Understanding 529 Plans: A Tax-Advantaged Way to Save for Education
The cost of education can be one of the largest expenses a family faces. Whether you are saving for a child, grandchild, another family member, or even yourself, a 529 education savings plan can provide a tax-efficient way to prepare for those costs. Recent changes to federal law have also made 529 plans more flexible than they once were. In particular, the SECURE 2.0 Act created a potential path for certain unused 529 funds to be transferred to a Roth IRA, helping address one of the traditional concerns about saving too much for education.
What Is a 529 Plan?
A 529 plan, technically known as a Qualified Tuition Program, is a tax-advantaged program designed to help families save for qualified education expenses. Most 529 savings plans are sponsored by states, although you generally do not have to use your home state's plan. The person who establishes the account is the account owner, and the person whose education expenses will be paid from the account is the beneficiary. For example, a parent might establish a 529 account for a child. The parent controls the account and decides when distributions are made, while the child is the beneficiary. One important feature is that the beneficiary can generally be changed to another qualifying family member without triggering federal income taxes. This can provide valuable flexibility when a child receives a scholarship, decides not to attend college, or simply does not use all of the money in the account.
How Does a 529 Account Work?
The account owner contributes money to the 529 plan and selects from the investment choices offered by the plan. Depending upon the plan, those choices may include mutual fund portfolios, index-based investments, fixed-income investments, or age-based portfolios that gradually become more conservative as the beneficiary approaches college age. The investments then have the opportunity to grow over time. When money is needed for qualified education expenses, funds can be withdrawn from the account. Under federal tax law, qualified withdrawals generally come out free of federal income tax, including the investment earnings.
529 funds can be used for a broad range of qualified expenses, including certain:
- College and university tuition and fees
- Books, supplies and required equipment
- Computers, software and internet access
- Room and board for eligible students who meet enrollment requirements
- Registered apprenticeship expenses
- Student loan repayments, subject to a $10,000 lifetime limit per individual
- Elementary and secondary education expenses, subject to applicable limits
- Qualified postsecondary credentialing programs
Federal law expanded the permitted K–12 uses in 2025 to include expenses such as curriculum and instructional materials, certain tutoring, testing fees, dual-enrollment fees and certain educational therapies. Beginning in 2026, the federal annual limit for qualified K–12 distributions increased from $10,000 to $20,000 per beneficiary. Certain postsecondary credentialing expenses also now qualify. State tax treatment can differ from federal treatment, so account owners should review the rules applicable in their state.
How Are 529 Plans Taxed?
529 plans offer three significant potential tax advantages.
- Tax-deferred growth - Investment earnings within a 529 account are not subject to annual federal income taxation. That allows dividends, interest and capital gains to remain invested and potentially compound over time.
- Tax-free qualified withdrawals - When distributions are used for qualified education expenses, the earnings portion of the withdrawal is generally excluded from federal taxable income.
- Possible state income-tax benefits - Although there is no federal income-tax deduction for contributing to a 529 plan, some states provide a state income-tax deduction, credit or other benefit for eligible contributions. The rules vary considerably by state and, in some cases, the benefit is available only for contributions to that state's plan.
Contributions to a 529 account are also considered completed gifts for federal gift-tax purposes. Special rules allow an individual to make a larger contribution and elect to spread the gift over five years for gift-tax purposes, subject to applicable limits and requirements.
What Happens If the Money Isn't Used for Education?
Historically, this has been one of the biggest concerns surrounding 529 accounts. If money is withdrawn for something other than a qualified expense, the earnings portion of the nonqualified distribution generally becomes subject to federal income tax and usually an additional 10% federal tax. Exceptions to the additional tax can apply in certain situations, including when the beneficiary receives a scholarship, attends a U.S. military academy, becomes disabled, or dies. There are also alternatives to simply taking a nonqualified withdrawal. Depending on the circumstances, an account owner may be able to change the beneficiary, leave the money invested for future education, use it for another permitted educational purpose, or potentially transfer a portion to the beneficiary's Roth IRA. That last option is one of the most significant changes made by the SECURE 2.0 Act.
