How would a millionaire's tax affect the Massachusetts economy? It would shrink it, according to a report from the Fiscal Alliance Foundation and The Beacon Hill Institute.
The two right-of-center organizations released a study earlier this month that shows that if Massachusetts voters approve the so-called Fair Share Amendment — which looks headed for the November 2022 general election ballot — it will result in job loss. The proposal would increase the marginal tax rate on household income over $1 million in Massachusetts from 5 percent to 9 percent — an 80 percent increase.
