The tax code provides several overlapping education incentives - but they cannot be stacked on the same dollars. The coordination rules require choosing which benefit applies to each dollar of qualified expenses, and the wrong choice can eliminate a credit or create a taxable distribution. Understanding which benefit is most valuable, and which expenses qualify for which benefit, is essential for families paying for higher education.
AOTC: Up to $2,500 credit (100% of first $2,000 + 25% of next $2,000); 40% refundable; phaseout $80,000-$90,000 (single) / $160,000-$180,000 (MFJ)
LLC: Up to $2,000 credit (20% of up to $10,000 qualified expenses); nonrefundable; phaseout $80,000-$90,000 (single) / $160,000-$180,000 (MFJ)
§529 K-12: Up to $10,000 per year per beneficiary for K-12 tuition
Student loan interest deduction: Up to $2,500 above-the-line; phaseout $75,000-$90,000 (single) / $155,000-$185,000 (MFJ) - OBBBA restored full deductibility for most
The AOTC is the most valuable education tax credit. It provides a credit of 100% of the first $2,000 of qualified education expenses plus 25% of the next $2,000 - a maximum of $2,500 per eligible student per year. Forty percent of the credit ($1,000 maximum) is refundable, meaning it can produce a refund even when no tax is owed.
Qualified expenses for the AOTC include tuition, fees, and course materials (books, supplies, and equipment) required for enrollment. Room and board do not qualify.
The LLC provides a credit of 20% of up to $10,000 of qualified tuition and fees - a maximum $2,000 credit per return (not per student). Unlike the AOTC, the LLC is nonrefundable. The LLC has no limit on the number of years it can be claimed and does not require the student to pursue a degree - continuing professional education and courses to acquire or improve job skills qualify.
Only one credit can be claimed per student per year - a taxpayer cannot claim both the AOTC and the LLC for the same student in the same year. When a student qualifies for the AOTC, it is almost always the better choice because of the higher maximum and the refundable component.
A §529 plan is a state-sponsored savings account for qualified education expenses. Contributions are not federally deductible (though many states provide a state income tax deduction). Earnings grow tax-free and qualified distributions are excluded from income. Contribution limits are set by the states and are generally very high (often $500,000+ per beneficiary over the life of the account).
Distributions are tax-free when used for qualified education expenses. For higher education: tuition, fees, books, supplies, equipment, room and board (if enrolled at least half-time), and special needs services. For K-12: up to $10,000 per year per beneficiary for tuition at an elementary or secondary school (public, private, or religious). SECURE 2.0 expanded qualified expenses to include apprenticeship programs and up to $10,000 of student loan repayments (lifetime limit per beneficiary).
Distributions not used for qualified education expenses are includable in income (the earnings portion only) plus a 10% additional tax on the earnings. If the beneficiary receives a scholarship, the 10% penalty is waived on distributions up to the scholarship amount - but the income tax still applies.
A §529 account can be rolled over tax-free to another §529 account for the same beneficiary or a member of the beneficiary's family (sibling, parent, cousin, etc.). SECURE 2.0 allowed rollovers to a Roth IRA for the beneficiary, subject to limits: the §529 must have been open for 15+ years, annual rollovers are limited to the IRA contribution limit ($7,000 for 2026), and the lifetime rollover limit is $35,000.
This is the most important planning point. The same dollar of qualified education expenses cannot produce both a tax credit (AOTC or LLC) and a tax-free §529 distribution. If $10,000 is paid from a §529 plan and the full $10,000 is used to claim the AOTC (using $4,000 for the credit and $6,000 tax-free from §529), the $4,000 used for the AOTC cannot also be covered by the §529 tax-free.
Up to $2,500 of interest paid on qualified student loans is deductible above-the-line under IRC §221. The deduction phases out between $75,000-$90,000 (single) and $155,000-$185,000 (MFJ) of MAGI. The loan must have been taken out solely to pay qualified education expenses for the taxpayer, spouse, or dependent. Interest on loans from related parties does not qualify.
