To delete a bank account, it must not have any accounting transaction in that bank account. Follow these steps to delete the bank account;

  1. Should you delete the bank account, go to Setting > Chart of Account.
  2. Select the checkbox at the Bank Account in Asset tab.
  3. Click Delete.

What if you don't see any checkbox at the bank account?

It means the bank account has accounting transactions and it cannot be deleted UNLESS you delete the accounting transactions associate with that bank account.
