Out sir's client carry on business of computer courses on which provide servicetax @ 10.30 on students fees. client is pvt ltd company in previous year we pay servicetax only students collection as per rule cash basis but current year service tax paid on due basis. sir our client's students dropped out ratio is very high. suppose a student registerd with fees is 30,000/- so liability of service tax is 2801.45/- paid on 5th of next month from the date of students registration. suppose student paid 1000/-at the time of registration and after they leave the course there was loss of s.tax which is not recover from student. so there is lot of burden of s.tax in these case sir what your suggestion to decrease the overburden of s.tax?
