For the 2026 tax year, you can put up to $19,000 per beneficiary into a 529 plan without using any of your lifetime gift tax exemption, or $95,000 in one year if you elect five-year superfunding. Tax-free withdrawals for K-12 expenses are capped at $20,000 per beneficiary, and up to $35,000 over the beneficiary’s lifetime can be rolled into a Roth IRA if strict conditions are met. This guide covers contribution limits, qualified expenses, Roth rollover rules, and the tax on non-qualified withdrawals. It is general education, not financial or tax advice. Check your situation with the IRS, your state plan, or a licensed tax professional.
529 Contribution Limits for the 2026 Tax Year
Federal law does not set an annual cap on 529 contributions. What limits contributions in practice is the federal gift tax, since a 529 contribution is treated as a completed gift to the beneficiary.
- Annual gift tax exclusion: For the 2026 tax year, it is $19,000 per recipient, the same as in 2025. Anyone can give up to that amount to a beneficiary’s 529 without filing a gift tax return.
- Married couples: By electing gift splitting, a couple can contribute $38,000 per beneficiary in 2026.
- No income limit: Anyone can contribute to a 529 regardless of income, including grandparents, relatives, and friends.
- Amounts over the exclusion: Gifts above the exclusion require Form 709. The excess usually just reduces the donor’s lifetime exemption ($15 million per person for 2026) and does not trigger tax right away.
Many states give their own residents a state income tax deduction or credit for contributions, with limits and rules that differ widely. Some states offer a benefit only when you use the in-state plan, so check your state’s rules before choosing a plan.
How Five-Year Superfunding Works in 2026
A special election lets you treat one large 529 contribution as if you made it evenly over five years. The contribution then counts against five years of annual exclusions at once.
- 2026 maximum: $95,000 per donor per beneficiary (5 x $19,000), or $190,000 for a married couple who elect gift splitting.
- How to elect: You make the election on Form 709 for the year of the contribution. You must file Form 709 even if no tax is owed.
- Future gifts: In the four years that follow, any other gifts to the same beneficiary count against an exclusion that is already used up. Those gifts may reduce your lifetime exemption.
- If the donor dies early: If the donor dies before the five-year period ends, the portion allocated to years after death goes back into the donor’s estate.
- Partial elections: You can superfund less than the maximum. A $60,000 contribution spread over five years uses $12,000 of each year’s exclusion and leaves $7,000 per year for other gifts at 2026 levels.
The annual exclusion is adjusted for inflation in $1,000 steps, so check the current-year figure before making another large contribution in a later year.
State Aggregate Limits on 529 Accounts
The federal tax code does not set a lifetime maximum. Instead, each state plan sets an aggregate limit, meaning the total balance for one beneficiary above which the plan stops accepting new contributions. These limits generally fall between about $235,000 and more than $600,000 per beneficiary, depending on the plan.
Keep these points in mind:
- The limit usually applies to the account balance, not to total lifetime contributions, so investment growth counts toward it.
- If several accounts for the same beneficiary are held in the same state’s plans, they are usually combined for the limit.
- Once you reach the cap, the account can keep growing from market returns, but the plan will not accept new contributions.
- Plans change their limits from time to time, so check your plan’s current figure.

Qualified 529 Expenses, Including K-12, Apprenticeships, and Student Loans
When withdrawals are used for qualified expenses, the earnings are free from federal income tax. The list of qualified expenses is broader than many families realize, and the 2025 federal tax law (the One Big Beautiful Bill Act, or OBBBA) expanded it further.
Higher Education Expenses
At an eligible college, university, vocational school, or other postsecondary institution, qualified expenses include:
- Tuition and required fees
- Books, supplies, and required equipment
- Computers, software, and internet access used mainly by the student while enrolled
- Room and board for students enrolled at least half-time, up to the school’s cost-of-attendance allowance or actual on-campus housing cost
K-12 Expenses and the $20,000 Cap
Starting with the 2026 tax year, the federal cap on K-12 withdrawals is $20,000 per beneficiary per year, up from $10,000. The cap applies per beneficiary, not per account. It covers expenses for public, private, or religious elementary and secondary schools. Under the 2025 law, qualified K-12 expenses go beyond tuition to include:
- Curriculum and instructional materials, including online materials
- Books
- Tutoring or educational classes outside the home, when the instructor meets the law’s qualification standards
- Standardized test fees, including college admission, AP, and similar exams
- Dual enrollment fees at colleges
- Educational therapies for students with disabilities, provided by a licensed or accredited provider
State tax treatment can differ. Some states have not adopted the federal K-12 rules or the higher cap. In those states, a K-12 withdrawal can trigger state tax or recapture of a deduction you claimed earlier, even when it is tax-free federally.
