States with no income tax have seen their gross state product grow faster than states with an income tax, in addition to no-tax or low-tax states experiencing positive in-migration. Repeal of the personal income tax will make Wisconsin’s business climate instantly more competitive in the Midwest, help address worker shortages, and unlock Wisconsin’s economic potential. In the absence of eliminating the income tax, Wisconsin should reduce and flatten the rate to remain competitive with other Midwest states that have lowered rates and enacted other tax reforms.
