You can open a savings account at any age, but the rules change depending on whether you're a minor or an adult

If you're under 18, you'll need a parent or guardian to open the account with you or for you. If you're 18 or older, you can open an account on your own. The specific rules vary by bank — some let a parent open an account in a child's name alone, while others require the parent to be a joint owner. A few banks have special youth accounts designed for teenagers that let them manage money with some parental oversight built in.

The age cutoff of 18 comes from contract law: banks need someone who can legally sign binding agreements. A minor can't sign a contract that holds them to the bank's terms and conditions, so the bank needs an adult to take legal responsibility. Once you turn 18, you have that legal power yourself.

Key Takeaways

  • Children under 18 need a parent or guardian to open a savings account, either as a joint owner or as the sole account holder with parental permission.
  • At 18, you can open your own savings account without anyone else's involvement or permission.
  • Some banks offer youth savings accounts for teenagers that include features like spending limits or parental alerts, but these still require a parent to set up.
  • The bank you choose matters — different banks have different minimum age requirements and different rules about whether parents must stay on the account.

How accounts work for children under 18

When a child opens a savings account, the parent or guardian becomes a joint account holder. This means both the parent and child own the account together, and either one can withdraw money or close it. The parent's Social Security number and credit history are used to open the account, not the child's.

Some banks let parents open a savings account in their child's name alone, with the parent as a custodian rather than a joint owner. In this setup, the parent manages the account but the child is the legal owner. The difference matters if the parent and child later disagree about the money — in a custodial account, the money legally belongs to the child, while in a joint account, it belongs to both of you equally.

A few banks set a minimum age for even a joint account — often 13 or 14 — but many will let you open one for a younger child. Call the bank directly to ask, since this varies widely.

Youth accounts designed for teenagers

Some banks offer accounts specifically for people aged 13 to 17. These accounts often come with features that give teenagers more independence while keeping parents in the loop. For example, a youth account might let a teenager use a debit card to spend money, but send the parent a text alert each time a purchase happens. Some set daily spending limits or require parental approval for withdrawals over a certain amount.

These accounts still require a parent to set up and usually require the parent to remain on the account. The point is to teach money management in a supervised way, not to let a teenager operate completely independently. If you're a teenager interested in this kind of account, ask your bank whether they offer one — not all do.

What happens when you turn 18

Once you turn 18, you can open a savings account entirely on your own. You won't need anyone's permission or signature. You'll need to bring a government-issued ID (like a driver's license or passport) and your Social Security number, and you'll sign the account agreement yourself.

If you already have a joint account with a parent from when you were younger, you have choices. You can leave it as is, with both of you as owners. You can ask the bank to remove your parent as an owner, making it your account alone. Or you can close it and open a new account in just your name. The bank can walk you through each option.

What you'll need to bring to open an account

For a child under 18, you'll need the parent or guardian's government-issued ID and Social Security number, plus the child's Social Security number. Some banks also ask for proof of address, like a utility bill or lease in the parent's name. A few banks ask for the child's birth certificate as proof of age.

For someone 18 or older opening an account alone, bring a government-issued ID and your Social Security number. That's usually all you need. Some banks ask for proof of address if you've moved recently, but many don't require it for a savings account.

Call ahead to ask what your specific bank needs. This saves a trip if you're missing something.

Banks with different rules for minors

Large national banks like Chase, Bank of America, and Wells Fargo all let you open joint accounts for children, though the minimum age and specific rules vary. Credit unions often have similar options. Online banks like Ally and Marcus generally don't offer accounts for minors at all, so if you want to open an account for a young child, you'll need to use a bank with a physical branch or a credit union.

Some banks market youth accounts heavily — for example, Greenlight and GoHenry are apps designed specifically for teenagers to learn money management. These aren't traditional savings accounts but rather prepaid debit cards that parents load with money. They're worth knowing about if you're a teenager or parent looking for something beyond a basic savings account.

The best approach is to call or visit the bank you're considering and ask directly: "What's the minimum age to open an account? Do I need to be a joint owner, or can I be a custodian? What documents do you need?" This takes five minutes and saves confusion later.

Frequently Asked Questions

Can a child open a savings account without a parent?

No. Anyone under 18 needs a parent or legal guardian to open a savings account. The bank requires an adult to sign the account agreement because minors can't legally bind themselves to a contract. Once you turn 18, you can open an account on your own.

What if I'm 18 but my parents want to stay on my account?

You can keep them on it if you both want to. Being 18 means you have the legal right to open an account alone, but it doesn't mean you have to. If your parents want to stay involved, the bank can keep them as joint owners. You can also remove them later whenever you choose.

Do I need a Social Security number to open a savings account as a minor?

Yes. The bank needs your Social Security number to report interest earned on the account to the IRS. If you don't have one yet, you can get one from the Social Security Administration — the process takes a few weeks, so plan ahead if you're opening an account soon.

Can my parent open a savings account in my name without me being there?

Yes, in most cases. Many banks let a parent open a custodial account in a child's name without the child present. However, some banks require the child to be there in person. Call your bank to ask before you go in.

What's the difference between a joint account and a custodial account?

In a joint account, both the parent and child own the money equally and can withdraw it. In a custodial account, the child is the legal owner but the parent manages it until the child reaches a certain age (usually 18 or 21, depending on state law). After that age, the account becomes entirely the child's.
