What is AOTC
AOTC is short for American Opportunity Tax Credit. It provides a $2500 tax credit for each of four years of the community/undergraduate education. Even if you have no tax liability, you might still be eligible to receive a portion of the $2500 credit back in what's called refundable credits.
What are the income phaseouts
The credit starts getting phased out at 80k (single) or 160k (MFJ). It's fully phased out at 90k (single) or 180K (MFJ)
I'm over the phase out limit. What can I do?
The rest of this covers this question. Similar to a back door Roth, the idea of the back door AOTC is to provide the AOTC benefit to your family but it requires a circuitous route to do so.
The basic idea works like this: while you personally are not eligible for the AOTC because of the income limits, your student might be. However, your student cannot claim the credit if you claim the student as a dependent on your return. So, first off, you need to not claim the student as a dependent. Note, it doesn't matter that you are eligible to claim the student, simply do not claim the student.
Next, with rare exceptions, your student will only be eligible for the non-refundable portion of the AOTC. This means that your student will need tax liability of at least 2500 (line 24 of the 1040) to take full benefit of the AOTC. For most students with part-time jobs, getting 2500 of tax liability via earned income is difficult because the standard deduction is so high.
In order to achieve $2500 of tax liability, the student will likely need to do it via unearned income. This is where "kiddie tax" can work to your benefit. If you have stock in a taxable account that has gains in it, gift that stock to the student, and then have the student sell the stock, and then use the proceeds to pay the tuition bill. The "kiddie tax" will have that stock sale be taxed at your tax rate and the resulting sale will generate tax liability.
For those who are worried about gifting stock to a child, you can wait until the last minute to gift this stock. E.g., if tuition payments are due on July 15, you could gift the stock on July 12, sell on July 13, and pay the school on July 15 with the settled funds. If you are still concerned about the funds being accessible to the child for even a day, you may be able to use an UTMA account for this (depending on the age of majority in your state).
How much should you gift and how much LTCG should be in the gift?
Assuming you are married, you and your spouse can each gift 18k of stock, so a total of 36k can be gifted. If you are in the 15% LTCG bracket, you would want at least 19167 of LTCG built up. If you are in the 20% LTCG bracket, then it would be 15000 of LTCG
How does this help?
If you were planning to cash flow college, but you have this appreciated stock in a taxable account, you could gift the stock to your student, have them sell it, and pay the college with the proceeds. You could then repurchase the same stock with the money that you were going to use to cash flow the college payment. This effectively resets your basis and removes the taxable gains from your account.
How does this work with a 529? Should I do this instead of a 529?
This can work in conjunction with a 529. For those who are worried about overfunding a 529, you can partially fund the 529 and then put some money in a taxable account as well. The amount in the 529 is used for the heavy lifting, and the money in the taxable account is used to cover whatever shortfalls are in the 529 account. The provides flexibility so that if the taxable account is overfunded, there is no penalty in using that money for some other purpose.
What about LLC?
LLC is the Lifetime Learning Credit, and very similar to the AOTC, it allows for tax credits as well. These credits are all non-refundable, they provide credit for 20% of the payments (up to 2000 max of credits), but they can be used for any level of college education. Also, while AOTC can be used for only 4 years, most students are actually in school for a total of 5 tax years. So the "back door AOTC" can also be used as a "back door LLC" strategy too for the following scenarios
- 5th tax year of an undergraduate education
- Part of master's degree
- Dual enrollment course from a student's high school
NOTE: the IRS has a few different definitions of "dependency" that will differ based on what part of the code you are looking at. In some places, a person is considered independent if the person provide over half of their own support. In other places, the dependency test requires that the person supplies over half of the support via earned income. For purposes of the "back door AOTC", neither definition matters. You aren't trying to declare your student as independent. Instead, you merely need to not list your student as a dependent.
EDITED to add how to model this in Turbo Tax
To get Turbo Tax to show the credit, do the following (all on your student's return). Also, as an aside, I was not able to get FreeTaxUSA to handle this correctly. I've reached out to their support team and they admitted that the software does not handle that (my last communication with them was in early 2023)
- In the personal section, check the box that shows that the student can be claimed as a dependent. You will then get an option, which you should select, that will then list that the student will not actually be claimed.
- List your income in the "Federal Taxes" tab in the section labelled "Child's Income (Under Age 24)". This is what will trigger the kiddie tax on unearned income
- List the investment income from the gifted capital gains in "Federal Taxes" -> "Stocks, CryptoCurrency, Mutual Funds, Bonds, Other"
- Finally, put in the 1098-T information in "Deductions & Credits" -> "Expenses and Scholarships (Form 1098-T)". After you put that in, it should ask you to run something called the "optimizer".
