Yes, you can open a bank account under 18, but you'll need a parent or guardian to co-sign

Most banks allow minors to open accounts starting around age 13, though some begin at 10 or 12. The account is called a custodial account or minor account, and it works like a regular checking or savings account except a parent or guardian has legal control over it until you turn 18. You can deposit money, withdraw it, use a debit card, and set up direct deposit — but the adult on the account can see all transactions and freeze or close the account if needed.

The exact age requirement and rules depend on the bank. Chase, Bank of America, Wells Fargo, and most regional banks have teen checking accounts starting at age 13. Credit unions often have lower minimums and fewer fees. Online banks like Ally and Discover typically require you to be 18, so they are not an option for younger teens.

You will need to visit a branch in person with your parent or guardian. Bring a government-issued ID (school ID usually works), proof of address, and your Social Security number. The adult will need their ID and proof of address as well. The whole process takes about 30 minutes.

Key Takeaways

  • Most banks let you open a custodial account between ages 10 and 13, with a parent or guardian as co-owner.
  • You can use the account like any other — debit card, direct deposit, online transfers — but the adult can see all activity and control the account.
  • You will need to go to a branch in person with your parent or guardian and bring ID, proof of address, and your Social Security number.
  • Credit unions often have lower fees and simpler requirements than large banks for teen accounts.
  • At 18, you can convert the account to a solo account or open a new one without a co-owner.

What happens at the bank branch

Bring your parent or guardian and both of your IDs. The bank will ask for proof of address — a utility bill, lease, or recent bank statement works. You will also need your Social Security number and your parent's. Some banks ask for a second form of ID if your school ID is your only one.

The banker will explain the account terms: what the monthly fee is (many teen accounts have no fee), what the minimum balance is (often zero), and what the debit card limit is. Some banks cap daily debit card spending at $500 or $1,000 for minors. Ask about this before you sign, because it matters if you plan to use the card for larger purchases.

The adult will sign paperwork giving them access to the account. You will also sign. The bank will issue a debit card on the spot or mail it within a week. You can start using the account when ready, even if the card has not arrived yet — you can transfer money online or go to an ATM.

Differences between teen accounts and regular accounts

A custodial account is legally owned by your parent or guardian until you turn 18. That means they can see every transaction, add or remove money, and close the account without your permission. They cannot force you to spend the money, but they have the right to know where it goes.

Some teen accounts have spending limits built in. Your parent can set a daily debit card limit, a monthly spending cap, or both. A few banks let you turn off online transfers or ATM withdrawals if the parent wants tighter control. These limits are optional — your parent does not have to use them.

At 18, the account automatically converts to a regular account in your name alone, or you can open a new account and move the money. The parent's name comes off. Some banks send you a notice before this happens; others do it silently. Check with your bank about their policy so you are not surprised.

Fees and minimum balances

Most teen checking accounts have no monthly maintenance fee. A few banks charge $5 to $10 per month if you do not keep a minimum balance, but many waive the fee if you set up direct deposit or keep $100 or more in the account.

Overdraft fees vary. Some banks charge $35 per overdraft; others decline the transaction instead and charge nothing. Ask the banker which your bank does, because overdraft fees add up fast if you are not careful. Many teen accounts let you turn off overdraft protection so the card straightforward declines if you do not have enough money.

ATM fees are usually free at your bank's ATMs and free at ATMs in their network. Using an out-of-network ATM typically costs $2 to $3. Debit card replacement is usually free if you lose it or it expires.

Building credit as a minor

A checking or savings account does not build credit. Credit bureaus do not track checking accounts — they only track credit products like credit cards, loans, and lines of credit. You cannot open a credit card in your own name until 18, and even then you will need income and a Social Security number.

Some banks offer a secured credit card for teens 16 and up, where you deposit money as collateral and the bank gives you a small credit limit. Using it responsibly and paying the bill on time does build credit. Ask your bank whether they offer this, because not all do.

For now, a checking account teaches you how to manage money — tracking spending, understanding fees, and keeping a balance. Those habits matter more than credit at your age.

What to do when you turn 18

Your custodial account will convert to a regular account automatically, usually without any action on your part. The parent's name comes off and you become the sole owner. You can keep using the same account, the same debit card, and the same routing number.

At this point, you can open a credit card if you have income, or you can open a new account at a different bank if you want a fresh start. Some people keep their teen account because they are used to it; others switch to an account with better features or lower fees.

If your parent wants to stay involved — for example, if they are helping you pay for college — you can add them back as an authorized user on your account. This is optional and you control whether it happens.

Alternatives if your parent cannot co-sign

If your parent or guardian is not available or willing to co-sign, you have limited options. Some banks will open a teen account with a grandparent, aunt, uncle, or other adult relative as co-owner. Call ahead and ask whether the bank accepts this.

A few credit unions allow minors to open accounts with a school official or counselor as co-signer if a parent is unavailable. This is rare and varies by credit union, so you will need to ask directly.

If no adult can co-sign, you will have to wait until 18 to open an account in your own name. In the meantime, you can ask a parent or guardian to add you as an authorized user on their account, which gives you a debit card and the ability to make transactions, though you do not own the account.

Frequently Asked Questions

Can I open a bank account without my parent knowing?

No. A custodial account requires a parent or guardian to be present and sign paperwork. The bank will not open an account for a minor without an adult co-owner. If you are concerned about privacy, talk to your parent about what information they will see — many parents agree to check the account only occasionally.

What if I want to close my account before I turn 18?

You can ask to close it, but your parent or guardian has the final say. They own the account legally and can refuse. If you want to move your money to a different bank, ask your parent to help you transfer it. At 18, you can close the account yourself without permission.

Can I use my teen account to receive paychecks from a job?

Yes. You can set up direct deposit with your employer and your paycheck will go straight into your account. This is one of the most useful features of a teen account — it keeps your money safe and lets you build a record of income, which matters later when you explore for credit or loans.

Do I need a Social Security number to open an account?

Yes. The bank needs it to report interest earned and to comply with federal law. If you do not have a Social Security number, you will need to get one before opening an account. You can explore at your local Social Security office or online at ssa.gov.

What happens if my parent adds themselves to my account after I turn 18?

They cannot do this without your permission. Once you turn 18, you own the account and only you can authorize who has access to it. Your parent can ask to be added as an authorized user, but you decide whether to allow it.
