Withdrawals from a California ScholarShare 529 plan are free from federal and California income tax when the money pays for qualified higher education expenses. The catch is that California hasn’t adopted every federal expansion of what “qualified” means, so certain withdrawals that are tax-free on your federal return still owe California income tax plus a 2.5% additional state tax on the earnings portion. Understanding where the state breaks from federal rules is the single most important thing to know before you request a distribution.
What Counts as a Qualified Expense
At the federal level, qualified higher education expenses include tuition, mandatory enrollment fees, books, supplies, and equipment required for coursework at an eligible postsecondary institution or vocational program.1Office of the Law Revision Counsel. 26 USC 529 – Qualified Tuition Programs Required computers, specialized lab gear, and special-needs services tied to enrollment are covered.
Room and board qualify only when the student is enrolled at least half-time in a degree or certificate program. The amount you can withdraw tax-free is capped at the greater of the school’s published cost-of-attendance allowance for room and board, or the actual amount charged for housing the school owns or operates.2Internal Revenue Service. Publication 970 (2025), Tax Benefits for Education For off-campus students, the school’s published allowance sets the ceiling.
California treats withdrawals for registered apprenticeship program expenses as qualified, matching federal treatment.3ScholarShare 529. How Our 529 Works For traditional postsecondary expenses like tuition, fees, books, and room and board, California fully conforms with federal law, and the earnings on those withdrawals are not taxed by the state.
Where California Diverges From Federal Rules
California’s tax code conforms to federal 529 rules only as of a fixed date, and the legislature hasn’t adopted every expansion Congress has added since. The result: several categories of withdrawal that are tax-free on your federal return count as non-qualified distributions in California, triggering state income tax and a 2.5% additional California tax on the earnings portion.
K-12 Tuition
Congress added K-12 tuition as a qualified 529 expense in 2018, but California has not conformed. If you use ScholarShare funds to pay elementary or secondary school tuition, the earnings portion is subject to California income tax plus the 2.5% additional state tax.3ScholarShare 529. How Our 529 Works The federal $10,000 annual cap still applies for federal purposes, but California taxes the earnings regardless of amount.
Student Loan Repayment
The federal $10,000 lifetime limit for using 529 funds to repay student loans (including sibling loans) was added in 2019, after California’s conformity date. Based on California’s general conformity framework and the pattern with other post-2017 provisions, withdrawals used for student loan repayment are likely treated as non-qualified for California tax purposes. Anyone planning to use 529 funds this way should check current Franchise Tax Board guidance or consult a California tax professional before taking a distribution.
529-to-Roth IRA Rollovers
The SECURE 2.0 Act allowed tax-free rollovers from 529 plans to Roth IRAs beginning in 2024. California explicitly does not conform. The Franchise Tax Board treats these rollovers as non-qualified distributions, and the earnings portion is subject to California income tax and the 2.5% additional tax.4Franchise Tax Board. 2024 Instructions for Form FTB 3805P For a California resident, rolling over $7,500 from a 529 with significant accumulated earnings can generate a state tax bill worth weighing against the long-term benefit of Roth growth.
ScholarShare doesn’t offer a state income tax deduction or credit for contributions in the first place, so the state’s only benefit is tax-free growth on qualified withdrawals.5ScholarShare 529 College Savings Plan. Frequently Asked Questions Using the account for a non-conforming purpose erases that benefit on the earnings.
What a Non-Qualified Withdrawal Costs
Taxes and penalties apply only to the earnings portion of a non-qualified withdrawal. Your original contributions come back untouched because they went in with after-tax dollars.
Federally, the earnings are added to your taxable income at your ordinary rate, and the IRS imposes a 10% additional tax on those same earnings.6Internal Revenue Service. 1099-Q What Do I Do? California adds state income tax at your applicable rate plus the 2.5% additional California tax.3ScholarShare 529. How Our 529 Works
Here’s the math on a $10,000 non-qualified withdrawal made up of $6,000 in contributions and $4,000 in earnings. The $6,000 comes back tax-free. The $4,000 in earnings gets hit with federal income tax at your marginal rate, the 10% federal penalty ($400), California income tax at your state rate, and the 2.5% California additional tax ($100). In the 22% federal bracket and the 9.3% California bracket, the total tax on that $4,000 is roughly $1,752.