SECURE 2.0: Moving Unused 529 Money to a Roth IRA
Beginning in 2024, SECURE 2.0 allows certain unused 529 assets to be transferred to a Roth IRA established for the 529 beneficiary. This provision can be particularly valuable for parents who worry about overfunding a 529 account. Instead of potentially facing taxes and penalties on unused funds, a portion of the remaining account may eventually help the beneficiary begin saving for retirement.
However, several important restrictions apply:
- The 529 account generally must have been open for more than 15 years.
- The Roth IRA must be maintained for the 529 beneficiary, not the account owner.
- Transfers must generally be made directly from the 529 plan to the Roth IRA.
- There is a $35,000 lifetime limit on 529-to-Roth IRA rollovers for the beneficiary.
- The amount transferred in any one year is subject to the applicable annual Roth IRA contribution limit, taking other IRA contributions into account.
- Amounts attributable to contributions made during the preceding five years, and earnings on those contributions, are not eligible for the rollover.
- Other requirements also apply.
The result is potentially powerful. A child who finishes school with unused money in a long-established 529 account may be able to move some of that money into a Roth IRA and give those dollars decades of additional tax-advantaged growth for retirement. Because Treasury and the IRS continue to address implementation of the 529-to-Roth provisions, account owners should verify current requirements with their 529 provider and tax advisor before initiating a rollover.
Advantages of a 529 Account
Tax-free growth for qualified expenses.
The combination of tax-deferred investment growth and tax-free qualified withdrawals can make a 529 considerably more tax-efficient than saving in a regular taxable investment account.
High contribution capacity.
529 plans generally allow substantially larger account balances than education-oriented accounts such as Coverdell Education Savings Accounts.
The account owner maintains control.
Unlike certain custodial accounts, the beneficiary does not automatically take control of the 529 account upon reaching adulthood. The account owner generally continues to control the investments and distributions.
No federal income limitation for contributors.
High-income families can contribute to 529 plans. There is no federal income phaseout preventing someone from establishing or contributing to an account.
Beneficiary flexibility.
If one beneficiary does not need all of the money, the beneficiary can generally be changed to another qualifying family member without federal income-tax consequences.
Broadening definition of education.
529 accounts are no longer exclusively college savings vehicles. Current federal law permits qualified uses for certain K–12 expenses, apprenticeships, student loans and qualifying postsecondary credential programs.
Potential Roth IRA rollover.
SECURE 2.0 provides an additional option for certain unused balances, reducing some of the concern associated with potentially overfunding an account.
Disadvantages and Considerations
Investment choices are limited.
Unlike a regular brokerage account, a 529 account generally limits the owner to the investment choices provided by the particular plan.
Nonqualified withdrawals can create taxes and penalties.
If money is ultimately withdrawn for a nonqualified purpose, earnings may be subject to income tax and an additional federal tax.
State rules vary.
A distribution that qualifies for favorable federal tax treatment does not necessarily receive identical treatment from every state. State deductions, credits, recapture provisions and definitions of qualified expenses should be considered.
Investment returns are not guaranteed.
Most 529 education savings accounts invest in securities and can decline in value. The appropriate investment allocation may therefore change as the beneficiary gets closer to needing the money.
Financial-aid considerations may apply.
The ownership of the account and the beneficiary's relationship to the owner can affect how a 529 is treated under financial-aid rules.
The Roth IRA rollover rules have restrictions.
The SECURE 2.0 provision does not mean that an unlimited unused 529 balance can simply be converted to a Roth IRA. The 15-year requirement, $35,000 lifetime limit, annual contribution limits and five-year contribution restriction all need to be considered.
Is a 529 Plan Right for You?
A 529 plan can be an effective tool for families who want to prepare for future education costs while receiving valuable tax benefits. The expansion of qualified expenses and the SECURE 2.0 Roth IRA rollover provision have also made these accounts more flexible than they were in the past. However, a 529 account should generally be considered as part of a family's overall financial plan. Before committing substantial amounts to education savings, it is important to consider other priorities such as emergency savings, debt reduction and retirement. The key question is not simply, "How much will education cost?" It is also, "How much can we reasonably afford to save for education while still meeting our other financial goals?" Finding the right balance can allow a 529 plan to become a valuable part of a long-term education and financial planning strategy.
