Who it applies to
Taxpayers who paid interest on qualified education loans and are claiming the student loan interest deduction on their 2020 federal income tax return.
What changed this year, and why
For tax year 2020, the IRS published the income thresholds at which the student loan interest deduction phases out. The maximum deduction remains $2,500. Single filers begin to lose the deduction when their modified adjusted gross income exceeds $70,000, and it is fully phased out at $85,000 or more. For joint filers, the phase-out begins above $140,000 and is complete at $170,000 or more.
Common questions
- What is the Student Loan Interest Deduction and how does it work?
- The Student Loan Interest Deduction lets eligible taxpayers subtract from their income the interest they paid on qualified education loans during the year, up to a maximum amount. For 2020, the maximum deduction is $2,500. The deduction phases out for single filers with modified adjusted gross income between $70,000 and $85,000, and for joint filers with income between $140,000 and $170,000.
How the deduction is reduced inside the phase-out range
When a taxpayer's modified adjusted gross income falls between the phase-out threshold and the fully phased-out level, the deduction is reduced by a specific fraction rather than eliminated entirely. The formula requires multiplying the interest deduction (before any phase-out, but capped at $2,500) by a fraction. The numerator of that fraction is the taxpayer's MAGI minus $70,000 for a single filer, or minus $140,000 for a joint return. The denominator is $15,000 for a single filer, or $30,000 for a joint return. That product is then subtracted from the original deduction (before the phase-out) to determine the amount the taxpayer can actually deduct. As income rises across this range the fraction grows from zero toward one, and the remaining deduction shrinks correspondingly. The width of the range is $15,000 for single filers and $30,000 for joint filers. Once MAGI reaches the fully phased-out amount, the fraction equals one and the entire deduction is lost.
To figure the phaseout, multiply your interest deduction (before the phaseout, but not more than $2,500) by a fraction. The numerator (top part) is your MAGI minus $70,000 ($140,000 in the case of a joint re- turn). The denominator (bottom part) is $15,000 ($30,000 in the case of a joint return). Subtract the result from your deduction (before the phaseout) to give you the amount you can deduct.

The income the phase-out is measured on
The student loan interest deduction is an adjustment to income, meaning you can claim it even if you don't itemize deductions. However, eligibility depends on your modified adjusted gross income. For most taxpayers, MAGI is the adjusted gross income as figured on their federal income tax return before subtracting any deduction for student loan interest. This means your MAGI is calculated before reducing it by the student loan interest deduction itself. The deduction is available if your MAGI is less than $85,000 for single filers or less than $170,000 for joint filers. Within the phase-out range ($70,000 to $85,000 for single; $140,000 to $170,000 for joint), the deduction is reduced proportionally. The maximum deduction is $2,500, which can reduce your taxable income by that amount if your MAGI falls below the phase-out threshold.
For most taxpayers, MAGI is the adjus- ted gross income as figured on their federal income tax re- turn before subtracting any deduction for student loan in- terest.

Who can claim the deduction
To claim the student loan interest deduction, you must meet all four of the following requirements. First, your filing status cannot be married filing separately - all other filing statuses qualify. Second, no one else can claim you as a dependent on their tax return. Third, you must be legally obligated to pay interest on a qualified student loan under the loan terms. Fourth, you must have actually paid interest on a qualified student loan during the tax year. If any of these conditions is not satisfied, you cannot claim the deduction regardless of how much interest you paid or how low your income may be. The deduction is claimed as an adjustment to income on your tax return, so you do not need to itemize deductions to benefit from it.
Generally, you can claim the deduction if all of the follow- ing requirements are met.

Payments that do not count as student loan interest
You can't claim a student loan interest deduction for any of the following items. Interest you paid on a loan is not deductible if, under the terms of the loan, you are not legally obligated to make interest payments. Loan origination fees are not deductible to the extent they are payments for property or services provided by the lender, such as commitment fees or processing costs. Interest you paid on a loan is also not deductible to the extent payments were made through your participation in the National Health Service Corps Loan Repayment Program or certain other loan repayment assistance programs. In each case, the payment fails to qualify as student loan interest for purposes of the deduction. Only interest you are legally obligated to pay, and that you actually pay from your own funds, counts toward the $2,500 maximum deduction.
You can't claim a student loan interest deduction for any of the following items.
