Yes, someone else can deposit cash into your account, but the bank needs to know who they are
Another person can walk into your bank branch or use an ATM to deposit cash directly into your account. They do not need your permission beforehand, and they do not need to be on the account. The bank will ask for your account number (which they can get from you, a check, or a deposit slip) and will process the deposit the same way it processes any other cash deposit.
The deposit shows up in your account, and you can spend it immediately — though the bank may place a hold on large cash deposits while they verify the source. The person making the deposit does not get a receipt with your account details; they get a receipt showing only that they deposited cash to an account number.
Key Takeaways
- Anyone can deposit cash into your account at a branch or ATM using only your account number; they do not need your permission or to be listed on the account.
- The bank may hold large cash deposits (the threshold varies by bank and deposit size) while they verify where the money came from.
- The person depositing does not see your account details on their receipt, only confirmation that the deposit went through.
- Your bank may ask you questions about large or frequent cash deposits from the same person, especially if the pattern looks unusual.
- If someone deposits cash into your account without your knowledge, you can contact your bank to reverse it, though the process depends on timing and the bank's policies.
What information the other person needs to make the deposit
The depositor needs your account number and the name of your bank. They do not need your Social Security number, your PIN, your password, or permission from you. If they are depositing at a branch, they can provide the account number verbally or on a deposit slip. If they are using an ATM, they enter the account number on the screen.
Many people get the account number from a check, which prints it at the bottom. Others ask the account holder directly. Some banks print account numbers on deposit slips you can hand out. The account number alone does not let someone withdraw money or change your account settings — it only lets them add funds.
How banks handle large or frequent cash deposits
Banks are required to report cash deposits over $10,000 to the federal government using a form called a Currency Transaction Report (CTR). This is routine and does not mean anything is wrong. The bank files the report automatically; you do not have to do anything.
If the same person deposits cash into your account repeatedly, or if the deposits are large, your bank may contact you to ask where the money is coming from. This is called suspicious activity monitoring, and banks do it to prevent money laundering and fraud. You can simply explain — a family member sending money, a roommate paying rent, a friend repaying a loan — and the bank will note it in your file. If you do not respond or your explanation does not match the pattern, the bank may file a Suspicious Activity Report (SAR) with federal authorities, though this does not mean you have done anything illegal.
The threshold for questions varies by bank. Some banks ask about deposits over $5,000; others wait until the pattern becomes frequent or the amounts are very large. If you know someone will be depositing cash regularly into your account, telling your bank in advance can prevent delays or holds.
When the bank might hold the deposit
A deposit hold means the bank credits the money to your account but does not let you withdraw it immediately. Holds on cash deposits are less common than holds on checks, but they do happen — especially for large amounts, deposits made at an ATM rather than a branch, or deposits from someone the bank does not recognize.
The length of the hold depends on the bank and the circumstances. A hold on a cash deposit at a branch might last one business day. A hold on a large cash deposit at an ATM might last up to three business days. During the hold, the money shows in your account balance, but you cannot spend it. Once the hold lifts, the money is available.
If the hold is longer than you expected, call your bank and ask why. They may be verifying the source of the cash or following their own internal policies. You can ask them to lift the hold early if you need the money, though they are not required to do so.
What happens if someone deposits cash without your knowledge
If you discover that someone deposited cash into your account without your permission, contact your bank immediately. The bank can reverse the deposit and return the money to the person who made it — but only if you report it quickly and the deposit has not yet cleared or been withdrawn.
If the deposit has already cleared and you have spent the money, reversing it becomes more complicated. The bank may still reverse it, but you would then owe that money back to the bank. If you cannot repay it, your account could go negative, and the bank could pursue collection.
If you suspect the deposit is part of fraud — for example, someone is using your account to launder money or hide the source of funds — report it to your bank and to the Federal Trade Commission (FTC) at reportfraud.ftc.gov. Your bank can freeze the account while they investigate.
Depositing cash into someone else's account as a gift or loan
If you want to deposit cash into someone else's account, you can do so at their bank branch or at an ATM, provided you have their account number. You do not need their permission, though it is polite to tell them first so they are not surprised by the deposit.
If the deposit is a gift, there are no tax consequences for either of you — gifts are not taxable income. If it is a loan, consider putting the terms in writing (amount, repayment date, interest if any) so there is no confusion later. If the amount is large or you make frequent deposits, the recipient's bank may ask them questions about the source of the money, so let them know to expect that.
Frequently Asked Questions
Can someone deposit cash into my account if they do not know my full name?
Yes. The bank needs only your account number, not your name. The account number is enough to route the deposit to the correct account. However, if the person is depositing at a branch and the teller notices the name on the deposit slip does not match the account, they may ask for clarification — but this is rare.
What if I want to stop someone from depositing cash into my account?
You cannot prevent someone from depositing cash using only your account number. However, if someone is depositing money into your account without your permission and you want it to stop, contact your bank and explain the situation. The bank can flag the account and monitor for unauthorized deposits, and you can report the person to law enforcement if the deposits are part of fraud or theft.
Do I have to report cash deposits from family members?
You do not have to report gifts from family members to the IRS. However, if your bank asks where the money came from, you should answer honestly. Telling the bank "my mother sent me money" is a normal explanation and will not cause problems. The bank is not asking you to report it to the government; they are verifying that the deposit is legitimate.
Can someone deposit cash into my account at a different bank?
No. The person must deposit the cash at your bank or at an ATM owned by your bank. They cannot walk into a different bank and deposit cash into your account. If they want to send you money through a different bank, they would need to use a wire transfer, which requires your bank account details and routing number.
Will a cash deposit affect my credit score?
No. Deposits into your bank account do not affect your credit score. Your credit score is based on your borrowing and repayment history — loans, credit cards, and payment records. Bank deposits are not reported to credit bureaus.
