This State Has More Millionaires Per Capita Than Any Other

America is often described as a patchwork of cultures and economic strata, and nowhere is that more visible than in how sharply prosperity clusters within certain states. The gap in wealthy household concentration from one state to the next is not subtle. It is wide, measurable, and the product of decades of geographic, economic, and tax-policy decisions playing out in real time.

Some states have dramatically more millionaire households than others. Narrowing the data to a single metric makes it possible to identify the state with the greatest millionaire density: the highest share of million-dollar-net-worth households relative to its total number of households.

California, New York, and Connecticut would all be reasonable guesses. Each has globally recognized wealth centers, elite universities, and deep financial-services industries. The correct answer, however, is none of them.

Lush Wealth in the Garden State

The American state with the most millionaires per capita is New Jersey. According to Statista data sourced from Kiplinger, the Garden State has roughly 246,000 households with a net worth of at least $1 million, translating to 9.76% of all New Jersey households. California and New York both have far larger absolute counts of millionaire households, but their enormous populations dilute those numbers on a per-household basis.

New Jersey’s lead is narrow. Maryland finished second with 9.72% of households crossing the million-dollar threshold, while Connecticut came in third at 9.44%. The Garden State still edged out 49 others to claim the top spot, including several states widely assumed to be the country’s primary wealth magnets. A separate 2026 ranking by Phoenix Marketing International, which measures investable assets and excludes primary-residence equity, places New Jersey even higher, at 10.8% of households, with Maryland at 10.4% and Connecticut at 10.3%.

Being millionaire-dense and being millionaire-friendly are two very different things, and New Jersey illustrates that tension more clearly than any other state.

Geography Attracts Prosperity

New Jersey’s wealth concentration owes a great deal to location. Sitting squarely between New York City and Philadelphia, the state puts two of the country’s largest labor markets within commuting distance. For a high-net-worth household seeking space, strong public schools, and relative quiet, suburban New Jersey delivers many of the economic benefits of those metro areas without the density or price tag of living inside either city.

New Jersey is home to 15 Fortune 500 companies on the 2026 list. Johnson & Johnson (NYSE:JNJ | JNJ Price Prediction) leads the state’s contingent, ranked 42nd nationally on $94.2 billion in 2025 revenue. Merck (NYSE:MRK) ranks 66th, Prudential Financial (NYSE:PRU) 74th on $60.8 billion in revenue, and Bristol Myers Squibb (NYSE:BMY) 96th. Together, New Jersey’s 15 Fortune 500 companies generate roughly $442 billion in combined revenue and employ close to 961,000 people. For executives and senior professionals in pharmaceuticals, financial services, and healthcare, New Jersey is a practical home base, close to major employers yet outside New York City proper.

Property values add another layer. According to the Tax Foundation’s 2026 data, New Jersey carries an effective property tax rate of 1.88% on owner-occupied housing, tied with Illinois for the highest in the nation. The average annual property tax bill crossed $10,000 for the first time in 2024, landing at a record $10,095, a 3% jump from the prior year. Those bills are steep by any measure, but the same elevated home values that drive them also push homeowners’ net worth upward, particularly for households that have held property for decades.

A Taxing Financial Issue

Despite its millionaire-density title, New Jersey’s tax environment poses a genuine challenge for wealthy residents. Recent policy changes have made that pressure more acute.

Since 2020, any New Jersey resident with annual taxable income exceeding $1 million has faced what is informally called a “millionaire’s tax,” carrying a state income tax rate of 10.75% on those earnings. That rate applies to income between $1 million and $5 million. Income above $5 million was already taxed at 10.75% before the 2020 expansion took effect, placing New Jersey’s top rate among the highest of any state in the country.

The burden on real estate transactions has grown as well. Legislation signed by Governor Murphy on June 30, 2025, and effective July 10, 2025, overhauled the state’s “mansion tax” in two significant ways. Payment shifted from buyers to sellers, and the old flat 1% rate gave way to a tiered structure. Sellers now pay 1% on properties between $1 million and $2 million, with rates climbing progressively to a cap of 3.5% on sales above $3.5 million. The updated tax is projected to generate more than $550 million annually for state programs.

Tax pressure is already visible in migration patterns. According to the Tax Foundation’s analysis of IRS data, New Jersey lost a net $2.56 billion in adjusted gross income to interstate migration during the 2022-2023 period, ranking fourth among states for filer losses, behind only California, New York, and Illinois. That figure represents an improvement from the record $5.27 billion net AGI loss the state posted for 2021-2022, but the cumulative drain has been substantial. Florida and Texas, both with no state income tax, remain the top destinations for departing wealth, and both have seen their millionaire populations grow fastest in absolute terms in recent years.

The broader trajectory is worth noting. Research tracking millionaire population trends since 2019 shows that New Jersey is one of five states where the total count of millionaire households has actually declined on a net basis, even as its per-capita share remains the highest in the nation. That combination, a top ranking in density alongside a shrinking absolute pool, captures the tension at the core of New Jersey’s wealth story. Many millionaires stay because of family ties, career anchors, and unmatched access to the New York City metro. Others are recalculating whether the trade-off remains worthwhile. For now, the Garden State holds its title, but the forces working against it are real and have been building for years.

Editor’s note: This pass added Prudential Financial (No. 74, $60.8 billion in revenue) to the list of New Jersey Fortune 500 companies and included the combined revenue and employment figures for all 15 state-based firms. It also added context from 2026 research showing New Jersey is among five states where the total count of millionaire households has declined since 2019 even as per-capita density remains the highest nationally, and noted that Florida and Texas have recorded the fastest absolute millionaire-population growth due to in-migration.
