I worked for a company which is based in California, but I was based in NY (I worked remotely). In Sept of 2013 I moved from NY to TX, but my employer kept withholding NY income tax after the move. Between Jan to Sept 2014 this employer (which was based in CA) withheld NY state income tax even though I lived in Texas. I left the company in Sept of 2014. I am not sure the correct way to file this. My prior company won't correct the W2 and now claim I never told them I moved... Am I going to have to sue them to fix this, or is there some way I can just file my NYS tax forms and get back the taxes paid?
