Form MGT-8 is a certification that must be provided by a practicing company secretary along with certain companies' annual returns. It is required for listed companies, companies with paid-up capital over Rs. 10 crore, or companies with turnover over Rs. 50 crore. The secretary certifies that the annual return discloses correct and adequate facts and that the company has complied with the Companies Act. The secretary must examine registers, records, meetings, related party transactions, and other corporate filings and activities. Non-compliance can result in fines up to Rs. 5 lakh for the secretary, disciplinary action, and imprisonment of up to 10 years for the company if fraud is involved.
