The document discusses various transitional provisions under GST relating to input tax credit (ITC). Section 140 provides for ITC on taxes paid under previous laws including CENVAT credit carried forward and unavailed credit on capital goods. It also allows credit of eligible duties on inputs held in stock or contained in final products on the appointed GST date. Certain conditions must be satisfied for claiming this ITC. If conditions are not met, deemed credit will be allowed at a prescribed rate subject to specified limitations and safeguards. Precautions for availing ITC and deemed credit provisions are also summarized.
