Trump Accounts vs. 529 Plans vs. Roth IRAs: Which Wins for Children's Savings?
Trump Accounts are the newest option in a crowded field of tax-advantaged savings vehicles for children. How they stack up against 529 plans and custodial Roth IRAs depends almost entirely on the child’s circumstances and the family’s goals.
The Tax Structure Comparison
The fundamental tax difference between these account types comes down to when taxes are paid:
529 Plans are tax-exempt: contributions come from after-tax dollars, earnings grow without annual taxation, and withdrawals for qualified education expenses are completely tax-free. This makes them the most tax-efficient option over time when funds are ultimately used for education.
Custodial Roth IRAs share the same structure—after-tax contributions, tax-free qualified withdrawals—but with a critical restriction: contributions cannot exceed the child’s earned income. Most children have none, making Roth IRAs inaccessible in practice until the child works.
Trump Accounts are tax-deferred: contributions are not deductible, earnings grow without annual taxation, but all withdrawals are taxed as ordinary income (with an exemption for the after-tax contribution basis). This makes them less tax-efficient than 529s or Roth IRAs at the point of withdrawal.
A Congressional Research Service analysis modeling a $2,500 investment at 7% annual return over 30 years found the 529 plan produces the highest after-tax value, followed by the Trump Account, followed by a taxable brokerage account.
Where Trump Accounts Win
The key advantage is the absence of an earned income requirement. Any child—regardless of whether they have ever worked a day—can be the beneficiary of a Trump Account funded by parents, grandparents, employers, or nonprofits. This opens long-term tax-deferred compounding to children who cannot access custodial IRAs.
Trump Accounts also allow withdrawals (after age 18) for a broader range of expenses than 529 plans, including retirement, first home purchase, emergency expenses, medical costs, and birth or adoption—in addition to higher education. Families uncertain about whether a child will pursue college may prefer this flexibility.
Where 529s and Roth IRAs Win
For families confident a child will pursue higher education, the 529 plan’s tax-exempt withdrawal treatment is superior. For children with earned income, a custodial Roth IRA dominates: it offers tax-free withdrawals, higher contribution limits ($7,500 vs. $5,000 in 2026), fewer investment restrictions, and allows withdrawals of contributions (not earnings) at any time without penalty.
The Substitution Risk
Families who already use 529 plans or custodial IRAs may redirect existing savings into Trump Accounts rather than adding new savings. Congressional Research Service analysis notes this substitution effect is a known risk with any new tax-advantaged vehicle. The net impact on household savings may be smaller than the headline contribution figures suggest.
