New Jersey’s top income tax rate is 10.75%. It applies to every dollar of income above $1 million and it has no ceiling. Governor Phil Murphy signed the increase in 2020, raising the top rate from 8.97% — the so-called “millionaire’s tax” that New Jersey politicians had debated for years and finally enacted. Combined with federal rates, a New Jersey resident earning $5 million in a given year faces a marginal rate on the top dollars approaching 50%.
That would be enough on its own. But New Jersey has layered onto its income tax some of the highest property taxes in the country — the average effective property tax rate in New Jersey is the highest of any state, with many affluent communities in Bergen, Morris, and Somerset counties posting effective rates above 2% on properties worth several million dollars — alongside a real estate exit withholding requirement that catches departing residents off guard, and an audit posture with access to New York’s enforcement infrastructure on the other side of the Hudson.
The result is a state that is, by most objective measures, one of the most expensive places in the United States to be wealthy. And the wealthiest New Jersey residents are leaving. The question is whether you understand the full picture of what you are leaving — and what doing it correctly requires.
The 10.75% Rate and What It Actually Costs
New Jersey’s income tax has seven brackets. The top rate of 10.75% was established at $1 million in income, but below that threshold the rates are not gentle. Income between $500,000 and $1 million is taxed at 8.97%. Income between $75,000 and $500,000 is taxed at rates ranging from 5.525% to 6.37%.
For a high earner in New Jersey — a hedge fund manager, a corporate executive with equity compensation, a real estate developer, a business owner taking distributions — the effective state income tax rate on total income is substantial even before reaching the 10.75% bracket.
What makes New Jersey’s income tax especially expensive for certain earners is its treatment of capital gains. Unlike some states that offer preferential rates on long-term capital gains, New Jersey taxes capital gains as ordinary income. A $10 million gain on the sale of a business or a long-held investment portfolio is subject to New Jersey income tax at whatever marginal rate applies — up to 10.75% on the portion above $1 million.
For a New Jersey resident holding $50 million in appreciated securities with a low cost basis, the New Jersey tax on a full liquidation is in the neighborhood of $5 million. That is a state tax bill, on top of federal capital gains tax, that could be eliminated entirely by establishing a genuine Florida domicile before selling.
The New York Problem
A substantial portion of wealthy New Jersey residents work in New York City. They have for decades. The commute from Summit, Montclair, Short Hills, and Ridgewood to Midtown Manhattan is as familiar as any commute in the country.
The tax consequence is severe. New York State taxes income earned by nonresidents from New York sources at the same rates that apply to New York residents — up to 10.9% at the top bracket. New York City layers on a city income tax of up to 3.876% for residents, but even nonresidents who work in the city pay a commuter tax. The result: a New Jersey resident who works in New York City is effectively paying both New Jersey income tax on their total income and New York income tax on wages earned in the city.
The two states have a credit mechanism that prevents full double taxation, but the credit is not complete, and the combination of a New York workday requirement and New Jersey residency produces a total state and local tax burden that is among the highest in the United States for high earners. For someone earning $3 million in a year from a combination of New York salary and New Jersey-based investment income, the combined state and local tax cost is well above $300,000.
Florida has no state income tax. There is no commuter tax, no tax on investment income, no tax on capital gains. The savings for a dual New York/New Jersey-burdened earner who genuinely establishes Florida domicile are immediate and substantial.
The Estate Tax Situation
New Jersey’s estate tax has had a complicated recent history. The state eliminated its estate tax for decedents dying on or after January 1, 2018, after years of pressure from wealthy residents and estate planning attorneys who argued it was accelerating departures. Prior to that, New Jersey had an estate tax with a $675,000 exemption — effectively capturing estates that were entirely exempt at the federal level — that was widely acknowledged as punitive for a state competing for wealthy residents.
