The fastest way to deposit cash depends on your account type and location
Capital One offers three main routes to deposit cash: at a Capital One branch in person, through a Capital One ATM that accepts deposits, or by using a mobile check deposit if you have a paper check instead. Not all Capital One locations accept cash deposits at the counter, and not all ATMs are equipped to take cash—so your first step is confirming which method works where you bank.
If you have a Capital One 360 account (the online-only product), you cannot deposit cash directly with Capital One. You will need to deposit at your own bank first, then transfer the money to Capital One 360, or use a third-party service like MoneyLion or Alliant Credit Union if you are a member.
For traditional Capital One checking accounts held at a physical branch location, cash deposits at the teller window are the most straightforward option and typically post to your account the same day or next business day.
Key Takeaways
- Capital One branches accept cash deposits at the teller window during business hours, and the money usually posts the same day or next business day.
- Some Capital One ATMs accept cash deposits, but not all machines have this feature—check the screen or call ahead to confirm before you visit.
- Capital One 360 (online-only accounts) do not accept cash deposits directly; you must use another bank or a third-party service first.
- Bring your debit card or account number when depositing cash to ensure the money goes to the correct account.
- Weekend and holiday deposits may not post until the next business day, even if you deposit at an ATM.
Depositing cash at a Capital One branch
Walk into any Capital One branch during business hours with your cash and your debit card or account number. Tell the teller you want to deposit cash into your checking account. The teller will count the cash, enter the deposit into the system, and give you a receipt showing the amount and your account number.
The deposit typically posts the same day if you deposit before the branch's cutoff time (usually 2 p.m. or 3 p.m., but varies by location). Deposits made after cutoff or on weekends and holidays will post the next business day. There is no fee for depositing cash at a Capital One branch.
If you do not have your debit card, bring a government-issued ID and your account number. If you do not know your account number, call Capital One customer service at 1-800-869-3557 before you go, or ask the teller to look it up using your ID and Social Security number.
Using a Capital One ATM to deposit cash
Not every Capital One ATM accepts cash deposits. Before you visit, check the machine itself—the screen will show which services are available, or you can call the branch to ask whether that specific ATM takes deposits. If the machine does accept cash, insert your debit card, select "Deposit," choose "Cash," and follow the on-screen prompts.
The ATM will ask you to insert your bills one at a time. It counts them and displays the total on the screen. Review the amount, confirm it is correct, and the machine will accept the deposit. You will receive a receipt with the deposit amount and your account number.
ATM deposits typically post within one business day, though weekend and holiday deposits may take longer. There is no fee for using a Capital One ATM to deposit cash into your own account. If the machine rejects a bill or malfunctions, contact Capital One customer service immediately with your receipt and the time of the attempted deposit.
What to do if you have a Capital One 360 account
Capital One 360 is an online-only checking account with no physical branches. You cannot deposit cash directly into a Capital One 360 account. Instead, deposit the cash at your primary bank (the bank where you also hold a checking account), then transfer the money electronically to Capital One 360 using the account and routing numbers Capital One provides.
If you do not have another bank account, you can use a service like MoneyLion (which offers cash deposits at participating retailers) or join a credit union like Alliant that allows non-members to deposit cash at certain locations. Some Walmart and CVS locations also offer cash deposit services for a fee through third-party networks—ask at the customer service desk whether they accept deposits to online banks.
The transfer from your primary bank to Capital One 360 usually takes one to three business days, depending on your bank's processing speed. Plan ahead if you need the cash urgently.
Deposits that are rejected or delayed
Capital One ATMs may reject bills that are torn, stained, or worn. If this happens, try depositing at a branch teller instead, who can manually verify the bill and accept it if it is genuine. Keep your receipt from the failed ATM deposit attempt—it shows the time and amount, which helps Capital One investigate if the money does not appear in your account.
If you deposited cash and it has not appeared in your account after two business days, contact Capital One customer service at 1-800-869-3557. Have your receipt ready and be prepared to describe exactly when and where you made the deposit. Capital One will investigate and either locate the deposit or reverse any ATM fees if the machine malfunctioned.
Large cash deposits (typically $10,000 or more) trigger a federal reporting requirement called a Currency Transaction Report. This is routine and does not mean you have done anything wrong—Capital One is required by law to file it. The deposit will still post normally, but the filing may take a few extra days.
Timing and cutoff times for cash deposits
Capital One branch cutoff times vary by location, but most branches stop processing deposits at 2 p.m. or 3 p.m. on weekdays. Deposits made after cutoff will post the next business day. On Saturdays, Sundays, and federal holidays, Capital One branches are closed, so any ATM deposits made during these times will post on the next business day.
If you need the cash to be available urgently, deposit at a branch teller before cutoff on a weekday. ATM deposits are convenient but may take longer to post, especially if you deposit on a Friday afternoon or weekend.
Check your Capital One account online or through the mobile app to confirm when the deposit posted. The app shows pending deposits separately from posted deposits, so you can track the status in real time.
Frequently Asked Questions
Can I deposit cash into someone else's Capital One account?
No. You can only deposit cash into an account if your name is on it or you have power of attorney. If you want to give someone money, deposit it into your own account first, then transfer it to them electronically or give them cash directly.
What if the ATM keeps my cash and does not deposit it?
Contact Capital One customer service immediately with your receipt and the time of the deposit. Capital One will investigate the machine's records. If the machine did accept your cash, it will post to your account within one to two business days. If the machine malfunctioned and kept your money, Capital One will refund you after confirming the error with the ATM operator.
Is there a limit to how much cash I can deposit at once?
Capital One does not publish a daily deposit limit for cash. However, ATMs may have a physical limit (often $1,000 to $5,000 per transaction), and branch tellers may ask questions about very large deposits. If you are depositing more than $10,000, expect a Currency Transaction Report to be filed—this is normal and does not delay your deposit.
Do I need to tell Capital One I am depositing cash?
No. Simply deposit the cash at a branch or ATM, and it will post to your account. You do not need to call ahead or notify Capital One in advance unless you are depositing an unusually large amount and want to confirm the branch has enough teller availability.
Can I deposit cash through Capital One's mobile app?
No. The Capital One mobile app allows you to deposit checks by taking a photo, but not cash. For cash deposits, you must visit a branch or use a Capital One ATM in person.
