Statement of Financial Transactions registration requires ITDREIN issuance and officer activation with OTP for compliant e filing. Reporting persons must furnish a Statement of Financial Transactions in the prescribed form; registration on the e filing portal yields an ITDREIN that cannot be deactivated. Post registration, reporting entities submit entity details and register a Designated Director and Principal Officer, who complete activation via emailed link and OTP SMS. The Directorate prescribes procedural, data structure and security standards for secure capture, transmission, archival and retrieval of SFT data.
