State tax filing

Thanks so much for your explanation - This means that my second employer has underestimated the state  + local MA tax withheld. The main difference is coming from the 3.2% the local county tax in MD.

 

My other question: If I'm 100% remote despite that my employer headquarter is at MA. I can only file state tax to my resident state. How the withheld can be redirected to MD?
