Context:

The active workforce of STIB-MIVB is nearly 10,000 people, working across sites located in the Brussels region. Providing transportation services to the population, a large part of the staff works in the Business Unit Tram, Bus, and Metro. STIB-MIVB has all the necessary internal administrative support for the smooth running of all its activities and implements everything required to comply with the law.

In this context, STIB-MIVB aims to prepare for compliance with the Belcotax 2.0 and eGov 3.0 LTDS declaration (Loondata‑Transfert / Salary Data Transfer) programs, which are modernization initiatives of the Belgian Social e-Government aimed at fundamentally transforming data exchanges between employers, payroll partners, and social security institutions.

A new declarative model is being introduced, oriented around data, events, and registers, intended to gradually replace historical mechanisms such as DMFA and DRS.

The eGov 3.0 program aims to modernize exchanges between institutions by improving the reliability and updating of social data. This makes it possible to simplify the granting of social rights, reduce administrative procedures, and better adapt to the labor market.

However, this also affects the management of HR and payroll data, particularly in terms of data management, corrections, and compliance controls. Thus, the shift is from periodic and aggregated declarations to more frequent exchanges.

The technical impacts are significant and notably include the adaptation of data models, the implementation of new exchange interfaces, the strengthening of quality controls, and the management of a transitional phase of coexistence between old and new flows.
