Please note the issue. In march, 12 I raised invoice of Rs. 110/- (100 as basic and 10 as service tax assumed). Now in Oct, 12 client wrote me mail that invoice is wrong. actual basic should be 90 only. Now I reversed complete transaction and new scenario is bill of Rs. 99 (Rs. 90 as basic and 9 as service tax) Problem is that I have paid Rs. 10 to government. NOw I cant revise the return. but I have received only Rs. 9 from my client. What should be accouting treatment.???? and how should I recover loss of Rs. 1 either from government or from my client. and howww?????? Thsnkks,
