higher rates rather than reconsider the approach.

Connecticut — which has watched substantial wealth migration toward Florida from Fairfield County for years — is in a similar position. The state’s top rate of 6.99% is comparatively moderate, but proposals to add graduated surcharges on income above $1 million and $5 million are advancing. Connecticut’s proximity to New York, the presence of major financial firms in Greenwich and Westport, and the historically transient nature of the hedge fund community make it more exposed to migration than many states.

Illinois presents a different but related dynamic. The state constitution currently requires a flat income tax, which has historically constrained Springfield’s ability to specifically target high earners. But proposals to amend the constitution and allow graduated rates — a measure that failed at referendum in 2020 but is expected to return — remain a persistent threat. Ken Griffin cited this explicitly when explaining his decision to move Citadel from Chicago to Miami. The flat tax was a protection. Its potential removal was a risk he chose not to accept.

Florida’s Structural Advantages Are Real and Durable

Florida is not just the default option by virtue of being warm. It has structural advantages that go well beyond climate, and some of those advantages are constitutionally protected in ways that make them more durable than a legislative promise.

No income tax, constitutionally protected. Florida’s prohibition on a state income tax is embedded in the state constitution. A simple legislative majority cannot impose one. Any future income tax would require a constitutional amendment, which requires a 60% supermajority in both chambers and then approval by 60% of Florida voters. This is a materially different level of protection than states where the income tax is a statutory creation that can be modified in a single legislative session.

No estate tax. Florida repealed its estate tax in 2004 and has shown no appetite for reinstating one. States like New York, with a top estate tax rate of 16% on estates above the exemption, impose significant intergenerational wealth transfer costs that Florida simply does not.

Homestead protection. Florida’s homestead exemption is among the most generous in the country. The homestead assessment cap limits annual increases in assessed value to 3% per year for primary residences, providing long-term property tax stability in a state where real estate values have risen substantially. The homestead also provides significant creditor protection under Florida law — a consideration for business owners and executives who carry personal liability exposure.

HJR 203 and potential property tax elimination. A proposed constitutional amendment working its way through the Florida legislature would, if passed and approved by voters, eliminate property taxes on primary residences entirely. This is not law, and it may not become law, but the political direction it represents — Florida actively competing for high-net-worth residents by reducing their tax burden further — is itself meaningful.

Florida vs. The Other No-Tax States

Florida is not the only state without an income tax. Texas, Nevada, Tennessee, Wyoming, and New Hampshire all offer various income tax exemptions. Why does Florida dominate the high-net-worth migration discussion?

Texas is Florida’s closest competitor for financial and business migration. Austin has attracted significant tech investment, and Houston and Dallas have deep business communities. But Texas has high property taxes — among the highest in the nation — that partially offset the income tax advantage. The climate is less universally appealing than Florida’s for the snowbird demographic (Houston and Dallas summers are hot, and the state offers less coastal lifestyle). Texas is a genuine alternative for certain profiles, particularly those with business operations in the central time zone.

Nevada attracts Las Vegas-adjacent financial figures, and Reno has become a relocation destination for California businesses seeking proximity to the Bay Area. But Nevada lacks the cultural and financial infrastructure for most East Coast money. The community of advisors, institutions, and professional networks that a high-net-worth individual needs doesn’t exist there at the same scale.

Wyoming is the preferred domicile for dynastic wealth structures — trusts, foundations, family offices — because of its unusually favorable trust laws. But it is not a realistic primary residence for most individuals, particularly those who want proximity to major airports, medical facilities, and financial centers.

Tennessee has no income tax on wages, but Nashville lacks the financial center infrastructure of Miami, and the state is still building the professional ecosystem that high-net-worth families require.