The estate tax repeal was real, and it removed one of the most visible and symbolic pressure points. But New Jersey retains an inheritance tax, which is a different levy. Unlike an estate tax assessed on the decedent’s estate, New Jersey’s inheritance tax is assessed on the beneficiary based on their relationship to the deceased. Class A beneficiaries — spouses, children, grandchildren, parents — are exempt. Class C and Class D beneficiaries face rates up to 16%. For wealthy individuals with complex estate plans involving trusts, business interests, or transfers to individuals outside the immediate family, the inheritance tax remains a meaningful cost.
More practically, the elimination of the estate tax removed a current cost but did nothing to address the income tax, property tax, and exit withholding environment that drives most departures. For people making decisions about where to domicile for the next twenty years, New Jersey’s inheritance tax and property tax trajectory matter more than the estate tax repeal.
The Real Estate Exit Withholding
This is the provision that surprises New Jersey residents most when they try to leave.
When a nonresident of New Jersey sells New Jersey real property, the state requires that a portion of the sale proceeds be withheld at closing as an estimated tax payment. But here is the provision that catches people: when a current New Jersey resident sells their primary residence as part of a move out of state — establishing themselves as a New Jersey nonresident as of the transaction date — they are subject to the same withholding requirement.
The amount withheld is 8.97% of the gain or 2% of the total consideration, depending on the circumstances. On the sale of a $3 million home with $2 million in embedded gain, this withholding can amount to $60,000 or more, held by the state until you file a New Jersey nonresident tax return and reconcile the actual tax owed.
This is not technically an “exit tax” in the way California’s proposed departure tax would function. You will eventually get excess withholding back — if you file correctly and your actual New Jersey tax liability is lower than the withholding. But the cash flow disruption at the moment of sale is real, the paperwork requirement is burdensome, and the label “exit tax” has stuck in popular usage because that is more or less what it feels like to someone selling a New Jersey home as part of a departure.
For wealthy residents with New Jersey real estate holdings — whether a primary residence, vacation property, or investment properties — the exit withholding requirement is a procedural hurdle that must be planned for. It is manageable with the right accounting and legal team. It is not manageable as a surprise.
The IRS Migration Data: New Jersey Is Losing the Wealth Race
The IRS publishes annual state-to-state migration data derived from tax returns. For New Jersey, the pattern is consistent and unambiguous: the state loses more adjusted gross income to out-migration than it gains from in-migration, and the gap is large.
Florida is the primary destination. Year after year, New Jersey shows one of the largest net AGI outflows to Florida in the country. The people leaving are not, on average, lower earners. They are the taxpayers who generate a disproportionate share of the state’s income tax revenue. A state with a progressive income tax depends heavily on its highest earners, and it is the highest earners who have the most incentive — and the most resources — to leave.
New Jersey’s population as a whole has been relatively flat, but the demographics of who is staying and who is going matter. When a $5 million earner departs to Florida, New Jersey’s annual income tax revenue from that individual drops from roughly $500,000 to zero on Florida-sourced income. When a $50,000 earner departs, the loss is roughly $2,700. The departing high earner’s fiscal impact is not proportionate — it is structural.
New Jersey budget analysts and fiscal policy researchers have noted this pattern for years. The state’s response has generally been to dismiss the behavioral response to tax increases as overstated — a position that becomes harder to sustain when IRS migration data shows the AGI departures accelerating in the years following rate increases.
Who Has Already Left: The David Tepper Precedent
The most significant and widely discussed New Jersey departure in recent memory is David Tepper, founder of Appaloosa Management, one of the most successful hedge funds in history.
Tepper moved from New Jersey to Florida in 2016. At the time, his net worth was estimated above $10 billion, and he was arguably New Jersey’s single largest individual income taxpayer. The New Jersey budget office publicly acknowledged that his departure meaningfully impacted state revenue projections — a rare admission that a single individual’s tax decision was large enough to register in a state budget.
The reason was straightforward: Tepper’s income in certain years was in the billions, driven by his share of Appaloosa’s profits. A top New Jersey income tax rate of 8.97% at the time of his departure (since raised to 10.75%) applied to essentially all of it. The annual income tax savings from establishing Florida domicile were, by any estimate, in the hundreds of millions of dollars. Over the time horizon of a long investment career, the value is incalculable.
