Yes, you can deposit cash into someone else's account, but the bank needs to know who you are

You can walk into a bank and deposit cash into another person's account if you have their account number and routing number. The bank will accept the deposit and credit it to their account. However, the bank will ask for your ID and may ask why you are depositing money into someone else's account. Some banks require the account holder to be present or to have authorized the deposit in advance.

The rules vary by bank. A few banks allow third-party cash deposits with no questions. Others require written authorization from the account holder, a notarized letter, or a power of attorney document. Some banks have stopped accepting third-party cash deposits altogether because of fraud and money-laundering concerns. Call the bank before you go in so you know what they need.

Key Takeaways

  • Most banks will accept a cash deposit into someone else's account if you provide their account number, routing number, and a valid ID.
  • The bank may require written authorization from the account holder or may ask you to explain the reason for the deposit.
  • Some banks have restrictions or have stopped accepting third-party cash deposits; call ahead to confirm your bank's policy.
  • If the account holder is present with you, the deposit is usually faster and requires fewer questions.
  • If the bank refuses, you can use a money order or cashier's check made out to the account holder instead.

What the bank will ask for when you arrive

Bring a valid government-issued ID—a driver's license, passport, or state ID card. The teller will write down your name, address, and ID number. They will also need the account holder's full name and account number. Have the routing number ready too, though the teller can usually look it up if you know the bank name and branch.

Be prepared to answer why you are making the deposit. Common answers—paying back a loan, sending money to a family member, splitting rent—are routine and usually require no proof. If the amount is large (typically $3,000 or more, though this varies by bank), the bank may file a Currency Transaction Report, which is a standard federal form. This is not a problem unless the deposit looks suspicious, such as multiple deposits just under the reporting threshold on the same day.

When the account holder needs to authorize the deposit

Some banks require the account holder to call ahead or visit the branch to authorize a third-party deposit. Others ask for a signed letter from the account holder stating that they consent to you depositing cash on their behalf. A few banks require a notarized authorization letter, which means the account holder must sign it in front of a notary public (available at banks, UPS stores, and some law offices).

If the account holder is present with you at the bank, authorization is usually not needed—the teller can see that both of you are there and willing. This is the fastest route if the account holder can make the trip.

Banks that have stopped accepting third-party cash deposits

Some large banks, including Wells Fargo and Bank of America, have restricted or eliminated third-party cash deposits at many branches. They cite fraud and money-laundering risk as reasons. If your bank has this policy, they will tell you when you call. Do not assume all branches follow the same rule; call the specific branch where you plan to deposit.

If your bank refuses, you have other options. A money order made out to the account holder can be deposited by them or by you if they authorize it. A cashier's check works the same way. Both are safer than cash because they leave a paper trail and cannot be spent by someone who finds them.

Depositing cash for someone who is not present

If the account holder is not with you, the bank needs proof that they want the money in their account. This is where authorization becomes important. A text message or email from them is not enough. The bank wants a signed letter or a phone call they can document.

Some banks will let you call the account holder while you are at the teller window so the teller can hear them consent. Others will not. Ask the teller what they can accept before you make the deposit attempt. If the account holder is out of state or out of the country, a notarized letter may be your only option.

What happens if the bank refuses your deposit

If the teller says no, ask why. If it is a policy issue, ask if another branch accepts third-party cash deposits or if a manager can make an exception. If the bank has a blanket ban, move to an alternative method.

A money order is the most straightforward backup. You buy it at a bank, post office, grocery store, or convenience store for a small fee (usually $1 to $5). Write the account holder's name on the "pay to the order of" line. They can deposit it themselves, or you can deposit it on their behalf if the bank allows third-party money order deposits (which is more common than third-party cash deposits).

Deposits over $10,000 and federal reporting

If you deposit $10,000 or more in cash on a single day, the bank must file a Currency Transaction Report with the federal government. This is automatic and legal. You do not need to do anything. The report does not flag you as suspicious unless the pattern of deposits looks deliberate—for example, depositing $9,999 ten times in one week to avoid the threshold.

If you are depositing money for someone else and the total reaches $10,000, the bank will still file the report. This is normal. The account holder will not be penalized for receiving a large deposit. However, if the bank suspects the deposit is part of money laundering or other illegal activity, they may refuse the deposit or file a Suspicious Activity Report in addition to the Currency Transaction Report.

Frequently Asked Questions

Can I deposit cash into someone else's account without them knowing?

Legally, yes—you can deposit cash into an account if you have the account number. However, the account holder will see the deposit on their statement. Some banks require the account holder to authorize the deposit in advance, so you may not be able to complete it without their knowledge or consent.

What if I want to deposit cash for my spouse or child?

If you are married and have a joint account, you can deposit into it freely. If the account is in their name only, the rules are the same as for any third party: bring ID, have the account number, and be ready to answer why. Many banks are more lenient with family members, but call ahead to confirm.

Do I need a receipt when I deposit cash into someone else's account?

Yes. Ask the teller for a deposit receipt. It shows the amount, the account number, the date, and the teller's name. Keep it until the account holder confirms the deposit appeared in their account, which usually takes one business day.

What if the account holder is deceased?

You cannot deposit into a deceased person's account. The bank will freeze the account once they learn of the death. If you need to settle the person's finances, work with their estate executor or attorney.

Can I deposit a check into someone else's account the same way?

No. Checks require the payee's endorsement. If a check is made out to someone else, they must sign the back and either deposit it themselves or sign it over to you with their signature and "pay to the order of [your name]." Cash deposits do not have this requirement, which is why the rules are different.
