Watering the Right Seed: A Parent's Guide to Kids' Savings Accounts

Trump Accounts: the Retirement Savings That Start at Birth

Trump Accounts are the newest (and frequently misunderstood) option, created under the One Big Beautiful Bill Act and available since July 4, 2026. Structurally, think of it as an IRA that starts before the child can even walk. Every child under 18 with a Social Security number is eligible, and depending on birth year, some children get a one-time $1,000 seed deposit from the federal government. A major advantage of these accounts over an IRA is that the child does not need their own earned income to contribute to their account.

The mechanics that matter for planning purposes:

Trump Accounts have a $5,000 annual contribution limit, combined across everyone contributing during the "growth period" (birth through December 31 of the year before the child turns 18).
Who can contribute? Parents, grandparents, anyone - plus employers (capped at $2,500, counted inside the $5,000 limit) - and separately, uncapped contributions from qualifying charities and government entities.
Investment options are restricted to low-cost index funds made up of primarily American equities.
At 18, the account converts into a traditional IRA, and from that point forward the normal IRA rules apply, including the requirement that the child have earned income to contribute further.

The main tradeoff is baked into the last bullet. This money is for retirement. It's locked up in the same sense an IRA is locked up; no penalty-free access for college, a first house, or anything else before the usual IRA distribution rules lock in at 18. If your goal is "help my kid retire well," this is arguably the most powerful account on the list, because decades of compounding starting at birth is hard to replicate any other way. If your goal is anything shorter-term, it's the wrong tool.

529 Plans: Still the Default for Education, with More Flexibility Than People Assume

The 529 hasn't changed much, but it's worth restating what it's good at: tax-free growth and tax-free withdrawals for qualified education expenses, with the parent (or grandparent) retaining control of the account indefinitely; the child never gains ownership the way they do with a custodial account.

While it's certainly something to avoid if possible, unused funds aren't as trapped as they used to be. Beneficiaries can be changed to another family member, and after 15 years, a limited amount can be rolled into a Roth IRA for the beneficiary under conditions added by SECURE 2.0. That said, non-qualified withdrawals still carry income tax plus a 10% penalty on the earnings portion, so a 529 is still fundamentally an education bet, not a general-purpose savings account.

If college, trade school, or K-12 tuition is a real likelihood, the 529 remains the most tax-efficient tool for that specific job.

UGMA/UTMA Custodial Account: Lots of Flexibility, Not Much Control

A custodial account can hold anything - cash, stocks, funds - and can be spent on anything that benefits the child, not just education. That flexibility is the primary appeal.

The tradeoff is control, and it's a real one. The assets legally belong to the child as soon as they land in the account. The custodian manages the account until the child reaches the age of majority (18 or 21, depending on the state and the account terms). At that point, the child gets full, unrestricted access to whatever is in there regardless of what you had planned for it. There's no changing your mind at 17 because you're not sure they're ready.

Custodial accounts also count more heavily against a student in financial aid formulas than a 529 or parent-owned account does, since the assets are considered the child's, not the parent's. For a family that expects to need aid, that's worth knowing before funding one heavily.

Where a custodial account earns its keep is the combination of no restriction on what the money can be used for, and a real tax advantage over just holding the money yourself. Because the assets belong to the child, some of the investment income is taxed at the child's rate rather than your own - a meaningful edge over the parent-owned account described below.

That edge is limited by the "kiddie tax" which works in three tiers for 2026: the first $1,350 of the child's unearned income (interest, dividends, and capital gains) is tax-free, the next $1,350 is taxed at the child's own rate (usually 10%), and anything above $2,700 gets taxed at your marginal rate instead. The custodial account is also simpler to open than a 529 or a Trump Account if you just want a low-friction way to start investing on a child's behalf without committing to a specific future use for the money.

The Parent-Owned Non-Retirement Account: The "Keep it Simple" Option

The beauty of this account is that it isn't a kid's account at all. With that comes the ultimate flexibility. This is simply your own taxable non-retirement account that you've earmarked in your head for your kids' benefit.

No special tax treatment. No contribution limit. No rules on what the money can be used for. And most critically, no loss of control. You decide when, how much, and for what. Whether they take a hard turn at 19 or simply aren't ready to be handed a large lump sum of money, nothing forces your hand. Whether they land a full-ride scholarship to their dream school or decide to head straight into the workforce, you aren't left scrambling to figure out what to do with two decades of 529 savings.

The cost of that flexibility is that it's the least tax-efficient of the four. Dividends and capital gains are taxed at your rate, not sheltered away the way a 529 or Trump Account would be. But for a lot of families, "there's no tax shelter, but I keep full control" is a perfectly reasonable trade for "I lose control but save some money on taxes." It's also the easiest account to open.

Final Thoughts

The honest answer is that, for most families, a combination of several of these accounts is the solution to solving different problems:

Certain the money is for retirement and you're comfortable locking it up for decade? Trump Account
Reasonably confident education expenses are coming and you want the tax advantages? 529
Want the money to legally belong to the child and be usable for anything beneficial to them, and you're comfortable with losing control at 18 or 21? Custodial Account
Want to help your kid financially but aren't ready to hand over the keys, or you're not sure yet what the money is for? Parent-Owned Account

What balance of these options is right varies from family to family. If you'd like to discuss the pros and cons of each of these accounts, and how they fit into your financial plan, don't hesitate to reach out. We would be happy to have that conversation.

Prior to investing in a 529 Plan investors should consider whether the investor's or designated beneficiary's home state offers any state tax or other state benefits such as financial aid, scholarship funds, and protection from creditors that are only available for investments in such state's qualified tuition program. Withdrawals used for qualified expenses are federally tax free. Tax treatment at the state level may vary. Please consult with your tax advisor before investing. Trump Accounts offer tax deferred growth on earnings. Family contributions are made with after tax dollars, and eligible employer contributions may be excluded from the employee’s taxable income. A one time $1,000 federal contribution may be available for eligible children born between 2025 and 2028. Distributions are generally prohibited during the child's growth period and, once permitted, are taxable as ordinary income and may be subject to a 10% IRS early distribution penalty if taken before age 59½. Contribution limits and other restrictions apply, and some rules remain subject to future Treasury and IRS guidance. Consult a qualified tax advisor or financial professional before making decisions. Contributions to a traditional IRA may be tax deductible in the contribution year, with current income tax due at withdrawal. Withdrawals prior to age 59 ½ may result in a 10% IRS penalty tax in addition to current income tax. A Roth IRA offers tax deferral on any earnings in the account. Qualified withdrawals of earnings from the account are tax-free. Withdrawals of earnings prior to age 59 ½ or prior to the account being opened for 5 years, whichever is later, may result in a 10% IRS penalty tax. Limitations and restrictions may apply.}
