Analysis of the New York to Florida migration, updated for August 2026. What the Mamdani election actually did and did not change, the current Census numbers (50,661 New York to Florida movers in 2024), the Citizens Budget Commission $9.2 billion income transfer through 2022, the county-by-county destination breakdown, and where the tax proposals landed in Albany.

Quick Summary

Zohran Mamdani's November 2025 election as New York City mayor became a talking point in the long-running New York to Florida migration story, but the tax proposal behind the headlines has not been enacted. A New York City personal income tax increase requires authorization from Albany, and the 2026 legislative session ended without the proposed 2-percentage-point surcharge on income above $1 million; the enacted FY2027 State Budget instead created a New York City pied-a-terre tax on non-primary residences effective July 1, 2026. New York City income tax rates therefore still top out at 3.876%, for a combined state and city top marginal rate of 14.776%. The underlying migration is real but smaller than the headlines: 50,661 people moved from New York to Florida in the 2024 American Community Survey (down from 71,138 in 2023), and the Citizens Budget Commission found a net 30,000 New York City residents moved to Miami-Dade and Palm Beach counties in the five years through 2022, taking about $9.2 billion of income with them. Establishing Florida domicile properly requires more than a Florida address: New York Tax Law §605 and 20 NYCRR §105.20 impose a 183-day statutory residency rule and a permanent place of abode test, and the 2025 Tax Appeals Tribunal decision in Matter of Hoff confirmed that paperwork alone cannot stand as a complete record without substantive ties.

Key Takeaways

1

The 2% millionaire surcharge was proposed, not enacted

A New York City income tax increase requires State authorization from Albany. The 2026 legislative session ended without the 2-percentage-point surcharge on income above $1 million, so the combined state and city top marginal rate remains 14.776%, not 16.8%. What the FY2027 Budget did enact is a New York City pied-a-terre tax on non-primary residences, effective for city fiscal years beginning July 1, 2026.

2

$9.2 billion in income moved from New York City to Miami-Dade and Palm Beach in the five years through 2022

The Citizens Budget Commission found a net 30,000 New York City residents relocated to those two counties: more than 26,000 to Miami-Dade with a per capita income of about $266,000, and almost 20,000 to Palm Beach with a per capita income of about $190,000.

3

Florida domicile is intent-based, not day-count-based

Florida Statutes §222.17 (Declaration of Domicile), §322.031 (driver license residency), and §97.041 (voter registration) form the documentation stack. There is no minimum day count, but New York will impose its own.

4

New York's 183-day statutory residency rule is the audit hammer

New York Tax Law §605 and 20 NYCRR §105.20 tax you as a resident if you spend more than 183 days in New York and maintain a permanent place of abode. This is the test most NY-to-FL movers fail.

5

Matter of Hoff (October 2025) confirmed paperwork is not enough

The NYS Tax Appeals Tribunal upheld a deficiency of approximately $60,000 against a couple with Florida driver licenses, voter registration, and a Declaration of Domicile because they kept a New York home and substantive New York ties. The Tribunal decided the case under the clear-and-convincing-evidence standard for changing domicile. Tribunal docket: DTA No. 850209.

6

There is no rate-increase deadline to beat, but the audit clock is real

Because the surcharge was not enacted, do not let a "move before the rates hit" pitch drive your timing. The durable reason to file a clean final part-year IT-203 with a stated departure date is that it starts the NYS DTF audit window running; failing to file means the window never starts.

7

Sell or rent the NYC pied-à-terre or pay the abode tax

The "permanent place of abode" prong is the most-litigated piece of New York residency law. Keeping a NYC apartment available for use, even if rarely occupied, can trigger statutory residency. Convert to a true rental with a property manager or sell.

8

Port St. Lucie is the overlooked middle-class NY exit corridor

moveBuddha 2025-2026 forecast shows a +1.67 in-to-out ratio with 72.4% YoY growth. Suffolk County (Long Island) middle-class homeowners cashing out $800K homes are buying $400K new construction in St. Lucie County.

Updated August 2026. This article originally described the New York to Florida migration as it looked in December 2025, in the weeks around Zohran Mamdani's election. The tax proposal that drove those headlines has since been through a full Albany session. This version keeps the 2025 record intact but dates it explicitly, and states where the policy actually stands now.

What Happened in Late 2025, and What Has Happened Since

In the run-up to the November 4, 2025 New York City mayoral election, South Florida developers reported a surge of New York buyers. Miami developer Isaac Toledano, CEO of BH Group, told Fox Business in a story published November 5, 2025 that his firm had signed more than $100 million in contracts with New York buyers in the preceding few months, roughly twice what New York buyers had signed with the firm in all of the prior year. Toledano attributed it to the election rather than to a post-election stampede: "I think the election accelerated how people make decisions," he said, adding that buyers were "nervous [for] what's coming, how it's going to affect their lifestyle."

That is the actual, sourced version of the story. It is a real datapoint about one developer's order book in the autumn of 2025, and it should be read as a single firm's experience rather than as a measurement of statewide migration.

The policy story has moved on. Mamdani campaigned on a 2-percentage-point city income tax surcharge on income above $1 million, which, stacked on top of New York's 10.9% top state rate and New York City's 3.876% top city rate, would have produced a combined top marginal rate of roughly 16.8%. But New York City cannot raise its own personal income tax: the increase requires authorization from the State Legislature in Albany, and Governor Hochul opposed it throughout the budget process. The 2026 legislative session ended without the surcharge. As of August 2026 it remains a proposal, not law, and the combined New York State and New York City top marginal rate is still 14.776%.