ScholarShare reports every distribution on IRS Form 1099-Q, which breaks out the gross distribution, the earnings portion, and your basis. The form goes to whoever received the money. If the funds went to the account owner, the 1099-Q arrives in the owner’s name; if paid directly to the beneficiary, the beneficiary receives it.7Internal Revenue Service. Form 1099-Q (Rev. April 2025) – Instructions for Recipient The recipient is responsible for determining whether the distribution was qualified and reporting any taxable earnings.
Exceptions That Waive the 10% Federal Penalty
Several situations waive the federal 10% additional tax on earnings even though the withdrawal is technically non-qualified. In each case the earnings are still subject to ordinary federal income tax and California income tax. Only the 10% penalty goes away.
- Death or permanent disability of the beneficiary.
- An amount equal to any tax-free scholarship, fellowship, or Pell grant the beneficiary receives.
- An amount equal to tax-free veterans’ educational assistance received by the beneficiary.
- An amount equal to the cost of attendance at a U.S. military academy, if the beneficiary attends one.
- An amount matching tax-free employer-provided educational assistance.
Families run into the scholarship exception most often. A common mistake is assuming a scholarship means you should leave the 529 alone. Withdrawing the scholarship-equivalent amount often makes sense: the earnings are taxable, but the 10% penalty is waived, and the account owner recovers funds that would otherwise sit idle if education costs are already covered.2Internal Revenue Service. Publication 970 (2025), Tax Benefits for Education
Recontributions After a Tuition Refund
If the school issues a tuition refund (from dropping a class, withdrawing mid-semester, or receiving a late scholarship) and you originally paid that expense with 529 money, you have 60 days from the refund date to recontribute the funds into any 529 plan for the same beneficiary. If you meet the deadline, the IRS treats the transaction as if the non-qualified distribution never happened, and no tax or penalty is owed on the earnings.2Internal Revenue Service. Publication 970 (2025), Tax Benefits for Education
Miss the 60-day window and the refunded amount becomes a non-qualified distribution, triggering income tax and the 10% federal penalty on the earnings portion. Schools don’t coordinate with 529 administrators on this. Tracking the refund date and acting quickly is entirely on the account owner.
Coordinating With Education Tax Credits
You can claim the American Opportunity Tax Credit or Lifetime Learning Credit in the same year you take a tax-free 529 distribution, but the same dollar of expense cannot support both. The IRS requires you to reduce your qualified education expenses by any amount used to calculate an education credit before determining how much of your 529 withdrawal is tax-free.2Internal Revenue Service. Publication 970 (2025), Tax Benefits for Education
The American Opportunity Credit is worth up to $2,500 and is based on $4,000 in qualifying expenses. Many families do best by paying the first $4,000 of tuition out of pocket or from non-529 savings to capture the full credit, then covering the remaining expenses with 529 withdrawals. Running both against the same expenses doesn’t double the benefit. It just shrinks the tax-free portion of the 529 distribution and can create a partially taxable withdrawal that wasn’t necessary.
Same-Year Timing and Records
The calendar-year matching rule trips up more account owners than any other procedural requirement. Your 529 withdrawal has to happen in the same calendar year as the qualified expense it covers, not the same academic year. If you pay spring-semester tuition in January 2026 but don’t pull the 529 funds until February 2027, the IRS sees that withdrawal as unmatched and potentially non-qualified. For tuition bills that arrive in December for a January semester, watch closely whether your payment posts before or after December 31.
Requesting funds through the ScholarShare portal is straightforward. You can direct the money to the school, to yourself, or to the beneficiary. Paying the institution directly simplifies documentation, but the payment and withdrawal still need to land in the same tax year.
The IRS generally requires you to keep supporting documents until the statute of limitations expires for the return, typically three years from filing, or six years if you underreport income by more than 25%.8Internal Revenue Service. Topic No. 305, Recordkeeping For 529 withdrawals, holding records for at least six years is the safer practice, since the IRS could argue that unreported earnings extend the limitations period. Keep tuition invoices, receipts for books and supplies, housing contracts or leases, and the school’s Form 1098-T for every year you take distributions. The burden of proving a withdrawal was qualified always falls on the account owner, and documentation gaps almost always resolve in the IRS’s favor.
