Can You Use 529 Funds to Pay Student Loans? $10K Cap and Rules

You can use 529 funds to pay student loans, up to a $10,000 lifetime cap per borrower, thanks to a change made by the SECURE Act of 2019. Withdrawals within that cap are treated as qualified higher education expenses, so they escape both federal income tax and the 10% penalty that normally applies to non-education distributions.¹

The $10,000 Lifetime Cap

Each borrower can receive a maximum of $10,000 in 529 distributions applied to their student loans over their entire lifetime.² The cap follows the borrower, not the account. If two different 529 plans each send $6,000 toward the same person’s loans, $2,000 of that total is over the limit.

Anything above $10,000 becomes a non-qualified withdrawal. The earnings portion of the excess gets hit with ordinary federal income tax plus the 10% penalty.¹ The contribution portion is not taxed again, since it went in with after-tax dollars in the first place.

The cap is per borrower, so a family with three children has three separate $10,000 buckets available across their respective loans.

Whose Loans You Can Pay

Two people qualify: the 529’s designated beneficiary, and any sibling of the beneficiary. Siblings include brothers, sisters, stepbrothers, stepsisters, and half-siblings.¹³

To pay a sibling’s loans, you can either request a distribution directly for those loans or change the account’s beneficiary to the sibling first. Beneficiary changes among family members do not trigger taxes or penalties.¹

Parent PLUS Loans

Parent PLUS loans belong legally to the parent, not the student. Because the 529 rule covers only loans of the beneficiary or a sibling, a Parent PLUS loan does not qualify while the child is the account’s beneficiary.¹ There is a workaround: parents count as family members, so you can change the beneficiary to the parent who holds the PLUS loan without any tax hit. Once the parent is the named beneficiary, their PLUS loan qualifies, subject to its own $10,000 lifetime cap.

Which Loans Qualify

The provision uses the tax code’s existing definition of a “qualified education loan”: debt taken out solely to pay for higher education costs like tuition, room and board, books, and fees.⁴ Federal loans (Direct Subsidized, Direct Unsubsidized, Grad PLUS) and private student loans both qualify, as long as the original purpose was qualified education expenses.

Refinanced and consolidated loans also qualify. The statute explicitly includes “indebtedness used to refinance indebtedness which qualifies as a qualified education loan.”⁴ If you refinanced federal loans into a private loan or bundled several loans together, the new loan still counts. Loans from related parties, such as money borrowed from a family member, are excluded.

Watch the Interaction With the Student Loan Interest Deduction

Taxpayers can normally deduct up to $2,500 a year in student loan interest paid.⁴ Interest paid with a tax-free 529 distribution cannot also be deducted; the IRS does not let you claim two tax benefits on the same dollars.⁵

Say you pay $3,000 in student loan interest during the year, and $1,200 of that came from a 529 distribution. You subtract the $1,200 first, leaving $1,800 of interest that stays deductible if your income falls within the allowed range. If the 529 covered the whole interest payment, you get no deduction at all that year.

For 2026, the student loan interest deduction phases out between $85,000 and $100,000 in modified adjusted gross income for single filers, and between $175,000 and $205,000 for joint filers.⁶ Above the top of those ranges the deduction disappears, and this interaction stops mattering.

State Tax Treatment May Differ

The federal rules are only half the picture. Each state decides on its own whether to treat student loan repayment as a qualified 529 expense, and not every state has conformed. In a non-conforming state, the distribution can be treated as non-qualified for state purposes even when it is fine federally.

Two things can happen as a result. If you previously took a state income tax deduction for your 529 contributions, the state may recapture that deduction and add it back to your taxable income for the year of the withdrawal. And the earnings portion of the distribution can be subject to state income tax. Check with your state tax agency or your 529 plan administrator before requesting a loan-payment distribution.

How to Request the Distribution

To send 529 money toward a student loan, you will generally need your loan servicer’s name, mailing address, and your loan account number. Most plan providers also ask for the servicer’s taxpayer identification number so the payment routes correctly.

Providers typically offer three payment methods:

Electronic transfer directly from the 529 to your bank account or the servicer, usually within one to three business days.
A physical check mailed to the loan servicer, which can take up to ten business days.
A check mailed to you, which you then forward to the servicer. Slower, but you control when the payment posts.

Your provider will send Form 1099-Q for the year, reporting the total distribution and the split between contributions and earnings.⁵ Keep your own records showing that the money went to student loan repayment and that the running total for that borrower has not passed $10,000. There is no dedicated IRS form for reporting 529 loan payments, so your paperwork is what protects you in an audit.

Try to take the withdrawal in the same calendar year the loan payment is applied. Matching the two avoids timing mismatches between the 1099-Q and the expense it is meant to cover.

If You Have More Than $10,000 Left Over

Once you have hit the $10,000 loan-repayment cap for a beneficiary, the SECURE 2.0 Act of 2022 opened another door: rolling unused 529 funds into a Roth IRA for the beneficiary.⁷ Several conditions apply. The 529 must have been open more than 15 years. Contributions and their earnings from the past five years cannot be rolled. The yearly rollover counts against the beneficiary’s Roth IRA contribution limit, which is $7,500 for 2026.⁸ The lifetime cap for 529-to-Roth rollovers is $35,000 per beneficiary. And the beneficiary must have earned income at least equal to the rollover amount that year. The transfer has to move trustee-to-trustee into a Roth IRA held for the beneficiary, not the account owner.
