To change your bank, you must be logged in from a web browser. Go to your name at the top right, choose "Settings" and then select the "Bank Accounts" tab.
Please note that we do not recommend linking a savings account to your Betterment account. This is because savings accounts typically limit the number of monthly withdrawals you can make. Please also note that some banks use the same account/routing number for checking and savings accounts, and in this situation our systems default to withdrawing from and depositing to your checking account.
Customers can only have one active checking account at a time linked to their Betterment account. Changing a bank account will replace the currently linked account and can interfere with and delay any incomplete transfers to and from the previously linked account, so we strongly recommend waiting for any pending transfers to complete before changing your bank account.
Because electronic transfer is the primary way to move money to and from your Betterment account, you will not be able to delete the link to your checking account unless you add a new one.
