Since the beginning of New Jersey's chronic fiscal crisis in the early-2000s, there's been an unending argument over raising taxes on high-earners to mitigate the budget crisis. The argument over high-brackets exists in periods of New Jersey's growth, like in the mid-2010s and Phil Murphy's first three budget proposals, and in times of recession, like the Great Recession and today's Coronavirus Recession.
There are some New Jerseyans who are flat-out conservative and believe creating high brackets is "punishing success" and that it would deter entrepreneurism, but the more significant argument is between moderates who oppose raising rates out of a pragmatic belief that high rates will induce millionaires to leave, and progressives, who say that higher-brackets are necessary to reduce racial and social inequality and argue taxes are marginal costs to already-rich people and that interstate moves are motivated by the lifestyle changes, the weather, and family considerations.
In tracking this argument, something I see as incomplete is its it's always framed as people leaving New Jersey, or outmigrating from New Jersey, or an "exodus from" New Jersey. Chris Christie simply said, "tax them and they will leave." This framing elides the other half of the equation; which is how do high-taxes affect the location decisions of businesses and people in other states who could have moved to New Jersey?
Perhaps we don't consider "New Jersey Avoidance" because it's difficult to measure and is a non-event that doesn't generate headlines, but it's a phenomenon that can be inferred by how New Jersey's wealth, income, population, and jobs growth lag national averages.
David Tepper's departure, Mercedes-Benz's departure, Honeywell's departure etc generated headlines, but no New Jersey newspaper is going to write a story about a pharmaceutical company opening a lab in Massachusetts, or a bank expanding in Salt Lake City, Dallas, Florida, or Nashville. Yet these events in other states are important for understanding New Jersey's current economy because a generation ago, those firms would have expanded in New Jersey.
Referring to the millionaire population of New Jersey, an historical examination of the IRS's Statistics of Income confirms that yes, New Jersey's millionaire population has seen apparently large growth (+214% since 2001), but that growth is nowhere near the national average (which was +330%) and is the fourth lowest in the US. Thus, even if NJ's millionaire population grows, it's not a slam-dunk evidence that millionaires don't care about taxes and there is seemingly an avoidance effect happening that may be more significant than departures.
The IRS Statistics of Income confirm that New Jersey's distribution of income is highly unequal.
Of New Jersey's $426.8 billion in total income in 2018, $60.6 billion came from 22,420 returns of more than $1 million, and another $33.3 billion came from filers reporting income of $500,000-$1 million. (See Note 1)
Thus, 22% of NJ's income is attached to only 1.6% of tax returns, and is even more concentrated if you calculated inequality of residents, since the poorest-of-the-poor don't file tax returns.
To some people, that existence of inequality ends the argument: New Jersey must raise income taxes to reduce inequality. Since New Jersey's wealthiest are presumably disproportionately white, and its poorest are disproportionately Black and Latino, that only heightens the imperative to raise taxes on the wealthy.
Since the revenue raised by tax increases could pay for various desired services like teacher pensions, state-funded PreK, K-12 school aid, direct tax rebates, and build a rainy-day fund, raising taxes on the wealthy is a moral and fiscal absolute.
But moral absolutes are a funny thing, because not everyone's moral absolutes are the same. Rich people who aren't persuaded that they must pay 10.75% of their income to the State of New Jersey don't need to stay here, nor are high-earning people contemplating a move to New Jersey obligated to come here. Although the State of New Jersey is obligated to pay over $200 billion in debt, New Jerseyans as individuals aren't obligated to pay anything and don't need to stay here.
Phil Murphy has also said that "millionaire flight is a myth" and actively campaigns for higher income taxes, but his statements are sparse compared to the New Jersey Policy Perspective, an NJEA-funded activist group based in Trenton.
The NJPP is a major proponent of raising taxes on the wealthy and has written multiple reports (or "reports") arguing that it's a "myth" that millionaire outmigration and that there's been an exodus of wealth from NJ.
For instance, there's this 2016 piece "The 'Exodus' is More Like a Trickle" written by Sheila Reynertsen.
Notice how Reynertsen, just like conservatives, frames the issue as people leaving NJ. There is no contemplation of an avoidance effect.
Several rigorous statistical studies of interstate moving patterns confirm that there is no meaningful correlation between state taxes and interstate moves. For example, a new long-term study of top income-earners found that the vast majority of millionaires don’t move to avoid state taxes. Another study specifically looked at the impact of New Jersey’s 2004 enactment of a higher tax rate on incomes of more than $500,000 and concluded that “the effect of the new tax bracket is negligible overall. Even among the top 0.1 percent of income earners, the new tax did not appreciably increase out-migration.”More importantly, the amount of new revenue gained from the tax change dwarfed the tax payments that would have been made by those few who left. The estimated revenue lost was less than 2 percent of the overall revenue gained. In other words, New Jersey did not lose money by increasing income tax rates on the wealthiest households.
The argument that the elderly, in particular, flee taxes by moving to lower-tax or no-tax states is also not supported by the empirical evidence. The patterns of state-to-state movement among the elderly have remained relatively consistent over time, even as state tax policies toward the elderly changed significantly across states. If older people who leave New Jersey are heading to popular retiree destinations regardless of tax policy, there is no reason to offer them tax breaks in the hopes that they will stay.
