All contact about CRS and MDES is initially via email CRSSintmaarten@sintmaartengov.org

The choice to communicate only by e-mail has to do with the fact that several parties are involved in AEOI / CRS, such as the tax authorities, the MDES application manager, the IT company, the OECD, etc.

In order to address a question and/or issue​ about CRS or MDES to the right person without miscommunication, a single point of contact and only one e-mail address has been chosen.
