Article 202 mandates that the Tax Authority must issue official Tax Cards to all active establishments, Omani companies, and permanent establishments once the system is launched. This automatic issuance applies only to those entities that have already complied with their data notification duties under Article 11. This provision ensures that compliant taxpayers are promptly provided with the identification needed for government transactions (as required by Article 16 bis), effectively rewarding early compliance with the Law's data registration requirements.
