The QI Agreement requires that a QI complete the required US tax reporting on Forms 1042 and 1042-S regarding non-US clients, and potentially Form 1099 regarding US clients. In addition, FATCA compliance is a condition of maintaining QI status, thus any FATCA reporting must be performed.

Forms 1042-S and 1099 must be submitted to the IRS electronically.

Note that Forms W-8 are not filed with the IRS.
