What happens when your teen turns 18
Most banks automatically convert a teen checking account to a standard adult account on the account holder's 18th birthday, or shortly after. The account itself stays open—you don't need to close it and start over. What changes is the account type in the bank's system, which removes parental monitoring features and may adjust fees, interest rates, or spending limits.
Some banks do this conversion without any action from you or your teen. Others send a notice asking you to confirm the change or to remove yourself as a co-owner. A few require your teen to visit a branch or call to complete the switch. The exact process depends on which bank holds the account.
The timing matters because until the conversion happens, your teen's account may still be subject to parental controls—meaning you can see transactions, set spending limits, or freeze the card. Once the account converts, those controls disappear and your teen has full control.
Key Takeaways
- Most banks convert teen accounts automatically at age 18, but some require a parent or the teen to take action—check with your bank to know which applies to you.
- After conversion, parental monitoring features and spending limits are removed, and your teen becomes the sole account owner.
- If your bank does not convert automatically, your teen can request the change in person, by phone, or online depending on the bank's process.
- Some banks change monthly fees or remove teen-specific perks during conversion, so review the new account terms before the birthday arrives.
- If your teen is under 18 and wants to open a separate adult account at a different bank, they will need a parent or guardian to co-sign.
How to find out your bank's conversion process
Call the customer service number on the back of your teen's debit card or log into your online banking portal and search for "teen account conversion" or "age of majority." Most banks have a written policy that explains whether conversion is automatic or requires action.
If you cannot find the policy online, call and ask directly: "What happens to this teen checking account when the account holder turns 18?" Write down the answer, including whether the bank will send a notice, whether you need to do anything, and what date the conversion takes effect. Ask also whether the account number, routing number, or card will change—this matters if your teen has set up direct deposit or automatic payments.
If your teen is within a few months of turning 18, contact the bank now rather than waiting. Some banks process conversions in batches and may take weeks to complete them after the birthday passes.
What to do if your bank requires action
If your bank does not convert automatically, your teen will need to request the change. The process usually involves one of three routes: visiting a branch in person with a photo ID, calling customer service and verifying their identity, or logging into the online banking app and selecting an option to convert the account.
For in-person visits, your teen should bring their debit card and a government-issued photo ID (driver's license, state ID, or passport). They do not need a parent present, though a parent can come along if your teen prefers. The branch staff will remove the parent from the account and update the account type in the system. This usually takes 10 to 15 minutes.
If your teen calls, the bank will ask them to verify their identity by answering security questions or providing information from the account (such as the last four digits of the Social Security number on file). Some banks will also ask to speak with the parent briefly to confirm consent for removal from the account.
Online conversion is the fastest option if the bank offers it. Your teen logs in, navigates to account settings, and selects "convert to adult account" or similar language. The change usually takes effect when ready or within one business day.
Changes to fees, features, and account terms
Teen checking accounts often come with no monthly fee or a low fee, because they are designed for younger users with smaller balances. Adult accounts may have a monthly maintenance fee—typically $5 to $15—though many banks waive the fee if your teen maintains a minimum balance, sets up direct deposit, or meets other conditions.
Some teen accounts include perks like ATM fee reimbursement, no overdraft fees, or a small interest rate on the balance. These may disappear after conversion. Review the terms of the adult account your teen will move into before the birthday arrives, so you can discuss any changes with them.
Check also whether the adult account includes debit card replacement, fraud protection, and customer service hours. Most major banks offer the same protections for teen and adult accounts, but smaller banks or credit unions may differ. If the adult account is less favorable than the teen account, ask whether your teen can switch to a different account type at the same bank or move to a different bank entirely.
Removing yourself as a co-owner or authorized user
If you are listed as a co-owner on the account, the bank may automatically remove you during conversion, or it may ask for your consent. If you are listed as an authorized user (able to see transactions but not control the account), you will usually remain on the account unless you or your teen request removal.
Some parents want to stay on the account to monitor spending or help with fraud detection. Others prefer to step back completely once their teen turns 18. If you want to stay on the account, contact the bank and ask whether that is possible under the adult account terms—some banks do not allow it.
If you want to be removed, you can request it yourself by calling customer service or visiting a branch. Your teen can also request your removal. Once you are removed, you will no longer see transactions, receive statements, or have any access to the account.
What to do if your teen wants a different bank
If your teen is unhappy with the current bank or wants to move to a bank that offers better rates or features, they can open a new account at age 18 without a parent's signature. However, if they want to open the account before turning 18, you will need to co-sign or be listed as a co-owner.
If your teen is opening a new account at 18 or older, they should bring a government-issued photo ID and proof of address (such as a utility bill, lease, or bank statement). They can open most accounts in person at a branch or online through the bank's website.
Before closing the old account, your teen should make sure all direct deposits, automatic bill payments, and recurring transfers are moved to the new account. Closing an account with pending transactions can cause payments to fail. Most banks allow 30 days to move everything over, but it is safer to wait a full billing cycle to confirm all transfers have cleared.
Frequently Asked Questions
Will my teen's debit card number change when the account converts?
Usually not. Most banks keep the same card number and expiration date during conversion. However, some banks issue a new card with a new number as part of the process. Ask your bank whether the card will change before the conversion date, so your teen can update any stored payment information if needed.
Can I stay on the account after my teen turns 18?
It depends on the bank. Some banks allow parents to remain as authorized users or co-owners on adult accounts; others remove all co-owners at age 18. Contact your bank to ask whether you can stay on the account and what your access will be. If the bank does not allow it, you can ask your teen to add you back as an authorized user after the conversion, though they are not required to.
What if my teen is 18 but still in high school?
The account will convert regardless of school status. Age 18 is the legal threshold for account ownership, not graduation. Your teen will have full control of the account and you will no longer have access unless they choose to add you back as an authorized user.
Do I need to be present when my teen converts the account?
No. Once your teen is 18, they can convert the account on their own by visiting a branch, calling customer service, or using the online app. You do not need to be involved unless the bank specifically asks you to consent to your removal from the account.
What happens if my teen does not convert the account and the bank does not do it automatically?
The account will remain a teen account indefinitely, though your teen will still have full access to it. However, they may continue to be subject to parental controls or spending limits, and they may not be able to perform certain transactions (like opening a linked savings account or explore for a credit product). It is best to convert as soon as possible after turning 18 to avoid confusion.
