Yes.
Any reported tuition assistance or outside aid will be factored into your financial aid award. Your tuition assistance will take the place of loan funding, which decreases the total amount of loans you will need to repay once you are done with school.
Since federal financial aid can come with annual and lifetime borrowing limits using tuition assistance can also help reduce the chances of you running out of federal aid prior to completing your program. If you are reporting these funds after you are awarded federal funding, it may result in a reduction of your federal student loans to ensure we do not award you more than your Cost of Attendance.
