Can Parents Deduct Interest Paid on a Parent PLUS Loan?
Tax season tends to raise a question families didn’t think about at borrowing time: who actually gets credit for the interest being paid on a Parent PLUS loan?
The short answer
Generally, the parent who is legally obligated to repay a Parent PLUS loan — and who actually makes the payments — may be the one eligible to claim a deduction for interest paid, up to limits set by the government. The student typically cannot claim this deduction on a Parent PLUS loan, since it isn’t their legal debt, even though the money funded their education.
Why eligibility follows the legal borrower
Tax rules around student loan interest deductions generally require that the person claiming the deduction be legally obligated on the loan and be the one who actually paid the interest. Since a Parent PLUS loan is the parent’s own debt, not the student’s, it’s generally the parent who meets that legal-obligation requirement, regardless of whether the student is the one who benefited from the education the loan financed.
What kind of benefit this generally is
This type of deduction is usually structured as an adjustment to income rather than something that requires itemizing, meaning it can generally be claimed alongside the standard deduction. That’s a meaningfully different mechanism from itemized deductions, and it’s worth understanding the difference between an above-the-line and below-the-line deduction generally, since this kind of benefit is typically the above-the-line type — it reduces the income figure used to calculate tax before other deduction choices come into play.
Why the numbers aren’t fixed here
The amount of interest that can potentially be deducted, and the income levels at which the benefit phases out, are set by the government and adjusted periodically, so they shouldn’t be treated as fixed figures. Anyone estimating the value of this deduction for a specific tax year should check current thresholds directly rather than relying on a number from a prior year or a general article, since both the cap and the phase-out range tied to adjusted gross income can shift.
Other conditions that generally apply
Beyond being the legal borrower and the one who paid, the general tax rules for this deduction typically require that the loan was used for qualified education expenses and that the borrower’s filing status and income fall within eligible ranges. A parent filing separately from a spouse, for instance, is generally not eligible to claim this deduction at all under most structures, which is a filing-status consideration worth factoring into broader household tax planning.
What to weigh
Whether this deduction meaningfully affects a household’s tax outcome depends on the interest actually paid during the year, current income-based phase-out ranges, and how the rest of the return is structured. Because these are individual, year-specific calculations, this is a case where general awareness of the rule — that eligibility follows the legal borrower — is more durable than any specific number.
The takeaway
Interest paid on a Parent PLUS loan can potentially be deductible, but the parent, as the named borrower, is generally the one in position to claim it, not the student. The mechanics of the deduction, and its limits, are set by rules that change over time, so verifying current details before filing is the more reliable approach than assuming last year’s numbers still apply.
