What a custodial checking account is

A custodial checking account is a bank account opened in a child's name but controlled by an adult — usually a parent, grandparent, or legal guardian. The adult, called the custodian, manages deposits, withdrawals, and spending until the child reaches the age of majority (18 or 21, depending on your state and the bank). The account belongs to the child legally, but the custodian has signing authority and makes all decisions about how the money moves.

The account sits in the child's name on the bank's records, which means the money is the child's property for tax purposes. When the child turns 18 or 21, the account transfers to their full control — no paperwork required at most banks, though some require a conversation with the branch. Until then, the custodian can deposit money, withdraw funds, set up automatic payments, and monitor spending without asking the child's permission.

Banks offer custodial accounts specifically to teach children about money while keeping parental oversight intact. Some come with debit cards, online banking, or spending limits. Others are basic savings accounts with no card at all. The features vary by bank and by the age of the child.

Key Takeaways

  • A custodial account is opened in the child's name but controlled by an adult until the child reaches 18 or 21.
  • The custodian can deposit, withdraw, and spend the money without the child's consent, but the money legally belongs to the child.
  • The account transfers to the child's full control automatically when they reach the age of majority — no application or approval needed.
  • Most custodial accounts come with a debit card and online access, though some banks offer basic savings-only versions.
  • The money in the account counts as the child's income for tax purposes if it earns interest or comes from the child's own earnings.

How custodial accounts differ from joint accounts

A custodial account and a joint account look similar on the surface — both have an adult and a child's name on them — but they work very differently. In a joint account, both the adult and the child have equal signing authority from day one. Either person can withdraw all the money without permission from the other. In a custodial account, only the custodian can sign checks or authorize withdrawals until the child comes of age.

The tax treatment is also different. Money in a joint account belongs to whoever deposited it, unless you can prove otherwise. Money in a custodial account belongs to the child, period — even if a parent deposited every dollar. This matters if the parent has creditors or faces a lawsuit, because joint account money can sometimes be seized, while custodial account money is legally the child's and harder to reach.

Joint accounts are simpler to set up and require no paperwork beyond what you'd do for a regular account. Custodial accounts require the bank to verify the child's age and identity, and some banks ask for a Social Security number or birth certificate. If you want the child to have some control over the account while you retain oversight, a joint account is faster. If you want full control until a specific age, a custodial account is the right structure.

When the account transfers to the child's control

The transfer happens automatically on the date your state and the bank define as the age of majority. In most states, that is 18. A few states use 21. Some banks set their own age — typically 18 — regardless of state law. When the child reaches that age, the custodian's authority ends, and the account becomes a regular checking account in the child's name alone.

You do not need to file paperwork or visit the bank to make this happen. The bank's system tracks the child's birth date and removes the custodian's access on the trigger date. The child can then withdraw money, change the account settings, close the account, or do anything else an adult account holder can do. Some banks send a notice a few weeks before the transfer; others do not.

If the child is not ready to manage money on their own, you can have a conversation with them before the transfer date and agree on a plan — but you cannot legally prevent the transfer. Once the child reaches the age of majority, the account is theirs to control. Some parents open a new joint account with an adult child if they want to keep shared oversight, but that is a separate choice.

Fees and features to compare

Custodial accounts vary widely in cost and what they include. Some banks charge a monthly maintenance fee ($5 to $15 is common), while others waive the fee if a minimum balance is kept or if direct deposit is set up. A few banks offer custodial accounts with no monthly fee at all. Check the fee schedule before you open the account, because fees add up over years.

Debit card access is standard at most banks, but not all. Some custodial accounts come with a card automatically; others require you to request one. A few banks offer spending controls — you can set a daily limit on how much the child can withdraw or spend, or block certain types of purchases. These tools are useful if you want the child to learn to budget within boundaries.

