Bank account details can be updated directly from the Stripe Dashboard:
From the Stripe dashboard menu, click on the Settings icon and then under your Business settings, click on External Payout Accounts and Scheduling and scheduling.
Click on the Edit button next to the currently linked bank.
Provide the new bank account information.
Click Edit Account to update.
In some cases, you may be required to enter the previous bank account information as a security measure.
If your bank account information is updated while a payout is already in transit, that payout will be sent to your old bank account.
If you have any trouble updating your bank account information, such as having forgotten your previous bank account information, contact Stripe Support.
