Answer
Do not complete GTP until you have received all of your forms. If you believe that you should have received a Form W-2 or Form 1042-S and you have not yet received such form, do not contact GTP Support, you must contact the institution that made payments to you and request the form. Generally, Forms W-2 are issued by the Payroll Department; generally Forms 1042-S are issued by the Tax or Payroll Department. If the form was sent to the wrong address, the institution will provide you with a new copy of the form. You should NOT complete GTP until you have ALL of your forms; doing so, may mean that you will file an incomplete and incorrect tax return.
