I disagree.
If no one was interested in retail, why would Y-Combinator - One of the biggest angel investors in the USA buy a 7% stake in ClearTax - Whose main focus is retail.
ClearTax is willing to Audit F&O ITR4 for Rs 6,500 but I am sure if a big firm like Zerodha ties up with it, they would definitely be willing to give atleast 20% discount - Which would come to Rs 5,000.
Last year, they tied up with Paytm to provide its users with e-tax filing.
So, anything is possible. Why doesn't Nithin just write an email to those guys. No harm in trying, right?
