Indian taxation laws one of the hardest to understand in the world. But, once you understand it, sky is the limit for your career.

I know Sagar personally.. he is a kind and good hearted person.. speaking about his knowledge, he possesses extremely vast knowledge about Indian & International tax laws which comes from his reading and also his real life experiences.
He is a good teacher who will go out of the way to make sure that his students or his friends get a good clarity of tax laws. He wont stop un till you understand the subject thoroughly. One of the best tutor and a good friend in this time.