Tepper moved Appaloosa Management’s headquarters to Miami. He bought property in Miami Beach. He relocated his professional and personal life in a way designed to be defensible — because he knew New Jersey would scrutinize it. The Tepper departure became a reference point for New Jersey budget discussions and, simultaneously, a template for other high-net-worth New Jersey residents considering the same move.
He was not alone. The hedge fund and private equity community in New Jersey — concentrated in Short Hills, Summit, and the broader Route 78 corridor — has been thinning for a decade. Family offices have relocated. Managing directors and general partners with the income profiles and autonomy to choose their residence have done the math and reached the same conclusion Tepper reached. The professional community that remains in New Jersey is increasingly the portion tied to New York employment, physical proximity to clients, or genuine preference for the area.
New Jersey’s Division of Taxation: More Sophisticated Than You Think
New Jersey’s Division of Taxation is not as large or as aggressive as California’s Franchise Tax Board. But it is more capable than many departing residents expect, and it has a structural advantage that matters: proximity to and coordination with New York State’s audit apparatus.
New York State has one of the most systematic and adversarial residency audit programs in the country. New York auditors count days with extreme precision. They issue subpoenas for credit card records, EZPass data, cell phone records, and iCloud location history. They interview witnesses. They analyze patterns in security badge swipes, brokerage records, and real estate transactions. New York’s audit program has, over decades, developed detailed methodology for distinguishing genuine New Jersey residents from New Yorkers who claim New Jersey domicile to avoid New York taxes.
That methodology and those enforcement relationships do not stop at the Hudson. New Jersey’s Division of Taxation cooperates with New York, shares audit findings, and has access to the same categories of financial records. A high-net-worth individual who departs New Jersey may find that the documentation scrutiny they face from New Jersey is informed by the same analytical framework that New York has refined for its own purposes.
Additionally, New Jersey has a specific incentive to pursue departures: the state’s fiscal situation is tight, its pension obligations are enormous, and the taxpayers most worth pursuing are exactly the high-income individuals who have departed. The revenue at stake in each case is large enough to justify substantial audit investment.
The practical implication: you should assume your departure will be audited. Not reviewed — audited. The question is not whether it will happen but whether your documentation is ready when it does.
Why Florida Beats the Alternatives
New Jersey residents who decide to leave have options. Pennsylvania is adjacent and has a flat 3.07% income tax — low relative to New Jersey, but not zero. Nevada is no-income-tax but geographically inconvenient. Texas is no-income-tax and large, but its culture and climate attract a different profile. Wyoming and South Dakota offer favorable tax treatment with virtually no residency audit posture — but also with minimal infrastructure for the professional and personal life of a high-net-worth individual.
Florida wins for New Jersey residents for reasons that are partly financial and partly practical.
The Tax Profile
Florida has no state income tax, no estate tax, no gift tax, no wealth tax, and no capital gains tax. These are not marginal improvements over New Jersey — they are the elimination of an entire category of state tax cost. For a New Jersey resident earning $5 million per year, the income tax savings from a genuine Florida domicile are approximately $500,000 annually. For someone with a large investment portfolio they plan to liquidate, the savings on capital gains alone can be measured in the millions per transaction.
There is also no serious political movement in Florida to change this. Florida’s constitution makes enacting a state income tax exceptionally difficult — it requires a constitutional amendment. The state’s reliance on sales tax, tourism revenue, and property tax creates a fiscal structure that does not depend on income tax. This is not a policy that could reverse in the next legislative session. It is structurally durable.
The Geography
For New Jersey residents, Florida’s geography is the right answer in a way that Nevada or Wyoming is not. Miami is a three-hour direct flight from Newark. Fort Lauderdale is three hours from JFK. Palm Beach is accessible from every major Northeast airport with multiple daily flights. This matters for people who maintain professional relationships in the Northeast, own properties there, or simply have family in the region. The trip from South Florida to the New York metropolitan area is easier than the trip from Nevada or Wyoming by a significant margin.
A departure to Florida does not require severing the Northeast connection entirely. It requires restructuring it — which is a different and more manageable thing.
