Start with adjusted education expenses, not the Form 1098-T headline

The American Opportunity Tax Credit and Lifetime Learning Credit begin with qualified expenses that the taxpayer actually paid during the tax year for an academic period allowed by the federal timing rules. Form 1098-T is an important starting document, but box 1 does not by itself settle the credit. Payments can cross calendar years, scholarships may be reported differently, required course materials may sit outside the school’s billing system, and refunds can reverse a prior payment. Reconcile the school account, receipts and assistance before entering the calculator.

Tax-free educational assistance reduces the expenses available for either credit. That category can include tax-free scholarships and fellowships, Pell grants, employer-provided educational assistance, veterans’ benefits and the earnings portion of a tax-free 529 plan distribution. The same tuition dollar cannot support both an education credit and tax-free treatment elsewhere. This comparison subtracts the entered assistance from each alternative expense pool because the calculator is asking, “What if this student uses AOTC?” and separately, “What if this student uses LLC?” It does not add the two results.

The AOTC expense definition is broader for course materials. Books, supplies and equipment needed for the course of study may qualify even if they are purchased from a retailer rather than from the college. The LLC generally counts those items only when fees and expenses must be paid to the eligible institution as a condition of enrollment or attendance. The separate material fields preserve that difference. Do not enter the same book in both material fields merely because the calculator compares two paths; enter it in the LLC field only if the stricter payment condition is also met.

Room and board can be a qualified 529 expense in some situations, but it is not a qualified expense for either education credit. Transportation, insurance, medical expenses and optional activity fees also do not become credit expenses simply because they are part of the cost of attending college. Keeping those categories outside this worksheet prevents the comparison from overstating both options.

Test AOTC student eligibility before valuing the $2,500 maximum

AOTC can be worth up to $2,500 per eligible student. The formula pays 100% of the first $2,000 of adjusted qualified expenses and 25% of the next $2,000. Expenses above $4,000 do not increase that student’s AOTC. Up to 40% of the allowed credit can be refundable, so the familiar maximum refundable amount is $1,000. The remaining portion is nonrefundable and needs available income tax.

The maximum is available only after passing every student-level test. At the beginning of 2025, the student must not already have completed the first four years of postsecondary education as determined by the eligible educational institution. The student must enroll at least half-time for at least one academic period beginning in the year. AOTC and the former Hope credit cannot already have been claimed for that student for four tax years. A felony drug conviction as of year-end also prevents the credit. The four visual gates in this calculator require affirmative confirmation rather than assuming a student qualifies from the amount of tuition alone.

The person claiming the student must also satisfy return-level rules. The student can be the taxpayer, the taxpayer’s spouse or a dependent claimed on the return. When a parent claims a student as a dependent, the parent generally claims the education credit even if the student paid the expenses. If the parent could claim the student but chooses not to, special rules determine whether the student can treat certain payments as their own. This is a dependency decision, not a field the calculator can infer.

Refundability has another gate. Form 8863 applies special rules to certain students under age 24, including tests involving age, earned income, support and whether a parent was living. A student may still have a nonrefundable AOTC even when the refundable portion is unavailable. Selecting “not eligible or not yet confirmed” makes this calculator conservatively treat the entire phased AOTC as nonrefundable and subject to the tax-liability entry.

Compare LLC when the student, program or year does not fit AOTC

The Lifetime Learning Credit is 20% of up to $10,000 of adjusted qualified expenses, producing a maximum of $2,000 per return. “Per return” is the crucial distinction: adding a second or third LLC student does not create another $2,000 ceiling. The calculator models one student’s expense contribution for comparison, but a return with multiple LLC students must combine all their adjusted LLC expenses under the single $10,000 return-level cap.

LLC is entirely nonrefundable. It can reduce income tax to zero, but it cannot create a refund by itself. Its flexibility lies elsewhere. There is no four-year claim limit, no half-time requirement and no requirement that the student pursue a degree. Courses taken to acquire or improve job skills may qualify when taken at an eligible educational institution. Graduate school and a single eligible course can therefore fit LLC even when AOTC is unavailable.

For 2025, both credits use the same MAGI phaseout ranges: $80,000 through $90,000 for single, head-of-household and qualifying-surviving-spouse filers, and $160,000 through $180,000 for married couples filing jointly. Married filing separately generally cannot claim either credit. Within the range, the tentative credit is reduced proportionally. The calculator uses a planning percentage; Form 8863 and tax software apply the form’s rounding instructions.

Tax liability can change the winner. Suppose an eligible undergraduate has $4,000 of adjusted AOTC expenses, qualifies for the refundable component, and the return has only $300 of tax available. AOTC can still provide a $1,000 refundable part plus $300 of its nonrefundable part, for an estimated $1,300 usable amount. LLC on the same expenses would generate only an $800 tentative nonrefundable credit and use $300. A simple comparison of “$2,500 versus $2,000” would miss the return-level reality.

Choose one credit per student and coordinate the entire return

A taxpayer cannot claim AOTC and LLC for the same student in the same year. The result highlights whichever estimated usable credit is larger, but “larger for this student” is not always the globally best choice on a multi-student return. Because LLC has one $10,000 expense ceiling for the whole return, assigning one student’s expenses to AOTC may leave room for another student’s graduate tuition under LLC. Run each student separately, then test the combined allocation before filing.

The decision also interacts with scholarships. Some scholarships can be applied to either qualified tuition or broader educational costs under their terms. In limited situations, including a scholarship amount in the student’s taxable income can free tuition for an education credit, but that choice has eligibility, dependency, kiddie-tax and scholarship-restriction consequences. Do not automatically reclassify assistance merely because the calculator shows a larger credit. The scholarship’s terms and the student’s complete return must support the allocation.

Form 1098-T is generally required, subject to specific exceptions. Confirm that the institution is eligible, that the taxpayer identification number is correct and that claimed expenses match the academic period rules. Payments made in 2025 for an academic period beginning in the first three months of 2026 can qualify under the prepayment rule. A later refund of qualified expenses can require recapture, so preserve account statements after filing.

A clean workpaper should show each student’s institution, academic periods, enrollment level, first-four-year status, prior AOTC claim years, tuition payments, required materials, refunds and each source of tax-free assistance. Attach the chosen allocation to the return file. That record explains why a Form 1098-T amount changed, why a 529 distribution did not use the same tuition, and why the selected credit was allowed.
