On net, in every year from 2001 through 2016, Minnesota lost residents to other states. This was a source of much discussion in our state, prompting fears of slower economic growth and a lost congressional seat.
So there was some celebration when, in 2017 and 2018, the Census Bureau found that there were net in-migrations of people into Minnesota from other states, in the net amounts of 7,941 and 6,769, respectively.
Unfortunately, that uptick of migration into Minnesota has proved to be temporary. Figures for 2019 show that in-migration dropped essentially to zero, a positive net of 65 people. And another new data set provides more cause for concern.
The Internal Revenue Service maintains a database that allows us to track the movements of individuals between states. Unlike the Census Bureau's numbers, the IRS database supplies both age and income information about interstate migrants. This gives us a picture of which people we are attracting, and which are we driving away.
As the Center of the American Experiment noted in our previous report "Minnesotans on the Move to Lower Tax States," the IRS database showed that our state had been losing residents to other states, on net, since 2001-02 — matching the Census Bureau numbers. It also showed that, as of 2016, the outflow of residents went overwhelmingly to lower-tax states.
The IRS database has just been updated with the addition of two more years of statistics on the movement of taxpayers across state lines, covering the years 2016-17 and 2017-18. Unfortunately, these new data show that the trend that existed as of 2016 continues: Minnesota gains low-income residents from other states, but loses middle- and upper-income residents, generally to lower-tax states.
In fact, the IRS data show that Minnesota, on net, lost $900 million in income to other states between 2016 and 2018. Specifically, in 2016-17, the state lost $223 million in adjusted gross income reported by tax filers who moved in and out of Minnesota — the least, adjusted for inflation, since 1995-96 — before seeing the net loss increase again to $673 million in 2017-18.
This is down from the peak outflow of 2013-2014, when former Gov. Mark Dayton's tax hike apparently prompted an egress of taxpayers from the state. As Dayton himself said, discussing tax breaks intended to encourage investment, "Incentives do make a difference."
