My son is NOT my dependent and NOT a qualifying relative (due to his age/income and not being a FT student). He was a half-time student his final spring semester and he got a 1098-T for $5,000. This is the first year he has not been my dependent so there are new wrinkles.

I took a 529 w/d for the exact amount of his tuition plus qualified educ expenses that I paid ($13,000), so the full 529 w/d is non-taxable to me. The basis portion (non-taxable because it is not earnings) of the w/d was $6,000. (He is the beneficiary of the 529. He has no scholarships.)

Can he take the American Opportunity Tax Credit (AOTC), (subject to the $4k limit and any other adjustments made by TT based on his income etc) ?

I am thinking because the $5k Basis portion of the 529 withdrawal is greater than his $4k AOTC limit, his AOTC eligibility should not be hindered by the 529 w/d on my return? (Since there is no "double dipping", correct? Meaning, I received no tax reduction on the $5K basis portion.)

just to clairfy: the last paragraph should read 6K basis portion of the 529 w/d, not 5K basis portion. (5K was the 1098-T tuition).

Q. Is the $6000 basis portion of the 529 distribution non-taxable because it is not earnings?

A. Yes, but it is not "deducted off the top". The taxable portion of the earnings is determined by a ratio of the non qualified portion of the distribution, if any, to the total distribution.

Q. Can he take the American Opportunity Tax Credit (AOTC)?

A. Yes, but the qualified portion of the 529 distribution will be reduced by the amount of expenses (most likely $4000) used to claim the AOTC, making part of the distribution (w/d) taxable on your return.

Q. I am thinking because the $6k Basis portion of the 529 withdrawal is greater than his $4k AOTC limit, his AOTC eligibility should not be hindered by the 529 w/d on my return? (Since there is no "double dipping", correct?

A. No. The simple explanation is: it doesn't work that way. See the math below. There is double dipping. But, you two get to decide how to allocate the expenses between you for the best outcome (him using $4000 for the AOTC is almost always the best way to go).

$13,000* in educational expenses (including room & board).

-$4000 used to claim the American Opportunity credit on student's return

=$9000 expenses Can be used against the 1099-Q (on your return)

Box 1 of the 1099-Q is $13,000

Box 2 (earnings) is $7000

9000/13000=69.23% of the distribution is qualified, so 30.77% is non qualified. This means 30.77% of the earnings are taxable

30.77% x 7000= $2154. There is $2154 of taxable income on your (the recipient of the distribution) return.

Multiply that by your marginal tax rate (e.g. 12% x 2154 = $258 in tax) to compare to the $2500 AOTC your son (probably) gets.

* It wasn't clear whether your total expenses are $13,000 or $18,000. You taxable income will be a little more with an $18K distribution.

@Hal_Al as always, I enjoy and appreciate your analysis. How can the expenses (the $4000) be allocated? Parent can't take AOTC because student is not a dependent, right?

@MNski also, son can only take AOTC if it was not used in 4 of the prior years. it is possible, since he was a student for the spring semester of 2025, you used all four years of eligibility for his fall freshman year (2021) and then 2022, 2023, 2024, which means there is no 2025 eligiblity.

@NCperson My assumption was that the student qualified on his own, for the AOTC and even if ineligible for the refundable portion, had enough tax liability to get the non refundable portion. Good catch on the 4 times limit. The family should still come out better if he can only claim the Lifetime Learning Credit (LLC) but nowhere near as lucratively as the AOTC (I didn't do the actual math).
