Yes, but the bank needs to know whose money it is
You can deposit cash into someone else's bank account, but you cannot hand the money to a teller and say "put this in their account." Banks require the account holder to be present, or they need written permission and proof of who you are. The reason is anti-money-laundering law: banks must know where cash is coming from and who is moving it. A deposit that appears to come from nowhere raises flags.
The simplest route is to have the account holder go to the bank with you. Both of you show ID, you hand over the cash, and the teller deposits it into their account while you are both there. This takes 10 minutes and requires no paperwork beyond what the teller asks for.
If the account holder cannot go to the bank, you have three other options: a power of attorney, a third-party deposit, or sending the money through a payment app. Each has different rules depending on the bank and the amount.
Key Takeaways
- The account holder must be present at the bank, or you need written permission from them and a valid ID to make the deposit.
- Banks report cash deposits over $10,000 to the federal government as a matter of routine, and deposits that look structured to avoid this threshold can trigger investigation.
- A power of attorney document lets you deposit money into someone's account without them being present, but it must be signed by the account holder and notarized.
- Payment apps like Venmo, PayPal, and Cash App let you send money to someone's phone number or email, and they can withdraw it or transfer it to their bank account.
- Some banks allow third-party deposits for family members or named beneficiaries, but policies vary widely — call your bank first.
Depositing cash when the account holder is present
This is the fastest and cleanest method. Walk into the bank together during business hours, go to a teller, and tell them you want to deposit cash into the account holder's account. Bring the account holder's ID and your own ID. The teller will ask a few questions: whose account, how much, and whether the account holder is depositing their own money or receiving it from you. Answer honestly.
The teller will fill out a deposit slip (or do it electronically), count the cash, and put it into the account. The money is usually available the same day for accounts at the same bank, or within one to two business days if it is a different bank. No forms to sign, no waiting period.
Using a power of attorney to deposit on someone's behalf
A power of attorney is a legal document that gives you the right to act on someone else's financial matters. If you have one, you can walk into the bank alone and deposit cash into their account without them being present. The account holder must sign the power of attorney document, and it usually needs to be notarized (a notary public witnesses the signature and stamps it). The cost is typically $50 to $150 for notarization.
Not all banks accept powers of attorney for deposits. Some require their own form, signed by the account holder. Call the bank ahead of time and ask what they need. Bring the original power of attorney document, your ID, and the cash. The teller will make a copy of the power of attorney for their records.
A power of attorney is overkill if you only need to deposit cash once. It makes sense if you are regularly handling someone's finances—for example, if you are managing money for an aging parent or a family member who is ill.
Third-party deposits and bank-specific rules
Some banks allow a third party (someone other than the account holder) to deposit cash without a power of attorney, but the rules are not standard. Wells Fargo, for example, allows third-party cash deposits for family members in some cases. Chase does not allow them at all. Bank of America requires the account holder to be present or to have signed a specific authorization form.
The only way to know what your bank allows is to call them or visit a branch and ask. Have the account number ready. Tell them you want to deposit cash on behalf of someone else and ask what documents or permissions they need. Write down the name of the person you spoke to and the date, in case you need to reference the conversation later.
If the bank says no, do not try to work around it. Tellers are trained to refuse deposits that do not follow the bank's rules, and pushing back will only delay the transaction.
Sending money through payment apps instead of the bank
If the account holder cannot go to the bank and the bank will not accept a third-party deposit, you can send the money through a payment app like Venmo, PayPal, Cash App, or Zelle. You transfer money from your bank account or debit card to their account in the app, and they can withdraw it to their bank account or spend it from the app balance.
This method works for any amount up to the app's daily limit (usually $500 to $2,000 per day, depending on the app and your account history). The money moves within minutes to a few hours. The account holder does not need to be present, and you do not need a power of attorney.
The trade-off is that payment apps are less formal than a bank deposit. If there is a dispute later about whether the money was a gift or a loan, the app record is thinner than a bank deposit slip. For small amounts or regular family transfers, this is not a problem. For large sums or money you expect to be repaid, a bank deposit creates a clearer paper trail.
Cash deposits over $10,000 and reporting requirements
Banks are required by federal law to report any cash deposit over $10,000 to the Financial Crimes Enforcement Network (FinCEN). This is not a problem if the money is legitimate—the report is routine and does not trigger an investigation by itself. The account holder will not be accused of anything just because a large deposit was reported.
What can trigger investigation is a pattern of deposits designed to stay under $10,000. If you deposit $9,500 one day, $9,500 the next day, and $9,500 the day after that, the bank will flag this as "structuring" and report it to the government. Structuring is illegal even if the money itself is legal. If you need to deposit a large sum, deposit it all at once and let the bank file the report.
Be honest about where the money came from. If the account holder asks you to say it is a gift when it is actually a loan, or to say it is from a job when it is from somewhere else, do not do it. The account holder is the one who will face consequences if the deposit is investigated and the story does not match the facts.
What to do if the bank refuses the deposit
If a teller refuses to take a cash deposit into someone else's account and you believe they are wrong, ask to speak to the branch manager. Explain the situation: you have the account holder's permission, you have ID, and you want to deposit cash. The manager can override the teller's decision or explain the bank's policy in detail.
If the manager still says no, ask for the policy in writing. Request the bank's customer service number and file a complaint if you believe the bank is breaking its own rules. You can also switch banks—if your current bank will not let you deposit cash on behalf of a family member, another bank might.
For very large deposits or unusual situations, call the bank's customer service line before you go in. Explain what you want to do and ask what documents or permissions you need. This saves a trip and prevents the teller from turning you away.
Frequently Asked Questions
Can I deposit cash into someone's account if they are not my family?
Yes, the bank does not care about your relationship to the account holder. You can deposit cash into a friend's account, a coworker's account, or a stranger's account. The bank only cares that you have permission from the account holder and valid ID. If the account holder is present, it is straightforward. If they are not present, you will need a power of attorney or the bank's written permission.
What if I want to deposit cash but the account holder does not want to go to the bank?
Ask the account holder to sign a power of attorney document and have it notarized. This gives you legal permission to deposit money on their behalf. Alternatively, use a payment app: you send money from your account to theirs, and they withdraw it to their bank account later. This is faster and does not require paperwork.
Do I need to tell the bank why I am depositing cash into someone else's account?
The teller will ask whose account it is and whether the money is a gift or payment for something. Answer honestly. You do not need to provide a detailed explanation, but do not lie about the source or purpose of the money. If the bank suspects something is wrong, they will ask more questions.
Will depositing cash into someone's account affect their taxes or benefits?
A cash deposit into a bank account is not automatically reported to the IRS or to benefit programs like Social Security or SNAP. However, if the account holder receives means-tested benefits (benefits based on income or assets), a large deposit could affect their may be able to access. If this is a concern, talk to the account holder or their benefits caseworker before making the deposit.
Can I deposit cash into a joint account without the other account holder's permission?
Yes. If you are a signer on a joint account, you can deposit cash into it without permission from the other account holder. Both of you own the account equally, so either of you can add money. However, both of you can also withdraw money, so be clear about whether the deposit is meant to be shared or set aside for one person's use.
