Companies must file (regardless as to whether it was active or not) within 30 business days starting from the day after its date of registration. Close corporations must file (again regardless as to whether it was active or not) starting from the first day of the month it was registered up until the month thereafter. It may still file after such period, but an additional penalty fee will be applicable.
