Dear Chintan,

As already explained, filing of various forms with ROC is mostly event base. Some forms are required to be filed annually such as form 23AC, 23ACA (within 30 days of AGM) and 20B (within 60 days of AGM). However, remaining all forms are event base for example whenever a special resolution has been passed form 23 is required to be filed with ROC within 30 days of the date of resolution, when ever a charge is created or modified form 8 is required to be filed within 30 days of creation or modification of Charge and whenever a director is appointed or removed form 32 is requird to be filed with ROC within 30 days of appointment or removal. So it can not be a specific list.

However, you may go to www.mca.gov.in then mca21 link and then download form and get a list of all forms and purpose therefor.
