AOTC Calculator: American Opportunity Tax Credit

The American Opportunity Tax Credit (AOTC) is worth up to $2,500 per eligible student a year: 100% of the first $2,000 of qualified expenses plus 25% of the next $2,000. 40% of the credit you are allowed is refundable (up to $1,000 per student), and the credit phases out between $80,000 and $90,000 of modified AGI ($160,000–$180,000 joint). Enter each student below to see the split between the refundable and nonrefundable parts.

This calculator is for informational purposes only. The result is an estimate built from the numbers you enter; your actual credit is figured on Form 8863 when you file.

How the AOTC is calculated

The calculator follows Form 8863 in the same order the IRS does.

1. Credit per student (Part III, line 30). 100% of the first $2,000 of adjusted qualified expenses plus 25% of the next $2,000. Anything above $4,000 adds nothing.
2. Add the students (line 1). Only students who pass every eligibility test count.
3. Phase-out (lines 2–7). If MAGI is above $80,000 ($160,000 joint), multiply the total by the share of the phase-out range you have not used: ($90,000 − MAGI) ÷ $10,000, or ($180,000 − MAGI) ÷ $20,000 joint.
4. Refundable part (line 8). 40% of the line 7 amount. This is the step many estimates get wrong: the 40% applies to the whole allowed credit, not to whatever is left after your tax is wiped out.
5. Nonrefundable part (line 9). The other 60%, which can only reduce your tax to zero on the Credit Limit Worksheet. Any unused amount is lost; it does not carry forward.

The statute behind steps 3 and 4 is IRC §25A: subsection (d) sets the $80,000/$160,000 thresholds with a $10,000/$20,000 range, and subsection (i) makes 40% refundable. Neither figure is indexed for inflation, which is why the calculator gives the same answer for 2025 and 2026.

How much of the credit you actually get

For one student with $4,000 or more of expenses and MAGI below the phase-out, the $2,500 credit splits into $1,000 refundable and $1,500 nonrefundable. Your tax bill decides how much of the $1,500 you can use:

If other nonrefundable credits, such as the child tax credit, already use up part of your tax, enter only the tax that is left as your "tax liability before credits."

Who is an eligible student?

Form 8863 instructions list seven requirements. The student must:

1. Not have completed the first four years of postsecondary education before the start of the year, as determined by the school.
2. Not have had the AOTC (or the old Hope credit) claimed for any four earlier tax years, by anyone.
3. Be enrolled in a program leading to a degree, certificate or other recognized credential, carrying at least half the normal full-time workload for at least one academic period that starts in the year. Full-time students obviously meet this.
4. Have no federal or state felony drug conviction as of the end of the year.
5. Have the required taxpayer identification number by the return due date (see the 2026 change below).
6. Have received Form 1098-T, unless one of the exceptions applies (for example, the school was not required to send one, or you asked for it after January 31 and the school still did not furnish it).
7. Attend a school whose employer identification number (EIN) you enter on Form 8863.

In the calculator, a student who has used four AOTC years or is enrolled less than half-time gets $0, and the reason is shown under that student. A fifth-year undergraduate who has already completed four years of study fails test 1 even if the AOTC was claimed only three times; use the Lifetime Learning Credit calculator for that student.

Who can claim the credit

• Married filing separately: no credit. Married couples must file jointly to claim any education credit.
• MAGI at or above $90,000 ($180,000 joint): no credit. MAGI is Form 1040 line 11 plus any excluded foreign or Puerto Rico income; the MAGI calculator shows the add-backs.
• Dependents. If a student is claimed as a dependent, only the person claiming them can take the credit, and expenses the student or a relative paid are treated as paid by that person. If nobody claims the student, only the student can.
• 2026 identification rule. For tax years beginning after 2025, the law (as amended by the One Big Beautiful Bill Act) requires the claimant's Social Security number and the student's Social Security number; an ITIN no longer works. For 2025, an ITIN issued by the due date was still acceptable. The calculator's checklist changes with the tax year you pick.

The under-24 rule

The refundable part is not available if, at the end of the year, you were under 18, or 18 with earned income below half your support, or a full-time student aged 19 to 23 with earned income below half your support — and at least one parent was alive and you are not filing jointly (Form 8863, line 7). Students who file their own return usually fall into this group. Tick the box in the calculator and the whole credit becomes nonrefundable.

