What happens when you add someone to your account
When you add someone to your bank account, you give them legal access to the money in that account. They can withdraw funds, make deposits, write checks, use the debit card, and see the transaction history. The bank treats them as an owner of the account, not as someone you've given permission to help you. This is different from naming a power of attorney or a beneficiary — those arrangements give someone authority only under specific conditions or after you die.
The person you add becomes what the bank calls a joint account holder or authorized user, depending on how the account is set up. A joint account holder owns the account equally with you and has the same rights. An authorized user can access the account but may not own it — the rules vary by bank. Before you proceed, you need to know which one you're creating, because the legal and tax consequences are different.
Key Takeaways
- Joint account holders and authorized users have different legal rights; joint holders own the account equally, while authorized users only have access.
- You will need the other person present at the bank with a government-issued ID, or you can add them online if your bank offers that option.
- Adding someone to your account affects how the IRS treats income and gifts, and can expose the money to the other person's creditors or ex-spouse in a divorce.
- You can remove someone from an account at any time by going to the bank in person or calling, though some banks require both account holders to agree.
In-person versus online: which route your bank offers
Most banks let you add someone to an account in person at a branch. You and the other person both go to the bank together, bring government-issued photo IDs (a driver's license or passport), and tell the banker you want to add them as a joint holder or authorized user. The banker will have you both sign new account documents. This usually takes 15 to 30 minutes, and the change takes effect when ready or within one business day.
Some banks now let you add someone online through their mobile app or website. You enter the person's name, date of birth, and Social Security number, and the bank sends them a verification link via email or text. They confirm their identity, and the account is updated. This method is faster — sometimes within hours — but not all banks offer it yet. Call your bank's customer service line or log into your account to see if the option is available.
If you cannot go to the branch together, some banks will mail you forms to sign and return. This is slower and requires both of you to sign in front of a notary public in many cases. Ask your bank whether this option exists before you choose it; it can take two to four weeks.
What documents and information you need
Bring the other person's government-issued photo ID — a driver's license, passport, or state ID card. The bank will copy it or scan it. You will also need your own ID and your account number (on your debit card or a recent statement). If you are adding someone remotely, have their full legal name, date of birth, and Social Security number ready.
Some banks ask for additional information depending on the type of account. If it is a savings account with a minor, the bank may require proof of guardianship. If it is a business account, you may need to show business registration documents. Ask your bank in advance what you need to bring; most banks list this on their website or will tell you when you call.
Joint account holders versus authorized users: which one to choose
A joint account holder owns the account equally with you. If you die, the money passes to them automatically — it does not go through your will or probate. They can also be held responsible for overdrafts or fees on the account. If they are sued or file for bankruptcy, a creditor can potentially reach the money in the joint account. In a divorce, the account is usually considered marital property and split between spouses.
An authorized user can access the account and move money, but does not own it. If you die, the money does not automatically go to them — it stays part of your estate. Authorized users are generally not responsible for overdrafts or account fees. Creditors cannot reach the account through an authorized user's debt, and the account is not divided in a divorce. However, not all banks offer authorized user status on all account types; some banks only offer joint accounts.
If you are adding a spouse or adult child you trust completely and want the money to pass to them if you die, choose joint account holder. If you are adding someone to help you manage money but want to keep ownership and control, ask the bank whether authorized user status is available. If it is not, you may want to explore a power of attorney instead.
Tax and legal consequences of adding someone
The IRS treats money in a joint account as belonging to whoever deposited it, unless you can prove otherwise. If you put $50,000 into a joint account and the other person withdraws $20,000, the IRS does not assume you gave them a $20,000 gift. However, if you put money in and they withdraw it with no expectation of repayment, the IRS may view it as a gift. Gifts over a certain amount (which changes yearly) must be reported on a gift tax return, though most people do not owe tax on them.
If the other person owes money to creditors, a creditor can sometimes freeze or seize money in a joint account, even if you deposited all of it. If they are going through a divorce, their ex-spouse's lawyer can argue that the joint account is marital property. If they face a lawsuit, the plaintiff's attorney can try to reach the account. These are real risks, not theoretical ones.
Before you add someone, talk to a tax professional or attorney if you have significant assets or complicated finances. A few hundred dollars in legal information can prevent much larger problems later.
How to remove someone from an account
You can remove someone from a joint account by going to the bank in person, calling customer service, or using online banking if your bank offers that option. Bring your ID and your account number. The bank will ask you to confirm that you want to remove the other person, and the change usually takes effect when ready or within one business day.
Some banks require both account holders to agree to the removal. If that is the case with your bank and the other person refuses, you have limited options. You can close the account entirely and open a new one, but that means the other person can still access the money until the account is officially closed. If you believe the other person is misusing the account or you are in danger, contact your bank's fraud department or local law enforcement.
Removing someone does not affect their access to past statements or transaction history if they have already seen them. It only stops them from making new transactions going forward.
Frequently Asked Questions
Can I add someone to my account without telling them?
Legally, no. The person must consent and usually must be present or verify their identity. Banks require this to prevent fraud. If you add someone without their knowledge, they can contact the bank and remove themselves, and you could face legal consequences for unauthorized use of their identity.
What if the person I want to add does not have a Social Security number?
Banks require a Social Security number or Individual Taxpayer Identification Number (ITIN) to add someone to an account. If the person does not have one, they will need to obtain an ITIN from the IRS before the bank can proceed. This process takes several weeks.
Does adding someone to my account affect their credit score?
No. Adding someone as a joint account holder or authorized user does not appear on their credit report or affect their credit score. However, if the account goes into overdraft or is sent to collections, it can damage both of your credit scores.
Can I add someone to just part of my account balance?
No. When you add someone to an account, they have access to the entire balance, not a portion of it. If you want to give someone access to only some of your money, you would need to open a separate account and transfer that amount into it.
What happens to the account if the joint holder dies?
The money in the account passes to the surviving account holder automatically, outside of probate. This is called the right of survivorship. The bank will ask for a death certificate and will transfer ownership to you. If you both die at the same time, the account becomes part of both estates.
