We believe there are three unintended consequences from states raising tax rates on the rich. First, some rich residents sell their homes and leave the state; second, those who stay in the state report less taxable income on their tax returns; and third, some rich people choose not to locate in a high-tax state. Since many rich people also tend to be successful business owners, jobs leave with them or they never arrive in the first place. This is why high income-tax states have such a tough time creating net new jobs for low-income residents and college graduates.

Those who disapprove of tax competition complain that lower state taxes only create a zero-sum competition where states “race to the bottom” and cut services to the poor as taxes fall to zero. They say that tax cutting inevitably means lower quality schools and police protection as lower tax rates mean starvation of public services.

They’re wrong, and New Hampshire is our favorite illustration. The Live Free or Die State has no income or sales tax, yet it has high-quality schools and excellent public services. Students in New Hampshire public schools achieve the fourth-highest test scores in the nation — even though the state spends about $1,000 a year less per resident on state and local government than the average state and, incredibly, $5,000 less per person than New York.
