Will I get double taxing when I move to Michigan and my employer is in CA?

Hi all,

 

Due to my company's announced WFH until July 2021, I am thinking of moving to Michigan for at least the first 6 months for 2021 to stay with my family.  My employer is in CA.

 

Will I get a double tax on income and RSU for the move?  Is taxation complicated?

 

Thanks!
