If you are using micro deposits to verify your bank, the entire process can take 5-6 business days to link your bank and transfer funds. After your Stash account is complete and verified, it takes 1-3 business days for micro deposits to appear in your linked bank account. Your next step is to confirm those micro deposits in the app and your bank will be linked. At this point, the transfer will be requested and will become available within 2-3 business days. Until they transfer, they'll be listed as "uncleared deposits" on the account tab of the app. After your bank is linked and verified, future deposits will take 2-3 business days.
If you are using your bank login information to link your bank with Stash, your transfer will be available within 2-3 business days.
Business days are Monday through Friday, with the exception of federal banking holidays.