What Albany did enact in the FY2027 State Budget is a New York City pied-à-terre tax on non-primary residences, effective for New York City fiscal years beginning July 1, 2026, with an annual surcharge on qualifying second homes and a scheduled sunset of June 30, 2031 unless extended. For someone leaving New York City while keeping an apartment there, that is the change that actually bites.

The underlying migration, meanwhile, is real, long-running, and smaller than the headlines. Between 2018 and 2022 a net 30,000 New York City residents moved to Miami-Dade and Palm Beach counties, taking roughly $9.2 billion of income with them, according to the Citizens Budget Commission. In the most recent Census data, 50,661 people moved from New York to Florida during 2024. Those are the numbers to plan around.

The Numbers: A Structural Economic Shift

The New York-to-Florida migration is not new, and it is not a straight line up. Here is what the published data actually shows, with vintages stated so you can check it.

Migration Volume: The Scale of the Flow

  • 50,661 people moved from New York to Florida during 2024, and 28,080 moved from Florida to New York, a net loss of about 22,600 for New York (U.S. Census Bureau, 2024 American Community Survey 1-year estimates, released January 21, 2026; margin of error ±6,714)
  • 71,138 people made the same move during 2023, per the prior ACS vintage, so the 2024 number is a meaningful step down rather than an acceleration
  • In the 2024 data, New Jersey (56,799) edged past Florida as the single largest destination for people leaving New York. In 2023, Florida (71,138) was well ahead of New Jersey (55,926).
  • $9.2 billion of income moved with a net 30,000 New York City residents relocating to Miami-Dade and Palm Beach counties over the five years through 2022 (Citizens Budget Commission)
  • Q2 2025: New York counties (NYC, Nassau, Suffolk) were the #1 out-of-state origin for movers to Southeast Florida (Miami Association of Realtors)

To put this in perspective, the Florida Demographic Estimating Conference adopted a revised forecast on June 22, 2026 that puts Florida's April 1, 2026 population at 23,708,635 (up 1.41% year over year) and projects 24,018,133 for April 1, 2027. Over the five years from April 2026 to April 2030 the Conference expects an average of 297,200 net new residents per year, or 814 per day, a compound annual growth rate of 1.24%. The Conference lowered its April 2026 net domestic migration estimate at that meeting, and it notes that deaths have exceeded births in Florida every year since the 2020-21 fiscal year, so all of Florida's growth now comes from net migration.

The Wealth Transfer: Following the Money

The migration story becomes more significant when you track the income moving, not just the people. From the Citizens Budget Commission analysis of New York City taxpayer outmigration over the five years through 2022:

  • Miami-Dade: more than 26,000 people, per capita income of about $266,000
  • Palm Beach: almost 20,000 people, per capita income of about $190,000
  • Combined: a net 30,000 movers carrying about $9.2 billion of income
  • Context: the same analysis found that New York's share of the nation's millionaires fell from 12.7% in 2010 to 8.7% in 2022, even though the raw count of New York millionaires roughly doubled over that period
  • Young wealthy households (ages 26-35, $200k+ earners): a SmartAsset analysis of IRS migration data reports Florida gaining 1,786 per year while New York loses 345 per year

This isn't retirees cashing out pensions. This is prime earning years—entrepreneurs, financial professionals, tech executives, and business owners in the 26-44 age range who represent decades of future tax revenue. When they leave, they take not just current income but future wealth creation with them.

The Mamdani Effect: What Was Proposed, and Where It Landed

New York has always had high taxes. The 2025 election put a specific number on the table and gave people a reason to act on a calculation many had already run. Here is what was proposed, and what survived Albany.

The Policy: Proposed vs. Enacted

  • +2% city income tax surcharge on income above $1 million: PROPOSED, NOT ENACTED. New York City cannot raise its own personal income tax without State authorization. The 2026 Albany session ended without the surcharge; the Legislature backed versions of it, the Governor opposed it, and it did not make the enacted budget. It could return in a future session.
  • Combined NY state + city top marginal rate: still 14.776% (10.9% state above $25 million of taxable income, plus 3.876% city). The 16.8% figure describes what the top marginal rate would have been with the surcharge.
  • Pied-à-terre tax: ENACTED. The FY2027 State Budget authorized a New York City annual surcharge on residential property that is not the primary residence of the owner, an immediate family member, or an arm's-length tenant, effective for city fiscal years beginning July 1, 2026, with a sunset of June 30, 2031 unless extended. In the first phase it reaches one-to-three-family homes at $5 million or more of value and condominiums and co-ops at $1 million or more, at graduated rates.
  • Corporate tax increases: PROPOSED, NOT ENACTED in the 2026 session.

If you have been carrying a mental model in which a 16.8% New York rate is imminent, update it. The right way to think about a New York exit in late 2026 is that the current rate is already high enough to justify running the numbers, and that the pied-à-terre tax adds a new annual cost to the common "keep the apartment, change the domicile" plan.