Apprenticeships and Postsecondary Credentials
529 funds can pay for fees, books, supplies, and required equipment for apprenticeship programs registered and certified with the U.S. Department of Labor. The 2025 law also added recognized postsecondary credential programs, such as trade certifications and professional licensing programs. Qualified costs for these programs include tuition, fees, books, supplies, equipment, exam fees for the credential, and continuing education needed to keep it.
Student Loan Repayment
A 529 plan can pay principal and interest on qualified education loans, up to a $10,000 lifetime limit per borrower. That limit applies separately to the beneficiary and to each of the beneficiary’s siblings. Student loan interest paid with tax-free 529 money cannot also be claimed for the student loan interest deduction.
529-to-Roth IRA Rollover Rules
Under SECURE 2.0, leftover 529 money can be moved into a Roth IRA for the beneficiary without income tax or penalty. The rules are strict:
- 15-year account age: The 529 account must have been maintained for at least 15 years for the beneficiary.
- Five-year lookback: Contributions made in the last five years, and the earnings on them, cannot be rolled over.
- Beneficiary’s Roth only: The Roth IRA must belong to the 529 beneficiary, not the account owner.
- Annual cap: Each year’s rollover is limited to the Roth IRA contribution limit, which is $7,500 for the 2026 tax year for savers under 50. That limit is reduced by any other IRA contributions the beneficiary makes that year.
- Earned income: The beneficiary must have earned income at least equal to the amount rolled over that year.
- Lifetime cap: Total rollovers are limited to $35,000 per beneficiary.
- Direct transfer: The money must move directly from the 529 plan to the Roth IRA custodian (trustee-to-trustee).
Roth IRA income limits do not apply to these rollovers, so a high-earning beneficiary can still use this option. At the 2026 limit, reaching the full $35,000 takes at least five years. The IRS has not fully clarified whether changing the beneficiary restarts the 15-year clock, so talk to your plan administrator before relying on an account that has changed beneficiaries.
Separately, the 2025 law made permanent the option to roll 529 funds into an ABLE account for the beneficiary or a family member. These rollovers count toward the annual ABLE contribution limit.
Penalties on Non-Qualified 529 Withdrawals
Money withdrawn for anything other than a qualified expense is a non-qualified distribution. Only the earnings portion is taxed. Your original contributions come back tax-free, since they were made with after-tax dollars.
On that earnings portion:
- It is taxed as ordinary income to whoever receives the distribution.
- A 10% additional federal tax generally applies.
- Many states also tax it and may recapture state deductions you claimed earlier.
The 10% additional tax, though not the regular income tax, is waived when the withdrawal is made because of:
- The beneficiary’s death or disability
- A tax-free scholarship, veterans’ educational assistance, or employer-provided educational assistance, up to the amount received
- The beneficiary’s attendance at a U.S. military academy, up to the cost of attendance
- Expenses used to claim the American Opportunity or Lifetime Learning credit
Common mistakes include paying expenses in one calendar year and withdrawing the money in another, paying off-campus rent above the school’s allowance, and exceeding the $20,000 K-12 cap by combining withdrawals from several accounts for the same child. Keep receipts that match each withdrawal. Form 1099-Q reports the distribution, but you are the one who has to prove the expenses qualified.
Frequently Asked Questions
How much can I contribute to a 529 plan in 2026 without filing a gift tax return?
For the 2026 tax year, one person can contribute up to $19,000 per beneficiary without filing Form 709. A married couple can contribute $38,000 per beneficiary, but gift splitting requires filing Form 709. Superfunding up to $95,000 per donor also requires a Form 709 election.
Can I use a 529 plan for private school tuition in 2026?
Yes. For the 2026 tax year, up to $20,000 per beneficiary can be withdrawn federally tax-free for K-12 tuition and other qualified K-12 expenses, such as curriculum materials, tutoring, and test fees. Your state may treat these withdrawals differently, so check your state’s rules before withdrawing.
What happens to unused 529 money if my child does not go to college?
You have several options. You can change the beneficiary to another family member without tax, leave the money for future education or credential programs, pay up to $10,000 in student loans, roll up to $35,000 over the beneficiary’s lifetime into a Roth IRA if the account qualifies, or roll funds into an ABLE account. If you simply withdraw the money, the earnings are subject to income tax and generally a 10% additional federal tax, unless an exception applies.
