How Do the Two Education Credits Differ?
The American Opportunity Tax Credit (AOTC) is worth up to $2,500 per eligible student and is limited to the first four years of postsecondary education, while the Lifetime Learning Credit (LLC) is worth up to $2,000 per tax return and has no limit on the number of years it can be claimed. The AOTC is partially refundable, paying up to 40 percent as a refund even when no tax is owed, while the LLC is nonrefundable and only offsets tax liability, according to the Internal Revenue Service. A taxpayer cannot claim both credits for the same student in the same year, which makes the choice between them an annual decision.
How Is Each Credit Calculated?
- AOTC: 100 percent of the first $2,000 of qualified expenses plus 25 percent of the next $2,000, for a maximum of $2,500 per student. Up to $1,000 of that amount, 40 percent, is refundable.
- LLC: 20 percent of the first $10,000 of qualified expenses paid for all eligible students on the return, for a maximum of $2,000 per return, as described on the IRS Lifetime Learning Credit page.
The per-student versus per-return distinction matters for larger households: a family with two undergraduates can claim two AOTCs, up to $5,000 combined, while the LLC is capped at $2,000 in total no matter how many students the return covers.
Who Is Eligible for Each Credit?
The AOTC carries stricter student-level requirements. The student is pursuing a degree or credential, is enrolled at least half-time for at least one academic period, has not completed the first four years of higher education, has not had the AOTC claimed for four prior years, and has no felony drug conviction. The LLC drops nearly all of those tests: there is no enrollment intensity requirement, no year limit, no degree requirement, and no drug conviction bar. LLC-eligible coursework includes undergraduate, graduate, and professional degree courses, along with courses taken to acquire or improve job skills. Both credits share the same income phaseout, with the benefit phasing out as modified adjusted gross income runs from $80,000 to $90,000 for single filers and from $160,000 to $180,000 for joint filers.
Which Expenses Count for Each Credit?
Both credits cover tuition and enrollment fees required for attendance, but they diverge on course materials:
- AOTC: Books, supplies, and equipment needed for a course count whether or not they are purchased from the institution. A textbook bought from an outside retailer qualifies.
- LLC: Books, supplies, and equipment count only when they are paid to the institution as a condition of enrollment or attendance.
Neither credit covers room and board, transportation, or insurance, and neither can be claimed on expenses paid with tax-free money such as scholarships, Pell Grants, employer educational assistance, or tax-free 529 withdrawals. Expenses paid with loan proceeds do count, because borrowed money is not tax-free assistance, and the credit arrives years before the loan is repaid.
Which Students Typically Match Each Credit?
The eligibility rules sort students fairly cleanly. Traditional undergraduates in their first four years, enrolled at least half-time, meet the AOTC tests, and the larger, partially refundable credit produces a bigger benefit at every expense level. The LLC serves the students the AOTC excludes:
- Graduate and professional students, who are past the four-year undergraduate window.
- Undergraduates enrolled less than half-time.
- Fifth-year and returning students who have already claimed the AOTC four times.
- Working adults taking individual courses to build job skills without pursuing a degree.
- Students who completed a bachelor's degree and are taking additional coursework.
How Are the Credits Claimed?
Both credits are claimed on Form 8863, filed with the federal return. The educational institution issues Form 1098-T reporting payments received for qualified tuition and related expenses, and the form's figures feed the credit calculation. A single Form 8863 can combine credits across students, for example an AOTC for an undergraduate dependent and an LLC for a parent's graduate coursework on the same return, since the one-credit-per-student rule applies per student, not per household.
Frequently Asked Questions About the LLC and AOTC
Can a taxpayer claim both credits in the same year?
Yes, but not for the same student. A return can include an AOTC for one student and an LLC for a different student in the same tax year.
Which credit applies to graduate school?
Only the Lifetime Learning Credit. The AOTC is limited to students who have not completed the first four years of postsecondary education.
Is either credit refundable?
Only the AOTC. Up to 40 percent of it, a maximum of $1,000, is refundable. The LLC can reduce tax owed to zero but does not generate a refund beyond that.
Do the credits share income limits?
Yes. Both phase out between $80,000 and $90,000 of modified adjusted gross income for single filers and between $160,000 and $180,000 for joint filers, and neither is available above the upper limit of that range.