Compare this to Florida:

  • State income tax: 0%
  • Capital gains tax: 0%
  • Estate tax: 0%
  • Inheritance tax: 0%

The Math: What This Means for Your Wallet

Income (single filer) NY State + NYC Tax (2026 schedules) If the 2% surcharge had passed (it did not) Florida Tax Annual Savings Today
$200,000 ~$18,645 (9.3%) ~$18,645 (no change) $0 ~$18,645
$500,000 ~$52,647 (10.5%) ~$52,647 (no change) $0 ~$52,647
$1,000,000 ~$106,277 (10.6%) ~$106,277 (no change) $0 ~$106,277
$2,000,000 ~$270,400 (13.5%) ~$290,400 (14.5%) $0 ~$270,400
$5,000,000 ~$676,200 (13.5%) ~$756,200 (15.1%) $0 ~$676,200

Method and caveats: figures are computed from the 2025 New York State and New York City tax rate schedules and the state's supplemental tax computation worksheets in the Form IT-201 instructions, for a single filer with no credits, treating the stated amount as New York taxable income. The third column models the proposed 2-percentage-point surcharge applied to income above $1 million; that surcharge was not enacted and the column is shown only so you can see the size of what was actually on the table. Your own liability depends on filing status, deductions, credits, and income composition.

Note what this table does not show: a 16.8% effective rate at $1 million. Effective rates in the low-to-mid teens are what high New York City earners actually pay, because the 10.9% state bracket does not begin until $25 million of taxable income. That is still a large number. Over a 10-year period at $2 million of annual taxable income, the state and city tax avoided by a properly executed Florida domicile change is roughly $2.7 million.

The Psychological Trigger

High taxes alone don't cause mass migration. New York has had high taxes for decades. What Mamdani's election created was a permission structure—a psychological tipping point where staying became the irrational choice.

Polling by J.L. Partners for the Daily Mail, conducted around the 2025 mayoral race, found that 9% of New York City residents said they would "definitely" leave and 25% said they would consider it. Treat those as stated intentions in a charged political moment, not as forecasts: survey answers about moving reliably overstate actual moves, and the 2024 Census flows showed New York-to-Florida migration falling, not rising.

The election did not create new incentives. It crystallized existing ones for people who had been running the numbers for years. But with the surcharge unenacted, the honest framing is that the tax case for leaving New York in 2026 is the same tax case that existed in 2024, not a new emergency.

Who's Actually Moving: The Demographic Reality

Forget the stereotype of retirees moving to Florida for golf and sunshine. The 2025-2026 migration wave is dominated by young, high-income professionals in their prime earning years.

The New Florida Migrant

  • Age: 26-44 (peak earning, family-forming years)
  • Income: $150,000-$500,000+ (upper-middle to high earners)
  • Profession: Finance, tech, entrepreneurship, remote-capable professionals
  • Family status: Mix of singles, young couples, and families with children
  • Motivation: Tax savings, quality of life, business opportunity—in that order

SmartAsset analysis of IRS migration data reveals a striking pattern: Florida is gaining 1,786 young wealthy households (ages 26-35, earning $200k+) per year, while New York is losing 345 in the same category. This isn't a temporary blip—it's a structural demographic shift.

Remote Workers & Digital Nomads

The post-pandemic remote work revolution unlocked Florida for location-independent professionals. A significant share of white-collar roles in tech, finance, and professional services now offer full remote options—a dramatic shift from pre-2020 norms.

Rule of thumb: A remote worker earning $200,000 saves roughly $18,645 annually by moving their domicile from New York City to Florida (single filer, 2026 rate schedules, standard deduction, before credits; New York State plus New York City resident tax per the table above), and more at higher incomes, assuming their employer allows full remote work. Many are doing exactly that, maintaining New York salaries while establishing Florida domicile in hubs like Miami, Tampa, and Jacksonville. For complete guidance, see our NY exit guide.

Mobile Professionals on Out-of-State Contracts

Consultants, contractors, and other professionals who work assignment to assignment are among the biggest winners from a Florida domicile, because their income follows the work while their tax home stays put.

Rule of thumb: A contract professional earning $150,000 as a New York City resident pays roughly $13,670 in combined state and city income tax (single filer, 2026 rate schedules, standard deduction, before credits), all of which can be eliminated by establishing a Florida tax home. Florida doesn't tax income earned on out-of-state contracts, making it a natural domicile for professionals who work assignment to assignment.

Who's NOT Moving

Not everyone can or will leave. Understanding who stays helps understand who goes:

  • Industry-dependent professionals: Wall Street traders requiring physical exchange presence, Broadway performers, certain legal and medical specialties
  • Real estate-locked: Those underwater on NYC property or unable to sell
  • Family obligations: Aging parents, custody arrangements, school commitments
  • Cultural attachment: Those for whom New York's specific amenities are irreplaceable
  • Lower earners: The tax differential doesn't justify moving costs for sub-$100k earners

The self-selection creates a concerning dynamic for New York: the most mobile, highest-earning residents leave, while those least able to leave (or least incentivized to) remain. This hollows out the tax base disproportionately.

Where the Money Is Flowing: County-by-County Breakdown

Not all of Florida is created equal. New York money flows to specific destinations based on income level, industry, and lifestyle preferences. Understanding these patterns reveals both opportunity and competition.

