State taxes

Hello,

 

I have a child who moved from Michigan to New Mexico in October.

My child earned no income in New Mexico, only in Michigan before moving.

 

Do I need to file a New Mexico state return for him? Should I file a New Mexico state return for him? My default would be to file the regular Michigan return, since that's where all of the money was earned, as I don't believe that would have any impact on the amounts due or refunded.

 

Thanks for any comments.
