Thank you for your reply! Though I think I made a mistake as I reexamined things.
Does it change anything if my company's headquarters (and hence the address on the W2) is in Michigan? So I live in WI, the rest of my team and division is in NJ but the company is out of MI?
Yet they company withdrew NJ taxes. Funny enough, i just went and checked my latest pay stub and I'm not paying NJ state taxes anymore.
Edit: Yep, it's a mistake. Company mistakenly withdrew NJ taxes for half of last year which is why my state taxes for NJ are equal to half of my total wages.
