ADRIANA MORGA, WYATTE GRANTHAM-PHILIPS NEW YORK — Whether you realize it or not, your child may be enrolled in a “Trump Account.”Rolled out earlier this year, the Trump Accounts program allows parents to claim special investment accounts for children who are 18 years old or younger. And some babies and newborns are eligible to receive a one-time $1,000 contribution from the government.

Now, due to automatic enrollment highlighted by President Donald Trump Wednesday, the Treasury Department says that every eligible child with a valid Social Security number has a Trump Account. But parents and legal guardians would still need to formally activate the accounts if they haven’t already. Here’s what you need to know about the accounts.

It’s a savings tool that invests money in the stock market on a child’s behalf. The child can’t access the money until they turn 18 and can use it only for specific purposes, such as paying tuition, starting a business or making a down payment on a home.

All Americans under age 18 are now being automatically enrolled in Trump Accounts . But parents and legal guardians still need to formally claim the accounts in order to activate them — by using the program’s website at trumpaccounts.gov or its mobile phone app.

Trump said Wednesday said that 70 million children will now be enrolled in the accounts, up from 8 million created since their launch in July.

For some babies and newborns, the U.S. Treasury Department will make a one-time, $1,000 “seed” contribution once an account is claimed. Other contributions will need to come out of pocket. Parents can contribute up to $2,500 annually in pretax income, much like they do for retirement accounts. But employers, relatives, friends, local governments and philanthropic groups can also pitch in. Yearly contributions are capped at $5,000, although contributions from governments and charities don’t count toward that total.

Private banks and brokerages will manage the money. When the accounts were originally conceived, investments were restricted to broader index funds. But because of updated rules from the Treasury Department late last month, eligible wealthy investors can now also donate stock from individual companies.

To qualify for the $1,000 seed money, a baby must be a U.S. citizen, have a Social Security number and be born between Jan. 1, 2025, and Dec. 31, 2028. Any parent can open an account for a qualifying child, regardless of the parent’s immigration status.

As part of the initiative’s launch, parents of older children also are encouraged to open accounts, but they won’t get the $1,000 bonus. That money is reserved for babies born during the calendar years of the current Trump administration.

Contributions from some of the country’s wealthiest investors still allow some older children to receive starting money in their Trump Accounts. The Dells, for example, separately committed $6.25 billion to give certain children born between 2016 and 2024 seed money of $250 if their parents open a Trump Account. That money is reserved for kids living in ZIP codes with a median family income of $150,000 or less — and deposits are expected to be made by Friday.

It’s important to note that the child won’t be able to access the money until they turn 18, except in rare circumstances. So the money can’t help with immediate expenses. And disbursements from the accounts will be subject to taxes.

Once a beneficiary of a Trump Account turns 18 years old, they can choose to use the money invested in whatever way they choose. However, Trump account beneficiaries can also choose to roll the investment over to a Roth IRA account.

“You’re extending the life of this thing beyond the 18 years; you’re going all the way out into the child’s potential retirement,” said Myranda Fabian, a certified financial planner with Plante Moran Financial Advisors.

Moving the earnings from a Trump Account to a Roth IRA account will be subject to taxation. Roth IRA accounts allow earnings to grow and to be withdrawn free of taxation when an adult reaches retirement age.

The 529 accounts are meant to invest for qualified educational expenses, such as college tuition, trade school, and student loans, among other expenses. There are several differences between these two accounts, such as 529 accounts grow tax-free, while investment earnings from Trump accounts will be taxed when withdrawn, and 529 account funds can be transferred to eligible family members.

Still, while 529s have stronger tax benefits, they’re also specifically limited to spending on education — there’s more options to park money from Trump Accounts after a child turns 18, such as starting a business or making a down payment on a home.

Fabian recommends parents focus on 529 accounts while also taking advantage of Trump Accounts as an addition to their children’s financial future.

Backers of Trump Accounts say they want to introduce more people to the stock market and give even children born into poverty a chance to benefit from it.

But critics say the accounts also fail to offset the cuts the Trump administration and congressional Republicans have made to other programs that benefit young people and the adults in their lives, including food assistance and Medicaid. And even with government contributions, some warn the Trump Accounts could widen the wealth gap.

Nathan C. Goldman, a professor of accounting at North Carolina State University, notes that at the end of the day, Trump Accounts are another option families can consider when making investments for their children, with solid tax advantages.

Still, affluent families will be more likely to afford the full scope of additional, out-of-pocket investments, Goldman said. A total contribution of $5,000 each year, for instance, would add up to $90,000 for one child over 18 years — and even with starting seed money for some children, or options to make smaller investments, inequities remain.

“It’s designed — especially with this $1,000 seed money — to be ‘an account for everybody,’” Goldman said. “But only some people are gonna be able take advantage of this. Only some people are going to have that ability to do that.”AP Writer Moriah Balingit contributed. Grantham-Philips reported from Chicago.
