Joint Bank Accounts: How and When They Work

Joint bank accounts belong to multiple people, each of whom can contribute to and use the money in the account. Such accounts can be a good fit for couples, adults assisting their aging parents and parents who are teaching their kids about money management.

On paper — and in an ideal world — joint accounts provide easy collaboration for spending and saving. But realistically, they require more self-awareness and trust than the typical bank account.

Here's a closer look at what to consider before opening a joint account.

Is a joint bank account a good idea?

A joint bank account can be a good idea as long as you and the other account holder have a strong, trusting relationship. Whether you’re planning to share an account with a child, significant other or aging parent, communication is essential. That may mean having difficult discussions about spending and saving habits. As uncomfortable as it may be, initiating these types of conversations can prevent even bigger headaches later.

Pros of joint bank accounts

• Parents can monitor a child’s spending habits and can quickly transfer money to a joint account when necessary.

• Couples can use a joint account to cover shared expenses such as rent, utilities and food, as well as shared savings goals, such as setting aside money for a vacation. Joint accounts can be helpful for married couples who are combining assets as well.

• Adult children can help aging parents manage their finances.

• A joint account can be set up so that if a parent dies, an adult child has immediate access to funds in the account, avoiding a potentially lengthy legal process.

• Federal insurance covers $250,000 per co-owner, so the total coverage for the account is $500,000. (Learn more about FDIC insurance.)

Cons of joint bank accounts

• A child may spend too freely and become overly reliant on mom or dad refilling the account.

• Co-owners on the account are both responsible for fees, such as overdraft charges.

• If one holder lets debts go unpaid, creditors can go after money in the joint account.

• Both holders can see transactions in the account, which can present privacy issues.

Joint bank accounts and marriage

Joint bank accounts are a common consideration for married couples who have legally combined their assets. Some couples may find it valuable to open a joint account even before the wedding so they can use it to pay for the event. Couples who live together before marriage may also find a joint account useful for paying for household expenses.

If you’re married — especially newly married — talk to your spouse about whether and how they’d like to set up a joint account with you. If you do decide to open a joint account, keep in mind that you don’t have to combine all of your money with your spouse’s. Some married couples share a joint account while also maintaining separate personal accounts, even if they only use those accounts as “fun money.”

How to open a joint bank account

Before you open an account, make sure you know the rules on your joint account, including who is allowed to close it. According to the Consumer Financial Protection Bureau website, “In most circumstances, either person on a joint checking account can withdraw money from and close the account.”

Setting up a joint bank account is much like opening a personal one. Here's what the process typically looks like:

• Select the "joint account" option during the application process with your bank.

• Provide the bank or credit union with personal information for all account holders, such as addresses, dates of birth and Social Security numbers.

If you’re opening a joint account with a significant other, you don't necessarily need to close your individual account. You may want to have money of your own for personal expenses or for gifts and surprises.
