Deductions & credits

Is she your dependent?  If so, the AOC, Form 1098-T and other education expenses and credits are entered on your tax return not hers.

If she is not a dependent but under the age of 24 then she must have taxable compensation to be eligible for AOC.

If she is age 24 or older then no taxable income is required but she is only eligible for a reduced AOC of $1,000
