You can open a bank account at any age, but the rules depend on whether you're a minor or an adult
If you're under 18, you'll need a parent or guardian to open an account with you or for you. Most banks offer custodial accounts (also called minor accounts) where an adult controls the account until you turn 18 or 21, depending on the bank. If you're 18 or older, you can open an account on your own with just an ID and proof of address.
The specific age at which you gain full control of the account varies by bank. Some banks transfer full ownership at 18; others wait until 21. A few let you take over the account at 16 if you meet other conditions, like maintaining a minimum balance or having direct deposit set up. Check with your bank about when the transition happens and what you need to do to make it official.
Key Takeaways
- Minors can open bank accounts, but a parent or guardian must be present and typically has control over the account until you reach the bank's age of majority (usually 18 or 21).
- At 18, you can open your own account without a parent's involvement, though some banks may still require proof of income or a minimum deposit.
- Custodial accounts often come with restrictions: the adult may need to approve large withdrawals, and you may not be able to close the account without their permission.
- Some banks let you transition to a full adult account before 21 if you meet conditions like setting up direct deposit or keeping a minimum balance.
- Different banks have different rules about account types, fees, and the age of majority, so comparing options before opening is worth your time.
How custodial accounts work for minors
A custodial account is held in your name, but the adult on the account (usually a parent) has legal control. This means the parent can deposit money, withdraw funds, and make decisions about the account. You can use a debit card linked to the account, but the parent may be able to see all transactions and set limits on spending.
The parent's role is to teach you how to manage money while protecting the account from misuse. Some banks let you set up online banking so you can check your balance and see transactions, even if you can't move money without the parent's approval. When you reach the bank's age of majority—usually 18 or 21—the account converts to a standard adult account and you take full control.
Not all custodial accounts are the same. Some banks charge monthly fees for minor accounts; others waive fees until you turn 18. Some require the parent to maintain a minimum balance; others don't. Ask your bank what restrictions apply and when they end.
Opening an account at 18 or older
Once you turn 18, you can walk into a bank or credit union and open an account on your own. You'll need a government-issued ID (driver's license, passport, or state ID) and proof of your current address. A utility bill, lease, or recent bank statement usually works for the address.
Some banks may ask for a Social Security number to run a credit check or verify your identity. Others may ask about your income or employment, though this is less common for basic checking or savings accounts. If you don't have an ID yet, some banks will work with a school ID plus a birth certificate, but policies vary.
You can open an account in person, online, or over the phone, depending on the bank. Online accounts often open faster and sometimes come with no monthly fees. In-person accounts let you ask questions and get help setting up online banking right away.
What happens when a minor account converts to an adult account
The conversion is usually automatic on your birthday or shortly after. The bank will send you a notice explaining that the account has changed and what that means for you. The parent's name may stay on the account as a secondary owner, or it may be removed entirely—this depends on the bank and what you and the parent choose to do.
After conversion, you have full control: you can withdraw money, close the account, add or remove authorized users, and change account settings without the parent's permission. The parent can no longer see your transactions unless you give them permission or keep them on the account as a joint owner.
If the parent stays on the account as a joint owner, they can still access the money and make withdrawals. If you want them off, you'll need to contact the bank and remove them. Some banks let you do this online; others require a visit or a phone call with both parties present.
Age requirements at different types of banks
Traditional banks, credit unions, and online banks all have different policies. Most traditional banks let minors open accounts at any age with a parent, but the age of majority ranges from 18 to 21. Credit unions often have the same rules as traditional banks, though some credit unions are stricter about which minors they accept.
Online banks typically require you to be 18 to open an account on your own, since they can't verify your identity in person. Some online banks do offer custodial accounts for minors, but you'll need to apply through their website with a parent's information. A few online banks let you open an account at 16 if you have a Social Security number and a parent's consent.
If you're under 18 and interested in online banking, check the bank's website for their minor account policy. If they don't offer one, a traditional bank or credit union in your area is your best option.
Documents you'll need to bring
| Situation | Documents Needed |
|---|---|
| Minor opening a custodial account | Parent's ID and proof of address; minor's birth certificate or school ID; Social Security numbers for both |
| 18-year-old opening their own account | Government-issued ID; proof of current address; Social Security number |
| Opening an account without a Social Security number | Passport or consular ID; proof of address; Individual Taxpayer Identification Number (ITIN) if available |
Bring originals, not copies, unless the bank tells you otherwise. If you don't have a current address (for example, if you're homeless or living temporarily), ask the bank what they accept—some will take a shelter address or a friend's address if you have mail there.
What to watch for when opening an account as a minor
Read the account agreement before signing. Look for the age at which you gain full control, any monthly fees, minimum balance requirements, and limits on withdrawals or transfers. Some banks charge fees for overdrafts or out-of-network ATM use, even on minor accounts.
Ask whether the parent can see your transactions online and whether they can set spending limits on your debit card. Some parents want full visibility; others prefer to give their child privacy. Make sure you and the parent agree on what the account rules are before you open it.
Check whether the bank offers financial literacy tools or resources for teens. Some banks have educational content about budgeting, saving, and avoiding debt. These tools can help you build good money habits early.
Frequently Asked Questions
Can a 16-year-old open a bank account without a parent?
Most banks require a parent or guardian to be present for minors under 18. A few banks and credit unions let 16-year-olds open accounts with parental consent but without the parent present, though this is rare. Call your local bank or credit union to ask about their specific policy for 16-year-olds.
What if I don't have a Social Security number?
You can open an account with an Individual Taxpayer Identification Number (ITIN) or a passport. Some banks accept these in place of a Social Security number, though not all do. Call ahead to confirm the bank accepts your form of ID before you visit.
Can I remove my parent from my account after I turn 18?
Yes. Contact your bank and ask to remove the parent as a joint owner or authorized user. Some banks let you do this online; others require a phone call or in-person visit. The parent may need to be present or sign a form, depending on the bank's policy.
Do I need a job to open a bank account at 18?
No. Banks don't require proof of income to open a basic checking or savings account. Some banks may ask about your income or employment, but it's usually optional. If you're a student or don't have a job, you can still open an account.
What's the difference between a custodial account and a joint account?
In a custodial account, the parent has legal control and the minor's name is on the account. In a joint account, both people have equal access and control. Custodial accounts are designed for minors; joint accounts are for adults who want to share an account.