The Community
South Florida has more former New Jersey residents per square mile than anywhere outside New Jersey. Palm Beach County, Broward County, and Miami-Dade have decades of history as destinations for New Jersey and New York departures. The social infrastructure is real: communities of people with the same professional backgrounds, the same cultural references, the same preferences for coastal living.
This community matters not just for quality of life. New Jersey’s Division of Taxation looks at the totality of your Florida life when auditing a departure. A documented community membership — social organizations, civic involvement, medical providers, professional relationships — is evidence that your Florida life is genuine and not a legal construct. A neighborhood full of other people who made the same decision ten years ago and built full lives is useful context for a tax auditor.
The Asset Protection Angle
Florida’s homestead exemption provides some of the strongest creditor protection for primary residence equity of any state in the country. For a wealthy individual navigating litigation exposure, business risk, or the natural liabilities of a high-net-worth life, Florida’s homestead protection for an unlimited-value primary residence is a meaningful additional benefit that compounds the tax advantages.
The Practical Reality of a New Jersey Departure
A move from New Jersey to Florida requires doing more than buying a condominium in Palm Beach and filing a change of address. The Division of Taxation will look at whether you actually left. If the facts are mixed — if you spend forty nights in New Jersey with family in the first year after your claimed departure, maintain close ties to your prior accountant and attorney, retain country club memberships, or leave a spouse in the New Jersey home — you have a problem that no amount of Florida paperwork solves.
The documentation requirements for a successful departure are the same as those that apply in any state with a meaningful residency audit program: a contemporaneous, day-by-day record of where you actually were throughout the year. Not a reconstruction built from receipts and calendar exports after an audit notice arrives. A continuous, GPS-verified record created passively, before you had any reason to expect scrutiny.
New Jersey auditors have access to the same categories of records that New York auditors use. They will look at your credit card transactions by geography. They will look at EZPass tolls. In contested cases, they have access to cell phone carrier data. They will ask about medical appointments, club memberships, and where your personal property is kept. The burden in practice falls on you to demonstrate you left — thoroughly, consistently, and across the full range of life activities.
The 183-day threshold matters. But it is not just a day count. Auditors look at whether the days in Florida reflect genuine habitation of a new home, or whether they reflect an artificial pattern constructed to reach a number. Building a real Florida life — not just the paperwork of one — and documenting it continuously is how a departure withstands scrutiny.
How Southbound Helps
The most common reason a New Jersey departure fails under Division of Taxation review is documentation. Most people file the right paperwork — they get a Florida driver’s license, update their voter registration, establish banking and professional relationships. What they cannot produce, years later, is a credible contemporaneous record of where they actually were, day by day, across the year in question.
An auditor asking for a day-by-day account of your location two years after your departure is asking for something almost no one can reconstruct accurately from memory and paper records. A day count built from old calendar entries, credit card statements, and remembered flight itineraries is a reconstruction. New Jersey auditors know what reconstructions look like. They are a weak defense.
A continuous, GPS-verified record of your daily location, built passively from the day you established your Florida domicile, is a completely different posture. It is the record of someone who understood what was at stake and documented it correctly from day one.
Southbound builds that record automatically. The app runs in the background on your iPhone, logging whether each day is spent in Florida or outside it, using iOS’s significant-location-change system — battery-efficient, passive, no manual check-ins required. Every day is logged with GPS coordinates and accuracy data. Your location history is stored in your personal iCloud account and never on Southbound’s servers. We cannot see your data. It is yours.
The Departure Budget — the central feature on the Southbound dashboard — shows you exactly how many days you can still spend outside Florida and remain on track for your 183-day target. For someone managing time across New Jersey, New York, Florida, and other locations throughout the year, that number tells you at a glance whether a proposed trip fits your annual plan. You will know before you book whether you have the budget to make the trip. There are no surprises in December.
When your Division of Taxation audit information request arrives — potentially two or three years after your claimed departure date — you will have a clean, exportable log of every day, GPS-verified, timestamped continuously from the beginning. That record is the difference between a defensible position and an expensive, uncertain fight. Build it from day one, before you need it.
