What 529 Plans Actually Cover (and What They Don't)

529 education savings plans have rules that catch many families off guard. This reference explains qualified expenses, penalties, and key limitations.

What is a 529 plan?

A 529 plan is a tax-advantaged savings account designed specifically for education costs. Contributions grow free of federal income tax, and withdrawals are also tax-free when used for qualified expenses. Most states offer their own 529 programs, and many provide a state income tax deduction for contributions.

Two types exist: college savings plans, which function like investment accounts, and prepaid tuition plans, which lock in tuition credits at participating public colleges. This article focuses primarily on college savings plans, which are more widely used.

For a broader overview of how 529s fit into a family's financial picture, see the 529 plans explained guide from our finance section.

Federal tax treatment	Earnings grow tax-free; qualified withdrawals are tax-free (IRS Publication 970)
K-12 annual limit	$10,000 per beneficiary per year (Tax Cuts and Jobs Act of 2017)
Student loan repayment cap	$10,000 lifetime per beneficiary (SECURE Act, 2019)
Roth IRA rollover lifetime cap	$35,000 per beneficiary (SECURE 2.0 Act, 2022)
Penalty on non-qualified earnings	10% federal penalty plus income tax (IRS Section 529)
FAFSA asset assessment rate (parent-owned)	Up to 5.64% of account value (Federal Student Aid formula)

Qualified expenses: what 529 funds can pay for

The IRS defines "qualified higher education expenses" for federal tax purposes. Withdrawals used for these expenses are tax-free at the federal level.

Tuition and mandatory fees at accredited colleges, universities, and vocational schools
Room and board, up to the school's published cost-of-attendance allowance, for students enrolled at least half-time
Books, supplies, and equipment required for enrollment (not optional purchases)
Computers, software, and internet access if used primarily for school
Special needs services for students with disabilities
Apprenticeship programs registered with the U.S. Department of Labor
Student loan repayments, up to a lifetime limit of $10,000 per beneficiary and $10,000 per sibling

K-12 tuition at public, private, or religious elementary and secondary schools qualifies for up to $10,000 per year per beneficiary under federal rules, though state tax treatment varies.

The SECURE 2.0 Act, signed into law in December 2022, added a new provision: starting in 2024, unused 529 funds can be rolled into a Roth IRA for the beneficiary, subject to annual IRA contribution limits and a $35,000 lifetime cap, provided the account has been open at least 15 years.

What 529 funds cannot pay for

This is where many families run into trouble. Withdrawals used for non-qualified expenses are subject to federal income tax plus a 10% penalty on the earnings portion of the withdrawal.

Common expenses that do not qualify include:

Transportation and travel to and from school (airfare, gas, parking passes)
Health insurance premiums or medical costs
College application or testing fees (SAT, ACT, AP exam fees)
Extracurricular activity fees, gym memberships, or sports equipment
Room and board above the school's official cost-of-attendance figure
Repaying federal student loans above the $10,000 lifetime limit
Expenses at non-accredited institutions

State tax rules may differ from federal rules

Federal law sets the floor for 529 qualified expenses, but states are not required to follow every federal change. Some states have not conformed to the K-12 tuition provision or the student loan repayment rule, meaning a withdrawal that is penalty-free federally could still trigger state taxes or recapture of a prior deduction. Check with your state's 529 plan administrator or a tax professional before making withdrawals that rely on these provisions.

If a student receives a scholarship, you can withdraw an equivalent amount from the 529 without the 10% penalty, though income tax still applies to the earnings portion. This is known as the scholarship exception.

How 529 assets affect financial aid

529 plan assets owned by a parent are reported on the FAFSA (Free Application for Federal Student Aid) at a maximum rate of 5.64% in the federal financial aid formula. That means a $20,000 balance would reduce a student's Expected Family Contribution by at most about $1,128. Assets owned by a grandparent or other relative were historically treated differently, but FAFSA simplification changes that took effect for the 2024-25 aid year removed the question about student cash support, which had previously counted as student income and had a heavier impact.

For more detail on how savings and other factors shape a financial aid package, the FAFSA guide explains the formula in plain terms.

Changing the beneficiary and transferring funds

If the original beneficiary does not use all the funds, the account owner can change the beneficiary to any member of the family, including siblings, cousins, parents, or spouses, without triggering taxes or penalties. The IRS defines "family member" broadly for this purpose.

The 2024 Roth IRA rollover option described above adds another exit path, though the 15-year account age requirement and annual IRA contribution limit mean it works best as a long-range contingency rather than an immediate solution.

Families who overfund a 529 or whose child earns a full scholarship have options. A non-qualified withdrawal is not necessarily a catastrophe: only the earnings portion faces tax and the 10% penalty, not the original contributions.
