The Best High-Yield Savings Account for a Kid or Teen in 2026

Of every account in a family, the one where a low rate does the most damage is the child's. A near-zero rate is bad on any balance, but on a child's it compounds against the longest runway any member of the household has. A dollar parked at 0.40% for a decade is a dollar that quietly underperformed for ten years. Savings rates on this page were last verified recently.

The default kids account at a big bank pays close to the national average of 0.38%. That is the loyalty tax, handed to the youngest person in the house.

Where to actually put it

There are two clean structures, both of which can earn the top rate.

Custodial account (UTMA or UGMA). The account is legally the child's, managed by an adult until the child reaches the age of majority, which varies by state. Opened at a high-yield bank, it earns the same 4.40% APY an adult account would. The trade-off is that the money becomes the child's to control at majority.

Parent-owned, earmarked account. A separate high-yield account in the parent's name, mentally reserved for the child. This keeps control and tax simplicity, at the cost of the money counting as the parent's asset. For college-specific saving, a 529 plan does more than any savings account because the growth is tax-free for education.

Either way, the rule is the same as for adults: it must be FDIC insured, and it should pay the top rate, not the big-bank default. Compare the top insured accounts on the live savings page.

The one tax line to watch

Savings interest counts as a child's unearned income, and unearned income is only taxed once it crosses the annual kiddie-tax threshold set by the IRS. Most modest custodial balances earn interest comfortably under that line, so there is no tax to manage and the high-yield account simply compounds. If the balance is large enough that interest approaches the threshold, check the current figure before assuming the account is tax-free. For a child's savings-account balance, this is usually a non-issue, but it is the one number worth knowing.

Why the rate matters more here than anywhere

The case for a high-yield account is always the gap between the top rate and the default. For a child, multiply that gap by time. A balance that sits for a decade or more at a near-zero rate gives up not just the first year's interest but a decade of compounding on interest never earned. The same balance at the top rate compounds in the child's favor for the entire runway. The Bank Gap Index shows the annual figure; for a child, mentally extend it across the years until they reach the account.

Quick answers

What is the best savings account for a kid? A high-yield account, held as a custodial UTMA or UGMA in the child's name or as a parent-owned earmarked account, paying the top rate instead of the near-zero big-bank default.

Is a kid's savings interest taxed? Only if it exceeds the annual kiddie-tax threshold, which most modest balances stay under.

Are these accounts FDIC insured? Yes, at an FDIC-insured bank, up to the standard coverage limits.
