You can open a savings account at 17 without a parent only at a handful of banks that choose to allow it; most banks will require an adult co-owner because, under contract law, anyone below the age of majority can void the account agreement at will. Whether a solo account is available to you is a policy question for the specific bank, not a legal right, so the practical answer depends on where you apply.
Why Most Banks Won’t Let a Minor Open an Account Alone
The reason is a doctrine called the infancy doctrine. A person who has not yet reached the age of majority can cancel almost any contract they sign, and a bank treats its account agreement as a contract. If a minor could walk away from the terms, including fees and obligations, the bank would have little recourse. Requiring an adult co-signer with full legal capacity keeps the agreement enforceable.
The age of majority is 18 in most states. In Alabama and Nebraska it is 19, and in Mississippi it is 21. Until you hit whichever age applies where you live, any contract you sign on your own is generally voidable at your option, not the bank’s.1Legal Information Institute (LII) / Cornell Law School. Age of Majority That one-sided risk is why banks typically say no to an unaccompanied minor.
Banks That Allow Solo Teen Accounts
A few national banks allow teens aged 16 or 17 to open a savings or checking account as the sole owner, without an adult co-signer. This is a bank-level policy choice. Those banks have simply decided to accept the contract-voidability risk for older teens. Availability is uneven and changes over time, so if opening a solo account matters to you, call the bank before you apply and ask whether they permit a 17-year-old to open an account as the only account holder.
One thing to know: even at banks that offer solo teen accounts, a parent’s involvement may still be required for certain add-on features, such as overdraft protection. The core account can be yours alone; the extras may not be.
Identification You’ll Need
Federal law requires banks to verify your identity before opening any account. Under Section 326 of the USA PATRIOT Act, the bank must collect your full legal name, date of birth, physical address, and taxpayer identification number, which for most people is a Social Security number.2Financial Crimes Enforcement Network.

To verify that information, banks typically ask for a government-issued photo ID: a driver’s license, a state ID card, or a passport. If you do not have a photo ID yet, many banks will accept a combination of your birth certificate and a school ID or other secondary document. The bank has some flexibility in what it accepts, as long as it can form a reasonable belief about your true identity.3Financial Crimes Enforcement Network.

Bring originals, not photocopies. Banks generally will not accept photocopies of IDs during the initial account opening. If you walk into a branch with everything in hand, you can usually finish the application in a single visit.
If You Do Need a Parent on the Account
If your bank won’t open a solo account for a 17-year-old, you still have options. Two structures are common for teen savers, and they are not the same thing.
Joint Accounts
A joint savings account lists you and an adult as co-owners with equal access. Either person can deposit, withdraw, or transfer money without the other’s permission, and both are equally responsible for any fees or negative balance. Because both names are on it, the adult can see every transaction, so a joint account does not give you financial privacy. The upside is that you can actually use the money today. The adult’s legal capacity keeps the account enforceable, which is what makes banks willing to open it in the first place.
Many banks package this as a student savings account, with waived monthly maintenance fees, low or no minimum balance requirements, and opening deposits as small as $25. Interest rates vary widely, and some credit unions and online banks pay above 3% APY on smaller balances.
Custodial Accounts
A custodial account is set up under the Uniform Transfers to Minors Act or the Uniform Gifts to Minors Act. The money legally belongs to you, but an adult custodian manages it until you reach the age set by your state’s law. Deposits are treated as an irrevocable gift. Once money goes in, it is yours, and the custodian cannot take it back for personal use.4HelpWithMyBank.gov.

The custodian has a fiduciary duty to manage the funds in your best interest. A custodian who misuses the money can be removed by a court, required to account for every dollar, and held personally liable for the losses. Control transfers to you automatically at the age set by state law, which defaults to 21 in most states and 18 in a smaller number. A few states let the person creating the account choose a termination age as high as 25.4HelpWithMyBank.gov.

The key practical difference: a joint account lets you withdraw funds right now; a custodial account does not let you touch the money until the custodianship ends.
What Changes When You Turn 18
Reaching the age of majority changes your legal standing, and the account usually follows. Many banks automatically convert a minor’s savings account into a standard adult account once you turn 18. The bank may send paperwork to sign, and the adult co-owner can typically be removed so you become the sole owner. If your bank does not handle the conversion automatically, you can visit a branch and ask for it, or open a new individual account and move your balance.
If you want to switch banks entirely at 18, the process is straightforward. Open the new account first, transfer or withdraw your funds, then close the old account. You can do all of this without a co-signer.
Custodial accounts work on a different clock. Under the Uniform Transfers to Minors Act, the custodian must hand over control at the termination age set by your state’s law. In most states that age is 21, not 18, so turning 18 alone does not automatically unlock a custodial account. Once you reach the applicable age, the custodian is legally required to transfer all remaining assets to you.4HelpWithMyBank.gov.
