Roths v. 529s for Education Savings: Does One Have an Edge?
The beginning of a new school year is officially upon us—meaning that many proactive high-income families are particularly focused on developing tax-efficient education funding strategies. Tax-savvy families may be aiming to amass sizeable Roth savings account balances and planning to tap those tax-free funds to cover education costs. Others may be eying a 529 plan allocation strategy. But for grandparents who have already accumulated significant Roth savings, the question may be—is there any reason to fund a 529 plan when I already have a significant source of tax-free income? While each type of account offers a source of tax-free income, they aren't simply interchangeable. Clients who plan to help pay for grandkids' education should understand the nitty-gritty details of each type of account, considering possible penalties, taxes and even financial aid rules.
Roth IRA v. 529 Plan: The Basics
Roth IRAs are primarily retirement savings vehicles. They're funded with after-tax dollars to generate tax-free income later in life, usually during retirement. The funds can be withdrawn tax-free once the taxpayer reaches age 59 ½. The direct after-tax contributions can be withdrawn tax-free at any time, but any earnings may generate tax liability if the account owner hasn't satisfied the five-year rule (penalties can be waived if the funds are used to cover qualified education expenses).
Similarly, Section 529 education savings plans are funded with after-tax dollars that are permitted to grow on a tax-free basis. 529 plan distributions are not taxed when received so long as they are used to pay for qualified education expenses. A 10% penalty on the earnings portion may apply if the funds are not used for qualified education expenses.
Each savings plan has annual contribution limits. In 2026, the maximum that a client can contribute to a Roth IRA is $7,500 ($8,600 if the client is at least 50 years old). Because income restrictions prohibit high earners from contributing directly to a Roth, many clients fund Roths via a Roth conversion strategy.
The contribution limit for 529 plans is based on the annual gift tax exclusion amount, so clients can contribute up to $19,000 in 2026 ($38,000 for married couples). Clients also have the option of front-loading contributions to a 529 plan by contributing five years' worth of contributions in a single year (up to $95,000 in 2026).
Where Roths and 529 Plans Diverge
It can be difficult for high-income taxpayers to amass significant Roth balances. To contribute, they have to convert IRA funds and pay taxes on the amount converted. Converting small amounts over a period of years is typically recommended to minimize the tax liability. Once the funds reach the Roth, it's incredibly valuable to leave them in place—because the longer they grow, the greater the value of tax-free compounded growth.
529 plans can be super-funded in advance (with a whopping $190,000 per couple). This gives grandkids their own source of tax-free growth that can begin compounding immediately. The amounts are also removed from the client's estate for estate tax planning purposes.
Previously, all 529 plans were considered when determining a child's financial aid eligibility via FAFSA. Today, the rules have changed so that accounts owned by grandparents (and other non-parent relatives) shouldn't impact financial aid. (Colleges that have elected to use the CSS financial aid form do consider all of the student's 529 plan options).
Also under prior law, Roths had an advantage over 529 plans because there was always the risk that the student wouldn't need the funds to cover education costs. Not all kids go to college, and some receive hefty scholarships. The SECURE Act 2.0 leveled the playing field by allowing taxpayers to roll up to $35,000 in Section 529 plan dollars into a Roth IRA opened in the grandchild-beneficiary's name. However, the 529 account must have been open for at least 15 years before the rollover can occur.
Conclusion
Congress has created a plethora of tax-preferred savings options—and high-income clients often can leverage any number of strategies to minimize their tax burden. When it comes to education funding options, the key thing to realize is that not all options are precisely the same. Even for those fortunate enough to have funded a Roth well in advance, adding a 529 plan into the mix can be highly valuable—in that it allows Roth funds to continue to grow even while helping a grandchild pay for college.
