Living in New York and working in New Jersey.. how do I report the New Jersey taxes on my New York state return

There is a form (I believe it is titled Resident Tax Credit) that allows you to claim the taxes you paid in NJ as a credit against your NY tax liability.

It will NOT completely offset your NY taxes (because NY state tax rates are higher than NJ), but it WILL cut it down somewhat.
