Opening a joint high yield savings account requires both account holders to provide identification and Social Security numbers, choose a bank or online institution, and sign the account agreement together—usually in person at a branch or electronically online.
A joint account means two people own the account equally and can both deposit, withdraw, and manage the money. Most online banks and traditional banks offer joint high yield savings accounts with the same interest rates as individual accounts. The main difference is the paperwork: you need both people present (or both signing electronically) to open it, and both people's names appear on the account.
The process typically takes 10 to 15 minutes if you're opening online, or 20 to 30 minutes at a branch. You'll need government-issued ID, Social Security numbers, and an initial deposit—usually $0 to $25 depending on the bank. Some banks require a minimum balance to earn the advertised APY; others do not.
Key Takeaways
- Both account holders must provide a government-issued ID and Social Security number; the bank will verify both identities before opening the account.
- Joint account holders have equal access to all funds and can each withdraw money without permission from the other person.
- The interest rate on a joint high yield savings account is the same as on an individual account at the same bank.
- Online banks typically have higher APYs than traditional banks and allow you to open a joint account entirely through their website.
- If one account holder dies, the surviving holder usually retains full access to the account and all funds in it.
What you need to bring or provide
Both account holders must have a government-issued photo ID—a driver's license, passport, or state ID card. The bank will scan or photograph it. You'll also need both people's Social Security numbers, which the bank uses to verify identity and check for fraud or existing accounts in your name.
If you're opening online, you can upload photos of your ID and enter your Social Security number directly into the bank's website. If you're opening at a branch, bring the physical ID and be ready to provide your Social Security number verbally or on a form. Some banks also ask for a phone number and current address to complete the identity check.
You'll need an initial deposit to fund the account. This ranges from $0 at some online banks to $25 or $100 at others. You can deposit by transferring money from another bank account, mailing a check, or depositing cash at a branch if the bank has physical locations.
Opening online versus at a branch
Opening online is faster and works if both account holders can access the bank's website at the same time or in sequence. One person starts the application, enters both names and Social Security numbers, uploads both IDs, and then the second person logs in to review and electronically sign the agreement. Some banks require both people to sign within a certain time window (usually 24 to 48 hours). The account typically opens within one business day after both signatures are collected.
Opening at a branch requires both people to visit the bank in person on the same day. A banker will verify both IDs, collect both signatures on the account agreement, and process the initial deposit. The account usually opens the same day or the next business day. This route is slower but eliminates any confusion about who signed what, and some people prefer it for joint accounts involving family members or partners.
Online banks have no branches, so they only offer online opening. Traditional banks (Chase, Bank of America, Wells Fargo) and credit unions offer both options. If you choose an online bank, both account holders need email addresses and access to a computer or phone to complete the process.
How joint account ownership works
In a joint account, both people own 100% of the money. Either account holder can withdraw all the funds without asking permission or notifying the other person. This is different from a power of attorney or authorized user arrangement, where one person controls the account on behalf of another. In a joint account, both people have equal legal rights to the money.
Both account holders receive statements and can see all transactions. Most banks send statements to one address by default, but you can usually request that statements be mailed to both addresses or that both people receive email alerts for every transaction. Setting up alerts is useful if you want to catch unauthorized withdrawals quickly.
If one account holder dies, the surviving account holder retains full access to the account and all funds in it. The money does not go through probate or require a court order. This is one reason couples and family members open joint accounts—it ensures the surviving person can access money immediately without legal delays. However, the account may be frozen temporarily while the bank verifies the death, usually for a few days to a week.
Minimum balance and APY requirements
Most high yield savings accounts do not require a minimum balance to open the account, but some do require a minimum balance to earn the advertised APY. For example, a bank might offer 4.50% APY on balances of $25,000 or more, and 4.25% APY on balances below that. If your balance drops below the minimum, you'll earn the lower rate until you bring it back up.
A few banks have no minimum balance requirement at all and pay the same APY on any balance, even $1. These are typically online banks. Traditional banks and credit unions are more likely to have minimums. Check the bank's website or call before opening to confirm whether a minimum applies and what rate you'll earn on your expected balance.
The APY on a joint account is identical to the APY on an individual account at the same bank. The bank does not charge a higher fee or pay a lower rate because two people own the account. The only difference is that both people can access the money.
Fees and account maintenance
Most high yield savings accounts have no monthly maintenance fee, whether the account is joint or individual. However, some banks charge a fee if your balance falls below a minimum (often $500 to $2,500) or if you make too many withdrawals in a month. Federal law allows up to six withdrawals per month from a savings account; some banks charge $10 to $25 for each withdrawal beyond that.
Joint accounts do not cost extra to maintain. You pay the same fees as you would on an individual account. If the bank charges a monthly fee, it applies to the joint account just as it would to a single-owner account.
Check the bank's fee schedule before opening. Most online banks publish their fees on their website under "Pricing" or "Fees." If you cannot find the information, call the bank's customer service line and ask specifically about monthly maintenance fees, withdrawal limits, and any fees for falling below a minimum balance.
Frequently Asked Questions
Can I open a joint account if one person lives in a different state?
Yes. If you're opening online, both people can sign electronically from anywhere. If you're opening at a branch, one person can go to the bank in person and the other can sign electronically, or both can open the account online without visiting a branch. Some banks require both people to be present at a branch, so ask before you start the process.
What happens if one account holder wants to close the account?
Either account holder can close a joint account without permission from the other person. When you close the account, the bank sends the remaining balance to the address on file or to one of the account holders' addresses. If both people want the money split differently, you'll need to withdraw it yourselves and divide it before closing.
Do I need to be married to open a joint account?
No. You can open a joint account with a spouse, partner, family member, friend, or business partner. The bank does not require a marriage certificate or any proof of relationship. You only need both people's IDs and Social Security numbers.
Will opening a joint account affect my credit score?
No. Opening a savings account does not affect your credit score. The bank may do a soft credit check (which does not show up on your credit report), but it will not lower your score. A hard credit check, which does affect your score, is only used when you apply for credit like a loan or credit card.
Can I remove one person from a joint account later?
Yes, but it depends on the bank. Some banks allow you to convert a joint account to a single-owner account by removing one person's name. Others require you to close the joint account and open a new individual account. Contact your bank to ask about their process; it usually takes a few business days and requires the signature of the person being removed.
