"My Net ITC is already computed after the deduction as per Rule 42. Now, for refund calculation, am I again required to apply the proportionate formula by including exempted turnover in the adjusted total turnover? Wouldn't that amount to a double deduction?"
Adjusted Total Turnover Computation
Rule 89(4)(E) defines Adjusted Total Turnover as including turnover in a State/Union territory and zero-rated/non-zero-rated services while excluding the value of exempt supplies other than zero-rated supplies for the relevant period. To prevent double deduction in refund claims, practitioners should record full ITC in 4A5, compute required reversals under Rule 42/43, and reflect those reversals in 4B so the refund computation uses the gross ITC adjusted by the mandated reversals.
