Stripe Connect is integrated on our platform with Standard connect accounts with transactions processed as separate charges and transfers. With Standard connect accounts, the account is controlled directly by the account holder, AKA your individual sellers. They own and manage the relationship with Stripe, therefore they would be in charge of filing their own taxes. Stripe would contact the account holder (your sellers) directly with any required tax forms. The responsibility does not fall on you to file taxes on behalf of your sellers.
