NY is currently forcing employers to withhold income tax for people in NJ who have not been in NY in the last 18 months. I know quite a few companies who told their employees they will not stop withholding NY taxes from their income, and the issue is currently making its way through the courts.

Edit: I missed this update, but apparently the SC told NH they cannot sue MA, so as far as I now, NY and MA have been cleared to continue collecting income tax from people not working in their states.
