Hi, I have a client that lives in NJ and works in the NJ office of his firm. He works one day per week in the firms NYC office. Should his firm be withholding NY tax? Short background is he historically worked in the NYC office but when COVID hit he was working from home (resides in NJ) most of the time. Starting 2021 he was able to get a transfer to NJ as his primary office. He still works one day per week in the NYC office, and still works from home (NJ) 2 days per week. So he is essentially working in NJ two days per week, from home in NJ two days per week, and one day in NYC.
Thanks!