Southeast Florida: The Primary Destination

According to Q2 2025 data from the Miami Association of Realtors, New York counties (NYC, Nassau, Suffolk) are the #1 out-of-state origin for movers to the entire Southeast Florida region. Here's where they're landing:

Florida Destination Top NY Source Profile Price Point
Miami-Dade NYC (Manhattan, Brooklyn) International, cosmopolitan, Latin American business hub $800K-$5M+
Broward Suffolk, Nassau (Long Island) Families, suburban feel, mid-luxury $500K-$1.5M
Palm Beach Nassau County (North Shore) Ultra-wealth, established money, "Wall Street South" $1.5M-$20M+
St. Lucie Suffolk County (Long Island) Value seekers, emerging market, rapid appreciation $350K-$700K

Miami-Dade: The International Hub

Miami-Dade attracts the most cosmopolitan segment of New York migrants—those who value international connectivity, diverse culture, and business ties to Latin America. The average income of Miami-bound movers ($266,000) reflects the financial services and tech professionals driving this cohort.

Neighborhoods of choice: Brickell, Coconut Grove, Coral Gables, Miami Beach, Surfside

Why NYC transplants choose Miami: Direct flights to NYC (12+ daily), international airport, similar urban energy, diverse population, emerging tech scene

Palm Beach: Wall Street South

Palm Beach County has deliberately positioned itself as "Wall Street South"—a strategic campaign by the Business Development Board to attract financial services firms and their employees. The results are dramatic:

  • Citadel relocated headquarters from Chicago to Miami/Palm Beach
  • Elliott Management moved to West Palm Beach
  • Goldman Sachs, Blackstone, Apollo expanded Florida operations
  • Point72, Related Companies established significant Florida presence

The hedge fund migration has created a gravitational pull: when the billionaires move, their employees follow. When their employees follow, the service infrastructure expands. The result is a self-reinforcing cycle that has transformed West Palm Beach from a sleepy retirement community into a legitimate financial center.

Port St. Lucie: The Overlooked Hotspot

Here's the story most coverage misses: Port St. Lucie had the single largest migration inflow in Florida during Q2 2025.

This isn't Palm Beach money slumming—it's a distinct demographic:

  • Source: Primarily Suffolk County (Long Island) middle-class homeowners
  • Profile: Police, firefighters, teachers, nurses cashing out $800K Long Island homes
  • Value proposition: $400K buys a new construction 4BR in Port St. Lucie vs. a tear-down in Babylon
  • moveBuddha data: Port St. Lucie in-to-out ratio: +1.67, with 72.4% year-over-year increase

Port St. Lucie represents the middle-class version of the Mamdani Effect. These aren't millionaires fleeing the wealth tax—they're $150k-$250k earners who did the math and realized they could retire 10 years earlier in Florida than on Long Island.

📍 Emerging Market Alert: Ocala

According to moveBuddha's 2025-2026 forecast, Ocala has the highest in-to-out migration ratio in Florida at +3.09. While not a traditional NY-to-FL corridor, Ocala is attracting remote workers and early retirees seeking affordability. Watch this market.

Real Estate Impact: What Migration Means for Property Markets

When $9.2 billion in income relocates over five years, real estate markets respond. The NY-to-FL migration has reshaped South Florida property dynamics.

Price Appreciation: The Numbers

  • Palm Beach County median home price: Up 47% since 2020
  • Miami-Dade median condo price: Up 38% since 2020
  • Broward County median home price: Up 52% since 2020
  • Port St. Lucie median home price: Up 61% since 2020 (highest appreciation rate)

New York buyers are simultaneously cause and effect of this appreciation. They arrive with New York equity—selling $1.5M Brooklyn brownstones or $2M Long Island colonials—and pay cash in Florida markets. This injects liquidity, drives prices up, and attracts more buyers anticipating further appreciation.

Inventory Dynamics

The supply side tells an equally important story:

  • Luxury inventory ($1M+): Remains tight in Palm Beach, loosening slightly in Miami
  • Mid-market ($500K-$1M): Competitive, multiple offers common in desirable areas
  • Entry-level ($350K-$500K): Extremely tight in Port St. Lucie and emerging markets
  • New construction: Cannot keep pace with demand; waitlists common for premium developments

Investment Implications

For those considering Florida property as part of a domicile strategy:

  • Buy the domicile, rent the lifestyle: Establishing domicile requires residential address, not ownership. Consider your property strategy independently from your tax strategy.
  • Factor in insurance: Florida property insurance costs have increased 40%+ since 2020. Budget accordingly.
  • Understand HOA implications: Many desirable Florida communities have HOAs with significant fees and restrictions.
  • Consider timing: Prices have appreciated significantly. Don't overpay for domicile purposes alone.

2026 Outlook: What Happens Next

The Mamdani Effect is just beginning. Here's what the data suggests for the next 12-24 months.

Tax Timeline: What Actually Happened

  • Q1 2026: Mamdani took office and began the legislative push for his tax proposals, travelling to Albany to make the case.
  • Q2 2026: Both legislative chambers backed versions of tax increases on high earners; Governor Hochul opposed them and held that position through the budget.
  • May-June 2026: The FY2027 State Budget passed without the 2-percentage-point personal income tax surcharge and without the corporate tax increases, but with a New York City pied-à-terre tax on non-primary residences, effective for city fiscal years beginning July 1, 2026.
  • Now: No New York City millionaire surcharge exists. Any renewed attempt would require a future Albany session to authorize it.