Interest rates on custodial savings accounts are typically very low — often less than 0.01% annually — though some online banks offer higher rates (0.5% to 1% or more). If the account earns interest, that interest counts as the child's income for tax purposes. If the child has no other income and the interest is under a certain threshold (which changes yearly), no tax return is required. Ask the bank what interest rate they offer and whether they send a tax form (1099-INT) at the end of the year.

Tax implications of custodial accounts

The money in a custodial account is the child's property, so any interest it earns is the child's income. If the account earns more than a certain amount of interest in a year (the threshold changes annually and is set by the IRS), you may need to file a tax return for the child even if they have no other income. For 2024, the threshold is $1,300 in unearned income; check the IRS website for the current year's limit.

If the money in the account came from the child's own earnings — a summer job, babysitting, or a part-time position — that is also the child's income and may require a tax return depending on how much they earned. The custodian does not report the account as their own income, and the money does not count toward the custodian's tax burden.

When the child turns 18 or 21 and takes control of the account, nothing changes for tax purposes — the money was already theirs. The bank will continue to send tax forms to the child's address if the account earns interest. If you are unsure whether a tax return is required, a tax professional can review the account statements and tell you what you owe.

How to open a custodial checking account

Most banks offer custodial accounts, and the process is similar across institutions. You visit a branch or go online, provide the child's name and date of birth, show your ID, and provide the child's Social Security number. Some banks ask for the child's birth certificate as proof of age. The account is opened in the child's name, and you are listed as the custodian.

You can usually fund the account immediately with a deposit or a transfer from another account. The bank will issue a debit card if the account includes one, though it may take a few business days to arrive. You can set up online banking right away so you can monitor the account and set up automatic transfers or bill payments.

If you want to compare options, call or visit the websites of banks in your area and search for "custodial checking account" or "minor's account." Ask about monthly fees, interest rates, debit card availability, and spending controls. Some banks market these accounts heavily; others offer them quietly. Credit unions often have custodial accounts too, and sometimes at lower cost than large banks.

What happens if the custodian dies or becomes unable to manage the account

If the custodian dies or becomes incapacitated, the account does not automatically transfer to another adult. The child's access to the money depends on the account structure and your state's laws. If the child is old enough (usually 18 or older), they can take control of the account themselves. If the child is younger, a court may need to appoint a new custodian or guardian to manage the account.

To avoid this problem, name an alternate custodian when you open the account if the bank allows it. Not all banks offer this option, but some do. If your bank does not, you can update your will to name someone to take over custodial accounts in the event of your death. Talk to a lawyer about the best way to structure this for your situation, especially if the account holds a significant amount of money.

If you become unable to manage the account due to illness or disability, you can authorize another adult to act on your behalf by giving them power of attorney. This is a legal document that lets someone else sign checks and make withdrawals in your name. The bank will need to see the power of attorney document before they honor it.

Frequently Asked Questions

Can a child withdraw money from their custodial account without the parent's permission?

No, not until they reach the age of majority. Only the custodian can authorize withdrawals. Once the child turns 18 or 21 (depending on the bank and state), they have full control and can withdraw money without asking permission.

Does money in a custodial account count against financial aid for college?

Yes, it usually counts as the student's asset on the FAFSA (Free Application for Federal Student Aid). Student assets reduce the amount of aid the student is considered to need. The impact varies by school and by how much money is in the account. Talk to the college's financial aid office about how they treat custodial accounts.

What if the child wants to close the account before they turn 18?

Only the custodian can close the account while the child is a minor. If the child wants to close it, you would need to agree and go to the bank together to do so. Once the child reaches the age of majority, they can close it on their own.

Can I use money from the custodial account to pay for the child's expenses?

Yes. The money belongs to the child, but as the custodian, you can withdraw it to pay for their food, housing, education, or other needs. You are not required to ask the child's permission or keep detailed records, though it is good practice to do so if the child is old enough to understand.

Do I need to report the custodial account to the IRS?

You do not report the account itself to the IRS. If the account earns interest or the child has other income, you may need to file a tax return for the child depending on how much they earned. The bank will send a tax form (1099-INT) if interest exceeds the reporting threshold.
