Ind AS norms, which are converged with global standards IFRS, can be followed by corporates on a voluntary basis from April 1 this year.
For companies having networth of Rs 500 crore or more, the new norms would be mandatory from April 1, 2016.
In a notification, the Corporate Affairs Ministry said the 'Companies (Ind AS) Rules 2015' would come into force from April 1, 2015.
Last month, the ministry had announced the Ind AS roadmap. Banking, insurance and non-banking finance companies are exempted from the roadmap.

The deadline would be applicable for other entities having networth of Rs 500 crore or more. It would also apply for holding, subsidiary, joint venture or associate companies of these two class of entities.
Ind AS would be mandatory from April 1, 2017, for companies -- whose equity and/or debt securities are listed or are in the process of being listed within India or outside -- having a networth of less than Rs 500 crore.
Holding, subsidiary, joint venture or associate companies of these entities would have to comply with this deadline.
Companies whose securities are listed or in the process of listing on SME exchanges would not be required to apply Ind AS. Such companies shall continue to comply with the existing accounting standards unless they choose otherwise.
"Any company opting to apply the Ind AS voluntarily... for its financial statements shall prepare its financial statements as per the Ind AS consistently," the Ministry's notification, dated February 16, said.
In his Budget speech in July 2014, Finance Minister Arun Jaitley had said there was an urgent need to converge the current Indian accounting standards with International Financial Reporting Standards (IFRS).
"The notification of these IFRS converged standards fills up significant gaps that exist in the current accounting guidance... This will in turn improve India's place in global rankings on corporate governance and transparency in financial reporting," Sai Venkateshwaran, Head of Accounting Advisory Services, KPMG in India said in a statement.