The critical insight has changed. There is no rate cliff to beat, so timing should be driven by evidence quality, not urgency. A domicile change assembled over several deliberate weeks, with a severed or genuinely rented New York abode, contemporaneous day records, and a filed part-year IT-203, will survive an audit. One assembled in a panic weekend to beat a deadline that does not exist will not.

The "Silent Migration" Mechanism

Not everyone announces their departure. Many high-net-worth individuals execute what tax attorneys call "silent migration" -- a methodical New York to Florida domicile change that follows a well-established playbook:

  1. Establish Florida address (lease or purchase)
  2. Change driver's license and voter registration
  3. Maintain NYC pied-à-terre for "visits" (carefully tracking days)
  4. File Florida tax returns claiming domicile change
  5. Keep quiet about the move to avoid social/professional friction

This pattern means official migration statistics undercount actual domicile changes. Many "New Yorkers" are already Florida residents for tax purposes—they just haven't updated their social media.

Global Context: The Millionaire Migration

The NY-to-FL migration is part of a broader global pattern of high-net-worth individuals relocating tax residence, with Dubai, Singapore, and Portugal among the destinations most often cited for international flows and Florida the leading domestic destination for U.S. wealth. We previously quoted a specific worldwide millionaire-migration count here sourced to a wealth-management firm's press release; we have removed it because we could not verify the underlying methodology, and forecasts of this kind vary widely between publishers.

This creates both opportunity and competition. Florida is competing not just with New York for residents, but with international tax havens for globally mobile wealth. The state's zero income tax remains a powerful draw, but infrastructure, services, and quality of life must keep pace with demand.

Risks and Headwinds: Why Some Will Stay

Not everyone can or should move. Understanding the counterarguments creates a more complete picture.

Why New York Might Retain High Earners

  • Unparalleled density of opportunity: For certain industries (finance, media, fashion, theater), New York remains irreplaceable
  • Network effects: Relationships built over decades don't transfer easily
  • Cultural amenities: World-class museums, restaurants, entertainment—Miami is improving but isn't Manhattan
  • Education: NYC's specialized high schools, proximity to elite universities
  • Healthcare: Access to top specialists and hospitals
  • Four seasons: Some people actually like autumn in Central Park and don't want year-round summer

Florida's Challenges

  • Property insurance crisis: Costs have skyrocketed; some areas becoming uninsurable
  • Infrastructure strain: Roads, schools, and services struggling to keep pace with growth
  • Climate vulnerability: Hurricanes, flooding, rising sea levels are real long-term concerns
  • Cultural adjustment: Florida is not New York; some transplants struggle with the transition
  • Healthcare access: Specialist availability outside major metros can be limited

The Audit Risk

New York State aggressively audits domicile changes, particularly for high earners. Simply buying a Florida condo doesn't make you a Florida resident. You must:

  • Spend more days in Florida than New York (ideally under 183 days in NY)
  • Establish genuine ties (driver's license, voter registration, bank accounts, doctors)
  • Sever New York ties comprehensively
  • Maintain meticulous documentation

What to Watch: Leading Indicators for 2026

Track these signals to understand where the migration is heading:

Real Estate Signals

  • Cash buyer percentage: Rising cash purchases indicate NY equity flowing in
  • Days on market: Declining DOM signals demand outpacing supply
  • Price premiums for "turnkey": NY buyers pay more for move-in ready properties
  • Rental demand: Short-term rentals for "test drives" before purchase

Business Formation Signals

  • Florida LLC formations from NY principals: Business relocation precedes personal relocation
  • Office lease activity in Palm Beach/Miami: Financial services expansion
  • Job postings: Florida postings from NY-headquartered firms

Demographic Signals

  • Private school enrollment: NY families with school-age children enrolling in FL
  • Country club membership waitlists: Social infrastructure saturation
  • Synagogue/church membership: Religious communities report NY influx

Aaron L., a 33-year-old private equity associate at a mid-market firm in Midtown earning $475,000 base plus a projected $1.1M carry distribution in Q3 2026, came to YourTaxBase in early January 2026 with a clean exit window: his firm had a satellite office in Palm Beach, his role was pivoting toward portfolio company work that did not require Manhattan presence, and his fiancee's parents had recently relocated to Boca Raton. Stacked on his base salary, the carry would have fallen partly in New York's 6.85% state bracket and partly in the 9.65% bracket, with New York's tax-benefit recapture pulling his entire taxable income up to the top rate he reached, plus New York City's 3.876%. That put his New York state and city exposure on the carry alone at roughly $161,862: $119,226 of state tax plus $42,636 of city tax on the $1.1M slice stacked on top of the $475,000 base (single filer, 2026 schedules, standard deduction, before credits), an incremental rate of about 14.7% on that slice. (At the time he engaged us, the widely quoted alternative was a proposed 2-percentage-point city surcharge on income above $1 million; that surcharge was never enacted, and on his numbers it would have added roughly $11,500, not the $23,000 the "16.8%" headline implied.)