Florida wins for most high-net-worth individuals because it combines no income tax with established financial infrastructure, world-class medical facilities, major international airports, a large and sophisticated community of wealth advisors and tax specialists, and the lifestyle amenities that actually make a move feel like an upgrade rather than a sacrifice. Miami is now legitimately a global financial capital. Palm Beach has been the destination of choice for East Coast wealth for decades. Naples and Sarasota have mature professional communities. The state has everything you need, and it lacks the income tax.

The Data: Migration at Historic Scale

The numbers tell the story clearly. The U.S. Census Bureau reported net domestic migration to Florida of more than 674,000 people from 2020 to 2023 — the largest net inflow of any state in that period. Florida added roughly 1,000 net new residents per day during peak years of the post-pandemic migration surge.

This is not primarily retirees and service workers. Florida’s income tax advantage means it attracts, disproportionately, individuals at the high end of the income spectrum. The IRS Statistics of Income data — which tracks the income associated with migration, not just the headcount — shows Florida receiving outsized income inflows from New York, New Jersey, California, Connecticut, and Illinois. The income migrating to Florida exceeds the income migrating away by a substantial margin.

Miami’s transformation is the most visible manifestation of what this migration looks like in concentrated form. A decade ago, Miami’s financial sector was modest by global standards. Today it hosts offices and leadership teams from Citadel, Blackstone, Apollo, Icahn Enterprises, and dozens of hedge funds, private equity firms, and family offices that have relocated wholly or partially from New York. Brickell has become a genuine financial district. The professional infrastructure — tax attorneys, estate planners, prime brokers, private banks — that followed the money is now self-sustaining.

The migration has created a positive feedback loop. Each high-profile move makes the next one easier, because the professional and social infrastructure that the next mover will need is already there.

The Enforcement Paradox: More Departures Mean More Audits

Here is the dynamic that surprises most people: as more high earners leave, the remaining high-tax states don’t give up. They invest more in enforcement.

The math explains it. New York loses $130,000 to $150,000 in annual revenue when a $1 million earner successfully establishes Florida domicile. A team of specialized auditors who can recover that tax for even a fraction of departed residents is highly profitable for the state. As the base of potential audit targets expands — more people leave, more people are subject to review — the return on enforcement investment grows.

This is why the Nonresident Audit Bureau is growing, not shrinking, even as high earners leave. California’s FTB is hiring. New Jersey and Connecticut are expanding their residency audit programs specifically because there are more departures to contest.

The practical implication is important: the act of leaving is not the end of your exposure to your former state. New York can audit you for tax years going back three years under the standard statute of limitations, six years for substantial underreporting, and indefinitely in fraud cases. California has similar reach. The audit for your 2025 tax year could arrive in 2028, long after you assumed you were done with the state.

This is also why people who moved years ago — before the current audit environment became this aggressive — are increasingly receiving notices for past years. States are working through their backlog of departed high earners with renewed resources and motivation.

High-Profile Moves: The Pattern

The names are well-known by now. What is worth examining is the pattern they collectively represent.

Ken Griffin moved Citadel and Point72 from Chicago to Miami in 2022, explicitly citing Illinois’s pending constitutional amendment to allow graduated income taxes. The move transferred an estimated $250 million or more in annual Illinois tax revenue to Florida.

Carl Icahn relocated from New York to Miami, a move that generated a lengthy audit dispute with New York — and that he ultimately navigated. His case is a useful data point: New York pursued him, he had professional representation and documentation, and the matter was resolved. The audit is not the end of the story. It is a process you can survive with the right preparation.

Howard Schultz had established Florida residency well before Washington’s income tax became law, but his move looks prescient in retrospect. Seattle’s transformation from a no-tax city to a high-tax city happened faster than almost anyone predicted.

Beyond the household names, the hedge fund and private equity migration from Manhattan to Palm Beach and Miami represents thousands of individual decisions by managing directors, general partners, and portfolio managers — people whose names don’t appear in the press but whose moves collectively account for billions in migrated income. The pattern is consistent: high income, careful planning, thorough documentation, and a calculated judgment that the financial math justifies the disruption of relocation.

