You can open a bank account under 18, but a parent or guardian must be involved

Most banks will not let you open an account alone until you turn 18. Instead, you'll open what's called a custodial account or minor account — a real bank account in your name, but with a parent or guardian listed as the custodian. The custodian has legal control until you reach the age of majority (18 in most states, 19 in Alabama and Nebraska, 21 in Mississippi). You can use the account to deposit money, make withdrawals, and build a banking history right now.

The process is straightforward: you and your parent or guardian go to a bank branch together, bring identification for both of you, and complete an process. Some banks also let you start online if a parent verifies their identity. The account opens the same day or within a few business days. There are no income requirements, no credit check, and no minimum balance at most banks — though some require you to keep $25 to $100 in the account to keep it active.

Key Takeaways

  • A custodial account is a real bank account in your name with a parent or guardian as the custodian, and you can use it to deposit and withdraw money right now.
  • You and your parent or guardian must go to the bank together with ID, or some banks allow a parent to verify online while you complete the process.
  • Most banks have no minimum balance requirement for teen accounts, though some require $25 to $100 to keep the account open.
  • Your parent or guardian can see all transactions and has the legal right to withdraw money until you turn 18, so choose someone you trust.
  • When you turn 18, the account automatically converts to a standard adult account and the custodian's control ends, though some banks require you to visit in person to complete the transition.

What you need to bring to open an account

You'll need a government-issued photo ID — a driver's license, state ID card, or passport. Your parent or guardian will need the same. Some banks also ask for a Social Security number, which you should have on your Social Security card or birth certificate.

If you're opening the account in person at a branch, bring both IDs and your Social Security number. If you're opening online (which some banks allow), your parent will need to verify their identity through the bank's app or website — usually by uploading a photo of their ID and answering security questions. The bank will then send you a link to complete your part of the process.

You do not need proof of income, a credit card, or a minimum deposit. Some banks ask whether you have an existing account elsewhere, but that's optional information.

Which banks offer accounts for minors

Nearly every major bank offers a custodial account. Chase, Bank of America, Wells Fargo, Citibank, and US Bank all have teen checking accounts with no monthly fees. Credit unions (which you can find through CO-OP or Allpoint networks) often have lower fees and higher savings rates. Online banks like Ally and Marcus also offer minor accounts, though you'll need to open them with a parent present or through a parent's existing account.

The differences between banks are usually small: some offer debit cards with no spending limits, others cap daily withdrawals at $500. Some include savings accounts with interest; others don't. Some let you set up automatic transfers to teach you about saving. Compare what matters to you — whether you want a physical debit card, whether you want to earn interest on savings, or whether you want parental controls that let your guardian set spending limits.

If you already have a parent with an account at a bank, ask whether that bank lets you open a linked minor account. Many do, and it can speed up the process.

What happens when you turn 18

On your 18th birthday, the custodial account automatically converts to a standard adult account. The custodian's name is removed from the account, and they no longer have legal access to your money or the ability to see your transactions. You keep the same account number, debit card, and routing number — nothing changes except the legal structure.

Some banks require you to visit a branch in person to complete the conversion, while others do it automatically without any action from you. Call your bank a few weeks before your 18th birthday to ask what they require. If they need you to come in, you can do it on your birthday or any day after.

Your account history — deposits, withdrawals, and how you've managed the account — stays with you. This history helps you build credit if the bank reports to credit bureaus (many do for teen accounts), and it makes it easier to open other accounts or borrow money later.

How custodial accounts work in practice

Once the account is open, you can deposit money by transferring it from another account, having someone send you money directly, or depositing cash at an ATM or branch. You can withdraw money the same way. Your parent or guardian can also deposit money into your account and can withdraw money if they need to — they have full access until you turn 18.

This means your custodian can see every transaction you make. Some banks let the custodian set limits — for example, a daily spending cap of $50 or a requirement that they approve purchases over $100. These controls are optional, and you and your parent can decide together whether to use them.

If you lose your debit card or forget your PIN, you can go to a branch with ID and get a replacement or reset it. If your account is hacked or someone uses your card without permission, the bank's fraud protection covers you the same way it covers adults — you report it, and the bank investigates and refunds unauthorized charges.

Why opening an account under 18 matters

A bank account teaches you how to manage money before you're on your own. You learn how deposits and withdrawals work, how to check your balance, and how to avoid overdraft fees. You get a debit card that works like a credit card but only spends money you actually have.

An account also builds your banking history. If your bank reports to credit bureaus, the account shows up on your credit report as an account in good standing. This history helps you later when you explore for a credit card, a car loan, or an apartment — lenders and landlords see that you've managed money responsibly.

Finally, a bank account is safer than carrying cash. If you lose cash, it's gone. If you lose a debit card, you can cancel it and get a replacement. If someone steals from your account, the bank can reverse the charges.

What to watch out for

Some banks charge monthly fees for teen accounts if your balance falls below a certain amount or if you don't meet other conditions — like making a deposit each month. Read the fee schedule before you open the account. Most major banks waive fees for minors, but some regional banks don't.

Overdraft fees are another trap. If you spend more than you have in your account, the bank charges you a fee (usually $25 to $35) and may deny the transaction. Some banks let you opt out of overdraft protection, which means transactions straightforward decline instead of charging a fee. Ask your bank about this when you open the account.

Remember that your custodian can see your transactions and withdraw your money until you turn 18. If you're saving for something private, talk to your parent about it first. Some families agree that certain savings are off-limits, but that's a conversation between you and your custodian, not a bank rule.

Frequently Asked Questions

Can I open a bank account without a parent or guardian?

No. Banks require a custodian to be listed on the account until you turn 18. The custodian must be a parent, legal guardian, or in some cases a grandparent or other relative. You cannot open an account with a friend or unrelated adult as the custodian.

What if my parent won't take me to the bank?

Some banks allow a parent to open the account online without you being present, then send you a debit card and PIN in the mail. Call your bank and ask whether they offer this option. If not, you could ask another trusted adult — a grandparent, aunt, or uncle — who has legal guardianship to open the account with you instead.

Will opening a bank account hurt my credit?

No. Opening a bank account does not affect your credit score. A credit score is based on borrowing and repaying money, not on having a checking or savings account. However, if your bank reports the account to credit bureaus, it will show up on your credit report as a positive account in good standing, which can help your credit later.

Can I have more than one bank account?

Yes. You can open accounts at multiple banks if you want. Some people keep a checking account at one bank and a savings account at another to earn higher interest. Each account will have its own custodian listed, so you'll need a parent or guardian to open each one.

What happens if I don't use my account for a long time?

Banks may close accounts that have no activity for 12 months or more. If your account is closed, any money in it will be returned to you or your custodian by check or transfer. To keep your account open, make at least one deposit or withdrawal every few months, or set up a small automatic transfer.
