Yes, you can open a joint bank account with anyone, married or not
Banks do not require marriage to open a joint account. You can add a spouse, partner, family member, business co-owner, or trusted friend to an account. The bank cares about identity verification and tax reporting, not your relationship status.
What matters to the bank is that both account holders can prove who they are, agree to the terms, and provide a Social Security number or tax ID for each person on the account. The IRS requires this for tax reporting purposes, not because of any relationship rule.
The main differences between married and unmarried joint accounts are legal, not banking. If you are married, your state's community property or marital property laws may affect what happens to the account if you divorce. If you are not married, those laws do not apply—but you still need to think through what happens if the relationship ends or one person dies.
Key Takeaways
- Banks allow joint accounts for any two people who can verify their identity and provide tax identification, regardless of marital status.
- Both account holders have equal access to all money in the account unless you set up restrictions with the bank.
- If one account holder dies, the money typically passes to the surviving account holder automatically if the account is set up as "joint with rights of survivorship"—but this does not happen automatically in all states or account types.
- Unmarried couples should discuss and document what happens to the account if the relationship ends, because state law will not divide it the way it would for married couples.
- You will need government-issued ID, a Social Security number or ITIN for each person, and proof of address for both account holders.
What you need to open a joint account
Both people must visit the bank in person or complete the process online, depending on the bank's rules. You will need a government-issued photo ID for each account holder—a driver's license, passport, or state ID card. The bank will verify your identity against their fraud database.
Each person must provide a Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN). The bank reports account activity to the IRS using these numbers. If either person does not have an SSN or ITIN, some banks will not open the account; others have workarounds, but they are rare.
You will also need proof of address—usually a recent utility bill, lease, or mortgage statement in one of your names. Some banks accept a bank statement or government document instead. The address does not have to be the same for both people.
How money and access work in a joint account
In a standard joint account, both people own all the money. Either account holder can withdraw, transfer, or spend the entire balance without permission from the other. There is no "your half" and "my half"—it is all accessible to both.
This is different from a savings account where you are just an authorized user. An authorized user can withdraw money but does not own the account; the account owner can remove them at any time. In a joint account, both people are owners with equal rights.
If you want to limit access, you can ask the bank about restrictions—for example, requiring both signatures to withdraw over a certain amount, or setting up alerts when money moves. Not all banks offer these options, and the ones that do may charge a fee. It is worth asking before you open the account.
What happens to a joint account if someone dies
This depends on how the account is titled. If it is set up as "joint with rights of survivorship" (sometimes called JTWROS), the surviving account holder automatically owns all the money when the other dies. The account does not go through probate, and the money is not part of the deceased person's estate.
If the account is titled as "joint tenants in common" (or just "joint"), the deceased person's share becomes part of their estate and goes through probate. Their share may go to their heirs or to whoever they named in their will, not automatically to the surviving account holder. This varies by state.
When you open the account, ask the bank which type of account they are setting up. Most banks default to rights of survivorship, but you should confirm. If you are not married and want the money to go to the other account holder, make sure the account is titled for survivorship.
Joint accounts and taxes
The bank reports interest earned on the account to both Social Security numbers. Each person receives a 1099-INT form showing their share of the interest. If the interest is small, this is straightforward. If the account earns significant interest, you may need to split it between you or decide who claims it on their tax return.
The IRS does not care whether you are married. What matters is that both people have SSNs on file and the bank reports correctly. If you do not sort out who claims what, you may both receive forms showing the full amount, which can create confusion at tax time.
Deposits to a joint account are not taxable income to either person—you are just moving money around. Withdrawals are not taxable either. Only interest, dividends, or other earnings on the account trigger tax reporting.
Risks of joint accounts for unmarried people
The biggest risk is that either person can take all the money at any time. If the relationship ends badly or one person has a financial crisis, they can empty the account without your permission. There is no legal recourse to get the money back unless you can prove fraud or theft, which is hard to prove when both people are authorized owners.
If one account holder has debt or legal judgments against them, a creditor can freeze or seize the joint account. The creditor may not care that the money belongs partly to the other person—they will go after the account first and make you prove your share later.
If one person dies without a will and the account is not set up for survivorship, the money may not go to the surviving account holder. It could go to the deceased person's parents, siblings, or other heirs depending on state law. This is why confirming the account type matters.
Alternatives to joint accounts
If you want to share money but protect yourself, consider a payable-on-death (POD) account. You own the account alone, but you name someone to receive the money if you die. They have no access while you are alive, and the account does not go through probate. This works well if you want to leave money to a partner or family member but keep control during your lifetime.
A power of attorney lets you give someone the right to manage your account without making them a joint owner. They can withdraw money and pay bills on your behalf, but they do not own the account. You can revoke the power of attorney at any time, and it ends automatically if you die.
For business purposes, some people use a business account with multiple signers instead of a personal joint account. This is more formal and may offer better liability protection, but it requires setting up a business structure first.
Frequently Asked Questions
Can I open a joint account online without going to the bank?
Some banks allow you to open a joint account online, but both people usually need to verify their identity through the bank's app or website. A few banks still require at least one person to visit in person. Check with your bank about their specific process before you start.
What if one person on the joint account has bad credit?
Bad credit does not prevent someone from being added to a joint account. Banks do not run a credit check for joint account holders the way they do for credit cards or loans. However, if one person has unpaid debts, a creditor can still go after the joint account.
Can I remove someone from a joint account?
Yes, but it depends on the bank. Most banks allow either account holder to remove the other, though some require both people to agree or require the person being removed to be present. Once someone is removed, they lose access to the account. Ask your bank about their removal process when you open the account.
Do I need to tell the other person before I withdraw money from a joint account?
No. Both account holders have equal rights to all the money. You do not need permission to withdraw, transfer, or spend. This is why joint accounts work best when both people trust each other completely.
What happens to a joint account if we break up?
The account does not automatically split. If you are married, divorce courts can divide it as part of the settlement. If you are not married, there is no legal process to divide it—you have to work it out between yourselves or take the other person to small claims court. The safest approach is to close the account and open separate ones as soon as the relationship ends.
