My Question is ; I have a cenvat credit available of Rs 100. But I am providing taxable as well as exempted service. So I can utilise only Rs. 20. In the return I have showed credit availed Rs. 20 and utilised Rs. 20, instead of showing credit availed Rs. 100, utilised Rs. 20 and reversed Rs. 80. Now department is saying reverse credit as per ratio on Rs. 20 and pay the difference along with interest. Can this be saved?