Why the Window May Be Narrowing

The case for acting sooner rather than later is not just about the money you save each year you are in Florida instead of a high-tax state. It is about two trends that are moving simultaneously.

States are getting more aggressive. The enforcement infrastructure being built in New York, California, New Jersey, and Connecticut is designed to contest departures for years to come. Audits are expanding. Subpoena tools are more sophisticated. Data sharing between states is more routine. The cost and complexity of a contested departure is rising.

Florida’s structural advantages may attract political competition. Florida’s no-income-tax constitution is durable, but not immovable. The state’s population growth and diversification mean its political landscape is different from what it was 20 years ago. Nothing suggests the income tax protection is under near-term threat — but the same could have been said about Washington State’s no-income-tax identity three years ago. The states that are most resistant to change are the ones with constitutional protections, which Florida has. But prudent planning doesn’t assume those protections hold forever.

The people moving in 2026 are moving before the enforcement environment gets worse, before the potential for future change materializes, and before the professional advisors and social infrastructure in Florida — already well-developed — becomes even more saturated with the newly arrived.

The people who wait for certainty, in state tax planning as in most things, end up paying the cost of having waited.

Why Documentation Has Never Mattered More

Given all of the above — more departures, more enforcement, more sophisticated audit tools — the quality of your residency documentation is more important in 2026 than it has ever been.

High-tax states are not going to take your word for where you lived. They are going to build an independent record of your movements from cell phone data, toll records, credit card transactions, airline records, and the dozens of other data sources now available to auditors with subpoena power. Your defense will need to be a contemporaneous record that either matches or exceeds the picture they have assembled.

The standard for a clean defense is a GPS-verified, day-by-day record of where you were — created in real time, not reconstructed from memory years later. That record is what tells an auditor that this is not a case worth pursuing. It is what makes your attorney’s job manageable if the case is pursued anyway. And it is what separates the people who win residency audits from the people who lose them.

Building that record requires starting now. You cannot go back and create location history for 2024 or 2025. The years when you had no tracking are years when you have no contemporaneous record — and no way to get one.

A Note on Professional Guidance

This post is a big-picture view of a fast-moving policy environment. It is not legal or tax advice.

Establishing Florida domicile, managing exposure to prior-state residency claims, and building a defensible record all involve complex, fact-specific legal and tax analysis that depends entirely on your individual circumstances. The rates, proposals, and political developments described above are changing rapidly. Some of the legislative proposals mentioned may not become law. Others may pass in forms different from what was proposed.

Work with a CPA and tax attorney who specialize in interstate domicile. There are firms that focus specifically on New York, California, and multi-state residency issues. The cost of that advice, paid upfront, is a fraction of what a contested audit costs at the back end — and given the enforcement environment described here, the risk of not getting it right is higher than it has been in a generation.

How Southbound Helps

The single most practical thing you can do in this environment is build a GPS-verified, day-by-day record of your time in Florida — starting now. Not when you think an audit might be coming. Not after you’ve been in Florida for a year. Now, from the day you establish residency, so that every year going forward has a clean, continuous record.

Southbound does this passively. The app runs in the background on your iPhone using iOS’s significant-location-change system, logging whether each day is spent in Florida or outside it. No check-ins, no journal entries, no discipline required beyond installing the app. The core metric is the Departure Budget — one number that tells you exactly how many days you can still spend outside Florida and remain on track for 183+. If you’re also tracking against a New York statutory resident threshold, you have that visibility in real time too.

Your location history lives entirely in your own iCloud account. Southbound never holds your data on its servers — your movements are private, yours alone, and accessible to no one but you. When an audit notice arrives for your 2026 tax year — potentially in 2028 or 2029, years from now — you will have a clean, exportable GPS-verified record of every day you spent in Florida. That is the kind of contemporaneous documentation that makes auditors reassess whether a case is worth pursuing, and the kind of defense that holds up if they pursue it anyway.
