As per section 139(1) read with section 44AB of the Income Tax Act, 1961 the due date for filing of Income Tax Returns and Tax Audit Reports by tax payers being Company and others required to get accounts audited under Income Tax Act, 1961 or under any other law or working partners of firm required to be audited under any law is the 30th September of the following year. The tax payers whose business receipts exceed Rupees One Crore or professional receipts exceed Rupees twenty-five Lakh during the previous year 2015-16 are required to file an Income Tax return accompanied by an audit report by the above mentioned due date. 

However, taking into consideration that the last date for making declarations under the Income Declaration Scheme 2016 is also 30th September, 2016, the Central Board of Direct Taxes has decided to extend the last date for such Income Tax Returns and Tax Audit Reports which were due on 30th September, 2016 to 17th October, 2016 in order to remove inconvenience and to facilitate ease of compliance.

For Order issued by the CBDT in this regard under section 119 of the Income-tax Act, 1961;
