State tax filing
On your nonresident New Jersey return, duplicate wages would be the amount for New York in Box 16 of your W-2. Therefore, please check the box for the NY state wage amount on the page Let's Confirm Your Taxable State Wages. I have attached a screenshot below for additional guidance.
It is important to note that New Jersey state wages are often higher than federal or New York wages because New Jersey taxes some benefits that the federal government and New York do not.
