Dear Yogita,
i am not agree with sathish, rahul
it is my opinion, based on past experience , that a request for reimbursement of expenses incurred in the course of working is not taxable
for a example any business guest will come in your office and you are provide lunch,snacks
then u are reimb. for lunch exp. during visit of official guest in the office this not a taxable
i hope your query is soved out