The 18-day Florida residency sprint we executed:

  • Day 1-3: Closed on a one-bedroom lease at a real Florida residential street address in West Palm Beach. Utilities (FPL electric, AT&T fiber) put in his name day 4. Two proofs of residential address generated immediately.
  • Day 5: Florida driver license issued at the FLHSMV West Palm Beach service center under §322.031. New York license retained for the duration of an active NY-issued REAL ID transition (no surrender required, but documented as the FL license becoming primary).
  • Day 6: Voter registration completed online through the Florida Division of Elections under §97.041. New York voter registration cancelled with the NYC Board of Elections.
  • Day 9: Declaration of Domicile filed under Florida Statutes §222.17 with the Palm Beach County Clerk via remote online notarization, recording fee $11.50.
  • Day 12: Manhattan studio apartment lease assigned to a new tenant with the landlord's consent; lease termination effective February 28, 2026. Furniture and the bulk of personal items shipped to West Palm Beach.
  • Day 14: Bank, brokerage, and credit-card addresses updated to the West Palm Beach address. Private equity firm payroll updated.
  • Day 18: Florida-based dentist, primary care physician, and credit union accounts established. Two pieces of mail received at the West Palm Beach address.

The fiancee co-relocated under the same domicile stack one month later. The wedding was held in Palm Beach in summer 2026 with both individuals already Florida domiciliaries of record.

Day-count discipline was structured around the New York 183-day rule under Tax Law §605 and 20 NYCRR §105.20. We capped his New York presence at 96 days for 2026 (well under the 184-day statutory residency line), used a contemporaneous spreadsheet plus EZ-Pass and credit-card receipts, and kept boarding pass records for every NY visit.

Year-one outcome:

  • New York state and city tax on the $1.1M carry distribution: $0, sourced to Florida domicile, supported by a Declaration of Domicile filed eight months pre-distribution, severed Manhattan lease, voter registration, driver license, and 96 New York days.
  • New York source tax on the $475,000 base salary: approximately $63,000 in New York-source wages for the 96 days physically worked from the Manhattan office, paid to a New York employer.
  • Net first-year New York state and city tax avoided on the carry distribution: approximately $161,862 ($119,226 state plus $42,636 city on the $1.1M slice stacked on the base, single filer, 2026 schedules). No rate escalation materialized, because the proposed surcharge did not pass the 2026 Albany session.
  • Final NY IT-203 part-year return filed with a clearly stated departure date of January 9, 2026, starting the 3-year NYS DTF audit clock.

The case illustrates the post-Mamdani template: severance of the Manhattan abode (the most-litigated NY domicile factor under Matter of Hoff), Florida ties stacked under §222.17, §322.031, and §97.041, day discipline well under 184 days, and a clean part-year IT-203 to start the audit window running.

Frequently Asked Questions

How many New Yorkers are moving to Florida?

50,661 people moved from New York to Florida during 2024, per the U.S. Census Bureau's 2024 American Community Survey 1-year state-to-state migration flows released January 21, 2026 (±6,714). That is down from 71,138 in the 2023 vintage. Roughly 28,080 moved from Florida to New York in 2024, so the net was about 22,600 in Florida's favor.

What is the Mamdani Effect?

The "Mamdani Effect" is the label commentators applied to the surge of New York buyer interest in South Florida real estate around Zohran Mamdani's November 2025 election as NYC mayor, and to the expectation that his proposed 2-percentage-point surcharge on income above $1 million would push the combined state and city top marginal rate to about 16.8%. That surcharge was not enacted. New York City cannot raise its own income tax without Albany's authorization, and the 2026 session ended without it. The combined top marginal rate remains 14.776%.

How much can I save by moving from New York to Florida?

Savings depend on income level. On the 2026 rate schedules (single filer, standard deduction, before credits), a filer earning $500,000 owes roughly $52,647 in combined state and city income tax and one earning $1,000,000 owes roughly $106,277. Both go to zero in Florida. Over 10 years at the same income that is roughly $526,000 to $1.06 million, before investment returns.

Where are New Yorkers moving in Florida?

The primary destinations are Miami-Dade (cosmopolitan, international), Palm Beach (ultra-wealthy, financial services), Broward (families, suburban), and increasingly St. Lucie (value-seeking middle class). Port St. Lucie had the highest migration inflow in Q2 2025.

How do I establish Florida domicile legally?

Florida domicile requires demonstrating intent to make Florida your permanent home. Key steps include: obtaining a Florida driver's license, registering to vote in Florida, filing a Declaration of Domicile with your county, establishing Florida bank accounts, and spending more time in Florida than any other state. See our Florida Residency Guide for complete instructions.

Will New York audit my domicile change?

If you're a high earner (particularly $1M+), New York State may audit your domicile change. The state uses a "primary factors" test examining home ownership, business ties, time spent, and "near and dear" items. Meticulous documentation and genuine ties to Florida are essential. See our guide: How to Legally Leave New York Taxes.

Is Florida's housing market overheated?

Prices have appreciated significantly since 2020 (40-60% depending on area). However, continued migration, limited inventory, and structural demand suggest prices are more likely to plateau than crash. Insurance costs and interest rates are the primary risks to monitor.

What about Florida's hurricane risk?

Hurricane risk is real and should factor into location decisions within Florida. Coastal areas face higher insurance costs and storm surge risk. Inland areas like Orlando, Ocala, and Port St. Lucie face lower (but not zero) risk. Building codes have improved significantly since Hurricane Andrew (1992).

Can I keep a New York apartment and still be a Florida resident?

