You can open a savings account at any age, but the account structure depends on how old you are

A child of any age can have a savings account. A bank cannot legally refuse to open one because someone is too young. What changes is who controls the account and signs the paperwork.

If you are under 18, a parent or legal guardian must open and manage the account with you—this is called a custodial account or minor account. You can deposit money, make withdrawals, and watch your balance grow, but the adult on the account has legal authority over it. Once you turn 18, you can convert to an account in your name alone, or open a separate account without a co-owner.

If you are 18 or older, you can open a standard savings account by yourself. You will need an ID, proof of address, and a Social Security number or tax ID. No parent signature required.

Key Takeaways

  • Children under 18 need a parent or guardian to co-own a custodial savings account, but can use it to deposit and withdraw money.
  • At 18, you can open a savings account in your own name without a co-owner, though some banks may still require a parent's signature if you are a dependent.
  • Different banks set their own minimum age for custodial accounts—some start at birth, others at age 13 or older.
  • Custodial accounts stay under the adult's control until you reach the age of majority in your state, usually 18 or 21.

How custodial accounts work before age 18

A custodial account is a real savings account. Money you deposit is yours. You can withdraw it, and interest accrues on the balance just as it would on an adult account. The difference is that the parent or guardian is the legal owner until you reach the age of majority.

The adult can see all transactions, set withdrawal limits, and close the account. They cannot legally take the money for their own use—the funds belong to you—but they have the power to manage how and when you access it. This is why custodial accounts are often used to teach children about saving: the parent can monitor spending and discuss financial decisions.

When you turn 18, the account automatically converts to your name, or you can open a new account and transfer the balance. Some banks require you to visit in person to complete the conversion; others handle it by mail or online. Check with your bank about their process before your 18th birthday.

Minimum age requirements vary by bank

Banks set their own rules for the youngest age at which they will open a custodial account. Some accept newborns; others have a minimum age of 13 or 16. This is not a legal requirement—it is a business decision each bank makes.

Common minimums are birth (age 0), age 13, and age 16. A few banks have no stated minimum and will open an account for any child whose parent brings documentation. If you want to open an account for a young child, call your bank or check their website to confirm they accept that age.

The minimum age for a standard account (one in your name alone, with no co-owner) is 18 in all states. Some banks will open an account for someone 17 if a parent co-signs, but this is not standard practice.

What you need to open an account under 18

To open a custodial account, bring both the child and the adult to the bank, or complete the process online if the bank offers it. You will need:

  • A photo ID for the adult (driver's license, passport, or state ID)
  • Proof of address for the adult (utility bill, lease, or bank statement dated within the last 60 days)
  • The child's Social Security number
  • A photo ID for the child if they are old enough to have one (school ID, passport, or state ID); for infants and toddlers, a birth certificate usually works

Some banks also ask for a second form of ID or additional proof of address. Online banks may have different requirements—some will not open custodial accounts at all. Call ahead or check the bank's website to confirm what they need before you go in.

Age of majority and account ownership

The age of majority is when you legally become an adult and can control your own accounts. In most states, this is 18. In a few states—Alabama, Nebraska, and Wyoming—it is 19. In Mississippi, it is 21.

When you reach the age of majority in your state, the custodial account converts to an account in your name alone. The parent or guardian's name comes off. You then have full control: you can withdraw all the money, close the account, or keep it open and continue saving.

Some banks require you to visit in person or sign new paperwork to complete the conversion. Others do it automatically. If your bank does not contact you around your 18th birthday, reach out to them to confirm the account has been transferred to your name.

Opening an account at 18 without a co-owner

Once you turn 18, you can walk into any bank and open a savings account in your own name. You do not need a parent's permission or signature. Bring a photo ID, proof of address, and your Social Security number.

Some banks will still ask a parent to co-sign if you are claimed as a dependent on their tax return, but this is not required by law. If a bank insists on a co-signer and you do not want one, you can open an account at a different bank.

Online banks often have faster account opening processes for adults 18 and older. You can complete the entire process on your phone or computer, and the account may be ready to use within hours or days.

What happens to a custodial account if the adult dies or becomes unable to manage it

If the custodian (the parent or guardian) dies or becomes incapacitated, the account does not automatically close. However, the bank may freeze it until a new custodian is appointed or until you reach the age of majority.

If you are a minor and the custodian dies, contact the bank when ready with a copy of the death certificate. The bank will explain what happens next. In some cases, a court may need to appoint a new custodian. In others, the bank will hold the account until you turn 18.

This is rare, but it is worth knowing: if you have a custodial account and something happens to the adult managing it, do not assume the money is lost. Call the bank and ask what options exist.

Frequently Asked Questions

Can a teenager open a savings account without a parent?

No, not until age 18. Anyone under 18 needs a parent or legal guardian to co-own the account. Some banks may allow a teenager to open an account with a parent's permission but without the parent present, though most require both the teen and the adult to be there or to complete the process together online.

What is the difference between a custodial account and a regular savings account?

A custodial account is owned by a minor but managed by an adult until the minor reaches 18. A regular savings account is owned and controlled by the account holder. The money, interest, and features are the same; the difference is who has legal authority.

Do I lose access to my custodial account when I turn 18?

No. The account converts to your name, and you keep all the money in it. You gain full control and the parent's name comes off. The bank handles this automatically or with a straightforward form you sign.

Can a parent take money out of a custodial account?

Legally, no. The money belongs to the child. The parent can manage the account and set rules about withdrawals, but taking the money for personal use is not allowed. In practice, enforcement depends on whether the child or another adult reports it.

What if I am 18 but still in high school—can I open my own account?

Yes. Once you turn 18, you are legally an adult and can open a savings account without a parent's involvement, regardless of whether you are still in school or claimed as a dependent.
