Is cash gift received from a friend taxable? if yes, what is the percentage and what are the conditions of getting it exempt

Yes it is taxable if cash received from freind is more than 50000 in a year otherwise it is exempt.
This is taxable at normal slab rate.

If you received cash more than Rs.50000/- then same is taxable.....

yes agree with both

so I believe there are no conditions to it. gift from anyone upto 50000 in a fy falls under exempt category

Yes there is no other condition in it but the limit of rs. 50000 in aggregate not a single.
For example if you receive 25000 from Mr. A and 35000 from Mr. B.
You receive 60000 in cash in F. Y. Therefore the entire amount is taxable.

There is no tax liability if you receive any gift either in cash or in kind from relative i. e. If you receive cash from relative exceeding Rs. 50000 is not taxable

by relative do you mean any distant relative or only the blood relations?
thanks in advance for the explanation.
