If you're serious about How to Delete Bank Account from Quickbooks Online account, here are the actions you'll need to take:

Note: If you've decided to remove an account from your COA (chart of accounts), it's a good idea to preserve a backup Excel file with all of your bank data and financial reports. If you decide to use QuickBooks again, getting that data back into the account becomes quite difficult. Also, keep the following in mind while deleting a bank account in QuickBooks:

• In QBO, the bank will be deactivated.
• If the account's balance isn't zero, we'll make an adjustment transaction.
• Although you can reactivate a deactivated account, you may need to correct journal entries and balances.

Step 1: To delete an account, first make it inactive.

Your bank account in QuickBooks will be deleted if you make it inactive. You must do so by following the steps outlined below:

• Select the Chart of Accounts from the Gear icon.
• Look for the account you wish to remove there.
• Finally, pick Make inactive from the Action drop-down menu.

Important: If you remove a bank account in QuickBooks that still has a balance, QuickBooks makes a journal entry that transfers the balance to another account. Existing transactions do not vanish and remain on your financial statements. If you decide to utilize the account again in the future, QuickBooks will not update the journal item or shift the balance back.

If you ever need to check your dormant accounts for whatever reason, simply follow the steps below.

Step 2: Examine Your Dormant Accounts

To see your dormant accounts, follow the steps below:

• Select Chart of Accounts from the Settings menu.