Yes, but carefully. Statutory residency requires both prongs: a permanent place of abode in New York and more than 183 days in the state. Keep your presence to 183 days or fewer, tracked contemporaneously. On the abode prong, the Department's Nonresident Audit Guidelines apply a more than 10 months maintenance standard for tax years beginning in 2022 or later, replacing the older "substantially all of the year" formulation. Many successful domicile changes convert the New York apartment to a genuine arm's-length rental or sell it outright. As of city fiscal years beginning July 1, 2026, keeping a non-primary New York City residence can also trigger the newly enacted pied-à-terre surcharge.

Should I rush a move before Mamdani's taxes take effect?

There is no rate increase to beat. The proposed surcharge required Albany authorization and did not pass the 2026 session; as of August 2026 nothing has been enacted. Move on the merits of the current rate differential and on your ability to build a clean evidentiary record, not on a deadline. Filing a final part-year New York IT-203 with a stated departure date is what starts the audit window running.

I'm a remote tech worker making $250K—does Florida make sense for me?

If your employer allows full remote work, yes. At $250,000 of income, you're paying roughly $25,027 annually in combined New York State and New York City income taxes (single filer, 2026 rate schedules, standard deduction, before credits; exact amount depends on filing status and deductions). Moving to Florida eliminates this entirely: same salary, same Zoom calls, different tax jurisdiction. The key is genuinely relocating: spending 183+ days in Florida, documenting your domicile change, and understanding that New York also examines intent, home ownership, and business ties beyond just day counts. See our NY exit guide for complete requirements.

I split time between NY and FL for work—how does domicile work?

Establish Florida as your tax home and you pay zero state income tax regardless of where your assignments are—including New York contracts. Key requirements: maintain a permanent Florida address, return between assignments, and keep Florida as your "regular place of abode." Watch out for New York's 183-day rule (spending 183+ days there triggers statutory residency) and their "permanent place of abode" test. Proper documentation is essential—keep travel records, lease agreements, and return-trip receipts. This is general information, not individualized tax advice; consult a tax professional for your specific situation.

I'm an RVer or full-time traveler—why is Florida domicile popular?

Rule of thumb: Florida is the #1 domicile state for RVers and full-time travelers because it combines zero state income tax with straightforward residency establishment and no requirement to be physically present year-round. Establish domicile with a qualifying address, obtain your driver's license and voter registration, then travel freely. Unlike California (which may claim domicile based on historical ties) or New York (aggressive exit audits), Florida genuinely lets you go. This is general educational information; consult a tax professional before making domicile decisions.

Final Thoughts: The Mathematics of Migration

The New York-to-Florida migration isn't about politics, weather, or lifestyle preferences, though those factors matter. At its core it is a mathematical decision driven by a real, currently-in-force tax differential: an effective combined New York State and New York City rate in the roughly 10% to 13.5% range for high earners, against 0% in Florida.

Zohran Mamdani's 2025 election put that math on the front page, and one Miami developer reported more than $100 million in New York-buyer contracts in the months leading up to the vote. But the specific policy that generated the "16.8%" headline did not become law: Albany declined to authorize the city surcharge in the 2026 session. What did become law is a New York City pied-à-terre tax on non-primary residences, which cuts against the popular strategy of changing domicile while keeping the apartment.

So the honest version is less dramatic and more useful. There is no deadline. The differential that made a Florida domicile worth considering in 2024 is still the differential today, and the thing that determines whether you keep the savings is not how fast you move but how well you document it: sever or genuinely rent the New York abode, keep contemporaneous day records under 184, stack the Florida ties under §222.17, §322.031, and §97.041, and file the final part-year IT-203.

The numbers are clear. Just make sure they are the current ones.

