You can add almost anyone, but the bank decides based on their rules and your account type

Most banks let you add a spouse, adult child, parent, or trusted friend to your checking or savings account. The person you add becomes a joint account holder with the same access to the money and account decisions as you have. But banks have different rules about who qualifies, what documents they need, and whether they'll allow it on certain account types like money market accounts or CDs. Some banks won't add anyone to accounts opened online, and a few won't add people who aren't related to you. The only way to know what your bank allows is to ask them directly — call the number on your card or visit a branch.

When you add someone, they gain equal legal ownership of every dollar in the account, even if you deposited all of it. This is different from giving someone power of attorney or naming them as a beneficiary. Those tools serve different purposes and give different levels of access. Understanding the difference before you act matters, because removing a joint holder later can be difficult or impossible without their agreement.

Key Takeaways

  • Joint account holders have equal legal rights to all the money in the account, even if one person deposited it all.
  • Banks require the person you're adding to provide a government ID, Social Security number, and sometimes proof of address.
  • Some account types — like certain savings products or accounts opened online — may not allow you to add joint holders.
  • Adding someone to your account is different from giving them power of attorney or making them a beneficiary, and each serves a different purpose.
  • If you want to remove someone later, both account holders usually have to agree, though some banks allow the original owner to remove them unilaterally.

What documents the bank will ask for

When you go to add someone to your account, bring both people's government-issued IDs — a driver's license, passport, or state ID card. The bank will also need the other person's Social Security number or tax ID number. Some banks ask for proof of address, usually a recent utility bill or lease in the person's name, though they may accept a bank statement or government document instead.

If you're adding someone who doesn't have a Social Security number — a non-citizen without an ITIN, for example — ask your bank whether they can use an alternative ID number. Some banks will, some won't. A few large banks have stopped accepting ITINs altogether, so this is worth confirming before you make the trip. The bank will also verify that the person you're adding is who they say they are by checking their ID against their name and date of birth. If the person has a common name or a history of fraud, the bank may do a more thorough background check, which can add a few days to the process.

Account types that may not allow joint holders

Most checking and savings accounts can have joint holders, but some specialty accounts cannot. Money market accounts, certificates of deposit (CDs), and individual retirement accounts (IRAs) often have restrictions. A traditional IRA, for example, can only have one owner — you cannot add a joint holder to it, though you can name a beneficiary who inherits it when you die.

If you opened your account online and never visited a branch, some banks won't let you add a joint holder without coming in person. This is because the bank wants to verify both people's identities face-to-face. A few online-only banks don't offer joint accounts at all, so check your bank's website or call before you assume it's possible. Business accounts, trust accounts, and accounts held in a minor's name have their own rules. If you're trying to add someone to any of these, ask your bank what's allowed — the answer depends on the account structure and your state's laws.

How long it takes and what happens next

Adding a joint holder usually takes one to five business days if you do it in person at a branch. The bank will update your account paperwork, issue new debit cards if needed, and send confirmation to both account holders. If you do it by mail or phone, it may take longer — up to two weeks — because the bank needs to verify signatures and identities without seeing you face-to-face.

Once the person is added, they have immediate access to the account. They can withdraw money, make deposits, set up automatic payments, and change account settings. They can also see all past transactions and balances. There is no "limited access" option on a joint account — either someone is a full holder or they are not. The bank will send account statements and tax documents (like 1099 forms) to the address on file, usually yours. If you want statements sent to both addresses, ask the bank to add a second mailing address to the account.

Joint accounts versus power of attorney and beneficiaries

Adding someone as a joint holder is not the same as giving them power of attorney or naming them as a beneficiary, and each one does something different. A joint account holder owns the money with you right now and can use it whenever they want. A power of attorney is a legal document that lets someone manage your account on your behalf, but they do not own the money — you do. A beneficiary inherits the account when you die, but has no access to it while you're alive.

If you want someone to help you pay bills but you don't want them to have full control, power of attorney might be better than a joint account. If you want to make sure your money goes to a specific person after you die without going through probate, a beneficiary designation is the right choice. If you want someone to have equal access and ownership right now, a joint account is what you need. Each option has different tax and legal consequences, so think through what you actually want the person to be able to do before you choose.

What happens if you want to remove someone later

Removing a joint holder is harder than adding one. At most banks, both account holders have to agree to the removal, and both have to sign paperwork in person or by notarized letter. This means if you add someone and later want them off, you may not be able to do it without their cooperation.

A few banks allow the original account owner to remove a joint holder unilaterally, but this is rare. Before you add someone, ask your bank what the removal process looks like — it's worth knowing the answer before you need it. If removal requires both people's consent and you later have a conflict with that person, you may have to close the account and open a new one, which can be complicated if direct deposits or automatic payments are tied to it. If the joint holder dies, the account usually stays open and the surviving holder keeps full access. The bank may ask for a death certificate, but they typically do not freeze the account or require probate.

What to watch out for with joint accounts

Joint account holders have equal legal claim to all the money, regardless of who put it there. If you deposit $50,000 and the joint holder deposits $100, they still own half of the $50,100. This matters if you're adding someone temporarily to help with bills, or if you're adding an adult child to help manage your finances in retirement. The money is theirs to take, and the bank cannot stop them.

Joint accounts also affect creditors and taxes. If the joint holder has unpaid debts, a creditor can sometimes go after money in the joint account to collect. If you're both earning income and the account earns interest, you may both owe taxes on that interest depending on how much each person contributed. Talk to a tax professional or accountant if you're adding someone and you're concerned about tax implications. Joint accounts also show up on both people's credit reports if the bank reports account activity to the credit bureaus. This is rare for checking accounts but more common for savings accounts and credit products. If you're adding someone with poor credit, it should not affect your credit score, but it's worth asking the bank whether they report joint account activity.

Frequently Asked Questions

Can I add someone to my account without them being present?

Most banks require both people to be present in person, especially if you're doing it for the first time. Some banks allow you to add someone by mail if you both sign and notarize the paperwork, but this takes longer — usually two to three weeks. Call your bank to ask whether they offer a mail option.

What if the person I want to add doesn't have a Social Security number?

Some banks accept an Individual Taxpayer Identification Number (ITIN) instead, but not all. A few large banks have stopped accepting ITINs entirely. Call your bank and ask whether they can add someone with an ITIN, or whether they need a different form of ID. If your bank won't do it, you may need to switch banks or use a credit union, which sometimes has different rules.

Can I add a minor to my account?

Most banks allow you to add a minor as a joint holder, but they usually require a parent or guardian to co-sign. Some banks have a minimum age — often 13 or 16 — before a minor can be on a joint account. A few banks offer custodial accounts instead, which are designed for minors and give the parent more control. Ask your bank what options they have for accounts with minors.

Does adding someone to my account affect their credit score?

No, adding someone as a joint holder should not affect their credit score. Joint checking and savings accounts are usually not reported to credit bureaus. However, if the account is a credit product like a joint credit card, it will show up on both people's credit reports.

Can I add someone to a savings account or CD?

Most banks allow joint holders on savings accounts, but CDs and money market accounts have stricter rules. Some banks do not allow joint holders on CDs at all, while others do but require both holders to agree before the CD matures. Ask your bank about the specific account type you have.
