A plain-English guide from How Big a House Can I Buy?
Before picking a savings vehicle for your kid, it helps to get clear on what you're actually funding. Two common goals: retirement, decades away, or a first home purchase, maybe in their late twenties or thirties. The right account looks different depending on which one you're aiming at — and the good news is you don't have to choose just one.
Trump Accounts launched July 4, 2026, and for retirement savings they're hard to beat. Every eligible child born 2025–2028 gets a $1,000 seed contribution from the federal government — free money, on day one. From there, family and employers can add up to $5,000/year combined, and it grows completely tax-deferred as a diversified US stock index fund, just like a traditional IRA.
If the money stays invested until your kid is actually near retirement age, this is about as good a head start as a family can give someone: decades of tax-deferred compounding on top of a government-funded seed. It's a strong "and," not competing with anything else you're already doing — just add it to the mix.
Here's the nuance worth knowing before you assume the Trump Account will cover everything: it's structurally a retirement account. Money can't come out before the child turns 18, and after that it converts into a standard traditional IRA — meaning a withdrawal at, say, age 30 to help buy a first home is treated as an early IRA distribution. That means ordinary income tax on the growth, plus a 10% penalty (only $10,000 of that is exempted under the first-time-homebuyer carve-out).
If a down payment for a first home is a goal you want to fund specifically, parents with the financial means to save in more than one vehicle may want to also open a UTMA custodial account alongside the Trump Account. A UTMA isn't a retirement account, so it doesn't carry any of that early-withdrawal baggage — it simply becomes your child's own asset once they reach adulthood, taxed at long-term capital gains rates when sold, with full flexibility on timing and use.
To make this concrete: assume $5,000/year contributed from birth through age 17 (18 years, $90,000 total) into a diversified US stock index fund at 8% annual growth in each account type. Contributions stop at 18, and the balance keeps compounding untouched until age 30.
Both accounts reach the same $509,253 by age 30 under these assumptions — $90,000 of contributions plus $419,253 of growth. The accounts only start to differ once that money actually comes out.
For a same-day withdrawal at 30, a UTMA nets your child noticeably more — because the gain is taxed once, at capital gains rates, with no early-withdrawal penalty. A Trump Account withdrawn at the same age carries an ordinary-income tax hit on the growth plus a 10% penalty on most of it. That's simply the cost of using a retirement wrapper for a non-retirement goal — not a flaw in the account, just a mismatch with the use case.
Think about what you're funding first, then pick the account (or accounts) that match:
Numbers above assume 8% annual growth, no state tax, and a full lump-sum withdrawal at age 30 — adjust for your own assumptions before treating this as a plan. This is general education, not personalized financial or tax advice; talk to a CPA about what's right for your family.
