11 December 2025 – Plan to decommission MASNET (Updated)

Following our earlier announcement on “Plan to Decommission MASNET” dated 15 August 2025, we would like to provide an update on the status of MASNET services.

As part of MAS’ ongoing digital modernisation efforts, all MASNET services have been discontinued and migrated accordingly, with the following exceptions:

• Data Collection Gateway (DCG)
• eReturns Submission and Reporting System (ERSS)
• Key Appointment Holders - BIG (KAH)

DCG and ERSS will continue to be accessible via MASNET ID till further notice. Meanwhile, BIG (KAH) will be onboarded onto MAS-Tx in middle of December 2025. Access to MASNET will continue for one month until January 2026, after which access will be exclusively via MAS-Tx.
