Yes, you can open a bank account at 16, but nearly every bank in the country will require a parent, guardian, or another adult to join the account as a co-signer or joint owner. No federal law sets a minimum age for holding an account. The catch is contract law: banks won’t enter an agreement with someone who can legally walk away from it, so they attach an adult who can be held to the terms. Once you’ve lined up a willing co-signer and the right paperwork, the rest of the process moves quickly.
Why a Co-Signer Is Required
A bank account is a contract between you and the bank. Under a principle called the infancy doctrine, contracts signed by minors are voidable, meaning the minor can back out but the other party usually cannot. Almost every state sets the age of majority at 18, so anyone younger lacks full capacity to enter a binding agreement on their own.
Banks solve this by adding an adult to the account. The adult signs the contract, takes on responsibility for any overdrafts, fees, or negative balances, and shares full access to the funds along with equal liability. That arrangement stays in place until someone actively changes it, which typically doesn’t happen before the teen turns 18.
Emancipated Minors
In some states, a court can declare a minor legally emancipated, granting the capacity to sign contracts and manage finances independently. An emancipated minor may be able to open an account without a co-signer, but the bank will almost certainly want a certified copy of the court order, and not every bank has a process for handling it. Call ahead before making the trip.
What You and Your Co-Signer Need to Bring
Federal anti-money-laundering rules require banks to verify the identity of everyone opening an account. Both you and the adult co-signer need to provide, at minimum:
- Full legal name, date of birth, and residential address
- A taxpayer identification number, usually a Social Security number
- An unexpired government-issued photo ID (a driver’s license, learner’s permit, or passport all qualify)
These requirements come from the Customer Identification Program rules that apply to every bank in the country.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks
For proof of address, the adult can use a utility bill or lease agreement. For you, a school transcript or report card showing your home address usually works. Make sure the names on your application match your ID exactly. Small discrepancies delay processing.
If You Don’t Have a Driver’s License or Social Security Number
Not every 16-year-old has a driver’s license, and not every applicant has a Social Security number. Banks handle both situations more flexibly than most people expect.
Many banks accept a school-issued photo ID as a secondary form of identification alongside another document such as a Social Security card or utility bill. Policies vary by branch, so ask before your visit.
If you don’t have a Social Security number, some banks and credit unions accept an Individual Taxpayer Identification Number (ITIN), a passport number with country of issuance, or another government-issued identification number.2Consumer Financial Protection Bureau. Can I Get a Checking Account Without a Social Security Number or Drivers License Acceptance varies, so calling around is worth the effort.
Which Type of Account to Open
Most banks offer accounts built specifically for customers under 18. The right choice depends on how you plan to use the money, and nothing stops you from opening more than one.
Teen Checking
Built for everyday spending. You get a debit card, online banking, and the ability to make purchases and ATM withdrawals. Monthly maintenance fees are typically waived while you’re under 18, and minimum balances tend to be lower than standard checking. Expect daily debit card limits around $500 for ATM withdrawals and PIN purchases, with higher caps on signature-based transactions. The co-signer can usually adjust those limits through the bank’s app.
Parental controls are a standard selling point. Real-time spending alerts, the ability to turn the debit card on or off remotely, custom limits by merchant category, and instant card freezes are common features. The specifics differ, so compare apps before choosing where to open.
Minor Savings
Designed for building money over time. It earns a small amount of interest and is usually low-fee or fee-free. Many banks still cap withdrawals at six per month as an internal policy, even though the federal rule that once mandated that limit was eliminated in 2020. If you plan to move money in and out often, checking is the better tool.
Custodial Accounts
Custodial accounts under the Uniform Transfers to Minors Act work differently from joint accounts. An adult opens and manages the account as custodian, but the money legally belongs to you. The custodian controls the funds only until you reach the age of majority, which is either 18 or 21 depending on the state. These fit money being saved on your behalf (gifts from relatives, education savings) rather than day-to-day spending.
Fees and the One Overdraft Rule Worth Memorizing
Teen accounts are among the cheapest products a bank offers, but cheap isn’t free. Monthly maintenance fees are usually waived while you’re under 18 or enrolled in school. Once you age out of the teen product, the account often converts to a standard adult account where monthly fees of $10 to $15 apply unless you keep a minimum balance or set up direct deposit.
Overdraft fees are where teenagers get hurt most. Under federal rules, your bank cannot charge you an overdraft fee on a one-time debit card purchase or ATM withdrawal unless you specifically opted in to overdraft coverage.3Consumer Financial Protection Bureau. 1005.17 Requirements for Overdraft Services That opt-in has to be a separate, affirmative choice. It cannot be buried in the account agreement or required as a condition of opening the account. If you haven’t opted in and a purchase would push you below zero, the transaction is simply declined. No fee.
If you do opt in, overdraft fees at most banks have historically been around $35 per occurrence, though several large banks have reduced or eliminated them in recent years. For a teenager learning to manage money, leaving overdraft coverage turned off is almost always the smarter move. A declined transaction is a small embarrassment; a $35 fee on a $4 coffee is a real loss.
How the Application Works
For an in-person application, you and the adult co-signer visit a branch together with all identification documents. You sign a signature card, hand over your IDs for verification, and make your opening deposit. Online applications are available at many banks. You upload photos or scans of your IDs, fill in your personal information, and submit through the bank’s secure portal.
On the form, your information goes in the primary applicant fields and the adult’s details go in the joint owner or co-applicant section. Check that names, dates of birth, and ID numbers match your documents exactly.
An opening deposit activates the account, usually somewhere between $25 and $50. You can fund it with cash at the branch or a transfer from the co-signer’s existing account. Most banks process applications within one to three business days, and a physical debit card typically arrives seven to ten business days after approval. While you wait, you can usually set up online and mobile banking to view the balance and track initial transactions.
What Changes When You Turn 18
Most teen accounts automatically convert to a standard adult product at 18. Automatic doesn’t mean hands-free. The conversion usually changes the fee structure: monthly maintenance charges may start, minimum balance requirements may rise, and features tied to the teen product may expire.
The adult co-signer also stays on the account until someone takes action to remove them. That means your parent still has full access to the funds, and you’re both still liable. If you want sole ownership, you’ll need to visit a branch, often with the co-signer present, and either remove them from the existing account or close it and open a new individual account in your name only. Eighteen is also a good time to review your overdraft settings and compare student checking products, which may be a better deal than whatever your teen account converts into.
Taxes on the Interest You Earn
Interest paid on a savings account counts as unearned income for tax purposes, even at 16. In practice, a teen’s savings account rarely generates enough interest to create a meaningful tax bill, but the rules exist.
If your interest and other unearned income (dividends, capital gains) total more than $2,700 in a year, a special rule sometimes called the kiddie tax may apply, taxing the excess at your parent’s rate rather than yours. Below that threshold, the tax impact is minimal. If your total unearned income stays under $13,500, your parents can elect to report it on their own return using Form 8814, so you don’t file separately at all.4Internal Revenue Service.
