For eighteen years, the Trump Account is a closed box: your money and the government’s $1,000 go in, nothing comes out. A lot of parents assume the box opens at 18. It doesn’t - it changes shape. The year your child turns 18, the account automatically converts into a Traditional IRA in their name, and a short window of decisions opens with it.

Here’s what actually happens, in order.

January 1 of the Year They Turn 18

The automatic conversion happens on the first day of the year the account holder turns 18, per U.S. Bank’s program guide. Not on their birthday - on January 1. A kid born in December gets the conversion for their whole 18th calendar year; a January baby effectively gets it the year they turn 17 going on 18. Plan around the calendar year, not the birthday cake.

Two things change at conversion:

They take control. The child becomes the account holder in full. Investments, beneficiary designations, the works. Depending on the custodian, they may also get a wider menu of investments than the program’s default index funds.

The childhood contributions stay withdrawable tax-free. Money the family put in was already taxed, so pulling that portion back out doesn’t trigger income tax again. (Early-withdrawal penalties are a separate question - see below.) Growth and the $1,000 seed are the taxed portions.

The Fork: Traditional by Default, Roth by Election

Left alone, the account is a Traditional IRA: growth was tax-deferred, withdrawals in retirement are taxed as income, and required minimum distributions eventually kick in at age 73 under current law.

The alternative is electing to convert to a Roth IRA: pay income tax on the conversion now, and nothing is ever taxed again. With an 18-year-old’s presumably tiny income, that looks like a free lunch. It usually is close to one - with a kiddie-tax trap for dependents that most summaries skip. The strategy and its catch are a post of their own here.

The Rules They Inherit

Whatever the fork choice, your kid is now holding a retirement account, with retirement-account rules:

  • Withdrawals before 59 1/2 are taxed as income where applicable, plus a 10% early-withdrawal penalty - with the usual IRA exceptions (first home, qualified education, disability, and a few others).
  • Future contributions follow regular IRA limits and need earned income to matter - this stops being a parent-funded account, mechanically, at 18.
  • RMDs at 73 apply if they stay on the Traditional path; a Roth election ends that conversation permanently.

The practical upshot for parents: the account you built becomes a head start your child controls, wrapped in rules that make raiding it unattractive but not impossible. Worth one dinner-table conversation before the conversion year, not after.

If You’re Reading This Before the Account Exists

All of the above is the back half of a deal whose front half is free: claim the $1,000, decide about your own contributions whenever, and let the box do its compounding. To see what’s waiting at the far end - 18, 21, 30 - the calculator runs it with your actual numbers.

And if a “final notice about your child’s account conversion” email ever shows up in your inbox around the conversion year: that’s not how any of this works, and the real portal is a .gov you type yourself.

A quiet note: I’m a parent taking notes, not a tax professional. The program’s rules are still being finalized, custodians vary, and edge cases (disability, death, immigration status) have their own provisions. For the conversion-year decisions especially, an hour with a CPA pays for itself.
