The Central Board of Indirect Taxes and Customs (CBIC) has issued Circular No. 266/12/2026-GST dated October 28, 2026, addressing the distinction between research and development (R&D) services and consultancy services under GST.
The clarification follows the recommendations of the 57th GST Council meeting held on October 8, 2026, and aims to promote uniformity in the interpretation and application of GST provisions.

GST Exemption for Research and Development Services
The issue dates back to the 54th GST Council meeting held on September 9, 2024. At that meeting, the Council recommended an exemption for specified research and development services provided by eligible government entities, research associations, universities, colleges and other institutions notified under clauses (ii) or (iii) of Section 35(1) of the Income-tax Act, 1961, where consideration is received in the form of grants.
This exemption was subsequently introduced with effect from October 10, 2024, through Entry No. 44A of Notification No. 12/2017-Central Tax (Rate).
The Council also recommended examining the definition of research and development to clarify how such services should be distinguished from consultancy services.
Why Was a Clarification Required?
One of the key issues was the absence of specific definitions of terms such as research, research and development, consulting and consultancy under the CGST Act, 2017, the rules and notifications issued under it, and the explanatory notes to the scheme of classification of services.
The distinction is important when determining whether a particular service falls within the scope of the exemption available for eligible R&D services provided against grants.
The latest circular addresses this issue as part of the government's effort to ensure a more consistent interpretation of GST provisions.
