SIGTAS V1 is considered a legacy sistem in Tax Authority. The Government of Timor-Leste through Tax Authority has initiated a project to upgrade the existing SIGTAS V1. I am leading the Project as the Project Manager. The project is now entering the second phase which is the Infrastructure and Change Management. The SIGTAS V1 upgrade to V3 is expected to go live on December 2020.
