529 College Savings
529 College Savings
A 529 college savings plan is a state-sponsored account for education expenses. Contributions are often state-tax-deductible, growth is tax-free, and withdrawals for qualified education expenses (tuition, room, board, K-12, student loans, apprenticeships) are tax-free. Recent rules allow Roth conversions and flexible beneficiary changes, making 529s more versatile than ever.
Key takeaways
- 529 plans are offered by states and provide tax-free growth for education expenses; many states offer state-income-tax deductions for contributions.
- Contributions have no federal limits, but gifts above $18,000 per year per person are subject to gift-tax reporting (though not taxes if you stay within lifetime exemption).
- Qualified expenses include tuition, room and board, books, computers, required equipment, and now K-12 tuition (up to $235/year), student loan repayment, and apprenticeship costs.
- As of 2024, unused funds can be rolled to a Roth IRA via a new Roth-rollover feature, allowing tax-free conversion if certain conditions are met.
- Beneficiary changes are now unlimited and penalty-free; you can move funds from one beneficiary to another if the new beneficiary is a family member.
The state-tax-deduction advantage
The primary incentive for 529 plans is state income tax deductions. If you live in a state with high income tax and the state offers a 529 deduction, contributing to a 529 reduces your state taxable income.
Example: You live in New York and contribute $5,000 to a New York 529 plan. New York allows a state income tax deduction for contributions up to $235,000 per beneficiary per year. Your $5,000 contribution reduces your New York state taxable income by $5,000. At a 6.5% state tax rate, you save $325 in state tax. This is an immediate, guaranteed return before any investment is made — similar to the employer 401(k) match.
Not all states offer 529 deductions. Some states (California, Florida, Texas) have no income tax and therefore offer no deduction. Other states limit the deduction to state-resident 529 plans only. If you live in a state with both income tax and a generous 529 deduction, opening an in-state plan is financially sensible.
However, you are not locked into in-state plans. The accounts are portable: you can open any state's 529 plan regardless of residency. Some out-of-state plans have low fees and excellent investment options, which may outweigh the loss of a state tax deduction. If you live in a state with no income tax or no 529 deduction, shop the best funds nationally.
Contribution limits and gift-tax coordination
Federal law does not cap 529 contributions, but the IRS gift-tax rules create a practical ceiling. You can gift up to $18,000 per year per person (2024) without filing a gift-tax return. If you have a child and contribute more than $18,000 to a 529 for that child in one year, you must file Form 709 (gift-tax return), though you do not owe tax if the contribution is within your lifetime exemption.
A married couple can each contribute $18,000 per child without gift-tax reporting, for a total of $36,000 per year per child. Over 15 years of a child's life, that is $540,000 per child funded with minimal gift-tax complexity.
However, 529 plans have a "superfunding" election: you can contribute five years of gifts at once. Contribute $90,000 (five years × $18,000) to a 529 in 2024 and elect to spread it over five years for gift-tax purposes. This allows funding a child's entire college savings in one year using the five-year spread election, without gift-tax tax. Once the five-year period is complete, you can superfund again.
For wealthy families planning to gift significant amounts to education, superfunding is a tax-efficient vehicle. A grandparent with liquidity can contribute $360,000 per grandchild using superfunding ($90,000 × four grandchildren), all tax-free and deduction-generating in states with high income tax.
Qualified education expenses: the expanding definition
Historically, 529 plans were limited to college and university expenses: tuition, room and board, books, and computers. The definition has expanded:
- K-12 tuition: As of 2018, up to $235 per year can be withdrawn for private school K-12 tuition per student. This is modest but helpful for families using private schools.
- Student loan repayment: As of 2024, up to $35,000 lifetime per beneficiary can be withdrawn to repay student loans (the borrower's, their spouse's, or their dependent's loans). This is a significant expansion.
- Apprenticeship costs: Tuition and fees for registered apprenticeships are now qualifying expenses, enabling 529 funding for trade school.
- Books, computers, and required equipment: Basic education supplies remain qualified.
- Room and board: For students attending college at least part-time, reasonable room and board expenses are qualified.
The expanding definition makes 529 plans more flexible. If a child does not attend a four-year university, the account is no longer "wasted." It can fund graduate school, apprenticeships, trade schools, or be converted to Roth (via the new rollover feature).
The Roth rollover game-changer
As of January 2024, the IRS allows rolling unused 529 funds to a Roth IRA without tax or penalty, subject to conditions:
- The 529 account must have been open for at least 15 years.
- The 529 beneficiary must be eligible to contribute to a Roth IRA (meeting income limits).
- The Roth contribution must not exceed the annual limit ($7,000 in 2024).
- The 529 account must have sufficient earnings to trigger a rollover (not all principal, but earnings accumulated over 15+ years).
This rule is transformative. Parents who over-funded a 529 (expecting four years of college) but found the child earned a scholarship or attended a cheaper school can now roll the excess to a Roth IRA. The child then benefits from tax-free growth on education-meant funds that are now available for any purpose in retirement.
Example: Parents fund a 529 with $100,000 for a child born in 2008. The account grows to $180,000 by 2024. The child receives a full scholarship to a state university and needs only $40,000 from the 529 for graduate school. The remaining $140,000 can be partially rolled to Roth IRAs (the child and their spouse each get $7,000 to their respective Roth accounts in 2024 if they have earned income). The bulk of the excess can be rolled to a Roth if the conditions are met, tax-free.
This rollover feature eliminates the "penalty trap" of 529 over-funding. For decades, a parent contributing too much to a 529 faced a 10% penalty on earnings if the money was not used for education. Now, excess can be rolled to Roth without penalty.
Beneficiary changes: flexibility at last
Another recent change: beneficiary changes are now unlimited and penalty-free. Previously, changing the beneficiary on a 529 could trigger tax and penalties if the new beneficiary was not a family member. As of 2024, you can change the beneficiary to any family member without penalty.
"Family member" is broadly defined to include children, grandchildren, parents, siblings, and even in-laws and cousins (to various degrees). This means if one child has a $529 with leftover funds, you can change the beneficiary to a sibling or other family member's child, and that person can use the funds for their education. The definition is expansive and forgiving.
For families with multiple children, this flexibility is powerful. Contribute to a single 529 for the oldest child, then roll excess to younger siblings as needed. No account duplication, no complexity.
Drawback: financial aid impact
One limitation: 529 assets owned by parents reduce financial aid eligibility. The Free Application for Federal Student Aid (FAFSA) counts parent-owned 529s as assets, reducing needs-based aid. A $100,000 529 in a parent's name reduces needs-based aid by approximately $5,200 per year (using the FAFSA aid formula).
A workaround: if a grandparent owns the 529 and the parent is not the beneficiary, the asset is not counted on FAFSA. However, grandparent-to-parent gifts in the student's junior and senior years reduce aid differently. Financial aid is complex, and a 529 strategy should account for FAFSA implications if the family expects need-based aid.
Merit-based scholarships (tied to grades, test scores, or special achievements) are not reduced by 529 assets, making the financial aid impact less severe for higher-performing students.
