No, you are not legally required to complete the checklist. However, you are encouraged to use the checklist to check if you meet the criteria of a platform operator.
Please note however that the checklist is meant to be a self-help resource. It does not constitute legal advice and is not definitive in determining whether you are a platform operator or not, because it depends on the specific circumstances of your company. You should still seek legal advice if you are unsure whether you are a platform operator.
After you have self-assessed to be a platform operator, you must notify MOM. Failure to notify MOM could result in an administrative penalty.
