How much capital gains tax do I owe to Michigan if I moved mid-year?

[mark-rundle]

I moved from Michigan to Washington in July 2017. In December I received a capital gains distribution from a mutual fund I owned all year. When filing my Michigan taxes, do I owe capital gains taxes on: 

(a.) The entire amount since I owned the mutual funds while a Michigan resident 

(b.) The fraction of the year I lived in Michigan times the entire amount

(c.) Nothing, since the distribution was made after I ended my residency in Michigan

[KatherineC · Accepted solution]

Your investment income is taxed by the state you are living in when you receive the income. 

So the capital gains distribution would not be taxable to Michigan.
