You must enter either the last 5 digits of your Social Security Number or your full Student ID, AND your full first and last name in order to be authenticated in this system. Note, the Student ID method will only work if your school has reported your Student ID to us. Many do not. Further, you must enter your name as it was provided to us by your school. If you’ve had a name change, you should use the name that was in use at the end of the tax year.