Frequently asked questions

How many New Yorkers are moving to Florida in 2026?
The most recent published figure is 50,661 people moving from New York to Florida during 2024, from the U.S. Census Bureau's 2024 American Community Survey 1-year state-to-state migration flows released January 21, 2026 (margin of error ±6,714). That is down from 71,138 in the 2023 vintage. In the same 2024 data, 28,080 people moved from Florida to New York, so New York's net loss to Florida was roughly 22,600. Notably, New Jersey (56,799) narrowly overtook Florida as the single largest destination for New York movers in the 2024 data. Longer-term, the Citizens Budget Commission found a net 30,000 New York City residents moved to Miami-Dade and Palm Beach counties in the five years through 2022, taking about $9.2 billion of income with them.
How much can I save by moving from New York to Florida?
Savings depend on income level. On the 2026 rate schedules, a single filer earning $500,000 owes roughly $52,647 in combined New York State and New York City income tax, and one earning $1,000,000 owes roughly $106,277 (standard deduction, before credits). Both drop to zero in Florida, which charges 0% state income tax on wages, business profits, capital gains, dividends, and retirement distributions under Article VII §5 of the Florida Constitution. The proposed 2-percentage-point New York City surcharge on income above $1 million was not enacted, so do not model your savings on a 16.8% rate.
What is the NY statutory residency 183 days rule?
New York Tax Law §605(b)(1)(B) and 20 NYCRR §105.20 impose statutory residency on anyone who spends more than 183 days in New York during a tax year and maintains a permanent place of abode in New York. Both prongs must be met. Any part of a day in New York counts as a full day. The NYS Department of Taxation and Finance treats this as a bright-line rule, and routinely uses cell-tower records, EZ-Pass logs, credit-card geolocation, and dedicated residency auditors to challenge day counts. Falling 184 days converts you back to a full-year resident regardless of where your domicile is.
What does Matter of Hoff (DTA No. 850209) mean for my New York exit?
The New York Tax Appeals Tribunal decision in Matter of Hoff, issued October 9, 2025, upheld a deficiency of approximately $60,000 against a couple who had Florida driver licenses, voter registration, and a recorded Declaration of Domicile but kept a New York home and meaningful New York ties. The Tribunal applied the clear-and-convincing-evidence standard for changing domicile, not the §605(b) 183-day statutory-residency test. The Tribunal's holding: paperwork creates the appearance of a domicile change, but substantive ties (where you actually live, where your near-and-dear personal items are, where your active business is, and where your family spends time) control. The lesson is to sever, not just supplement.
What are the Florida domicile requirements for a New Yorker establishing residency?
The Florida domicile requirements stack is: a real Florida residential street address (lease or owned, not a PO Box or CMRA mail drop), a Florida driver license obtained within 30 days under Florida Statutes §322.031, voter registration under §97.041, vehicle registration if applicable, and a Declaration of Domicile filed with the county clerk under Florida Statutes §222.17. Florida residency rules favor substantive ties: utility bills, banking relationships, doctors and dentists, professional licenses, and where your family spends the school year. There is no minimum day count for Florida, but the New York 183-day rule will impose one anyway.
How do I file an affidavit of domicile in Florida from New York?
The Florida domicile form, formally a Declaration of Domicile under Florida Statutes §222.17, is filed with the clerk of the circuit court in the Florida county where you live. The form is a sworn, notarized statement listing your prior state, your Florida address, and your declaration that Florida is your permanent home. Recording fee is approximately $10. Most Florida counties accept remote online notarization, so applying for Florida residency does not require an in-person courthouse trip. The Declaration is dated, public, and sworn, which is exactly the kind of contemporaneous evidence the NYS DTF expects to see in a residency audit file.
Can I keep a New York apartment and still be a Florida resident?
Yes, but carefully, and the New York "permanent place of abode" rule under 20 NYCRR §105.20 is the most-litigated piece of state residency law. To keep a NYC apartment without triggering statutory residency, you must spend fewer than 184 days in New York and either (a) the apartment is not suitable for year-round use, or (b) you have not maintained the apartment for more than 10 months of the year (the standard the Department's Nonresident Audit Guidelines apply for tax years beginning in 2022 or later, replacing the older "substantially all of the year" formulation), or (c) you can demonstrate the abode is actually unavailable to you. Many successful New York exits convert the NYC pied-à-terre to a true rental with a property manager, or sell. Matter of Hoff (October 2025) is a cautionary tale on keeping the apartment. Note also that the FY2027 State Budget created a New York City pied-a-terre tax on non-primary residences effective July 1, 2026, which adds an annual carrying cost to keeping a New York City apartment you no longer live in.
Should I rush a move before Mamdani's taxes take effect?
There is no rate increase to beat. The proposed 2-percentage-point New York City surcharge on income above $1 million requires State legislative authorization, and the 2026 Albany session ended without it. Proposals can return in a future session, but as of August 2026 nothing has been enacted, and you should treat any advice built on an imminent 16.8% combined rate as out of date. The durable reasons to move deliberately rather than in a panic are unchanged: a domicile change built over a few careful weeks documents better than one built in a weekend, and filing a final part-year New York IT-203 with a clearly stated departure date starts the NYS DTF audit window running (it never starts if you fail to file).
What are the Florida residency rules for remote workers leaving New York?
Florida residency for tax purposes works the same for remote workers as for any other domiciliary: it is intent-based, anchored by substantive ties under Florida Statutes §222.17, §322.031, and §97.041. The wrinkle for remote workers is the New York "convenience of the employer" rule under New York Tax Law §605, which can source wages to New York if you work for a New York employer and your remote-work location is for your convenience rather than the employer's necessity. To avoid this, make sure your employer formally documents that your Florida-based work is required for business reasons, not just personal preference. Many post-Mamdani exits include a formal employer letter to that effect.
Will the NYS DTF audit my domicile change after I move to Florida?
High earners (especially $500K+ and anyone with a stock sale or business sale in their departure year) should expect an NYS DTF residency audit. The Department uses dedicated residency auditors, cell-tower records, EZ-Pass logs, credit-card geolocation, social media, and IRS data cross-references. The standard audit window is 3 years from the date you filed the part-year IT-203, but never starts running if you fail to file the final part-year return. Substantive ties (Florida home, Florida driver license, Florida voter registration, severed New York ties, sold or rented New York apartment, Florida-based doctors and bank) and meticulous day tracking are the audit-defense stack. See Matter of Hoff (DTA No. 850209) for the Tribunal's most recent statement of what is and is not enough.

California's Two New Taxes for 2027: What SB 122 and SB 125 Actually Cost You (and the One Tax Cut Sacramento Can't Block)

On June 29, 2026, Governor Newsom signed a budget that creates two new taxes effective January 1, 2027: a sales tax on software and SaaS (SB 122) and a redesigned health plan tax (SB 125) that is expected to flow into private premiums.
