Each Student SSN that has a value on Form 8863, must not be the same as that in another Form 8863 for the same tax year.
An individual tax return receives reject code F8863-528-03 / F8863-528-04 when a student's social security number has been reported on another tax return claiming education credits for the same tax year.
The reject will indicate the last four digits of the student's SSN. To resolve this reject, the education credit for this student needs to be removed. Once removed, the return can be resubmitted.