What counts as a qualified expense

• Tuition and required fees paid to the school.
• Course materials — books, supplies and equipment needed for a course — even if you buy them somewhere other than the school. This is broader than the Lifetime Learning Credit, which counts materials only when they must be paid to the school.
• Not included: room and board, insurance, student health fees, transportation, and other personal expenses, even when the school bills them.

Reduce expenses by tax-free help used for them: the tax-free part of scholarships and Pell grants, tax-free employer education assistance, and veterans' benefits. You also cannot use the same dollars for a tax-free 529 or Coverdell withdrawal. A common plan is to pay at least $4,000 of tuition from income or loans and use the 529 for housing; the 529 vs. UTMA calculator covers how 529 money is treated.

Expenses count in the year you pay them, for academic periods starting that year or in the first three months of the next. Tuition paid in December 2026 for a semester starting in January 2027 belongs on the 2026 return.

Worked examples

Freshman, parents with enough tax

Married couple, MAGI $120,000, tax before credits $3,500. Tuition and fees $11,000, required books $800.

• Expenses over $4,000, so the credit is $2,000 + $500 = $2,500
• No phase-out (MAGI under $160,000)
• Refundable: 40% × $2,500 = $1,000
• Nonrefundable: $1,500, fully used; tax drops from $3,500 to $2,000
• Total benefit: $2,500, of which $1,000 arrives as part of the refund

Low tax bill

Married couple, MAGI $35,000, tax before credits $800. Community college tuition $4,500, books $600.

• Credit: $2,500; refundable $1,000
• Nonrefundable $1,500, but only $800 of tax to absorb it
• Total benefit: $800 + $1,000 = $1,800; $700 is lost

Under the old shortcut of "use the credit against tax first, then refund 40% of the rest," this family would have been told $800 + 40% × $1,700 = $1,480 — $320 too little.

Two students in the phase-out

Married couple, MAGI $170,000, tax before credits $9,000. Two eligible students with $8,000 and $6,000 of expenses.

• Before phase-out: $2,500 × 2 = $5,000
• Phase-out share kept: ($180,000 − $170,000) ÷ $20,000 = 50%
• Allowed credit: $2,500
• Refundable: $1,000; nonrefundable $1,500, fully used

Lowering MAGI to $160,000 — for example with $10,000 more of pre-tax 401(k) deferrals — would restore the full $5,000.

Student filing alone under the under-24 rule

A 20-year-old full-time student, not claimed by her parents, earns $18,000 while her total support (tuition, housing, food) is about $40,000, so her earned income is under half her support. Her 2026 tax before credits is $190 ($18,000 − $16,100 standard deduction = $1,900 at 10%); tuition is $6,000.

• Credit: $2,500, but the under-24 rule applies, so nothing is refundable
• Benefit: $190, the amount of her tax

If her parents can claim her (and are under the phase-out), they would usually get the full $2,500 instead.

Reading the results panel

• Total AOTC benefit is the refundable part plus the nonrefundable part your tax can absorb.
• Credit after phase-out is Form 8863 line 7 — the allowed credit before the tax limit.
• Nonrefundable credit lost appears when your tax is smaller than 60% of the allowed credit.
• Per-student breakdown shows each student's credit before and after the phase-out and why an ineligible student gets $0.
• Multi-year planning counts the AOTC years left for each student out of four.

Mistakes that cost families money

1. Claiming a fifth year. Four tax years per student, and only while the first four years of study are unfinished.
2. Leaving out books bought elsewhere. Required course materials count for the AOTC even when bought online.
3. Double-dipping with a 529. Expenses used for the credit must come out of the 529's qualified-expense total.
4. Ignoring scholarships. Tax-free scholarships reduce expenses. Sometimes treating part of a scholarship as taxable income frees up $4,000 of expenses for the credit; Pub. 970 shows how.
5. Filing separately. A married couple filing separate returns cannot claim it at all.
6. Improper claims. If a claim is found reckless, you cannot claim the AOTC for 2 years (10 years for fraud), and after any disallowance you must attach Form 8862 the next time.
