Yes, you can link a bank account to Cash App, and it takes about five minutes
Cash App lets you connect a checking or savings account so money can move between your bank and the app. You'll need your bank's routing number and your account number — both are on the bottom left of any check you have, or you can call your bank and ask. Cash App will verify the account by depositing two small amounts (usually under a dollar each) into it, then ask you to confirm those amounts in the app. Once verified, you can send money to other Cash App users, receive money from them, and move your own money back to your bank whenever you want.
The whole process from start to finish usually takes one to three business days, because that's how long the test deposits take to show up. After that, your account is ready to use when ready.
Key Takeaways
- You will need your bank account number and routing number, which appear on the bottom of your checks or are available by calling your bank.
- Cash App verifies new accounts by depositing two small test amounts and asking you to confirm them, a process that usually takes one to three business days.
- Once linked, your bank account becomes the source for sending money and the destination for receiving it back, but you can also keep money in your Cash App balance.
- You can link multiple bank accounts to the same Cash App, though only one can be set as your default for sending money.
- Linking a bank account is free, but Cash App charges a 3% fee when you send money using a credit card instead of a bank account or your Cash App balance.
The step-by-step process to link your bank account
Open Cash App and tap the profile icon in the bottom right corner. Select "Linked Bank Accounts" or "Add Bank Account" — the exact wording depends on whether you already have one linked. You'll be asked to enter your bank's name, your account number, and your routing number. If you don't know your routing number, call your bank's customer service line and ask for it; they can give it to you in under a minute.
After you enter this information, Cash App will send two deposits to your account, usually for amounts like $0.01 and $0.02. These deposits take one to three business days to show up. Once they appear in your bank account, go back to Cash App and enter the exact amounts you received. Cash App will then mark the account as verified, and you can start using it right away.
If you're linking a bank account for the first time, Cash App may also ask you to verify your identity by providing your full name, date of birth, and the last four digits of your Social Security number. This is a standard security step and does not mean anything is wrong with your account. You'll enter this information directly in the app.
What happens after your bank account is verified
Once your account is verified, Cash App will use it as your default source when you send money to other people. If someone sends you money, it goes into your Cash App balance first — a temporary holding area within the app. From there, you can spend it using your Cash App card (if you have one), send it to someone else, or transfer it back to your bank account.
Transferring money from Cash App back to your bank account is free if you choose the standard transfer, which takes one to three business days. Cash App also offers an when ready transfer option for a small fee, usually $0.25 to $1.50 depending on the amount. You decide which speed you want each time you transfer.
Linking multiple bank accounts and changing your default
You can link more than one bank account to Cash App. This is useful if you have accounts at different banks or want to keep personal and business money separate. To add another account, follow the same process: go to your profile, select "Linked Bank Accounts," and add a new one. Each account will go through the same two-deposit verification.
Only one account can be set as your default for sending money. If you have two accounts linked and want to switch which one Cash App uses when you send money, go to your profile, select "Linked Bank Accounts," and choose which account you want to be primary. You can also choose a different account for a single transaction without changing your default.
Why linking a bank account matters for fees
Cash App charges a 3% fee when you send money using a credit card, but charges nothing when you send from a bank account or your Cash App balance. This is a significant difference: sending $100 from a credit card costs $3, while sending the same amount from a linked bank account costs nothing. If you plan to send money regularly, linking a bank account saves you money.
Receiving money is always free, regardless of how the sender paid for it. The fee only applies to the person sending the money, not the person receiving it. This is why many people link a bank account even if they don't plan to send money often — it keeps their options open without extra cost.
Security and what to watch for
Cash App uses encryption to protect your account information, the same technology banks use. Your bank account number and routing number are not stored in a way that lets anyone else see them. However, you should still protect your Cash App password and never share it, just as you would with your bank password.
If you notice a deposit you don't recognize or suspect someone has accessed your account, contact Cash App support through the app when ready. Go to your profile, tap "Support," and describe what happened. Cash App can freeze your account while they investigate.
What to do if verification fails or takes too long
If the two test deposits don't appear after five business days, your bank may be blocking them. Some banks flag small deposits from unfamiliar sources as suspicious. Call your bank and ask if they received deposits from Cash App; if they did, ask the bank to allow them through. Then check Cash App again — the deposits should appear within a day.
If your bank says they never received the deposits, go back to Cash App and double-check that you entered your account number and routing number correctly. A single wrong digit will cause the deposits to go to the wrong account. Delete the account from Cash App and try again with the correct information.
If you're still having trouble after a second attempt, contact Cash App support. They can sometimes manually verify an account or troubleshoot what's happening with your bank.
Frequently Asked Questions
Can I link a savings account, or does it have to be checking?
You can link either a checking or savings account. Cash App works with both. The process is identical — you'll still receive the two test deposits and confirm them in the app.
What if I don't have checks and can't call my bank?
Log into your bank's website or mobile app and look for account details or account information. Your routing number and account number are usually listed there. If your bank's website doesn't show them, call the customer service number on the back of your debit card.
Do I have to keep money in Cash App, or can I transfer it all back to my bank?
You can transfer all of it back. There's no requirement to keep a balance in Cash App. Some people use it only to receive money and when ready move it to their bank account; others keep some money there for convenience. It's entirely your choice.
What happens if I unlink my bank account?
Unlinking stops Cash App from being able to pull money from that account for sending. Any money already in your Cash App balance stays there — it doesn't disappear. You can still receive money and spend your balance, but you won't be able to send money unless you link a different account or use your Cash App balance.
Can someone else link my bank account to their Cash App?
No. Cash App requires identity verification when you link an account, so someone would need your account number, routing number, and personal information like your date of birth and Social Security number. If you suspect someone has done this, contact Cash App support and your bank when ready.
