My wife lives and works remotely in NJ, we've been asking her company to stop withdrawing NYS taxes because we live and work in NJ , they refused. They said the company has an office in NYC and that office address is on her contract. She never went to that office and we also filed IT-2104.1 form. They still charge her NY tax. I guess it doesn't matter for NYS tax department where you live, as long as you work for a company with a NYC office they'll charge you NY taxes and force you to file a nonresident IT-203 form.
