Revenge of the Laffer Curve

Steve Moore and Art Laffer have an excellent column in today's Wall Street Journal. They explain that high-tax states drive repel entrepreneurs and investors, leading to a pronounced Laffer Curve effect. Productive people either leave the state or choose to earn and report less taxable income. And because growth is weaker than in low-tax states, there also is a negative impact on lower-income and middle-class people:

Here's the problem for states that want to pry more money out of the wallets of rich people. It never works because people, investment capital and businesses are mobile: They can leave tax-unfriendly states and move to tax-friendly states. ...Updating some research from Richard Vedder of Ohio University, we found that from 1998 to 2007, more than 1,100 people every day including Sundays and holidays moved from the nine highest income-tax states such as California, New Jersey, New York and Ohio and relocated mostly to the nine tax-haven states with no income tax, including Florida, Nevada, New Hampshire and Texas. We also found that over these same years the no-income tax states created 89% more jobs and had 32% faster personal income growth than their high-tax counterparts. ...Dozens of academic studies -- old and new -- have found clear and irrefutable statistical evidence that high state and local taxes repel jobs and businesses. ...Examining IRS tax return data by state, E.J. McMahon, a fiscal expert at the Manhattan Institute, measured the impact of large income-tax rate increases on the rich ($200,000 income or more) in Connecticut, which raised its tax rate in 2003 to 5% from 4.5%; in New Jersey, which raised its rate in 2004 to 8.97% from 6.35%; and in New York, which raised its tax rate in 2003 to 7.7% from 6.85%. Over the period 2002-2005, in each of these states the "soak the rich" tax hike was followed by a significant reduction in the number of rich people paying taxes in these states relative to the national average.

Interestingly, the Baltimore Sun last week published an article noting that the soak-the-rich tax imposed last year is backfiring. There are fewer rich people, less taxable income, and lower tax revenue. To be sure, some of this is the result of a nationwide downturn, but the research cited by Moore and Laffer certainly suggest that the state revenue shortfall will continue even after than national economy recovers:

A year ago, Maryland became one of the first states in the nation to create a higher tax bracket for millionaires as part of a broader package of maneuvers intended to help balance the state's finances and make the tax code more progressive. But as the state comptroller's office sifts through this year's returns, it is finding that the number of Marylanders with more than $1 million in taxable income who filed by the end of April has fallen by one-third, to about 2,000. Taxes collected from those returns as of last month have declined by roughly $100 million. ...Karen Syrylo, a tax expert with the Maryland Chamber of Commerce, which lobbied against the millionaire bracket, said she has heard from colleagues who are attorneys and accountants that their clients moved out of state to avoid the new tax rate. She said that some Maryland jurisdictions boast some of the highest combined state and local income tax burdens in the country. "Maryland is such a small state, and it is so easy to move a few miles south to Virginia or a few miles north to Pennsylvania," Syrylo said. "So there are millionaires who are no longer going to be filing Maryland tax returns."

With President Obama proposing higher tax rates for the entire nation, perhaps this is a good time to remind people about the three-part video series on the Laffer Curve that I narrated. If you have not yet had a chance to watch them, the videos are embedded here for your viewing pleasure:
