Yes, but you'll need a parent or guardian to co-own the account

Most banks and online financial institutions will not let you open a high yield savings account alone at 17. You are a minor in the eyes of the law, which means you cannot sign a binding contract by yourself. The account must be opened as a custodial account — your parent or guardian is the legal owner, and you are the beneficiary. You can deposit money, watch it grow, and withdraw it, but the adult on the account has the final say on what happens to the money.

Some banks do offer teen checking accounts with debit cards, but these almost never pay the high interest rates you see advertised for savings accounts. A custodial high yield savings account is the real option if you want your money to earn interest while you wait.

The process is straightforward: your parent or guardian goes to the bank's website or branch with you, provides their ID and Social Security number, and provides yours. Most banks ask for a phone number and email address too. The account opens in both names, and you can start depositing immediately.

Key Takeaways

  • A parent or guardian must open and co-own the account with you; you cannot open a high yield savings account in your name alone at 17.
  • Custodial accounts let you deposit, withdraw, and earn interest, but the adult retains legal control of the funds.
  • Online banks often offer higher APY than brick-and-mortar banks, and many have no minimum balance requirement for custodial accounts.
  • Once you turn 18, you can convert the custodial account to a regular account in your name only, or open your own account and transfer the money.

How custodial accounts work

A custodial account is a legal structure that lets a minor hold assets while an adult manages them. The adult is responsible for the account and can make decisions about it, but the money belongs to you — it is not the parent's money to spend on themselves. When you turn 18, the account either converts to your name alone or the funds transfer to an account you control, depending on the bank's rules.

The adult on the account can see all transactions, set up automatic transfers, and contact the bank on your behalf. You can usually log in to your own portal and see your balance and interest earned. Some banks let you set up your own transfers and deposits once you reach a certain age (often 13 or 14), but this varies by institution.

The money in a custodial account is yours legally, even though an adult holds the title. If your parent or guardian passes away or the relationship ends, the account does not disappear — it remains in your name, and a court can appoint a new custodian if needed.

Which banks offer custodial high yield savings accounts

Online banks are your best bet for high APY on a custodial account. Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank all offer custodial savings accounts with APY rates that match or come close to their regular savings accounts. Rates change frequently, so check the current rate before opening.

Traditional banks like Chase, Bank of America, and Wells Fargo offer custodial accounts, but their APY on savings is usually much lower — often under 0.05%. If you want your money to actually earn interest, an online bank is worth the switch.

Some credit unions also offer custodial savings accounts. If your family belongs to a credit union, ask whether they offer them and what the current rate is. Credit union rates vary widely, so it is worth comparing to an online bank.

What you need to bring to open the account

You and your parent or guardian will need government-issued ID — a driver's license, passport, or state ID card. The adult will also need their Social Security number and yours. Have a phone number and email address ready. Some banks ask for a second form of ID or proof of address (a utility bill or lease), though many online banks skip this step.

If you are opening the account online, you can usually complete the whole process in 10 to 15 minutes. The bank will verify your identity and your parent's identity electronically. If you are opening it at a branch, bring the documents with you and allow 20 to 30 minutes.

You do not need to have a job or proof of income to open a custodial account. The bank is not lending you money — you are depositing your own, so they have no reason to check your employment status.

What happens when you turn 18

The process for converting a custodial account to an adult account depends on the bank. Some banks automatically convert it on your 18th birthday. Others require you or your parent to contact them and request the conversion. A few banks close the custodial account and ask you to open a new regular account, then transfer the balance over.

Contact your bank before your 18th birthday to find out their specific process. Ask whether the APY will stay the same after conversion, because some banks offer different rates for different account types. If the rate drops, you can transfer your money to a different bank that offers better terms.

Once the account is in your name alone, you have full control. Your parent or guardian can no longer see the balance or make transactions. You can withdraw all the money, close the account, or keep it open and continue earning interest.

How interest accrues on a custodial account

Interest on a high yield savings account is calculated daily and paid monthly. If the account earns 4.50% APY and you have $1,000 in the account, you earn roughly $3.75 that month (the exact amount depends on the number of days in the month and how the bank calculates daily interest). That interest is deposited into your account, and the next month you earn interest on the original $1,000 plus the $3.75, which is called compounding.

The APY advertised by the bank is the annual rate. If you leave the money untouched for a full year, you will earn that percentage. If you withdraw money mid-month, you earn interest only on the balance you held. If you deposit more money, the new balance starts earning interest immediately.

Interest is taxable income. When you turn 18 or at the end of the tax year, the bank will send a 1099-INT form showing how much interest you earned. If you earned more than $10 in interest, you may need to report it on your tax return (rules vary by state and your parent's tax situation, so ask a tax professional).

Risks and limits to know about

High yield savings accounts are FDIC-insured up to $250,000 per depositor per bank. This means if the bank fails, your money is protected. A custodial account counts as your account for FDIC purposes, so the $250,000 limit applies to you, not to your parent or guardian.

Some banks limit how many withdrawals you can make per month from a savings account. Federal rules no longer cap this, but individual banks may. Check the account terms before opening to see if there are withdrawal limits that would bother you.

The APY on high yield savings accounts changes frequently. The rate you see today may be lower next month. This is not a risk — it is just how the market works. If rates drop and you want a better return, you can transfer your money to a different bank.

One real limit: your parent or guardian can see all transactions and balances. If privacy matters to you, understand that they have full visibility into the account. Some families are comfortable with this; others are not. Have that conversation before opening the account.

Frequently Asked Questions

Can I open the account without my parent being present?

No. The adult must be present or verify their identity electronically during the opening process. Most online banks let you both complete the application together on a video call or in person. Some require the adult to sign documents, which means at least one of you has to visit a branch or use an electronic signature tool.

What if my parent wants to close the account before I turn 18?

Your parent can close a custodial account at any time, since they are the legal owner. However, the money is yours — it should go to you, not to them. If there is a conflict, talk to your parent about why they want to close it. If you are worried about access to your money, consider opening the account at a bank where you can also log in and see the balance yourself.

Do I need a job to open a high yield savings account at 17?

No. Banks do not require proof of income or employment to open a savings account. You can deposit money from gifts, allowance, part-time work, or any other source. The bank's only requirement is that you have a parent or guardian to co-own the account.

Will opening a custodial account affect my credit score?

No. Savings accounts do not appear on your credit report and do not affect your credit score. Credit scores are based on borrowing and repayment history — things like loans, credit cards, and payment history. A savings account is just a place to store money.

Can I have more than one high yield savings account at 17?

Yes. You can open custodial accounts at multiple banks if you want. Some people do this to keep money separate for different goals — one account for college savings, one for a car, one for emergencies. Each account earns interest independently, and each is FDIC-insured up to $250,000.
