Both tax consultancy firms BMR and Deloitte refused to comment on the proposed merger.
However, according to industry sources, Deloitte in an internal communication has indicated that it would merge BMR's corporate tax practice with itself.
BMR Advisors offers a host of tax, risk and M&A advisory services for domestic and global business of all sizes.
It was formed in October 2004 by Mukesh Butani and Bobby Parikh, along with Rajeev Dimri.
In April this year, a team of 38 lawyers of BMR Legal, a sister firm, had joined the M&A practice of Shardul Amarchand Mangaldas.
Deloitte is one of the world's leading consultancy firms.
