All companies registered in India like private limited company, one person company, limited company, and section 8 company must file MCA annual return and income tax return each year. Before filing annual return, the company must conduct an Annual General Meeting at the end of each financial year. For newly incorporated Companies, the Annual General Meeting should be held within 18 months from date of incorporation or 9 months from the date of closing of financial year, whichever is earlier. Subsequent Annual General Meetings should be held within 6 months from the end of that financial year. In India, normally the financial year starts on April 1st and end on 31st March. So a Company's annual return would be due on or before September 30th.
