Tata Sons easily crosses the RBI's cutoff for this category, with assets worth ₹1.75 lakh crore, well above the ₹1 lakh crore mark.
Other Tata companies like Tata Industries and Tata Capital Housing Finance are in a lower tier that doesn't require listing.
Meanwhile, there's ongoing debate inside the group about whether or not to list Tata Sons on the stock market, but no final call yet.
