Study Dispels Myth about Millionaire Migration in the US

Study dispels myth about millionaire migration in the US., EurekAlert: The view that the rich are highly mobile has gained much political traction in recent years and has become a central argument in debates about whether there should be "millionaire taxes" on top-income earners. But a new study dispels the common myth about the propensity of millionaires in the United States to move from high to low tax states.

"The most striking finding in our study is how little elites seem willing to move to exploit tax advantages across state lines," said Cristobal Young, an assistant professor of sociology at Stanford University and the lead author of the study. ...

In any given year, Young and his fellow researchers found that roughly 500,000 individuals file tax returns reporting incomes of $1 million or more (constant 2005 dollars). From this population, only about 12,000 millionaires change their state each year. The annual millionaire migration rate is 2.4 percent, which is lower than the migration rate of the general population (2.9 percent). The highest rates of migration are seen among low-income tax filers: migration is 4.5 percent among people who earn around $10,000 a year. ...

The study finds that family responsibilities are a key factor that limit migration among top-income earners. "Very affluent people are much more likely to be married and to have school-age children, which makes moving more difficult," Young said. ...

While millionaire migration is extremely limited, there is a grain of truth in the worries about millionaire tax flight, the study finds. "When millionaires do migrate, they are more likely to move to a state with a lower tax rate, and that state is almost always Florida," Young said. ...

"My guess is that if Florida established a 'millionaire tax,' elites would still find Florida appealing because of its climate and geography -- and patterns of elite migration wouldn't really change," Young said. ...

The study also looked at the millionaire population along the borders between states with different tax rates. "In these narrow geographic regions, you would expect millionaires to cluster on the low tax side of the border, but we see very weak evidence of this," Young said.

As for policy implications, Young said "millionaire taxes" result in minimal tax flight among millionaires and help states raise revenue to improve education, infrastructure, and public services, while reducing inequality.

"Our research indicates that 'millionaire taxes' raise a lot of revenue and have very little downside," Young said.
