Under the measure passed by the Senate in a razor-thin vote, the federal government would establish a tax-deferred investment account with $1,000 for every child born in the United States. The program would kick in for children born after Dec. 31, 2024 and before Jan. 1, 2029, aligning with the duration of Trump's second term in office. Beneficiaries could withdraw the cash starting at age 18 under certain circumstances such as paying for college. They would gain full control over the money at age 30, and parents could deposit up to $5,000 annually.
