This post explores the difference among tax policies in Massachusetts, New Hampshire, and Florida in order to explain the increasing amount of Massachusetts residents who are migrating from the state. Tax-friendly policies are very alluring to Massachusetts residents, seeing as the state is actually increasing the personal income tax rate rather than try to lower taxes, as both New Hampshire and Florida have done.

Over the last 25 years, Massachusetts has consistently lost taxable income, especially to Florida and New Hampshire, via out-migration of the wealthy, according to a new Pioneer Institute study. In “Do The Wealthy Migrate Away From High-Tax States? A Comparison of Adjusted Gross Income Changes in Massachusetts and Florida,” Pioneer Institute Research Director Greg Sullivan and Research Assistant Andrew Mikula draw on IRS data showing aggregate migration flows by amount of adjusted gross income (AGI). The data show a persistent trend of wealth leaving high-tax states for low-tax ones, especially in the Sun Belt.
