The White House has opened sign-ups for “Trump accounts,” a new federal savings program under the Big Beautiful Bill that gives eligible children born between Jan. 1, 2025 and Dec. 31, 2028 a $1,000 government-funded deposit into a tax-deferred investment account.

• Families and employers can add up to $5,000 a year (with up to $2,500 from employers), with funds invested in low-cost U.S. stock index funds until age 18, when the money can be used for education, a first home, or a small business.
