Yes, you can open a bank account at 17, but in almost every case a parent or guardian has to be on the account with you. That’s because someone under 18 generally can’t sign a binding contract on their own, and a bank account agreement is a contract. The adult joins as a joint owner or as a custodian, and you get to use the account day to day.
Why Banks Want an Adult on the Account
In most states, anyone under 18 lacks full legal capacity to enter a binding contract. A contract signed by a minor is generally “voidable,” meaning the minor can honor it or walk away without the same consequences an adult would face. Banks treat account agreements as contracts, so a 17-year-old acting alone creates a risk the bank can’t easily enforce, including recovering overdrafts or collecting fees.
Attaching an adult to the account solves that. The adult becomes the legally liable party the bank can pursue if the account goes negative or fees pile up. This is industry-wide practice rooted in contract law, not the policy of any single bank. A handful of states have laws that specifically allow minors to hold deposit accounts on their own, but even in those states individual banks often still require an adult as internal policy.
Documents You and the Adult Need to Bring
Federal identification rules apply regardless of age. At a minimum, the bank has to collect your name, date of birth, address, and a taxpayer identification number before opening the account.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks For most U.S. teenagers, the tax ID is a Social Security number; an Individual Taxpayer Identification Number (ITIN) is accepted at many banks if you don’t have an SSN.2Consumer Financial Protection Bureau.

What to expect to bring:
- A government-issued photo ID such as a driver’s license, learner’s permit, passport, or state ID. Some banks accept a school ID paired with another document.
- Your Social Security number or ITIN.
- Proof of address, such as recent mail, a school transcript, or a utility bill.
- An opening deposit. Teen accounts often start at $25, though some banks ask for more.
The adult brings their own government-issued photo ID, Social Security number, and address verification. Some banks also ask the adult for employment and income information and run a soft credit check, which doesn’t affect their score. Opening a basic checking or savings account doesn’t generate a credit report for you as the minor.
If you’ve been legally emancipated by a court, you generally have full capacity to sign the account agreement yourself. Bring the certified emancipation order along with your usual ID. Not every branch employee has handled this before, so call ahead to confirm what they need.
Joint Account or Custodial Account
The adult can be on the account in one of two ways, and they work differently.
Joint Account
A joint account is the most common setup for a 17-year-old. Both of you can deposit, withdraw, and see the full balance. Both names are on the account, and both of you are responsible for any negative balance, unpaid fees, or overdrafts. The bank can pursue either person for what’s owed. This gives you the most hands-on experience running a checking or savings account.
Custodial Account (UTMA or UGMA)
A custodial account under the Uniform Transfers to Minors Act or the older Uniform Gifts to Minors Act works differently. You’re the legal owner of the money, but an adult custodian controls the account and its transactions until you reach the age set by state law.3Cornell Law School Legal Information Institute. Uniform Transfers to Minors Act Money in the account is treated as a gift to you and has to be used for your benefit.
People often assume custodianship ends at 18. It usually doesn’t. Most states set the default UTMA transfer age at 21, some use 18, and a few allow it to be delayed as late as 25. When you hit that age, the custodian’s authority ends and full control passes to you.
Daily Limits and Overdraft Rules
Teen accounts usually have lower daily limits than standard adult accounts. Daily ATM withdrawal caps commonly fall between $100 and $500, and daily debit card purchase limits typically run from $500 to $5,000 depending on the bank. Many banks also let the adult co-owner set custom spending caps, turn the debit card on or off, and get real-time transaction alerts.
On overdrafts, federal rules protect you from surprise fees on everyday debit card purchases and ATM withdrawals. The bank cannot charge an overdraft fee for paying these transactions unless someone on the account has opted in to the bank’s overdraft service in writing. On a joint account, consent from any one holder counts for the whole account, and either holder can revoke it.4Consumer Financial Protection Bureau. Regulation E 1005.17 Requirements for Overdraft Services If nobody opts in, the bank simply declines transactions that would overdraw the account instead of covering them and charging a fee.
Who Pays Tax on the Interest
Interest earned in the account is taxable income, even for a minor. How it gets reported depends on the account type.
On a joint account, the bank reports the interest under whichever Social Security number is listed as the primary taxpayer on the account, usually the adult’s. If the interest really belongs to you because you deposited the money that earned it, the adult may need to file a nominee 1099-INT showing you as the actual recipient.5Internal Revenue Service. Topic No. 403, Interest Received
On a custodial account, the interest is your income. A dependent minor with unearned income above $1,350 in 2026 generally has to file a return.6Internal Revenue Service. Revenue Procedure 2025-32 Inflation-Adjusted Items for 2026 Above $2,700 in 2026, the “kiddie tax” can apply and tax the excess at the parent’s marginal rate instead of yours.7Internal Revenue Service. Topic No. 553, Tax on a Childs Investment and Other Unearned Income (Kiddie Tax) For a typical teen savings balance, these numbers usually don’t come into play. They start to matter if the custodial account is holding larger investment funds.
What Changes When You Turn 18
Turning 18 doesn’t automatically change the account, but it opens new options. Banks handle the transition in one of two ways:
- Some banks automatically convert a teen account to a standard adult checking account on your 18th birthday. Daily spending and ATM limits go up to adult levels, and you may get a new debit card, with the old teen card deactivated shortly after.
- Other banks require you to come into a branch, sign new account documents, or open a fresh individual account. This is also when you can ask to remove the adult co-owner if you want sole control.
Removing the co-owner is not always automatic even after your birthday. Most banks require a signed form from either the primary account holder or the person being removed. Until that’s done, the adult stays on as a joint owner with full access and shared liability. If you want a clean break, opening a new account in your own name and transferring the balance over is often the simplest route.
