Migration to and from Vermont, by age group, 2020 and 2021

About a decade ago, the IRS also began tracking migration by the age and income of the primary tax filer. For 2021, Vermont saw a net increase in all age brackets except filers under age 26. (Again, the IRS reports only the primary filer’s age, not the ages of everyone who migrated in and out.) In 2021 Vermont also netted an increase in the number of tax filers in all but the lowest income bracket (less than $10,000 a year). The biggest gains occurred in the highest tax brackets, as has been true over the last decade.

But the age and income information is separate from information about which states people move to or from. So we can know either the age and income of filers or the states they left, but not both at the same time. For example, we know that 1,100 filers with incomes of $200,000 or more moved to Vermont in 2021, but we don’t know where they came from. And we can’t tell where the 35-44-year-olds went after leaving Vermont.
