Close your account online, by phone, or by mail — the fastest way is through your online dashboard

Capital One 360 lets you close your savings account through your online account, by calling their customer service line, or by sending a written request. The online method is fastest: you can initiate the closure in minutes and the account typically closes within one to three business days. If you prefer to speak with someone, call 1-877-383-4802. If you close by mail, send a signed letter requesting closure to Capital One 360's mailing address (listed on your account statements or website).

Before you close, make sure your account balance is zero or transfer any remaining funds to another bank account. Capital One will not close an account with a balance. If you have pending transactions or scheduled transfers, those may delay closure. Once closed, you will no longer be able to access the account, deposit funds, or use any debit card linked to it.

Key Takeaways

  • You must have a zero balance before Capital One will close your savings account — transfer or withdraw any remaining money first.
  • Online closure through your dashboard is the fastest method and typically completes within one to three business days.
  • If you close by phone, call 1-877-383-4802 and have your account number and identification ready.
  • Pending transactions or automatic transfers may delay closure, so cancel or complete these before requesting closure.
  • After closure, you will lose access to the account and any linked debit card immediately.

Steps to close online through your Capital One 360 dashboard

Log into your Capital One 360 account on the website or mobile app. Navigate to the account settings or account management section — this is usually found in a menu labeled "Settings," "Profile," or "Account." Look for an option that says "Close Account" or "Manage Accounts." Select your savings account from the list if you have multiple accounts.

Capital One will show you your current balance and ask you to confirm that it is zero. If it is not, you will need to go back and transfer or withdraw the remaining funds before you can proceed. Once you confirm a zero balance, you will be asked to provide a reason for closing (optional) and to review the closure terms. Click "Confirm" or "Close Account" to complete the request. You should receive a confirmation message on screen and via email.

Closing by phone with Capital One customer service

Call 1-877-383-4802 during business hours (typically 7 a.m. to 11 p.m. Eastern Time, seven days a week). Have your account number, Social Security number, and a form of identification ready. Tell the representative you want to close your savings account.

The representative will verify your identity, confirm your account balance is zero, and ask if you want to close the account. They may ask why you are closing — you do not have to provide a reason, but some customers find it helpful to share feedback. Once you confirm, the representative will process the closure and provide you with a confirmation number. Write down this number for your records.

Closing by mail with a written request

Write a letter on plain paper that includes your full name, account number, date of birth, and a clear statement that you want to close your savings account. Sign and date the letter. Include a copy of your government-issued ID (driver's license or passport) or a recent utility bill showing your name and address.

Mail the letter to the address listed on your account statements or the Capital One 360 website. Send it via certified mail with return receipt requested so you have proof of delivery. Capital One typically processes mail requests within five to ten business days after receiving them. Keep a copy of your letter and the certified mail receipt until you receive written confirmation that the account is closed.

What happens to your money before you close

You must move or withdraw all money from your savings account before Capital One will close it. You can transfer funds to another bank account you own at any financial institution — this typically takes one to three business days depending on the receiving bank. You can also withdraw cash at an ATM using your Capital One 360 debit card, or request a check from Capital One.

If you have direct deposits set up to this account, change the deposit destination to another account before closing. If you have automatic bill payments or transfers scheduled from this account, cancel or redirect them first. Any pending transactions that have not yet cleared may cause the closure to be delayed.

After your account closes

Once closed, you cannot reopen the same account. If you want to use Capital One 360 again in the future, you would need to open a new account. Your account history and statements will remain available through your online portal for a limited time — typically 90 days to one year depending on Capital One's policy. Download or save any statements you need before closure.

If you had a debit card linked to this account, it will stop working immediately after closure. If you have other Capital One 360 accounts (checking, money market, or other savings accounts), those will not be affected by closing one account. Capital One will not charge a fee to close your account.

Frequently Asked Questions

Can I reopen my Capital One 360 savings account after I close it?

No, you cannot reopen the same account once it is closed. If you want a Capital One 360 savings account in the future, you will need to open a new account. Your old account number will not be reactivated.

What if I have a pending deposit or transfer when I try to close?

Wait for the transaction to complete before requesting closure. Pending transactions can delay or block the closure process. Check your account activity to confirm all transfers and deposits have cleared, then initiate closure.

Will closing my Capital One 360 savings account affect my credit score?

Closing a savings account does not directly affect your credit score because savings accounts do not appear on your credit report. However, if you have a linked Capital One credit card, closing the savings account will not impact that card's status or your credit history.

How long does it take for Capital One to close my account after I request it?

Online closures typically complete within one to three business days. Phone closures may take one to five business days. Mail requests usually take five to ten business days after Capital One receives your letter. You will receive email confirmation once the closure is final.

What should I do with my debit card after I close the account?

Your debit card will stop working immediately after closure. You can destroy it by cutting it up, or you can contact Capital One to request they deactivate and send you a replacement if you have other active accounts with them.