The NJPP's #1 piece of evidence that high-income outmigration is a "myth" is that despite New Jersey having multiple income tax increases in the last 20 years, the number of millionaires in New Jersey has grown, in raw numbers and as a percentage of the population.
|Corzine's Millionaire's Tax Took Place at the Time of a Recession, so the NJPP's Claim that Only Recessions Cause a Drop in High Income Residents is Statistically Unsupported.|
So how can there be an outmigration problem if the population of rich people keeps growing?
The problem exists because New Jersey's economic growth is insufficient to relieve its budget disaster. The evidence of a problem comes when you just apply inflation and look at other states.
$500,000 in 1994 = $800,000 in 2015. Inflation isn't a obscure thing, but the NJPP ignores it.
And the interstate comparison matters
The NJPP is a progressive information filtering service, not an objective think tank, and context is to be ignored, manipulated, and switched in the service of whatever progressive cause the NJPP is advocating for. When it suits the NJPP, they use nationwide and regional comparisons, but when interstate comparisons would undermine the progressive case, the NJPP doesn't.
The IRS's Statistics of Income does not go as far back as 1994, and it does not provide data on $500-$1 million earners and >$1 million earners for the years 2002-2009. A comparison of 2001 and 2018 data reveals how much the growth of NJ's high-income population has lagged the nation's.
To put it another way:
Because if you look at the increase in the number of millionaires nationwide, NJ's increase has lagged the national average. New Jersey's population of $1 million earners only grew at 76.5% of the national rate.
This isn't proportional with NJ's low overall population growth rate. NJ's tax return growth was 93% of the national average for 2001-2018.
NJ's increase in people earning over $1 million was the fourth smallest in the US.
New Jersey's increase in people earning $500,000-$1,000,000 is the fifth smallest in the country.
It's true that NJ's overall population has grown very slowly, but NJ's share of the total population didn't show as large a lag against national growth. In 2001, New Jerseyans had 3.1% of total tax returns in 2001 and 2.9% of total returns in 2018. NJ's growth in overall population is in the bottom ten, but not 4th-5th from last.
It is difficult to disentangle overall slow economic growth from low growth of high-income populations, but I think I think they are co-dependent. I cannot prove how much of this effect is due to taxes, but other high-income tax states like New York and Connecticut have also seen slow growth, although, to be fair, Iowa, Minnesota, and California have gotten strong growth.
I am not aware of polling specifically of ultra-rich people on residential decisions, but there is a lot of evidence they are more fiscally conservative than non-rich people. A large body of polling evidence shows regular people care about taxes as well. A 2014 Monmouth University poll found that New Jerseyans who wanted to leave were much more motivated by cost of living and taxes than any other factor, with higher-income people more likely to say taxes. Gallup has found that people in high-tax states were much more likely to want to leave than residents of moderate-tax and low-tax states (residents of moderate-tax states were not more likely to want to leave than residents of low-tax states).
Based on the conservativism of high-income people and polls of the general population, I think one can infer that high-income people can be intolerant of taxes enough to take taxes into account in their location decisions.
Can Income Migrate?
A secondary progressive claim is that income can only rarely leave a state.
The vast majority of people actually don’t take their income with them to a new state – because they can’t. When people make an interstate move, they usually leave their job to take another, and the income they made in their previous job typically goes to the person who replaces them. That state income essentially stays put, which explains why New Jersey’s overall income reported each year grew significantly at the same time we “lost” that $18 billion.For NJ's total $426.7 billion in total income in 2018, $289.1 billion was "Salaries & Wages," or 68%. The rest is interest, capital gains, S-corp profits, dividends, royalties, pensions, Social Security, alimony etc. I don't know what percentage Sheila Reynertsen considers a "vast majority," but 32% of NJ's income is non-salary income and that amount can't be dismissed.
The same holds true for business owners if they leave the state. The money their business made goes to the new owner of the business if the old owner sold it, or other in-state businesses that pick up the customers of the one that left. If a doctor or a plumber or the owner of a restaurant leaves New Jersey, the patents and clients and customers don’t leave too.
For those moving out of state upon retirement, it is equally misleading to claim that New Jersey’s economy loses income equal to the person’s pre-retirement salary, because their income also would have declined if they had retired in New Jersey.
Whatever threshold the NJPP uses for the adjective "vast majority," what is indisputable is that higher income people have more non-salary income.
- the person becomes a remote worker.
- the person moves to another state and becomes a commuter to a NJ-based job.
- the business itself moves.
acceptability presents a challenge to New Jersey. High-income workers are more likely to be able to work remotely than middle-income and low-income workers. Given how low NJ's income growth already is, if remote working frees only a few thousand high-income workers from New Jersey or allows New Yorkers and Philadephians to "suburbanize" outside of the region to Florida or to resort towns, remote working stands as a problem for New Jersey after the Coronavirus-flight from New York City ends.

Note 1: NJ's Adjusted Gross Income is $406 billion. I'm using total income in this blog post because I want to discuss what percentage of it is possessed by various income strata. If I considered the deductions people qualify for like the Adjusted Gross Income uses, it would not give as accurate an amount.
HOWEVER, the claims in this blog post about a relatively slow-growing millionaire population is still accurate since it is based on IRS historical Statistics of Income, which are real numbers, not estimates.
