The Reserve Bank of India (RBI) has officially rejected an application from Tata Sons, the holding company of India's largest business conglomerate, to surrender its certificate of registration (CoR). Tata Sons had sought to be reclassified as an unregistered Core Investment Company (CIC) to avoid the mandatory public listing requirement. However, the central bank's decision has now cleared the path for the public listing of the group, which operates across diverse sectors and multiple countries, while according to a report by ET, the RBI communicated its decision in a letter dated September 11 2026, stating that after considering the application submitted on March 28 2024 and subsequent discussions, it couldn't approve the voluntary surrender of the CoR.
Regulatory Compliance and NBFC-UL Guidelines
The RBI has advised Tata Sons to take all necessary steps to ensure full compliance with the guidelines and directions applicable to Non-Banking Financial Companies in the Upper Layer (NBFC-UL), while this development signifies that the regulatory framework governing NBFC-UL entities will continue to apply to Tata Sons. The central bank's directive has effectively closed the regulatory loophole that Tata Sons attempted to use to bypass the public listing mandate. In March 2024, the company had applied to surrender its registration as a Core Investment Company (CIC). The RBI has also included Tata Sons in its list of 16 Upper-Layer NBFCs, which subjects the company to rigorous regulatory oversight and makes listing a mandatory requirement. While Tata Sons has not commented on the matter, the RBI has also maintained silence regarding the specific details of the rejection.
Asset Valuation and Scale-Based Framework
The central bank's decision is rooted in the scale-based regulatory framework introduced in June 2026. Under these rules, any company with an asset size exceeding 1 lakh crore is classified as an Upper-Layer NBFC. 01 lakh crore, which is more than double the established limit. In an attempt to secure de-registration and avoid listing, the company had reportedly cleared all its debts. However, according to RBI conditions, only companies that don't hold public funds, have no direct customer interface, and possess assets worth less than 1000 crore are eligible for de-registration by the December 31 deadline. Tata Sons, with its massive asset base, failed to meet these criteria.
Historical Context and Stakeholder Impact
Tata Sons, whose business interests range from steel and automobiles to financial services and semiconductors, has been categorized as an Upper-Layer NBFC since 2022. The central bank has clarified that once an NBFC is placed in the Upper Layer, it must remain under strict regulatory rules for at least five years, even if subsequent reviews suggest it no longer meets the eligibility criteria. RBI Governor Sanjay Malhotra previously noted that the revised rules for Upper-Layer NBFC classification are based on specific principles. He emphasized that based on these principles, the status of companies on the list is clear, addressing the question of whether Tata Sons would remain in the Upper Layer.
Implications for Tata Trusts and SP Group
The decision has significant implications for the major shareholders of Tata Sons, while tata Trusts, which holds a 66 percent stake through the Sir Ratan Tata Trust and Sir Dorabji Tata Trust, had passed a resolution in July 2025 to keep the holding company under private ownership. 37 percent stake, views the listing as a practical way to unlock value. The SP Group intends to sell a portion of its holding to repay part of its estimated 60000 crore debt. Currently, some of its shares in Tata Sons are pledged to raise funds, making the public listing a potentially beneficial move for their financial restructuring.
