You can open a bank account for your child at any age, but the rules change depending on whether you're the account owner or they are

A bank account for a child under 18 comes in two forms: one where you (the parent or guardian) own the account and manage it, and one where your child owns it with your permission and co-signature. You can open the first type at birth. For the second type — where your child has real control — most banks allow it starting around age 13, though some wait until 16 or 18. The age that makes sense depends on what you want the account to do: teach money habits, hold birthday money safely, or let your teenager manage their own paycheck.

The choice between these two types shapes what your child can actually do with the money and when they learn to make spending decisions. A custodial account is safer for young children because you control everything. A teen account gives your child real practice managing money while you still have visibility and can step in if needed.

Key Takeaways

  • You can open a custodial account in your child's name from birth, with you as the owner and manager until they reach the age of majority (usually 18 or 21, depending on your state).
  • Teen checking accounts typically become available between ages 13 and 16, and require your signature alongside your teen's on the account.
  • Your child will need a Social Security number and you will need a government-issued ID to open any account, whether custodial or teen-owned.
  • Custodial accounts automatically transfer to your child's full control at the age of majority, so plan ahead if you want to discuss money management before that happens.

Custodial accounts: you own and manage the money until they're an adult

A custodial account is a bank account registered in your child's name, but you control it completely until they reach the age of majority in your state — usually 18 or 21. You deposit money, withdraw money, and make all decisions. Your child can see the balance and learn from watching it grow, but cannot make transactions without your permission.

Banks allow custodial accounts from birth because the account legally belongs to your child, even though you manage it. You'll need your child's Social Security number and your own government-issued ID (driver's license or passport). Some banks require both parents to sign if both are listed on the birth certificate, though policies vary — call ahead to ask.

Custodial accounts are useful for holding money from relatives, birthday gifts, or child support payments in a way that keeps it separate from your own finances. The money grows in the account (earning interest, though rates are currently low at most banks), and your child learns that money can sit somewhere safe instead of being spent when ready. This type of account is especially helpful if you want to set aside money for your child's future without mixing it with your own household finances.

Teen checking accounts: your child owns it, but you co-sign

A teen checking account is different: your child is the account owner, and you are a co-owner who can monitor activity and set limits. Your teen can use a debit card, make deposits, and withdraw money — but you retain access and can see every transaction. Most banks offer these starting at age 13, though some begin at 16, and a few wait until 18.

To open a teen account, you and your teen both visit the bank together. You'll need your government ID and your teen's Social Security number. Some banks also ask for proof of your teen's identity — a school ID or state ID works, though policies differ. The bank will explain what your teen can and cannot do: typically, they can spend money and check their balance, but cannot take out a loan or open another account without you.

Teen accounts teach real money management because your child experiences the consequences of spending. If they overdraft (spend more than they have), they see the fee. If they save toward something, they watch the balance grow. You can set up alerts so you know when they spend, and many banks let you set daily spending limits or block certain types of transactions. This hands-on experience is often more effective than lectures about budgeting.

What happens when your child turns 18 or 21

When your child reaches the age of majority in your state, custodial accounts automatically convert to regular accounts in their name alone. You lose access unless they add you back as a co-owner. Teen accounts also transition — your teen becomes the sole owner, and you are removed unless they ask you to stay on.

This is why it matters to talk about money before that birthday arrives. If your child has never managed their own account, the sudden full control can be overwhelming. Some families use the year before the transition to gradually give their teen more independence: letting them choose how to spend their allowance, having them pay for their own phone bill from the account, or reviewing statements together monthly.

If you're concerned about your young adult's spending habits, you can discuss staying on the account together after 18, but that requires their agreement and the bank's approval. You cannot force it. Having these conversations early — even when your child is 15 or 16 — gives them time to ask questions and practice before they're fully in charge.

Documents you'll need to bring

For a custodial account, bring your government-issued ID (driver's license, passport, or state ID) and your child's Social Security number. If both parents are on the birth certificate and the bank requires both signatures, bring both IDs.

For a teen account, bring your government ID, your teen's Social Security number, and ideally a second form of ID for your teen (school ID, state ID, or passport). Call the bank first to confirm what they accept, because requirements vary by location and by bank. Some banks are stricter than others about what counts as proof of identity.

If you don't have your child's Social Security number yet, you can request one from the Social Security Administration. The process takes a few weeks, so plan ahead if you want to open an account soon. You can start the request online at ssa.gov or by visiting a local Social Security office.

Why age matters less than what you're trying to teach

The "right" age to open an account depends on your child and your goals, not on what the bank allows. Some families open custodial accounts at birth to hold gifts and teach that money can grow. Others wait until their child is 10 or 12 and can understand what a balance means. Some skip custodial accounts entirely and open a teen account when their child is ready to manage their own spending.

If your child receives regular money — an allowance, birthday gifts, or earnings from chores — an account gives that money a home and makes it visible. If your child is old enough to want a debit card and to spend money independently, a teen account with your oversight is a practical teaching tool. There's no single right answer; the right age is when your child is ready and when you're ready to let them practice. Pay attention to whether your child understands that money in an account is still their money, and whether they can handle seeing their balance go down when they spend.

Frequently Asked Questions

Can I open an account for my child without them being present?

Yes, for custodial accounts — you can open one entirely on your own with just your ID and your child's Social Security number. For teen accounts, most banks require your teen to be present and to sign the paperwork themselves, because they are the account owner. A few banks allow online opening for teens, but this is less common.

What if my child doesn't have a Social Security number yet?

You can request one from the Social Security Administration online or by mail. The process takes a few weeks. Some banks will hold an account open while you're waiting for the number, but most require it before they finalize the account. Call your bank to ask about their specific timeline.

Do I need to be a customer at the bank to open an account for my child?

No. You can open a custodial or teen account at any bank, whether or not you have your own account there. Some banks offer small incentives (like a bonus or waived fees) if you open a linked parent account, but it's not required.

What happens if my teen's account goes negative?

If your teen spends more than they have, the account will overdraft and they'll owe the bank a fee — usually $25 to $35 per overdraft. This is actually a useful lesson: they see when ready that overspending costs money. Many teen accounts let you turn off overdraft protection so the transaction is straightforward declined instead, which prevents the fee but also prevents the purchase.

Can my child have more than one bank account?

Yes. Your child can have a custodial account with you and a teen account at a different bank, or multiple accounts at the same bank. There's no legal limit. Some families do this to separate money (one account for savings, one for spending), though it can also become confusing to manage.
