Yes, minors can open bank accounts, but a parent or guardian must be involved

A person under 18 can open a bank account at most banks and credit unions, but the account will be a custodial account — meaning a parent, legal guardian, or sometimes a grandparent must open it with them and retain legal control until they turn 18. The adult's name appears on the account alongside the minor's name, and the adult can see all transactions and withdraw money at any time.

The specific rules depend on the bank. Some banks allow minors as young as 13 to open accounts with a parent present; others set the minimum at 16. A few banks offer teen accounts designed specifically for this age group, with features like limited overdraft protection or parental monitoring tools. Credit unions often have similar options and sometimes lower minimum balance requirements than large banks.

The account itself works like any other checking or savings account — the minor can deposit money, make withdrawals, use a debit card, and set up direct deposit for paychecks. What changes is that the parent or guardian has the final say on account activity and can close the account or move money without the minor's permission.

Key Takeaways

  • A minor needs a parent, legal guardian, or sometimes a grandparent to open a custodial account; the adult's name is on the account and they retain control.
  • Minimum age varies by bank — some allow accounts at 13, others at 16 — so you will need to check with your specific bank.
  • The minor can use the account to deposit paychecks, make purchases with a debit card, and build banking habits, but the adult can see all activity and withdraw funds.
  • Many banks offer teen-specific accounts with features like parental controls, spending limits, or alerts when money is withdrawn.
  • Once the minor turns 18, the account typically converts to a standard adult account and the parent's control ends.

What happens when you turn 18

When a minor turns 18, the custodial account usually converts automatically to a standard adult account in the minor's name alone. The parent or guardian's name is removed, and they lose access to the account and the ability to withdraw money or see transactions. This happens without the minor having to do anything — the bank handles the conversion based on the birthdate on file.

Some banks require the now-adult account holder to visit a branch or call to confirm the conversion, while others do it entirely in the background. A few banks ask the young adult to sign new account documents reflecting the change in status. Check with your bank about their specific process so you know what to expect on or shortly after your 18th birthday.

How to open a custodial account

The process is straightforward: the minor and the parent or guardian go to the bank together with identification. The bank will ask for the minor's Social Security number and the adult's Social Security number, and they will verify both identities using a driver's license, passport, or state ID. Some banks also ask for proof of address, such as a utility bill or lease.

Many banks now allow you to open a custodial account online or through a mobile app if the parent has an existing account at that bank. In those cases, the parent can initiate the account creation, and the minor may need to verify their identity through the app or by visiting a branch. If you are opening an account at a bank where neither of you has an existing account, you will likely need to visit a branch in person.

Bring both the minor's and the adult's government-issued ID, Social Security numbers, and proof of address if the bank requests it. Some banks also ask about the source of initial deposits — for example, whether money is coming from a paycheck or a gift. Have that information ready to speed up the process.

Debit cards and spending limits for teen accounts

Most custodial accounts come with a debit card for the minor, which works like any other debit card — it draws money directly from the account. Some teen-specific accounts include spending limits that the parent can set, so the minor cannot spend more than a certain amount per day or per transaction. Other accounts have alerts that notify the parent when the minor makes a withdrawal or purchase above a set threshold.

These features are optional and vary by bank. If spending limits or parental alerts matter to you, ask the bank whether they offer them before opening the account. Some banks charge a small monthly fee for accounts with these monitoring features, while others include them at no extra cost.

The debit card can usually be used anywhere Visa or Mastercard is accepted, including online purchases and ATM withdrawals. The minor's name typically appears on the card, and the card is linked to the custodial account, so all transactions show up in the account history that the parent can view.

Building credit and savings habits

A custodial checking or savings account does not build credit on its own — credit bureaus do not track checking or savings accounts, only credit products like credit cards, loans, and lines of credit. However, opening a bank account early helps a young person develop the habit of managing money, tracking spending, and understanding how banks work.

If the goal is to build credit history before turning 18, a parent can add the minor as an authorized user on a parent's credit card. The minor does not need to use the card, but the account activity will show up on the minor's credit report and help establish a credit history. This is different from a custodial bank account but often used alongside one.

Some banks and credit unions offer student credit cards or secured credit cards designed for minors or young adults, though these typically require the minor to be at least 16 or 18. A custodial bank account is the first step; credit-building products come later.

Differences between banks and credit unions

Banks and credit unions both offer custodial accounts, but the terms and features differ. Credit unions are member-owned nonprofits and often have lower fees, lower minimum balances, and more flexible policies around age and documentation. Banks are for-profit institutions and may have higher fees but often offer more branches and ATMs, plus more advanced online and mobile banking tools.

Credit unions typically require membership, which might mean opening a savings account or meeting other criteria. Some credit unions are open to anyone in a geographic area; others are limited to employees of a specific company or members of a specific organization. Check whether you are may be able to access to join a credit union before comparing their custodial account options to a bank's.

Both banks and credit unions are insured by the federal government — banks through the FDIC (Federal Deposit Insurance Corporation) and credit unions through the NCUA (National Credit Union Administration) — so money in the account is protected up to $250,000 if the institution fails.

What you need to know about joint accounts versus custodial accounts

A custodial account and a joint account are not the same thing. In a custodial account, the parent or guardian has legal control and can withdraw money or close the account without the minor's permission. In a joint account, both people have equal rights and either person can withdraw all the money or close the account.

Banks do not typically offer joint accounts to minors because the minor cannot legally enter into a contract. A custodial account is the legal structure designed for this situation. Once the minor turns 18, they can convert the custodial account to a standard account in their name alone, or they can open a true joint account with a parent or another adult if they choose.

If a parent wants to share an account with a minor for convenience — for example, to deposit an allowance or paycheck — a custodial account is the correct and legally sound way to do it.

Frequently Asked Questions

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

No. Banks require a parent, legal guardian, or sometimes a grandparent to open and control a custodial account for anyone under 18. A minor cannot open an account in their name alone. Once you turn 18, you can open your own account without anyone else's involvement.

What if my parent does not have a bank account?

Your parent does not need to have an existing account at the bank to open a custodial account with you. Both of you will go through the account-opening process together, and the bank will collect identification and Social Security numbers for both of you. Your parent will become the account owner and custodian.

Can I use my debit card online and at stores?

Yes. A debit card linked to a custodial account works the same as any other debit card — you can use it at stores, online retailers, ATMs, and anywhere else that accepts Visa or Mastercard. Your parent can see the transaction in the account history, but you can make purchases independently.

What happens if my parent withdraws all the money from my account?

Because your parent is the legal custodian, they have the right to withdraw money from the account. This is one of the key differences between a custodial account and a standard account. If you are concerned about this, talk to your parent about how the account will be managed and what the expectations are around who can spend the money.

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

Yes. Banks require a Social Security number for both the minor and the parent or guardian opening the custodial account. If you do not have a Social Security number, you will need to explore for one through the Social Security Administration before opening a bank account.
