It is clearer than ever that the U.S. Tax Cuts and Jobs Act of 2017 made high tax states less competitive with low tax states. But instead of using this moment to reflect on how taxes influence behavior, politicians in places such as Connecticut, New York, New Jersey and Illinois are inexplicably doubling-down by threatening to raise taxes on their citizens even more.
Until politicians start to understand the benefits of economic incentives and an equitable tax system, expect these high-tax states to continue down the road to financial depredation as taxpayers pick up and leave in greater numbers. To review, up until a couple of years ago, individuals could deduct every dollar of state or local taxes paid from their federal return. This had the effect of shielding taxpayers from the full consequences of tax-and-spend policies in high tax states. But under the new tax laws, the deductible amount is capped at $10,000. This change has been characterized as soaking the rich, but it soaks a lot of other people, too. It’s not hard to exceed the cap. Even middle-class families can do it in high tax states.
I predicted in December 2017 that the cap on so-called SALT deductions would result in “a population migration so large that it could result in profound economic and social changes.” It’s happening.
Connecticut lost the equivalent of 1.6% of its annual adjusted gross income, as those who moved out of the state had an average income of $122,000, which was 26% higher than those migrating in.
New York’s annual net loss was the highest, with a net $8.4 billion leaving the state. Exiting incomes of $19.1 billion were replaced by people who brought in $10.7 billion less in income.
Illinois and New Jersey were next with net outflows of $4.8 billion and $3.4 billion.
In high-tax states, the combined federal, state, and local tax burden can approach or exceed 50%, even after taking into account lower marginal rates. There is something magic about the 50% number that causes people to rethink their finances. I would characterize a combined tax burden of over 50% as immoral, on the grounds that it is simply unfair to take more than half of what somebody makes.
Rational economic actors seek to lower their tax bills. There are frictional costs associated with moving, but people will do the mental math and figure out if the long-term gain from a lower tax bill exceeds the short-term pain from moving. Blue state governors have mostly refused to acknowledge the migration. When they have, they attribute it to things like the weather.
Mostly, they have responded to complaints of high taxes with higher taxes. Which is also not irrational. If your state experiences out-migration and your tax base erodes, first-order thinking would lead you to believe that you can plug the hole with higher sales taxes and fees, as Connecticut is doing.
Alternatively, a forward-thinking governor could instead drastically reduce the size and scope of government and lower the tax burden on, yes, even rich taxpayers.
In spite of overwhelming evidence that taxes influence behavior, there are plenty of tax-migration deniers. They say high taxes pay for top-notch services of the kind you get in wealthy blue-states.
I talk to the folks who move to Myrtle Beach, South Carolina, which is where I live and is the 2nd fastest-growing metropolitan area in the country. It has nice weather, yes, but more crucially, it has a low cost of living and an exceptionally low property tax burden that averages about $1,500 for a typical house. That is the selling point, and nothing else. The new arrivals are not much interested in the services.
