Q 5. It is not possible many a times to establish a one-to-one link between quantum of input services used in the course or furtherance of business by a supplier. In such situations, how distribution of ITC by the ISD is to be done? Ans. In such situations, distribution would be based on a formula. Firstly, distribution would be done only amongst those recipients of input tax credit to whom the input service being distributed are attributable. Secondly, distribution would be done amongst the operational units only. Thirdly, distribution would be done in the ratio of turnover in a State or Union territory of the recipient during the period to the aggregate of all recipients to whom input service being distributed is attributable. Lastly, the credit distributed should not exceed the credit available for distribution.
