Yes, you can open a joint high yield savings account, but the bank must allow it and both account holders must be present or complete paperwork together
Most banks that offer high yield savings accounts do allow joint accounts, but not all. Some online banks restrict high yield savings to individual accounts only, while others offer joint options at the same rate as individual accounts. Before you start the process, check the specific bank's account types — this information is usually on their website under account options or FAQs. If the bank does offer joint accounts, both people listed on the account have full access to the money and can make withdrawals or transfers without permission from the other person.
The setup process varies by bank. Some require both account holders to be present in person (rare for online banks), while most online banks let you open the account online with one person signing up and the second person added through a digital process. You will need the second person's Social Security number, date of birth, and address. The bank will verify both identities before the account opens, which typically takes one to three business days.
Key Takeaways
- Not all high yield savings banks offer joint accounts, so confirm the option exists before starting the application.
- Both account holders have equal access to all money in the account and can withdraw or transfer funds without the other person's permission.
- You will need the second person's Social Security number, date of birth, and current address to add them to the account.
- The account will be held as either "joint tenants with rights of survivorship" or "tenants in common," which affects what happens to the money if one person dies.
- Interest earned on a joint account is taxed to both people based on their ownership share, and the bank will issue a 1099-INT form to each account holder.
Which banks offer joint high yield savings accounts
Major online banks that offer joint high yield savings accounts include Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, Discover Bank, and Capital One 360. Traditional banks like Chase, Bank of America, and Wells Fargo also offer joint high yield savings, though their rates are typically lower than online-only banks. Credit unions often have joint savings options as well, and rates vary by institution.
Some banks that do not offer joint high yield savings include Wealthfront, Betterment, and a few smaller online banks. If you want a joint account, you will need to check the specific bank's website or call their customer service line to confirm the option is available. The rate you earn will be the same whether the account is individual or joint — the bank does not charge a premium or discount for adding a second person.
How ownership is structured and what it means for your money
When you open a joint account, the bank will ask how you want to hold the account. The two most common structures are joint tenants with rights of survivorship (JTWROS) and tenants in common. With JTWROS, if one account holder dies, the surviving person automatically owns all the money in the account without going through probate. With tenants in common, each person owns a specific percentage of the account, and if one person dies, their share goes to their estate, not automatically to the other person.
Most couples and family members choose JTWROS because it is simpler and avoids probate. However, if you are opening a joint account with someone who is not a spouse or close family member — for example, a business partner or adult child with their own family — tenants in common may be a better choice so you can control what happens to your share. Ask the bank which option is the default and whether you can choose during setup.
Both people on the account own the money equally unless you specify otherwise. This means either person can withdraw the entire balance without the other person's permission. If you want to restrict access or require both signatures for large withdrawals, a joint high yield savings account is not the right tool — you would need a different account type or a separate arrangement with your bank.
Tax reporting and how interest is split
Interest earned on a joint high yield savings account is reported to both account holders on separate 1099-INT forms. The bank will split the interest based on the ownership percentage you specified when you opened the account. If you did not specify a split, the bank typically assumes 50/50 ownership and reports half the interest to each person.
Each person is responsible for reporting their share of the interest on their own tax return, even if only one person actually receives the money or manages the account. If the split is not 50/50 — for example, if one person contributed 70% of the money — you should tell the bank so the interest is reported correctly. The bank will issue the 1099-INT by January 31 of the following year, and you will need that form to file your taxes accurately.
If you are opening a joint account with a minor, the interest may be taxable to the child at their tax rate, which could be lower than yours. However, there are limits on how much a child can earn tax-free (the standard deduction), so check with a tax professional if the account will earn significant interest.
What happens if one account holder wants to close the account or withdraw money
Either account holder can close a joint high yield savings account or withdraw all the money without permission from the other person. This is a significant risk if you are opening the account with someone you do not fully trust. Before you open a joint account, make sure you are comfortable with the fact that the other person has complete access to the funds at any time.
If one person withdraws money without the other person's knowledge, the bank will not reverse the transaction or step in to mediate. This is a civil matter between the two account holders, not a banking issue. If you are concerned about this risk, consider opening separate accounts instead or using a different account structure that requires both signatures for withdrawals (though high yield savings accounts typically do not offer this option).
If one account holder dies, the surviving person's access depends on the ownership structure. With JTWROS, the surviving person keeps full access and the account continues to earn interest. With tenants in common, the account may be frozen while the estate is settled, which can take weeks or months.
Minimum balances, fees, and rate differences for joint accounts
Most banks do not charge a fee for holding a joint high yield savings account, and the interest rate is the same as for individual accounts. However, some banks have minimum balance requirements — typically $0 to $25,000 depending on the institution. If the balance falls below the minimum, the bank may close the account or reduce the interest rate. Check the bank's terms before you open the account to understand what minimums apply.
A few banks offer slightly different rates based on account type or balance, but this is rare for high yield savings. The rate you see advertised is almost always the rate you will earn on a joint account. Interest is compounded daily and credited monthly or daily depending on the bank, so the more frequently it compounds, the slightly more you will earn.
How to add or remove a person from a joint account
Adding a person to an existing individual high yield savings account is usually possible but varies by bank. Some banks allow you to add a joint owner online, while others require you to call or visit in person. The process is similar to opening a new joint account — you will need the second person's Social Security number, date of birth, and address, and the bank will verify their identity.
Removing a person from a joint account is more complicated. Most banks require both account holders to agree to the removal, and some require you to close the account and open a new one in a single name. If the two people disagree about removing someone, the bank will not remove them without a court order. Before you add someone to an account, understand that removing them later may be difficult or impossible without their cooperation.
Frequently Asked Questions
Do both people on a joint account need to be U.S. citizens or residents?
Most banks require both account holders to have a U.S. address and a valid Social Security number or ITIN (Individual Taxpayer Identification Number). Some banks do not open accounts for non-residents. Call the bank before you start the process if one person does not have a U.S. address or Social Security number.
What if one person on the joint account has bad credit or owes money to the bank?
The bank will not deny a joint account based on one person's credit history, but if either person owes money to that bank, the bank may freeze or offset the account to collect the debt. This is a risk you should discuss with the other person before opening the account. If one person has outstanding debts, consider opening separate accounts instead.
Can I open a joint account with someone who is not a spouse?
Yes. You can open a joint account with an adult child, parent, sibling, business partner, or anyone else. The bank does not restrict joint accounts to married couples. However, understand that the other person has full access to the money, so only open a joint account with someone you trust completely.
Will opening a joint account affect either person's credit score?
No. Opening a savings account does not affect your credit score because it is not a credit product. The bank may do a soft credit check or review your banking history, but this does not show up on your credit report or lower your score.
What if we break up or get divorced?
A joint account does not automatically split during a divorce. The account remains joint unless both people agree to close it or transfer the money. If you are going through a divorce, talk to your lawyer about how to handle joint accounts before you sign any settlement agreement. The court may order the account to be split or frozen during the process.
