1098-T Box 4: Prior Year Adjustments, Recapture, and Reporting

A dollar figure in Box 4 of Form 1098-T is a prior year adjustment: your school is reporting that tuition or related expenses it told the IRS about in an earlier year have since been refunded or reduced. The Box 4 amount does not change this year’s education credit. It looks backward, and if it lowers the qualified expenses that supported an American Opportunity or Lifetime Learning Credit you already claimed, you owe the difference back as additional tax on your current year’s return.¹

What Box 4 Means

Box 4 is labeled “Adjustments made for a prior year.” The number there represents amounts previously reported in Box 1 of an earlier 1098-T that have been refunded or reduced. The adjustment appears on the current form because the refund or reduction happened in the current calendar year, even though the original expense belonged to a different tax year.¹

This is the mechanism the IRS calls recapture. If the lower expense figure means you were entitled to a smaller credit than you took, you repay the difference. You do not amend the old return; the fix happens on this year’s.²

When It Costs You Money and When It Doesn’t

Not every Box 4 figure creates a tax bill. You owe nothing extra if any of these is true:

You didn’t claim an education credit for the year the adjustment relates to. No credit, nothing to recapture.
Your corrected expenses still support the full credit you took. The AOTC maxes out at $4,000 in expenses, so if you had $6,000 originally and Box 4 shows a $1,500 reduction, your $4,500 of corrected expenses still produces the full $2,500 credit.
Your income phase-out had already reduced your credit below what the lower expense figure would produce.

Box 4 only costs you money when the reduction drops your corrected expenses below the level that justified the credit you actually received. If you’re in one of the three situations above, you can stop here.

How to Calculate What You Owe

The Box 4 amount is not what you owe. It’s the input to a recalculation.²

Pull Your Prior Year Return

Find the Form 8863 you filed for the year the adjustment relates to. You need two things from it: the qualified education expenses you used, and which credit you claimed. The AOTC and the Lifetime Learning Credit use different formulas, so the math only works if you know which one you took.

Subtract and Recalculate

Subtract the Box 4 amount from the qualified expenses you originally reported. Then run the credit formula again on the lower figure, using the eligibility and income rules that applied in the prior year, not the current one.

American Opportunity Tax Credit: 100% of the first $2,000 in expenses plus 25% of the next $2,000, for a maximum of $2,500. Forty percent (up to $1,000) is refundable.³
Lifetime Learning Credit: 20% of the first $10,000 in expenses, for a maximum of $2,000 per return.⁴

Subtract the recalculated credit from the credit you originally claimed. That difference is your recapture amount.

A Worked Example

Publication 970 uses this illustration. You paid $7,000 in tuition in 2025 and claimed a $2,500 AOTC on your 2025 return. After filing, you received a $4,000 refund. Your corrected expenses drop to $3,000. The AOTC on $3,000 is $2,000 (100% of the first $2,000) plus $250 (25% of the next $1,000), for a total of $2,250. The difference between the $2,500 you took and the $2,250 you should have taken is $250. That $250 is the additional tax on your 2026 return.²

How to Report It on This Year’s Return

You do not amend the old return. The IRS instruction is to “include that amount as an additional tax for the year the refund or tax-free assistance was received.”²

The recapture goes on Schedule 2 (Additional Taxes), which accompanies Form 1040. The current year’s Form 1040 instructions identify the specific Schedule 2 line for education credit recapture, and the Schedule 2 total flows to your 1040 and increases your tax for the year.⁵

Keep the paperwork that backs up the number: the original Form 8863 from the prior year, the current 1098-T showing Box 4, and your recalculation. Tax software handles the arithmetic if you enter the Box 4 amount, but it can only work with what you give it.

Why Box 4 Appeared on Your Form

Almost every Box 4 entry comes from a timing mismatch. The expense was reported in one calendar year, and the event that reduced it happened in the next.

A Withdrawal After Year-End

You pay fall tuition in Year 1 and the school reports it on the Year 1 1098-T. You withdraw in early Year 2 within the school’s refund window. The refund arrives in Year 2 and the school reports the refunded amount in Box 4 of the Year 2 form.

A Retroactive Scholarship or Grant

A scholarship awarded in January of Year 2 covers the previous fall semester in Year 1. Scholarships reduce qualified expenses, so the retroactive award lowers the expenses that supported the Year 1 credit.⁶ The school reports the impact in Box 4 of the Year 2 form.

A Billing Correction

Sometimes a school discovers it overstated tuition for an earlier year. The correction appears in Box 4 and, for tax purposes, works the same as a refund.

If Box 6 Also Appears

Box 6 is the mirror of Box 4: it reports reductions to prior-year scholarships or grants that were originally reported in Box 5.¹ Because scholarships offset qualified expenses, a scholarship reduction effectively increases the prior year’s qualified expenses and may entitle you to a larger credit for that year. The fix in that direction does require an amended return (Form 1040-X) for the affected year.

What Happens If You Skip It

An unreported recapture is an underpayment of tax, and the IRS has the same 1098-T your school filed, which makes this an easy item to match against your return.

Interest runs on the unpaid tax from the original due date until you pay. The individual underpayment rate for the first quarter of 2026 is 7% per year, compounded daily.⁷
An accuracy-related penalty of 20% of the underpayment applies if the IRS finds negligence or a substantial understatement. For individuals, substantial means an understatement of 10% of the correct tax or $5,000, whichever is greater.⁸
For the AOTC, the IRS warns that incorrect claims can result in a ban from the credit for 2 to 10 years, in addition to repayment with interest and possible fraud penalties.³
