AS far as I can see checking online..... payroll contributions to a 401k in NY ARE deferred income for NY residents. ROTH 401k contributions wouldn't be, but that's just normal behavior.
..what state's don't allow a state income deduction for 401k contributions? PA, NJ....might be a very few others (ignoring states without an income tax)
