Minimum age to open a savings account

You must be at least 18 years old to open a savings account in your own name at a bank or credit union. Before 18, you can have a savings account only if a parent or legal guardian opens it as a custodial account (also called a minor's account) and co-signs the paperwork. The adult on the account has full control until you turn 18, at which point the account typically converts to a standard account in your name alone.

Some banks allow the account to stay open after you turn 18 without any action on your part. Others require you to visit in person or call to convert it. Check with your bank about their specific process — it usually takes a few days to complete if paperwork is needed.

Key Takeaways

  • You must be 18 to open a savings account by yourself; younger than that requires a parent or guardian to co-sign a custodial account.
  • A custodial account is controlled by the adult until you turn 18, when it typically converts to an account in your name alone.
  • Some banks convert automatically at 18; others require you to request the conversion in person or by phone.
  • The adult on a custodial account can see all transactions and withdraw money, so choose someone you trust.
  • Once you turn 18, you can open additional accounts without a co-signer, and the original custodial account becomes yours to control.

What a custodial account is and how it works

A custodial account is a savings account held in your name but managed by an adult — usually a parent, grandparent, or legal guardian. The adult deposits money, makes withdrawals, and receives statements. You can see the account and watch your money grow, but you cannot withdraw funds or make changes without the adult's permission.

The adult's role is to manage the account on your behalf until you reach the age of majority, which is 18 in most states. At that point, the account legally becomes yours to control. The adult loses the right to withdraw money or make decisions about it, though they may still be able to see the account if they remain a co-owner (this varies by bank).

Custodial accounts are useful because they let you start saving early and learn how banking works while an adult oversees the account. They also protect the money — the adult cannot spend it on themselves without violating the account agreement.

What happens when you turn 18

When you reach 18, your custodial account does not automatically close or disappear. Instead, it transitions to a standard account in your name. You gain full control: you can withdraw money, set up automatic transfers, close the account, or add features like debit cards or online banking.

The adult who was managing the account loses control at this point. Depending on the bank, they may still appear on the account as a co-owner if they choose to stay involved, but they cannot make withdrawals or changes without your permission. Some banks require the adult to be removed entirely; others let you decide.

If your bank requires action to convert the account, they will usually send a notice before your 18th birthday or shortly after. You may need to visit a branch, call the bank, or complete a form online. This process typically takes a few business days.

Opening a savings account after you turn 18

Once you are 18, you can open a savings account on your own without a co-signer. You will need a government-issued photo ID (driver's license, passport, or state ID), proof of address (a utility bill or lease), and your Social Security number. Some banks also ask for a second form of ID or proof of income, though this is not always required for a basic savings account.

You can open an account in person at a bank branch, over the phone, or online. Online accounts are often the fastest — many take just a few minutes to set up. In-person accounts may take longer if the bank needs to verify your identity or if you want to deposit cash immediately.

If you already have a custodial account at the same bank, you do not need to open a new one. The existing account will convert to your name. However, you are free to open accounts at other banks or credit unions if you want to shop around for better interest rates or lower fees.

Banks and credit unions that offer accounts for minors

Most major banks offer custodial savings accounts, including Chase, Bank of America, Wells Fargo, and Citibank. Credit unions also offer them, often with lower fees and higher interest rates than large banks. If you belong to a credit union through your parents' workplace or school, ask whether they have a youth savings program.

Some banks market accounts specifically for teens and young adults, with features like no monthly fees, no minimum balance, or parental controls that let the adult set spending limits. These accounts work the same way as standard custodial accounts but may include extra tools or incentives to encourage saving.

Online banks like Ally, Marcus, and Discover also offer custodial accounts, though the process is entirely digital — you cannot visit a branch. This can be faster if you are comfortable uploading documents and verifying your identity online, but it means you cannot deposit cash in person.

What you need to open a custodial account

To open a custodial account, the adult will need their government-issued photo ID, proof of address, and Social Security number. You will need your Social Security number as well (or a tax ID if you do not have one yet). Some banks also ask for proof of the adult's income or employment, though this is less common for savings accounts than for checking accounts.

The adult and you (or just the adult, depending on the bank's policy) will need to visit a branch or complete an online application together. If you are very young, the bank may not require your presence — the adult can open the account alone and add you later. If you are a teenager, the bank may want to see you in person to verify your identity.

Once the account is open, the bank will issue a debit card or passbook in your name (or the adult's name, depending on the bank). Some custodial accounts do not include a debit card until you turn a certain age, like 13 or 16, to prevent unauthorized spending.

Age limits and special accounts for young savers

There is no upper age limit for a custodial account — a 17-year-old and a 10-year-old can both have one. However, the account must convert to a standard account when you turn 18, so the custodial structure does not extend into adulthood.

Some banks offer special accounts for children under a certain age, like 13 or 16, with restrictions on withdrawals or debit card use. These are designed to teach financial habits and prevent overspending. Once you age out of the program, the account either converts to a standard youth account or a regular custodial account, depending on the bank.

A few banks offer accounts for children as young as newborns, though these are typically savings accounts with no debit card or withdrawal access until the child is older. These accounts are mainly used by parents and grandparents who want to start saving for a child's future.

Frequently Asked Questions

Can I have a savings account without a parent if I am under 18?

No. Federal banking rules require a custodian — a parent, legal guardian, or other adult — to co-sign any account opened by someone under 18. You cannot open an account on your own until you turn 18.

What if my custodial account does not convert when I turn 18?

Contact your bank and ask about their conversion process. Some banks convert automatically; others require you to request it in person or by phone. The bank should have a procedure in place and can walk you through it. Conversion usually takes a few business days.

Can the adult on my custodial account take the money?

Legally, no. The money in a custodial account belongs to you, not the adult. The adult is a trustee managing it on your behalf. If the adult withdraws money for their own use, they are violating the account agreement and potentially breaking the law. Choose someone you trust to manage the account.

Do I need the adult's permission to withdraw money after I turn 18?

No. Once you turn 18 and the account converts to your name, it is entirely yours. You can withdraw money, close the account, or make any changes without asking anyone's permission. The adult no longer has control.

Can I open multiple savings accounts once I turn 18?

Yes. Once you are 18, you can open as many savings accounts as you want at different banks or credit unions. There is no legal limit. Some people open multiple accounts to take advantage of different interest rates, earn sign-up bonuses, or organize money for different goals.
