What is the billing rate from clients for freshers hired by big IT companies in India?

Thanks for the A2A. Freshers (< 1yr exp) are usually not billed to the client. They are used as shadow resources with their cost covered in the billing rates of other resources. Only in exceptional cases where the fresher demonstrates exceptional grasp over the project and becomes indispensable, will the client be willing to pay for the fresher, in which case the billing rate would be below $30 per hour. Companies cannot show freshers as anything else since usually the customer will want to know the profile of each resource working on the project, and such malpractice might result in serious consequences. I am not sure what taboo you speak of. If you can elaborate on this in a comment, I would certainly reply if I know the answer. Hope this helps.

Let me put it in a simple way. Your 1 month salary = 1 day bill Your annual income = 1 month bill Avg bill amount 130$/hour It is depends on various factors, such as client, the company, type of project, etc
