My company is in NY but I relocated to NC and am working from home for the NY company. Should I have NY & NC taxes withheld? Or one or the other?. Thank you!

I work for a law firm in NY (not NYC).  It does not have any offices in NC.  I am working remotely from my home for work provided to me by the NY office.  I need to know if I should have my boss start taking out NC taxes as well as NY taxes and if I will be taxed double for the same income for each State.  I currently just have NY taxes coming out.
