Under the proposed GST regime, both Centre and States will simultaneously levy GST across the value chain. Tax will be levied on supply of goods and services. Centre would levy and collect Central Goods and Services Tax (CGST), and States would levy and collect the States Goods and Service Tax (SGST) on all transactions within a State. The Centre would levy and collect the Integrated Goods and Services Tax (IGST) on all inter-State supply of goods and services. The proceeds of IGST will be apportioned between the States and the Centre, under the proposed Article 269A, as provided by Parliament by law on the recommendations of the GST Council. Further, the CGST collected by the Central Government as well as the Union’s share of IGST collected will be devolved to the States as per the provisions of Article 270.

The rates of GST will be recommended by the GST Council after it is constituted after the amendment of the Constitution.

This was stated by Shri Jayant Sinha, Minister of State in the Ministry of Finance in written reply to a question in Rajya Sabha.

IGST apportionment clarifies distribution between Centre and States under proposed GST, with CGST and SGST concurrent levy. Proposed GST provides for concurrent levy of CGST and SGST on intra State supplies and IGST on inter State supplies. IGST proceeds will be apportioned between Centre and States as prescribed by Parliament on the GST Council's recommendation, and CGST together with the Union's share of IGST will be devolved to States under constitutional fiscal devolution principles.
